C&K 7101L41CWCLE2 Toggle Switch SPDT — Equivalent & Substitute Parts

Part Overview

The C&K 7101L41CWCLE2 is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications. The switch features IP67 ingress protection, non-illuminated operation, and PC pin termination suitable for industrial control and aerospace applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101L41CWCLE2 is determined by strict alignment across the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A minimum, AC/DC)
• Voltage rating (120V AC minimum; 28V DC minimum)
• Mounting type (Panel Mount)
• Panel cutout dimensions (6.35mm circular)
• Bushing thread specification (1/4-40)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C minimum)

Direct Manufacturer Substitute: The C&K 7101L41CWRE2 is a direct equivalent from the same manufacturer and series, differing only in product status (Active vs. Obsolete) and terminal sealing method (Epoxy Sealed vs. standard).

Cross-Manufacturer Substitute: The Grayhill Inc. 34ASP11B9M2QT meets all primary electrical and mechanical criteria but introduces variations in actuator geometry, electrical life rating, and ingress protection specification that must be evaluated for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

C&K 7101L41CWRE2 (Recommended Direct Replacement)

The 7101L41CWRE2 is the primary substitute for the obsolete 7101L41CWCLE2. Both components are from the C&K 7000 series and share identical electrical ratings, mechanical dimensions, and operating specifications. The 7101L41CWRE2 maintains Active product status, ensuring continued availability and supply chain support. The only functional difference is terminal sealing (Epoxy Sealed vs. standard), which enhances environmental protection. RoHS compliance is maintained. This part is suitable for direct substitution in all applications where the original component was specified.

Grayhill Inc. 34ASP11B9M2QT (Cross-Manufacturer Alternative)

The 34ASP11B9M2QT meets all primary electrical and mechanical substitution criteria and maintains Active product status. However, three parameter variations require application-level evaluation:

• Electrical life is rated at 40,000 cycles versus 100,000 cycles for the C&K parts, reducing operational longevity by 60 percent.
• Ingress protection is not specified, whereas the original component is rated IP67.
• Actuator geometry differs (Standard Round, 10.41mm length versus Flat Anti-Rotation, 13.49mm length), which may affect panel mounting clearance and operator interface feel.

The 34ASP11B9M2QT is suitable only for applications where reduced electrical life and unspecified ingress protection do not compromise system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7101L41CWRE2 be used as a direct replacement for the 7101L41CWCLE2?

A: Yes. Both components are from the C&K 7000 series and share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (SPDT), mechanical dimensions (6.35mm panel cutout, 1/4-40 bushing), and operating temperature range (-30°C to 85°C). The 7101L41CWRE2 is Active and available, making it the recommended substitute for the obsolete 7101L41CWCLE2.

Q: What are the key differences between the C&K 7101L41CWRE2 and the Grayhill 34ASP11B9M2QT?

A: Both parts meet the core electrical and mechanical requirements. The primary differences are: (1) Electrical life — C&K rated at 100,000 cycles versus Grayhill at 40,000 cycles; (2) Ingress protection — C&K rated IP67 versus Grayhill not specified; (3) Actuator design — C&K uses Flat Anti-Rotation (13.49mm) versus Grayhill uses Standard Round (10.41mm). These differences may affect long-term reliability, environmental sealing, and panel mounting fit.

Q: Is the Grayhill 34ASP11B9M2QT suitable for applications requiring IP67 protection?

A: The 34ASP11B9M2QT does not specify an ingress protection rating. Applications requiring IP67 (Dust Tight, Waterproof) protection should use the C&K 7101L41CWRE2 or 7101L41CWCLE2 to ensure compliance with environmental specifications.

Q: Does the difference in actuator length (13.49mm vs. 10.41mm) affect panel mounting?

A: Actuator length affects operator reach and panel clearance. The C&K parts feature a longer actuator (13.49mm, Flat Anti-Rotation design), while the Grayhill part has a shorter actuator (10.41mm, Standard Round design). Panel cutout dimensions are identical (6.35mm circular, 1/4-40 bushing), but the difference in actuator geometry and length may require physical evaluation for specific panel installations.

Q: What is the impact of the 60 percent reduction in electrical life for the Grayhill part?

A: The Grayhill 34ASP11B9M2QT is rated for 40,000 cycles versus 100,000 cycles for the C&K parts. In applications with frequent switching cycles, this reduced rating may result in earlier component wear and potential failure. Applications requiring extended operational life or high-cycle switching should use the C&K 7101L41CWRE2.

Q: Are all substitute parts RoHS compliant?

A: Yes. The C&K 7101L41CWCLE2 and 7101L41CWRE2 are ROHS3 Compliant. The Grayhill 34ASP11B9M2QT is also ROHS3 Compliant. All three parts meet RoHS requirements for hazardous substance restrictions.
