Substitute Part Grouping Explanation

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

  • Connector Type: Both are receptacles
  • Number of Positions: Both feature 6 positions
  • Pitch - Mating: Both use 0.079" (2.00mm) pitch
  • Number of Rows: Both are 2-row configurations
  • Row Spacing - Mating: Both maintain 0.079" (2.00mm) spacing
  • Mounting Type: Both are through-hole mounted
  • Contact Type: Both use female socket contacts
  • Contact Finish - Mating: Both feature gold plating
  • Termination: Both use solder termination
  • Fastening Type: Both employ push-pull fastening

These parameters establish mechanical and electrical interchangeability for the primary mating interface. Differences in secondary specifications (operating temperature range, current rating, voltage rating, and insulation material) must be evaluated against specific application requirements.

Engineering Selection Recommendations

Both the Molex 0791077052 and Harwin M22-7140342 are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The Harwin M22-7140342 offers higher current capacity (2A versus 1A) and voltage rating (500VAC versus 125V), making it suitable for applications requiring enhanced electrical performance. The Molex 0791077052 supports a wider operating temperature range (-55°C to 125°C versus -40°C to 105°C), which may be critical for extreme environment applications. Selection should be based on the specific electrical and thermal requirements of the target application, with consideration for mechanical fit given the minor differences in insulation height (0.175" versus 0.173") and contact post length (0.118" versus 0.094").

Frequently Asked Questions (FAQ)

Q: Are the Molex 0791077052 and Harwin M22-7140342 mechanically compatible?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), row configuration (2 rows), and row spacing (0.079" / 2.00mm). Both use through-hole mounting with push-pull fastening and gold-plated mating contacts. Minor dimensional differences exist in insulation height and contact post length, which should be verified against PCB layout requirements.

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

A: The Harwin M22-7140342 provides higher current capacity (2A versus 1A) and voltage rating (500VAC versus 125V). The Molex 0791077052 supports a broader operating temperature range (-55°C to 125°C versus -40°C to 105°C). Application requirements determine which part is appropriate.

Q: Are both parts RoHS compliant?

A: Yes. Both the Molex 0791077052 and Harwin M22-7140342 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the packaging format for these connectors?

A: Both parts are supplied in tube packaging, suitable for automated assembly processes and manual component handling.

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

A: Mechanical interchangeability is established through matching pitch, row configuration, and mounting type. Electrical interchangeability depends on application requirements for current, voltage, and operating temperature. PCB layout verification is necessary due to minor dimensional variations.
