FAQ

Q: What is the difference between DJ70210-6.3-21 and DJ7022A-6.3-21?: A: Both are 6.3mm pitch female automotive connectors, but they differ in housing geometry, locking tab design, and body profile. The DJ70210 series has a distinct housing shape suited to specific OEM harness applications. Check your original connector before ordering.
Q: Is this connector waterproof?: A: This connector includes a rubber wire seal for moisture protection, but is not fully IP67 rated like dual-seal variants. It is suitable for protected engine bay environments. For full IP67 waterproofing, use a dual-seal DJ-series connector.
Q: What is the maximum current rating?: A: The DJ70210-6.3-21 is rated up to 20A per pin, suitable for relay wiring, fuse box circuits, and auxiliary power distribution.
