Substitute Part Grouping Explanation

The M80-8503442 qualifies as a direct substitute for the M80-8913401 based on the following critical parameters that determine functional interchangeability:

Identical connector type (receptacle), contact type (female socket), and number of positions (34)
Matching pitch and row spacing (0.079" / 2.00mm)
Identical mounting method (through hole) and termination type (solder)
Matching contact finish at mating surface (gold plating)
Identical operating temperature range (-55°C ~ 125°C)
Equivalent flammability rating (UL94 V-0)
Same series designation (Datamate L-Tek)

The M80-8503442 is an active product with current manufacturing status, providing continuity for applications previously using the obsolete M80-8913401.

Engineering Selection Recommendations

The M80-8503442 is the direct substitute for the obsolete M80-8913401. Both connectors share identical mechanical and electrical specifications across all critical mating and mounting parameters. The substitute part offers the following advantages:

Active product status ensures ongoing availability and manufacturing support
ROHS3 compliance versus non-compliance of the original part, meeting current regulatory requirements
Higher voltage rating (800V versus 120V) provides enhanced electrical capability for demanding applications
Improved post contact finish (Tin versus Tin-Lead) aligns with modern manufacturing standards

The primary design consideration is the contact length difference: the substitute features a 0.118" (3.00mm) post length compared to the original 0.051" (1.30mm). This difference must be evaluated against PCB hole depth and mating component specifications to ensure mechanical compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Are M80-8913401 and M80-8503442 mechanically interchangeable?

A: Yes, both connectors are mechanically interchangeable for board-to-board or cable applications. They share identical pitch (0.079"), row spacing (0.079"), number of positions (34), mounting type (through hole), and mated stacking heights (7.23mm, 7.85mm). The contact post length differs (0.051" versus 0.118"), which must be verified against PCB hole depth specifications.

Q: What is the primary reason for substitution?

A: The M80-8913401 is obsolete. The M80-8503442 is an active product from the same manufacturer and series, providing design continuity and component availability.

Q: Are there electrical differences between these parts?

A: Both connectors operate across the identical temperature range (-55°C ~ 125°C) and feature matching contact materials (beryllium copper) and mating contact finishes (gold). The substitute part has a higher voltage rating (800V versus 120V). Both meet UL94 V-0 flammability requirements.

Q: What is the packaging difference?

A: The M80-8913401 packaging is not specified in available documentation. The M80-8503442 is supplied in tube packaging.

Q: Does the substitute meet current compliance standards?

A: The M80-8503442 is ROHS3 compliant, whereas the M80-8913401 is RoHS non-compliant. Both parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: What should be verified before implementing the substitute?

A: Verify PCB hole depth compatibility with the longer contact post (0.118" versus 0.051"). Confirm that the higher voltage rating (800V) is appropriate for the application. Validate that ROHS3 compliance meets design and regulatory requirements.
