Molex 0791098469 Equivalent & Substitute Parts

Part Overview

The Molex 0791098469 is a 40-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 is rated for 1A at 125V across operating temperatures from -55°C to 125°C. The part is actively produced and widely used in automotive, telecommunications, and general-purpose applications.

Equivalent and substitute parts are identified when inventory constraints, packaging requirements, or design modifications necessitate alternative connector solutions that maintain electrical and mechanical compatibility within the same application category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0791098469 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• 40-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
• Operating temperature range of -55°C to 125°C
• Liquid Crystal Polymer insulation material
• Phosphor bronze contact material
• ROHS3 compliance and MSL 1 rating

The substitute parts identified are manufactured by Samtec Inc. and include both standard receptacle connectors (MMS series) and pass-through receptacle variants (TLE series). These parts maintain the core electrical and mechanical specifications required for board-to-board and cable applications while offering variations in packaging format and contact current ratings.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original Molex 0791098469 connector.

The Samtec MMS series (MMS-120-02-F-DV and MMS-120-02-S-DV) are standard receptacle connectors with identical mechanical and electrical compatibility. These parts are supplied in tube packaging rather than tape and reel format. The MMS-120-02-F-DV and MMS-120-02-S-DV differ in contact finish thickness specifications but maintain the same mating contact gold plating and overall performance envelope.

The Samtec TLE series (TLE-120-01-G-DV-A-P and TLE-120-01-G-DV-K-TR) are pass-through receptacle variants that provide additional design flexibility for applications requiring signal routing through the connector body. The TLE-120-01-G-DV-K-TR is supplied in tape and reel packaging, matching the original part's format, while the TLE-120-01-G-DV-A-P is supplied in tube packaging.

Selection between standard receptacle (MMS series) and pass-through receptacle (TLE series) depends on application requirements. Packaging format selection (tape and reel versus tube) should align with assembly process specifications and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Are the Samtec MMS and TLE series connectors mechanically compatible with the Molex 0791098469?

A: Yes. All substitute parts maintain the same 40-position configuration, 0.079" (2.00mm) pitch, 2-row layout, surface mount solder termination, and push-pull fastening mechanism. Mating interfaces are compatible with connectors designed for the Molex 0791098469.

Q: What is the difference between the MMS and TLE series substitutes?

A: The MMS series are standard receptacle connectors. The TLE series are pass-through receptacle connectors, which allow signal routing through the connector body for applications requiring additional interconnect flexibility. Both series maintain the same core electrical and mechanical specifications.

Q: Does packaging format affect electrical performance?

A: No. Tape and reel (TR) and tube packaging formats do not affect electrical performance or connector specifications. Packaging selection should be based on assembly process requirements and inventory management practices.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The Molex 0791098469 and all identified Samtec substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What are the current rating differences between substitute parts?

A: The Molex 0791098469 is rated at 1A. The Samtec MMS series are rated at 3.9A per contact, and the Samtec TLE series are rated at 3.2A per contact. Higher current ratings in substitute parts do not affect compatibility and provide additional design margin for applications requiring increased current capacity.

Q: Can I use TLE-120-01-G-DV-K-TR as a direct replacement for the Molex 0791098469?

A: Yes. The TLE-120-01-G-DV-K-TR maintains identical mechanical and electrical specifications, including tape and reel packaging format. The pass-through design provides additional functionality without compromising compatibility with existing mating connectors.
