Substitute Part Grouping Explanation

Substitution of the M80-8191205 is based on strict electrical and mechanical compatibility within the Datamate L-Tek series. The following parameters define acceptable substitutes:

Identical pitch spacing: 0.079" (2.00mm) mating pitch and row spacing
Matching position count: 12 positions in 2-row configuration
Compatible connector type: Header or plug configuration within the same series
Equivalent electrical ratings: 2.2A current capacity and 120V voltage rating
Matching mounting and termination: Through-hole solder termination
Identical shrouding: Shrouded 4-wall design
Equivalent environmental specifications: -55°C ~ 125°C operating range

Engineering Selection Recommendations

The M80-7541242 is the direct substitute for the obsolete M80-8191205. Both components maintain identical electrical and mechanical specifications across all critical parameters: 12-position, 2-row configuration with 2.00mm pitch, through-hole solder termination, and equivalent current and voltage ratings.

Key differences are limited to material composition and connector type designation. The M80-7541242 uses Polyphenylene Sulfide (PPS) insulation material instead of polyester, providing enhanced thermal and chemical resistance. The contact post length differs by 0.036" (0.90mm), which may require PCB layout verification for specific applications.

The M80-7541242 holds active product status with current manufacturing support, ROHS3 compliance, and UL94 V-0 flammability rating, making it suitable for direct replacement in new designs and legacy system updates.

Frequently Asked Questions (FAQ)

Q: Can M80-7541242 directly replace M80-8191205 in existing designs?

A: The M80-7541242 is electrically and mechanically compatible with the M80-8191205 across all critical parameters. The primary consideration is the contact post length difference of 0.036" (0.90mm). PCB hole depth and solder pad design should be verified to accommodate the shorter post length of the substitute part.

Q: What is the difference between the connector types listed as "Plug" and "Header"?

A: Both designations refer to male pin connectors within the Datamate L-Tek series. The functional performance and mating characteristics remain equivalent. The terminology difference reflects manufacturer classification within the product line.

Q: Are there packaging differences between these parts?

A: The M80-8191205 packaging is not specified in available documentation. The M80-7541242 is supplied in tube packaging. Packaging format may affect procurement and handling procedures but does not impact electrical or mechanical compatibility.

Q: Why does the insulation material differ between these parts?

A: The M80-7541242 uses Polyphenylene Sulfide (PPS) glass-filled insulation, which provides superior thermal stability and chemical resistance compared to the polyester glass-filled material in the M80-8191205. Both materials meet UL94 V-0 flammability requirements and operate across the identical -55°C ~ 125°C temperature range.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the M80-8191205 and M80-7541242 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What are the mated stacking heights used for?

A: The mated stacking heights (7.23mm, 7.85mm, 10.2mm, 14.61mm) define the vertical distance between mated connector pairs when stacked in multi-level board configurations. Both parts support identical stacking heights.
