Molex 0791098456 Equivalent & Substitute Parts

Part Overview

The Molex 0791098456 is a 14-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount applications in the Milli-Grid 79109 series. This connector features gold-plated mating contacts, push-pull fastening, and is rated for 1A at 125V across operating temperatures from -55°C to 125°C. The part is active in production and ROHS3 compliant with unlimited moisture sensitivity rating.

Equivalent substitute parts are necessary when the original Molex part is unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility demands connector variants with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0791098456 are qualified based on the following critical parameters that must match or exceed the original specification:

Mandatory Matching Parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 14
• Pitch - mating: 0.079" (2.00mm)
• Number of rows: 2
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Surface mount
• Termination: Solder
• Fastening type: Push-pull
• Contact material: Phosphor bronze
• Contact finish - mating: Gold
• Insulation material: Liquid Crystal Polymer (LCP)
• Operating temperature range: -55°C to 125°C minimum
• RoHS compliance: ROHS3 compliant

Packaging Variants: Substitute parts are available in Tape & Reel (TR) and Tube packaging formats. These packaging differences do not affect electrical or mechanical compatibility but address specific manufacturing and assembly requirements.

Contact Rating Differences: Samtec MMS series substitutes are rated at 3.9A per contact, which exceeds the original Molex 1A rating. This higher current capacity is compatible with the original application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance and unlimited moisture sensitivity rating, matching the regulatory and environmental requirements of the original Molex 0791098456.

Packaging Selection:

• Tape & Reel (TR) packaging: MMS-107-02-F-DV-K-TR and MMS-107-02-L-DV-P-TR are suitable for automated pick-and-place assembly processes
• Tube packaging: MMS-107-02-F-DV and MMS-107-02-L-DV-A are suitable for manual assembly or lower-volume production

Feature Variants:

• MMS-107-02-F-DV-K-TR and MMS-107-02-L-DV-P-TR include pick-and-place features
• MMS-107-02-L-DV-A includes board guide feature

All Samtec MMS series substitutes provide higher current capacity (3.9A per contact) than the original specification (1A), ensuring compatibility with existing circuit designs while offering enhanced electrical performance margin.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically compatible with the Molex 0791098456? A: Yes. All substitute parts share identical connector type, contact configuration, pitch, row spacing, mounting type, termination method, fastening type, contact material, mating finish, insulation material, and operating temperature range. The Samtec MMS series provides higher current capacity per contact, which is compatible with original applications.

Q: What is the difference between Tape & Reel and Tube packaging? A: Tape & Reel packaging is designed for automated assembly equipment with pick-and-place capability. Tube packaging is used for manual assembly or lower-volume applications. Both packaging formats contain identical connector components.

Q: Can I substitute a Tube-packaged part for a Tape & Reel part in production? A: Packaging format selection depends on manufacturing process requirements. Tape & Reel parts are optimized for automated assembly lines, while Tube packaging is suitable for manual or semi-automated processes. The connector components themselves are identical.

Q: What does the higher current rating of Samtec MMS series mean for my application? A: The Samtec MMS-107 series is rated at 3.9A per contact compared to the Molex 1A rating. This higher capacity provides additional electrical performance margin and is fully compatible with applications designed for the original 1A specification.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the environmental and regulatory compliance of the original Molex 0791098456.

Q: What is the difference between MMS-107-02-F-DV and MMS-107-02-L-DV variants? A: The F-DV variant is a standard receptacle connector. The L-DV variant includes a board guide feature. Both variants are electrically and mechanically compatible with the original part; the board guide provides additional mechanical alignment during mating.
