• Contact finish: Gold-plated mating surface
• Insulation height: 0.169" (4.30mm)
• Contact post length: 0.098" (2.50mm)
• Current rating: 1A
• Operating temperature range: -40°C ~ 105°C
• Flammability rating: UL94 V-0
• Insulation material: Thermoplastic

The 25630401RP2 maintains electrical and mechanical compatibility with the original 3M part across all critical interface dimensions and performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The NorComp 25630401RP2 is the recommended substitute for the obsolete 3M 950504-6102-AR. The substitute part maintains active product status with confirmed inventory availability (1117 pcs), ensuring long-term procurement viability. Both parts share identical electrical ratings, mechanical dimensions, and UL94 V-0 flammability compliance. The NorComp part carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The contact material difference (phosphor bronze vs. copper alloy) and glass-filled insulation in the substitute part provide equivalent or enhanced performance characteristics within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are the 3M 950504-6102-AR and NorComp 25630401RP2 pin-compatible?

A: Yes. Both connectors maintain identical 0.079" (2.00mm) pitch, 4-position configuration, and through-hole solder termination. Mating interface dimensions are equivalent.

Q: What is the voltage and current rating for the NorComp substitute?

A: The NorComp 25630401RP2 is rated for 1A current. The voltage rating specification was not provided in the available data; however, the connector maintains the same physical contact geometry and insulation height as the original 3M part.

Q: Does the glass-filled thermoplastic insulation affect compatibility?

A: No. The glass-filled insulation in the NorComp part provides enhanced mechanical and thermal stability while maintaining the same external dimensions and electrical isolation properties required for this application.

Q: What is the difference in contact material between the two parts?

A: The 3M part uses copper alloy contacts while the NorComp part uses phosphor bronze. Both materials are suitable for gold-plated mating surfaces and tin-plated posts in this connector class, with phosphor bronze offering improved spring characteristics.

Q: Is the NorComp part RoHS compliant?

A: Yes. The NorComp 25630401RP2 is RoHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the operating temperature range for the substitute part?

A: The NorComp 25630401RP2 operates across -40°C to 105°C, matching the original 3M specification.
