Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0031.8319 are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical current rating (1.6 A), voltage rating (250 V AC), response time (Fast Blow), and breaking capacity (35 A) as the main part.

Mechanical Compatibility: All substitute parts share the same package dimensions (5mm x 20mm w/Holder) and mounting configuration (Requires Holder, Surface Mount), ensuring direct mechanical interchangeability.

Series Consistency: All parts belong to the OGN-SMD series and maintain the same fuse type (Cartridge, Glass).

Regulatory Compliance: All substitute parts carry identical approval agencies (cURus, VDE), ROHS3 compliance status, and operating temperature range (-40°C ~ 85°C).

Variable Parameter: The Melting I²t value differs among substitute parts (10.5, 2.94, or 87), representing different thermal response characteristics within the same electrical and mechanical envelope. This parameter determines the specific thermal behavior of the fuse under overload conditions.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and carry identical regulatory approvals (cURus, VDE) with ROHS3 compliance. Selection among these equivalents should be based on the specific thermal response requirement of the application, as determined by the Melting I²t parameter.

Parts 0031.8369 and 0031.8319 share identical Melting I²t values (10.5) and represent direct parametric equivalents. Parts 0031.8418 and 0031.8468 feature lower Melting I²t values (2.94), indicating faster thermal response. Parts 0031.8515 and 0031.8565 feature higher Melting I²t values (87), indicating slower thermal response.

All parts maintain the same mechanical footprint, electrical ratings, and regulatory compliance framework, ensuring compatibility within the OGN-SMD series for 1.6 A 250 V AC/DC applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute 0031.8319 with any of the listed equivalent parts?

A: Yes. All listed parts are parametric equivalents sharing identical current rating (1.6 A), voltage rating (250 V AC), package dimensions (5mm x 20mm w/Holder), mounting type (Requires Holder, Surface Mount), breaking capacity (35 A), and regulatory approvals (cURus, VDE). The Melting I²t parameter differs, affecting thermal response characteristics.

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

A: Melting I²t determines the thermal energy required to melt the fuse element. Lower values (2.94) indicate faster thermal response to overload conditions. Higher values (87) indicate slower thermal response. The original part 0031.8319 has a Melting I²t of 10.5. Selection should match the thermal protection requirements of the specific application circuit.

Q: Are all substitute parts surface mount compatible?

A: Yes. All parts require a holder for surface mount installation and share identical 5mm x 20mm package dimensions with the main part.

Q: Do all substitute parts carry the same regulatory approvals?

A: Yes. All parts hold cURus and VDE approvals, maintain ROHS3 compliance, and operate within the same temperature range (-40°C ~ 85°C).

Q: What is the inventory status of substitute parts?

A: All substitute parts maintain active product status with current inventory availability ranging from 1249 to 1537 pieces in Tape & Reel packaging.
