Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 34DWMSP16B4M2RT are grouped based on electrical and mechanical compatibility within SPDT toggle switch applications. The substitution logic is determined by the following key parameters:

Group 1: Direct Electrical Equivalents (0.4VA / 20V Rating)

• ET01LD1CBE (C&K)

This substitute maintains identical voltage and current ratings (0.4VA, 20V AC/DC), SPDT circuit configuration, and On-On switch function. Both parts support the same operating temperature range (-30°C to 85°C) and feature epoxy sealed terminals with PC pin termination. The primary differences are actuator length (8.13mm vs. 6.70mm) and ingress protection rating (IP57 vs. IP67).

Group 2: Higher-Rated Substitutes (3A / 120V Rating)

• 200AWMSP1T2A1M2QE (E-Switch)
• ET01MD1CGE (C&K)

These substitutes provide elevated electrical ratings (3A at 120V AC, 28V DC) while maintaining SPDT configuration and On-On function. Both support the same operating temperature range and feature epoxy sealed terminals with PC pin termination. These parts are suitable for applications requiring higher switching capacity than the base 34DWMSP16B4M2RT specification.

All substitute parts share the following core characteristics with the main part:

• SPDT circuit topology
• On-On switch function
• Through-hole mounting
• PC pin termination
• Standard round actuator
• Non-illuminated operation
• Brass chrome-plated actuator material
• Epoxy sealed terminals
• Operating temperature -30°C to 85°C
• Unthreaded bushing
• Active product status

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Specifications):

ET01LD1CBE from C&K provides electrical equivalence to the 34DWMSP16B4M2RT with matching 0.4VA and 20V ratings. This part maintains SPDT configuration, On-On function, and operating temperature range. The ET01LD1CBE carries ROHS3 compliance and is REACH Affected. The primary design consideration is the increased actuator length (8.13mm vs. 6.70mm) and reduced ingress protection rating (IP57 vs. IP67). This substitute is suitable when panel cutout dimensions accommodate the longer actuator and IP57 protection meets application requirements.

For Enhanced Electrical Capacity:

200AWMSP1T2A1M2QE (E-Switch) and ET01MD1CGE (C&K) both provide 3A at 120V AC ratings with 28V DC capability. Both maintain SPDT configuration and On-On function across the same operating temperature range. The E-Switch part (200AWMSP1T2A1M2QE) offers IP67 ingress protection matching the original specification, while the C&K part (ET01MD1CGE) provides IP57 protection. Both carry ROHS3 compliance. The E-Switch part is REACH Unaffected, while the C&K part is REACH Affected. These substitutes support applications requiring higher switching capacity than the base 0.4VA specification.

Compliance Considerations:

All substitute parts maintain Moisture Sensitivity Level 1 (Unlimited) and support the -30°C to 85°C operating temperature range. The 34DWMSP16B4M2RT is RoHS Compliant, while all substitutes are ROHS3 Compliant. REACH status differs: the Grayhill and E-Switch parts are REACH Unaffected, while both C&K parts are REACH Affected. Design teams must verify REACH compliance requirements for their specific application and regulatory jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can ET01LD1CBE be used as a direct replacement for 34DWMSP16B4M2RT?

A: ET01LD1CBE provides electrical equivalence with identical 0.4VA and 20V ratings, SPDT configuration, and On-On function. However, the actuator length differs (8.13mm vs. 6.70mm), and ingress protection is IP57 rather than IP67. Verify that panel cutout dimensions accommodate the longer actuator and that IP57 protection meets application environmental requirements.

Q: What is the difference between the two higher-rated substitutes (200AWMSP1T2A1M2QE and ET01MD1CGE)?

A: Both parts provide 3A at 120V AC and 28V DC ratings with SPDT configuration and On-On function. The primary differences are: 200AWMSP1T2A1M2QE (E-Switch) offers IP67 ingress protection and is REACH Unaffected; ET01MD1CGE (C&K) provides IP57 ingress protection and is REACH Affected. Actuator length is 6.10mm for both. Select based on ingress protection requirements and REACH compliance needs.

Q: Are all substitute parts suitable for the same environmental conditions as the original 34DWMSP16B4M2RT?

A: All substitute parts support the same operating temperature range (-30°C to 85°C) and feature epoxy sealed terminals. However, ingress protection ratings differ: the original part and 200AWMSP1T2A1M2QE provide IP67 (Dust Tight, Waterproof), while ET01LD1CBE and ET01MD1CGE provide IP57 (Dust Protected, Waterproof). Verify that the reduced ingress protection rating of IP57 alternatives meets application environmental specifications.

Q: What are the electrical life differences among these parts?

A: The 34DWMSP16B4M2RT is rated for 30,000 electrical cycles. The E-Switch 200AWMSP1T2A1M2QE provides 50,000 cycles, and both C&K parts (ET01LD1CBE and ET01MD1CGE) provide 60,000 cycles. Higher cycle ratings provide extended operational life for applications with frequent switching.

Q: Do all parts use the same termination and mounting style?

A: Yes. All parts feature PC pin termination and through-hole mounting with unthreaded bushings. Panel cutout dimensions are consistent across all parts. The primary mechanical difference is actuator length: 6.70mm (original), 6.10mm (200AWMSP1T2A1M2QE and ET01MD1CGE), and 8.13mm (ET01LD1CBE).

Q: What compliance certifications should I verify for my application?

A: All parts are RoHS or ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). REACH status varies: 34DWMSP16B4M2RT and 200AWMSP1T2A1M2QE are REACH Unaffected; ET01LD1CBE and ET01MD1CGE are REACH Affected. Verify REACH compliance requirements based on your application's regulatory jurisdiction and end-use market.

Q: Can I use a higher-rated substitute (3A / 120V) in place of the 0.4VA / 20V original part?

A: Yes. Higher-rated substitutes (200AWMSP1T2A1M2QE and ET01MD1CGE) are electrically compatible with applications designed for the lower 0.4VA / 20V specification. The higher ratings provide additional capacity margin. Verify that actuator length and ingress protection rating meet your mechanical and environmental requirements.
