Application Scenarios & Design Considerations

Disconnectable Insulation displacement connectors

Alternative Part Number

  • BM04B-SRSS-TB --: Same SRSS series 1.0mm pitch 4-pin shrouded header but with through-hole vertical pins instead of surface mount, offering a compatible mating interface with the SHR series housing.
  • SM04B-SRSS-TF --: Same SRSS 1.0mm pitch 4-pin surface-mount header in a different packaging option, electrically and mechanically compatible with the original footprint.
  • 53398-0471 --: Molex PicoBlade 1.25mm pitch 4-pin vertical surface-mount header, a widely available cross-series alternative for compact wire-to-board connections when a slight pitch change is acceptable.
