C&K 7101SPYCME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SPYCME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features an anti-rotation actuator, epoxy sealed terminals, and PC pin termination. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this specific model is no longer available from the manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 7101SPYCME is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid substitution relationships:

Primary Substitution Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Panel Mount
• Termination style: PC Pin
• Bushing thread: 1/4-40
• Current rating: Minimum 5A (AC/DC)
• Voltage rating: Minimum 120V AC and 28V DC
• Actuator material: Brass, Chrome Plated
• Features: Epoxy Sealed Terminals

Direct Equivalent: The C&K 7101SPYCSE represents a direct equivalent within the same manufacturer's 7000 series. This part maintains identical electrical specifications, mechanical dimensions, and termination characteristics while offering active product status.

Similar Substitutes: The Electroswitch A123S1 series parts (A123S1YCQ, A123S1DCQ, A123S1CWCG) provide functional substitution with enhanced electrical ratings (6A at 125V AC) and extended operating temperature range (-30°C to 90°C). These parts maintain the required SPDT circuit, On-On function, panel mount configuration, PC pin termination, and 1/4-40 bushing thread. Differences in actuator type (Standard Round vs. Anti-Rotation) and panel cutout dimensions do not preclude substitution when mechanical envelope permits.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical and Mechanical Specifications): Select C&K 7101SPYCSE. This part maintains identical electrical ratings, mechanical envelope, and termination characteristics as the obsolete 7101SPYCME while offering active product status and continued manufacturer support. Both parts are RoHS compliant and suitable for applications requiring 5A at 120V AC operation.

For Enhanced Performance Applications: The Electroswitch A123S1 series (A123S1YCQ, A123S1DCQ, A123S1CWCG) provides higher current capacity (6A) and voltage rating (125V AC), making these parts suitable for applications with margin requirements or future design upgrades. These parts maintain all critical mechanical and electrical compatibility parameters while offering extended operating temperature range. All three Electroswitch variants are RoHS compliant and actively manufactured.

Compliance Considerations: All substitute parts maintain RoHS compliance. The C&K 7101SPYCSE carries RoHS Compliant status with REACH Affected designation. The Electroswitch A123S1 series parts carry RoHS Compliant status with Vendor Undefined REACH status. Selection should account for specific regulatory requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can the Electroswitch A123S1 series parts directly replace the C&K 7101SPYCME? A: Yes, with mechanical envelope verification. The A123S1 series maintains the required SPDT circuit, On-On function, panel mount configuration, PC pin termination, and 1/4-40 bushing thread. The primary difference is actuator type (Standard Round vs. Anti-Rotation) and panel cutout dimensions. Verify that the panel cutout and actuator geometry are compatible with your application before substitution.

Q: What is the difference between the C&K 7101SPYCSE and the Electroswitch A123S1 series? A: The C&K 7101SPYCSE is a direct equivalent offering identical electrical ratings (5A at 120V AC) and mechanical specifications. The Electroswitch A123S1 series provides higher electrical ratings (6A at 125V AC) and extended temperature range (-30°C to 90°C vs. -30°C to 85°C). The A123S1 series has lower electrical life (60,000 cycles vs. 100,000 cycles). Choose based on application requirements for current capacity and cycle life.

Q: Are all substitute parts panel-mount compatible with the original 7101SPYCME? A: All substitute parts are panel-mount switches with 1/4-40 bushing thread. However, the C&K 7101SPYCME specifies a circular 6.35mm diameter panel cutout, while the Electroswitch A123S1 series does not specify panel cutout dimensions. Verify mechanical compatibility with your specific panel before substitution.

Q: What is the impact of different actuator types on substitution? A: The 7101SPYCME features an anti-rotation actuator, while the Electroswitch A123S1 series uses a standard round actuator. Both provide On-On switch function and are mechanically compatible with 1/4-40 bushing installation. The actuator type difference does not affect electrical performance or PC pin termination compatibility.

Q: Are there inventory considerations for these substitute parts? A: The C&K 7101SPYCSE offers 944 pieces in stock. The Electroswitch A123S1 series offers 951 pieces (A123S1YCQ), 914 pieces (A123S1DCQ), and 697 pieces (A123S1CWCG) in stock. All parts are available as new original components.
