Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 1-640602-1 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (11)
• Pitch spacing (0.156")
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Fastening type (Locking Ramp)

Electrical Compatibility Parameters:

• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge (24 AWG)
• Contact finish thickness (80.0µin)

Series Designation:

• MTA-156 series membership

The substitute part 4-640602-1 maintains identical mechanical and electrical specifications across all critical parameters. The primary distinction between the main part and its substitute is the contact finish composition and product status classification.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs:

The 4-640602-1 is the appropriate selection for new applications and ongoing production. This part maintains active product status with TE Connectivity and carries RoHS compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

For Legacy System Support:

The 1-640602-1 remains suitable for direct replacement in existing installations where the connector is already deployed. The obsolete status reflects market discontinuation rather than functional inadequacy. The 4-640602-1 provides functional equivalence for maintenance and repair scenarios requiring component replacement.

Contact Finish Consideration:

The 1-640602-1 features tin-lead contact finish, while the 4-640602-1 uses tin finish. Both maintain identical contact finish thickness (80.0µin). The transition from tin-lead to tin reflects industry-wide RoHS compliance adoption. Mechanical and electrical performance characteristics remain equivalent across both contact finish specifications.

Regulatory Compliance:

The 4-640602-1 satisfies RoHS compliance requirements applicable to current manufacturing standards. Organizations subject to RoHS regulations should transition to the 4-640602-1 for new procurements and production planning.

Frequently Asked Questions (FAQ)

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

A: Yes. The 4-640602-1 maintains identical mechanical and electrical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, fastening type, cable termination method, and wire gauge.
