C&K 7201SYCLE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SYCLE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) 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 designs. The 7201SYCLE features a standard round actuator with epoxy-sealed PC pin termination and operates across -30°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Circuit configuration (DPDT required)
• Switch function (On-On operation)
• Current rating (minimum 5A AC/DC)
• Voltage ratings (minimum 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator type and length (Standard Round, 10.67mm nominal)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular 6.35mm Dia)
• Bushing thread (1/4-40)
• Operating temperature range (minimum -30°C to 85°C)

Substitute parts are grouped into two categories: direct equivalents from C&K with improved compliance status, and functionally compatible alternatives from other manufacturers that meet or exceed the electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - C&K 7201SYCRE

The C&K 7201SYCRE is the primary substitute for the obsolete 7201SYCLE. Both parts share identical electrical ratings (5A at 120V AC/28V DC), mechanical dimensions, and actuator specifications. The 7201SYCRE maintains the same 100,000-cycle electrical life and operating temperature range. The key advantage is active product status and RoHS compliance, making it suitable for new designs and systems requiring regulatory compliance. REACH status differs (REACH Affected vs. REACH Unaffected), which may impact supply chain considerations depending on application region.

Alternative Substitutes - Grayhill and Electroswitch Options

The Grayhill 34ADP11B1M2QT and Electroswitch A223S1 series (A223S1DCQ, A223S1YCG, A223S1YCQ) provide functional alternatives with enhanced current ratings (6A vs. 5A) and higher AC voltage ratings (125V vs. 120V). These parts maintain mechanical compatibility through identical panel cutout dimensions, bushing threads, and PC pin termination. Operating temperature ranges extend to 90°C, exceeding the original specification. All substitute options are RoHS compliant and carry active product status.

Electrical life varies among alternatives: the Grayhill part provides 40,000 cycles, while Electroswitch options deliver 60,000 cycles, both lower than the original 100,000-cycle rating. This difference should be evaluated against application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7201SYCRE directly replace the 7201SYCLE without circuit modification?

A: Yes. The 7201SYCRE is a direct equivalent with identical electrical ratings, mechanical dimensions, and termination style. No circuit or panel modifications are required.

Q: What are the key differences between the C&K 7201SYCRE and Electroswitch A223S1 series?

A: The primary differences are current rating (5A vs. 6A), electrical life (100,000 vs. 60,000 cycles), and compliance status. The Electroswitch parts offer higher current capacity and extended temperature range (-30°C to 90°C). Panel cutout dimensions are not specified for Electroswitch parts, requiring verification before mechanical integration.

Q: Is the Grayhill 34ADP11B1M2QT suitable for applications requiring 100,000-cycle life?

A: No. The Grayhill part is rated for 40,000 electrical cycles, significantly lower than the original 100,000-cycle specification. Applications with high switching frequency should use the C&K 7201SYCRE or Electroswitch alternatives.

Q: Do all substitute parts meet RoHS requirements?

A: Yes. All listed substitutes (7201SYCRE, 34ADP11B1M2QT, A223S1DCQ, A223S1YCG, A223S1YCQ) are RoHS compliant. The original 7201SYCLE is RoHS non-compliant.

Q: Are there packaging differences between substitute options?

A: The C&K 7201SYCRE packaging is not specified in available data. Grayhill and Electroswitch parts are supplied in bulk packaging. Confirm packaging requirements with supplier specifications before procurement.

Q: Can Electroswitch A223S1 parts be used interchangeably within the series?

A: The A223S1DCQ, A223S1YCG, and A223S1YCQ variants share identical electrical and mechanical specifications. Differences are limited to internal actuator or terminal configurations not affecting external compatibility. Verify specific variant requirements for your application.
