C&K 7105T1CWCKE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7105T1CWCKE 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 momentary-off-momentary (Mom-Off-Mom) switching function with IP67 ingress protection and epoxy-sealed terminals for harsh environment applications. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105T1CWCKE 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 (Panel Mount)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 11.91mm Dia)
• Ingress protection rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)

The C&K 7105T1CWCPE qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The 7105T1CWCPE is the appropriate substitute for the obsolete 7105T1CWCKE. Both components maintain identical electrical performance specifications and mechanical compatibility. The 7105T1CWCPE offers the advantage of active product status with current manufacturing support and documented inventory availability (840 Pcs). Both parts satisfy RoHS compliance requirements and carry equivalent environmental certifications. The substitution presents no functional or performance degradation for applications requiring SPDT toggle switching at the specified voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Can the 7105T1CWCPE be used as a direct replacement for the 7105T1CWCKE?

A: Yes. Both components share identical electrical ratings (0.4VA at 20V AC/DC), circuit configuration (SPDT), switch function (Mom-Off-Mom), mechanical dimensions, and environmental specifications (IP67, -30°C to 85°C operating range). Panel cutout dimensions and termination style are identical, enabling direct substitution without circuit or mechanical redesign.

Q: What is the primary difference between these two parts?

A: The 7105T1CWCKE is classified as obsolete, while the 7105T1CWCPE maintains active product status with ongoing manufacturing support. The 7105T1CWCPE is the current production equivalent within the C&K 7000 series.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant and carry EAR99 export classification. The 7105T1CWCKE is RoHS3 compliant, while the 7105T1CWCPE is RoHS compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity rating and are unaffected or affected by REACH regulations respectively, but this does not impact functional substitution.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in circuit configuration (SPDT), switch function (Mom-Off-Mom), current/voltage ratings (0.4VA at 20V AC/DC), mounting type (Panel Mount), termination style (PC Pin), panel cutout dimensions (11.91mm circular), ingress protection (IP67), operating temperature range (-30°C to 85°C), and electrical life (40,000 cycles).

Q: Is the panel cutout dimension critical for substitution?

A: Yes. The circular 11.91mm panel cutout dimension and 15/32-32 bushing thread are mechanical requirements for panel-mount installation. Any substitute must maintain these specifications to ensure proper mechanical fit and environmental sealing.
