Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Connector Type & Contact Configuration: Receptacle, female socket, 50 positions
Pitch & Spacing: 0.079" (2.00mm) mating pitch with 2-row configuration and 0.079" row spacing
Mounting & Termination: Through-hole solder termination with push-pull fastening
Mating Contact Finish: Gold plating on mating surfaces
Operating Temperature Range: Minimum -55°C to 125°C capability
Electrical Performance: Current and voltage ratings must meet or exceed 1A and 125V respectively

All substitute parts listed below satisfy these core requirements. Variations in contact material, post finish, insulation material, and RoHS compliance are noted but do not disqualify substitution eligibility when electrical and mechanical parameters align.

Engineering Selection Recommendations

Primary Recommendation for RoHS3 Compliance: The 3M 150250-6002-RB, TE Connectivity 4-1734506-8 and 9-1734506-8, Harwin M22-7142542, and Samtec MMS series (MMS-125-01-F-DV, MMS-125-01-H-DV, MMS-125-01-L-DV-01, MMS-125-01-L-DV-02) are all ROHS3 compliant active products. These are preferred for new designs requiring regulatory compliance.

Temperature Range Consideration: The Molex 0791070024 operates to 125°C. The Amphenol ICC 63453-350LF, Samtec MMS series, and Mill-Max 833-13-050-10-002000 maintain this full temperature range. The 3M 150250-6002-RB, TE Connectivity AMPMODU variants, and Harwin M22-7142542 operate to 105°C maximum, suitable for applications not requiring the full -55°C to 125°C span.

Current Rating: The original part is rated 1A. Substitute options with higher current ratings (Amphenol ICC 63453-350LF at 2A, Mill-Max 833-13-050-10-002000 at 3A, and Samtec MMS series at 3.9A per contact) provide additional margin for power delivery applications.

Voltage Rating: The original 125V rating is exceeded by all active substitutes. The 3M 150250-6002-RB (500VDC), TE Connectivity variants (250VAC), Harwin M22-7142542 (500VAC), and Amphenol ICC 63453-350LF (200V) all provide adequate voltage isolation.

Non-RoHS Alternatives: The Mill-Max 833-13-050-10-002000 is non-compliant but offers active product status and higher current capacity for legacy system support.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the Molex 0791070024 with any of these substitutes?

A: Yes, all listed parts are mechanically and electrically compatible. They share the same 50-position, 2-row configuration with 0.079" (2.00mm) pitch, through-hole solder termination, and push-pull fastening. Verify your application's specific temperature, voltage, and current requirements against the substitute's ratings.

Q: What is the difference between the Samtec MMS-125-01-L-DV-01 and MMS-125-01-L-DV-02?

A: Both are 50-position receptacles with 49 positions loaded. The primary difference is packaging designation. Both maintain identical electrical and mechanical specifications for substitution purposes.

Q: Why do some substitutes show no voltage rating?

A: The Samtec MMS series and certain other parts do not specify voltage ratings in the provided data. This does not indicate inadequacy; it reflects manufacturer documentation practices. Contact the manufacturer for specific voltage specifications if required for your application.

Q: Which substitute offers the best compliance for new designs?

A: The 3M 150250-6002-RB, TE Connectivity AMPMODU series (4-1734506-8, 9-1734506-8), Harwin M22-7142542, and Samtec MMS series all carry ROHS3 compliance and active product status, making them suitable for modern manufacturing and regulatory requirements.

Q: Are there packaging differences I should consider?

A: Yes. The 3M 150250-6002-RB ships in trays, Amphenol ICC 63453-350LF in tubes, Mill-Max 833-13-050-10-002000 in bulk, Harwin M22-7142542 in bulk, and Samtec MMS variants in tubes or unspecified packaging. Verify packaging compatibility with your procurement and assembly processes.

Q: Can I use these substitutes in automotive applications?

A: The original Molex 0791070024 lists automotive applications. The Amphenol ICC 63453-350LF explicitly supports general purpose, industrial, and medical applications. Verify specific automotive qualification requirements with the substitute manufacturer if automotive certification is mandatory.
