ET01MF1V3BE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The ET01MF1V3BE is a toggle switch manufactured by C&K, classified as SPDT (Single Pole Double Throw) with On-On switching function. This through-hole mounted component is rated for 0.4VA at 20V AC/DC and features an ESD conductive bushing with IP57 ingress protection. The product is currently obsolete, making identification of functionally equivalent alternatives essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ET01MF1V3BE is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C

Secondary Compatibility Factors:

• Actuator type: Standard Round
• Actuator length tolerance
• Bushing thread type: Unthreaded

Parts meeting all primary criteria are classified as direct electrical and mechanical substitutes. Variations in actuator length, ingress protection rating, or electrical life do not disqualify substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Electrical and Mechanical Equivalence):

The following parts satisfy all primary substitution criteria and are classified as direct replacements:

• 200MSP1T2B2VS2RE (E-Switch): Active product status with ROHS3 compliance. Actuator length 5.33mm represents minor dimensional variance. Suitable for immediate procurement.

• 200MSP1T2B4VS2RE (E-Switch): Active product status with ROHS3 compliance. Identical electrical specifications to 200MSP1T2B2VS2RE. Suitable for immediate procurement.

• 200MSP1T5B2VS2RE (E-Switch): Active product status with ROHS3 compliance. Actuator length 7.88mm accommodates applications requiring extended actuation reach. Suitable for immediate procurement.

• 34DWMSP12B4V2RT (Grayhill Inc.): Active product status with ROHS3 compliance. Actuator length 6.10mm matches original specification. IP67 ingress protection exceeds original IP57 rating. Suitable for immediate procurement.

• ET01MD1CBE (C&K): Active product status with ROHS3 compliance. Same manufacturer as original part. Actuator length 6.10mm matches original specification. Recommended for design continuity. Note: REACH Status listed as Affected; verify compliance requirements for specific applications.

Conditional Substitute (Voltage Rating Variance):

• A12JB (NKK Switches): Active product status with ROHS3 compliance. Voltage rating 28V AC/DC exceeds original 20V specification, providing operational margin. Suitable for applications where higher voltage tolerance is acceptable. Actuator length 6.30mm represents minor dimensional variance.

Frequently Asked Questions (FAQ)

Q: Can I use 200MSP1T5B2VS2RE as a direct replacement for ET01MF1V3BE?

A: Yes. Both parts share identical electrical specifications (0.4VA, 20V AC/DC, SPDT, On-On function) and mounting configuration (through-hole, PC pin termination). The actuator length difference (7.88mm vs. 6.10mm) requires verification against panel cutout and mechanical clearance requirements in your application.

Q: What is the difference between the E-Switch 200MSP1 series variants?

A: The 200MSP1T2B2VS2RE, 200MSP1T2B4VS2RE, and 200MSP1T5B2VS2RE differ only in actuator length (5.33mm, 5.33mm, and 7.88mm respectively). All three share identical electrical ratings and are functionally equivalent for circuit applications.

Q: Why is A12JB listed as a substitute if the voltage rating is different?

A: The A12JB operates at 28V AC/DC, which exceeds the original 20V specification. This higher voltage rating does not prevent substitution in circuits designed for 20V operation, as the component will operate within its safe operating region. However, applications with strict voltage matching requirements should select alternatives with 20V ratings.

Q: Is ET01MD1CBE preferred over E-Switch alternatives?

A: ET01MD1CBE is manufactured by C&K, the same company as the original ET01MF1V3BE, providing design continuity and potential supply chain advantages. However, all listed substitutes meet electrical and mechanical requirements. Selection should be based on availability, lead time, and compliance verification for your specific application.

Q: What does ROHS3 compliance mean compared to RoHS Compliant?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. The original part's RoHS Compliant status and all substitute parts' ROHS3 status confirm hazardous substance restrictions are met.

Q: Can I use these substitutes in high-humidity or corrosive environments?

A: The original ET01MF1V3BE features IP57 ingress protection. Substitute 34DWMSP12B4V2RT provides IP67 protection, offering enhanced environmental sealing. E-Switch 200MSP1 series parts do not specify ingress protection ratings. For applications requiring environmental protection, verify ingress protection specifications against environmental exposure requirements.
