Engineering Selection Recommendations

The Molex 0026645050 connector is the primary substitute for the obsolete TE Connectivity 3-644614-5. Selection of this alternative is supported by the following factors:

Product Status: The Molex 0026645050 maintains active product status, ensuring ongoing availability, manufacturing support, and supply chain continuity. The TE Connectivity part's obsolete classification creates supply risk and limits future procurement options.

Regulatory Compliance: Both connectors achieve ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements. Both carry UL94 V-0 flammability ratings, confirming suitability for applications requiring flame-resistant materials.

Functional Equivalence: The Molex connector matches all critical electrical and mechanical parameters of the TE Connectivity original, including 5-position configuration, 3.96mm pitch spacing, right-angle through-hole mounting, friction lock fastening, and solder termination. Both connectors support identical mating contact lengths and square contact geometry.

Electrical Specifications: While the Molex part does not specify voltage and current ratings in the provided data, both connectors share identical contact materials (tin finish), contact geometry, and flammability classifications, establishing electrical compatibility within the original application envelope.

Mechanical Compatibility: Dimensional alignment of mating contact lengths (0.450" / 11.43mm) and identical shrouding configuration (shrouded 1-wall) ensure mechanical interchangeability in existing board layouts and cable assemblies.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026645050 directly replace the TE Connectivity 3-644614-5 in existing designs?

A: Yes. Both connectors share identical pitch spacing (0.156" / 3.96mm), position count (5), mounting orientation (right-angle through-hole), shrouding configuration (1-wall), and contact geometry (square, tin-finished). Direct substitution is supported without design modification.

Q: What is the primary reason for substituting the TE Connectivity part?

A: The TE Connectivity 3-644614-5 carries obsolete product status, creating supply availability and long-term support risks. The Molex 0026645050 maintains active status, ensuring reliable procurement and manufacturing continuity.
