Key Parameters

Substitute Part Grouping Explanation

The ESS30-S003-DC24V-6A qualifies as a manufacturer-recommended substitute based on the following critical parameters:

Matching Parameters:

• Breaker Type: Solid State (identical technology)
• Current Rating: 6A (identical amperage)
• Voltage Rating - DC: 24V (identical voltage specification)
• Number of Poles: 1 (identical pole configuration)
• Mounting Type: Holder (identical mechanical interface)
• Approval Agency: IEC 60934, UL1077 (identical certifications)
• RoHS Status: ROHS3 Compliant (identical compliance)

Differing Parameters:

• Series: ESS30-S (upgraded series from ESS20)
• Actuator Type: Pushbutton (differs from push-push)
• Voltage Rating - DC: 30V (higher rating than 24V requirement)
• Illumination: Green, Orange, Red (expanded from green, orange)
• Product Status: Active (versus obsolete)

The substitute maintains all critical electrical and mechanical parameters required for functional equivalence while offering enhanced voltage margin and active product status.

Parameter Comparison

Engineering Selection Recommendations

The ESS30-S003-DC24V-6A is the manufacturer-designated substitute for the obsolete ESS20-003-DC24V-6A. Both components maintain identical current and voltage specifications for 24V DC operation at 6A capacity. The substitute operates at a higher voltage rating (30V) while maintaining the same 24V DC specification, providing additional design margin.

Both parts carry identical regulatory approvals (IEC 60934, UL1077) and ROHS3 compliance status, ensuring equivalent safety and environmental standards. The primary operational difference is the actuator interface: the substitute uses a pushbutton actuator instead of push-push control. The substitute's active product status ensures continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the ESS30-S003-DC24V-6A directly replace the ESS20-003-DC24V-6A?

A: Yes. Both components share identical current rating (6A), DC voltage specification (24V), pole configuration (1), mounting type (holder), and regulatory approvals. The substitute is the manufacturer-recommended equivalent.

Q: What is the significance of the higher 30V DC rating on the substitute?

A: The ESS30-S003-DC24V-6A is rated for 30V DC operation, which exceeds the 24V requirement. This provides additional voltage margin and does not affect compatibility in 24V DC circuits.

Q: Does the actuator type change affect circuit operation?

A: The actuator type differs between models (push-push versus pushbutton). This affects the mechanical interface and control method but does not alter the electrical switching function or circuit protection characteristics.

Q: Are the regulatory certifications equivalent?

A: Yes. Both the ESS20-003-DC24V-6A and ESS30-S003-DC24V-6A carry identical approvals under IEC 60934 and UL1077, with matching ROHS3 compliance status.

Q: Why is the original part listed as obsolete?

A: The ESS20 series has been superseded by the ESS30-S series. The substitute represents the current active product line from E-T-A for this application category.

Q: Are there packaging differences between these parts?

A: The original part is listed with standard packaging, while the substitute is supplied in bulk packaging. Both are suitable for component selection and integration.
