Customer Selection Guide

1. Confirm position count: 2‑12P, match original MOLEX 43650 position number
2. Select mounting style: Through‑hole for strong mechanical hold; SMT tape‑reel for high‑speed SMT assembly
3. Plating selection: Tin‑plating for general‑cost signal circuits; gold‑plating for high‑vibration / long‑life‑cycle scenarios
4. Check wire gauge: 20‑30 AWG; actual current must apply temperature‑derating curve
5. Always mate our housing with matched‑spec terminals; mixing different‑vendor terminals may degrade contact performance
6. For automotive projects: request material certificate, CPK report, compliance document before mass‑production
