Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101MDAV2ME is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• 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 ~ 85°C

Electrical Performance Criteria:

• Current rating: 5A (AC/DC) minimum
• Voltage rating - AC: 120V minimum
• Voltage rating - DC: 28V minimum

Substitute parts are grouped into two categories:

Direct Equivalent (Same Manufacturer):

• 7101MDAV2SE (C&K): Identical electrical and mechanical specifications with active product status

Similar Alternatives (Different Manufacturers):

• 100SP1T2B1M7QEH and 100SP1T2B3M7QEH (E-Switch): Meet all primary compatibility criteria; actuator length differs at 5.08mm; electrical life rated at 40,000 cycles
• 34ASP12B1M7QT (Grayhill Inc.): Meets compatibility criteria; AC voltage rating 125V; electrical life 40,000 cycles
• 34ASP12B3M7RT (Grayhill Inc.): Meets mechanical compatibility; reduced electrical ratings (0.4VA at 20V); not suitable for primary application requirements
• A123P41DAV2B (Electroswitch): Meets mechanical compatibility; reduced electrical ratings (0.5VA at 28V); flatted actuator type differs from standard round

Parameter Comparison

Engineering Selection Recommendations

Recommended Primary Substitute: 7101MDAV2SE (C&K)

The 7101MDAV2SE is the direct equivalent replacement for the obsolete 7101MDAV2ME. It maintains identical electrical specifications (5A at 120V AC / 28V DC), mechanical configuration, and operating temperature range. The part is currently in active production status with 708 units in stock. RoHS compliance is maintained, though REACH status differs from the original part.

Secondary Substitutes for Full Electrical Compatibility:

100SP1T2B1M7QEH and 100SP1T2B3M7QEH (E-Switch) are functionally compatible alternatives that meet all primary electrical and mechanical requirements. Both parts maintain 5A current rating at 120V AC / 28V DC with identical mounting and termination specifications. The actuator length is reduced to 5.08mm compared to the original 6.86mm, and electrical life is rated at 40,000 cycles versus 100,000 cycles. Both parts are ROHS3 compliant and REACH unaffected.

34ASP12B1M7QT (Grayhill Inc.) provides full electrical compatibility with a slightly elevated AC voltage rating of 125V. Mechanical compatibility is maintained with identical mounting, termination, and panel cutout specifications. Electrical life is 40,000 cycles. This part is ROHS3 compliant and REACH unaffected.

Limited Compatibility Alternatives:

34ASP12B3M7RT and A123P41DAV2B do not meet the primary electrical requirements of the original specification. 34ASP12B3M7RT is rated for only 0.4VA at 20V AC/DC, and A123P41DAV2B is rated for 0.5VA at 28V DC. These parts are suitable only for low-power applications and should not be used as direct replacements for the 7101MDAV2ME in standard 5A applications.

Frequently Asked Questions (FAQ)

Q: Can the 7101MDAV2SE be used as a direct replacement for the 7101MDAV2ME?

A: Yes. The 7101MDAV2SE is electrically and mechanically identical to the 7101MDAV2ME. Both parts feature SPDT configuration, 5A current rating at 120V AC and 28V DC, identical mounting and termination specifications, and the same operating temperature range. The primary difference is product status: 7101MDAV2SE is active production while 7101MDAV2ME is obsolete.

Q: What is the impact of reduced actuator length in E-Switch alternatives?

A: The E-Switch models 100SP1T2B1M7QEH and 100SP1T2B3M7QEH feature a 5.08mm actuator length compared to the original 6.86mm. This reduction may affect panel aesthetics and operator feel but does not impact electrical performance or mechanical mounting compatibility. Panel cutout dimensions remain identical at 6.35mm circular diameter.

Q: Are there electrical performance differences between the recommended substitutes?

A: The primary electrical difference is electrical life rating. The original 7101MDAV2ME and its direct equivalent 7101MDAV2SE are rated for 100,000 cycles. E-Switch and Grayhill alternatives are rated for 40,000 cycles. All recommended substitutes maintain the required 5A current rating and voltage specifications for standard applications.

Q: What compliance certifications should be verified for substitute selection?

A: All recommended substitutes maintain RoHS compliance. REACH status varies: the original part is REACH Unaffected, while the direct equivalent 7101MDAV2SE is REACH Affected. E-Switch and Grayhill alternatives are REACH Unaffected. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Why are 34ASP12B3M7RT and A123P41DAV2B not suitable replacements?

A: These parts do not meet the electrical requirements of the original specification. 34ASP12B3M7RT is rated for 0.4VA at 20V AC/DC, and A123P41DAV2B is rated for 0.5VA at 28V DC. Both are significantly below the required 5A rating and are suitable only for low-power control circuits. Use these parts only in applications with reduced electrical requirements.

Q: What packaging considerations apply to these substitutes?

A: The original 7101MDAV2ME packaging is not specified. E-Switch and Grayhill alternatives are supplied in bulk packaging. Verify packaging requirements and minimum order quantities with your supplier before procurement.
