TE Connectivity 1-640442-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640442-1 is an 11-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as obsolete. Due to its obsolete product status and RoHS non-compliance, identification of equivalent substitute components is necessary for ongoing design support, maintenance, and new production applications requiring RoHS-compliant alternatives.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 4-640442-1 is the direct equivalent for the obsolete 1-640442-1. Selection of the substitute is based on the following engineering criteria:

Product Status: The main part 1-640442-1 is classified as obsolete, making the active-status substitute 4-640442-1 the appropriate choice for ongoing production and maintenance applications.

Regulatory Compliance: The substitute part 4-640442-1 is RoHS compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the substitute part satisfies these regulatory obligations.

Contact Finish Specification: The main part features tin-lead contact finish, while the substitute features tin contact finish. Both maintain identical contact finish thickness of 80.0µin (2.03µm), ensuring equivalent electrical performance and contact reliability.

Electrical and Mechanical Equivalence: All electrical parameters (11 positions, 0.100" pitch, 26 AWG, IDC termination, female socket contacts) and mechanical parameters (free hanging in-line/right angle mounting, locking ramp fastening, MTA-100 series) are identical between the main part and substitute, confirming direct functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 4-640442-1 substitute directly replace the 1-640442-1 in existing designs?

A: Yes. The 4-640442-1 maintains complete electrical and mechanical equivalence with the 1-640442-1 across all critical parameters including connector type, position count, pitch, contact configuration, termination method, and mounting style. Both connectors are from the MTA-100 series and accept identical 26 AWG discrete or ribbon cable.

Q: What is the primary difference between these two parts?

A: The primary differences are product status and regulatory compliance. The 1-640442-1 is obsolete and RoHS non-compliant with tin-lead contact finish. The 4-640442-1 is active, RoHS compliant, and features tin contact finish. Both maintain identical contact finish thickness and electrical performance.

Q: Are there packaging differences between the main part and substitute?

A: The main part 1-640442-1 has unspecified packaging, while the substitute 4-640442-1 is supplied in bulk packaging. This difference does not affect connector functionality or interchangeability.

Q: Does the change from tin-lead to tin contact finish affect performance?

A: No. Both contact finishes maintain the same thickness specification of 80.0µin (2.03µm). The tin finish in the substitute part provides equivalent electrical conductivity and contact reliability while supporting RoHS compliance requirements.

Q: Is the 4-640442-1 suitable for applications requiring RoHS compliance?

A: Yes. The 4-640442-1 is RoHS compliant, making it suitable for applications and markets with RoHS requirements. The 1-640442-1 is RoHS non-compliant and should not be used in RoHS-mandated applications.

Q: Can both parts be used interchangeably in the same assembly?

A: Yes. The electrical and mechanical specifications are identical, allowing both parts to function interchangeably within the same assembly. However, for new designs and ongoing production, the active substitute 4-640442-1 is the recommended choice due to its active product status and RoHS compliance.

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

A: Both the 1-640442-1 and 4-640442-1 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
