SCHURTER 7010.2410 Equivalent & Substitute Parts

Part Overview

The SCHURTER 7010.2410 is a 1.5A 125VAC fast-blow glass cartridge fuse designed for applications requiring compact, non-standard cartridge form factors. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The non-standard 4.70mm x 16.00mm cartridge dimensions and specific electrical ratings necessitate careful evaluation of alternative sources that maintain functional equivalence while offering improved availability and extended product lifecycle support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7010.2410 is determined by the following critical parameters:

Current Rating Match: 1.5 A (exact match required)

Voltage Rating Compatibility: The main part operates at 125VAC. Substitute parts must support at minimum 125VAC operation. Higher voltage ratings (250VAC) provide enhanced safety margin and are acceptable for AC applications operating at or below 125VAC.

Fuse Characteristics: Fast-blow response time and glass cartridge construction must be maintained to preserve circuit protection behavior.

Breaking Capacity: Minimum 35A at rated voltage ensures equivalent fault current handling capability.

Melting I²t: The substitute part melting I²t value of 0.8 (compared to 0.63 for the main part) falls within acceptable tolerance for fast-blow cartridge fuses and does not compromise protection integrity.

Physical Form Factor: The main part uses a non-standard 4.70mm x 16.00mm cartridge. The substitute part (Littelfuse 022501.5HXP) uses the standardized 2AG form factor (5mm x 15mm), which is mechanically compatible with standard fuse holders and represents an upgrade path to industry-standard packaging.

Compliance & Certifications: Both parts maintain ROHS3 compliance and EAR99 classification. The substitute part carries multiple approval agencies (CE, CSA, PSE, UL), providing broader regulatory acceptance.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 022501.5HXP represents a direct functional substitute for the obsolete SCHURTER 7010.2410 based on matched current rating, fast-blow response, and breaking capacity specifications. The substitute part's higher AC voltage rating (250V vs. 125V) provides additional safety margin for 125VAC applications without compromising protection characteristics.

The transition from non-standard to 2AG standard form factor offers significant advantages: improved component availability, compatibility with widely-available fuse holders, and reduced long-term supply chain risk. The substitute part's active product status ensures continued manufacturing support and availability.

Both parts maintain equivalent RoHS3 compliance. The substitute part carries broader regulatory approvals (CE, CSA, PSE, UL) compared to the main part, supporting deployment across multiple geographic markets and application standards.

The extended operating temperature range (-55°C to 125°C) of the substitute part accommodates a wider range of environmental conditions than the main part (-40°C to 70°C), providing additional design flexibility for temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 022501.5HXP directly replace the SCHURTER 7010.2410 in existing designs?

A: Yes, provided the application uses a standard fuse holder compatible with the 2AG form factor (5mm x 15mm). The electrical characteristics—1.5A current rating, fast-blow response, and 35A breaking capacity—are functionally equivalent. If the original design uses a proprietary holder for the non-standard 4.70mm x 16.00mm cartridge, mechanical adaptation may be required.

Q: Why is the substitute part rated for 250VAC when the original is only 125VAC?

A: Higher voltage ratings indicate the fuse can safely interrupt circuits at elevated voltages. A 250VAC-rated fuse operates safely at 125VAC with additional safety margin. This does not affect protection performance at the lower voltage and is standard practice in component substitution.

Q: Does the substitute part's higher melting I²t value (0.8 vs. 0.63) affect circuit protection?

A: No. Both values fall within the fast-blow cartridge classification and are acceptable for equivalent protection. The I²t difference is negligible for typical circuit protection applications and does not compromise safety or performance.

Q: What is the advantage of the 2AG standard form factor?

A: The 2AG (5mm x 15mm) is an industry-standard cartridge size with widespread holder availability, lower cost, and guaranteed long-term supply. The original non-standard form factor presents supply chain risk and limits holder compatibility. Transitioning to 2AG improves system maintainability and reduces future obsolescence risk.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SCHURTER 7010.2410 and Littelfuse 022501.5HXP are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: Can the substitute part be used in DC applications?

A: The Littelfuse 022501.5HXP is rated for 125VDC operation, whereas the original part does not specify a DC rating. If the application requires DC circuit protection, the substitute part provides this capability as an added benefit.
