Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0031.8374 are identified based on strict electrical and mechanical parameter matching within the OGN-SMD series. All substitute parts maintain identical specifications for current rating (5A), voltage rating (250VAC), fuse type (cartridge glass), response time (fast blow), package dimensions (5mm x 20mm), mounting configuration (surface mount with holder), breaking capacity (50A), operating temperature range (-40°C to 85°C), and regulatory compliance (cURus, VDE approval, ROHS3 compliant).

The primary differentiating parameter among substitute parts is the Melting I²t value, which affects thermal response characteristics but does not alter the fundamental substitution eligibility when electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (0031.8324, 0031.8423, 0031.8473) are classified as Active product status and maintain full compliance with cURus and VDE approval agencies. Each part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Selection among these equivalent parts is based on availability and application-specific thermal response requirements. Parts 0031.8324 and 0031.8374 share identical Melting I²t values (102), while parts 0031.8423 and 0031.8473 feature lower Melting I²t values (33.8). All parts are electrically and mechanically interchangeable within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Are all listed parts direct substitutes for the SCHURTER 0031.8374?

A: Yes. Parts 0031.8324, 0031.8423, and 0031.8473 are parametric equivalents sharing identical current rating (5A), voltage rating (250VAC), fuse type (cartridge glass), response time (fast blow), package dimensions (5mm x 20mm), mounting configuration (surface mount with holder), breaking capacity (50A), and operating temperature range (-40°C to 85°C).

Q: What is the significance of the Melting I²t difference?

A: Melting I²t is a thermal characteristic that influences the fuse's response to thermal stress. Parts 0031.8374 and 0031.8324 have Melting I²t of 102, while parts 0031.8423 and 0031.8473 have Melting I²t of 33.8. This parameter does not affect substitution eligibility when electrical and mechanical specifications remain identical.

Q: Do all substitute parts require the same holder?

A: Yes. All parts in this equivalency group use the same 5mm x 20mm surface mount holder configuration. No holder modifications or additional components are required for substitution.

Q: Are all parts compliant with current regulatory standards?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and hold cURus and VDE approvals. All parts maintain Active product status.

Q: What is the difference in inventory availability?

A: Current inventory levels are: 0031.8374 (1312 pcs), 0031.8324 (1409 pcs), 0031.8423 (1154 pcs), and 0031.8473 (1108 pcs). Inventory status may affect procurement timelines but does not impact technical substitution criteria.
