E103SD1AV3PE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The E103SD1AV3PE is an active production toggle switch manufactured by C&K, configured as a Single Pole Double Throw (SPDT) with On-Off-On switching function. This through-hole, right-angle vertical mount component is designed for applications requiring low-voltage switching up to 20V AC/DC at 0.4VA capacity. The part features epoxy sealed terminals and IP57 ingress protection, making it suitable for environments requiring dust and moisture resistance. Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters while remaining in active production status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E103SD1AV3PE are identified based on the following critical parameters that determine functional compatibility:

• Circuit Configuration: SPDT topology must be maintained
• Switch Function: On-Off-On operation required
• Mounting Type: Through hole, right-angle vertical orientation
• Termination Style: PC pin termination
• Actuator Type: Standard round actuator
• Operating Temperature Range: -30°C to 85°C minimum
• Electrical Life: 40,000 cycles minimum
• Product Status: Active production status
• RoHS Compliance: ROHS3 compliant

The E103SD1AV3PE substitute 100SP3T1B4M7QE from E-Switch maintains these core functional and mechanical parameters. While the substitute exhibits higher current and voltage ratings (5A at 120V AC / 28V DC versus 0.4VA at 20V), these represent enhanced electrical capabilities that do not compromise compatibility in applications designed for the original part's specifications. Both components share identical circuit topology, switching function, mounting configuration, and environmental operating range.

Parameter Comparison

Engineering Selection Recommendations

Both the E103SD1AV3PE and 100SP3T1B4M7QE maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The E103SD1AV3PE is the primary specification when application requirements are limited to 20V and 0.4VA operation. The 100SP3T1B4M7QE substitute from E-Switch is suitable for applications where the original part is unavailable, provided the circuit design operates within the original part's electrical envelope (20V maximum, 0.4VA maximum). The 2.29mm difference in actuator length should be evaluated against panel cutout and mechanical clearance constraints in the target application. Both components feature identical circuit topology, switching function, and environmental operating range, supporting direct functional substitution in compatible designs.

Frequently Asked Questions (FAQ)

Q: Can the 100SP3T1B4M7QE replace the E103SD1AV3PE in all applications?

A: The 100SP3T1B4M7QE maintains functional compatibility for applications operating within the E103SD1AV3PE electrical specifications (20V maximum, 0.4VA maximum). The substitute's higher ratings do not affect performance in lower-power circuits. Mechanical clearance must be verified due to the 2.29mm actuator length difference.

Q: What is the significance of the higher current and voltage ratings on the substitute part?

A: The 100SP3T1B4M7QE is rated for 5A at 120V AC and 28V DC, compared to the E103SD1AV3PE's 0.4VA at 20V. These higher ratings indicate enhanced electrical capability but do not change the switching function or circuit topology. Applications designed for the original part's lower ratings remain fully compatible.

Q: Are there mechanical compatibility concerns between these parts?

A: Both components share identical mounting type (through hole, right-angle vertical), termination style (PC pin), and actuator type (standard round). The actuator length difference of 2.29mm (12.70mm versus 10.41mm) requires verification against panel cutout dimensions and mechanical clearance in the specific application.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the E103SD1AV3PE and 100SP3T1B4M7QE are ROHS3 compliant and maintain active production status, ensuring regulatory alignment and long-term component availability.

Q: What is the electrical life expectancy for both parts?

A: Both components are rated for 40,000 electrical cycles, providing identical operational longevity under normal switching conditions.
