C&K 7103K2CKE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7103K2CKE is a toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features a locking lever actuator and is designed for On-Off-On switching applications. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing procurement and system maintenance. The 7103K2CPE serves as a direct functional equivalent with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103K2CKE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Electrical ratings (0.4VA at 20V AC/DC)
• Mechanical interface (Panel mount, 6.35mm circular cutout, 1/4-40 bushing thread)
• Actuator specifications (Locking lever, 17.88mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles)

The 7103K2CPE meets all these criteria and is classified as a direct substitute. Both parts share the same base product number (7103K2) and are manufactured by C&K within the 7000 series.

Parameter Comparison

Engineering Selection Recommendations

The 7103K2CPE is the appropriate substitute for the obsolete 7103K2CKE. Both parts are electrically and mechanically identical across all functional parameters. The primary distinction is product status and regulatory compliance:

The 7103K2CKE is obsolete and no longer actively manufactured. The 7103K2CPE maintains active product status with current manufacturing support.

The 7103K2CPE is RoHS Compliant, whereas the 7103K2CKE is RoHS non-compliant. For applications subject to RoHS directives, the 7103K2CPE is the required selection.

The 7103K2CPE is REACH Affected, indicating compliance with REACH regulations. The 7103K2CKE is REACH Unaffected.

For new designs and ongoing procurement, the 7103K2CPE is the standard selection. For legacy system maintenance where the original 7103K2CKE is specified, the 7103K2CPE provides direct functional replacement with enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 7103K2CPE directly replace the 7103K2CKE in existing applications?

A: Yes. Both parts share identical electrical ratings (0.4VA at 20V AC/DC), circuit configuration (SPDT), switch function (On-Off-On), and mechanical interface specifications (panel mount, 6.35mm cutout, 1/4-40 bushing thread). The actuator specifications, termination style, and operating temperature range are identical. No circuit modifications or mechanical redesign is required.

Q: What is the difference between these two parts?

A: The 7103K2CKE is obsolete; the 7103K2CPE is active. The 7103K2CPE is RoHS Compliant and REACH Affected, while the 7103K2CKE is RoHS non-compliant and REACH Unaffected. Functionally and mechanically, the parts are equivalent.

Q: Are there packaging differences between these parts?

A: The 7103K2CKE packaging is not specified. The 7103K2CPE is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What parameters determine substitution eligibility for this switch?

A: Substitution is based on SPDT circuit configuration, On-Off-On switch function, 0.4VA current rating at 20V AC/DC, panel-mount mechanical interface with 6.35mm circular cutout and 1/4-40 bushing thread, locking lever actuator at 17.88mm length, PC Pin termination, -30°C to 85°C operating temperature range, and 40,000-cycle electrical life.

Q: Is the 7103K2CPE suitable for RoHS-compliant applications?

A: Yes. The 7103K2CPE is RoHS Compliant. The 7103K2CKE is RoHS non-compliant and is not suitable for applications requiring RoHS compliance.
