Molex 0791098611 Equivalent & Substitute Parts

Part Overview

The Molex 0791098611 is a 24-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 support for board-to-board or cable interconnections. The part is active in production and ROHS3 compliant. Equivalent parts are identified when electrical and mechanical parameters align within acceptable tolerances for the rectangular connector category, enabling direct substitution in applications where connector performance requirements are met.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0791098611 are qualified based on the following critical parameters that determine functional equivalence:

• Connector Type & Configuration: Receptacle with 24 positions in 2-row arrangement
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting Technology: Surface mount termination with solder connection
• Fastening Mechanism: Push-pull fastening system
• Contact Interface: Gold-plated mating surface for signal integrity
• Environmental Rating: Operating temperature range -55°C ~ 125°C
• Compliance: ROHS3 compliance and EAR99 classification

The identified substitutes from Samtec Inc. (TLE-112-01-G-DV-A and TLE-112-01-G-DV-A-K-TR) meet these core parameters. Differences in contact current rating, insulation material, and packaging format do not preclude substitution when application requirements are satisfied by the substitute specifications.

Parameter Comparison

Engineering Selection Recommendations

Both Samtec TLE-112 series connectors satisfy the core electrical and mechanical requirements for substitution with the Molex 0791098611. Selection between alternatives is determined by application-specific factors:

Samtec TLE-112-01-G-DV-A (Tube Packaging): This variant provides equivalent functionality with higher current capacity per contact (3.2A vs. 1A). The tube packaging format differs from the original tape & reel specification and may require process adjustment in automated assembly environments.

Samtec TLE-112-01-G-DV-A-K-TR (Tape & Reel Packaging): This variant maintains tape & reel packaging identical to the original part specification, enabling direct integration into existing pick-and-place assembly processes. The higher current rating and pass-through connector design provide enhanced performance characteristics while maintaining mechanical and electrical compatibility.

Both substitutes are ROHS3 compliant and active in production. The pass-through connector design of the Samtec alternatives offers additional functionality not present in the original Molex part. Insulation material differs (Liquid Crystal Polymer vs. Thermoplastic, Glass Filled), with LCP providing superior thermal and chemical resistance properties.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TLE-112-01-G-DV-A-K-TR directly replace the Molex 0791098611 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079"), row configuration (2 rows, 24 positions), mounting type (surface mount), fastening mechanism (push-pull), and operating temperature range (-55°C ~ 125°C). The tape & reel packaging format matches the original specification, supporting direct substitution in automated assembly processes.

Q: What is the difference between the two Samtec substitutes?

A: The primary difference is packaging format. TLE-112-01-G-DV-A is supplied in tube packaging, while TLE-112-01-G-DV-A-K-TR is supplied in tape & reel format with pick-and-place features. Both connectors are electrically and mechanically equivalent. The tape & reel variant is recommended for high-volume automated assembly.

Q: Are there differences in contact plating thickness?

A: Yes. The Molex 0791098611 specifies 15.0µin (0.38µm) gold plating on mating contacts, while both Samtec alternatives specify 10.0µin (0.25µm). Both thicknesses provide adequate corrosion protection and electrical conductivity for the specified voltage (125V) and current (1A minimum) ratings.

Q: What is the pass-through connector feature in the Samtec parts?

A: Pass-through design allows signal routing through the connector body, enabling daisy-chain or multi-level interconnection configurations. This feature is not present in the original Molex receptacle but does not prevent direct mechanical and electrical substitution.

Q: Are all three connectors ROHS3 compliant?

A: Yes. The Molex 0791098611 and both Samtec TLE-112 variants are ROHS3 compliant. All three parts carry EAR99 export classification and are suitable for applications requiring regulatory compliance in restricted substance directives.

Q: What insulation material differences exist?

A: The Molex part uses Thermoplastic, Glass Filled insulation, while Samtec alternatives use Liquid Crystal Polymer (LCP). LCP provides superior thermal stability, lower moisture absorption, and enhanced chemical resistance compared to glass-filled thermoplastic, supporting operation across the full -55°C ~ 125°C temperature range with improved dimensional stability.
