Key Parameters

Substitute Part Grouping Explanation

The Samtec TLE-106-01-G-DV-K-TR qualifies as an equivalent substitute based on the following critical parameters:

Matching Specifications:

• 12-position receptacle connector
• 0.079" (2.00mm) mating pitch
• 2-row configuration with 0.079" (2.00mm) row spacing
• Surface mount solder termination
• Push-pull fastening mechanism
• Gold-plated mating contacts
• Operating temperature range: -55°C ~ 125°C
• ROHS3 compliant
• MSL 1 (Unlimited)

Both connectors maintain identical mechanical and electrical interface geometry, allowing direct PCB footprint compatibility and mating with the same plug connectors.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791091205 and Samtec TLE-106-01-G-DV-K-TR are active production parts with ROHS3 compliance and MSL 1 rating, suitable for applications requiring unlimited moisture exposure without baking requirements.

The Samtec substitute offers higher current capacity (3.2A per contact versus 1A) and uses Liquid Crystal Polymer insulation material, which provides enhanced thermal and mechanical properties compared to glass-filled thermoplastic. The insulation height difference of 0.002" (0.05mm) is within typical PCB design tolerances and does not affect mechanical compatibility.

Selection between these parts should be based on supply chain availability, packaging requirements (tube versus tape & reel), and application current demands. Both maintain identical mating interface geometry and fastening characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TLE-106-01-G-DV-K-TR be used as a direct replacement for the Molex 0791091205?

A: Yes. Both connectors share identical mating pitch (0.079"), position count (12), row configuration (2 rows), and fastening mechanism (push-pull). PCB footprints are compatible, and mating with the same plug connectors is assured.

Q: What is the difference in current rating between these parts?

A: The Molex part is rated at 1A, while the Samtec substitute is rated at 3.2A per contact. Applications requiring higher current capacity benefit from the Samtec option without any mechanical or electrical interface changes.

Q: Are there packaging differences?

A: Yes. The Molex 0791091205 is supplied in tube packaging, while the Samtec TLE-106-01-G-DV-K-TR is supplied in tape & reel format. Tape & reel packaging is standard for automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level), requiring no special storage or handling conditions.

Q: What is the significance of the insulation material difference?

A: The Molex part uses glass-filled thermoplastic, while the Samtec part uses Liquid Crystal Polymer (LCP). LCP provides superior thermal stability and mechanical properties, particularly in high-temperature or high-stress applications.

Q: Are the contact finish thicknesses compatible?

A: Yes. Both use gold-plated mating contacts. The Molex part specifies 15.0µin (0.38µm) while the Samtec part specifies 10.0µin (0.25µm). Both thicknesses provide adequate corrosion resistance and electrical conductivity for the specified operating conditions.
