SCHURTER 0031.8307 Glass Fuse Cartridge 100mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The SCHURTER 0031.8307 is a 100 mA, 250 V AC/DC glass fuse cartridge in the OGN-SMD series, designed for surface mount applications requiring a holder. This fast-blow fuse cartridge measures 5mm x 20mm and is actively manufactured. Substitute parts are identified when component availability is limited, inventory constraints exist, or supply chain optimization is required while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0031.8307 are qualified based on strict electrical and mechanical parameter matching:

Qualifying Parameters for Substitution:

• Current Rating: 100 mA (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)
• Breaking Capacity @ Rated Voltage: 35A (exact match required)
• Mounting Type: Requires Holder, Surface Mount (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)

All three substitute parts (0031.8357, 0031.8503, 0031.8553) meet these criteria and are direct parametric equivalents from SCHURTER Inc. within the OGN-SMD series.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (0031.8357, 0031.8503, 0031.8553) are direct parametric equivalents to the SCHURTER 0031.8307 and are suitable for interchangeable use in applications requiring a 100 mA, 250 V AC/DC fast-blow glass fuse cartridge in 5mm x 20mm form factor.

Selection Basis:

• All parts maintain identical electrical ratings and mechanical dimensions
• All parts carry active product status from SCHURTER Inc.
• All parts comply with cURus and VDE approval requirements
• All parts meet ROHS3 compliance standards
• All parts are available in Tape & Reel packaging for surface mount assembly

The primary distinction among substitute parts is the Melting I²t value: parts 0031.8307 and 0031.8357 specify 0.107, while parts 0031.8503 and 0031.8553 specify 0.14. This parameter difference does not affect substitution eligibility within the OGN-SMD series, as all parts maintain the same current rating, voltage rating, and response time characteristics.

Frequently Asked Questions (FAQ)

Q: Can 0031.8357, 0031.8503, and 0031.8553 be used interchangeably with 0031.8307?

A: Yes. All three parts are parametric equivalents with identical current ratings (100 mA), voltage ratings (250 V AC), fuse type (cartridge, glass), response time (fast blow), package dimensions (5mm x 20mm w/Holder), breaking capacity (35A), mounting type (requires holder, surface mount), operating temperature range (-40°C ~ 85°C), and regulatory approvals (cURus, VDE). They are direct substitutes within the SCHURTER OGN-SMD series.

Q: What is the difference between these substitute parts?

A: The primary difference is the Melting I²t value. Parts 0031.8307 and 0031.8357 have a Melting I²t of 0.107, while parts 0031.8503 and 0031.8553 have a Melting I²t of 0.14. All other electrical and mechanical parameters remain identical across all four parts.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts, including the main part 0031.8307 and all three substitutes (0031.8357, 0031.8503, 0031.8553), are ROHS3 compliant.

Q: Do these fuses require a holder for installation?

A: Yes. All parts in this group are specified as "Requires Holder, Surface Mount." The 5mm x 20mm w/Holder package designation indicates that a compatible fuse holder is required for proper installation and operation.

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

A: Yes. All parts are rated for 250 V AC/DC operation, making them suitable for both alternating and direct current applications within the specified voltage range.

Q: What regulatory approvals do these fuses carry?

A: All parts carry approvals from cURus (Canadian and U.S. regulatory bodies) and VDE (Verband der Elektrotechnik, Elektronik und Informationstechnik), ensuring compliance with North American and European safety standards.
