Product Features
1. 100% mating compatible with MOLEX 43650 series Micro‑Fit 3.0 mating terminals & housings
2. Right‑angle horizontal single‑row structure, saves vertical PCB space
3. High‑temperature resistant thermoplastic housing, glow‑wire qualified for automotive‑grade requirements
4. Polarized shrouded housing prevents mis‑mating; built‑in PCB locating peg for precise assembly
5. Brass contact with tin/gold plating options, low contact resistance, anti‑vibration contact retention
6. Support through‑hole / SMT mounting; tape‑and‑reel packing available for auto‑insertion
7. RoHS, REACH SVHC compliant; low‑halogen material option available upon request
1. Drop‑in alternative for MOLEX 43650, eliminates redesign cost for dual‑sourcing
2. Strict dimensional tolerance control, stable normal‑force, avoids micro‑vibration disconnection risk
3. Automotive‑qualified raw‑material batch traceability, suitable for high‑reliability projects
4. Flexible options: tin/gold plating, through‑hole / SMT, tape‑reel / tray packing
5. Short lead‑time for standard positions, supports small‑batch prototype & mass‑volume orders
6. Full‑set supporting terminals & crimp housings available as one‑stop harness solution
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
