Substitute Part Grouping Explanation

Substitute parts for the Molex 0791077265 are qualified based on the following critical parameters that must match or exceed the original specification:

Connector type: Receptacle with female socket contacts
Position count: 32 positions
Pitch and row spacing: 0.079" (2.00mm) mating pitch with 2-row configuration
Mounting: Through-hole solder termination with push-pull fastening
Contact finish: Gold-plated mating surface
Operating temperature range: -55°C to 125°C minimum
Regulatory compliance: ROHS3 compliant

The identified substitutes (MMS-116-01-F-DV and MMS-116-01-S-DV) from Samtec Inc. meet these core electrical and mechanical parameters, enabling direct functional replacement in applications requiring 32-position rectangular connectors with 2.00mm pitch.

Engineering Selection Recommendations

All three parts—the Molex 0791077265 and the Samtec MMS-116-01-F-DV and MMS-116-01-S-DV—are active products with ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on:

Inventory availability: Molex 0791077265 has 1130 units in stock; Samtec MMS-116-01-F-DV has 1096 units; Samtec MMS-116-01-S-DV has 648 units
Packaging format: Molex uses standard packaging; Samtec parts are supplied in tubes
Lead time and supply chain requirements for your application timeline
Existing connector ecosystem and mating plug compatibility in your design

All parts meet the same electrical performance, temperature range, and regulatory requirements for direct substitution in 32-position, 2.00mm pitch rectangular connector applications.

Frequently Asked Questions (FAQ)

Q: Can Samtec MMS-116-01-F-DV and MMS-116-01-S-DV be used interchangeably with the Molex 0791077265?

A: Yes. Both Samtec parts meet the core substitution criteria: 32-position receptacle configuration, 0.079" (2.00mm) pitch, 2-row layout, through-hole solder termination, push-pull fastening, gold-plated mating contacts, and -55°C to 125°C operating temperature range. They are functionally equivalent for board-to-board and cable connector applications.

Q: What are the differences between the two Samtec substitute parts?

A: MMS-116-01-F-DV and MMS-116-01-S-DV differ in contact finish thickness on the mating surface (3.00µin vs. 30.0µin) and insulation material composition. Both maintain the same electrical and mechanical specifications required for substitution.

Q: Are there any mechanical compatibility concerns when switching between these parts?

A: No. All three parts share identical pitch (0.079"), row spacing (0.079"), insulation height (0.175"), and mounting type (through-hole). PCB footprints and mating plug interfaces are compatible across all three part numbers.

Q: Do all substitute parts have the same current and voltage ratings?

A: The Molex 0791077265 is rated at 1A and 125V. The Samtec parts are rated at 3.9A per contact with no specified voltage rating in the provided data. Verify voltage requirements for your specific application before selection.

Q: Are all parts RoHS and export compliant?

A: Yes. All three parts are ROHS3 compliant and classified as EAR99 for export purposes, with matching HTSUS codes (8536.69.4040).
