Engineering Selection Recommendations

Both the Molex 0791077217 and Samtec MMS-118-01-F-DV are Active product status connectors with ROHS3 compliance and EAR99 classification, qualifying them for equivalent use in applications requiring 36-position, 0.079" pitch receptacle connectors with push-pull fastening and through-hole solder termination.

The Samtec MMS-118-01-F-DV offers higher current capacity per contact (3.9A versus 1A) and extended contact post length (0.115" versus 0.075"), making it suitable for applications with elevated current requirements or specific PCB stack-up configurations. The Samtec part utilizes Liquid Crystal Polymer insulation material compared to the glass-filled thermoplastic of the Molex part, providing enhanced dimensional stability and thermal performance.

Selection between these parts should be based on specific application current requirements, PCB design constraints, and inventory availability. Both parts maintain identical mechanical footprint compatibility and electrical interface specifications for the connector pitch, row configuration, and mating contact finish.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-118-01-F-DV directly replace the Molex 0791077217 in existing designs?

A: Yes. Both connectors share identical mechanical footprint specifications including 36 positions, 0.079" (2.00mm) pitch, 2-row configuration with 0.079" row spacing, through-hole mounting, and push-pull fastening. PCB layout and mating connector compatibility remain unchanged.

Q: What are the differences in current handling between these parts?

A: The Molex 0791077217 is rated at 1A per connector, while the Samtec MMS-118-01-F-DV is rated at 3.9A per contact. Applications requiring higher current distribution should specify the Samtec part.

Q: How do the contact post lengths differ?

A: The Molex part features 0.075" (1.91mm) contact post length, while the Samtec part provides 0.115" (2.92mm). This difference affects PCB stack-up compatibility and should be verified against specific board thickness and layer requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the Molex 0791077217 and Samtec MMS-118-01-F-DV maintain ROHS3 compliance status.

Q: What is the difference in insulation material?

A: The Molex part uses thermoplastic with glass filler, while the Samtec part uses Liquid Crystal Polymer (LCP). LCP provides superior dimensional stability and thermal performance characteristics.

Q: What packaging formats are available?

A: The Samtec MMS-118-01-F-DV is supplied in tube packaging. Packaging specifications for the Molex part are not provided in the technical data.
