Identical number of positions (6) and row configuration (2 rows)
Identical mating pitch and row spacing (0.079" / 2.00mm)
Identical mounting style (Through Hole, Right Angle)
Identical shrouding configuration (Shrouded - 4 Wall)
Identical electrical ratings (2.2A current, 120V voltage)
Identical operating temperature range (-55°C ~ 125°C)
Identical contact finish material and specification (Gold, 29.5µin / 0.75µm)
Identical base contact material (Phosphor Bronze)
Identical termination method (Solder)
Identical flammability rating (UL94 V-0)

Key Difference - Product Status: The M80-8410645 is an active product, whereas the M80-8390645 is obsolete. This substitution addresses supply chain continuity while maintaining full electrical and mechanical compatibility.

Engineering Selection Recommendations

The M80-8410645 is the direct substitute for the obsolete M80-8390645. Both components maintain identical electrical and mechanical specifications across all critical parameters: connector configuration, contact ratings, operating temperature range, and compliance certifications (ROHS3, REACH Unaffected, UL94 V-0).

The M80-8410645 is currently in active production status with confirmed inventory availability, ensuring supply chain continuity. The substitute maintains the same Datamate L-Tek series designation and is manufactured by the same supplier, Harwin Inc.

Minor variations exist in fastening mechanism (Latch Holder versus Friction Lock) and insulation material composition (PPS glass-filled versus Polyamide), along with a marginal increase in insulation height (0.235" versus 0.220"). These differences do not affect electrical performance or mechanical compatibility in standard board-to-board or cable applications.

Frequently Asked Questions (FAQ)

Q: Can M80-8410645 be used as a direct replacement for M80-8390645?

A: Yes. The M80-8410645 is electrically and mechanically compatible with the M80-8390645. Both components share identical connector type, pitch, position count, contact ratings, and operating specifications. The substitute is suitable for direct board-level replacement.

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

A: Both fastening mechanisms provide secure mating between header and connector. Friction Lock relies on contact pressure, while Latch Holder uses a mechanical locking feature. The choice depends on application requirements for mating force and unmating cycles. Consult application documentation for specific fastening requirements.

Q: Are there packaging differences between these parts?

A: The M80-8390645 packaging is not specified in available data. The M80-8410645 is supplied in Tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do the insulation material differences affect compatibility?

A: No. Both Polyamide (PA46) and Polyphenylene Sulfide (PPS) glass-filled materials meet the same UL94 V-0 flammability rating and operating temperature range. Material selection does not impact electrical or mechanical performance in standard applications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both M80-8390645 and M80-8410645 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
