Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105L41CWCKE2 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type and mechanical interface (Panel Mount, 1/4-40 bushing thread, 6.35mm circular cutout)
• Actuator specifications (Flat Anti-Rotation, 13.49mm length)
• Termination style (PC Pin)
• Ingress protection rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles)

The C&K 7105L41CWCPE2 meets all substitution criteria as a direct equivalent within the 7000 series, with the primary distinction being active product status and terminal sealing design.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105L41CWCPE2 is the direct functional equivalent for applications currently specified with the 7105L41CWCKE2. The substitute part maintains identical electrical performance, mechanical interface, and environmental ratings. The primary advantage of the 7105L41CWCPE2 is its active product status, ensuring continued availability and supply chain support. Both parts carry equivalent compliance certifications (RoHS, EAR99 export classification, MSL 1), with the substitute featuring epoxy-sealed terminals as a design enhancement over the original black actuator configuration. Selection between these parts should be based on supply availability and long-term procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7105L41CWCPE2 be used as a direct replacement for the 7105L41CWCKE2 in existing designs?

A: Yes. Both parts share identical electrical ratings (0.4VA at 20V AC/DC), circuit configuration (SPDT Mom-Off-Mom), mechanical mounting interface (1/4-40 bushing, 6.35mm circular cutout), and environmental specifications (IP67, -30°C to 85°C operating range). No design modifications are required.

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

A: The 7105L41CWCKE2 features a black actuator, while the 7105L41CWCPE2 incorporates epoxy-sealed terminals. Both designs maintain the same functional performance and IP67 ingress protection rating. The epoxy sealing in the substitute part represents a design refinement for enhanced terminal protection.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant and carry identical export classifications (EAR99). The 7105L41CWCKE2 is RoHS3 compliant, while the 7105L41CWCPE2 is RoHS compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity levels and are subject to the same HTSUS classification (8536.50.9065).

Q: Why is the 7105L41CWCKE2 classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this specific part number. The 7105L41CWCPE2 remains in active production within the same 7000 series, providing continuity for applications requiring SPDT panel-mount toggle switches with these specifications.

Q: Are the panel cutout dimensions identical for both parts?

A: Yes. Both parts require a circular 6.35mm diameter cutout with a 1/4-40 bushing thread, ensuring mechanical interchangeability in panel-mount applications.
