Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0791098412 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Parameters:

• Number of positions: 26
• Pitch - mating: 0.079" (2.00mm)
• Number of rows: 2
• Row spacing - mating: 0.079" (2.00mm)
• Connector type: Receptacle
• Contact type: Female socket
• Mounting type: Surface mount
• Termination: Solder
• Fastening type: Push-pull
• Contact finish - mating: Gold
• Operating temperature range: -55°C ~ 125°C
• Insulation material: Liquid Crystal Polymer (LCP)
• Contact shape: Square
• Contact material: Phosphor Bronze

The Samtec TLE-113 series parts (TLE-113-01-G-DV-A and TLE-113-01-G-DV-A-K-TR) meet all core compatibility parameters. Both variants are pass-through receptacle connectors with identical electrical and mechanical specifications. The primary differences are packaging format (Tube versus Tape & Reel) and current rating per contact (3.2A versus 1A for the Molex part).

Parameter Comparison

Engineering Selection Recommendations

Both Samtec TLE-113 variants are qualified substitutes for the Molex 0791098412 based on electrical and mechanical compatibility. All three parts maintain active product status and ROHS3 compliance.

Samtec TLE-113-01-G-DV-A-K-TR is the preferred substitute when packaging format matches the original specification. This variant is supplied in Tape & Reel format, identical to the Molex part, and includes pick-and-place features suitable for automated assembly. Current rating of 3.2A per contact exceeds the Molex specification of 1A, providing additional design margin.

Samtec TLE-113-01-G-DV-A is suitable for applications where Tube packaging is acceptable. This variant offers the same electrical and mechanical performance as the TR version but requires different handling and placement procedures during assembly.

Minor dimensional variations exist: Samtec parts have insulation height of 0.177" (4.50mm) compared to Molex 0.175" (4.45mm), and contact finish thickness on mating surfaces is 10.0µin (0.25µm) versus Molex 15.0µin (0.38µm). These variations remain within acceptable tolerances for board-to-board and cable connector applications.

Frequently Asked Questions (FAQ)

Q: Are the Samtec TLE-113 connectors mechanically compatible with the Molex 0791098412?

A: Yes. Both Samtec variants share identical mating pitch (0.079"), row configuration (2 rows), position count (26), and push-pull fastening mechanism. Insulation height differences (0.002") are within standard manufacturing tolerances and do not affect mechanical fit.

Q: What is the difference between TLE-113-01-G-DV-A and TLE-113-01-G-DV-A-K-TR?

A: The primary difference is packaging. TLE-113-01-G-DV-A is supplied in Tube format, while TLE-113-01-G-DV-A-K-TR is supplied in Tape & Reel format with pick-and-place features. Electrical and mechanical specifications are identical. Select based on assembly process requirements.

Q: Can I use the Samtec parts in applications rated for 1A if they are rated for 3.2A per contact?

A: Yes. The higher current rating of Samtec parts (3.2A per contact) is a superset of the Molex specification (1A). Samtec parts are suitable for all applications within the 1A specification and provide additional design margin for higher-current applications.

Q: Are there dimensional concerns with the 0.002" insulation height difference?

A: No. The insulation height difference between Molex (0.175") and Samtec (0.177") is within standard connector manufacturing tolerances and does not affect board layout, mating performance, or mechanical clearance in typical applications.

Q: Do all three parts have the same compliance certifications?

A: All three parts are ROHS3 compliant and carry MSL rating 1 (Unlimited). Both Samtec variants maintain active product status. Compliance certifications are equivalent across all three parts.

Q: What is the difference in contact finish thickness, and does it affect performance?

A: Molex specifies 15.0µin (0.38µm) mating contact finish, while Samtec specifies 10.0µin (0.25µm). Both thicknesses provide adequate gold plating for signal integrity and corrosion resistance in standard operating environments. The difference does not affect electrical performance or reliability.
