Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0791077207 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Must be a receptacle with female socket contacts
• Position Count & Pitch: Must maintain 16 positions at 0.079" (2.00mm) mating pitch with 2-row configuration
• Mounting & Termination: Must support through-hole solder termination with push-pull fastening
• Mating Contact Finish: Must feature gold-plated mating contacts
• Compliance: Must maintain ROHS3 compliance and EAR99 classification

The Harwin Inc. M22-7140842 qualifies as a manufacturer-recommended substitute based on these core parameters. Both components share identical position count, pitch spacing, mounting methodology, and fastening approach. Variations in secondary parameters such as operating temperature range, current rating, voltage rating, and insulation material do not preclude substitution when the primary electrical and mechanical interfaces are preserved.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791077207 and Harwin M22-7140842 maintain Active product status and full ROHS3 compliance with EAR99 classification. The Harwin substitute provides enhanced electrical performance characteristics, including higher current rating (2A versus 1A) and elevated voltage rating (500VAC versus 125V). The Harwin component features UL94 V-0 material flammability rating, providing additional safety certification.

The operating temperature range of the Molex component (-55°C to 125°C) exceeds that of the Harwin substitute (-40°C to 105°C). Applications requiring the full lower temperature specification of the Molex part should not substitute with the Harwin alternative. For applications operating within the -40°C to 105°C envelope, the Harwin M22-7140842 provides equivalent or superior electrical performance.

Both components utilize identical mating pitch, row configuration, and mechanical interface specifications, ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M22-7140842 be used as a direct replacement for the Molex 0791077207?

A: Yes, for applications operating within the -40°C to 105°C temperature range. Both connectors share identical 16-position, 0.079" (2.00mm) pitch configuration with 2-row layout, through-hole solder termination, and push-pull fastening. PCB footprints are mechanically compatible. Applications requiring operation below -40°C must retain the Molex component.

Q: What are the key differences between these two connectors?

A: Primary differences include operating temperature range (Molex: -55°C to 125°C; Harwin: -40°C to 105°C), current rating (Molex: 1A; Harwin: 2A), voltage rating (Molex: 125V; Harwin: 500VAC), and insulation material (Molex: Thermoplastic Glass Filled; Harwin: Liquid Crystal Polymer). The Harwin component includes UL94 V-0 flammability certification.

Q: Are the mating contacts compatible between these two connector series?

A: Yes. Both connectors feature gold-plated mating contacts with identical 0.079" (2.00mm) pitch spacing and 2-row configuration. Mating interface compatibility is preserved.

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

A: The Molex component uses thermoplastic glass-filled insulation, while the Harwin uses Liquid Crystal Polymer (LCP). Both materials are suitable for through-hole solder applications. LCP provides enhanced dimensional stability and chemical resistance. Material selection should align with specific application environmental requirements.

Q: Can these connectors be used interchangeably in existing designs?

A: Mechanical and electrical interface compatibility is confirmed for applications within the overlapping operating temperature range (-40°C to 105°C). Design validation should confirm that the substitute component's electrical ratings (2A, 500VAC) meet or exceed application requirements. No PCB redesign is required.
