Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34DWMSP11B4M2RT is determined by the following critical parameters:

Circuit Configuration: SPDT topology is mandatory for functional equivalence in applications requiring single-pole, double-throw switching.

Mounting Type: Through-hole mounting is required for PCB assembly compatibility with the original design.

Termination Style: PC pin termination ensures mechanical and electrical compatibility with existing board layouts.

Ingress Protection: IP67 rating provides equivalent environmental sealing and protection against dust and water ingress.

Operating Temperature Range: -30°C to 85°C establishes the thermal operating envelope for component selection.

Actuator Configuration: Standard round actuator type with comparable length (10.16mm to 10.70mm) maintains mechanical interchangeability.

The substitute part 200AWMSP1T1A1M2QE from E-Switch meets these core substitution criteria while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (34DWMSP11B4M2RT): Select this Grayhill component for applications with voltage and current requirements not exceeding 20V AC/DC and 0.4VA. RoHS Compliance and Active product status ensure long-term availability and regulatory alignment.

Substitute Part (200AWMSP1T1A1M2QE): The E-Switch 200AWMSP1T1A1M2QE is suitable for applications requiring higher voltage (120V AC / 28V DC) and current (3A) capacity while maintaining identical circuit topology, mounting configuration, and environmental protection. ROHS3 Compliance and extended electrical life (50,000 cycles versus 30,000 cycles) provide enhanced performance margins. This substitute is appropriate when supply constraints affect the primary part or when application requirements exceed the original part's electrical ratings.

Both parts maintain Active product status and equivalent environmental sealing, supporting reliable long-term deployment.

Frequently Asked Questions (FAQ)

Q: Can the 200AWMSP1T1A1M2QE replace the 34DWMSP11B4M2RT in all applications?

A: The 200AWMSP1T1A1M2QE is a functional substitute only for applications where the circuit topology (SPDT On-On), mounting type (through-hole), and environmental protection (IP67) are required. The substitute part has higher voltage and current ratings, making it suitable for applications operating within or below the original part's specifications. Verify that your application does not depend on the specific electrical characteristics of the 34DWMSP11B4M2RT before substitution.

Q: What are the key differences between these two parts?

A: The primary differences are electrical ratings and electrical life. The 34DWMSP11B4M2RT is rated for 0.4VA at 20V with 30,000 electrical cycles. The 200AWMSP1T1A1M2QE is rated for 3A at 120V AC / 28V DC with 50,000 electrical cycles. Both share identical circuit configuration, mounting type, termination style, actuator type, ingress protection rating, and operating temperature range.

Q: Are the actuator lengths compatible?

A: The actuator lengths differ slightly: 10.70mm for the 34DWMSP11B4M2RT and 10.16mm for the 200AWMSP1T1A1M2QE. This 0.54mm difference is within typical mechanical tolerance for standard round actuators and does not affect functional interchangeability in through-hole applications.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS Compliant (34DWMSP11B4M2RT is RoHS Compliant; 200AWMSP1T1A1M2QE is ROHS3 Compliant). Both are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Which part should I select for new designs?

A: For new designs, select based on application voltage and current requirements. If your application requires 20V or less at 0.4VA or less, either part is suitable. If your application requires higher voltage or current capacity, the 200AWMSP1T1A1M2QE is the appropriate selection. Both parts are Active and support long-term availability.
