This equivalence ensures direct interchangeability in existing circuit designs and PCB layouts without modification to schematic or layout documentation.

Packaging Consideration: The substitute part 3-641126-7 is supplied in bulk packaging, compared to the original part's unspecified packaging. Bulk packaging is standard for active production components and does not affect functional performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can 3-641126-7 be used as a direct replacement for 641126-7 in existing designs?

A: Yes. The 3-641126-7 is a direct functional equivalent with identical electrical and mechanical specifications. No design modifications are required for substitution.

Q: What is the primary reason for substituting 641126-7?

A: The 641126-7 is classified as obsolete. The 3-641126-7 is the active equivalent part maintained in current production by TE Connectivity AMP Connectors, ensuring long-term availability and supply chain continuity.

Q: Are the contact specifications identical between these parts?

A: Yes. Both parts feature identical male pin contacts with copper alloy material, gold mating surface finish (15.0µin thickness), and tin post finish (150.0µin thickness). Contact dimensions, including mating length (0.295"), post length (0.140"), and overall length (0.535"), are identical.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts operate across the identical temperature range (-55°C to 105°C), carry UL94 V-0 flammability rating, maintain MSL 1 (Unlimited) moisture sensitivity level, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Both are RoHS compliant.

Q: What is the difference in packaging between these parts?

A: The 641126-7 packaging specification is not defined in available documentation. The 3-641126-7 is supplied in bulk packaging, which is standard for active production components. Bulk packaging does not affect electrical performance or mechanical compatibility.

Q: Are there any electrical performance differences between these connectors?

A: No. Both parts carry identical voltage rating (250VAC), current rating specification (varies by wire gauge), and all contact electrical properties. Electrical performance is equivalent.

Q: Can these parts be intermixed in the same assembly?

A: Yes. The identical pitch (0.100"/2.54mm), position count (7), row configuration (1 row), and all mechanical dimensions ensure full interchangeability in board-to-cable/wire applications.

Q: What is the significance of the "3-" prefix in the substitute part number?

A: The "3-" prefix indicates a variant designation within the TE Connectivity AMP Connectors product line. The base product number (641126) remains identical, confirming functional equivalence. The prefix distinguishes the active production variant from the obsolete original.
