C&K 7101P4YCME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101P4YCME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The switch features a flat anti-rotation actuator, epoxy sealed terminals, and operates across a temperature range of -30°C to 85°C with an electrical life of 100,000 cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101P4YCME are identified based on electrical and mechanical compatibility within the following critical parameters:

Electrical Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage rating - AC: 120V minimum
• Voltage rating - DC: 28V
• Operating temperature range: -30°C ~ 85°C minimum

Mechanical Compatibility Criteria:

• Mounting type: Panel Mount
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40

Compliance Criteria:

• RoHS compliance status
• REACH status
• ECCN classification

Parts meeting these parameters are classified as direct substitutes. Parts with minor deviations in non-critical parameters (such as actuator type or electrical life) are classified as similar substitutes, with specific parameter differences noted.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute: C&K 7101P4YCSE

The 7101P4YCSE is a direct substitute for the obsolete 7101P4YCME. Both parts share identical electrical ratings, mechanical dimensions, and actuator specifications. The 7101P4YCSE maintains active product status, ensuring availability and supply chain continuity. Both parts are ROHS3 compliant and carry the same ECCN classification (EAR99). The primary difference is REACH status: the 7101P4YCSE is REACH Affected, whereas the original part is REACH Unaffected. This distinction must be evaluated against applicable regulatory requirements for the end application.

Similar Substitute: Grayhill Inc. 34ASP12B3M2QT

The 34ASP12B3M2QT is a similar substitute with the following considerations:

• Electrical specifications are equivalent: 5A rating at 120V AC (5V higher than original) and 28V DC
• Mechanical mounting is compatible: identical panel cutout dimensions and bushing thread
• Actuator type differs: Standard Round versus Flat Anti-Rotation, with a length increase of 0.51mm (6.86mm versus 6.35mm)
• Electrical life is reduced: 40,000 cycles versus 100,000 cycles
• Both parts are ROHS3 compliant and REACH Unaffected

The 34ASP12B3M2QT is suitable for applications where the increased AC voltage rating and different actuator geometry do not present design constraints, and where the reduced electrical life cycle meets operational requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7101P4YCSE be used as a direct replacement for the 7101P4YCME?

A: Yes. The 7101P4YCSE is a direct substitute. Both parts have identical electrical ratings (5A, 120V AC, 28V DC), mechanical dimensions, and actuator specifications. The primary consideration is REACH compliance status, which differs between the two parts.

Q: What are the key differences between the C&K 7101P4YCSE and the Grayhill 34ASP12B3M2QT?

A: The primary differences are: (1) Actuator type and length—the Grayhill part uses a Standard Round actuator at 6.86mm versus the Flat Anti-Rotation at 6.35mm; (2) Electrical life—40,000 cycles versus 100,000 cycles; (3) AC voltage rating—125V versus 120V. Mechanical mounting and termination are compatible.

Q: Is the Grayhill 34ASP12B3M2QT suitable for high-cycle applications?

A: The 34ASP12B3M2QT has an electrical life rating of 40,000 cycles, compared to 100,000 cycles for the C&K parts. Applications requiring extended cycle life should use the C&K 7101P4YCSE.

Q: What is the impact of the different actuator types on panel design?

A: The C&K parts use a Flat Anti-Rotation actuator at 6.35mm length, while the Grayhill part uses a Standard Round actuator at 6.86mm length. The 0.51mm length difference and different actuator geometry may affect operator feel and panel aesthetics. Panel cutout dimensions remain compatible at 6.35mm diameter.

Q: Are all three parts RoHS compliant?

A: Yes. The 7101P4YCME and 34ASP12B3M2QT are ROHS3 compliant. The 7101P4YCSE is RoHS compliant. All three parts meet RoHS requirements.

Q: What is the significance of REACH status differences?

A: The 7101P4YCME and 34ASP12B3M2QT are REACH Unaffected, while the 7101P4YCSE is REACH Affected. REACH Affected status indicates the part contains substances of concern and requires compliance documentation. Applications subject to REACH regulations must account for this distinction during component selection.
