Molex 0791090011 Equivalent & Substitute Parts

Part Overview

The Molex 0791090011 is a 24-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount applications in board-to-board and cable interconnect solutions. This connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 125°C. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from Samtec Inc. provide compatible electrical and mechanical interfaces while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0791090011 is based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant across all substitute parts:

• 24-position receptacle configuration
• 0.079" (2.00mm) mating pitch
• 2-row layout with 0.079" (2.00mm) row spacing
• Surface mount solder termination
• Push-pull fastening mechanism
• Gold-plated mating contacts
• Operating temperature range -55°C to 125°C
• Phosphor bronze contact material
• Liquid crystal polymer insulation

The Samtec TLE series receptacles (TLE-112-01-G-DV-A-K, TLE-112-01-G-DV-A-K-TR, and TLE-112-01-G-DV-A-P) meet all these core requirements. These parts are functionally equivalent with enhanced current ratings and active product status. Packaging variations (Tube vs. Tape & Reel) and minor design enhancements (board guide, pick and place features) do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The Samtec TLE-112-01-G-DV-A-K, TLE-112-01-G-DV-A-K-TR, and TLE-112-01-G-DV-A-P are direct functional equivalents to the obsolete Molex 0791090011. Selection among these three variants depends on procurement and assembly requirements:

TLE-112-01-G-DV-A-K (Tube Packaging): Suitable for low-volume applications and manual assembly processes. Provides standard tube packaging with board guide features.

TLE-112-01-G-DV-A-K-TR (Tape & Reel Packaging): Optimized for high-volume automated assembly. Tape & reel format enables pick-and-place machine compatibility. Highest inventory availability (3390 pcs).

TLE-112-01-G-DV-A-P (Tube Packaging with Gold Post Finish): Tube packaging variant with gold-plated post finish, providing enhanced contact durability for repeated mating cycles.

All three Samtec alternatives offer ROHS3 compliance, addressing regulatory requirements that the obsolete Molex part does not meet. The Samtec parts deliver superior current ratings (3.2A per contact vs. 1A), providing design margin for existing and future applications. Mechanical and electrical interchangeability is confirmed across all parameters specified in this reference.

Frequently Asked Questions (FAQ)

Q: Are the Samtec TLE-112 series connectors mechanically interchangeable with the Molex 0791090011?

A: Yes. Both the main part and all substitute parts share identical mating pitch (0.079"), row spacing (0.079"), number of positions (24), and push-pull fastening mechanism. Insulation height variance (0.175" vs. 0.177") is within acceptable tolerance for board-to-board and cable applications.

Q: What is the difference between the three Samtec substitute options?

A: The three variants differ in packaging format and contact finish. TLE-112-01-G-DV-A-K and TLE-112-01-G-DV-A-P use tube packaging suitable for manual assembly. TLE-112-01-G-DV-A-K-TR uses tape & reel format for automated pick-and-place assembly. TLE-112-01-G-DV-A-P includes gold-plated post finish, while the other two variants do not specify post finish.

Q: Can I use these substitutes in existing designs without PCB layout modifications?

A: Yes. The mating pitch, row spacing, number of positions, and mounting type are identical. PCB footprints designed for the Molex 0791090011 are compatible with all three Samtec alternatives.

Q: What is the significance of the higher current rating in the Samtec parts?

A: The Samtec TLE-112 series supports 3.2A per contact compared to 1A for the Molex part. This higher rating provides design margin and supports higher-power applications without requiring circuit redesign.

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

A: Yes. The Molex 0791090011 is RoHS non-compliant, while all three Samtec alternatives are ROHS3 compliant. For applications subject to RoHS regulations, the Samtec parts are required.

Q: Which substitute should I select for high-volume production?

A: TLE-112-01-G-DV-A-K-TR (tape & reel) is recommended for high-volume automated assembly due to pick-and-place compatibility and highest inventory availability.
