Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7201SCWCBE is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria (Must Match):

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular 6.35mm diameter
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C

Secondary Compatibility Factors:

• Actuator type and length (minor mechanical variations acceptable within panel mount constraints)
• Electrical life rating (lower ratings indicate reduced cycle durability)
• Ingress protection rating (IP67 preferred but not mandatory for all applications)
• Actuator material composition (brass plating variations)

Substitute parts are grouped based on full alignment with primary criteria. Variations in secondary factors are noted to support application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

Full Electrical and Mechanical Equivalents:

E-Switch 100AWDP1T1B1M2REH and TE Connectivity 2-1825138-4 meet all primary substitution criteria for the C&K 7201SCWCBE. Both parts maintain identical voltage and current ratings, circuit configuration, and mechanical mounting specifications. The E-Switch 100AWDP1T1B1M2REH provides IP67 ingress protection matching the original specification. The TE Connectivity 2-1825138-4 omits IP67 rating but maintains all electrical parameters. Both are ROHS3 compliant and active in production.

Partial Electrical Equivalents with Derating Considerations:

E-Switch 100DP1T1B1M2QEH operates at higher voltage and current ratings (5A at 120V AC, 28V DC) compared to the 0.4VA 20V specification of the C&K 7201SCWCBE. This part is electrically suitable for applications requiring higher power handling but introduces over-specification for low-power circuits. Mechanical compatibility is maintained. This part lacks IP67 ingress protection.

E-Switch 100DP1T6B15M2RE matches electrical specifications (0.4VA at 20V) but features a flat anti-rotation actuator and longer actuator length (12.30mm versus 10.67mm). Mechanical compatibility depends on panel cutout clearance and actuator engagement requirements. This part lacks IP67 ingress protection.

Compliance and Production Status:

All substitute parts are ROHS3 compliant and maintain active production status. The C&K 7201SCWCBE carries REACH Affected status, while E-Switch substitutes are REACH Unaffected. TE Connectivity 2-1825138-4 is REACH Affected, matching the original part's regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100DP1T1B1M2QEH replace the C&K 7201SCWCBE in all applications?

A: E-Switch 100DP1T1B1M2QEH maintains identical mechanical mounting and circuit configuration but operates at higher electrical ratings (5A at 120V AC versus 0.4VA at 20V). This part is electrically compatible for the specified 0.4VA 20V application but represents over-specification. The part lacks IP67 ingress protection. Substitution is valid for applications not requiring IP67 sealing.

Q: What is the impact of different electrical life ratings among substitute parts?

A: The C&K 7201SCWCBE is rated for 100,000 electrical cycles. E-Switch 100AWDP1T1B1M2REH provides 30,000 cycles, E-Switch 100DP1T1B1M2QEH and 100DP1T6B15M2RE provide 40,000 cycles, and TE Connectivity 2-1825138-4 provides 6,000 cycles. Lower cycle ratings indicate reduced durability in high-frequency switching applications. Selection should account for actual application duty cycle requirements.

Q: Are there mechanical compatibility concerns with the E-Switch 100DP1T6B15M2RE flat anti-rotation actuator?

A: The E-Switch 100DP1T6B15M2RE features a flat anti-rotation actuator design with 12.30mm length compared to the standard round 10.67mm actuator of the C&K 7201SCWCBE. Both parts maintain identical panel cutout dimensions (6.35mm circular) and bushing thread (1/4-40). Mechanical compatibility depends on panel thickness, actuator engagement depth, and operator interface requirements. Physical validation is necessary for applications with tight mechanical constraints.

Q: Which substitute part best matches the C&K 7201SCWCBE specification?

A: E-Switch 100AWDP1T1B1M2REH provides the closest match, maintaining all primary electrical specifications, IP67 ingress protection, and standard round actuator configuration. TE Connectivity 2-1825138-4 also meets all electrical criteria but omits IP67 protection. Both are suitable direct replacements for applications requiring full specification compliance.

Q: What is the significance of REACH compliance status differences?

A: The C&K 7201SCWCBE and TE Connectivity 2-1825138-4 are REACH Affected, indicating regulatory substance restrictions apply. E-Switch substitutes are REACH Unaffected. For applications subject to REACH compliance requirements, the TE Connectivity part maintains regulatory alignment with the original specification. E-Switch parts may require compliance verification for regulated applications.

Q: Can the higher voltage-rated E-Switch 100DP1T1B1M2QEH be used in a 20V circuit?

A: Yes. The E-Switch 100DP1T1B1M2QEH is rated for 120V AC and 28V DC, which exceeds the 20V requirement. Operating this part at 20V is within its electrical specification and presents no functional risk. However, this part lacks IP67 ingress protection and represents electrical over-specification for the application.
