TE Connectivity 966444-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 966444-6 is a 6-position receptacle connector from the AMPMODU HV-100 series, designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts and tin-plated posts for reliable solder termination with push-pull fastening.

The 966444-6 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements for legacy systems utilizing this connector configuration.

Engineering Selection Recommendations

The substitute part 5-966444-6 is functionally equivalent to the obsolete 966444-6 across all critical electrical and mechanical parameters. Both parts share identical connector architecture, contact configuration, pitch specification, and termination methodology.

The primary distinction between these parts is product status: 5-966444-6 is currently active in production with RoHS compliance certification, while 966444-6 is obsolete with ROHS3 compliance. The substitute part carries UL94 V-0 material flammability rating, providing enhanced compliance documentation for new designs and production runs.

Contact finish thickness on the mating surface differs between the two parts (31.5µin versus 5.00µin), though both maintain gold plating. This variation does not affect functional compatibility or contact resistance performance within the specified application envelope.

For applications requiring the 966444-6, the 5-966444-6 substitute provides direct functional replacement with the advantage of active product status and current manufacturing support.

Frequently Asked Questions (FAQ)

Q: Are the 966444-6 and 5-966444-6 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 6-position configuration, 0.100" (2.54mm) pitch, through-hole mounting footprint, insulation height of 0.276" (7.00mm), and contact post length of 0.122" (3.10mm). They mount identically on printed circuit boards.

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

A: The 966444-6 is supplied in bulk packaging, while the 5-966444-6 is supplied in tray packaging. Packaging format does not affect connector performance or electrical characteristics.

Q: Why does the mating contact finish thickness differ between these parts?

A: Both parts utilize gold plating on mating contacts. The thickness variation (31.5µin versus 5.00µin) reflects manufacturing process differences between the obsolete and active production versions. Both thicknesses provide adequate gold coverage for reliable contact performance.

Q: Is the 5-966444-6 suitable for legacy system repairs?

A: Yes. The 5-966444-6 maintains full functional equivalence with the 966444-6 across all electrical and mechanical parameters. It is suitable for direct replacement in repair and maintenance applications.

Q: What compliance certifications apply to the substitute part?

A: The 5-966444-6 carries RoHS compliance certification and UL94 V-0 material flammability rating. Both parts are classified as MSL 1 (Unlimited) for moisture sensitivity and carry EAR99 export classification.

Q: Can these connectors be used interchangeably in new designs?

A: Yes. The 5-966444-6 is the active production equivalent and is suitable for new designs. Its active product status ensures ongoing manufacturing availability and supply chain support.
