SCHURTER 0031.8355 Glass Fuse Cartridge 63mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The SCHURTER 0031.8355 is a 63 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 element is rated for 5mm x 20mm form factor with a breaking capacity of 35A at rated voltage. The part is currently active in production with full compliance to RoHS3, VDE, and cURus standards. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the OGN-SMD product line.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0031.8355 are qualified based on strict electrical and mechanical parameter equivalence within the OGN-SMD series. All substitute parts maintain identical specifications for current rating (63 mA), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast blow), package dimensions (5mm x 20mm), mounting configuration (requires holder, surface mount), breaking capacity (35A), operating temperature range (-40°C to 85°C), and regulatory compliance (cURus, VDE, RoHS3). Substitution is valid when these core parameters are matched. Variations in melting I²t values (0.0401 versus 0.037) represent minor manufacturing tolerance differences within the same product family and do not affect substitution eligibility for the specified electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

All four parts (0031.8355, 0031.8305, 0031.8501, 0031.8551) are active production components within the SCHURTER OGN-SMD series and carry identical regulatory certifications (cURus, VDE) with full RoHS3 compliance. Selection among these equivalents may be based on inventory availability and lead time considerations. The melting I²t parameter variation (0.0401 versus 0.037) reflects standard manufacturing tolerance within the OGN-SMD product family and does not impact functional equivalence for the specified 63 mA, 250 V AC/DC application. All parts are packaged in Tape & Reel format suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 0031.8305, 0031.8501, and 0031.8551 be used interchangeably with 0031.8355?

A: Yes. All four parts maintain identical electrical ratings (63 mA, 250 V AC), fuse type (cartridge glass), response time (fast blow), mechanical package (5mm x 20mm with holder), mounting configuration (surface mount requiring holder), breaking capacity (35A), and regulatory compliance (cURus, VDE, RoHS3). They are direct equivalents within the OGN-SMD series.

Q: What does the difference in melting I²t values (0.0401 versus 0.037) indicate?

A: The melting I²t parameter represents the thermal energy required to melt the fuse element. The variation between 0.0401 and 0.037 reflects standard manufacturing tolerance within the OGN-SMD product line and does not affect substitution eligibility or functional performance for the specified 63 mA, 250 V AC/DC rating.

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

A: Yes. All four parts are supplied in Tape & Reel (TR) packaging, suitable for automated surface mount assembly processes.

Q: Do all substitute parts meet the same regulatory standards?

A: Yes. All parts carry identical approvals: cURus and VDE certification, with full RoHS3 compliance and REACH unaffected status.

Q: What is the operating temperature range for these fuse cartridges?

A: All parts operate within the range of -40°C to 85°C, suitable for industrial and commercial applications.
