Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-640602-7 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (17)
• Pitch specification (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge (24 AWG)
• Number of rows (1)
• Mounting configuration (Free Hanging In-Line)
• Contact type (Female Socket)
• Series designation (MTA-156)

The substitute part 4-640602-7 maintains identical electrical and mechanical specifications across all mandatory parameters, ensuring direct functional equivalence. The primary distinction between the main part and substitute relates to product status, contact finish composition, and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 4-640602-7 serves as the direct substitute for the obsolete 1-640602-7 based on the following engineering criteria:

Functional Equivalence: Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, termination method, and wire gauge. Physical and electrical interchangeability is established.

Product Status: The 1-640602-7 is classified as obsolete, indicating discontinued production. The 4-640602-7 maintains active product status, ensuring availability for procurement and ongoing supply chain support.

Regulatory Compliance: The 4-640602-7 achieves RoHS compliance, whereas the 1-640602-7 is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the 4-640602-7 is the appropriate selection.

Contact Finish Specification: The 1-640602-7 features tin-lead contact finish, while the 4-640602-7 utilizes tin finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm). The tin finish in the 4-640602-7 aligns with modern manufacturing standards and RoHS requirements.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the 4-640602-7 directly replace the 1-640602-7 in existing applications?

A: Yes. The 4-640602-7 maintains identical electrical and mechanical specifications across all critical parameters. Physical dimensions, pitch, position count, termination method, and wire gauge compatibility are equivalent, enabling direct substitution in existing designs and assemblies.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: The 1-640602-7 uses tin-lead finish, while the 4-640602-7 uses tin finish. Both maintain the same contact finish thickness (80.0µin / 2.03µm). The tin finish in the 4-640602-7 complies with RoHS directives that restrict lead content in electronic components. For new designs or RoHS-regulated applications, tin finish is the current standard.

Q: Why is the 1-640602-7 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by TE Connectivity. The 4-640602-7 represents the active production equivalent, ensuring continued availability and supply chain reliability.

Q: Are there any packaging differences between these parts?

A: The 1-640602-7 packaging is not specified in available documentation. The 4-640602-7 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the MSL rating, and does it affect storage or handling?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity. These connectors do not require special moisture-controlled storage conditions or baking procedures prior to assembly.

Q: Are both parts classified under the same ECCN and HTSUS codes?

A: Yes. Both the 1-640602-7 and 4-640602-7 share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications, indicating equivalent export control and tariff treatment.

Q: What does "Feed Through" feature mean?

A: Feed Through indicates the connector allows signal or power to pass through the connector body, enabling daisy-chain or series configurations in ribbon cable applications.
