Substitute Part Grouping Explanation

Substitute parts for the 3M 961126-6700-AR-TP are qualified based on the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Pitch: 26 positions at 0.100" (2.54mm) mating pitch
• Mounting Technology: Surface mount solder termination
• Fastening Mechanism: Push-pull engagement
• Electrical Performance: Gold-plated mating contacts with tin-plated posts
• Environmental Compliance: UL94 V-0 flammability rating and MSL 1 classification

The identified substitute parts maintain these core parameters while offering active product status and enhanced specifications in certain areas.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compatibility with the core mechanical and electrical interface requirements of the 3M 961126-6700-AR-TP. Selection between alternatives should be based on the following factors:

Sullins GBC26SFBN-M30: Active product status with extended operating temperature range (-65°C ~ 150°C) and higher current rating (3A). Polyamide insulation material provides robust thermal and mechanical performance. ROHS3 compliant with documented compliance certifications.

Samtec TSM-126-02-S-SV: Active product status with cuttable header design offering design flexibility. Extended operating temperature range (-55°C ~ 125°C). Liquid Crystal Polymer insulation provides superior dimensional stability and thermal performance. ROHS3 compliant.

Both alternatives satisfy UL94 V-0 flammability requirements and MSL 1 moisture sensitivity classification, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Are these substitute parts mechanically compatible with the 3M 961126-6700-AR-TP?

A: Yes. All substitute parts maintain identical 26-position configuration at 0.100" (2.54mm) pitch with matching male pin contact geometry, unshrouded design, and push-pull fastening mechanism. Surface mount solder termination is consistent across all parts.

Q: What are the key differences between the substitute options?

A: The Sullins GBC26SFBN-M30 offers higher current rating (3A vs. 2A) and extended temperature range to 150°C. The Samtec TSM-126-02-S-SV features cuttable header design and Liquid Crystal Polymer insulation for enhanced dimensional stability. Both are active products with current manufacturing support.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All parts carry UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. The Sullins and Samtec parts are ROHS3 compliant, providing enhanced regulatory alignment for current production requirements.

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

A: The original 3M part uses Thermoplastic insulation. Sullins uses Polyamide (PA9T) Nylon 9T, and Samtec uses Liquid Crystal Polymer (LCP). These materials affect thermal stability and dimensional tolerance performance across the operating temperature range.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, for new designs and production transitions. The mechanical interface, electrical contact configuration, and termination method are identical. Verify that the extended operating temperature ranges and current ratings of the substitute parts meet or exceed your application requirements.
