Key Parameters

Substitute Part Grouping Explanation

Substitution for the M80-7531442 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Number of positions (14)
• Number of rows (2)
• Pitch specification (0.079" / 2.00mm mating pitch and row spacing)
• Mounting method (Through Hole)
• Contact type (Male Pin)
• Electrical ratings (2.2A per contact, 800V)
• Operating temperature range (-55°C ~ 125°C)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Latch Lock)
• Material specifications (Phosphor Bronze contacts, PPS insulation)
• Compliance certifications (UL94 V-0, ROHS3, REACH Unaffected)

The M80-7531445 meets all these criteria and is classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The M80-7531445 is the direct equivalent substitute for the obsolete M80-7531442. Both components are manufactured by Harwin Inc. within the Datamate L-Tek series and share identical electrical, mechanical, and environmental specifications.

The primary distinction is product status: M80-7531442 is obsolete, while M80-7531445 is active. This transition ensures continued availability and supply chain reliability for new designs and production runs.

Both parts maintain full compliance with ROHS3 and REACH requirements, carry UL94 V-0 flammability certification, and are rated for identical operating conditions across temperature, voltage, and current parameters. The connector geometry, contact configuration, and mating interface are functionally equivalent.

Frequently Asked Questions (FAQ)
