TE Connectivity 640601-9 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640601-9 is a 9-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features a tin-lead contact finish, free-hanging in-line mounting, and locking ramp fastening. The part is currently active in production with 1023 pieces in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative models may be required due to packaging variations, compliance status changes, or inventory availability considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 640601-9 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (9)
• Pitch specification (0.156" / 3.96mm)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Mounting type (Free Hanging In-Line)
• Series designation (MTA-156)

Allowable Variations:

• Contact finish composition (Tin-Lead to Tin)
• Contact finish thickness (within specified tolerance)
• Packaging format (individual to bulk)
• RoHS compliance status
• REACH vendor status

The substitute part 3-640601-9 maintains all mandatory parameters while varying only in contact finish material and packaging configuration, establishing direct substitutability within the MTA-156 rectangular connector family.

Engineering Selection Recommendations

Primary Selection: 640601-9

The 640601-9 is the baseline specification for applications requiring tin-lead contact finish. This part is active in production with established supply (1023 pieces in stock) and maintains the original MTA-156 design specification. Selection is appropriate for applications where tin-lead contact material is specified or where existing designs reference this exact part number.

Alternative Selection: 3-640601-9

The 3-640601-9 provides functional equivalence with RoHS compliance certification. This part maintains all electrical and mechanical parameters while substituting tin contact finish for the tin-lead composition of the primary part. The substitute is available in bulk packaging with higher inventory availability (1920 pieces in stock). Selection is appropriate for applications subject to RoHS regulatory requirements or where bulk packaging aligns with procurement workflows.

Compliance Considerations:

The 640601-9 is RoHS non-compliant and REACH-affected. The 3-640601-9 achieves RoHS compliance while maintaining ECCN and HTSUS classifications identical to the primary part. Both parts carry MSL rating 1 (unlimited moisture sensitivity), indicating no special storage or handling requirements.

Contact Finish Implications:

The transition from tin-lead to tin contact finish in the substitute part does not alter electrical performance, mating force, or mechanical durability within the MTA-156 connector family. Both finishes meet the 80.0µin (2.03µm) thickness specification and maintain equivalent contact resistance characteristics for 22 AWG IDC terminations.

Frequently Asked Questions (FAQ)

Q: Can 3-640601-9 be used as a direct replacement for 640601-9 in existing designs?

A: Yes. The 3-640601-9 maintains all critical electrical and mechanical parameters: 9-position receptacle configuration, 0.156" pitch, female socket contacts, IDC termination for 22 AWG cable, free-hanging in-line mounting, and locking ramp fastening. The contact finish variation from tin-lead to tin does not affect functional compatibility within the MTA-156 series.

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

A: The 640601-9 features tin-lead contact finish and is RoHS non-compliant. The 3-640601-9 features tin contact finish and is RoHS compliant. Both parts are identical in electrical performance, mechanical dimensions, and termination method. Packaging differs (standard versus bulk).

Q: Are there any mating compatibility issues between 640601-9 and 3-640601-9?

A: No. Both parts are receptacles within the same MTA-156 series and mate with identical plug connectors. The contact finish variation does not affect mating interface geometry or electrical contact characteristics.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements and supply chain strategy. For RoHS-compliant applications, specify 3-640601-9. For applications without RoHS requirements or where tin-lead finish is explicitly specified, use 640601-9. Both parts are active in production.

Q: Does the contact finish change affect current-carrying capacity?

A: No. Both tin-lead and tin finishes at 80.0µin (2.03µm) thickness provide equivalent electrical performance for 22 AWG IDC terminations. Current-carrying capacity is determined by the underlying copper conductor and contact geometry, not the plating material.

Q: What is the significance of the bulk packaging for 3-640601-9?

A: Bulk packaging indicates higher inventory availability (1920 pieces versus 1023 pieces) and may align with high-volume procurement workflows. Electrical and mechanical specifications remain unchanged. Packaging format does not affect connector performance or compatibility.

Q: Are both parts suitable for ribbon cable and discrete wire termination?

A: Yes. Both 640601-9 and 3-640601-9 support IDC termination for discrete or ribbon cable at 22 AWG. The IDC termination method and wire gauge specification are identical across both parts.

Q: What is the MSL rating and why is it relevant?

A: Both parts carry MSL rating 1 (unlimited), indicating no moisture sensitivity limitations. These connectors do not require special dry-pack storage, desiccant handling, or bake-out procedures prior to assembly.
