Key Parameters

Substitute Part Grouping Explanation

Substitution for the M80-8412645 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (26 positions, 2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Mounting style and orientation (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Latch Holder)
• Contact material and shape (Phosphor Bronze, Circular)
• Insulation material (Polyphenylene Sulfide, Glass Filled)
• Electrical ratings (2.2A, 120V)
• Environmental compliance (UL94 V-0, ROHS3, REACH Unaffected)

The M80-8412642 qualifies as a direct substitute based on identical values across all these parameters. The primary difference is product status (Active vs. Obsolete) and contact finish specifications on the post termination.

Parameter Comparison

Engineering Selection Recommendations

The M80-8412642 is the direct substitute for the obsolete M80-8412645. Both components are manufactured by Harwin Inc. within the Datamate L-Tek series and maintain identical electrical, mechanical, and environmental specifications.

The M80-8412642 carries Active product status, ensuring ongoing availability and manufacturer support. Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements, with REACH Unaffected status.

The only material difference between the two parts is the contact finish on the post termination: the M80-8412645 uses gold finish, while the M80-8412642 uses tin finish. This difference does not affect functional compatibility, as both finishes provide adequate solder joint reliability and electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can M80-8412642 be used as a direct replacement for M80-8412645?

A: Yes. The M80-8412642 is functionally equivalent across all critical parameters: connector type, position count, pitch, mounting style, electrical ratings, and environmental compliance. The parts are mechanically and electrically interchangeable.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The M80-8412645 is obsolete and no longer manufactured or supported by Harwin Inc. The M80-8412642 is an active product with ongoing availability. For new designs or production continuity, the M80-8412642 should be specified.

Q: How does the contact finish difference (Gold vs. Tin) affect compatibility?

A: Both gold and tin finishes on solder posts provide adequate electrical conductivity and solder joint reliability. The contact finish difference does not impact functional performance within the specified operating temperature range (-55°C ~ 125°C) and electrical ratings (2.2A, 120V).

Q: Are there packaging differences between these parts?

A: The M80-8412642 is supplied in Tube packaging. Packaging format does not affect component functionality or electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both M80-8412645 and M80-8412642 are ROHS3 Compliant, REACH Unaffected, and carry UL94 V-0 material flammability rating.
