E101SYCRE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The E101SYCRE is an active production toggle switch manufactured by C&K, configured as a single-pole double-throw (SPDT) panel mount switch with on-on functionality. This component is designed for applications requiring reliable switching at 7.5A AC/DC with 125V AC and 28V DC voltage ratings. Substitute parts are identified to provide equivalent electrical and mechanical performance for applications where the original part is unavailable or where alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E101SYCRE are qualified based on the following critical parameters that determine functional equivalence:

• Circuit configuration: SPDT (single-pole double-throw)
• Switch function: On-On
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Actuator type: Standard Round
• Operating temperature range: -30°C ~ 85°C
• Epoxy sealed terminals feature

Substitute parts must maintain compatibility with these mechanical and electrical interface parameters. Variations in current rating, voltage rating, actuator length, ingress protection rating, and electrical life cycle rating are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance. Selection between the E101SYCRE and substitute parts depends on application current requirements:

The E101SYCRE supports 7.5A AC/DC operation. Both substitute parts (100SP1T1B1M2QEH and 2M1-SP1-T1-B1-M2QE) are rated for 5A AC/DC operation. Applications requiring current levels between 5A and 7.5A must use the E101SYCRE.

For applications operating at 5A or below, both substitutes provide equivalent mechanical interface compatibility. The 2M1-SP1-T1-B1-M2QE offers enhanced ingress protection (IP67 versus IP57) and extended electrical life (50,000 cycles versus 40,000 cycles). The 100SP1T1B1M2QEH provides equivalent electrical life and ingress protection specifications are not documented.

All parts share identical panel cutout dimensions, bushing thread specifications, termination style, and operating temperature range, ensuring direct mechanical and electrical interface compatibility within the specified current and voltage parameters.

Frequently Asked Questions (FAQ)

Q: Can the 100SP1T1B1M2QEH or 2M1-SP1-T1-B1-M2QE be used in place of the E101SYCRE?

A: Direct substitution is possible only for applications operating at 5A or below. Both substitute parts are rated for 5A AC/DC maximum, while the E101SYCRE is rated for 7.5A AC/DC. If your application requires current levels above 5A, the E101SYCRE must be used.

Q: Are the panel mounting dimensions identical across all three parts?

A: Yes. All three parts share identical panel cutout dimensions (Circular - 6.35mm Dia) and bushing thread specifications (1/4-40), ensuring direct mechanical compatibility in panel mount applications.

Q: What is the difference in ingress protection between these parts?

A: The E101SYCRE provides IP57 protection (dust protected, waterproof). The 2M1-SP1-T1-B1-M2QE provides IP67 protection (dust tight, waterproof), offering enhanced sealing. The 100SP1T1B1M2QEH does not specify an ingress protection rating.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. All three parts are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the difference in electrical life between the E101SYCRE and the 2M1-SP1-T1-B1-M2QE?

A: The E101SYCRE is rated for 40,000 electrical cycles. The 2M1-SP1-T1-B1-M2QE is rated for 50,000 electrical cycles, providing extended operational life. The 100SP1T1B1M2QEH matches the E101SYCRE at 40,000 cycles.

Q: Are the actuator lengths compatible across all parts?

A: Actuator lengths are similar but not identical. The E101SYCRE has an actuator length of 10.16mm, while both substitutes measure approximately 10.40-10.41mm. These minor variations are within typical mechanical tolerances for panel mount toggle switches and do not affect functional compatibility.

Q: What voltage ratings apply to each part?

A: All three parts are rated for 28V DC operation. AC voltage ratings differ slightly: E101SYCRE and 2M1-SP1-T1-B1-M2QE are rated for 125V AC, while the 100SP1T1B1M2QEH is rated for 120V AC. Both 120V and 125V ratings are compatible with standard AC line voltage applications.
