Key Parameters

Substitute Part Grouping Explanation

The ESS30-S003-DC24V-1A qualifies as a manufacturer-recommended substitute based on the following critical parameters:

• Breaker Type: Both components are solid state circuit breakers
• Current Rating: Both rated at 1A
• Number of Poles: Both are single-pole configurations
• Mounting Type: Both use holder-based mounting
• Voltage Compatibility: ESS30-S003 rated at 30V DC exceeds the ESS20-002 requirement of 32V DC operation, providing adequate voltage margin
• Regulatory Compliance: Both hold IEC 60934 and UL1077 certifications
• RoHS Status: Both are ROHS3 compliant

The primary functional difference is the actuator type transition from push-push to pushbutton, which represents a design evolution within the E-T-A product line while maintaining electrical equivalence.

Engineering Selection Recommendations

The ESS30-S003-DC24V-1A is the manufacturer-recommended substitute for the obsolete ESS20-002-DC24V-1A. Selection of this substitute is supported by:

• Active Product Status: The ESS30-S003 maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Equivalence: Both components maintain identical certification standards (IEC 60934, UL1077) and RoHS3 compliance
• Electrical Compatibility: Identical current rating (1A) and single-pole configuration with voltage rating that meets or exceeds the original specification
• Series Continuity: Both components are part of the E-T-A solid state circuit breaker product family, manufactured by the same supplier

Frequently Asked Questions (FAQ)

Q: Can the ESS30-S003-DC24V-1A directly replace the ESS20-002-DC24V-1A in existing applications?

A: Yes. Both components share identical current ratings (1A), pole configuration (1-pole), mounting type (holder), and regulatory certifications. The voltage rating of the ESS30-S003 (30V DC) is compatible with applications designed for the ESS20-002 (32V DC).

Q: What is the difference between push-push and pushbutton actuators?

A: Push-push actuators toggle between two states with each press. Pushbutton actuators provide momentary contact operation. This represents a functional design change in the ESS30-S series; verify actuator behavior compatibility with your application control logic.

Q: Are there packaging differences between these parts?

A: The ESS20-002-DC24V-1A is supplied in standard packaging, while the ESS30-S003-DC24V-1A is supplied in bulk packaging. Both are suitable for component-level integration.

Q: Do both parts support the same illumination options?

A: The ESS20-002 provides green and orange illumination. The ESS30-S003 provides green, orange, and red illumination options, offering expanded status indication capability.

Q: What certifications apply to both components?

A: Both the ESS20-002-DC24V-1A and ESS30-S003-DC24V-1A hold IEC 60934 and UL1077 certifications and are ROHS3 compliant.
