Substitute Part Grouping Explanation

Substitution of the M50-3100545P is based on electrical and mechanical compatibility within the Archer M50 series. The substitute part M50-3100545 maintains identical specifications across all critical parameters that determine functional interchangeability:

Key Parameters for Substitution:

• Connector type (Receptacle)
• Position count (10 positions)
• Pitch spacing (0.050" mating pitch, 0.050" row spacing)
• Mounting method (Surface Mount)
• Contact finish (Gold)
• Electrical ratings (1A, 250V)
• Operating temperature range (-40°C ~ 105°C)
• Compliance certifications (ROHS3, UL94 V-0)

The M50-3100545 is the direct equivalent part number, differing only in product status (Active vs. Obsolete) and packaging configuration (Tube vs. unspecified for the main part).

Parameter Comparison

Engineering Selection Recommendations

The M50-3100545 is the direct substitute for the M50-3100545P. Both parts are manufactured by Harwin Inc. and maintain identical electrical, mechanical, and environmental specifications. The substitute part carries Active product status, ensuring ongoing availability and supply chain support compared to the obsolete M50-3100545P.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for general purpose, medical, and telecommunications applications. The substitute part is supplied in Tube packaging, which is standard for production environments.

Selection of M50-3100545 over M50-3100545P is supported by product lifecycle status and inventory availability, with no compromise to functional or compliance requirements.

Frequently Asked Questions (FAQ)

Q: Are M50-3100545P and M50-3100545 electrically interchangeable?

A: Yes. Both parts are rated for 1A at 250V with identical contact materials (Phosphor Bronze), contact finish (Gold flash), and operating temperature range (-40°C ~ 105°C). Electrical performance is equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (M50-3100545P is Obsolete; M50-3100545 is Active) and packaging (M50-3100545 is supplied in Tube). All electrical, mechanical, and environmental specifications are identical.

Q: Can M50-3100545 be used as a direct replacement in existing designs?

A: Yes. The M50-3100545 maintains identical pitch spacing (0.050"), position count (10), row configuration (2 rows), mounting type (Surface Mount), and mated stacking heights (5.5mm, 6.18mm). PCB footprints and mating interfaces are compatible.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and classified under ECCN EAR99. Compliance certifications are identical.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Why is M50-3100545P marked as obsolete?

A: Product obsolescence reflects end-of-life status. The M50-3100545 (Active status) is the current production equivalent and should be used for new designs and ongoing procurement.
