Molex 0791070014 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0791070014 is a 30-position receptacle connector with 0.079" (2.00mm) pitch, designed for through-hole board-to-board or cable applications. This connector is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part features gold-plated mating contacts, tin-lead post finish, and operates across -55°C to 125°C. Active alternatives from 3M, TE Connectivity, and Samtec provide direct functional equivalence with improved compliance status.

Substitute Part Grouping Explanation

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

Connector Type & Contact Configuration: Receptacle, female socket, 30 positions
Pitch & Spacing: 0.079" (2.00mm) mating pitch with 0.079" row spacing
Mounting & Termination: Through-hole solder termination with push-pull fastening
Mating Contact Finish: Gold plating required
Insulation Color: Black
Contact Shape: Square

All substitute parts listed meet these core mechanical and electrical compatibility criteria. Variations in post finish, insulation material, contact finish thickness, and compliance certifications do not affect functional interchangeability in the connector interface.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a lower operating temperature maximum (105°C vs. 125°C)?

A: Temperature compatibility depends on your application requirements. If your design operates within -40°C to 105°C, the 3M 150230-6002-RB and TE Connectivity 3-1470209-8 are suitable. For applications requiring the full -55°C to 125°C range, use Samtec MMS series or the original Molex part.

Q: What is the difference between the Samtec MMS variants (S-DV, F-DV, H-DV, LM-DV)?

A: All Samtec MMS-115-01 variants share identical mechanical and electrical specifications. Differences exist in contact finish post material and mating contact finish thickness. MMS-115-01-S-DV and MMS-115-01-LM-DV feature tin post finish, MMS-115-01-F-DV features tin post finish, and MMS-115-01-H-DV features gold post finish. Selection depends on post finish requirements for your application.

Q: Is the Molex 0791070014 still available despite being obsolete?

A: Yes, 1151 pieces are currently in stock as new original inventory. However, active alternatives are recommended for new designs and long-term production continuity.

Q: What packaging options are available?

A: The 3M 150230-6002-RB and TE Connectivity 3-1470209-8 are supplied in trays. Samtec MMS series connectors are supplied in tubes.

Q: Are all substitute parts RoHS compliant?

A: Yes, all active substitute parts listed are RoHS3 compliant. The original Molex 0791070014 is RoHS non-compliant.

Q: Can I interchange these connectors on existing PCBs designed for the Molex 0791070014?

A: Yes. All substitute parts maintain identical pitch (0.079"), row spacing (0.079"), through-hole mounting, and push-pull fastening. PCB footprints are mechanically compatible. Verify post finish requirements if your design specifies tin or gold plating.
