Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101MDAV2LE are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit configuration (SPDT required)
• Switch function (On-On operation)
• Mounting type (Panel Mount, Right Angle, Vertical)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread (1/4-40)
• Operating temperature range (-30°C to 85°C minimum)

Substitutes are categorized as direct equivalents or similar alternatives based on how closely they match the electrical ratings (current and voltage) and mechanical specifications of the original part.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

The C&K 7101MDAV2RE is the direct equivalent to the obsolete 7101MDAV2LE. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), mechanical configuration, and panel cutout specifications. The 7101MDAV2RE is currently in active production status and maintains full compatibility with the original design. This part carries RoHS compliance certification and is the preferred choice for direct replacement.

Alternative Substitutes (Conditional Use):

The E-Switch 100SP1T2B1M7QEH and 100SP1T2B3M7QEH are functionally compatible alternatives with matching electrical ratings and mechanical mounting. Both are active products with ROHS3 compliance. The primary design consideration is the reduced actuator length (5.08mm versus 6.86mm on the original), which may affect panel aesthetics but does not impact electrical function.

The Grayhill 34ASP12B1M7QT maintains full electrical and mechanical compatibility with 5A at 125V AC rating, exceeding the original 120V specification. This part is suitable for applications requiring higher AC voltage margin.

The Grayhill 34ASP12B3M7RT and Electroswitch A123P41DAV2B are lower-power alternatives with reduced current and voltage ratings. These parts are suitable only for applications where the original 5A / 120V specification is not required.

Frequently Asked Questions (FAQ)

Q: Can the 7101MDAV2RE directly replace the obsolete 7101MDAV2LE without design modification?

A: Yes. The 7101MDAV2RE is a direct equivalent with identical electrical ratings, mechanical configuration, panel cutout dimensions, and bushing thread specifications. No design changes are required.

Q: What is the primary difference between the E-Switch 100SP1T2B1M7QEH and the original C&K part?

A: The E-Switch part has a shorter actuator length (5.08mm versus 6.86mm). Electrical ratings and mechanical mounting are identical. Panel appearance may differ slightly due to actuator height variation.

Q: Are the Grayhill 34ASP12B3M7RT and Electroswitch A123P41DAV2B suitable replacements for the original application?

A: These parts have significantly reduced current and voltage ratings (0.4VA to 0.5VA at 20V to 28V). They are suitable only for applications where the original 5A / 120V specification is not required. Verify application requirements before substitution.

Q: What compliance certifications should I verify for substitute parts?

A: All listed substitutes carry RoHS compliance (either RoHS or ROHS3). Verify REACH status and ECCN classification for your specific supply chain and regulatory requirements. All listed parts carry EAR99 ECCN classification.

Q: Does the operating temperature range differ among substitute parts?

A: The Electroswitch A123P41DAV2B extends the upper temperature limit to 90°C (versus 85°C on the original). All other substitutes maintain the -30°C to 85°C range. Verify temperature requirements for your application environment.

Q: How does electrical life cycle rating affect part selection?

A: The original 7101MDAV2LE and direct equivalent 7101MDAV2RE are rated for 100,000 cycles. Alternative substitutes range from 40,000 to 60,000 cycles. Select based on application duty cycle requirements and expected service life.
