ES03MCBE Equivalent & Substitute Parts

Part Overview

The ES03MCBE is an active slide switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuit 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 switch incorporates epoxy sealed terminals with IP57 protection and operates across a temperature range of -30°C to 85°C. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time considerations, or specific application requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES03MCBE is determined by the following critical parameters:

Circuit configuration must remain SPDT with On-Off-On switching function to maintain functional equivalence. The substitute part ASE1E-2M-10-Z meets this requirement.

Mounting type and termination style must be through-hole with PC pin configuration to ensure mechanical and electrical compatibility with existing PCB designs.

Contact finish specification (gold) ensures reliable electrical performance and corrosion resistance in the intended application environment.

Voltage and current ratings of substitute parts must equal or exceed the original specification. The ASE1E-2M-10-Z provides 60V AC/DC rating and 50mA current capacity, both exceeding the ES03MCBE requirements of 20V and 0.4VA, establishing compatibility for lower-stress applications.

Operating temperature range must support the application environment. The ASE1E-2M-10-Z operates from -20°C to 85°C, covering the upper portion of the ES03MCBE range (-30°C to 85°C).

RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ensure regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ASE1E-2M-10-Z from Nidec Components Corporation qualifies as a functional substitute for the ES03MCBE based on matching circuit topology, switching function, mounting configuration, and regulatory compliance status.

Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and storage requirements. Both are active products with established supply chains.

The ASE1E-2M-10-Z provides electrical performance headroom with 60V and 50mA ratings compared to the ES03MCBE specification of 20V and 0.4VA, making it suitable for applications operating within the original voltage and current parameters.

The ASE1E-2M-10-Z operates across -20°C to 85°C, which covers the upper temperature range of the ES03MCBE. Applications requiring the full -30°C lower temperature limit of the ES03MCBE should not substitute with the ASE1E-2M-10-Z.

The ASE1E-2M-10-Z specifies 10,000 electrical life cycles compared to 40,000 cycles for the ES03MCBE. Applications requiring extended cycle life should evaluate this difference against actual duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the ASE1E-2M-10-Z directly replace the ES03MCBE in existing designs?

A: Direct replacement is possible from a mechanical and electrical standpoint. Both components feature identical through-hole PC pin termination, SPDT On-Off-On configuration, and gold-plated contacts. Verify that your application operates within the -20°C to 85°C temperature range and does not exceed 10,000 electrical cycles if cycle life is critical.

Q: What are the key differences between these two switches?

A: The primary differences are voltage/current rating headroom (60V/50mA versus 20V/0.4VA), lower temperature operating limit (-20°C versus -30°C), and electrical life specification (10,000 versus 40,000 cycles). The ASE1E-2M-10-Z is rated for lower stress applications and shorter cycle life.

Q: Are both parts RoHS compliant?

A: Yes, both ES03MCBE and ASE1E-2M-10-Z are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the packaging format for both parts?

A: Both components are supplied in tray packaging suitable for automated assembly processes.

Q: Should I consider the actuator length difference between these parts?

A: The ES03MCBE has an actuator length of 3.07mm while the ASE1E-2M-10-Z measures 2.80mm. Verify that your enclosure or mechanical assembly accommodates the slightly shorter actuator of the substitute part.
