Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0791098657 is determined by strict alignment of the following core parameters:

• 16-position receptacle configuration
• 0.079" (2.00mm) mating pitch
• 2-row layout with 0.079" row spacing
• Surface mount solder termination
• Push-pull fastening mechanism
• Gold-plated mating contacts
• Operating temperature range -55°C to 125°C
• Phosphor bronze contact material
• Square contact geometry

The identified substitute parts maintain these critical parameters. Variations in packaging format (Tube vs. Tape & Reel), insulation material composition, current rating, voltage rating, and flammability classification do not preclude functional substitution when the core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with RoHS requirements. Selection between the Molex 0791098657 and substitute parts should be based on the following criteria:

Amphenol ICC 55510-116LF (Tube Packaging): This substitute is suitable for applications where tube packaging is preferred over tape and reel format. The part provides higher current capacity (2A vs. 1A) and voltage rating (200V vs. 125V) with UL94 V-0 flammability rating. Insulation material is plastic-based rather than glass-filled thermoplastic.

Amphenol ICC 55510-116TRLF (Tape & Reel Packaging): This substitute maintains tape and reel packaging identical to the main part, offering the same advantages as the tube variant with packaging continuity for automated assembly. REACH status is listed as affected, requiring compliance verification for specific applications.

Samtec TLE-108-01-G-DV-P-TR (Pass-Through Configuration): This substitute provides the highest current rating (3.2A per contact) and features pass-through connector capability. Insulation material is liquid crystal polymer (LCP). Contact finish thickness on mating surfaces is reduced (10.0µin vs. 30.0µin), and voltage rating is not specified.

All substitute parts are active products with unlimited moisture sensitivity level (MSL 1) and maintain the required operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 55510-116LF be used as a direct replacement for the Molex 0791098657?

A: Yes, the 55510-116LF maintains all critical electrical and mechanical parameters including 16-position configuration, 0.079" pitch, 2-row layout, surface mount solder termination, and push-pull fastening. The primary difference is packaging format (tube vs. tape and reel). Higher current and voltage ratings provide additional design margin.

Q: What is the difference between the two Amphenol ICC variants?

A: The 55510-116LF is supplied in tube packaging, while the 55510-116TRLF is supplied in tape and reel format. Both parts are electrically and mechanically identical. Selection depends on assembly process requirements and inventory management preferences.

Q: Why does the Samtec TLE-108-01-G-DV-P-TR have a lower contact finish thickness?

A: The Samtec part specifies 10.0µin (0.25µm) gold plating on mating contacts compared to 30.0µin (0.76µm) for the Molex and Amphenol parts. This reduced thickness does not preclude substitution but may affect contact durability in high-cycle mating applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0791098657 and Samtec TLE-108-01-G-DV-P-TR are ROHS3 compliant. The Amphenol ICC parts are RoHS compliant. All parts meet RoHS requirements for lead-free construction.

Q: What is the significance of the pass-through connector designation on the Samtec part?

A: The Samtec TLE-108-01-G-DV-P-TR is configured as a pass-through receptacle, allowing signal routing through the connector body. This feature does not affect basic substitution compatibility but may provide additional design flexibility for specific applications.

Q: Can I use the higher current-rated substitutes in place of the Molex part?

A: Yes. The Amphenol ICC parts (2A rating) and Samtec part (3.2A per contact rating) provide higher current capacity than the Molex 0791098657 (1A rating). Substitution is electrically valid when the application current requirement does not exceed the original part's 1A specification.

Q: What is the impact of different insulation materials on substitution?

A: The Molex part uses glass-filled thermoplastic insulation, Amphenol ICC parts use plastic insulation, and the Samtec part uses liquid crystal polymer (LCP). All materials are suitable for the specified operating temperature range (-55°C to 125°C) and do not affect mechanical compatibility or electrical performance in standard applications.
