C&K 7105SPH3WLE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7105SPH3WLE is a panel-mounted toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features momentary-off-momentary (Mom-Off-Mom) switching function with anti-rotation actuator and wire wrap termination. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for direct replacement in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105SPH3WLE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (5A AC/DC, 120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Anti-Rotation, 10.16mm length)
• Termination style (Wire Wrap)
• Panel interface dimensions (Circular 6.35mm Dia, 1/4-40 bushing thread)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 Cycles)
• Terminal sealing (Epoxy Sealed)

The C&K 7105SPH3WRE meets all substitution criteria as an active product within the same 7000 series, maintaining complete electrical and mechanical compatibility with the obsolete 7105SPH3WLE.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7105SPH3WRE is the direct substitute for the obsolete 7105SPH3WLE. Both parts are manufactured by C&K within the 7000 series and share identical electrical ratings, mechanical interfaces, and functional specifications. The 7105SPH3WRE is currently in active production status, ensuring availability and supply chain continuity.

Both parts maintain RoHS compliance and EAR99 export classification. The 7105SPH3WRE carries RoHS Compliant status while the original part is ROHS3 Compliant; both designations confirm lead-free construction and environmental regulatory adherence. REACH status differs between the parts but does not affect substitution eligibility for direct replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 7105SPH3WRE directly replace the 7105SPH3WLE in existing assemblies?

A: Yes. The 7105SPH3WRE maintains complete electrical and mechanical compatibility with the 7105SPH3WLE. All critical parameters including circuit configuration, current/voltage ratings, mounting dimensions, actuator specifications, and termination style are identical.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant designations?

A: Both designations confirm RoHS compliance and lead-free construction. ROHS3 refers to RoHS Directive 2011/65/EU as amended. Both parts meet environmental regulatory requirements for their respective markets.

Q: Are there any panel cutout or mounting modifications required when substituting the 7105SPH3WRE for the 7105SPH3WLE?

A: No modifications are required. Both parts feature identical panel cutout dimensions (Circular 6.35mm Dia) and bushing thread specifications (1/4-40), enabling direct mechanical interchange.

Q: What is the significance of the Mom-Off-Mom switch function?

A: Mom-Off-Mom indicates momentary-on-off-momentary operation. The switch returns to the center (off) position when released from either direction, requiring continuous actuation to maintain contact in either pole position.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the 7105SPH3WLE and 7105SPH3WRE operate across the identical temperature range of -30°C to 85°C, ensuring thermal compatibility in equivalent applications.
