• Actuator type must be Standard Round
• Actuator length must be 9.40mm
• Panel cutout dimensions must be Circular - 4.95mm Dia
• Bushing thread must be 10-48
• Termination style must be Solder Lug

Electrical Compatibility Requirements:

• Operating temperature range must encompass -30°C ~ 85°C
• Electrical life must be minimum 30,000 Cycles
• Current and voltage ratings must meet or exceed application requirements

Compliance Requirements:

• RoHS3 compliance status
• Product status must be Active

The substitute parts 200MDP3T1B1M1QEH and T203SHZQE satisfy all mechanical and functional parameters. Both parts feature higher current and voltage ratings, which provide operational margin in applications requiring the 34CMDP31B1M1RT specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - 34CMDP31B1M1RT (Grayhill Inc.): Select this part when the application circuit operates within 0.4VA at 20V AC/DC specifications. This part is the original design component with 817 units in current inventory and full ROHS3 compliance.

Substitute Selection - 200MDP3T1B1M1QEH (E-Switch): This substitute is suitable when the 34CMDP31B1M1RT is unavailable. The 200MDP3T1B1M1QEH provides identical mechanical interface and functional characteristics with enhanced electrical ratings (3A at 120V AC, 28V DC). This part maintains ROHS3 compliance and active production status with 877 units in inventory. The elevated current and voltage ratings provide operational margin for applications that may require future specification adjustments.

Substitute Selection - T203SHZQE (C&K): This substitute is suitable when both the 34CMDP31B1M1RT and 200MDP3T1B1M1QEH are unavailable. The T203SHZQE provides identical mechanical interface and functional characteristics with electrical ratings of 2A at 120V AC and 28V DC. This part maintains active production status with 878 units in inventory. Note that REACH status is listed as Affected for this part, requiring verification against specific regulatory requirements in the end application region.

All three parts share identical mechanical mounting characteristics, panel cutout dimensions, bushing thread specifications, and termination methods, ensuring direct physical interchangeability in panel mount applications.

Frequently Asked Questions (FAQ)

Q: Can the 200MDP3T1B1M1QEH replace the 34CMDP31B1M1RT in all applications?

A: The 200MDP3T1B1M1QEH is mechanically and functionally interchangeable with the 34CMDP31B1M1RT. Both parts feature identical DPDT On-Off-On configuration, panel mount design, 9.40mm actuator length, 4.95mm circular panel cutout, and 10-48 bushing thread. The 200MDP3T1B1M1QEH provides higher electrical ratings (3A versus 0.4VA, 120V AC versus 20V AC), which are compatible with applications designed for the original part.

Q: What is the difference between the 200MDP3T1B1M1QEH and T203SHZQE substitutes?

A: Both parts are mechanically identical to the 34CMDP31B1M1RT and to each other in terms of panel mount interface, actuator specifications, and termination style. The primary difference is current rating: the 200MDP3T1B1M1QEH is rated for 3A while the T203SHZQE is rated for 2A. Both operate at 120V AC and 28V DC. The T203SHZQE has REACH Affected status, while the 34CMDP31B1M1RT and 200MDP3T1B1M1QEH have REACH Unaffected status.

Q: Are all three parts ROHS3 compliant?

A: The 34CMDP31B1M1RT and 200MDP3T1B1M1QEH are ROHS3 compliant. The T203SHZQE is also ROHS3 compliant. All three parts meet RoHS3 requirements for hazardous substance restrictions.

Q: Do these parts require any special handling or storage considerations?

A: All three parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Can these switches be used in applications requiring higher current ratings than 0.4VA?

A: The 34CMDP31B1M1RT is specified for 0.4VA operation. If an application requires higher current capacity, the substitute parts 200MDP3T1B1M1QEH (3A) or T203SHZQE (2A) provide the necessary electrical margin while maintaining identical mechanical and functional characteristics.

Q: What is the panel cutout requirement for installation?

A: All three parts require a circular panel cutout of 4.95mm diameter with a 10-48 bushing thread. This specification is identical across the 34CMDP31B1M1RT, 200MDP3T1B1M1QEH, and T203SHZQE, ensuring direct mechanical interchangeability in existing panel designs.
