Electrical and Mechanical Compatibility: Both parts are identical in all critical functional parameters including connector type, position count, pitch, contact configuration, termination method, and wire gauge rating. Direct substitution is supported without circuit or mechanical redesign.

Inventory Availability: The substitute part maintains active inventory status with 910 pieces in stock, providing reliable supply chain access compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can 3-644807-2 be used as a direct replacement for 644807-2 in existing applications?

A: Yes. The parts are electrically and mechanically identical across all specified parameters. The substitute maintains the same 2-position configuration, 0.156" pitch, IDC termination for 18 AWG cable, and gold contact finish. Direct substitution is supported without modification to mating connectors or cable assemblies.

Q: What is the difference between 644807-2 and 3-644807-2?

A: The primary differences are product status and regulatory compliance. The 644807-2 is obsolete and RoHS non-compliant, while 3-644807-2 is active and RoHS Compliant. The substitute also carries REACH Unaffected status. All electrical and mechanical specifications remain identical.

Q: Are there packaging differences between these parts?

A: The main part 644807-2 does not specify packaging information. The substitute 3-644807-2 is supplied in Bulk packaging. Both parts are suitable for production assembly and integration into cable harnesses.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and material composition attribute that does not affect electrical or mechanical compatibility. The substitute part maintains identical contact materials, finishes, and performance characteristics. RoHS compliance of the substitute provides regulatory advantage for applications subject to environmental directives.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled under standard conditions without special moisture control measures.

Q: Are these parts suitable for ribbon cable applications?

A: Yes. Both parts support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) technology. The 18 AWG wire gauge rating applies to both cable types.
