Key Parameters

Substitute Part Grouping Explanation

The M80-4024242 qualifies as a direct substitute for the M80-4024201P based on matching electrical and mechanical parameters. Substitution compatibility is determined by the following critical parameters:

• Connector type (Receptacle) and contact type (Female Socket) match exactly
• Position count (42) and pitch configuration (0.079" / 2.00mm) are identical
• Row configuration (2 rows with 0.079" spacing) is identical
• Mounting type (Surface Mount) and termination method (Solder) are identical
• Fastening mechanism (Screw Lock) is identical
• Contact material (Beryllium Copper) and mating contact finish (Gold) are identical
• Operating temperature range (-55°C ~ 125°C) is identical
• Voltage rating (120V) is identical
• Flammability rating (UL94 V-0) is identical
• Insulation material (Polyphenylene Sulfide, Glass Filled) is identical

The M80-4024242 represents the active production equivalent within the same Datamate J-Tek series, with RoHS3 compliance and current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The M80-4024242 is the recommended substitute for the obsolete M80-4024201P. Both connectors share identical electrical and mechanical specifications across all critical parameters, ensuring direct functional compatibility in board-to-board and cable applications.

The M80-4024242 carries active product status with current manufacturing support and RoHS3 compliance, providing supply chain continuity and regulatory alignment for new designs and production environments. The connector maintains full compatibility with existing mating interfaces and PCB layouts designed for the M80-4024201P.

The minor difference in post contact finish (Tin versus Tin-Lead on the original part) does not affect electrical performance or mechanical compatibility. Both finishes meet the same solderability and reliability standards for surface mount termination.

Frequently Asked Questions (FAQ)

Q: Can the M80-4024242 be used as a direct replacement for the M80-4024201P in existing designs?

A: Yes. The M80-4024242 is electrically and mechanically identical to the M80-4024201P across all critical parameters including pitch, position count, row configuration, contact material, and operating specifications. No design modifications are required.

Q: What is the significance of the product status change from Obsolete to Active?

A: The M80-4024242 is in active production with current manufacturing support and inventory availability. This ensures reliable supply for new production runs and ongoing system support without the constraints associated with obsolete components.

Q: Are there any compliance or certification differences between these parts?

A: Both connectors carry identical compliance certifications including UL94 V-0 flammability rating, REACH Unaffected status, and EAR99 export classification. The M80-4024242 includes RoHS3 compliance documentation.

Q: What is the difference in mated stacking heights between the two parts?

A: The M80-4024201P specifies stacking heights of 7.7mm and 7.98mm, while the M80-4024242 specifies 7.7mm and 7.95mm. This minor variation (0.03mm) is within typical manufacturing tolerances and does not affect mechanical compatibility or performance in standard applications.

Q: Are the contact finishes compatible for mating purposes?

A: Yes. Both parts feature gold-plated mating contacts with identical thickness specifications (12.0µin / 0.30µm). The difference in post contact finish (Tin-Lead versus Tin) does not affect mating performance or electrical characteristics.

Q: What applications are these connectors suitable for?

A: Both connectors are rated for automotive, general purpose, and military applications with an operating temperature range of -55°C to 125°C and 120V voltage rating, supporting diverse industrial and defense system requirements.
