Key Parameters

Substitute Part Grouping Explanation

The M80-8520342 qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Configuration: Both are header connectors with identical male pin contact type, 3-position configuration, and 0.079" (2.00mm) mating pitch
• Mechanical Compatibility: Both feature shrouded 4-wall design, through-hole mounting, and solder termination with matching insulation height of 0.219" (5.56mm)
• Electrical Performance: Both maintain identical current rating (2.2A) and voltage rating (800V), with operating temperature range of -55°C ~ 125°C
• Contact Specifications: Both use phosphor bronze material with gold mating finish (29.5µin / 0.75µm) and matching post length of 0.118" (3.00mm)
• Series Continuity: Both belong to the Datamate L-Tek series, ensuring design consistency

Parameter Comparison

Engineering Selection Recommendations

The M80-8520342 is the direct substitute for the obsolete M80-8050322. Selection of the substitute is justified by:

• Product Status: The M80-8050322 is obsolete, while M80-8520342 is active and currently in production, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: M80-8520342 achieves ROHS3 compliance, whereas the original part is RoHS non-compliant, aligning with current environmental regulations
• Functional Equivalence: All critical electrical and mechanical parameters are identical, including current/voltage ratings, operating temperature range, contact configuration, and mating pitch
• Minor Differences: The substitute features improved insulation material (PPS vs. polyester) and updated fastening mechanism (latch holder vs. friction lock), both representing design enhancements without affecting electrical performance or mechanical fit

Frequently Asked Questions (FAQ)

Q: Can M80-8520342 be used as a direct replacement for M80-8050322 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), position count (3), contact type (male pin), electrical ratings (2.2A / 800V), and mechanical envelope. The substitute is mechanically and electrically compatible.

Q: What is the difference between friction lock and latch holder fastening?

A: Friction lock relies on contact pressure to retain mating connectors, while latch holder uses a mechanical latch mechanism for positive retention. Both are valid fastening methods; the latch holder in M80-8520342 provides enhanced mating security.

Q: Does the insulation material change affect performance?

A: No. Both polyester and polyphenylene sulfide (PPS) are glass-filled materials rated UL94 V-0. PPS offers superior thermal and chemical resistance, representing an improvement over the original polyester formulation.

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

A: M80-8050322 is RoHS non-compliant (contains lead in solder finish), while M80-8520342 is ROHS3 compliant. For new designs or applications subject to environmental regulations, the substitute meets current compliance requirements.

Q: Are there packaging differences between these parts?

A: M80-8050322 packaging is unspecified in available data. M80-8520342 is supplied in tube packaging. Confirm packaging requirements with procurement specifications.

Q: Do both parts have the same contact finish specifications?

A: Mating contact finish is identical (gold, 29.5µin / 0.75µm). Post finish differs: M80-8050322 uses tin-lead, while M80-8520342 uses tin only, consistent with RoHS compliance.
