Substitute Part Grouping Explanation

Substitution eligibility for the M80-8430345 is determined by strict equivalence across the following critical parameters:

Connector type, contact type, and gender (Header, Male Pin)
Number of positions and rows (3 positions, 1 row)
Pitch specification (0.079" / 2.00mm mating pitch)
Mounting configuration (Through Hole, Right Angle)
Shrouding design (Shrouded - 4 Wall)
Electrical ratings (2.2A current, 120V voltage)
Operating temperature range (-55°C ~ 125°C)
Material and flammability compliance (PPS Glass Filled, UL94 V-0)
Series compatibility (Datamate L-Tek)

The M80-8430342 qualifies as a direct substitute based on matching all critical parameters. Differences in contact finish specifications and product status do not affect functional interchangeability in the specified application.

Engineering Selection Recommendations

The M80-8430342 is the qualified substitute for the obsolete M80-8430345. Both components maintain identical electrical and mechanical specifications across all critical parameters, including pitch, position count, mounting configuration, and thermal operating range. Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The primary distinction is product status: M80-8430345 is obsolete while M80-8430342 is active and available in production quantities. The M80-8430342 is packaged in tube format and maintains full compatibility with existing designs specified for the M80-8430345.

The contact finish on the post differs between the two parts (gold versus tin), but this does not affect functional interchangeability in solder termination applications. Both finishes are compatible with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can M80-8430342 be used as a direct replacement for M80-8430345?

A: Yes. The M80-8430342 is functionally equivalent across all critical electrical and mechanical parameters. Both components share identical pitch, position count, mounting type, shrouding configuration, and electrical ratings. The substitute is suitable for direct board-level replacement.

Q: What is the difference in contact finish between these parts?

A: The M80-8430345 features gold plating on the post contact, while the M80-8430342 uses tin plating on the post. The mating contact surfaces on both parts are gold-plated. This difference does not affect solder joint reliability or electrical performance in standard PCB assembly applications.

Q: Why is M80-8430345 listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The M80-8430342 is the active production equivalent and is recommended for new designs and ongoing procurement.

Q: Are there packaging differences between these parts?

A: The M80-8430345 packaging is not specified in the available data. The M80-8430342 is supplied in tube packaging. Confirm packaging requirements with your procurement specification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both M80-8430345 and M80-8430342 are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for material flammability. Both maintain identical operating temperature ranges and moisture sensitivity levels.

Q: What is the mating pitch for this connector?

A: Both parts operate at 0.079 inches (2.00mm) mating pitch. This specification is critical for mate-face compatibility with corresponding receptacle connectors in the Datamate L-Tek series.
