ET01MD1CSE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The ET01MD1CSE is an active-status toggle switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuit configuration with On-On switching function. This through-hole mounted component is rated for 3A at 120V AC and 28V DC, with IP57 ingress protection and epoxy sealed terminals. The part is in active production status with 745 units currently in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific application requirements necessitate alternative electrical or mechanical characteristics.

Substitute Part Grouping Explanation

Substitute parts for the ET01MD1CSE are identified based on matching core electrical and mechanical parameters that define functional equivalence in toggle switch applications. The primary substitution criteria are:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Through Hole)
• Actuator type and length (Standard Round, 6.10mm)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Actuator material (Brass, Chrome Plated)

Two substitute parts from E-Switch are identified. The first substitute (200AWMSP1T2A1M2QE) maintains electrical ratings of 3A at 120V AC and 28V DC, matching the primary part's power handling capability. The second substitute (200AWMSP1T2A1M2RE) operates at reduced electrical ratings of 0.4VA at 20V AC/DC, suitable for lower-power applications where the primary part's full rating is not required.

Parameter Comparison

Engineering Selection Recommendations

For Full-Rating Applications (3A @ 120V AC / 28V DC): The 200AWMSP1T2A1M2QE from E-Switch provides direct electrical equivalence to the ET01MD1CSE. Both parts maintain identical current and voltage ratings, ROHS3 compliance, and active product status. The E-Switch substitute offers improved ingress protection (IP67 versus IP57). Electrical life is reduced from 60,000 to 50,000 cycles; this difference is not significant for most industrial applications.

For Reduced-Power Applications (0.4VA @ 20V AC/DC): The 200AWMSP1T2A1M2RE is suitable only for applications where electrical requirements do not exceed 0.4VA at 20V. This part is not interchangeable with the ET01MD1CSE in circuits requiring the primary part's full 3A/120V rating. Both E-Switch substitutes maintain ROHS3 compliance and active production status.

Compliance Considerations: All three parts are ROHS3 compliant and carry active product status. The E-Switch parts are REACH Unaffected, while the C&K primary part is REACH Affected. Selection should account for supply chain and regulatory requirements specific to the application region.

Frequently Asked Questions (FAQ)

Q: Can 200AWMSP1T2A1M2QE directly replace ET01MD1CSE in all applications? A: Yes, for applications requiring 3A at 120V AC or 28V DC. The parts share identical electrical ratings, circuit configuration, mounting type, and actuator specifications. The E-Switch part provides superior ingress protection (IP67 vs. IP57) and maintains ROHS3 compliance.

Q: What is the difference between the two E-Switch substitutes? A: 200AWMSP1T2A1M2QE is rated for 3A at 120V AC/28V DC, matching the primary part's full electrical capacity. 200AWMSP1T2A1M2RE is rated for 0.4VA at 20V AC/DC and is suitable only for low-power applications. Both share identical mechanical specifications and ingress protection.

Q: Can 200AWMSP1T2A1M2RE replace ET01MD1CSE? A: Only in applications where circuit requirements do not exceed 0.4VA at 20V. The reduced electrical rating makes this part unsuitable for circuits designed for the primary part's 3A/120V capability.

Q: How do packaging differences affect substitution? A: ET01MD1CSE is supplied in Tray packaging, while both E-Switch substitutes are supplied in Bulk packaging. Packaging does not affect electrical or mechanical compatibility; it impacts only order quantity and handling logistics.

Q: Are there differences in electrical life between these parts? A: ET01MD1CSE is rated for 60,000 electrical cycles, while both E-Switch substitutes are rated for 50,000 cycles. For applications with high switching frequency, the primary part offers extended operational life.

Q: Do all parts meet the same environmental standards? A: All three parts operate across -30°C to 85°C and feature epoxy sealed terminals. E-Switch substitutes provide IP67 ingress protection compared to IP57 for the primary part, offering enhanced dust and water resistance.
