Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Circuit Configuration: DPDT
• Switch Function: On-On
• Mounting Type: Panel Mount
• Panel Cutout Dimensions: Circular - 6.35mm Dia
• Bushing Thread: 1/4-40
• Termination Style: PC Pin
• Operating Temperature Range: -30°C ~ 85°C

Electrical Compatibility Parameters:

• Current Rating: 0.4VA (AC/DC)
• Voltage Rating - AC: 20 V
• Voltage Rating - DC: 20 V

All identified substitute parts meet these mandatory and electrical compatibility requirements. Variations in actuator type, actuator length, electrical life cycles, and manufacturer-specific features do not affect functional substitution within the specified electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with ROHS3 compliance, ensuring regulatory alignment with the original C&K 7201L40YCBE. Selection among substitutes should be based on the following criteria:

Direct Electrical Equivalents (0.4VA, 20V AC/DC):

• E-Switch 100AWDP1T1B1M2REH: Offers IP67 ingress protection rating, suitable for applications requiring enhanced environmental sealing. Electrical life rated at 30,000 cycles.
• E-Switch 100DP1T6B15M2RE: Features flat anti-rotation actuator design with 12.30mm actuator length. Electrical life rated at 40,000 cycles.
• TE Connectivity 2-1825138-4: Gemini A series with standard round actuator. Electrical life rated at 6,000 cycles. REACH Affected status applies.

Higher Electrical Rating Alternative:

• E-Switch 100DP1T1B1M2QEH: Rated for 5A AC/DC and 120V AC / 28V DC. This part exceeds the electrical requirements of the original specification and is suitable for applications requiring higher current or voltage capacity within the same mechanical footprint.

All substitute parts maintain identical mechanical compatibility through matching panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and termination style (PC Pin).

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100DP1T1B1M2QEH be used as a direct substitute for the C&K 7201L40YCBE?

A: E-Switch 100DP1T1B1M2QEH is mechanically and functionally compatible. However, it is rated for 5A AC/DC and 120V AC / 28V DC, which exceeds the original specification of 0.4VA at 20V. This part is suitable for applications where higher electrical capacity is acceptable or beneficial.

Q: What is the significance of the IP67 rating on E-Switch 100AWDP1T1B1M2REH?

A: IP67 designation indicates dust-tight and waterproof performance. This rating is relevant only if the application environment requires enhanced protection against moisture or particulate ingress. For standard panel-mount applications without such environmental demands, this feature does not affect substitution eligibility.

Q: How do actuator type differences affect substitution?

A: Actuator type (lever for cap, standard round, or flat anti-rotation) affects user interface and mechanical engagement but does not impact electrical switching performance. Selection should be based on panel design requirements and user interaction preferences.

Q: Are there compliance differences between substitute parts?

A: All listed substitutes are ROHS3 compliant. TE Connectivity 2-1825138-4 carries REACH Affected status, while E-Switch parts are REACH Unaffected. The original C&K 7201L40YCBE is REACH Affected. Compliance requirements should be verified against specific application and regional regulations.

Q: What is the impact of electrical life cycle ratings?

A: Electrical life ratings (ranging from 6,000 to 100,000 cycles) indicate the expected operational lifespan under specified switching conditions. The original C&K part is rated for 100,000 cycles. Substitute parts with lower ratings are suitable for applications with lower switching frequency requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, all substitute parts maintain identical mechanical mounting specifications (panel cutout, bushing thread, termination style) and operate within the same electrical envelope. Direct board-level substitution is supported without design modification.
