C&K 7201P1YZBES Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201P1YZBES is an active production toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features a flat anti-rotation actuator and satin chrome finish, designed for applications requiring reliable switching in compact form factors. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and circuit configuration align with the original specification, enabling component interchangeability in system designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7201P1YZBES is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Mounting type must be Panel Mount
• Panel cutout dimensions must be Circular - 6.35mm Dia
• Bushing thread must be 1/4-40
• Termination style must be Solder Lug
• Operating temperature range must encompass -30°C ~ 85°C

Electrical Compatibility Criteria:

• Current rating must equal or exceed 0.4VA
• Voltage rating (AC) must equal or exceed 20V
• Voltage rating (DC) must equal or exceed 20V

The E-Switch 100DP1T4B1M1QEH satisfies all mandatory mechanical and electrical compatibility criteria, with enhanced current rating (5A) and AC voltage rating (120V), while maintaining identical panel mount geometry and termination configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7201P1YZBES and E-Switch 100DP1T4B1M1QEH are active production components with ROHS3 compliance. The E-Switch 100DP1T4B1M1QEH provides superior electrical headroom with 5A current capacity and 120V AC rating, compared to the 0.4VA and 20V AC specifications of the C&K part. Both components maintain identical mechanical interfaces (panel cutout, bushing thread, termination) and operating temperature specifications, enabling direct substitution in panel-mount applications. Selection between these parts depends on circuit current and voltage requirements; the E-Switch variant accommodates higher-power switching applications while maintaining full mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T4B1M1QEH directly replace the C&K 7201P1YZBES in existing designs?

A: Yes. Both components share identical panel mount geometry (6.35mm circular cutout, 1/4-40 bushing thread), solder lug termination, and operating temperature range (-30°C ~ 85°C). The E-Switch part provides higher electrical ratings and is mechanically interchangeable.

Q: What are the key differences between these two DPDT toggle switches?

A: The primary differences are electrical ratings. The E-Switch 100DP1T4B1M1QEH is rated for 5A at 120V AC and 28V DC, while the C&K 7201P1YZBES is rated for 0.4VA at 20V AC/DC. The E-Switch part also features a standard round actuator versus the C&K flat anti-rotation actuator, and has lower electrical life (40,000 cycles versus 100,000 cycles).

Q: Are there packaging differences between these parts?

A: Yes. The C&K 7201P1YZBES is supplied in Tray packaging, while the E-Switch 100DP1T4B1M1QEH is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Which part should be selected for low-voltage, low-current applications?

A: The C&K 7201P1YZBES is optimized for applications operating at 20V or below with current requirements up to 0.4VA. The E-Switch 100DP1T4B1M1QEH accommodates higher voltage and current levels but is equally suitable for lower-power applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the C&K 7201P1YZBES and E-Switch 100DP1T4B1M1QEH are ROHS3 compliant.
