Frequently Asked Questions (FAQ)

Q: Can the Molex 0026482085 directly replace the TE Connectivity 3-644760-8 in existing designs?

A: Yes. Both connectors share identical pitch (0.156"), position count (8), row configuration (1), contact type (male pin), mounting method (through hole), termination (solder), shrouding (1 wall), and fastening mechanism (friction lock). The connectors are mechanically and electrically interchangeable for board-to-cable and board-to-wire applications.

Q: Are there differences in contact dimensions between these parts?

A: Minor dimensional variations exist. The TE Connectivity 3-644760-8 has a mating contact length of 0.400" (10.16mm) and overall contact length of 0.700" (17.78mm). The Molex 0026482085 has a mating contact length of 0.450" (11.43mm) and overall contact length of 0.750" (19.05mm). These differences do not affect mating compatibility but may impact clearance in space-constrained applications.

Q: What is the difference between the contact shapes?

A: The TE Connectivity 3-644760-8 features circular contact shapes, while the Molex 0026482085 features square contact shapes. Both configurations are compatible with standard 0.156" pitch receptacles and do not affect electrical performance or mating reliability.

Q: Do both parts meet the same compliance standards?

A: Both parts carry UL94 V-0 flammability ratings and EAR99 ECCN classifications. The TE Connectivity part is RoHS Compliant, while the Molex part is ROHS3 Compliant. ROHS3 represents an updated regulatory compliance status. Both parts are classified under HTSUS 8536.69.4040 and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What are the insulation material differences?

A: The TE Connectivity 3-644760-8 uses thermoplastic, glass-filled insulation material with natural color. The Molex 0026482085 uses polyester insulation material with black color. Both materials meet UL94 V-0 flammability requirements and are suitable for industrial applications.

Q: Are there voltage or current rating differences?

A: The TE Connectivity 3-644760-8 specifies a 600VAC voltage rating with current rating varying by wire gauge. The Molex 0026482085 does not specify voltage or current ratings in the provided data. For applications with specific voltage or current requirements, the TE Connectivity part's explicit 600VAC rating should be verified against application requirements.

Q: Which part should be selected for new designs?

A: Selection between these parts depends on application-specific requirements. The TE Connectivity 3-644760-8 is appropriate for designs requiring the MTA-156 series designation and explicit 600VAC rating specification. The Molex 0026482085 is appropriate for designs compatible with KK396 or 41671 series designations and offering the breakaway connector feature. Both parts meet identical electrical and mechanical compatibility criteria.

Q: What is the breakaway feature on the Molex connector?

A: The Molex 0026482085 is designated as a breakaway connector, indicating the connector can be separated into individual positions or smaller groups. This feature provides assembly flexibility for applications requiring modular connector configurations. The TE Connectivity 3-644760-8 does not include this breakaway capability.
