Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0876313004 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 28 positions at 0.100" (2.54mm) spacing
• Physical Configuration: 4-row board edge mounting with through-hole solder termination
• Connector Architecture: Male pins and blades in right-angle orientation
• Contact Layout: 24 signal and 4 power contact distribution
• Electrical & Environmental Specifications: Gold contact finish at 30.0µin thickness, UL94 V-0 flammability rating, -20°C to 105°C operating range
• Compliance Standards: RoHS3 compliance and MSL 1 rating

The Amphenol ICC (FCI) 51425-001LF meets all these criteria, providing functional and mechanical equivalence as a direct substitute for the obsolete Molex part.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 51425-001LF is the qualified substitute for the obsolete Molex 0876313004. Both components share identical mechanical dimensions, electrical specifications, and environmental ratings. The Amphenol part maintains active product status, ensuring continued availability and manufacturing support. Both components meet RoHS compliance requirements and carry UL94 V-0 flammability certification. The contact finish specifications are equivalent at 30.0µin gold thickness, and both operate across the identical temperature range of -20°C to 105°C. The Amphenol part's PwrBlade® series designation indicates enhanced power handling capability while maintaining full backward compatibility with the original Molex design.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 51425-001LF be used as a direct replacement for the Molex 0876313004?

A: Yes. Both connectors share identical position count (28), pitch (0.100"), row configuration (4), mounting method (board edge through-hole right angle), and contact layout (24 signal, 4 power). Physical and electrical parameters are equivalent.

Q: What is the primary reason for substitution?

A: The Molex 0876313004 is classified as obsolete. The Amphenol ICC 51425-001LF provides equivalent functionality with active product status and ongoing manufacturing support.
