ES23MCKE Equivalent & Substitute Parts

Part Overview

The ES23MCKE is a slide switch manufactured by C&K, featuring DPDT (Double Pole Double Throw) configuration with On-Off-On switching function. This component is rated for 0.4VA at 20V AC/DC and is designed for through-hole mounting applications. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES23MCKE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (DPDT required)
• Switch function (On-Off-On required)
• Mounting type (Through Hole required)
• Termination style (PC Pin required)
• Contact finish (Gold preferred for compatibility)

Secondary Compatibility Criteria:

• Current rating must equal or exceed 0.4VA
• Voltage rating must equal or exceed 20V (AC/DC)
• Operating temperature range must encompass or exceed -30°C to 85°C
• Mechanical and electrical life specifications

Two substitute parts are identified based on these parameters:

1. ES23MCBE (C&K): Direct manufacturer equivalent with identical electrical and mechanical specifications. Active product status with improved compliance profile.

2. ASE2E-2M-10-Z (Nidec Components Corporation): Similar DPDT slide switch with higher voltage and current ratings. Meets primary compatibility criteria with enhanced electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

ES23MCBE (Recommended Primary Substitute): ES23MCBE is the direct equivalent from C&K with identical electrical and mechanical specifications to the ES23MCKE. This part maintains the same current rating (0.4VA), voltage rating (20V AC/DC), actuator length (3.07mm), and operational life cycles (40,000 cycles). The ES23MCBE is currently in active production status with ROHS3 compliance and REACH affected designation, providing superior supply chain continuity compared to the obsolete ES23MCKE. Packaging is supplied in tray format with 1232 units available in inventory.

ASE2E-2M-10-Z (Alternative Substitute): ASE2E-2M-10-Z from Nidec Components Corporation meets all primary compatibility criteria as a DPDT On-Off-On slide switch with through-hole PC pin termination. This part provides enhanced electrical performance with 60V voltage rating and 50mA current capacity, exceeding the ES23MCKE specifications. However, electrical life is rated at 10,000 cycles compared to 40,000 cycles for the ES23MCKE, and the minimum operating temperature is -20°C versus -30°C for the original part. This substitute is suitable for applications where higher voltage margin is beneficial and lower cycle life is acceptable. The part is ROHS3 compliant with 4515 units available in inventory.

Frequently Asked Questions (FAQ)

Q: Can ES23MCBE be used as a direct replacement for ES23MCKE? A: Yes. ES23MCBE is a direct equivalent with identical circuit configuration (DPDT), switch function (On-Off-On), current rating (0.4VA), voltage rating (20V AC/DC), actuator dimensions (3.07mm), and operational life specifications (40,000 cycles). The primary difference is product status (active versus obsolete) and improved regulatory compliance (ROHS3 compliant).

Q: What are the limitations of ASE2E-2M-10-Z as a substitute? A: ASE2E-2M-10-Z has a reduced electrical life rating of 10,000 cycles compared to 40,000 cycles for the ES23MCKE. The minimum operating temperature is -20°C instead of -30°C. Current rating is 50mA, which is lower than the 0.4VA specification. These parameters must be evaluated against application requirements before selection.

Q: Are there packaging differences between the substitute parts? A: ES23MCKE was supplied with unspecified packaging. ES23MCBE is supplied in tray packaging. ASE2E-2M-10-Z is also supplied in tray packaging. Packaging format should be confirmed with procurement requirements for assembly and handling processes.

Q: What compliance certifications apply to each part? A: ES23MCKE is RoHS non-compliant and REACH unaffected. ES23MCBE is ROHS3 compliant and REACH affected. ASE2E-2M-10-Z is ROHS3 compliant. All three parts carry ECCN classification EAR99 and HTSUS code 8536.50.9050.

Q: Can ASE2E-2M-10-Z be used in applications requiring -30°C minimum operating temperature? A: No. ASE2E-2M-10-Z has a minimum operating temperature of -20°C. Applications requiring -30°C operation must use ES23MCKE or ES23MCBE.

Q: Which substitute part should be selected for new designs? A: ES23MCBE is recommended for new designs as it provides direct electrical and mechanical equivalence to ES23MCKE with active product status and improved regulatory compliance. ASE2E-2M-10-Z should be considered only when higher voltage margin (60V) is a design requirement and reduced electrical life (10,000 cycles) is acceptable.
