Molex 0791098656 Equivalent & Substitute Parts

Part Overview

The Molex 0791098656 is a 14-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount applications in the Milli-Grid 79109 series. This connector features gold-plated mating contacts, push-pull fastening, and is rated for 1A at 125V across operating temperatures from -55°C to 125°C. The part is ROHS3 compliant and currently active in production with 1016 units in stock.

Equivalent and substitute parts are necessary when the original Molex part is unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility allows for functionally compatible alternatives from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0791098656 is based on strict electrical and mechanical compatibility across the following critical parameters:

• 14-position receptacle configuration with female socket contacts
• 0.079" (2.00mm) mating pitch and row spacing
• Surface mount solder termination with push-pull fastening
• Gold-plated mating contacts on phosphor bronze base material
• Operating temperature range of -55°C to 125°C
• ROHS3 compliance and MSL 1 rating

The Samtec MMS series receptacles meet these core requirements. Substitutes are differentiated by packaging format (Tube versus Tape & Reel), contact finish thickness specifications, and insulation material composition (Liquid Crystal Polymer versus Glass Filled Thermoplastic). These variations do not affect functional interchangeability for board-to-board or cable connection applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and MSL 1 ratings, matching the regulatory and environmental requirements of the original Molex 0791098656.

For automated assembly processes requiring Tape & Reel packaging, select either Samtec MMS-107-02-F-DV-K-TR or MMS-107-02-L-DV-P-TR. The MMS-107-02-F-DV-K-TR variant includes Pick and Place features and maintains 3.00µin (0.076µm) mating contact finish thickness. The MMS-107-02-L-DV-P-TR variant also includes Pick and Place features with 10.0µin (0.25µm) mating contact finish thickness.

For manual assembly or applications where tube packaging is acceptable, Samtec MMS-107-02-F-DV or MMS-107-02-L-DV-A are available. The MMS-107-02-L-DV-A includes Board Guide features.

All Samtec MMS series substitutes support the same 14-position, 0.079" pitch configuration and push-pull fastening mechanism as the original part.

Frequently Asked Questions (FAQ)

Q: Are all listed Samtec MMS parts electrically interchangeable with the Molex 0791098656?

A: Yes. All substitute parts share identical connector type, position count, mating pitch, row spacing, termination method, and fastening mechanism. They are electrically and mechanically compatible for board-to-board and cable connection applications.

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

A: Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment. Tube packaging is suitable for manual assembly or lower-volume production. The electrical and mechanical performance of the connector is identical regardless of packaging format.

Q: How do the contact finish thickness variations affect part selection?

A: Contact finish thickness is specified in the part number designation. The Molex 0791098656 specifies 30.0µin (0.76µm) mating contact finish. Samtec MMS variants offer 3.00µin (0.076µm) or 10.0µin (0.25µm) options. These variations do not affect functional compatibility for standard applications.

Q: What is the significance of the Board Guide feature in MMS-107-02-L-DV-A?

A: The Board Guide feature provides mechanical alignment assistance during connector mating. This is a design enhancement that does not affect electrical performance or interchangeability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed Samtec MMS series parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original Molex 0791098656.
