Frequently Asked Questions (FAQ)

Q: Can the Molex 0050579421 directly replace the TE Connectivity 2-104257-0 in existing applications?

A: Yes. Both components are parametrically equivalent across all critical specifications: 21-position receptacle housings with 0.100" (2.54mm) pitch, female socket contacts, crimp termination, latch lock fastening, and identical environmental ratings. Direct substitution is supported without design modification.

Q: What is the primary reason for substituting the TE Connectivity 2-104257-0?

A: The TE Connectivity 2-104257-0 is classified as obsolete. The Molex 0050579421 provides an active, equivalent alternative to maintain supply continuity and ensure long-term component availability.

Q: Are there any differences in contact compatibility between these two housings?

A: Both housings accept crimp-terminated female socket contacts at 0.100" (2.54mm) pitch. Contact compatibility is determined by pitch and termination method, which are identical between the two components. Existing contact inventory remains compatible with either housing.

Q: Do both components meet the same regulatory and environmental standards?

A: Yes. Both the TE Connectivity 2-104257-0 and Molex 0050579421 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, confirming equivalent regulatory and environmental performance.

Q: What is the difference between the packaging specifications?

A: The TE Connectivity 2-104257-0 packaging is not specified in available documentation. The Molex 0050579421 is supplied in bulk packaging. Packaging format does not affect functional or mechanical compatibility.
