3M 950536-6102-AR Equivalent & Substitute Parts

Part Overview

The 3M 950536-6102-AR is a 36-position rectangular receptacle connector with 0.079" (2.00mm) pitch, designed for through-hole PCB mounting with gold-plated mating contacts. This connector operates across -40°C to 105°C and carries a 1A current rating at 1000V. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 950536-6102-AR is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle or header configuration with 36 positions to maintain mating compatibility
• Pitch Specification: 0.079" (2.00mm) pitch is mandatory for mechanical and electrical alignment
• Mounting Method: Through-hole termination required for PCB integration
• Contact Configuration: Female socket contacts with push-pull fastening
• Operating Temperature: Minimum -40°C to 105°C range to support original application envelope
• Electrical Ratings: Current and voltage ratings must meet or exceed 1A and 1000V respectively
• Flammability Compliance: UL94 V-0 rating preferred for safety-critical applications

Two substitute parts meet these criteria with documented compatibility:

MMS-136-01-T-SV (Samtec Inc.): Active product with enhanced current rating (3.9A per contact), extended temperature range (-55°C to 105°C), and ROHS3 compliance. Contact finish differs (tin vs. gold mating surface).

NPPN361BFCN-RC (Sullins Connector Solutions): Active header configuration with gold mating contact finish matching the original, 2A current rating, and UL94 V-0 flammability rating. Connector type differs (header vs. receptacle).

Parameter Comparison

Engineering Selection Recommendations

For Direct Receptacle Replacement: MMS-136-01-T-SV provides the closest functional match as an active receptacle connector with identical pitch, position count, and through-hole mounting. The tin mating contact finish differs from the original gold specification but maintains electrical continuity. This part carries ROHS3 compliance and an extended operating temperature range, supporting modern manufacturing standards. Current capacity exceeds the original 1A specification.

For Gold Contact Finish Requirement: NPPN361BFCN-RC maintains gold mating contact finish and UL94 V-0 flammability rating identical to the original. The header configuration (versus receptacle) requires mating with a compatible receptacle connector. This part is ROHS3 compliant and carries 2A current rating. Selection depends on whether the mating connector can accommodate a header interface.

For Obsolete Product Support: Both substitute parts are active products with current manufacturing support and documented availability. MMS-136-01-T-SV is recommended for applications where receptacle configuration is mandatory. NPPN361BFCN-RC is recommended where gold contact finish and UL94 V-0 compliance are critical design requirements.

Frequently Asked Questions (FAQ)

Q: Can MMS-136-01-T-SV replace 950536-6102-AR directly in existing designs?

A: MMS-136-01-T-SV is mechanically and electrically compatible as a receptacle connector with identical pitch and position count. The tin mating contact finish differs from the original gold specification. Designs requiring gold contact finish should evaluate NPPN361BFCN-RC or confirm that tin contact compatibility is acceptable for the application.

Q: What is the difference between a receptacle and header connector?

A: A receptacle connector accepts pins from a mating header connector. The 3M 950536-6102-AR is a receptacle. NPPN361BFCN-RC is a header and requires a compatible receptacle for mating. MMS-136-01-T-SV is also a receptacle and mates with compatible header connectors.

Q: Does the tin contact finish of MMS-136-01-T-SV affect electrical performance?

A: Tin and gold are both acceptable contact finishes for electrical connectivity. Tin provides corrosion resistance and is widely used in industrial applications. Gold provides superior corrosion resistance in high-humidity or harsh environments. Selection depends on application requirements and environmental exposure.

Q: Are both substitute parts RoHS compliant?

A: Yes. MMS-136-01-T-SV and NPPN361BFCN-RC are both ROHS3 compliant, meeting current environmental and manufacturing standards. The original 3M part RoHS status is not specified.

Q: What is the current rating difference between the parts?

A: The 3M 950536-6102-AR carries 1A current rating. MMS-136-01-T-SV carries 3.9A per contact, and NPPN361BFCN-RC carries 2A. Both substitutes exceed the original specification, providing design margin for current-sensitive applications.

Q: Can I use NPPN361BFCN-RC as a direct replacement?

A: NPPN361BFCN-RC is a header connector, not a receptacle. It cannot directly replace a receptacle connector. Use this part only if your design can accommodate a header interface or if you are redesigning the mating connector configuration.
