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

Part Overview

The C&K 7201SYZBES 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 satin chrome actuator with standard round geometry and solder lug termination. The 7201SYZBES is designed for applications requiring reliable switching in the low-voltage, low-current domain with an operating temperature range of -30°C to 85°C and 100,000 electrical cycle life. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical mounting compatibility, and circuit configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SYZBES are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Circuit configuration (DPDT required)
• Switch function (On-On required)
• Current rating (0.4VA AC/DC for direct substitution)
• Voltage rating (20V AC/DC for direct substitution)
• Mounting type (Panel Mount required)
• Panel cutout dimensions (Circular 6.35mm Dia required)
• Bushing thread (1/4-40 required)
• Termination style (Solder Lug required)
• Operating temperature range (-30°C ~ 85°C minimum)
• RoHS compliance status

The E-Switch 100 series parts listed below meet these criteria with variations in actuator geometry, electrical life, and packaging format.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (0.4VA, 20V AC/DC):

The E-Switch 100DP1T1B1M1REH and 100DP1T6B11M1REH are direct electrical equivalents to the 7201SYZBES, matching the 0.4VA current rating and 20V voltage specification. Both parts are ROHS3 compliant and active production items. The 100DP1T1B1M1REH features a standard round actuator with 10.41mm length, while the 100DP1T6B11M1REH provides a flat anti-rotation actuator at 12.30mm length. Selection between these two depends on actuator geometry requirements for the application. Both have reduced electrical life (40,000 cycles versus 100,000 cycles for the original part).

Higher-Rated Alternative (5A, 120V AC/DC):

The E-Switch 100DP1T6B11M1QEH provides elevated electrical ratings (5A at 120V AC, 28V DC) while maintaining identical mechanical mounting compatibility. This part is suitable for applications requiring higher current or voltage capacity within the same panel cutout and bushing thread specifications. The flat anti-rotation actuator and 12.30mm length match the 100DP1T6B11M1REH configuration.

All substitute parts maintain ROHS3 compliance, active product status, and compatibility with the 1/4-40 bushing thread and 6.35mm circular panel cutout of the original 7201SYZBES.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M1REH directly replace the C&K 7201SYZBES?

A: Yes, the 100DP1T1B1M1REH is a direct electrical equivalent with matching 0.4VA current rating and 20V voltage specification. Both parts feature DPDT On-On configuration, panel mount design with 1/4-40 bushing thread, and solder lug termination. The primary difference is reduced electrical life (40,000 cycles versus 100,000 cycles) and a slightly shorter actuator (10.41mm versus 10.67mm).

Q: What is the difference between the 100DP1T1B1M1REH and 100DP1T6B11M1REH?

A: Both parts share identical electrical ratings (0.4VA, 20V AC/DC) and mechanical mounting specifications. The primary differences are actuator type and length: the 100DP1T1B1M1REH has a standard round actuator at 10.41mm, while the 100DP1T6B11M1REH has a flat anti-rotation actuator at 12.30mm. Selection depends on panel space and actuator engagement requirements.

Q: When should the 100DP1T6B11M1QEH be used instead of the 0.4VA equivalents?

A: The 100DP1T6B11M1QEH is specified for applications requiring higher electrical capacity: 5A current rating and 120V AC (28V DC). This part maintains identical mechanical compatibility with the original 7201SYZBES panel cutout and bushing thread but is not a direct replacement for 0.4VA, 20V applications. Use this part only when the application circuit requires the elevated electrical ratings.

Q: Are all substitute parts RoHS compliant?

A: Yes, all listed substitute parts (100DP1T1B1M1REH, 100DP1T6B11M1REH, and 100DP1T6B11M1QEH) are ROHS3 compliant and meet the same environmental standards as the original 7201SYZBES.

Q: What packaging formats are available for the substitute parts?

A: The E-Switch 100 series substitute parts are supplied in bulk packaging, whereas the original C&K 7201SYZBES is available in tray packaging. Verify packaging requirements with your procurement process before finalizing part selection.

Q: Do the substitute parts have the same operating temperature range?

A: Yes, all substitute parts maintain the -30°C to 85°C operating temperature range specified for the original 7201SYZBES.
