Engineering Selection Recommendations

All three substitute parts maintain active product status and meet UL94 V-0 flammability requirements, ensuring compliance with standard safety specifications. The Amphenol ICC BERGSTIK® series (77313-124-64LF and 77313-824-64LF) are RoHS Compliant with REACH Affected status, while the Hirose A1-64PA-2.54DSA(71) is RoHS Compliant with REACH Unaffected status. All parts carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special handling requirements during storage or assembly.

The Amphenol ICC 77313-124-64LF and 77313-824-64LF differ primarily in contact finish thickness on the mating surface (30.0µin versus 15.0µin), with the 77313-124-64LF providing thicker gold plating. The Hirose A1-64PA-2.54DSA(71) offers the thinnest mating finish (8.00µin) and operates across a narrower temperature range (-55°C to 85°C) compared to the Amphenol options (-65°C to 130°C).

Selection should be based on packaging requirements (tray versus bulk availability), operating temperature specifications, and contact finish durability needs for the specific application environment.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 77313-124-64LF directly replace the Molex 0901310952?

A: Yes. Both parts share identical core specifications: 64-position, 2-row configuration with 0.100" (2.54mm) pitch, through-hole solder termination, push-pull fastening, and unshrouded male pin contacts. Mechanical and electrical compatibility is maintained across PCB footprints and mating interfaces.

Q: What is the difference between the two Amphenol ICC BERGSTIK® options?

A: The 77313-124-64LF and 77313-824-64LF differ in mating contact finish thickness. The 77313-124-64LF provides 30.0µin (0.76µm) gold plating, matching the Molex original specification, while the 77313-824-64LF provides 15.0µin (0.38µm). Both maintain identical electrical performance and UL94 V-0 compliance.

Q: Is the Hirose A1-64PA-2.54DSA(71) suitable for high-temperature applications?

A: The Hirose part operates from -55°C to 85°C, which is narrower than the Amphenol BERGSTIK® range of -65°C to 130°C. Application selection should confirm that the Hirose operating temperature range meets system requirements.

Q: What packaging options are available?

A: The Molex 0901310952 and Hirose A1-64PA-2.54DSA(71) are supplied in trays, while the Amphenol ICC 77313-124-64LF and 77313-824-64LF are supplied in bulk packaging. Packaging selection depends on inventory management and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are RoHS Compliant. The Amphenol ICC parts carry REACH Affected status, while the Hirose part carries REACH Unaffected status. Regulatory compliance should be confirmed for the specific end-use application and geographic market.

Q: Do these connectors require special handling during storage?

A: No. All parts carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating standard storage conditions are acceptable without desiccant packaging or controlled humidity requirements.
