SCHURTER 0031.8419 Glass Fuse Cartridge 2A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The SCHURTER 0031.8419 is a 2 A 250 V AC/DC glass fuse cartridge in 5mm x 20mm form factor, designed for surface mount applications requiring a holder. This fast-blow fuse is part of the OGN-SMD series and maintains active product status with full regulatory compliance. Equivalent and substitute parts within this series share identical electrical ratings and mechanical specifications, differing primarily in melting I²t characteristics, which determine thermal response behavior under fault conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the SCHURTER OGN-SMD 2A 250VAC 5x20mm series is determined by the following critical parameters:

• Current Rating: 2 A (all equivalents match)
• Voltage Rating: 250 V AC (all equivalents match)
• Fuse Type: Cartridge, Glass (all equivalents match)
• Package / Case: 5mm x 20mm w/Holder (all equivalents match)
• Mounting Type: Requires Holder, Surface Mount (all equivalents match)
• Response Time: Fast Blow (all equivalents match)
• Breaking Capacity: 35 A (all equivalents match)
• Operating Temperature: -40°C ~ 85°C (all equivalents match)
• Approval Agencies: cURus, VDE (all equivalents match)

The melting I²t parameter varies among equivalent parts (5.28, 16, or 124), reflecting different thermal response characteristics. All substitute parts maintain identical electrical and mechanical compatibility with the main part number 0031.8419.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and carry identical regulatory certifications (cURus, VDE). All parts are ROHS3 compliant and REACH unaffected. Selection among equivalent part numbers should be based on application-specific thermal response requirements, as determined by the melting I²t parameter. The electrical and mechanical compatibility is guaranteed across all listed part numbers within the OGN-SMD series.

Frequently Asked Questions (FAQ)

Q: Can part 0031.8419 be directly replaced with 0031.8469? A: Yes. Both parts share identical current rating (2 A), voltage rating (250 V AC), fuse type (cartridge, glass), package dimensions (5mm x 20mm w/Holder), mounting type (requires holder, surface mount), response time (fast blow), breaking capacity (35 A), and operating temperature range (-40°C ~ 85°C). Both carry cURus and VDE approvals.

Q: What is the difference between parts with melting I²t values of 5.28, 16, and 124? A: The melting I²t parameter defines the thermal energy required to melt the fuse element. This affects the fuse's response time under specific fault current conditions. All parts maintain the same fast-blow response classification and identical electrical ratings.

Q: Are all substitute parts available in the same packaging format? A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging with identical 5mm x 20mm form factor and holder configuration.

Q: Do all substitute parts meet the same regulatory requirements? A: Yes. All parts carry cURus and VDE approvals, are ROHS3 compliant, and are REACH unaffected.

Q: Can I use part 0031.8516 or 0031.8566 as a direct replacement for 0031.8419? A: Yes, from an electrical and mechanical standpoint. Both parts meet all specified electrical parameters and mechanical requirements. The difference lies in the melting I²t value (124 versus 5.28), which affects thermal response characteristics.
