Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0791077263 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Must be a receptacle with female socket contacts
• Position Count & Pitch: Must maintain 28 positions at 0.079" (2.00mm) mating pitch with 2-row configuration and 0.079" row spacing
• Mounting & Termination: Must support through-hole solder termination with push-pull fastening
• Mating Contact Finish: Must feature gold-plated mating contacts
• Operating Environment: Must support -55°C to 125°C temperature range
• Compliance: Must maintain ROHS3 compliance

The Samtec MMS-114-01-H-DV meets all critical substitution criteria. Both connectors share identical mechanical pitch, position count, row configuration, mounting method, and environmental specifications. Both are ROHS3 compliant and support the same fastening mechanism.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791077263 and Samtec MMS-114-01-H-DV are active production parts with ROHS3 compliance and EAR99 classification. Selection between these parts should be based on:

• Availability: Molex 0791077263 has 967 units in stock; Samtec MMS-114-01-H-DV has 828 units in stock
• Packaging: Molex is supplied in standard packaging; Samtec is supplied in bulk packaging
• Contact Post Specifications: Molex features 0.075" (1.91mm) contact length with tin finish; Samtec features 0.115" (2.92mm) contact length with gold finish
• Current Rating Variance: Molex is rated at 1A per contact; Samtec is rated at 3.9A per contact
• Insulation Material: Molex uses thermoplastic glass-filled material; Samtec uses liquid crystal polymer (LCP)

Both parts maintain identical mechanical and electrical compatibility for standard applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-114-01-H-DV directly replace the Molex 0791077263 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079"), position count (28), row configuration (2 rows), mounting method (through-hole), and fastening mechanism (push-pull). Mechanical and electrical compatibility is maintained for standard board-to-board and cable applications.

Q: What are the differences in contact specifications between these two parts?

A: The Molex part features 0.075" contact post length with tin finish and 1A current rating per contact. The Samtec part features 0.115" contact post length with gold finish and 3.9A current rating per contact. Applications requiring higher current capacity should specify the Samtec part.

Q: Are both parts compliant with RoHS regulations?

A: Yes. Both the Molex 0791077263 and Samtec MMS-114-01-H-DV are ROHS3 compliant and carry EAR99 export classification.

Q: What is the difference in insulation material between these connectors?

A: The Molex part uses thermoplastic glass-filled insulation material. The Samtec part uses liquid crystal polymer (LCP) insulation material. Both materials support the identical -55°C to 125°C operating temperature range.

Q: How do packaging differences affect component selection?

A: The Molex part is supplied in standard packaging, while the Samtec part is supplied in bulk packaging. Bulk packaging may offer cost advantages for high-volume production runs but requires verification of internal packaging specifications for automated assembly compatibility.
