Its 0.098" (2.50mm) pitch sets the PCB footprint and the per-contact current ceiling — at 3A the temperature rise stays within the PA66 housing's limit.
The 2.50mm pitch is wide enough for easy hand-soldering or wave-solder assembly, yet tight enough for compact layouts.
Sourced per RFQ against your BOM quantity.
If your BOM calls for a different circuit count, the same footprint rules apply across the series.
Yes, the B4B-EH-A includes a friction lock that secures the mating receptacle without requiring a secondary latch, providing vibration-resistant retention.
The B4B-EH-A mates with JST EH series crimp receptacle housings and the corresponding crimp terminals (e.g., SEH-001T-P0.6). The friction lock aligns with the receptacle's locking ramp.
