M80-4C12642S1 Equivalent & Substitute Parts

Part Overview

The M80-4C12642S1 is a 26-position rectangular receptacle connector from Harwin Inc.'s Datamate S-Tek series, designed for discrete wire crimp termination with 24-28 AWG wire gauges. This connector features a 2-row configuration with 0.079" (2.00mm) pitch and row spacing, gold-plated contacts, and jackscrew fastening with shielding. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

No substitute parts are currently available in the provided database. Functional equivalents for the M80-4C12642S1 must meet the following critical parameters for direct substitution:

• 26-position rectangular receptacle connector
• Female socket contact type
• 2-row configuration with 0.079" (2.00mm) pitch and row spacing
• Crimp termination for 24-28 AWG discrete wire
• Jackscrew fastening with shielding
• Gold contact finish
• Free hanging (in-line) mounting

Substitute candidates must maintain identical electrical and mechanical specifications across all listed parameters to ensure compatibility with existing mating connectors and cable assemblies.

Engineering Selection Recommendations

The M80-4C12642S1 is classified as an obsolete product. When direct replacements are unavailable, engineering teams must evaluate alternative rectangular connector solutions from active manufacturers that maintain the same 26-position, 2-row, 2.00mm pitch configuration with crimp termination capability. Any alternative must be validated for mechanical fit with existing mating plugs and electrical performance under the application's operating conditions. Compliance with ROHS3 and REACH requirements should be verified for new alternatives to maintain regulatory alignment with the original design.

Frequently Asked Questions (FAQ)

Q: What makes a connector a valid substitute for the M80-4C12642S1?

A: A valid substitute must be a 26-position rectangular receptacle with female sockets, 2-row configuration, 0.079" (2.00mm) pitch and row spacing, crimp termination for 24-28 AWG wire, jackscrew fastening, shielding, and gold-plated contacts.

Q: Why is the M80-4C12642S1 difficult to replace?

A: The product is obsolete, and the specific combination of 26 positions, 2-row layout, 2.00mm pitch, and crimp termination is not universally available across all manufacturers. Substitutes must match these exact mechanical and electrical parameters.

Q: Can I use a connector with a different pitch or row spacing?

A: No. The 0.079" (2.00mm) pitch and row spacing are critical for mechanical compatibility with mating plugs. Deviations will result in misalignment and connection failure.

Q: Are there any compliance considerations when selecting a substitute?

A: Yes. Any substitute should maintain ROHS3 compliance and REACH unaffected status to align with the original design's regulatory requirements.

Q: What if no exact substitute is available?

A: Engineering teams must conduct a full compatibility assessment with alternative rectangular connector families, including mechanical fit validation, electrical performance testing, and regulatory compliance verification before implementation.
