Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 34CMDP12B2M2RT are identified based on strict adherence to the following critical parameters:

Circuit Configuration Match: All substitute parts must be DPDT (Double Pole Double Throw) with On-On switch function to maintain electrical compatibility with the original design.

Mounting and Termination: All substitutes must feature through-hole mounting with PC pin termination to ensure direct compatibility with existing printed circuit board layouts and assembly processes.

Electrical Ratings: Substitute parts must meet or exceed the voltage and current specifications of the original part. The 34CMDP12B2M2RT operates at 0.4VA with 20V AC/DC ratings. Substitutes with higher voltage or current ratings remain compatible for applications requiring the original specifications.

Physical Form Factor: Actuator type and length are important for panel cutout compatibility and user interface consistency. The standard round actuator at 5.33mm length defines the mechanical envelope.

Compliance and Environmental: All substitutes must maintain ROHS3 compliance and operate within the -30°C to 85°C temperature range to ensure regulatory and environmental compatibility.

The following substitute parts meet these criteria:

• 200MDP1T2B2M2RE (E-Switch): Exact electrical and mechanical match to the original part
• 200MDP1T2B2M2QE (E-Switch): Higher current and voltage ratings (3A, 120V AC) with identical mechanical specifications
• B22JP (NKK Switches): Matching electrical ratings with enhanced electrical life (50,000 cycles) and slightly higher actuator length (6.30mm)

Engineering Selection Recommendations

Direct Equivalent (Preferred for Drop-In Replacement):

The 200MDP1T2B2M2RE from E-Switch is the direct electrical and mechanical equivalent to the 34CMDP12B2M2RT. This part maintains identical current ratings (0.4VA), voltage specifications (20V AC/DC), actuator dimensions (5.33mm), and electrical life (30,000 cycles). Both parts are ROHS3 compliant with REACH unaffected status. This substitute is suitable for applications requiring no design modifications.

Higher-Capacity Alternative:

The 200MDP1T2B2M2QE from E-Switch provides enhanced electrical performance with 3A current capacity and 120V AC rating (28V DC). This part is applicable to applications where the original 0.4VA specification is insufficient or where future design margin is required. The identical mechanical form factor (5.33mm actuator) permits direct panel integration. ROHS3 compliance and REACH unaffected status are maintained.

Extended Electrical Life Option:

The B22JP from NKK Switches offers 50,000 electrical cycles compared to the 30,000 cycles of the original part, providing enhanced durability for high-cycle applications. This part matches the 0.4VA current rating and exceeds the voltage specification at 28V AC/DC. The actuator length is 6.30mm, which is 0.97mm longer than the original specification. This dimensional difference requires verification against panel cutout tolerances before selection. ROHS3 compliance and REACH unaffected status are maintained.

All substitute parts are Active in product status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 200MDP1T2B2M2QE be used as a direct replacement for the 34CMDP12B2M2RT?

A: Yes. The 200MDP1T2B2M2QE maintains identical mechanical specifications (5.33mm actuator length, through-hole mounting, PC pin termination) and circuit configuration (DPDT, On-On). The higher current (3A) and voltage (120V AC, 28V DC) ratings are backward compatible with applications designed for 0.4VA at 20V. No design modifications are required.

Q: What is the significance of the actuator length difference in the B22JP?

A: The B22JP features a 6.30mm actuator length compared to the 5.33mm standard. This 0.97mm difference affects the panel cutout clearance and user interface feel. Applications with tight panel tolerances or specific actuator travel requirements must account for this dimensional variation. Panel cutout compatibility should be confirmed before implementation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 200MDP1T2B2M2RE, 200MDP1T2B2M2QE, and B22JP are all ROHS3 compliant with REACH unaffected status, matching the regulatory compliance of the original 34CMDP12B2M2RT.

Q: What is the difference between the two E-Switch alternatives?

A: The 200MDP1T2B2M2RE is an exact electrical and mechanical match to the original part (0.4VA, 20V, 5.33mm actuator). The 200MDP1T2B2M2QE provides higher electrical capacity (3A, 120V AC) while maintaining identical mechanical specifications. Selection depends on whether the application requires the original specifications or benefits from enhanced electrical performance.

Q: Does the B22JP offer any performance advantages?

A: The B22JP provides extended electrical life at 50,000 cycles compared to 30,000 cycles in the original part, making it suitable for high-cycle switching applications. It also exceeds the voltage specification at 28V AC/DC. The primary consideration is the 6.30mm actuator length, which requires panel cutout verification.

Q: Are all parts available in bulk packaging?

A: Yes. All substitute parts are available in bulk packaging with confirmed inventory: 200MDP1T2B2M2RE (1,133 pcs), 200MDP1T2B2M2QE (1,146 pcs), and B22JP (1,098 pcs).

Q: What is the operating temperature range for all parts?

A: All parts operate within the -30°C to 85°C temperature range, ensuring compatibility across standard industrial and commercial applications.

Q: Can these switches be used interchangeably in the same circuit board design?

A: The 200MDP1T2B2M2RE and 200MDP1T2B2M2QE are direct mechanical and electrical interchanges with identical through-hole mounting and PC pin termination. The B22JP requires panel cutout verification due to the 6.30mm actuator length. All three maintain the same circuit configuration (DPDT, On-On) and termination style.
