Key Parameters

Substitute Part Grouping Explanation

The M80-8430342 qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Both parts are Datamate L-Tek series connectors with male pin contacts, 3 positions, and 0.079" (2.00mm) pitch
• Mechanical Interface: Identical shrouding (4 wall), through-hole right-angle mounting, and insulation height (0.156" / 3.96mm)
• Electrical Ratings: Matching current (2.2A) and voltage (120V) ratings
• Operating Environment: Identical temperature range (-55°C ~ 125°C) and moisture sensitivity level (MSL 1)
• Contact Material & Finish: Both use phosphor bronze with gold mating finish (29.5µin / 0.75µm) and tin-based post finish

The primary differences are connector type designation (Plug vs. Header), insulation material (PBT vs. PPS), fastening mechanism (Friction Lock vs. Latch Holder), and product status (Obsolete vs. Active).

Parameter Comparison

Engineering Selection Recommendations

The M80-8430342 is the designated manufacturer substitute for the obsolete M80-8040322. Selection of the M80-8430342 is supported by the following factors:

• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The M80-8430342 is ROHS3 compliant, whereas the original part is RoHS non-compliant, meeting current environmental regulations
• Electrical & Mechanical Compatibility: All critical electrical ratings, mechanical dimensions, and contact specifications are identical
• Material Upgrade: The PPS insulation material in the substitute provides equivalent or superior performance characteristics compared to the PBT material in the original part
• Lead-Free Transition: The tin post finish (versus tin-lead) aligns with modern manufacturing standards

Frequently Asked Questions (FAQ)

Q: Can M80-8430342 directly replace M80-8040322 in existing designs?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), position count (3), shrouding configuration (4 wall), electrical ratings (2.2A / 120V), and operating temperature range (-55°C ~ 125°C). The mechanical interface and contact specifications are functionally equivalent.

Q: What is the difference between "Plug" and "Header" connector types in this comparison?

A: The M80-8040322 is designated as a Plug, while the M80-8430342 is designated as a Header. Both are male pin connectors within the Datamate L-Tek series designed for board-to-board or cable applications. The functional mating interface remains compatible.

Q: Does the insulation material change affect performance?

A: The M80-8430342 uses polyphenylene sulfide (PPS) glass-filled insulation, while the M80-8040322 uses polybutylene terephthalate (PBT) glass-filled insulation. Both materials meet UL94 V-0 flammability ratings and operate across the identical temperature range (-55°C ~ 125°C). PPS provides equivalent electrical and mechanical performance for this application.

Q: What is the significance of the RoHS compliance difference?

A: The M80-8040322 is RoHS non-compliant, while the M80-8430342 is ROHS3 compliant. For new designs or applications subject to environmental regulations, the M80-8430342 is the appropriate selection.

Q: Are there packaging differences between these parts?

A: The M80-8040322 packaging is not specified. The M80-8430342 is supplied in tube packaging. Confirm packaging requirements for your procurement process.

Q: What is the difference between Friction Lock and Latch Holder fastening?

A: The M80-8040322 uses friction lock fastening, while the M80-8430342 uses latch holder fastening. Both mechanisms provide secure mating within the Datamate L-Tek connector system. Verify mating connector compatibility with your specific application.
