Key Parameters

Substitute Part Grouping Explanation

The M80-8400745 qualifies as a direct substitute for the M80-8940705 based on the following critical parameters:

• Identical manufacturer (Harwin Inc.) and series (Datamate L-Tek)
• Matching connector type (Receptacle), contact type (Female Socket), and number of positions (7)
• Identical mating pitch (0.079" / 2.00mm)
• Identical mounting type (Through Hole) and termination method (Solder)
• Matching contact finish (Gold) and contact material (Beryllium Copper)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical material flammability rating (UL94 V-0)
• Identical fastening type (Locking Ramp)
• Identical number of rows (1)

The M80-8400745 is currently in active production status, providing a viable replacement for the obsolete M80-8940705.

Parameter Comparison

Engineering Selection Recommendations

The M80-8400745 is the recommended substitute for the obsolete M80-8940705. Key advantages include:

• Active production status ensures long-term availability and supply chain continuity
• ROHS3 compliance versus non-compliant status of the original part, meeting current regulatory requirements
• Higher voltage rating (800V versus 120V) provides enhanced electrical performance margin
• Polyamide insulation material offers improved mechanical and thermal properties compared to polyester
• Longer contact post length (0.126" versus 0.051") accommodates varied PCB thickness applications
• Identical mechanical and electrical interface parameters ensure direct form-fit-function compatibility

Frequently Asked Questions (FAQ)

Q: Can M80-8400745 directly replace M80-8940705 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079" / 2.00mm), number of positions (7), mounting type (through hole), contact configuration (female socket), and fastening mechanism (locking ramp). The longer contact post on M80-8400745 accommodates standard PCB thickness variations without compatibility issues.

Q: What is the significance of the voltage rating difference?

A: The M80-8400745 operates at 800V versus 120V for the M80-8940705. This higher rating provides additional electrical performance margin and does not restrict application in circuits designed for the original 120V specification.

Q: How does the insulation material change affect performance?

A: M80-8400745 uses polyamide (PA46) nylon 4/6 glass-filled insulation versus polyester glass-filled in the original part. Polyamide offers superior mechanical strength, thermal stability, and chemical resistance, making it suitable for demanding automotive and military applications.

Q: Is RoHS compliance a critical factor for substitution?

A: The M80-8400745 is ROHS3 compliant while the M80-8940705 is non-compliant. For new designs and applications subject to RoHS regulations, M80-8400745 is the appropriate selection. For legacy system maintenance, compatibility depends on specific regulatory requirements.

Q: What packaging options are available?

A: M80-8400745 is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes.
