Engineering Selection Recommendations

Both Amphenol ICC (FCI) substitute parts maintain active product status and full RoHS compliance, ensuring long-term availability and regulatory alignment. The Molex 0702800820 is ROHS3 compliant, while the substitute parts are RoHS compliant, both meeting current environmental standards.

The primary distinction between the two Amphenol ICC alternatives lies in contact finish thickness on the mating surface: 77313-124-64LF specifies 30.0µin (0.76µm), while 77313-824-64LF specifies 15.0µin (0.38µm). Both maintain identical post finish thickness of 78.7µin (2.00µm) and equivalent electrical performance at 3A per contact.

Selection between substitute parts should be based on specific application requirements regarding contact durability and wear characteristics. Both parts are suitable for automotive, general purpose, lighting, medical, and telecommunications applications where the original Molex part is specified.

Frequently Asked Questions (FAQ)

Q: Can Amphenol ICC 77313-124-64LF or 77313-824-64LF be used as direct replacements for Molex 0702800820?

A: Yes. Both parts meet all critical substitution parameters including pitch, position count, row configuration, mounting type, and termination method. Functional compatibility is established through identical connector geometry and electrical specifications.

Q: What is the difference between the two Amphenol ICC substitute parts?

A: The primary difference is contact finish thickness on the mating surface. Part 77313-124-64LF has 30.0µin (0.76µm) gold plating, while 77313-824-64LF has 15.0µin (0.38µm). Both maintain equivalent electrical performance and UL94 V-0 flammability rating.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: Contact length specifications differ between the original and substitute parts. Molex 0702800820 has overall contact length of 0.595" (15.11mm), while both Amphenol ICC parts have 0.480" (12.19mm). Verify PCB design and mating connector specifications to ensure mechanical clearance and proper engagement depth.

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

A: Both substitute parts are RoHS compliant and maintain UL94 V-0 flammability rating. The original Molex part is ROHS3 compliant. All parts have MSL 1 (Unlimited) moisture sensitivity level and EAR99 ECCN classification.

Q: What is the operating temperature range for these connectors?

A: The Amphenol ICC substitute parts are rated for -65°C to 130°C operation. The Molex 0702800820 operating temperature is not specified in the provided data.
