C&K 7105L41CWCKE22 Toggle Switch SPDT - Equivalent & Substitute Parts

Part Overview

The C&K 7105L41CWCKE22 is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This component features a momentary-off-momentary (Mom-Off-Mom) switch function with IP67 ingress protection, making it suitable for sealed applications requiring dust and water resistance. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for direct replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105L41CWCKE22 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Circuit configuration (SPDT), switch function (Mom-Off-Mom), current rating (0.4VA AC/DC), and voltage ratings (20V AC/DC) must be identical
• Mechanical Compatibility: Mounting type (panel mount), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), termination style (PC pin), and actuator specifications (flat anti-rotation, 13.49mm length) must match exactly
• Environmental Specifications: Ingress protection (IP67), operating temperature range (-30°C to 85°C), and electrical life (40,000 cycles) must be maintained
• Physical Characteristics: Non-illuminated configuration and brass chrome-plated actuator material must be preserved

The substitute part 7105L41CWCPE22 meets all these criteria, differing only in product status (active vs. obsolete), terminal sealing method (epoxy sealed vs. standard), and regulatory compliance documentation (REACH affected vs. unaffected).

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105L41CWCPE22 is the direct functional equivalent for applications currently using the obsolete 7105L41CWCKE22. Both components are manufactured by C&K within the same 7000 series and maintain identical electrical ratings, mechanical dimensions, and environmental specifications.

The 7105L41CWCPE22 offers the advantage of active product status, ensuring continued availability and manufacturer support. The component features epoxy sealed terminals, which provides enhanced protection for the PC pin terminations compared to the standard configuration of the original part. Both parts maintain RoHS compliance and MSL Level 1 rating, suitable for standard storage and handling conditions without moisture sensitivity concerns.

Selection between these parts should be based on procurement requirements and supply chain considerations, as the substitute part's active status makes it the preferred choice for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7105L41CWCPE22 be used as a direct replacement for the 7105L41CWCKE22?

A: Yes. Both parts share identical electrical specifications (SPDT, Mom-Off-Mom, 0.4VA, 20V AC/DC), mechanical dimensions (6.35mm panel cutout, 1/4-40 bushing thread, PC pin termination), and environmental ratings (IP67, -30°C to 85°C operating range, 40,000 cycle electrical life). The substitute part is electrically and mechanically compatible for direct substitution.

Q: What is the difference between the black actuator feature and epoxy sealed terminals?

A: The original part (7105L41CWCKE22) specifies a black actuator as a distinguishing feature. The substitute part (7105L41CWCPE22) features epoxy sealed terminals, which provide additional environmental protection to the PC pin connections. Both parts maintain the same flat anti-rotation actuator design with 13.49mm length and brass chrome-plated material.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant and carry MSL Level 1 rating. The original part is ROHS3 compliant, while the substitute is listed as RoHS compliant. The substitute part is REACH affected, whereas the original is REACH unaffected. Both carry EAR99 ECCN classification and the same HTSUS code (8536.50.9065).

Q: What is the panel mounting configuration for these switches?

A: Both parts are panel-mount toggle switches with a circular 6.35mm diameter cutout and 1/4-40 bushing thread. The flat anti-rotation actuator prevents rotation during installation and operation. PC pin termination is used for circuit board connection.

Q: Is the IP67 rating maintained in the substitute part?

A: Yes. The 7105L41CWCPE22 maintains the same IP67 ingress protection rating (dust tight and waterproof) as the original 7105L41CWCKE22, making it suitable for sealed applications requiring environmental protection.
