Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0791098455 is determined by the following critical parameters that must remain constant:

• 12-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 of -55°C ~ 125°C
• ROHS3 compliance and MSL 1 rating

The Samtec TLE-106-01-G-DV-K-TR meets these core substitution criteria. Both connectors share identical pitch, position count, row configuration, mounting type, termination method, and fastening type. Both are ROHS3 compliant with MSL 1 ratings and operate across the same temperature range. The substitute part is classified as a pass-through receptacle variant, which maintains mechanical and electrical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791098455 and Samtec TLE-106-01-G-DV-K-TR are active production parts with ROHS3 compliance and MSL 1 ratings. The connectors are mechanically and electrically interchangeable based on pitch, position count, row spacing, mounting type, and termination method. The Samtec substitute offers a pass-through receptacle configuration, which provides additional design flexibility for applications requiring signal pass-through capability. Both parts maintain identical operating temperature ranges and regulatory compliance status. Selection between these parts should be based on availability, lead time requirements, and specific application needs for pass-through functionality.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TLE-106-01-G-DV-K-TR directly replace the Molex 0791098455 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079"), position count (12), row configuration (2 rows at 0.079" spacing), surface mount termination, and push-pull fastening. Mechanical and electrical compatibility is maintained. The primary difference is the pass-through receptacle design of the Samtec part, which does not affect standard board-to-board or cable applications.

Q: What is the difference in gold plating thickness between these parts?

A: The Molex 0791098455 features 30.0µin (0.76µm) gold plating on mating contacts, while the Samtec TLE-106-01-G-DV-K-TR has 10.0µin (0.25µm). Both thicknesses are within industry standards for gold-plated connectors and provide adequate corrosion resistance and electrical conductivity for the specified 1A to 3.2A per contact current ratings.

Q: Are there differences in insulation material between these connectors?

A: The Molex part uses glass-filled Liquid Crystal Polymer (LCP), while the Samtec part uses unfilled LCP. Both materials provide equivalent mechanical and thermal performance across the -55°C ~ 125°C operating range. The glass-filled variant in the Molex connector offers marginally enhanced rigidity, though this does not affect functional compatibility.

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

A: Yes. Both the Molex 0791098455 and Samtec TLE-106-01-G-DV-K-TR are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8536.69.4040). Both have MSL 1 ratings with unlimited shelf life under controlled storage conditions.

Q: What is the significance of the pass-through receptacle design in the Samtec part?

A: The pass-through configuration allows signal routing through the connector body, enabling applications where signals must be transmitted to additional downstream connectors or components. For standard board-to-board or cable termination applications, this feature does not impact compatibility or performance.
