Substitute Part Grouping Explanation

Substitute parts for the Molex 0791098654 are qualified based on the following critical parameters:

Connector type, contact type, and position count (10-position receptacle, female socket)
Mating pitch and row spacing (0.079" / 2.00mm)
Surface mount termination with solder connection
Push-pull fastening mechanism
Gold-plated mating contact finish
Operating temperature range (-55°C ~ 125°C)
Contact material (Phosphor Bronze)
RoHS3 compliance and MSL 1 rating

Samtec Inc. MMS series connectors meet these core electrical and mechanical requirements. Variations in packaging (Tube vs. Tape & Reel), contact finish thickness, insulation material (LCP vs. thermoplastic), and optional features (Board Guide, Pick and Place) do not affect functional interchangeability for standard board-to-board or cable applications.

Engineering Selection Recommendations

All Samtec MMS-105 series variants listed are functionally equivalent to the Molex 0791098654 for standard board-to-board and cable connector applications. Selection among substitute parts should be based on:

Packaging Requirements: Choose Tape & Reel (TR) packaging for automated assembly processes. Tube packaging is suitable for manual or lower-volume assembly operations.

Feature Requirements: MMS-105-02-F-DV-A, MMS-105-02-L-DV-A-K-TR, and MMS-105-02-L-DV-K-TR include Board Guide features for improved alignment during mating. MMS-105-02-F-DV-K-TR, MMS-105-02-L-DV-A-K-TR, MMS-105-02-L-DV-K, MMS-105-02-L-DV-K-TR, and MMS-105-02-L-DV-P-TR include Pick and Place features for automated component handling.

Inventory Availability: MMS-105-02-L-DV-K-TR offers the highest stock level (8,536 units), followed by MMS-105-02-F-DV (2,438 units) and MMS-105-02-F-DV-K-TR (1,947 units).

Compliance: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, matching the original part's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Are Samtec MMS-105 series connectors mechanically compatible with Molex 0791098654?

A: Yes. Both connector families share identical mating pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), number of positions (10), and push-pull fastening mechanism. Mating interfaces are compatible.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is suitable for manual assembly and lower-volume production. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment and high-volume manufacturing.

Q: Do all substitute parts have the same current rating as the original Molex part?

A: The Molex 0791098654 is rated for 1A. Samtec MMS-105 series parts are rated for 3.9A per contact, providing higher current capacity. This does not affect compatibility; the higher rating ensures adequate performance in applications requiring the original 1A specification.

Q: What is the significance of the contact finish thickness variations?

A: Contact finish thickness variations (30.0µin for Molex, 3.00µin or 10.0µin for Samtec variants) do not affect functional interchangeability. All finishes provide adequate gold plating for reliable mating contact performance within the specified operating temperature range.

Q: Can I substitute MMS-105-02-L-DV-K-TR for MMS-105-02-F-DV?

A: Yes. Both are 10-position, 0.079" pitch receptacle connectors with identical electrical and mechanical specifications. The primary difference is packaging (Tape & Reel vs. Tube) and optional features (Pick and Place). Selection depends on assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All Samtec MMS-105 series variants listed are ROHS3 compliant and REACH unaffected, matching the regulatory status of the Molex 0791098654.
