Molex 0791099210 Equivalent & Substitute Parts

Part Overview

The Molex 0791099210 is a 10-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. The part is active in production and RoHS3 compliant, making it suitable for automotive, general purpose, and telecommunications applications.

Equivalent and substitute parts are identified based on matching electrical and mechanical parameters: connector type (receptacle), contact configuration (10 positions, 2 rows), pitch spacing (0.079"), mounting method (surface mount), termination (solder), fastening type (push-pull), contact material (phosphor bronze with gold finish), and operating temperature range (-55°C to 125°C).

Key Parameters

Substitute Part Grouping Explanation

Samtec Inc. MMS series receptacle connectors are qualified substitutes for the Molex 0791099210 based on matching core electrical and mechanical parameters. All substitute parts share the following critical specifications:

• Connector type: Receptacle with female socket contacts
• Position count and configuration: 10 positions in 2-row arrangement
• Pitch spacing: 0.079" (2.00mm) mating pitch and row spacing
• Mounting method: Surface mount with solder termination
• Fastening mechanism: Push-pull
• Contact material: Phosphor bronze with gold mating finish
• Operating temperature range: -55°C to 125°C
• Compliance: RoHS3 compliant, MSL 1 (Unlimited)

Substitute parts differ in packaging format (Tube or Tape & Reel), contact finish thickness specifications, insulation height tolerances, and optional features (Board Guide, Pick and Place). These variations do not affect functional interchangeability in applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

All Samtec MMS-105 series receptacle connectors listed are functionally equivalent to the Molex 0791099210 for applications requiring 10-position, 0.079" pitch surface mount connectors with push-pull fastening and gold-plated contacts. Selection among substitute parts should be based on packaging requirements and inventory availability.

For Tape & Reel packaging with Pick and Place features, MMS-105-02-F-DV-K-TR and MMS-105-02-L-DV-K-TR are available with 1947 and 8536 units in stock respectively. For Tube packaging, MMS-105-02-F-DV offers 2438 units in stock. All parts maintain RoHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes and long-term storage without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Are Samtec MMS-105 series connectors mechanically compatible with the Molex 0791099210?

A: Yes. Both the main part and all substitute parts share identical mating pitch (0.079"), row spacing (0.079"), number of positions (10 in 2 rows), and push-pull fastening mechanism. Mating interfaces are fully compatible.

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

A: Tube packaging (MMS-105-02-F-DV, MMS-105-02-L-DV-K, MMS-105-02-L-DV-A) is suitable for manual assembly or lower-volume production. Tape & Reel packaging (MMS-105-02-F-DV-K-TR, MMS-105-02-L-DV-K-TR, MMS-105-02-L-DV-P-TR) is designed for automated pick-and-place assembly equipment. Both packaging formats contain the same connector component.

Q: What do the suffix codes (F, L, K, P, A, DV) in the Samtec part numbers indicate?

A: These codes represent design variations including contact finish thickness, insulation height, board guide presence, and pick-and-place compatibility. All variations maintain the core electrical and mechanical specifications required for substitution.

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

A: Yes, provided your assembly process supports the packaging format. The connector component itself is identical; only the packaging and presentation differ.

Q: Are there current rating differences between the main part and substitutes?

A: The Molex 0791099210 is rated at 1A per contact. Samtec MMS-105 series parts are rated at 3.9A per contact, providing higher current capacity. This makes them suitable for applications requiring the original 1A rating and for applications requiring higher current handling.

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All listed substitute parts operate across the -55°C to 125°C temperature range, matching the Molex 0791099210 specification.
