Toggle Switch SPDT 7101SYCQE2 Equivalent & Substitute Parts

Part Overview

The C&K 7101SYCQE2 is an active production toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with PC pin termination and is designed for applications requiring reliable on-on switching functionality. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple vendors, and maintain design compatibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101SYCQE2 is determined by strict alignment of the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC minimum)
• Voltage ratings (120V AC, 28V DC minimum)
• Mounting type (Panel Mount)
• Actuator type (Standard Round)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C ~ 85°C)
• RoHS compliance status (ROHS3 Compliant)

The E-Switch 100SP1T1B1M2QEH meets all these critical parameters and qualifies as a direct substitute. Minor variations in actuator length (10.41mm vs. 10.67mm) and electrical life rating (40,000 vs. 100,000 cycles) do not affect functional interchangeability in standard panel-mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7101SYCQE2 and E-Switch 100SP1T1B1M2QEH are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for equivalent selection in panel-mount toggle switch applications. The C&K part offers extended electrical life (100,000 cycles), while the E-Switch alternative provides equivalent electrical and mechanical performance with epoxy sealed terminals. Selection between these parts should be based on supply availability, lead time requirements, and application-specific cycle life expectations.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T1B1M2QEH directly replace the C&K 7101SYCQE2 in existing designs?

A: Yes. Both parts share identical circuit configuration (SPDT), current rating (5A AC/DC), voltage ratings (120V AC / 28V DC), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and operating temperature range (-30°C ~ 85°C). PC pin termination and panel-mount configuration are identical.

Q: What is the significance of the actuator length difference (10.67mm vs. 10.41mm)?

A: The 0.26mm difference in actuator length does not affect panel-mount compatibility or functional operation. Both actuators are standard round type with identical engagement characteristics for on-on switching applications.

Q: How does the electrical life rating difference impact part selection?

A: The C&K part is rated for 100,000 cycles while the E-Switch part is rated for 40,000 cycles. Applications requiring extended cycle life should prioritize the C&K 7101SYCQE2. For standard industrial and commercial applications with moderate switching frequency, both parts are functionally equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both the C&K 7101SYCQE2 and E-Switch 100SP1T1B1M2QEH are ROHS3 compliant with unlimited moisture sensitivity (MSL 1).

Q: What is the difference between the actuator materials?

A: Both parts feature brass actuators with chrome plating, providing identical mechanical and corrosion resistance properties.
