Engineering Selection Recommendations

The M80-6810842 is the direct substitute for the obsolete M80-6810801. Both connectors are mechanically and electrically identical across all critical parameters, ensuring pin-for-pin compatibility and functional interchangeability in existing designs.

A key distinction exists in regulatory compliance: the M80-6810842 is ROHS3 compliant, whereas the M80-6810801 is RoHS non-compliant. For applications subject to RoHS directives or requiring compliance documentation, the M80-6810842 is the appropriate selection. Additionally, the M80-6810842 is currently in active production status with higher inventory availability, supporting supply chain continuity.

The contact finish on the post differs between the two parts: the M80-6810801 uses tin-lead plating while the M80-6810842 uses tin plating. This difference does not affect electrical performance or mechanical compatibility in standard solder reflow processes.

Frequently Asked Questions (FAQ)

Q: Are M80-6810801 and M80-6810842 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.079"/2.00mm), row spacing, mounting type (surface mount), insulation height, and mated stacking heights. They are direct mechanical substitutes.

Q: What is the difference in contact post plating?

A: The M80-6810801 features tin-lead plating on the post, while the M80-6810842 uses tin plating. Both are compatible with standard solder reflow processes and do not affect electrical performance or mechanical fit.

Q: Why is RoHS compliance different between these parts?

A: The M80-6810801 is classified as RoHS non-compliant, while the M80-6810842 is ROHS3 compliant. This reflects manufacturing process updates and regulatory alignment. For applications requiring RoHS compliance documentation, the M80-6810842 must be selected.

Q: Can I use M80-6810842 in place of M80-6810801 in existing designs?

A: Yes. The M80-6810842 is a direct functional and mechanical equivalent. No design modifications are required for substitution.

Q: What packaging is available for the substitute part?

A: The M80-6810842 is supplied in tube packaging, whereas the M80-6810801 packaging specification is not provided. Confirm packaging requirements with procurement specifications.

Q: Are both parts rated for the same operating temperature range?

A: Yes. Both connectors operate across -55°C to 125°C and maintain UL94 V-0 flammability rating across this range.
