SCHURTER 2020.0002 Fuse Cartridge 630mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The SCHURTER 2020.0002 is a slow-blow fuse cartridge rated at 630mA, 250VAC, housed in a 5x20mm form factor. This component is classified as obsolete and requires a dedicated fuse holder for installation. The part is designed for telecom applications and carries multiple international approvals including CSA, UR, and VDE certification. Due to its obsolete status, identifying functionally equivalent substitute components is essential for system maintenance, repair, and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 2020.0002 is determined by the following critical parameters:

• Current Rating: Must be 630mA
• Voltage Rating - AC: Must be 250VAC or higher
• Package / Case: Must be 5mm x 20mm
• Fuse Type: Must be Cartridge
• Response Time: Must be Slow Blow
• Mounting Type: Must require holder compatibility

The substitute part SCHURTER 0001.2502 meets all these criteria. It maintains the same current rating, AC voltage specification, physical dimensions, cartridge form factor, and slow-blow response characteristic. The substitute additionally provides 300VDC rating capability, which does not conflict with the primary AC application requirement. Both parts carry international safety certifications and maintain ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0001.2502 is the direct substitute for the obsolete SCHURTER 2020.0002. Both components share identical electrical specifications for AC operation at 630mA and 250VAC, maintain the same 5x20mm physical form factor, and are compatible with standard fuse holders designed for this package size.

The substitute part offers an extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), providing greater thermal margin in applications subject to temperature extremes. The ceramic construction of the substitute part is a standard material upgrade within the SCHURTER product line and does not introduce compatibility issues.

Both parts carry international safety certifications and maintain ROHS3 compliance. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0001.2502 be used as a direct replacement for the 2020.0002?

A: Yes. Both parts are rated at 630mA, 250VAC, use the same 5mm x 20mm cartridge form factor, and require identical holder compatibility. The electrical and mechanical specifications are equivalent for AC applications.

Q: What is the difference between the main part and the substitute?

A: The primary differences are product status and material construction. The 2020.0002 is obsolete; the 0001.2502 is active production. The substitute features ceramic construction and an extended operating temperature range (-55°C to 125°C versus -40°C to 85°C). The substitute also provides 300VDC rating capability in addition to the 250VAC specification.

Q: Are there any compatibility concerns with fuse holders?

A: No. Both parts use the standard 5mm x 20mm cartridge package and are compatible with any fuse holder designed for this form factor.

Q: Does the ceramic construction of the substitute affect performance?

A: No. Ceramic fuse construction is a standard material specification within the SCHURTER product line and maintains the same slow-blow response time and current rating as the main part.

Q: What certifications apply to the substitute part?

A: The SCHURTER 0001.2502 carries cURus and VDE approvals and is ROHS3 compliant. These certifications meet the regulatory requirements of the original part.

Q: Is the extended temperature range of the substitute a concern?

A: No. The extended operating range (-55°C to 125°C) provides additional thermal margin and does not introduce any compatibility or performance issues for applications within the original part's temperature specification (-40°C to 85°C).
