Engineering Selection Recommendations

The 4-640600-2 serves as the direct substitute for the obsolete 1-640600-2. Both connectors are manufactured by TE Connectivity and belong to the MTA-156 series with identical mechanical and electrical specifications.

Product Status Consideration: The 1-640600-2 is classified as obsolete, while the 4-640600-2 maintains active product status. For new designs, maintenance programs, and long-term supply chain planning, the 4-640600-2 is the appropriate selection.

Compliance Distinction: The 1-640600-2 features a tin-lead contact finish and is RoHS non-compliant. The 4-640600-2 utilizes a tin contact finish and is RoHS compliant. Both connectors maintain identical contact finish thickness of 80.0µin (2.03µm) and moisture sensitivity level of 1 (Unlimited).

Functional Equivalence: The substitution is direct and complete. The 4-640600-2 maintains full compatibility with existing mating connectors, cable assemblies, and PCB layouts designed for the 1-640600-2. No design modifications or re-qualification are required.

Frequently Asked Questions (FAQ)

Q: Are the 1-640600-2 and 4-640600-2 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 12-position configuration, 0.156" pitch, single-row layout, free-hanging in-line mounting, and locking ramp fastening. They are fully interchangeable in existing assemblies.

Q: What is the difference between the tin-lead finish on the 1-640600-2 and the tin finish on the 4-640600-2?

A: The 1-640600-2 uses a tin-lead contact finish and is RoHS non-compliant. The 4-640600-2 uses a tin contact finish and is RoHS compliant. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The 4-640600-2 is suitable for applications requiring RoHS compliance.

Q: Can the 4-640600-2 be used as a direct replacement in legacy systems?

A: Yes. The 4-640600-2 is a direct substitute for the 1-640600-2. It maintains identical electrical and mechanical specifications, including IDC termination capability, 20 AWG wire gauge support, and feed-through functionality. No system modifications are required.

Q: Why is the 1-640600-2 classified as obsolete?

A: The 1-640600-2 is obsolete due to its RoHS non-compliant tin-lead contact finish. The 4-640600-2 represents the current active equivalent with RoHS-compliant tin finish.

Q: Are there any packaging differences between these connectors?

A: The 1-640600-2 packaging information is not specified in the available data. The 4-640600-2 is supplied in bulk packaging. Contact the manufacturer for specific packaging requirements for the 1-640600-2.
