TE Connectivity 640435-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640435-5 is a 5-position rectangular receptacle connector from the MTA-156 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 product status.

Due to its obsolete classification, locating equivalent or substitute components is necessary for ongoing system maintenance, repair, and new design implementations. Active production alternatives within the same series provide functional compatibility while offering improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 640435-5 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 5 positions at 0.156" (3.96mm) spacing
• Termination Technology: IDC cable termination for 26 AWG wire
• Mounting & Form Factor: Free hanging in-line configuration
• Series Classification: MTA-156 series membership

The substitute part 3-640435-5 maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional compatibility. The primary distinction lies in contact finish composition and product status classification.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Active Production Systems:

The substitute part 3-640435-5 is the appropriate selection. This part maintains active product status and achieves RoHS compliance, aligning with current regulatory requirements and manufacturing standards. The transition from tin-lead to tin contact finish does not alter electrical or mechanical compatibility within the MTA-156 series specification.

For Legacy System Maintenance:

The original 640435-5 remains functionally equivalent for repair and replacement applications where existing tin-lead contact specifications are already established in the system. However, the 3-640435-5 substitute provides equivalent performance with improved compliance posture.

Compliance Considerations:

The 3-640435-5 substitute achieves RoHS compliance, whereas the original 640435-5 is RoHS non-compliant. Both parts maintain identical moisture sensitivity levels and export classification codes. The contact finish composition change from tin-lead to tin does not introduce compatibility issues within the specified wire gauge and termination method parameters.

Frequently Asked Questions (FAQ)

Q: Can the 3-640435-5 directly replace the 640435-5 in existing assemblies?

A: Yes. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 5-position configuration, 0.156" pitch, IDC termination for 26 AWG cable, female socket contacts, and free hanging in-line mounting. The contact finish composition change from tin-lead to tin does not affect functional compatibility.

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

A: The 3-640435-5 is an active production part with RoHS compliance, while the 640435-5 is obsolete and RoHS non-compliant. The contact finish differs (tin versus tin-lead), but both maintain 80.0µin (2.03µm) thickness and identical performance characteristics within the MTA-156 series.

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

A: The 640435-5 packaging is unspecified in the documentation. The 3-640435-5 is supplied in bulk packaging. Both parts are available in new original condition with substantial inventory levels.

Q: Does the tin contact finish affect signal integrity or electrical performance?

A: No. Both tin and tin-lead finishes at 80.0µin (2.03µm) thickness meet the electrical requirements for IDC receptacle connectors in the MTA-156 series. Contact finish composition does not alter the connector's electrical characteristics for this application.

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

A: Both the 640435-5 and 3-640435-5 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both connectors support discrete or ribbon cable termination at 26 AWG wire gauge using the IDC termination method.
