PHB2.0 Connector Complete Guide: Yeonho SMAW200, Dual Row Belt Lock, Specs, PCB Footprint & Comparison with HY2.0
The PHB2.0 connector is a 2.0mm pitch dual-row wire-to-board crimp connector with a belt lock (locking latch) mechanism, widely used in industrial equipment, robotics, 3D printers, and high-density wiring applications where a single-row HY2.0 connector does not provide enough circuits in the available board space.
Despite being one of the most commonly stocked dual-row 2.0mm connectors, the PHB2.0 is almost never documented with its official Yeonho part numbers — leaving engineers and sourcing teams unable to cross-reference datasheets, verify specifications, or find compatible mating parts.
This guide fills that gap completely.
The PHB2.0 connector is the generic market name for the Yeonho Electronics SMAW200 series — a 2.0mm pitch dual-row wire-to-board connector system documented under three Yeonho part number families: SMAW200-NNC (SMT wafer), SMW200-NNC (DIP wafer), and SMH200-NNC (wire housing). The crimp terminal is the YST200-C.
This guide covers the complete PHB2.0 / Yeonho SMAW200 specification, all housing and wafer part numbers from 12 to 40 pin, PCB footprint dimensions, terminal specifications, a detailed PHB2.0 vs HY2.0 comparison, and the key differences between the SMT and DIP wafer variants.
What Is the PHB2.0 Connector?
The PHB2.0 connector is a 2.0mm pitch dual-row wire-to-board crimp connector system with an integrated belt lock (locking latch) on the wire housing. It consists of four components:
- SMAW200-NNC wafer — SMT (surface mount) PCB header, dual row, 12–40 pin
- SMW200-NNC wafer — DIP (through-hole) PCB header, dual row, 12–40 pin
- SMH200-NNC housing — wire plug with belt lock latch, dual row, 12–40 pin
- YST200-C terminal — crimp contact, AWG#24~#26, Sn plated copper alloy
Key characteristics:
- 2.0mm pitch — same pitch as HY2.0 (single row), but dual-row configuration doubles circuit density
- 3A AC/DC current rating — same as HY2.0 single row
- 250V AC/DC voltage rating
- Belt lock (locking latch) — positive retention mechanism prevents accidental disconnection
- Dual row — 12 to 40 total pins (6–20 pins per row), even numbers only
- Two wafer options — SMT (SMAW200) or DIP through-hole (SMW200)
- AWG#24 ~ #26 wire gauge
- Vibration rated — contact resistance 50mΩ MAX, discontinuity 1μsec MAX
- RoHS compliant (Halogen-Free)

PHB2.0 = Yeonho SMAW200 = SMH200-NNC: The Naming Explained
The PHB2.0 connector system has multiple names across its three components, causing significant confusion in sourcing and cross-referencing:
| Market Name | Yeonho Part | Type | Description |
|---|---|---|---|
| PHB2.0 | SMAW200-NNC | SMT Wafer | Surface mount PCB header, dual row |
| PHB2.0 | SMW200-NNC | DIP Wafer | Through-hole PCB header, dual row |
| PHB2.0 | SMH200-NNC | Wire Housing | Dual-row wire plug with belt lock |
| PHB2.0 | YST200-C | Terminal | Crimp contact, AWG#24~#26 |
The part number suffix -NNC decodes as: NN = pin count (e.g., 12C = 12-pin, 40C = 40-pin), C = series designation for the dual-row locking variant.
Relationship to HY2.0 (SMH200): The PHB2.0 housing (SMH200-NNC) shares the same terminal dimensions and the same 2.0mm pitch as the HY2.0 single-row system (SMH200-NN). The “C” suffix indicates the dual-row configuration with belt lock. The wafer series changes from 20037WR (HY2.0 single-row) to SMAW200/SMW200 (PHB2.0 dual-row).

PHB2.0 vs HY2.0: Dual Row vs Single Row at 2.0mm Pitch
➡️ Shop PHB2.0 | Shop HY2.0
PHB2.0 and HY2.0 share the same 2.0mm pitch and identical electrical ratings, but serve fundamentally different wiring needs. The key difference is row configuration and locking mechanism.
| Feature | PHB2.0 (SMAW200/SMH200-NNC) | HY2.0 (SMH200) |
|---|---|---|
| Pitch | 2.0mm | 2.0mm |
| Row configuration | Dual row | Single row |
| Current rating | 3A AC/DC | 3A AC/DC |
| Voltage rating | 250V AC/DC | 250V AC/DC |
| Pin count range | 12 ~ 40 (dual row, even numbers) | 2 ~ 18 (single row, even numbers) |
| Locking mechanism | Belt lock (positive latch) | Friction fit only |
| Wafer options | SMT or DIP | DIP only (20037WR) |
| Housing | SMH200-NNC (dual row) | SMH200-NN (single row) |
| Terminal | YST200-C | YST200 |
| PCB hole diameter | φ0.8mm (DIP) / SMT pad | φ1.0mm (DIP only) |
| Circuit density | 2× higher (dual row) | Standard |
| Vibration rated | Yes (1μsec MAX) | Yes (1μsec MAX) |
When to choose PHB2.0 over HY2.0:
- You need more than 18 circuits (PHB2.0 goes to 40 pin)
- You need positive locking — belt lock prevents accidental disconnection in vibration environments
- You need SMT wafer option (PHB2.0 offers SMAW200 SMT; HY2.0 is DIP only)
- Board space is limited — dual row doubles circuit density in the same footprint width
- High-density wiring harnesses for industrial, robotics, or automotive applications
When to choose HY2.0 over PHB2.0:
- You need 2–10 circuits (HY2.0 starts at 2 pin; PHB2.0 minimum is 12 pin)
- Your board already has a 20037WR single-row header
- Simpler wiring with fewer circuits where dual-row density is not needed

Wire preparation for YST200-C:
- Strip insulation: 2.0–2.5mm
- Wire gauge: AWG#24 (0.20mm²) or AWG#26 (0.13mm²)

PHB2.0 PCB Footprint (PCB Pattern Dimensions)
For PCB designers using the SMW200-NNC DIP wafer, the official PCB pattern dimensions from the Yeonho SMAW200-NNC datasheet are:
| Parameter | Dimension |
|---|---|
| Contact pitch (column) | 2.0mm |
| Contact pitch (row) | 2.0mm |
| Pad hole diameter | φ0.8mm |
| Row-to-row distance | 2.0mm |
PCB pattern width (A dimension) by pin count: A = (N/2 − 1) × 2.0mm, where N = total pin count. Example: 12-pin = 10.0mm, 24-pin = 22.0mm, 40-pin = 38.0mm.
Note: hole diameter φ0.8mm is smaller than HY2.0 single-row (φ1.0mm) — note this difference when designing dual-use PCBs.

Frequently Asked Questions
What is a PHB2.0 connector?
The PHB2.0 connector is the generic market name for the Yeonho Electronics SMAW200 series — a 2.0mm pitch dual-row wire-to-board crimp connector with belt lock, rated 3A, 250V. It consists of an SMAW200-NNC (SMT) or SMW200-NNC (DIP) PCB wafer, SMH200-NNC dual-row wire housing with belt lock, and YST200-C crimp terminal (AWG#24~#26). ➡️ Shop PHB2.0 at Keszoox
Is PHB2.0 the same as Yeonho SMAW200?
Yes. PHB2.0 is the generic market name for the Yeonho Electronics SMAW200 connector series. The complete system uses SMAW200-NNC (SMT wafer), SMW200-NNC (DIP wafer), SMH200-NNC (wire housing with belt lock), and YST200-C (crimp terminal).
What is the difference between PHB2.0 and HY2.0?
PHB2.0 (SMAW200) is the dual-row, belt-lock version; HY2.0 (SMH200) is the single-row, friction-fit version. Both use 2.0mm pitch and identical electrical ratings (3A, 250V). PHB2.0 covers 12–40 pin; HY2.0 covers 2–18 pin. PHB2.0 adds a positive locking latch and offers SMT wafer option. They are not interchangeable. ➡️ Shop HY2.0
What is the current rating of PHB2.0?
The PHB2.0 (Yeonho SMAW200) is rated 3A AC/DC at 250V AC/DC. ➡️ Shop PHB2.0 Connectors
What is the PHB2.0 PCB footprint?
The SMW200-NNC DIP wafer uses φ0.8mm hole diameter, 2.0mm column pitch, 2.0mm row pitch. Width A = (N/2 − 1) × 2.0mm where N = total pin count. Note: φ0.8mm is smaller than HY2.0 single-row (φ1.0mm).
Does PHB2.0 have a locking mechanism?
Yes. The SMH200-NNC wire housing has an integrated belt lock (locking latch) that positively retains the housing to the wafer, preventing accidental disconnection in vibration environments.
What wire gauge does PHB2.0 use?
PHB2.0 uses AWG#24 ~ #26 wire with the YST200-C crimp terminal. Pre-crimped cables available in UL1007 PVC and UL3239 Silicone (200°C).
Is PHB2.0 RoHS compliant?
Yes. The Yeonho SMAW200 / PHB2.0 series is Halogen-Free and RoHS compliant.
What crimp tool for PHB2.0?
Use a ratchet crimper with 1.9mm die (conductor wings) and 1.6mm die (insulation wings) for the YST200-C terminal. The Engineer PA-09 or IWISS SN-2549 work well for AWG#24~#26. ➡️ Full Crimping Guide →
