Parameter Comparison

Engineering Selection Recommendations

Primary Component - 34CMSP12B1M2RT (Grayhill Inc.): This component maintains Active product status with RoHS compliance certification. Selection is appropriate for applications requiring the specified 0.4VA/20V electrical characteristics with standard panel mount integration.

Substitute Option 1 - 200MSP1T2B1M2QE (E-Switch): This substitute provides equivalent mechanical compatibility with enhanced electrical performance (3A/120V AC, 28V DC). The component maintains Active product status and ROHS3 compliance. Electrical life rating remains at 30,000 cycles. This substitute is suitable for applications where higher voltage or current capacity is required within the same form factor.

Substitute Option 2 - T101MHCGE (C&K): This substitute provides equivalent mechanical compatibility with enhanced electrical performance (3A/120V AC, 28V DC) and extended electrical life rating of 60,000 cycles compared to 30,000 cycles for the primary component. The component maintains Active product status and ROHS3 compliance. REACH status is listed as Affected for this component. This substitute is suitable for applications requiring extended operational life or higher electrical ratings.

All three components share identical mechanical interfaces, panel cutout dimensions, bushing threads, and termination styles, ensuring direct form-factor compatibility in panel mount applications.

Frequently Asked Questions (FAQ)

Q: Can the 200MSP1T2B1M2QE substitute directly for the 34CMSP12B1M2RT in all applications?

A: Direct substitution is mechanically compatible due to identical panel cutout dimensions (4.95mm Dia), bushing thread (10-48), actuator type and length (5.33mm), and termination style (PC Pin). The substitute provides higher electrical ratings (3A/120V AC versus 0.4VA/20V). Substitution is valid for applications where the original electrical specifications are not exceeded and the higher ratings do not create design conflicts.

Q: What is the difference between the E-Switch and C&K substitute options?

A: Both 200MSP1T2B1M2QE (E-Switch) and T101MHCGE (C&K) provide identical electrical ratings (3A/120V AC, 28V DC) and mechanical compatibility. The primary difference is electrical life rating: E-Switch provides 30,000 cycles while C&K provides 60,000 cycles. The C&K component has REACH status listed as Affected, whereas the primary component and E-Switch substitute have REACH status as Unaffected.

Q: Are all three components RoHS compliant?

A: The primary component 34CMSP12B1M2RT is RoHS Compliant. Both substitute parts (200MSP1T2B1M2QE and T101MHCGE) are ROHS3 Compliant, which represents an updated compliance standard. All three components maintain regulatory compliance for RoHS requirements.

Q: What are the moisture sensitivity implications for these components?

A: All three components share Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or installation. This classification applies uniformly across the primary component and both substitutes.

Q: Can I use a substitute with higher voltage and current ratings in a low-power application?

A: Yes. The substitute components with higher electrical ratings (3A/120V) are suitable for applications originally specified for 0.4VA/20V operation. The higher ratings provide design margin and do not create incompatibility in lower-power applications. Mechanical form factor remains identical, ensuring panel mount compatibility.

Q: What is the significance of the different electrical life ratings?

A: The primary component and E-Switch substitute are rated for 30,000 electrical cycles. The C&K substitute is rated for 60,000 cycles, providing double the operational life. Selection between 30,000 and 60,000 cycle ratings depends on application duty cycle requirements and expected service life.

Q: Are there any packaging differences between these components?

A: The primary component 34CMSP12B1M2RT is packaged as indicated in the specification. The E-Switch substitute 200MSP1T2B1M2QE is packaged in Bulk. The C&K substitute T101MHCGE is packaged in Bulk. Packaging differences do not affect electrical or mechanical compatibility.
