Molex 0791077215 Equivalent & Substitute Parts

Part Overview

The Molex 0791077215 is a 32-position receptacle connector from the Milli-Grid 79107 series, designed for board-to-board or cable applications. This through-hole connector features 0.079" (2.00mm) pitch mating with gold-plated contacts and is rated for 1A at 125V. The part is active and in production with 1047 units currently in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or when design requirements permit alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0791077215 are qualified based on the following critical parameters that must match or exceed the original specification:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 32
• Pitch - mating: 0.079" (2.00mm)
• Number of rows: 2
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Through hole
• Termination: Solder
• Fastening type: Push-pull
• Operating temperature range: -55°C ~ 125°C
• Contact material: Phosphor bronze
• Contact shape: Square

The Samtec MMS-116-01-F-DV and MMS-116-01-S-DV meet these core mechanical and electrical criteria. Both are 32-position receptacle connectors with identical pitch, row configuration, mounting method, and operating temperature range. Differences in contact finish thickness and insulation material do not preclude substitution when the application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Both Samtec MMS-116-01-F-DV and MMS-116-01-S-DV are qualified substitutes for the Molex 0791077215 based on matching mechanical and electrical specifications. All three parts are active products with ROHS3 compliance and EAR99 classification.

The Samtec alternatives provide higher current ratings (3.9A per contact versus 1A for the Molex part), which represents a performance advantage in applications requiring increased current capacity. The Samtec parts utilize Liquid Crystal Polymer (LCP) insulation material compared to the thermoplastic glass-filled material in the Molex connector; both materials are suitable for the specified operating temperature range.

Contact post length differs between the original and substitute parts (0.075" for Molex versus 0.115" for Samtec), which may affect PCB layout and assembly considerations. This dimensional difference must be evaluated against specific board design requirements.

Selection between MMS-116-01-F-DV and MMS-116-01-S-DV should be based on contact finish thickness requirements for the application, with MMS-116-01-S-DV providing thicker gold plating (30.0µin versus 3.00µin).

Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-116-01-F-DV or MMS-116-01-S-DV be used as direct replacements for the Molex 0791077215?

A: Yes, both Samtec parts meet the core mechanical and electrical specifications of the Molex connector. The 32-position configuration, 0.079" pitch, through-hole mounting, and operating temperature range are identical. However, the increased contact post length (0.115" versus 0.075") requires verification against PCB layout constraints.

Q: What is the difference between the two Samtec substitute parts?

A: Both MMS-116-01-F-DV and MMS-116-01-S-DV are mechanically and electrically identical. The primary difference is contact finish thickness on the mating surface: MMS-116-01-F-DV has 3.00µin gold plating, while MMS-116-01-S-DV has 30.0µin gold plating. Selection depends on contact durability and wear resistance requirements for the specific application.

Q: Are there any compliance or certification differences between these parts?

A: All three parts are ROHS3 compliant, carry EAR99 classification, and are active products in production. No compliance or certification differences exist that would restrict substitution.

Q: Does the higher current rating of the Samtec parts affect compatibility?

A: The Samtec parts are rated for 3.9A per contact compared to 1A for the Molex part. This higher rating does not create compatibility issues; it indicates the Samtec connectors can safely handle higher current loads. Applications designed for 1A operation will function correctly with the Samtec substitutes.

Q: What should be considered when switching from Molex to Samtec connectors?

A: Primary considerations are contact post length (0.115" for Samtec versus 0.075" for Molex), which affects PCB hole depth and assembly tooling, and insulation material (LCP versus thermoplastic glass-filled). Both materials support the operating temperature range. Contact finish thickness should be selected based on application requirements for contact durability.
