Engineering Selection Recommendations

All three substitute parts maintain active product status and meet UL94 V-0 flammability requirements. Selection between substitutes should be based on the following compliance and certification factors:

Amphenol ICC 67996-126HLF (BERGSTIK® II): RoHS compliant with REACH affected status. Operates across -65°C to 125°C temperature range with 3A per contact current rating. Gold or GXT™ contact finish provides enhanced corrosion resistance compared to tin plating.

Amphenol ICC 77313-101-26LF (BERGSTIK®): RoHS compliant with REACH unaffected status. Operates across -65°C to 130°C temperature range with 3A per contact current rating. Breakaway connector type matches the original Molex design. Gold or GXT™ contact finish with tin post plating.

3M 961226-6404-AR (Series 961): RoHS compliant with REACH unaffected status. Operates across -25°C to 105°C temperature range with 2A per contact current rating. Gold flash contact finish on mating surface with tin post plating. Narrower operating temperature range compared to Amphenol alternatives.

The Amphenol ICC 77313-101-26LF offers the closest functional alignment to the original Molex 0879142616, featuring breakaway design, extended temperature range, and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 67996-126HLF substitute for the Molex 0879142616 in all applications?

A: The 67996-126HLF meets all primary compatibility criteria including 26-position, 2-row configuration at 2.54mm pitch, male pin contacts, through-hole solder termination, and push-pull fastening. The primary difference is REACH affected status versus the original REACH unaffected designation. Verify REACH compliance requirements for your specific application before selection.

Q: What is the significance of contact post length variations between these connectors?

A: Contact post length variations (0.095" to 0.130") represent acceptable engineering tolerances within the through-hole solder termination category. These variations do not affect mating compatibility or electrical performance when used with standard PCB pad designs. Post length differences may impact solder joint geometry but remain within acceptable manufacturing standards.

Q: Why does the 3M 961226-6404-AR have a lower current rating than the Amphenol alternatives?

A: The 3M connector specifies 2A per contact versus 3A for Amphenol parts. This represents a design parameter difference in contact cross-section and material composition. Selection should be based on actual circuit current requirements. If your application requires greater than 2A per contact, the Amphenol alternatives are more suitable.

Q: Are gold-plated contacts compatible with tin-plated receptacles?

A: Gold-plated mating contacts on the substitute parts are compatible with tin-plated receptacles. Gold plating provides enhanced corrosion resistance and contact reliability. This represents an upgrade in contact finish quality compared to the original tin-plated design.

Q: What packaging differences exist between these substitute parts?

A: The Molex 0879142616 ships in trays, while Amphenol ICC 67996-126HLF ships in bags and 77313-101-26LF ships in bulk. The 3M 961226-6404-AR ships in bulk packaging. Packaging format does not affect connector functionality or compatibility but may impact inventory management and handling procedures.

Q: Which substitute part offers the widest operating temperature range?

A: The Amphenol ICC 77313-101-26LF (BERGSTIK®) operates across -65°C to 130°C, providing the widest temperature range among the substitutes. This specification exceeds the temperature coverage of both the 67996-126HLF (-65°C to 125°C) and the 3M 961226-6404-AR (-25°C to 105°C).
