Molex 0791098661 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0791098661 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 functionality for automated assembly. The part is active in production and widely used in automotive, telecommunications, and general-purpose applications requiring reliable board-to-board or cable interconnection.

Substitute parts are identified when equivalent electrical and mechanical parameters are met, enabling component interchangeability for procurement flexibility, inventory optimization, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0791098661 is determined by strict alignment of the following critical parameters:

• Connector Configuration: 24-position receptacle with 2-row arrangement
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting Technology: Surface mount with solder termination
• Mechanical Interface: Push-pull fastening with board guide
• Electrical Contact System: Gold-plated mating surface on phosphor bronze square contacts
• Environmental Compliance: ROHS3 compliance and MSL 1 rating
• Operating Range: -55°C to 125°C temperature specification

The Samtec TLE-112-01-G-DV-A-K-TR meets these core substitution criteria, maintaining mechanical and electrical compatibility while offering alternative packaging and enhanced current rating specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791098661 and Samtec TLE-112-01-G-DV-A-K-TR are active production components with ROHS3 compliance and MSL 1 ratings, confirming suitability for current manufacturing and long-term supply availability.

The Samtec TLE-112-01-G-DV-A-K-TR offers enhanced current-carrying capacity at 3.2A per contact compared to the Molex specification of 1A, providing additional electrical margin for applications requiring higher current density. The pass-through connector design of the Samtec part enables signal routing through the connector body, supporting applications with stacked or daisy-chained configurations.

Packaging differences exist: the Molex part is supplied in bulk format, while the Samtec equivalent is provided in tape and reel packaging, optimizing for high-volume automated assembly processes.

Selection between these parts should be based on application current requirements, connector stacking needs, and assembly process compatibility with tape and reel versus bulk packaging formats.

Frequently Asked Questions (FAQ)

Q: What defines compatibility between the Molex 0791098661 and Samtec TLE-112-01-G-DV-A-K-TR?

A: Both connectors share identical mechanical pitch (0.079"), row configuration (2 rows), position count (24), mounting method (surface mount), and contact system (gold-plated phosphor bronze). These parameters ensure physical and electrical interchangeability in board-to-board and cable applications.

Q: Can the Samtec part handle higher current than the Molex connector?

A: Yes. The Samtec TLE-112-01-G-DV-A-K-TR is rated for 3.2A per contact, while the Molex 0791098661 is rated for 1A. Applications requiring current levels between 1A and 3.2A per contact may benefit from the Samtec substitute.

Q: What is the difference between standard receptacle and pass-through receptacle designs?

A: The Samtec TLE-112-01-G-DV-A-K-TR features pass-through design, allowing signal transmission through the connector body. This enables stacked connector configurations and daisy-chaining applications not possible with standard receptacle designs.

Q: Are there packaging considerations when substituting these parts?

A: Yes. The Molex part is supplied in bulk packaging, while the Samtec equivalent uses tape and reel format. Tape and reel packaging is optimized for automated pick-and-place assembly, potentially reducing handling and improving placement accuracy in high-volume production environments.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity level), and operate across the -55°C to 125°C temperature range, confirming equivalent environmental performance and regulatory compliance.
