• E-Switch 100SP1T2B3M2QEH: Matches all primary electrical and mechanical parameters
• E-Switch 100SP1T1B1M2REH: Lower electrical ratings (0.4VA at 20V); not electrically equivalent

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents: E-Switch 100SP1T1B3M2QEH and E-Switch 100SP1T2B3M2QEH are electrically and mechanically equivalent to the C&K 7101MPYCQE. Both parts meet the 5A/120V AC and 28V DC ratings, share identical panel mount specifications, and maintain ROHS3 compliance. Selection between these two E-Switch variants depends on actuator length requirements: 100SP1T1B3M2QEH features 10.41mm actuator length, while 100SP1T2B3M2QEH features 5.08mm actuator length (matching the original C&K part).

Non-Equivalent Part: E-Switch 100SP1T1B1M2REH is not electrically equivalent. Its 0.4VA rating at 20V AC/DC falls below the required 5A/120V AC specification and is unsuitable for direct substitution in applications requiring the full electrical capacity of the 7101MPYCQE.

Compliance Considerations: All equivalent substitute parts maintain ROHS3 compliance and active product status, ensuring regulatory alignment and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100SP1T1B1M2REH replace the C&K 7101MPYCQE? A: No. The 100SP1T1B1M2REH is rated for 0.4VA at 20V, which is insufficient for applications requiring 5A at 120V AC. This part is not electrically equivalent.

Q: What is the difference between E-Switch 100SP1T1B3M2QEH and 100SP1T2B3M2QEH? A: Both parts are electrically identical with matching 5A/120V AC ratings and panel mount specifications. The primary difference is actuator length: 100SP1T1B3M2QEH has a 10.41mm actuator, while 100SP1T2B3M2QEH has a 5.08mm actuator matching the original C&K part.

Q: Are the substitute parts panel-mount compatible with the original design? A: Yes. Both E-Switch equivalents share identical panel cutout dimensions (Circular 6.35mm Dia) and bushing thread (1/4-40), ensuring mechanical compatibility with existing panel installations.

Q: Do the substitute parts meet the same compliance standards? A: Yes. All equivalent substitute parts are ROHS3 compliant and maintain active product status, matching the regulatory profile of the C&K 7101MPYCQE.

Q: What is the electrical life difference between the main part and substitutes? A: The C&K 7101MPYCQE is rated for 100,000 cycles, while E-Switch equivalents are rated for 40,000 cycles. Application duty cycle requirements should be evaluated accordingly.
