Substitute Part Grouping Explanation

Substitute parts for the Molex 0791098662 are qualified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility:

26-position configuration with 0.079" (2.00mm) pitch maintained across all substitutes
2-row arrangement with identical row spacing
Push-pull fastening mechanism
Gold-plated mating contacts
Operating temperature range of -55°C to 125°C
Surface mount solder termination

Mechanical Compatibility:

Receptacle connector type with female socket contacts
Board-to-board or cable interconnection style
Square contact geometry
Phosphor bronze contact material

The Samtec TLE-113 series parts (TLE-113-01-G-DV-A and TLE-113-01-G-DV-A-K-TR) meet these core substitution criteria. Both variants are pass-through receptacles with identical electrical and mechanical interfaces. The primary distinction between substitutes is packaging format (Tube versus Tape & Reel) and current rating per contact (3.2A versus the original 1A specification).

Engineering Selection Recommendations

Both Samtec TLE-113 variants are qualified substitutes for the Molex 0791098662 based on matching electrical and mechanical specifications. Selection between substitute options depends on procurement and assembly requirements:

TLE-113-01-G-DV-A (Tube Packaging): Suitable for lower-volume applications or manual assembly processes. Inventory availability is 1171 pieces.

TLE-113-01-G-DV-A-K-TR (Tape & Reel Packaging): Optimized for automated pick-and-place assembly operations. Includes board guide and pick-and-place features. Inventory availability is 1568 pieces.

All three parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The Samtec substitutes provide higher current capacity per contact (3.2A versus 1A), which represents an operational advantage in applications where current distribution is a design consideration.

Frequently Asked Questions (FAQ)

Q: Can TLE-113-01-G-DV-A and TLE-113-01-G-DV-A-K-TR be used interchangeably with the Molex 0791098662?

A: Yes. Both Samtec parts are electrically and mechanically equivalent. The difference is packaging format: Tube versus Tape & Reel. The connector interface, pin configuration, and electrical performance are identical.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for manual handling and lower-volume assembly. Tape & Reel packaging is formatted for automated pick-and-place equipment and high-volume production. Both contain the same connector component.

Q: Are the Samtec substitutes compatible with existing Molex connector headers?

A: Yes. The 26-position, 0.079" (2.00mm) pitch configuration is standardized across both manufacturers. The receptacle connectors mate with compatible plug connectors from either manufacturer.

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

A: The Samtec TLE-113 series supports 3.2A per contact compared to 1A on the Molex part. This higher rating provides design margin in applications with elevated current requirements but does not affect compatibility or interchangeability.

Q: Are all three parts RoHS compliant?

A: Yes. The Molex 0791098662 and both Samtec TLE-113 variants are ROHS3 compliant and carry MSL 1 moisture sensitivity rating.

Q: What is the pass-through feature on the Samtec connectors?

A: Pass-through design allows signal routing through the connector body, enabling daisy-chain or multi-level interconnection configurations. This feature does not affect basic interchangeability with standard receptacle applications.
