Key Parameters

Substitute Part Grouping Explanation

Substitution for the M50-3100945P is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Position count (18 positions)
• Pitch specification (0.050" / 1.27mm mating pitch)
• Row configuration (2 rows at 0.050" spacing)
• Mounting method (Surface Mount)
• Contact configuration (Female Socket)
• Fastening mechanism (Push-Pull)
• Electrical ratings (1A, 250V)
• Operating temperature range (-40°C ~ 105°C)
• Contact finish (Gold)
• Compliance certifications (ROHS3, UL94 V-0)

The M50-3100945 qualifies as a direct substitute based on matching all critical parameters while offering active product status and improved material specification.

Parameter Comparison

Engineering Selection Recommendations

The M50-3100945 is the direct equivalent for M50-3100945P applications. Both components maintain identical electrical, mechanical, and thermal specifications across all critical parameters. The primary distinction is product status: M50-3100945P is obsolete while M50-3100945 carries active status with current manufacturing support.

Material composition differs between the two parts (Nylon 6T versus Liquid Crystal Polymer), but both meet UL94 V-0 flammability requirements and ROHS3 compliance. The LCP insulation material in M50-3100945 provides enhanced dimensional stability and moisture resistance characteristics within the same operating envelope.

For new designs or ongoing production requiring this connector type, M50-3100945 is the appropriate selection. Existing designs using M50-3100945P can transition to M50-3100945 without modification to PCB layouts, mating interfaces, or electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can M50-3100945 directly replace M50-3100945P in existing assemblies?

A: Yes. Both connectors share identical pitch (0.050"), position count (18), row configuration (2 rows), mounting method (surface mount), and electrical ratings (1A, 250V). PCB footprints and mating interfaces are compatible.

Q: What is the significance of the insulation material difference?

A: M50-3100945P uses Nylon 6T while M50-3100945 uses Liquid Crystal Polymer (LCP). Both materials satisfy UL94 V-0 flammability and operate across -40°C to 105°C. LCP provides superior dimensional stability and moisture resistance, making it suitable for applications requiring tighter tolerances or high-humidity environments.

Q: Why is M50-3100945P listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. M50-3100945 represents the current active equivalent from Harwin Inc. for this connector configuration.

Q: Are there packaging differences between these parts?

A: M50-3100945P packaging is unspecified in available data. M50-3100945 is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both M50-3100945P and M50-3100945 are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8536.69.4040).
