Engineering Selection Recommendations

Both M80-5301022 and M80-5301042 are active production parts from Harwin Inc. within the Datamate J-Tek series and are electrically and mechanically interchangeable based on all critical connector parameters.

Selection Criteria:

M80-5301022 is appropriate for applications where RoHS non-compliance is acceptable or where legacy designs specifically require Tin-Lead post finish.
M80-5301042 is the preferred selection for new designs, applications requiring RoHS3 compliance, or when higher inventory availability is advantageous. The Tin post finish on M80-5301042 provides equivalent electrical performance and solderability compared to the Tin-Lead finish of M80-5301022.

Both parts carry identical electrical ratings (2.2A, 800V), operating temperature range (-55°C ~ 125°C), and mechanical specifications. The choice between them is determined by regulatory compliance requirements and post-finish specifications rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Are M80-5301022 and M80-5301042 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 10-position, 2-row configuration, 0.079" (2.00mm) pitch, through-hole right-angle mounting, and shrouded 4-wall design. PCB footprints and mating interfaces are identical.

Q: What is the difference between Tin-Lead and Tin post finishes?

A: M80-5301022 uses Tin-Lead post finish while M80-5301042 uses Tin post finish. Both finishes provide equivalent solderability and electrical conductivity. The primary distinction is regulatory: Tin-Lead finish is associated with RoHS non-compliance, while Tin finish supports ROHS3 compliance.

Q: Can I use M80-5301042 as a direct replacement for M80-5301022 in existing designs?

A: Yes. M80-5301042 is a direct substitute with identical electrical and mechanical performance. The change from Tin-Lead to Tin post finish does not affect connector function, mating characteristics, or electrical ratings. Designs using M80-5301022 can transition to M80-5301042 without modification.

Q: Why does M80-5301042 have higher inventory than M80-5301022?

A: M80-5301042 is ROHS3 compliant, making it the preferred part for current production and new designs. Higher inventory reflects market demand for RoHS-compliant components.

Q: Are the electrical ratings identical between these two parts?

A: Yes. Both parts are rated for 2.2A current and 800V voltage with identical operating temperature range (-55°C ~ 125°C) and contact material specifications.

Q: What certifications apply to both parts?

A: Both M80-5301022 and M80-5301042 carry UL94 V-0 material flammability rating and are part of the Datamate J-Tek series. M80-5301042 additionally carries ROHS3 compliance certification.
