Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-640431-3 is determined by strict alignment of the following parameters:

Critical Parameters (Must Match Exactly):

• Number of Positions: 13
• Pitch: 0.156" (3.96mm)
• Connector Type: Receptacle
• Contact Type: Female Socket
• Cable Termination: IDC
• Wire Gauge: 18 AWG
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Features: Closed End

Compatible Variation Parameters:

• Contact Finish: Tin or Tin-Lead (both acceptable for MTA-156 series)
• Contact Finish Thickness: 80.0µin (2.03µm) maintained across variants
• Color: Orange (consistent across series)
• Moisture Sensitivity Level: 1 (Unlimited) maintained

The substitute part 4-640431-3 maintains all critical parameters while offering an alternative contact finish specification (Tin versus Tin-Lead) and different regulatory compliance status. This substitution is valid for applications where the functional and mechanical requirements are identical.

Engineering Selection Recommendations

Primary Part Selection (1-640431-3): The 1-640431-3 is the recommended selection for new designs and applications requiring active product status support. This part maintains RoHS non-compliant status, which is appropriate for legacy systems and applications where lead-based contact finishes are acceptable or required. Active product status ensures ongoing availability and manufacturer support.

Substitute Part Selection (4-640431-3): The 4-640431-3 serves as a functional substitute where inventory of the primary part is unavailable. This part is classified as obsolete, indicating it is no longer in active production. The substitute offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulatory requirements. The contact finish specification changes from Tin-Lead to Tin, which maintains electrical performance characteristics while altering the material composition.

Selection Criteria:

• Use 1-640431-3 for new designs and applications requiring active product support
• Use 4-640431-3 only when 1-640431-3 is unavailable and ROHS3 compliance is required
• Verify that the application environment and regulatory framework support the selected contact finish specification
• Confirm that existing tooling and assembly processes are compatible with the selected part variant

Frequently Asked Questions (FAQ)

Q: Can the 4-640431-3 be used as a direct replacement for the 1-640431-3?

A: The 4-640431-3 is functionally compatible with the 1-640431-3 for applications where the mechanical and electrical requirements are identical. Both parts share the same 13-position configuration, 0.156" pitch, IDC termination method, and 18 AWG wire gauge. The primary difference is the contact finish specification (Tin versus Tin-Lead) and regulatory compliance status. Substitution is valid when the application does not require the specific material properties of tin-lead contacts and when obsolete product status is acceptable.

Q: What is the difference between Tin and Tin-Lead contact finishes?

A: Both Tin and Tin-Lead contact finishes are specified in this product family with identical contact finish thickness (80.0µin / 2.03µm). The contact finish material composition differs, with Tin-Lead containing lead and Tin containing only tin. This affects regulatory compliance classification and material properties. Selection depends on application requirements and regulatory framework applicability.

Q: Why is the 4-640431-3 marked as obsolete?

A: Obsolete product status indicates that the 4-640431-3 is no longer in active production by TE Connectivity. This classification does not affect functional compatibility with the 1-640431-3. Obsolete parts may have limited inventory availability and no ongoing manufacturer support. The part remains available from existing stock but should not be selected for new designs requiring long-term supply assurance.

Q: Are both parts suitable for IDC termination with 18 AWG cable?

A: Yes. Both the 1-640431-3 and 4-640431-3 are specified for IDC termination with 18 AWG discrete or ribbon cable. The IDC termination method and wire gauge specifications are identical across both parts, ensuring compatibility with the same cable assembly equipment and processes.

Q: What is the significance of the MTA-156 series designation?

A: The MTA-156 series designation indicates that both parts belong to the same connector family manufactured by TE Connectivity. This series designation ensures mechanical and electrical compatibility within the family. The 0.156" (3.96mm) pitch is the defining characteristic of the MTA-156 series, and all components within this series maintain this spacing standard.

Q: How does RoHS compliance affect part selection?

A: The 1-640431-3 is RoHS non-compliant, while the 4-640431-3 is ROHS3 compliant. RoHS compliance status determines regulatory acceptability in specific markets and applications. Applications subject to RoHS3 requirements must use the 4-640431-3. Applications without RoHS3 requirements can use either part based on availability and product status considerations.

Q: Are there any differences in moisture sensitivity between the two parts?

A: No. Both the 1-640431-3 and 4-640431-3 maintain identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited). This indicates that both parts have unlimited shelf life under standard storage conditions and do not require special moisture control measures during handling or storage.
