Key Parameters

Substitute Part Grouping Explanation

Substitution of the M80-4125001P is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle) and contact type (Female Socket)
• Position count (50 positions) and pitch configuration (0.079" mating pitch, 2-row layout with 0.079" row spacing)
• Mounting method (Surface Mount) and termination type (Solder)
• Mating contact finish (Gold plating)
• Operating temperature range (-55°C ~ 125°C)
• Voltage rating (120V)
• Insulation material (Polyphenylene Sulfide, Glass Filled)
• Contact material (Beryllium Copper)
• Flammability rating (UL94 V-0)

The M80-4125042 meets all these criteria as a direct substitute within the Datamate J-Tek series.

Parameter Comparison

Engineering Selection Recommendations

The M80-4125042 is the direct substitute for the obsolete M80-4125001P. Both connectors share identical electrical and mechanical specifications across all critical parameters, including pitch, position count, contact materials, and operating temperature range.

The M80-4125042 carries active product status, ensuring ongoing availability and supply chain support. This connector is ROHS3 compliant, providing regulatory advantage for new designs and manufacturing processes.

The post contact finish differs between the two parts: M80-4125001P uses tin-lead plating while M80-4125042 uses tin plating. Both finishes maintain equivalent contact finish thickness (137.8µin / 4.60µm) and are suitable for solder termination. The mated stacking height variance (7.98mm versus 7.95mm) is negligible for board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can M80-4125042 directly replace M80-4125001P in existing designs?

A: Yes. Both connectors are identical in connector type, position count, pitch, mounting method, contact materials, and operating specifications. The M80-4125042 is the active production equivalent.

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

A: M80-4125001P uses tin-lead plating while M80-4125042 uses tin plating. Both maintain the same thickness (137.8µin / 4.60µm) and are compatible with standard solder termination processes.

Q: Are there packaging differences between M80-4125001P and M80-4125042?

A: M80-4125001P packaging is not specified in available data. M80-4125042 is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the mated stacking height difference affect compatibility?

A: The stacking height variance (7.98mm versus 7.95mm, a 0.03mm difference) is within typical manufacturing tolerances and does not affect board-to-board mating compatibility.

Q: Are both connectors suitable for automotive and military applications?

A: Yes. Both M80-4125001P and M80-4125042 are rated for automotive, general purpose, and military applications with UL94 V-0 flammability rating and REACH compliance.

Q: What is the MSL rating for these connectors?

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
