Key Parameters

Substitute Part Grouping Explanation

The E-T-A 2-5700-IG1-K10-DD-20A qualifies as a direct substitute based on the following alignment of critical parameters:

• Current Rating: Both parts are rated for 20A, ensuring identical load protection characteristics
• Actuator Type: Both employ push-push actuation, maintaining identical user interface and reset functionality
• Mounting Type: Both are panel mount configurations, compatible with existing mechanical installations
• Number of Poles: Both are single-pole devices
• Breaker Type: Both are thermal breakers with identical trip mechanism classification

The substitute part exceeds the original specifications in voltage ratings (250V AC / 50V DC versus 240V AC / 28V DC), providing backward compatibility in applications operating at or below the original voltage levels. Both parts maintain ROHS3 compliance and EAR99 classification.

Parameter Comparison

Engineering Selection Recommendations

The E-T-A 2-5700-IG1-K10-DD-20A is suitable for direct replacement of the SCHURTER 4410.0103 in applications where the original part is no longer available. The substitute part maintains all critical functional parameters while offering improved voltage ratings. The active product status of the E-T-A component ensures ongoing availability and supply chain continuity. Both parts carry identical regulatory compliance certifications (ROHS3, REACH Unaffected, EAR99), supporting seamless integration into existing designs and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can the E-T-A 2-5700-IG1-K10-DD-20A replace the SCHURTER 4410.0103 in existing installations?

A: Yes. Both parts share identical current ratings (20A), actuator types (push-push), mounting configurations (panel mount), and pole counts (1). The substitute part's higher voltage ratings (250V AC / 50V DC) provide backward compatibility with applications operating at the original voltage levels (240V AC / 28V DC).

Q: What is the significance of the voltage rating difference?

A: The E-T-A substitute is rated for 250V AC and 50V DC, compared to the original 240V AC and 28V DC. This means the substitute part can operate safely in applications requiring the original voltage levels and in higher-voltage applications up to its rated limits. No derating is required for the original application parameters.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. Both share the same HTSUS code (8536.20.0020), indicating identical tariff classification for import/export purposes.

Q: What is the packaging difference?

A: The SCHURTER 4410.0103 is supplied with unspecified packaging, while the E-T-A 2-5700-IG1-K10-DD-20A is supplied in bulk packaging. Bulk packaging is standard for industrial component distribution and does not affect functional compatibility.

Q: Why is the SCHURTER part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The E-T-A substitute provides functional equivalence with active product status, ensuring long-term availability and supply chain reliability.
