Substitute Part Grouping Explanation

Substitution eligibility for the M80-6812645 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Position count (26 positions)
• Mating pitch (0.079" / 2.00mm)
• Row configuration (2 rows with 0.079" spacing)
• Mounting method (Surface Mount)
• Termination type (Solder)
• Mating contact finish (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Voltage rating (120V)
• Regulatory compliance (ROHS3 Compliant)

The M80-6812642 meets all substitution criteria as a functionally equivalent part within the same Datamate L-Tek series.

Parameter Comparison

Engineering Selection Recommendations

The M80-6812642 is the direct substitute for the obsolete M80-6812645. Both parts maintain identical electrical and mechanical specifications across all critical mating and mounting parameters. The M80-6812642 carries active product status, ensuring ongoing availability and supply chain support.

The M80-6812642 differs from the main part only in post contact finish specifications: tin plating with increased thickness (157.5µin / 4.00µm) versus gold plating (12.0µin / 0.30µm). These post contact differences do not affect mating interface performance or connector functionality in board-to-board or cable applications.

Both parts maintain ROHS3 compliance and identical regulatory certifications, supporting continued use in automotive, general purpose, and military applications.

Frequently Asked Questions (FAQ)

Q: Can M80-6812642 directly replace M80-6812645 in existing designs?

A: Yes. The M80-6812642 is functionally equivalent across all mating and mounting parameters. Connector pitch, position count, row configuration, mounting type, and operating specifications are identical.

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

A: The M80-6812645 features gold post contacts (12.0µin / 0.30µm thickness), while the M80-6812642 features tin post contacts (157.5µin / 4.00µm thickness). Post contact finish does not affect mating interface performance in standard board-to-board or cable applications.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the M80-6812645 and M80-6812642 are ROHS3 compliant, REACH unaffected, and carry identical material flammability ratings (UL94 V-0).

Q: What packaging differences exist between these parts?

A: The M80-6812645 packaging is not specified in available data. The M80-6812642 is supplied in tube packaging.

Q: Why is the M80-6812645 listed as obsolete?

A: The M80-6812645 has reached end-of-life status. The M80-6812642 remains in active production within the same Datamate L-Tek series and serves as the current equivalent.
