Engineering Selection Recommendations

Both the 77313-893-72LF and 3-826632-6 maintain active product status and meet UL94 V-0 flammability requirements. The 77313-893-72LF supports an extended operating temperature range to 130°C, while the 3-826632-6 operates to 105°C. The 3-826632-6 provides higher current capacity at 5A per contact versus 3A for the primary part. Contact geometry variations exist in mating length, post length, and insulation height; these differences require verification against specific PCB footprint and mating connector specifications. Both parts maintain identical pitch, row spacing, and MSL 1 classification. Selection between these parts depends on application temperature requirements, current demands, and mechanical fit constraints within the target assembly.

Frequently Asked Questions (FAQ)

Q: Can 3-826632-6 be used as a direct replacement for 77313-893-72LF in all applications?

A: Substitution is valid only when the application tolerates the specified parameter variations. The 3-826632-6 operates to 105°C maximum versus 130°C for the 77313-893-72LF, and contact geometry differs in mating length (0.264" vs 0.236"), post length (0.126" vs 0.189"), and insulation height (0.110" vs 0.100"). PCB footprint compatibility and mating connector specifications must be verified.

Q: What are the key electrical differences between these parts?

A: The 3-826632-6 is rated for 5A per contact compared to 3A for the 77313-893-72LF. Both parts use identical pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), and termination method (solder). Both maintain gold-plated mating contacts and tin-plated posts.

Q: Are there material composition differences that affect performance?

A: Yes. The 77313-893-72LF uses phosphor bronze contacts with thermoplastic insulation, while the 3-826632-6 uses brass contacts with polybutylene terephthalate (PBT) insulation. These material differences may affect mechanical durability, thermal characteristics, and chemical resistance depending on the application environment.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-0 rated and RoHS compliant. The 77313-893-72LF is RoHS Compliant, while the 3-826632-6 is ROHS3 Compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: What packaging differences exist between these parts?

A: The 77313-893-72LF is supplied in Bag packaging, while the 3-826632-6 is supplied in Bulk packaging. This affects handling, storage, and inventory management but does not impact functional compatibility.

Q: Which part should be selected for high-temperature applications?

A: The 77313-893-72LF supports operation to 130°C, making it suitable for applications requiring extended temperature range. The 3-826632-6 is limited to 105°C maximum operating temperature.
