Molex 0791070011 Equivalent & Substitute Parts

Part Overview

The Molex 0791070011 is a 24-position receptacle connector with 0.079" (2.00mm) pitch, designed for through-hole PCB mounting with gold-plated mating contacts. This connector belongs to the Milli-Grid 79107 series and is classified as obsolete. Due to its obsolete status and limited ongoing availability, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production support.

Engineering Selection Recommendations

Primary Substitute: 3M 150224-6002-RB

The 3M 150224-6002-RB is the closest functional equivalent to the Molex 0791070011. It maintains identical mechanical and electrical specifications with the exception of operating temperature range (-55°C ~ 105°C versus -55°C ~ 125°C). This part is active in production, ROHS3 compliant, and available in tray packaging. Selection of this part is appropriate for applications where the upper temperature limit of 105°C is acceptable.

Secondary Substitutes: Samtec MMS Series

The Samtec MMS-112 series provides multiple configuration options for 24-position 0.079" pitch receptacle connectors. All MMS variants are active products with ROHS3 compliance. Key differences within the MMS series include:

MMS-112-01-F-DV: Full 24-position loading, tin post finish, tube packaging
MMS-112-01-H-DV: Full 24-position loading, gold post finish, higher contact finish thickness
MMS-112-01-S-DV: Full 24-position loading, tin post finish, tube packaging, 30.0µin mating contact finish
MMS-112-01-LM-DV: Full 24-position loading, tin post finish, tube packaging
MMS-112-01-L-DV variants (01, 09, 12, 20): 23-position loading, tin post finish

All Samtec MMS variants support the full -55°C ~ 125°C operating temperature range and provide 3.9A per contact current rating, exceeding the original 1A specification. These parts use liquid crystal polymer (LCP) insulation material, offering improved dimensional stability compared to the original thermoplastic glass-filled material.

Compliance Considerations:

The original Molex 0791070011 is RoHS non-compliant. All recommended substitutes (3M 150224-6002-RB and Samtec MMS series) are ROHS3 compliant, making them suitable for applications subject to RoHS regulations. Both manufacturers maintain REACH unaffected status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the 3M 150224-6002-RB be used as a direct replacement for the Molex 0791070011?

A: Yes, the 3M 150224-6002-RB is mechanically and electrically compatible. The primary consideration is the operating temperature range: the 3M part is rated to 105°C maximum versus 125°C for the original. If your application operates within -55°C to 105°C, this part is a direct substitute.

Q: What is the difference between Samtec MMS-112-01-F-DV and MMS-112-01-S-DV?

A: Both parts are functionally equivalent 24-position receptacles with identical pitch, mounting, and fastening specifications. The primary difference is mating contact finish thickness: MMS-112-01-F-DV has 3.00µin (0.076µm) while MMS-112-01-S-DV has 30.0µin (0.76µm). Both meet the gold plating requirement. Selection depends on your contact finish thickness specification.

Q: Why do some Samtec MMS variants show 23 positions loaded instead of 24?

A: The MMS-112-01-L-DV series (variants 01, 09, 12, 20) are manufactured with 23 positions loaded by design. These parts maintain the same 24-position connector body but have one position without a contact. Use these variants only if your application requires 23-position connectivity.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 3M 150224-6002-RB and all Samtec MMS-112 variants are ROHS3 compliant. The original Molex 0791070011 is RoHS non-compliant. If your application requires RoHS compliance, any of the recommended substitutes will satisfy this requirement.

Q: What is the difference in insulation material between the original and substitutes?

A: The Molex 0791070011 uses thermoplastic glass-filled insulation. The 3M 150224-6002-RB uses thermoplastic insulation. The Samtec MMS series uses liquid crystal polymer (LCP) insulation. LCP provides superior dimensional stability and temperature performance. All three materials are compatible with the specified operating temperature ranges of their respective parts.

Q: Can I use Samtec MMS parts rated for 3.9A per contact in place of the 1A-rated Molex part?

A: Yes. The higher current rating of Samtec MMS parts (3.9A per contact) exceeds the original 1A specification. This provides additional design margin and is fully compatible with applications designed for the original 1A rating.

Q: What packaging options are available for these substitutes?

A: The 3M 150224-6002-RB is supplied in tray packaging. Samtec MMS variants are available in tube, bulk, or unspecified packaging depending on the specific part number. Confirm packaging requirements with your procurement specification.
