Substitute Part Grouping Explanation

Substitution eligibility for the M80-8631442 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Both substitute parts (M80-8531442 and M80-8541442) are headers with male pin contacts, maintaining the same mating interface as the original plug configuration within the Datamate L-Tek series ecosystem.
Position Count & Pitch: All parts maintain 14 positions in 2 rows with identical 2.00mm mating pitch and row spacing.
Electrical Ratings: Current rating (2.2A) and voltage rating (800V) are identical across all three parts.
Thermal Range: Operating temperature range of -55°C to 125°C is consistent.
Mechanical Mounting: All parts feature through-hole solder termination with shrouded 4-wall design.
Compliance: All parts are ROHS3 compliant with identical material flammability rating (UL94 V-0).

The primary distinction between substitute parts lies in fastening mechanism (Friction Lock vs. Latch Lock vs. Latch Holder) and insulation material composition (Polyamide PA46 vs. Polyphenylene Sulfide PPS Glass Filled), which do not affect electrical or thermal compatibility within the specified parameter set.

Engineering Selection Recommendations

M80-8531442 is the primary recommended substitute. This part maintains active product status with the highest inventory availability (2655 units), ensuring supply chain continuity. It is ROHS3 compliant and carries identical electrical and thermal specifications. The upgrade to polyphenylene sulfide insulation material provides enhanced chemical resistance compared to the original polyamide formulation.

M80-8541442 is an alternative substitute with active product status and adequate inventory (795 units). This part is functionally equivalent within the specified parameter set and is also ROHS3 compliant with identical electrical ratings and operating temperature range.

Both substitute parts are suitable for direct replacement in applications where the original M80-8631442 was specified, provided that mechanical fastening mechanism compatibility (Latch Lock or Latch Holder versus Friction Lock) is verified for the mating connector interface in the target application.

Frequently Asked Questions (FAQ)

Q: Can M80-8531442 or M80-8541442 be used as direct replacements for M80-8631442?

A: Yes. Both substitute parts maintain identical electrical ratings (2.2A, 800V), thermal operating range (-55°C to 125°C), position count (14 positions, 2 rows), mating pitch (2.00mm), and mechanical mounting configuration (through-hole, shrouded 4-wall). The primary difference is the fastening mechanism; verify compatibility with the mating connector interface.

Q: What is the difference between the two substitute parts?

A: M80-8531442 and M80-8541442 differ only in fastening type (Latch Lock versus Latch Holder). Both use polyphenylene sulfide glass-filled insulation material, whereas the original part uses polyamide. Electrical and thermal performance are equivalent.

Q: Why is the original M80-8631442 obsolete?

A: The product status reflects Harwin Inc.'s discontinuation of this specific configuration. Active alternatives with superior material properties and enhanced fastening mechanisms are available.

Q: Are there packaging differences between the original and substitute parts?

A: The original M80-8631442 packaging is not specified in the technical data. Both substitute parts are supplied in tube packaging, which is standard for this connector category.

Q: Do all three parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
