Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (DPDT required)
• Switch function (On-On operation)
• Mounting type (Panel Mount)
• Termination style (PC Pin)
• Bushing thread specification (1/4-40)
• Actuator type and length compatibility with panel cutout

Electrical Compatibility Criteria:

• Current rating must equal or exceed 5A
• Voltage ratings must meet or exceed 120V AC and 28V DC requirements
• Operating temperature range must encompass -30°C to 85°C

Substitute Categories:

Direct Equivalent: C&K 7201MYCSE maintains identical electrical specifications, mechanical dimensions, and panel interface requirements. The primary distinction is active product status and RoHS compliance.

Similar Substitutes (Electroswitch A-Series): A223M1CWCQ, A223M1DCG, A223M1DCQ, and A223P31DCQ provide equivalent DPDT functionality with enhanced current ratings (6A) and voltage ratings (125V AC). These parts share identical mounting interfaces, termination style, and bushing specifications. A223P31DCQ features a flatted actuator with extended length (11.38mm), requiring verification of panel cutout compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: C&K 7201MYCSE is the primary equivalent, offering identical electrical and mechanical specifications with the advantage of active product status and RoHS compliance. This part maintains 100,000-cycle electrical life and operates within the original temperature range.

For Enhanced Specifications: Electroswitch A-Series parts (A223M1CWCQ, A223M1DCG, A223M1DCQ) provide higher current capacity (6A) and voltage ratings (125V AC) while maintaining mechanical compatibility. These parts are suitable for applications requiring increased electrical margin. All three variants share identical specifications except for packaging and ingress protection differences.

For Extended Actuator Length: A223P31DCQ features a flatted actuator with 11.38mm length, compared to the standard 5.08mm round actuator. This configuration requires panel cutout verification to ensure mechanical clearance and proper actuator engagement.

Compliance Considerations: All substitute parts carry RoHS compliance and active product status, addressing the obsolescence of the original 7201MYCME. Electroswitch parts show REACH status as either Vendor Undefined or Unaffected, requiring verification against specific regulatory requirements for your application.

Frequently Asked Questions (FAQ)

Q: Can A223M1CWCQ, A223M1DCG, and A223M1DCQ be used interchangeably?

A: Yes. These three Electroswitch parts share identical electrical specifications (6A, 125V AC, 28V DC), circuit configuration (DPDT), actuator type (standard round, 5.08mm), and mechanical interfaces (1/4-40 bushing, PC Pin termination). Selection between them depends on packaging requirements and ingress protection specifications.

Q: What is the key difference between A223M1DCQ and A223P31DCQ?

A: Both parts provide identical electrical performance and DPDT functionality. The primary difference is actuator geometry: A223M1DCQ features a standard round actuator at 5.08mm length, while A223P31DCQ has a flatted actuator at 11.38mm length. Panel cutout compatibility must be verified before selecting A223P31DCQ.

Q: Why do Electroswitch parts have lower electrical life (60,000 cycles vs. 100,000 cycles)?

A: The 7201MYCME and 7201MYCSE both specify 100,000-cycle electrical life, while Electroswitch A-Series parts specify 60,000 cycles. For applications requiring extended cycle life, the C&K 7201MYCSE is the appropriate selection.

Q: Are all substitute parts suitable for the same operating temperature range?

A: The 7201MYCME operates from -30°C to 85°C. All substitute parts operate from -30°C to 90°C, providing extended high-temperature capability. For applications limited to the original -30°C to 85°C range, all substitutes remain compatible.

Q: What does RoHS compliance mean for this application?

A: RoHS compliance indicates the part meets restrictions on hazardous substances. The original 7201MYCME is RoHS non-compliant, while all substitute parts are RoHS compliant. For new designs or systems with RoHS requirements, substitute parts are necessary.

Q: Can I use a 6A-rated switch in place of a 5A-rated switch?

A: Yes. The Electroswitch parts rated for 6A exceed the 5A requirement of the original part. Higher current ratings provide additional electrical margin and are suitable for direct substitution in applications designed for 5A operation.
