Molex 0791077206 Equivalent & Substitute Parts

Part Overview

The Molex 0791077206 is a 14-position receptacle connector from the Milli-Grid 79107 series, designed for board-to-board or cable applications. This through-hole mounted connector features 0.079" (2.00mm) pitch mating contacts with gold plating and is rated for 1A at 125V. The part is active in production and ROHS3 compliant, making it suitable for automotive, general purpose, and telecommunications applications. Identifying equivalent substitute parts is necessary when the primary part is unavailable or when design requirements necessitate alternative specifications within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0791077206 is based on strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 14 positions in 2-row configuration
• Mating Pitch: 0.079" (2.00mm) pitch requirement
• Mounting & Termination: Through-hole solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Finish: Gold-plated mating surface
• Regulatory Compliance: ROHS3 compliant status

The Harwin Inc. M22-7140742 meets these core substitution criteria. While certain parameters differ (operating temperature range, current/voltage ratings, insulation material), these variations remain within acceptable tolerances for equivalent component selection in rectangular connector applications.

Parameter Comparison

Engineering Selection Recommendations

The Harwin M22-7140742 is a qualified substitute for the Molex 0791077206 based on matching core connector specifications: 14-position receptacle configuration, 0.079" (2.00mm) pitch, through-hole solder termination, and push-pull fastening. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The M22-7140742 provides enhanced electrical performance with 2A current rating and 500VAC voltage rating compared to the original 1A/125V specification. The operating temperature range of -40°C ~ 105°C is narrower than the Molex part's -55°C ~ 125°C range; this difference must be evaluated against specific application requirements. The M22-7140742 uses Liquid Crystal Polymer (LCP) insulation material versus the Molex thermoplastic glass-filled insulation, with UL94 V-0 flammability rating providing enhanced material performance.

Selection between these parts should be based on application-specific temperature requirements, electrical load demands, and material performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M22-7140742 directly replace the Molex 0791077206 in existing designs?

A: Direct mechanical and electrical substitution is possible due to matching pitch (0.079"), position count (14), row configuration (2), and fastening type (push-pull). However, the narrower operating temperature range (-40°C ~ 105°C versus -55°C ~ 125°C) must be verified against application requirements before implementation.

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

A: Primary differences include operating temperature range, current/voltage ratings, insulation material composition, and flammability rating. The M22-7140742 offers higher electrical ratings (2A/500VAC) and UL94 V-0 material certification, while the Molex part supports extended low-temperature operation to -55°C.

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

A: Both the Molex 0791077206 and Harwin M22-7140742 are supplied in tube packaging, supporting equivalent handling and storage procedures.

Q: What compliance certifications apply to both parts?

A: Both connectors are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component applications.

Q: How do the contact post specifications differ?

A: The Molex part features 0.075" (1.91mm) contact post length with 74.8µin (1.90µm) tin finish thickness. The Harwin part specifies 0.094" (2.40mm) contact post length. These dimensional differences must be evaluated for PCB layout compatibility.
