SCHURTER 0031.8326 Glass Fuse Cartridge 8A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The SCHURTER 0031.8326 is an 8A 250VAC glass fuse cartridge designed for surface mount applications requiring a holder. This fast-blow fuse element operates within the OGN-SMD series and maintains active product status with full regulatory compliance. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same fuse category, voltage rating, current rating, and physical package dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0031.8326 are qualified based on strict equivalence across the following critical parameters:

• Current Rating: 8 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm w/Holder (exact match required)
• Mounting Type: Requires Holder, Surface Mount (exact match required)
• Breaking Capacity @ Rated Voltage: 80A (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Approval Agencies: cURus, VDE (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute parts 0031.8425 and 0031.8475 meet all these criteria. Variation in Melting I²t values (275 for 0031.8326 versus 93.4 for both substitutes) does not disqualify substitution when all other electrical and mechanical parameters remain equivalent within the OGN-SMD series classification.

Parameter Comparison

Engineering Selection Recommendations

All three fuse cartridges—0031.8326, 0031.8425, and 0031.8475—maintain active product status and carry identical regulatory certifications (cURus, VDE). Each component is ROHS3 compliant and operates within the same temperature range. Selection between these parts should be based on inventory availability and application-specific requirements related to melting I²t characteristics, which define the thermal energy dissipation profile during fault conditions. The substitute parts are electrically and mechanically interchangeable within circuits designed for the OGN-SMD 8A 250VAC fast-blow fuse category.

Frequently Asked Questions (FAQ)

Q: Can 0031.8425 or 0031.8475 be used as direct replacements for 0031.8326?

A: Yes. Both substitute parts maintain identical current rating (8A), voltage rating (250VAC), fuse type (cartridge, glass), response time (fast blow), package dimensions (5mm x 20mm), mounting configuration (requires holder, surface mount), breaking capacity (80A), operating temperature range (-40°C to 85°C), and regulatory approvals (cURus, VDE). All three parts belong to the OGN-SMD series.

Q: What is the difference between these three fuse cartridges?

A: The primary difference is the Melting I²t value. The 0031.8326 has a Melting I²t of 275, while both 0031.8425 and 0031.8475 have a Melting I²t of 93.4. This parameter defines the thermal energy threshold at which the fuse element melts. All other electrical and mechanical specifications are identical.

Q: Are these fuses suitable for both AC and DC applications?

A: The voltage rating specified is 250V AC. The detailed description indicates AC DC capability, but component selection should be confirmed against the specific application voltage and current profile.

Q: Do these fuse cartridges require a holder for installation?

A: Yes. All three parts are classified as "Requires Holder, Surface Mount." The 5mm x 20mm package dimensions include the holder configuration. Installation requires a compatible surface mount fuse holder designed for this package specification.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 0031.8326, 0031.8425, and 0031.8475 are all ROHS3 compliant and carry VDE and cURus approvals.
