Molex 0791098606 Equivalent & Substitute Parts

Part Overview

The Molex 0791098606 is a 14-position receptacle connector in the Milli-Grid 79109 series, designed for surface mount applications with 0.079" (2.00mm) pitch. This connector features gold-plated mating contacts, push-pull fastening, and board guide functionality. The part is active and in production with 759 units currently in stock.

Equivalent and substitute parts are identified based on matching electrical and mechanical specifications, including connector type, position count, pitch, mounting method, and contact characteristics. Alternative sources provide equivalent functionality with variations in packaging, insulation material, and current rating capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0791098606 are qualified based on the following critical parameters:

Matching Criteria:

• Connector type: Receptacle with female socket contacts
• Position count: 14 positions
• Pitch specification: 0.079" (2.00mm) mating pitch with 0.079" row spacing
• Mounting method: Surface mount with solder termination
• Fastening mechanism: Push-pull connector system
• Contact material: Phosphor bronze with gold mating finish
• Operating temperature range: -55°C ~ 125°C
• Compliance: ROHS3 compliant with MSL 1 rating

Allowable Variations:

• Packaging format (Tube vs. Tape & Reel)
• Insulation material (Thermoplastic glass-filled vs. Liquid Crystal Polymer)
• Contact finish thickness on mating surface
• Current rating per contact
• Presence of board guide or pick-and-place features
• Insulation height tolerance within mechanical compatibility range

All four Samtec MMS-107 series variants meet these substitution criteria and are electrically and mechanically compatible with the Molex 0791098606.

Parameter Comparison

Engineering Selection Recommendations

All four Samtec MMS-107 series variants are qualified substitutes for the Molex 0791098606 based on electrical and mechanical compatibility. Selection between substitute options depends on application requirements and supply chain considerations:

MMS-107-02-F-DV (Tube Packaging): Standard tube packaging suitable for manual assembly or low-volume production. Samtec LCP insulation material provides enhanced thermal and chemical resistance compared to glass-filled thermoplastic.

MMS-107-02-F-DV-K-TR (Tape & Reel with Pick and Place): Tape & Reel packaging with pick-and-place feature designation. Recommended for automated assembly processes requiring reel-based component feeding.

MMS-107-02-L-DV-A (Tube with Board Guide): Tube packaging with board guide feature, functionally equivalent to the Molex original which includes board guide functionality. Provides mechanical alignment support during mating operations.

MMS-107-02-L-DV-P-TR (Tape & Reel with Board Guide and Pick and Place): Combines board guide feature with tape & reel packaging and pick-and-place designation. Optimal for automated assembly with mechanical alignment requirements.

All substitute parts maintain ROHS3 compliance and MSL 1 rating. The Samtec variants provide higher current rating capability (3.9A per contact vs. 1A) and LCP insulation material, which may offer performance advantages in specific thermal or chemical environments.

Frequently Asked Questions (FAQ)

Q: Are the Samtec MMS-107 series connectors electrically compatible with the Molex 0791098606?

A: Yes. All four Samtec variants share identical electrical specifications including 14-position configuration, 0.079" (2.00mm) pitch, phosphor bronze contacts with gold mating finish, push-pull fastening, and -55°C ~ 125°C operating temperature range. The higher current rating of the Samtec parts (3.9A per contact) is a performance enhancement over the Molex specification (1A).

Q: What is the difference between the Samtec variants?

A: The four MMS-107 variants differ in packaging format and mechanical features. MMS-107-02-F-DV and MMS-107-02-F-DV-K-TR lack board guide features, while MMS-107-02-L-DV-A and MMS-107-02-L-DV-P-TR include board guide functionality. Packaging options are Tube (standard) or Tape & Reel (TR) with pick-and-place designation for automated assembly.

Q: Can I substitute a Tape & Reel packaged part for a Tube packaged part?

A: Yes, from a functional standpoint. The connector itself is identical; only the packaging format differs. Tape & Reel packaging is optimized for automated pick-and-place assembly, while Tube packaging is suitable for manual assembly or lower-volume applications. Verify that your assembly process can accommodate the selected packaging format.

Q: Does the board guide feature affect mechanical compatibility?

A: The board guide feature provides additional mechanical alignment during mating but does not prevent compatibility with mating connectors. Parts with board guide (MMS-107-02-L-DV-A and MMS-107-02-L-DV-P-TR) are compatible with both guided and non-guided mating connectors. The Molex 0791098606 includes board guide functionality, making the Samtec L-series variants functionally equivalent.

Q: Are there compliance or certification differences between the Molex and Samtec parts?

A: Both the Molex 0791098606 and all Samtec MMS-107 variants are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. No compliance or certification differences exist between the parts.

Q: What is the impact of insulation material differences?

A: The Molex part uses thermoplastic glass-filled insulation, while Samtec variants use Liquid Crystal Polymer (LCP). LCP provides superior thermal stability, chemical resistance, and dimensional stability. This is a material enhancement that does not affect mechanical or electrical compatibility.

Q: Can I use the higher current rating of the Samtec parts in my application?

A: The Samtec MMS-107 series is rated for 3.9A per contact compared to the Molex 1A rating. If your application requires higher current capacity, the Samtec variants provide this capability. If your application is designed for 1A operation, the Samtec parts are fully compatible and provide additional current margin.
