Engineering Selection Recommendations

The Amphenol ICC (FCI) 51915-051LF is the qualified substitute for the obsolete Molex 0876642004. Selection is based on the following engineering criteria:

Parameter Equivalence: The 51915-051LF maintains identical electrical and mechanical specifications across all critical dimensions, including 31-position count, 0.100" pitch, 4-row configuration, board-edge right-angle mounting, and solder termination.

Compliance Status: Both parts meet UL94 V-0 flammability requirements and operate across the identical temperature range of -20°C to 105°C. The 51915-051LF carries active RoHS compliance status, ensuring regulatory alignment for current production environments.

Contact Specifications: Gold plating at 30.0µin (0.76µm) thickness is maintained on the 51915-051LF, with the option of enhanced GXT™ gold finish for applications requiring extended contact durability.

Product Availability: The transition from obsolete to active product status provides supply chain continuity and eliminates long-lead-time constraints associated with legacy component procurement.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 51915-051LF be used as a direct replacement for the Molex 0876642004?

A: Yes. The 51915-051LF meets all specified electrical and mechanical parameters for direct substitution, including position count, pitch, row configuration, mounting type, termination method, and contact specifications.

Q: What are the key differences between these two connectors?

A: The primary differences are manufacturer identity and product status. The 51915-051LF is manufactured by Amphenol ICC (FCI) and maintains active product status, whereas the 0876642004 is obsolete. Both parts are electrically and mechanically equivalent.

Q: Are there any compliance or certification differences?

A: Both connectors meet UL94 V-0 flammability requirements and operate across -20°C to 105°C. The 51915-051LF carries active RoHS compliance, while the 0876642004 is ROHS3 compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What packaging is available for the substitute part?

A: The Amphenol ICC 51915-051LF is supplied in tray packaging, suitable for automated assembly and high-volume production environments.

Q: Does the contact finish differ between the two parts?
