Molex 0791098457 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0791098457 is a 16-position receptacle connector in the Milli-Grid 79109 series, designed for surface mount applications with 0.079" (2.00mm) pitch. This connector is actively produced and widely used in automotive, telecommunications, and general-purpose applications. The part features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 125°C. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit functional equivalents.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0791098457 is determined by strict alignment of the following critical parameters:

• 16-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
• Phosphor bronze contact material
• Liquid Crystal Polymer insulation
• Operating temperature range of -55°C to 125°C
• ROHS3 compliance

The Samtec TLE-108-01-G-DV-P-TR meets all critical substitution criteria. Both connectors share identical position count, pitch, row configuration, mounting method, and environmental specifications. Functional compatibility is established through matching mechanical and electrical interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791098457 and Samtec TLE-108-01-G-DV-P-TR are active products with ROHS3 compliance and identical regulatory classifications. Selection between these parts is based on availability, lead time, and cost considerations. The Samtec part features pass-through connector capability and higher current rating per contact (3.2A versus 1A), which may provide additional design flexibility in applications requiring higher current density. Both parts maintain MSL 1 rating and are suitable for immediate use without baking requirements.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TLE-108-01-G-DV-P-TR directly replace the Molex 0791098457 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079"), position count (16), row configuration (2 rows), mounting method (surface mount), and termination type (solder). Mechanical and electrical interfaces are compatible.

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

A: The Samtec part includes pass-through capability, allowing signal routing through the connector body. This does not affect substitution compatibility for standard board-to-board or cable applications.

Q: Are there differences in contact current ratings between these parts?

A: The Molex part is rated at 1A per contact, while the Samtec part is rated at 3.2A per contact. Applications requiring higher current density may benefit from the Samtec option.

Q: Do both parts require the same PCB footprint?

A: Both connectors share identical pitch (0.079"), row spacing (0.079"), and position count (16). PCB footprints are mechanically compatible. Verify insulation height differences (Molex: 0.175", Samtec: 0.177") for clearance in height-constrained applications.

Q: Are both parts available in the same packaging format?

A: Yes. Both the Molex 0791098457 and Samtec TLE-108-01-G-DV-P-TR are supplied in Tape & Reel (TR) packaging suitable for automated assembly.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8536.69.4040. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.
