The full part number is printed on the SOP-8 body (e.g., “APW7165” or “7165” abbreviated). Cross-reference with the board service manual or schematic if available. APW7165 is the most common variant in 19–24 inch LCD monitors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What other components should I check when replacing APW7xxx on an LCD power board?\u003c\/strong\u003e\u003cbr\u003eA: When replacing APW7xxx, also inspect: (1) the external power MOSFETs (often shorted when the controller fails), (2) bootstrap capacitor (typically 100nF ceramic), (3) output electrolytic capacitors (bulging = replace), (4) current-sense resistor for open circuit. Replacing only the IC without checking these often results in the new IC failing again.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can APW7302 replace APW7165 in an existing LCD power board?\u003c\/strong\u003e\u003cbr\u003eA: Only if the pinout and specifications match. APW71xx and APW73xx variants are not universally pin-compatible. Always compare the datasheet pinout of the original IC with the replacement before substituting. Verify input voltage range, switching frequency, and gate drive compatibility.\u003c\/p\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e5× APW7165 \/ APW7145 \/ APW7302 \/ APW7120 \/ APW7142 \/ APW7301 PWM Controller IC (SOP-8) — variant as selected\u003c\/li\u003e\u003c\/ul\u003e","brand":"Keszoox","offers":[{"title":"APW7145","offer_id":46991461581035,"sku":"14:350852#APW7145","price":5.92,"currency_code":"USD","in_stock":true},{"title":"APW7142","offer_id":46991461613803,"sku":"14:201659813#APW7142","price":5.56,"currency_code":"USD","in_stock":true},{"title":"APW7120","offer_id":46991461646571,"sku":"14:4044226#APW7120","price":4.96,"currency_code":"USD","in_stock":true},{"title":"APW7165","offer_id":46991461679339,"sku":"14:1202#APW7165","price":5.28,"currency_code":"USD","in_stock":true},{"title":"APW7301","offer_id":46991461712107,"sku":"14:10#APW7301","price":11.28,"currency_code":"USD","in_stock":true},{"title":"APW7302","offer_id":46991461744875,"sku":"14:351074#APW7302","price":5.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/apw7165-apw7145-apw7302-apw7120-apw7142-apw7301-sop-8-ic-chipset.webp?v=1761794278","url":"https:\/\/keszoox.com\/products\/apw7165-apw7145-apw7302-apw7120-apw7142-apw7301-pwm-controller-sop8-5pack","provider":"Keszoox","version":"1.0","type":"link"}
