Substitute Part Grouping Explanation
Substitution of the M50-3100745P is based on electrical and mechanical compatibility within the Archer M50 series. The substitute part M50-3100745 maintains identical specifications across all critical parameters that determine functional interchangeability:
- Connector type and contact configuration (14-position receptacle, female socket)
- Mating pitch and row spacing (0.050" / 1.27mm)
- Electrical ratings (1A, 250V)
- Operating temperature range (-40°C ~ 105°C)
- Surface mount termination and push-pull fastening
- Gold contact finish and UL94 V-0 flammability rating
- RoHS3 compliance and REACH unaffected status
The primary distinction between these parts is product status and packaging format, not functional or electrical characteristics.

Engineering Selection Recommendations
The M50-3100745 is the direct substitute for the obsolete M50-3100745P. Both parts are manufactured by Harwin Inc. within the same Archer M50 series and share identical electrical, mechanical, and environmental specifications.
Selection of M50-3100745 is supported by:
- Active product status ensuring ongoing availability and manufacturer support
- Identical compliance certifications (RoHS3, REACH unaffected, UL94 V-0)
- Tube packaging format suitable for automated assembly and inventory management
- No functional or performance differences relative to the obsolete variant
For applications currently using M50-3100745P, direct substitution with M50-3100745 requires no design modifications or re-qualification.
Frequently Asked Questions (FAQ)
Q: Can M50-3100745 directly replace M50-3100745P in existing designs?
A: Yes. Both parts are functionally and electrically identical. The M50-3100745 is the active production equivalent of the obsolete M50-3100745P. No design changes are required for substitution.
Q: What is the difference between M50-3100745P and M50-3100745?
A: The primary differences are product status and packaging. M50-3100745P is obsolete with unspecified packaging, while M50-3100745 is active and supplied in tube packaging. All electrical, mechanical, and environmental specifications are identical.
Q: Are there any compatibility concerns with PCB footprints or assembly processes?
A: No. Both parts share identical mounting type (surface mount), pitch (0.050"), row spacing (0.050"), insulation height (0.181"), and mated stacking heights (5.5mm, 6.18mm). PCB footprints and assembly processes require no modification.
Q: Do both parts meet the same compliance and certification standards?
A: Yes. Both M50-3100745P and M50-3100745 are RoHS3 compliant, REACH unaffected, and rated UL94 V-0 for material flammability. Moisture sensitivity level is 1 (unlimited) for both parts.
Q: What is the current availability status of these parts?
A: M50-3100745P is obsolete with 702 pieces in stock. M50-3100745 is active with 1684 pieces in stock. For new designs and ongoing production, M50-3100745 is the recommended selection.
