Key Parameters

Substitute Part Grouping Explanation

The Harwin Inc. M22-7140342 qualifies as a substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle
• Number of positions: 6
• Pitch - mating: 0.079" (2.00mm)
• Number of rows: 2
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Through hole
• Termination: Solder
• Contact type: Female socket
• Contact finish - mating: Gold
• Fastening type: Push-pull
• Style: Board to board or cable
• RoHS3 compliance

These parameters establish mechanical and electrical compatibility for direct substitution in applications requiring a 6-position, 2.00mm pitch receptacle connector with gold-plated mating contacts and push-pull fastening.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791077202 and Harwin M22-7140342 are active production components with ROHS3 compliance and REACH unaffected status. The Harwin M22-7140342 provides higher current capacity (2A versus 1A) and higher voltage rating (500VAC versus 125V), making it suitable for applications requiring enhanced electrical performance. The Molex part maintains a wider operating temperature range (-55°C to 125°C versus -40°C to 105°C). Selection between these parts should be based on specific application electrical requirements and temperature operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M22-7140342 directly replace the Molex 0791077202?

A: Yes. Both connectors share identical mechanical specifications: 6 positions, 0.079" (2.00mm) pitch, 2-row configuration, through-hole mounting, solder termination, and push-pull fastening. The gold-plated mating contacts and female socket configuration are identical.

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

A: The Harwin M22-7140342 has higher electrical ratings (2A current, 500VAC voltage) compared to the Molex part (1A, 125V). The Molex 0791077202 operates across a wider temperature range (-55°C to 125°C versus -40°C to 105°C). The Harwin part uses Liquid Crystal Polymer insulation while the Molex uses thermoplastic glass-filled material.

Q: Are both parts compliant with industry standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8536.69.4040). Both have MSL rating of 1 (Unlimited moisture sensitivity).

Q: Which connector should I select for my application?

A: Selection depends on electrical requirements. If your application requires currents above 1A or voltages above 125V, the Harwin M22-7140342 is appropriate. If your application operates below -40°C, the Molex 0791077202 with its extended lower temperature limit is required.

Q: Are there any mechanical compatibility concerns?

A: No. Both connectors feature identical pitch spacing (0.079" mating and row spacing), through-hole mounting configuration, and push-pull fastening. PCB layout and mating interface are compatible.
