TE Connectivity 1-640600-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640600-5 is a 15-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 20 AWG discrete or ribbon cable. This connector features a tin-lead contact finish and free-hanging in-line mounting configuration with locking ramp fastening.

The 1-640600-5 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements for legacy systems utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-640600-5 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for connector type, position count, pitch, row configuration, contact type, termination method, wire gauge compatibility, mounting style, and fastening mechanism.

The following parameters establish substitution eligibility:

• Connector type: Receptacle
• Position count: 15
• Pitch: 0.156" (3.96mm)
• Row count: 1
• Contact type: Female Socket
• Cable termination: IDC
• Wire gauge: 20 AWG
• Wire type: Discrete or Ribbon Cable
• Mounting: Free Hanging (In-Line)
• Fastening: Locking Ramp
• Series: MTA-156
• Contact finish thickness: 80.0µin (2.03µm)

Contact finish composition (tin-lead versus tin) does not preclude substitution when all other parameters remain constant, as both finishes meet the same contact finish thickness specification and are applied to identical base connector geometry.

Parameter Comparison

Engineering Selection Recommendations

The 4-640600-5 is the direct substitute for the obsolete 1-640600-5. Both connectors are manufactured by TE Connectivity and belong to the MTA-156 series. All electrical and mechanical parameters are identical, including connector geometry, contact configuration, termination method, and wire gauge compatibility.

The primary distinction between these parts is product status and regulatory compliance. The 1-640600-5 is obsolete and RoHS non-compliant, while the 4-640600-5 is active and ROHS3 compliant. The contact finish differs (tin-lead versus tin); however, both finishes maintain the same thickness specification of 80.0µin (2.03µm) and are applied to identical connector bodies.

For new designs and ongoing production, the 4-640600-5 is the appropriate selection. For legacy system maintenance where the original tin-lead finish is specifically required, the 1-640600-5 remains available in current inventory (734 pieces). The 4-640600-5 is available in higher inventory quantity (1,014 pieces) and is supplied in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the 4-640600-5 be used as a direct replacement for the 1-640600-5 in existing assemblies?

A: Yes. The 4-640600-5 is mechanically and electrically equivalent to the 1-640600-5. All connector dimensions, contact configurations, termination methods, and wire gauge specifications are identical. Both connectors are compatible with the same mating plugs and cable assemblies.

Q: What is the difference between the tin-lead finish on the 1-640600-5 and the tin finish on the 4-640600-5?

A: Both finishes are applied to the same contact thickness specification of 80.0µin (2.03µm). The contact finish composition differs, but the electrical and mechanical performance characteristics remain equivalent for this connector application.

Q: Why is the 1-640600-5 classified as obsolete?

A: The 1-640600-5 is no longer in active production. The 4-640600-5 is the current active equivalent part from TE Connectivity and is the recommended selection for new applications.

Q: Does the RoHS compliance difference affect substitution compatibility?

A: RoHS compliance status reflects manufacturing and material standards but does not affect the physical or electrical compatibility of the connector. The 4-640600-5 meets ROHS3 compliance requirements, making it suitable for applications with regulatory compliance mandates.

Q: Are both connectors available in the same packaging?

A: The 1-640600-5 packaging specification is not provided. The 4-640600-5 is supplied in bulk packaging. Packaging differences do not affect connector compatibility or performance.

Q: Can discrete wires and ribbon cable both be terminated using IDC on these connectors?

A: Yes. Both the 1-640600-5 and 4-640600-5 support IDC termination for discrete or ribbon cable at 20 AWG wire gauge.

Q: What is the pitch specification, and why is it important for substitution?

A: The pitch is 0.156" (3.96mm), which defines the center-to-center spacing between adjacent contacts. This specification must remain constant for mechanical compatibility with mating connectors and cable assemblies.
