C&K 7101MHAV2ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101MHAV2ME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features a standard round actuator with epoxy-sealed PC pin termination, suitable for applications requiring reliable on-on switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101MHAV2ME is determined by strict alignment with the following critical parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage rating: 120V AC minimum, 28V DC
• Mounting type: Panel Mount, Right Angle, Vertical
• Actuator type: Standard Round
• Actuator length: 5.08mm
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Operating temperature range: -30°C ~ 85°C

Two substitute categories are identified:

Direct Equivalent: C&K 7101MHAV2SE matches all critical parameters and represents the active production equivalent within the same manufacturer series.

Cross-Manufacturer Substitutes: E-Switch 100SP1T2B1M7QEH and Grayhill Inc. 34ASP12B1M7QT meet all electrical and mechanical interface requirements, with documented differences in electrical life cycles noted in the parameter comparison.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: C&K 7101MHAV2SE is the direct equivalent for the obsolete 7101MHAV2ME. This part maintains identical electrical and mechanical specifications, including the 100,000-cycle electrical life rating. The 7101MHAV2SE is in active production status with ROHS3 compliance and REACH affected designation.

Secondary Recommendations: E-Switch 100SP1T2B1M7QEH and Grayhill Inc. 34ASP12B1M7QT are functionally compatible cross-manufacturer substitutes. Both parts meet all critical electrical and mechanical interface requirements. The primary distinction is reduced electrical life (40,000 cycles versus 100,000 cycles), which must be evaluated against application duty cycle requirements. Both parts maintain ROHS3 compliance and are in active production.

Compliance Considerations: All substitute parts meet RoHS requirements. The C&K 7101MHAV2SE carries REACH affected status, while E-Switch and Grayhill parts are REACH unaffected. Selection should account for supply chain compliance requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7101MHAV2SE directly replace the 7101MHAV2ME without circuit modification?

A: Yes. The 7101MHAV2SE is the direct equivalent with identical electrical ratings (5A at 120V AC, 28V DC), mechanical interface (panel mount with 1/4-40 bushing thread and 6.35mm circular cutout), and termination style (PC pin). No circuit or panel modifications are required.

Q: What is the significance of the 100,000-cycle versus 40,000-cycle electrical life difference?

A: Electrical life indicates the number of switching cycles the contact can withstand before degradation. The 7101MHAV2ME and 7101MHAV2SE are rated for 100,000 cycles, while E-Switch and Grayhill substitutes are rated for 40,000 cycles. Applications with high switching frequency should evaluate whether the reduced cycle rating is acceptable for the intended duty cycle.

Q: Are the E-Switch and Grayhill parts mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications: panel mount configuration, 5.08mm standard round actuator, 1/4-40 bushing thread, and 6.35mm circular panel cutout. Physical installation and panel integration are identical.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant designations?

A: ROHS3 refers to the third iteration of the Restriction of Hazardous Substances directive with updated substance restrictions. The C&K 7101MHAV2SE carries the RoHS Compliant designation, indicating compliance with the directive but potentially under an earlier version. Verify specific substance restrictions against your application requirements.

Q: Does REACH affected status impact part selection?

A: REACH affected status indicates the part contains substances of very high concern (SVHC) listed under the REACH regulation. The C&K 7101MHAV2SE is REACH affected, while E-Switch and Grayhill parts are REACH unaffected. Selection depends on end-use application location and regulatory requirements.

Q: Can these parts be used in applications rated for 125V AC instead of 120V AC?

A: The Grayhill 34ASP12B1M7QT is rated for 125V AC, making it suitable for 125V applications. The C&K and E-Switch parts are rated for 120V AC. Verify application voltage requirements before selection.
