Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0031.8362 are identified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

• Current Rating: 315 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)
• Mounting Type: Requires Holder, Surface Mount (exact match required)
• Breaking Capacity @ Rated Voltage: 35A (exact match required)
• Approval Agencies: cURus, VDE (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All substitute parts listed below meet these criteria and are manufactured by SCHURTER Inc. within the OGN-SMD series.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—0031.8312, 0031.8508, and 0031.8558—are active products manufactured by SCHURTER Inc. and carry identical electrical ratings, mechanical dimensions, and approval certifications (cURus, VDE) as the main part 0031.8362. Each substitute maintains ROHS3 compliance and operates within the same temperature range.

The primary distinction among these parts is the Melting I²t value. The 0031.8362 and 0031.8312 share a Melting I²t of 0.544, while 0031.8508 and 0031.8558 have a Melting I²t of 4.17. This parameter affects the thermal energy dissipation characteristics of the fuse but does not alter the fundamental substitution eligibility based on the provided electrical and mechanical specifications.

Selection between these parts should be based on circuit design requirements and thermal performance needs specific to the application.

Frequently Asked Questions (FAQ)

Q: Can 0031.8312, 0031.8508, and 0031.8558 be used interchangeably with 0031.8362?

A: Yes, all three parts meet the core electrical and mechanical substitution criteria: 315 mA current rating, 250 V AC voltage rating, fast-blow response, 5mm x 20mm package with holder, 35A breaking capacity, and identical approval certifications. All are active products with ROHS3 compliance.

Q: What is the significance of the different Melting I²t values?

A: The Melting I²t parameter characterizes the thermal energy required to melt the fuse element. The 0031.8362 and 0031.8312 have a Melting I²t of 0.544, while 0031.8508 and 0031.8558 have a Melting I²t of 4.17. This difference affects thermal response characteristics but does not change the fuse's rated current or voltage specifications.

Q: Are all substitute parts available in the same packaging format?

A: Yes, all parts are supplied in Tape & Reel (TR) packaging, consistent with the main part 0031.8362.

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

A: Yes, all substitute parts carry cURus and VDE approvals and are ROHS3 compliant, matching the main part's compliance profile.

Q: What is the operating temperature range for these fuses?

A: All parts, including the main part and substitutes, operate within -40°C to 85°C.
