Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201TCWCKES2 is determined by the following critical parameters:

Mechanical Compatibility:

• Panel mount configuration with circular 11.91mm diameter cutout
• Bushing thread specification 15/32-32
• Standard round actuator with 17.45mm length
• PC pin termination style

Electrical Compatibility:

• DPDT circuit configuration with On-On switching function
• Voltage rating minimum of 20V AC and 20V DC
• Current rating minimum of 0.4VA AC/DC

Environmental Requirements:

• Operating temperature range encompassing -30°C to 85°C
• IP67 ingress protection for sealed applications

Substitute parts must satisfy all mechanical compatibility requirements and meet or exceed the electrical and environmental specifications of the main part.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: C&K 7201TCWCPES2

The 7201TCWCPES2 is the primary substitute for the obsolete 7201TCWCKES2. Both parts share identical electrical ratings, mechanical dimensions, and panel mount specifications. The 7201TCWCPES2 is currently in active production status with RoHS compliance and REACH affected designation, making it suitable for new designs and ongoing production support. The transition from satin chrome actuator (7201TCWCKES2) to epoxy sealed terminals (7201TCWCPES2) represents a manufacturing evolution within the same product series.

Alternative Substitutes: 34ADP18T7M2QT and A223T1TCB

The Grayhill 34ADP18T7M2QT and Electroswitch A223T1TCB are functionally compatible alternatives with higher electrical ratings. Both parts exceed the voltage and current requirements of the main part and maintain identical mechanical mounting specifications. The 34ADP18T7M2QT provides significantly higher current capacity (5A) and AC voltage rating (125V), suitable for applications requiring design margin. The A223T1TCB offers moderate electrical rating increases (0.5VA at 28V) with extended operating temperature range to 90°C.

Selection between alternatives depends on application requirements: choose the direct equivalent 7201TCWCPES2 for form-fit-function replacement; select 34ADP18T7M2QT or A223T1TCB only when higher electrical ratings or extended temperature performance are required.

Frequently Asked Questions (FAQ)

Q: Can the 7201TCWCPES2 directly replace the 7201TCWCKES2 without design modification?

A: Yes. The 7201TCWCPES2 maintains identical electrical ratings (0.4VA at 20V AC/DC), mechanical dimensions (11.91mm panel cutout, 15/32-32 bushing thread), actuator specifications (17.45mm standard round), and termination style (PC pin). Both parts are DPDT On-On configuration with 100,000 cycle electrical life. The primary difference is product status (active vs. obsolete) and terminal sealing method (epoxy sealed vs. satin chrome).

Q: Are the Grayhill 34ADP18T7M2QT and Electroswitch A223T1TCB suitable for direct replacement?

A: These parts are mechanically compatible but electrically over-specified. Both maintain the required panel mount configuration, bushing thread, and actuator dimensions. However, the 34ADP18T7M2QT provides 5A current capacity and 125V AC rating, while the A223T1TCB provides 0.5VA at 28V. Use these alternatives only when application requirements demand higher electrical ratings or when the direct equivalent is unavailable.

Q: What are the mechanical compatibility requirements for substitution?

A: All substitute parts must feature panel mount configuration with circular 11.91mm diameter cutout, 15/32-32 bushing thread, standard round actuator with 17.45mm length, and PC pin termination. These parameters ensure physical fit within existing panel assemblies and connector compatibility.

Q: Does the 7201TCWCPES2 maintain the same ingress protection rating?

A: Yes. The 7201TCWCPES2 retains IP67 ingress protection (dust tight, waterproof) identical to the 7201TCWCKES2, suitable for sealed applications in industrial environments.

Q: What is the significance of RoHS compliance differences?

A: The 7201TCWCKES2 is RoHS non-compliant, while the 7201TCWCPES2 is RoHS compliant. For new designs or applications subject to RoHS regulations, the 7201TCWCPES2 is the appropriate selection. Existing systems using the obsolete part may continue operation without modification.

Q: How do electrical life ratings compare among substitute options?

A: The 7201TCWCKES2 and 7201TCWCPES2 both specify 100,000 electrical cycles. The A223T1TCB provides 60,000 cycles, and the 34ADP18T7M2QT provides 40,000 cycles. For applications requiring maximum cycle life, the direct equivalent 7201TCWCPES2 is preferred.
