Toggle Switch SPDT 7101SYCRE Equivalent & Substitute Parts

Part Overview

The C&K 7101SYCRE is an active production toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with PC pin termination and epoxy sealed terminals for environmental protection. The part is currently in stock with 810 units available. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and functional specifications align within acceptable tolerances for direct replacement applications.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Current rating must be 5A (AC/DC)
• Voltage rating must be 120V AC minimum and 28V DC minimum

Mechanical Compatibility Requirements:

• 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 PC Pin
• Actuator type must be Standard Round

Environmental & Operational Requirements:

• Operating temperature range must encompass -30°C to 85°C
• Epoxy sealed terminals required
• Non-illuminated configuration

The E-Switch 100SP1T1B1M2QEH meets all critical electrical and mechanical parameters, confirming its status as a direct substitute for the 7101SYCRE in panel-mount toggle switch applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (7101SYCRE): The C&K 7101SYCRE is recommended for applications requiring maximum electrical life (100,000 cycles). This part is active in production and suitable for standard industrial panel-mount switching applications. Note that this part is RoHS non-compliant and REACH Affected, which may restrict use in certain regulated markets or applications with environmental compliance requirements.

Substitute Part (100SP1T1B1M2QEH): The E-Switch 100SP1T1B1M2QEH is recommended as a substitute when RoHS3 compliance and REACH Unaffected status are required. This part maintains full electrical and mechanical compatibility with the 7101SYCRE. The electrical life rating of 40,000 cycles is lower than the primary part; however, this remains suitable for general-purpose switching applications where the primary part's extended cycle life is not a design requirement. Higher inventory availability (4017 units) may support supply chain continuity.

Selection Criteria:

• Choose 7101SYCRE when maximum electrical life and established C&K supply chain are priorities
• Choose 100SP1T1B1M2QEH when RoHS3 compliance, REACH compliance, or E-Switch supply chain preference is required

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T1B1M2QEH be used as a direct replacement for the C&K 7101SYCRE?

A: Yes. Both parts share identical electrical ratings (5A, 120V AC, 28V DC, SPDT On-On), mechanical dimensions (6.35mm panel cutout, 1/4-40 bushing thread, PC pin termination), and operating temperature range (-30°C to 85°C). The 0.26mm difference in actuator length (10.67mm vs. 10.41mm) does not affect panel-mount compatibility.

Q: What is the difference in electrical life between these parts?

A: The 7101SYCRE is rated for 100,000 cycles, while the 100SP1T1B1M2QEH is rated for 40,000 cycles. Select the 7101SYCRE for applications requiring extended cycle life or frequent switching operations. The 100SP1T1B1M2QEH is suitable for standard industrial applications with moderate switching frequency.

Q: Are there compliance differences between these parts?

A: Yes. The 7101SYCRE is RoHS non-compliant and REACH Affected. The 100SP1T1B1M2QEH is RoHS3 Compliant and REACH Unaffected. Applications subject to RoHS or REACH regulations must use the E-Switch part.

Q: Do both parts use the same panel cutout and mounting hardware?

A: Yes. Both parts require a circular 6.35mm diameter panel cutout and use 1/4-40 bushing thread. No mechanical modifications to the panel or mounting assembly are required when substituting between these parts.

Q: What termination style do these parts use?

A: Both parts use PC pin termination, which is compatible with standard PCB-mount sockets and direct solder connections to printed circuit boards.

Q: Are both parts currently in production?

A: Yes. Both the 7101SYCRE and 100SP1T1B1M2QEH are active production parts with current inventory availability.
