Equivalent & Substitute Parts for C&K 7103SPYCKE Toggle Switch SPDT

Part Overview

The C&K 7103SPYCKE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features anti-rotation actuator design, epoxy sealed terminals, and operates across -30°C to 85°C temperature range with 40,000 electrical cycle life.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103SPYCKE is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V (AC and DC)
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Actuator type (Anti-Rotation vs. Standard Round)
• Actuator length (within 10.41mm to 10.67mm range)
• Actuator material composition (Brass with different plating)
• Electrical life (6,000 to 40,000 cycles)
• Product status (Active substitutes acceptable for obsolete main part)
• RoHS and REACH compliance status

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred): The C&K 7103SPYCPE is the primary substitute for the obsolete 7103SPYCKE. Both components share identical electrical specifications, mechanical dimensions, and actuator design. The 7103SPYCPE maintains active product status with higher inventory availability (1028 pcs vs. 872 pcs). RoHS compliance is maintained, though REACH status differs (Affected vs. Unaffected). This substitution requires no design modifications.

Cross-Manufacturer Alternatives: The TE Connectivity 1-1825137-5 and Grayhill 34ASP31B1M2RT meet all mandatory electrical and mechanical parameters. Both are active products with confirmed inventory. The TE Connectivity part features a standard round actuator and reduced electrical life (6,000 cycles vs. 40,000 cycles), which may impact applications requiring extended cycle durability. The Grayhill part maintains 40,000 cycle electrical life and is suitable for direct substitution with consideration for actuator type differences.

Compliance Considerations: All substitute parts maintain MSL 1 rating and operate within the specified temperature range. RoHS3 compliance is confirmed for C&K 7103SPYCPE and TE Connectivity 1-1825137-5. REACH status varies across manufacturers; applications subject to REACH regulations should verify compliance requirements with specific supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can the 7103SPYCPE directly replace the obsolete 7103SPYCKE without design changes? A: Yes. The 7103SPYCPE is electrically and mechanically identical to the 7103SPYCKE. Panel cutout dimensions, bushing thread specifications, and PC pin termination are unchanged. No PCB or mechanical redesign is required.

Q: What is the difference between anti-rotation and standard round actuators? A: The anti-rotation actuator (7103SPYCKE and 7103SPYCPE) includes a feature preventing unintended rotation during installation. The standard round actuator (TE Connectivity and Grayhill parts) lacks this feature. Both actuator types are mechanically compatible with the specified 6.35mm circular panel cutout and 1/4-40 bushing thread.

Q: Why does the TE Connectivity 1-1825137-5 have lower electrical life (6,000 cycles vs. 40,000 cycles)? A: Electrical life rating reflects design specifications for each manufacturer's switch series. The TE Connectivity Gemini A series is rated for 6,000 cycles under the specified 0.4VA load. Applications requiring extended cycle life should prioritize the C&K 7103SPYCPE or Grayhill 34ASP31B1M2RT, both rated for 40,000 cycles.

Q: Are all substitute parts available in the same packaging format? A: The C&K 7103SPYCPE and Grayhill 34ASP31B1M2RT are available in bulk packaging. The TE Connectivity 1-1825137-5 is specified as bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: What compliance certifications apply to these toggle switches? A: All parts are MSL 1 (Unlimited moisture sensitivity level). RoHS3 compliance is confirmed for C&K 7103SPYCPE and TE Connectivity 1-1825137-5. REACH status varies: C&K 7103SPYCKE is REACH Unaffected; C&K 7103SPYCPE and TE Connectivity 1-1825137-5 are REACH Affected; Grayhill 34ASP31B1M2RT is REACH Unaffected. Verify REACH compliance requirements for your specific application and supply chain.

Q: Can these switches operate reliably at the temperature extremes of -30°C to 85°C? A: Yes. All listed parts are rated for continuous operation across the -30°C to 85°C temperature range. This specification applies to both electrical performance and mechanical actuator function.
