Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-103-02-F-DV be used as a direct replacement for the Molex 0791091202?

A: Yes. Both connectors share identical mating pitch (0.079"), row configuration (2 rows), position count (6), mounting type (surface mount), and fastening mechanism (push-pull). PCB footprints and mating interfaces are compatible.

Q: Are there differences in current rating between these parts?

A: The Molex 0791091202 specifies 1A current rating, while the Samtec MMS-103-02-F-DV specifies 3.9A per contact. The Samtec part supports higher current capacity and is suitable for applications requiring the Molex specification.

Q: What is the difference in contact finish thickness?

A: The Molex part has 15.0µin (0.38µm) gold plating on mating contacts, while the Samtec part has 3.00µin (0.076µm). Both provide gold-plated mating surfaces; the difference reflects different manufacturing specifications for the same functional requirement.

Q: Are both parts suitable for automotive applications?

A: The Molex 0791091202 explicitly lists automotive applications. The Samtec MMS-103-02-F-DV does not specify applications in the provided data. Verify application suitability with the manufacturer for the Samtec part if automotive qualification is required.

Q: What is the difference in insulation material?

A: The Molex part uses thermoplastic glass-filled insulation, while the Samtec part uses Liquid Crystal Polymer (LCP). Both materials are suitable for the specified operating temperature range (-55°C ~ 125°C) and provide equivalent mechanical performance for surface mount applications.

Q: Do both parts have the same packaging?

A: Yes. Both the Molex 0791091202 and Samtec MMS-103-02-F-DV are supplied in tube packaging.
