Engineering Selection Recommendations

The 3-640442-7 is the direct substitute for the obsolete 640442-7. Both parts are manufactured by TE Connectivity and belong to the MTA-100 series with identical mechanical and electrical specifications.

Product Status Consideration: The 640442-7 is obsolete, while the 3-640442-7 is active. Selection of the active substitute part ensures continued availability and support for future procurement requirements.

Compliance Consideration: The 3-640442-7 is RoHS compliant, whereas the 640442-7 is RoHS non-compliant. Applications subject to RoHS regulations require the 3-640442-7. The contact finish difference (tin versus tin-lead) reflects this compliance distinction while maintaining equivalent electrical and mechanical performance.

Inventory Consideration: The 3-640442-7 has significantly higher inventory availability (8158 pieces versus 834 pieces), supporting both immediate and sustained production needs.

Both parts share identical pitch, position count, mounting configuration, IDC termination method, wire gauge compatibility, and fastening mechanism, confirming direct functional interchangeability in all applications.

Frequently Asked Questions (FAQ)

Q: Can the 3-640442-7 be used as a direct replacement for the 640442-7?

A: Yes. The 3-640442-7 is a direct substitute with identical connector type, position count, pitch, mounting configuration, fastening method, cable termination type, and wire gauge specifications. Both parts are MTA-100 series receptacles with 7 positions at 0.100" pitch designed for 26 AWG IDC termination.

Q: What is the difference between the tin-lead finish on the 640442-7 and the tin finish on the 3-640442-7?

A: The contact finish difference reflects RoHS compliance status. The 640442-7 uses tin-lead finish and is RoHS non-compliant. The 3-640442-7 uses tin finish and is RoHS compliant. Both finishes maintain the same contact finish thickness of 80.0µin (2.03µm) and provide equivalent electrical performance.

Q: Are there packaging differences between these parts?

A: The 640442-7 packaging is not specified in available documentation. The 3-640442-7 is supplied in bulk packaging. Both parts are identical in form, fit, and function for connector mating and cable termination applications.

Q: Why is the 640442-7 classified as obsolete?

A: The 640442-7 is an older product designation within the MTA-100 series. The 3-640442-7 represents the current active equivalent, offering improved compliance status and superior inventory availability.

Q: What applications are these connectors suitable for?

A: These 7-position MTA-100 receptacle connectors are designed for discrete or ribbon cable termination using IDC technology at 26 AWG wire gauge. The locking ramp fastening and closed-end design provide secure mating for industrial and telecommunications applications requiring reliable in-line or right-angle connector configurations.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both the 640442-7 and 3-640442-7 have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.

Q: Can these connectors accommodate different wire gauges?

A: No. Both parts are specified for 26 AWG wire only. The IDC termination mechanism is designed specifically for this wire gauge with discrete or ribbon cable configurations.
