Molex 0791077252 Equivalent & Substitute Parts

Part Overview

The Molex 0791077252 is a 6-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

The Harwin Inc. M22-7140342 is identified as a manufacturer-recommended substitute for the Molex 0791077252. Substitution compatibility is determined by the following critical parameters:

Matching Parameters:

• Connector type: Receptacle with female socket contacts
• 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
• Fastening type: Push-pull
• Contact finish - mating: Gold
• Insulation color: Black
• Contact shape: Square
• Contact material: Phosphor bronze
• Style: Board to board or cable
• RoHS status: ROHS3 compliant
• Moisture sensitivity level: 1 (Unlimited)

These parameters establish mechanical and electrical interchangeability for the primary connector interface. Variations in secondary parameters such as current rating, voltage rating, and operating temperature range do not preclude substitution but must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791077252 and Harwin M22-7140342 are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings. The Harwin substitute provides higher current capacity (2A versus 1A) and higher voltage rating (500VAC versus 125V), representing enhanced electrical performance characteristics. The operating temperature range of the Molex part extends to -55°C, while the Harwin part operates to -40°C minimum. Contact post length differs by 0.019" (0.49mm), and insulation height varies by 0.002" (0.05mm). Selection between these parts should be based on application-specific electrical requirements and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0791077252 and Harwin M22-7140342 mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), row configuration (2 rows), position count (6), and fastening type (push-pull). Insulation height and contact post length variations are minimal and do not prevent mechanical mating.

Q: What are the key electrical differences between these parts?

A: The Harwin M22-7140342 is rated for 2A at 500VAC, compared to the Molex part rated for 1A at 125V. Applications requiring higher current or voltage should use the Harwin substitute.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity).

Q: What is the temperature operating range difference?

A: The Molex 0791077252 operates from -55°C to 125°C, while the Harwin M22-7140342 operates from -40°C to 105°C. Applications requiring operation below -40°C require the Molex part.

Q: Are there packaging differences?

A: The Molex part is supplied in standard packaging, while the Harwin M22-7140342 is supplied in tube packaging.
