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:
- Molex: Micro-Fit 3.0 Series (43640 /43645 /43650 series)
- JST: 3.0mm pitch wire-to-board R/A SMD equivalent series
- TE (AMP): 3.0mm wire-to-board right-angle SMD connector equivalent
Note: Please verify pin count & PCB footprint before mass production.
Product Advantages
- Vibration-Resistant Lock: Positive locking avoids accidental disconnection for moving & vibrating equipment, solving the field failure risk of loose connections.
- Halogen-Free UL94V-0 Housing: Safe for industrial control, home appliance, and automotive accessory fire safety requirements.
- Full BOM Supply: One-stop purchase: SMD wafer + housing + crimp terminals, no multi-supplier sourcing hassle.
- Stable SMD Soldering: Optimized SMT foot, good solderability, low tombstone rate during PCB assembly.
- Cost-effective Alternative: Pin-to-pin compatible with international brands, reducing BOM cost without reliability compromise.
