C&K 7101T2PCKE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101T2PCKE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The 7101T2 series provides reliable switching performance with epoxy-sealed terminals and brass chrome-plated actuators suitable for industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101T2PCKE is determined by the following critical parameters:

Mechanical Compatibility:

• Panel cutout diameter: 11.91mm (circular)
• Bushing thread: 15/32-32
• Mounting type: Panel Mount
• Termination style: PC Pin

Electrical Compatibility:

• Circuit: SPDT
• Switch function: On-On
• Operating temperature range: -30°C to 85°C
• Actuator material: Brass, Chrome Plated

Functional Parameters:

• Current rating must equal or exceed 0.4VA
• Voltage rating (AC and DC) must equal or exceed 20V

The C&K 7101T2PCPE represents a direct manufacturer upgrade within the same 7000 series, maintaining identical mechanical and electrical specifications while transitioning from obsolete to active product status. The Grayhill 34ASP17T7M2QT and 34ASP18T7M2QT parts satisfy mechanical compatibility requirements and exceed electrical performance specifications, though they feature different actuator geometries and higher electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: C&K 7101T2PCPE

The 7101T2PCPE is the direct successor to the 7101T2PCKE within the C&K 7000 series. This part maintains identical mechanical and electrical specifications, including panel cutout dimensions, bushing thread, actuator geometry, and electrical ratings. The transition from obsolete to active product status ensures long-term availability and supply chain continuity. Both parts carry RoHS compliance certifications appropriate for their respective regulatory environments.

Secondary Recommendation: Grayhill 34ASP17T7M2QT or 34ASP18T7M2QT

The Grayhill 34ASP series parts satisfy all mechanical compatibility requirements and provide superior electrical performance with 5A current ratings and 125V AC voltage ratings. These parts accommodate the 11.91mm panel cutout and 15/32-32 bushing thread specifications. Selection between 34ASP17T7M2QT (12.37mm actuator length) and 34ASP18T7M2QT (17.45mm actuator length) depends on panel depth and actuator accessibility requirements. Both parts are active products with RoHS compliance and REACH unaffected status.

Compliance Considerations:

All substitute parts maintain RoHS compliance. The 7101T2PCPE carries REACH affected status, while the Grayhill alternatives remain REACH unaffected. Applications subject to REACH restrictions should prioritize the Grayhill 34ASP series or confirm REACH compliance requirements with procurement.

Frequently Asked Questions (FAQ)

Q: Can the 7101T2PCPE directly replace the 7101T2PCKE without panel modifications?

A: Yes. The 7101T2PCPE maintains identical panel cutout diameter (11.91mm), bushing thread (15/32-32), and actuator length (15.49mm). No mechanical modifications to the panel assembly are required.

Q: What are the key differences between the C&K 7101T2PCPE and Grayhill 34ASP series?

A: The primary differences are actuator geometry and electrical life rating. The C&K 7101T2PCPE features a flat anti-rotation actuator with 100,000-cycle electrical life. The Grayhill 34ASP series uses standard round actuators with 40,000-cycle electrical life. Both maintain compatible panel mounting dimensions and PC pin termination.

Q: Are the Grayhill 34ASP17T7M2QT and 34ASP18T7M2QT interchangeable?

A: Both parts are mechanically compatible with the 7101T2PCKE panel cutout and bushing thread. The primary distinction is actuator length: 12.37mm for the 34ASP17T7M2QT and 17.45mm for the 34ASP18T7M2QT. Selection depends on available panel depth and operator accessibility requirements.

Q: Do all substitute parts meet the original 0.4VA, 20V electrical specification?

A: The C&K 7101T2PCPE matches the original specification exactly. The Grayhill 34ASP series parts exceed the original specification with 5A current rating and 125V AC voltage rating, making them suitable for applications requiring higher electrical performance.

Q: What is the impact of REACH status on part selection?

A: REACH affected status (7101T2PCPE) indicates the part is subject to REACH chemical substance restrictions. Applications in REACH-regulated markets should confirm compliance requirements. The Grayhill 34ASP series maintains REACH unaffected status, providing regulatory flexibility for international applications.

Q: Are PC pin terminations compatible across all substitute parts?

A: Yes. All substitute parts use PC pin termination style, ensuring compatibility with existing PCB footprints and connector interfaces designed for the 7101T2PCKE.
