Key Parameters

Substitute Part Grouping Explanation

The M80-8400742 qualifies as a direct substitute for the M80-8940701 based on the following critical parameters:

• Connector Type & Position Count: Both are 7-position receptacles within the Datamate L-Tek series
• Pitch Specification: Identical 0.079" (2.00mm) mating pitch ensures mechanical and electrical compatibility
• Mounting Configuration: Both utilize through-hole solder termination with locking ramp fastening
• Contact Geometry: Circular beryllium copper contacts with gold mating finish in both designs
• Insulation Height & Stacking: Matching 0.202" (5.14mm) insulation height and 7.23mm/7.83mm mated stacking heights
• Operating Temperature: Identical -55°C to 125°C thermal range
• Material Compliance: Both meet UL94 V-0 flammability rating

The M80-8400742 represents an active production alternative to the obsolete M80-8940701, enabling continued system support and new production builds.

Parameter Comparison

Engineering Selection Recommendations

The M80-8400742 is the appropriate selection for applications currently using or requiring the M80-8940701. Key advantages include:

• Active Production Status: The M80-8400742 is in active production, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The substitute achieves ROHS3 compliance, addressing modern regulatory requirements that the obsolete part does not meet
• Identical Mechanical Interface: Matching pitch, mounting configuration, and stacking heights ensure direct PCB compatibility without redesign
• Equivalent Electrical Performance: Identical contact materials, finishes, and operating temperature range maintain functional equivalence
• Packaging: Available in tube packaging for production environments

Frequently Asked Questions (FAQ)

Q: Can M80-8400742 directly replace M80-8940701 on existing PCBs?

A: Yes. Both connectors share identical 0.079" (2.00mm) pitch, through-hole mounting footprint, and 0.202" (5.14mm) insulation height. No PCB redesign is required.

Q: What are the differences between these two connectors?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), insulation material (polyester glass-filled vs. polyamide nylon 4/6 glass-filled), contact post finish (tin-lead vs. tin), and contact post length (0.051" vs. 0.126"). These differences do not affect mechanical or electrical compatibility.

Q: Are there voltage or current rating differences?

A: The main part lists 120V voltage rating while the substitute lists 800V. Both parts do not specify current ratings in the provided data. The higher voltage rating of the substitute provides additional design margin.

Q: What is the impact of different insulation materials?

A: The M80-8400742 uses polyamide (PA46) nylon 4/6 glass-filled insulation compared to polyester glass-filled in the M80-8940701. Both materials meet UL94 V-0 flammability requirements and maintain identical operating temperature ranges and mechanical dimensions.

Q: Does the longer contact post on M80-8400742 affect compatibility?

A: No. The contact post length difference (0.051" vs. 0.126") does not impact mating compatibility. Both connectors maintain identical mated stacking heights of 7.23mm and 7.83mm.

Q: Is the packaging difference significant?

A: The M80-8400742 is supplied in tube packaging suitable for production automation. The M80-8940701 packaging is not specified. Tube packaging is standard for active production components and does not affect connector performance.
