Cross Reference / Alternative Replacement

Our MX3.0 R/A SMD connector is mechanically & electrically interchangeable with the series, a direct drop-in replacement for cost-down:

  1. Molex: Micro-Fit 3.0 Series (43640 /43645 /43650 series)
  2. JST: 3.0mm pitch wire-to-board R/A SMD equivalent series
  3. TE (AMP): 3.0mm wire-to-board right-angle SMD connector equivalent

Note: Please verify pin count & PCB footprint before mass production.

Product Advantages 

  1. Vibration-Resistant Lock: Positive locking avoids accidental disconnection for moving & vibrating equipment, solving the field failure risk of loose connections.
  2. Halogen-Free UL94V-0 Housing: Safe for industrial control, home appliance, and automotive accessory fire safety requirements.
  3. Full BOM Supply: One-stop purchase: SMD wafer + housing + crimp terminals, no multi-supplier sourcing hassle.
  4. Stable SMD Soldering: Optimized SMT foot, good solderability, low tombstone rate during PCB assembly.
  5. Cost-effective Alternative: Pin-to-pin compatible with international brands, reducing BOM cost without reliability compromise.

Application 

✅ Industrial automation, servo control, PLC peripheral
✅ Home appliances: Air conditioner, washing machine, power supply module
✅ Automotive auxiliary electronics, vehicle lighting & sensor harness
✅ Power & signal transmission for robotics, medical equipment, battery management system
