Frequently Asked Questions (FAQ)

Q: What determines whether the Molex 0026604050 can substitute for the TE Connectivity 3-644611-5?

A: Substitution is valid when both connectors share identical specifications across connector type, contact type, number of positions, pitch, mounting method, termination type, fastening mechanism, shrouding configuration, contact shape, and compliance ratings. The Molex 0026604050 meets all these criteria.

Q: Are there differences in contact finish thickness between these connectors?

A: Yes. The TE Connectivity 3-644611-5 specifies 150.0µin (3.81µm) contact finish thickness on both mating and post surfaces. The Molex 0026604050 specifies 60.0µin (1.52µm) on both surfaces. Both finishes are tin-based and suitable for solder termination applications.

Q: Do these connectors have different insulation materials?

A: Yes. The TE Connectivity 3-644611-5 uses thermoplastic, glass-filled insulation material. The Molex 0026604050 uses polyester, glass-filled insulation material. Both materials achieve UL94 V-0 flammability rating and support the specified operating temperature range.

Q: What is the difference in insulation height between these parts?

A: The TE Connectivity 3-644611-5 has an insulation height of 0.545" (13.84mm). The Molex 0026604050 has an insulation height of 0.446" (11.33mm). This dimensional difference may affect board layout and clearance considerations in confined spaces.

Q: Are both connectors suitable for the same applications?

A: Both connectors are rated for general purpose and industrial applications. The Molex 0026604050 additionally lists automotive, medical, and telecommunications applications. Application suitability depends on specific system requirements beyond connector specifications.

Q: What is the contact length difference between these connectors?

A: The TE Connectivity 3-644611-5 has a contact length - post of 0.125" (3.18mm) and overall contact length of 0.700" (17.78mm). The Molex 0026604050 has a contact length - post of 0.140" (3.56mm) and overall contact length of 0.720" (18.29mm). These differences may affect mating depth and board-to-board spacing calculations.

Q: Are both connectors RoHS compliant?

A: Yes. The TE Connectivity 3-644611-5 is RoHS Compliant. The Molex 0026604050 is ROHS3 Compliant. Both satisfy RoHS requirements for restricted substance elimination.

Q: What is the moisture sensitivity level for both connectors?
