ET01MF1APE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The ET01MF1APE is a toggle switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) configuration with 0.4VA current rating at 20V. This through-hole, right-angle mounted switch is designed for On-On switching applications with an operating temperature range of -30°C to 85°C. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support and component sourcing.

Substitute Part Grouping Explanation

Substitution for the ET01MF1APE is determined by strict equivalence in the following critical parameters:

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

Substitute parts are grouped based on product status (Active vs. Obsolete) and compliance certifications. Variations in actuator length, ingress protection rating, electrical life cycles, and terminal sealing features are permitted within the substitution scope, as these do not affect core electrical compatibility or mechanical mounting.

Engineering Selection Recommendations

Primary Substitutes (Exact Voltage Match - 20V):

ET01MD1ABE (C&K) is the direct active equivalent, maintaining identical electrical specifications and voltage rating while offering ROHS3 compliance. This part is recommended as the first choice for direct replacement.

The Grayhill Inc. series (34CMSP12B2M6RT, 34CMSP12B4M6RT, 34CMSP13B2M6RT, 34DWMSP12B4M6RT) provides active alternatives with 20V voltage rating and ROHS3 compliance. Actuator length variations (5.33mm to 7.37mm) accommodate different panel mounting depths. The 34DWMSP12B4M6RT offers enhanced IP67 ingress protection compared to the original ET01MF1APE.

Carling Technologies 2SS-MSP1-T2-B4-M61RE meets all core electrical requirements with 20V rating and ROHS3 compliance. The shorter 4.65mm actuator length requires panel cutout verification before selection.

Secondary Substitutes (Higher Voltage Rating - 28V):

NKK Switches A12HH, A12JH, and A12JH-JA operate at 28V, exceeding the original 20V specification. These parts are electrically compatible in 20V applications due to voltage derating capability. A12JH-JA includes a black cap actuator feature. All three maintain ROHS3 compliance and the required operating temperature range.

Compliance Consideration:

All substitute parts carry ROHS3 compliance, meeting or exceeding the original RoHS Compliant status of the ET01MF1APE.

Frequently Asked Questions (FAQ)

Q: Can I use a 28V rated switch in a 20V application?

A: Yes. The NKK Switches A12HH, A12JH, and A12JH-JA are rated for 28V but operate safely at 20V. Higher voltage ratings provide design margin in lower-voltage applications.

Q: What is the significance of actuator length differences?

A: Actuator length affects panel mounting depth and user interface feel. The ET01MF1APE uses 6.10mm. Substitutes range from 4.65mm to 7.37mm. Verify panel cutout dimensions and desired actuator protrusion before selection.

Q: Does ingress protection rating affect substitution?

A: Ingress protection is an enhancement, not a requirement for substitution. The original ET01MF1APE specifies IP57. Substitutes with IP67 (34DWMSP12B4M6RT, 2SS-MSP1-T2-B4-M61RE) provide superior environmental sealing without affecting electrical compatibility.

Q: Are there differences in electrical life cycles?

A: Yes. The ET01MF1APE is rated for 60,000 cycles. Most Grayhill and Carling substitutes are rated for 30,000 cycles, while NKK Switches offer 50,000 cycles. Select based on application duty cycle requirements.

Q: What packaging options are available?

A: ET01MD1ABE is supplied in Bulk packaging. Grayhill and Carling parts are supplied in Bulk. NKK Switches (A12HH, A12JH, A12JH-JA) are supplied in Tray packaging. Verify packaging requirements for assembly processes.

Q: Is the ET01MF1APE still available?

A: The ET01MF1APE is obsolete. Active substitutes must be selected from the provided list. ET01MD1ABE (same manufacturer, C&K) is the recommended replacement for new designs and ongoing production.
