C&K 7203P3CWCQE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7203P3CWCQE is an active production toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a flat anti-rotation actuator, PC pin termination, and IP67 ingress protection with epoxy sealed terminals. The part is ROHS3 compliant and maintains an operating temperature range of -30°C to 85°C with 40,000 electrical life cycles. Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters while meeting the same compliance and certification standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7203P3CWCQE is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular 6.35mm)
• Bushing thread specification (1/4-40)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C minimum)
• Electrical life rating (40,000 cycles minimum)
• RoHS compliance status (ROHS3)

Electrical Performance Considerations: Substitute parts must maintain electrical ratings sufficient for the application. The 7203P3CWCQE operates at 5A/120V AC and 28V DC. Substitute parts with lower current or voltage ratings are not interchangeable for equivalent applications.

The E-Switch 100DP3T1B1M2REH meets the mechanical and functional requirements but operates at reduced electrical ratings (0.4VA/20V), limiting its substitution to lower-power applications only.

Engineering Selection Recommendations

C&K 7203P3CWCQE (Primary Selection) This part is the specified component with active production status and full ROHS3 compliance. It is suitable for applications requiring 5A switching capacity at 120V AC or 28V DC with IP67 environmental protection. The part maintains REACH compliance and is available in production quantities.

E-Switch 100DP3T1B1M2REH (Limited Substitution) This part shares identical mechanical and functional characteristics but operates at significantly reduced electrical ratings (0.4VA/20V). Substitution is limited to applications where the lower current and voltage specifications are acceptable. The part is ROHS3 compliant and active in production. REACH status differs (Unaffected vs. Affected), which may impact supply chain considerations in regulated markets.

Selection between these parts must be based on the electrical requirements of the target application. The 7203P3CWCQE is required for full-rated 5A/120V AC applications. The 100DP3T1B1M2REH is suitable only for applications operating below 0.4VA and 20V maximum.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP3T1B1M2REH replace the C&K 7203P3CWCQE in all applications? A: No. The E-Switch part has lower electrical ratings (0.4VA/20V versus 5A/120V AC). Substitution is valid only for applications operating within the E-Switch electrical specifications. Direct replacement in full-rated applications will result in component failure or unsafe operation.

Q: What mechanical parameters ensure physical compatibility? A: Both parts share identical panel cutout dimensions (6.35mm circular), bushing thread specification (1/4-40), and PC pin termination. Physical installation compatibility is confirmed. Electrical compatibility must be verified separately based on application requirements.

Q: Are both parts compliant with current regulations? A: Both parts are ROHS3 compliant and active in production. The C&K 7203P3CWCQE is REACH Affected; the E-Switch 100DP3T1B1M2REH is REACH Unaffected. Regulatory requirements for the target market should be confirmed before final selection.

Q: What is the operating temperature range for both parts? A: Both parts operate across -30°C to 85°C. Temperature performance is equivalent between the two options.

Q: Do both parts provide the same environmental protection? A: The C&K 7203P3CWCQE provides IP67 ingress protection (dust tight, waterproof). The E-Switch 100DP3T1B1M2REH does not specify ingress protection rating. Environmental sealing requirements should be confirmed for the application.

Q: What is the electrical life expectancy? A: Both parts are rated for 40,000 electrical cycles, providing equivalent operational longevity under normal switching conditions.
