Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M80-7911422 is determined by the following critical parameters:

• Connector Type & Contact Type: Must be Header with Male Pin configuration
• Position Count & Row Configuration: Must maintain 14 positions in 2-row arrangement
• Pitch Specifications: Mating pitch and row spacing must both be 0.079" (2.00mm)
• Mounting & Termination: Through-hole, right-angle mounting with solder termination required
• Shrouding Design: Shrouded 4-wall configuration mandatory
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Compliance Standards: RoHS3 compliance and UL94 V-0 flammability rating required

The M80-7711442 qualifies as a direct substitute based on matching all critical parameters. Differences in fastening type (Latch Lock vs. Latch Holder), insulation material composition, contact finish on posts, current rating, and voltage rating do not prevent functional substitution when the application requirements align with the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The M80-7711442 is the active equivalent for the obsolete M80-7911422. Both connectors maintain identical mechanical and electrical interface specifications, ensuring PCB-level compatibility. The substitute part carries Active product status, providing long-term availability and supply chain continuity.

Selection of M80-7711442 over M80-7911422 is supported by:

• Product Status: M80-7711442 is Active, ensuring ongoing manufacturing and procurement support
• Compliance Alignment: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification
• Interface Compatibility: Identical pitch, position count, row configuration, and mounting geometry guarantee mechanical interchangeability
• Thermal Performance: Both parts support the full -55°C ~ 125°C operating temperature range

Applications requiring the original M80-7911422 specifications should transition to M80-7711442 for new designs and production continuity. The substitute part's lower current rating (2.2A per contact vs. 2.6A) and reduced voltage rating (120V vs. 800V) must be evaluated against specific application requirements. The change in insulation material from Polyamide to Polyphenylene Sulfide (glass-filled) and post contact finish from Tin-Lead to Tin represents material improvements in thermal and environmental performance.

Frequently Asked Questions (FAQ)

Q: Are M80-7911422 and M80-7711442 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), position count (14), row configuration (2 rows), mounting type (through-hole, right-angle), and shrouding design (4-wall). PCB footprints and mating interface dimensions are identical.

Q: What is the primary reason for substitution?

A: The M80-7911422 carries Obsolete product status. The M80-7711442 is the active equivalent from Harwin Inc., ensuring continued availability and supply chain support.

Q: Do the differences in fastening type affect compatibility?

A: Fastening type differences (Latch Holder vs. Latch Lock) do not affect electrical or mechanical interface compatibility. Both designs provide secure mating retention within the Datamate L-Tek series.

Q: How do the current and voltage ratings differ?

A: M80-7911422 is rated 2.6A at 800V, while M80-7711442 is rated 2.2A per contact at 120V. Applications must confirm that the substitute part's electrical ratings meet circuit requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both M80-7911422 and M80-7711442 are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What changed in the insulation material?

A: M80-7911422 uses Polyamide (PA46) Nylon 4/6, while M80-7711442 uses Polyphenylene Sulfide (PPS) glass-filled material. PPS offers improved thermal and chemical resistance.

Q: Is the contact finish change from Tin-Lead to Tin significant?

A: The post contact finish changed from Tin-Lead to Tin, reflecting industry transition away from lead-based finishes. Mating contact finish remains Gold on both parts. This change does not affect electrical performance for standard applications.
