Key Parameters

Substitute Part Grouping Explanation

The M80-8400245 qualifies as a direct substitute for the M80-8940205 based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Both are 2-position receptacle connectors with female socket contacts
• Pitch Specification: Identical 0.079" (2.00mm) mating pitch ensures mechanical compatibility with corresponding plug connectors
• Mounting & Termination: Both utilize through-hole PCB mounting with solder termination
• Fastening Mechanism: Both employ locking ramp fastening
• Contact Material & Finish: Both feature beryllium copper contacts with gold plating on mating surfaces
• Insulation Properties: Both meet UL94 V-0 flammability rating and operate across -55°C ~ 125°C temperature range
• Series Compatibility: Both belong to the Datamate L-Tek series

The primary distinction is product status: M80-8940205 is obsolete while M80-8400245 is active, with improved compliance and higher voltage rating capability.

Parameter Comparison

Engineering Selection Recommendations

The M80-8400245 is the appropriate substitute for the obsolete M80-8940205 based on the following engineering criteria:

Product Status & Availability: M80-8400245 is active and currently in production, ensuring long-term availability and supply chain continuity. The M80-8940205 is obsolete and subject to inventory depletion.

Regulatory Compliance: M80-8400245 achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The M80-8940205 is RoHS non-compliant, presenting regulatory risk in new designs and procurement.

Electrical Performance: M80-8400245 provides 800V voltage rating compared to 120V for M80-8940205, offering enhanced electrical capability for applications requiring higher voltage tolerance.

Mechanical Compatibility: Both connectors maintain identical pitch, mounting type, fastening mechanism, and stacking heights, ensuring direct PCB layout compatibility and mating interface consistency.

Material Specification: M80-8400245 utilizes polyamide (PA46) nylon 4/6 glass-filled insulation versus polyester in the original part, providing improved thermal and mechanical properties while maintaining the same operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can M80-8400245 directly replace M80-8940205 in existing PCB designs?

A: Yes. Both connectors share identical pitch (0.079"), mounting type (through-hole), fastening mechanism (locking ramp), and stacking heights. PCB footprints and mating interface specifications are compatible. The primary difference is contact post length (0.126" vs 0.051"), which does not affect PCB mounting compatibility.

Q: What is the significance of the voltage rating difference (120V vs 800V)?

A: The M80-8400245 provides higher voltage rating capability. For applications operating at or below 120V, both parts are functionally equivalent. For applications requiring higher voltage tolerance, M80-8400245 offers superior electrical performance margin.

Q: Does the insulation material change affect thermal performance?

A: Both parts operate across the identical temperature range (-55°C ~ 125°C) and maintain UL94 V-0 flammability rating. The polyamide (PA46) nylon 4/6 material in M80-8400245 provides improved mechanical properties compared to polyester while maintaining thermal specifications.

Q: What is the impact of RoHS compliance status?

A: M80-8400245 is ROHS3 compliant, meeting current environmental regulations for new designs and procurement. M80-8940205 is RoHS non-compliant and may face restrictions in regulated markets or applications subject to environmental compliance requirements.

Q: Are there packaging differences between these parts?

A: M80-8940205 packaging is not specified in available data. M80-8400245 is supplied in tube packaging. Confirm packaging requirements with procurement specifications for your application.

Q: How do the contact post lengths differ and does this matter?

A: M80-8940205 has 0.051" (1.30mm) contact post length while M80-8400245 has 0.126" (3.20mm). Both are through-hole solder termination connectors. The longer post in M80-8400245 provides additional solder joint engagement, potentially improving mechanical robustness of the solder connection.
