TE Connectivity 640602-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640602-2 is a 2-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 24 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a free-hanging, in-line mounted component with locking ramp fastening. The part is currently active in production status with 827 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative part numbers may be necessary due to packaging availability, compliance status differences, or inventory requirements while preserving functional compatibility in the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the TE Connectivity 640602-2 is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Rectangular Receptacle)
• Number of positions (2)
• Contact type (Female Socket)
• Pitch specification (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge rating (24 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging, In-Line)
• Fastening type (Locking Ramp)
• Number of rows (1)
• Series designation (MTA-156)
• Contact finish thickness (80.0µin / 2.03µm)
• Color (White)

Environmental Parameters:

• Moisture Sensitivity Level (1 - Unlimited)

The substitute part 3-640602-2 maintains all electrical and mechanical parameters identical to the main part. Differences exist only in contact finish composition (tin versus tin-lead), packaging format (bulk versus standard), and regulatory compliance status (RoHS compliant versus non-compliant).

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 640602-2 and its substitute 3-640602-2 are active production parts suitable for new designs and existing applications requiring 2-position MTA-156 rectangular receptacle connectors with IDC termination for 24 AWG cable.

Compliance Considerations:

The 640602-2 is RoHS non-compliant with tin-lead contact finish. The 3-640602-2 substitute is RoHS compliant with tin contact finish. Selection between these parts depends on application regulatory requirements and end-use market restrictions. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications.

Inventory and Packaging:

The 640602-2 is available with 827 pieces in new original inventory in standard packaging. The 3-640602-2 substitute is available with 4555 pieces in bulk packaging. Bulk packaging availability may provide cost advantages for high-volume procurement.

Contact Finish Differences:

The primary technical difference is contact finish composition. The 640602-2 features tin-lead finish while the 3-640602-2 features tin finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm) and electrical performance characteristics. Contact finish selection is application-dependent and does not affect mechanical or electrical compatibility within the MTA-156 series.

Frequently Asked Questions (FAQ)

Q: Are the 640602-2 and 3-640602-2 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 2-position configuration, 0.156" pitch, female socket contact type, IDC termination method, and 24 AWG wire gauge rating. Electrical performance is equivalent.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 640602-2 uses tin-lead contact finish while the 3-640602-2 uses tin contact finish. Both finishes are applied to the same thickness (80.0µin / 2.03µm). Contact finish selection is determined by application requirements and regulatory compliance mandates. Tin-lead finish is associated with RoHS non-compliance, while tin finish is RoHS compliant.

Q: Can I use the 3-640602-2 as a direct replacement for the 640602-2 in existing designs?

A: Mechanical and electrical compatibility is maintained. Substitution is valid from a functional standpoint. Regulatory compliance status differs (RoHS compliant versus non-compliant), and contact finish composition differs (tin versus tin-lead). Verify application compliance requirements before substitution.

Q: What does "Feed Through" feature mean?

A: Feed Through indicates the connector design allows signal or power to pass through the connector body, enabling daisy-chain or series connection configurations within the MTA-156 series architecture.

Q: Are both parts suitable for new product designs?

A: Yes. Both the 640602-2 and 3-640602-2 are active production status parts. Selection for new designs should be based on regulatory compliance requirements (RoHS status) and contact finish specifications appropriate to the application environment.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage, handling, or assembly. This classification applies to both the main part and substitute.

Q: Does packaging format affect connector performance?

A: No. Packaging format (standard versus bulk) does not affect electrical or mechanical performance. Packaging selection is based on procurement volume requirements and inventory management preferences.

Q: Are the ECCN and HTSUS codes identical for both parts?

A: Yes. Both the 640602-2 and 3-640602-2 share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, indicating equivalent export control and tariff treatment.
