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

Part Overview

The C&K 7101SYCME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features epoxy-sealed terminals, brass chrome-plated actuator, and 100,000 electrical cycle rating, suitable for industrial control and panel-mounted switching applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Direct Electrical Compatibility Requirements:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: minimum 5A (AC/DC)
• Voltage rating: minimum 120V AC, 28V DC
• Termination style: PC Pin

Mechanical Compatibility Requirements:

• Mounting type: Panel Mount
• Bushing thread: 1/4-40
• Panel cutout dimensions: Circular 6.35mm Dia (where specified)
• Actuator type: Standard Round

Compliance Requirements:

• RoHS compliance status
• REACH status alignment

Substitute parts are grouped into two categories: direct manufacturer equivalents from C&K and functionally similar alternatives from other manufacturers that meet or exceed the electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: C&K 7101SYCSE

The 7101SYCSE is the direct manufacturer equivalent from C&K. It maintains identical electrical ratings (5A, 120V AC, 28V DC), mechanical specifications (panel mount, 1/4-40 bushing, PC pin termination), and operating temperature range (-30°C to 85°C). Both parts share the same 100,000 electrical cycle rating and epoxy-sealed terminal features. The 7101SYCSE is currently in active production status with 712 units in stock, providing immediate availability. RoHS compliance is maintained. This part is the recommended first choice for direct replacement in existing designs.

Secondary Substitutes: Electroswitch A123S1 Series (A123S1CWCG, A123S1DCQ, A123S1YCQ)

The Electroswitch A123 series parts provide functional equivalence with enhanced electrical ratings. All three variants deliver 6A current capacity (exceeding the 5A requirement) and 125V AC rating (exceeding the 120V requirement). Mechanical compatibility is confirmed through identical bushing thread (1/4-40), PC pin termination, and panel-mount configuration. Operating temperature extends to 90°C (compared to 85°C). These parts are RoHS compliant and currently in active production. The trade-off is reduced electrical life (60,000 cycles versus 100,000 cycles). Selection among the three Electroswitch variants should be based on specific ingress protection requirements: A123S1CWCG includes splash-proof protection, while A123S1DCQ and A123S1YCQ do not specify ingress protection.

Frequently Asked Questions (FAQ)

Q: Can the 7101SYCSE directly replace the obsolete 7101SYCME without circuit modification?

A: Yes. The 7101SYCSE maintains identical electrical specifications (5A, 120V AC, 28V DC), circuit configuration (SPDT On-On), and mechanical mounting parameters (panel mount, 1/4-40 bushing, PC pin termination). No circuit redesign is required.

Q: What are the key differences between the C&K 7101SYCSE and Electroswitch A123S1 series substitutes?

A: The primary differences are current and voltage ratings, and electrical life. The C&K 7101SYCSE matches the original 5A/120V AC specification and 100,000 cycle rating. The Electroswitch A123S1 series provides higher ratings (6A/125V AC) but reduced electrical life (60,000 cycles). Both maintain identical mechanical compatibility and PC pin termination.

Q: Are the Electroswitch A123S1 parts suitable for applications requiring 100,000 electrical cycles?

A: The Electroswitch A123S1 series is rated for 60,000 electrical cycles, which is lower than the original 7101SYCME specification of 100,000 cycles. Application suitability depends on actual cycle requirements. For applications requiring 100,000+ cycles, the C&K 7101SYCSE is the appropriate choice.

Q: Do all substitute parts maintain the same panel cutout dimensions?

A: The C&K 7101SYCSE specifies identical panel cutout dimensions (Circular 6.35mm Dia). The Electroswitch A123S1 series does not specify panel cutout dimensions in the provided data. Mechanical verification is required before panel integration.

Q: What is the difference between A123S1CWCG, A123S1DCQ, and A123S1YCQ?

A: All three parts share identical electrical ratings (6A, 125V AC, 28V DC), mechanical specifications, and operating temperature range (-30°C to 90°C). The A123S1CWCG includes splash-proof ingress protection; the A123S1DCQ and A123S1YCQ do not specify ingress protection. Selection should be based on environmental exposure requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The C&K 7101SYCSE is RoHS compliant. All Electroswitch A123S1 variants (A123S1CWCG, A123S1DCQ, A123S1YCQ) are RoHS compliant.
