Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on electrical and mechanical compatibility:

Category 1: Littelfuse Glass Cartridge Fuses (Series 213, 218, 219XA) These parts share identical current rating (5A), voltage rating (250VAC), package dimensions (5x20mm), fuse type (glass cartridge), response time (slow blow), and operating temperature range (-55°C ~ 125°C). Substitution is determined by matching these core parameters. Variations in breaking capacity and melting I²t values reflect different series designs but do not prevent functional substitution in standard circuit protection applications.

Category 2: SCHURTER Ceramic Cartridge Fuse (0034.2523) This part matches current rating (5A), voltage rating (250VAC), package dimensions (5x20mm), and mounting type (requires holder). The primary difference is fuse material (ceramic vs. glass) and response time (medium blow vs. slow blow), which affects thermal characteristics and breaking capacity but maintains electrical compatibility for 5A 250VAC applications.

Engineering Selection Recommendations

Littelfuse Glass Cartridge Series (213, 218, 219XA, 618): All Littelfuse glass cartridge fuses listed maintain Active product status and ROHS3 compliance. Series 219XA (0219005.MXABP and 0219005.MXAP) and Series 218 parts provide higher breaking capacity (150A and 50A respectively) compared to Series 213 (50A). Series 218 and 618 exhibit lower melting I²t values (111 vs. 314 or 544), indicating faster thermal response. Selection among these parts depends on application-specific breaking capacity requirements and thermal response characteristics. All parts are certified to CCC, CE, CSA, PSE, SEMKO, UL, and VDE standards.

SCHURTER Ceramic Cartridge Fuse (0034.2523): This part provides ceramic construction with medium-blow response and significantly higher breaking capacity (1kA). The ceramic material and medium-blow characteristic differentiate it from glass slow-blow alternatives. This part is suitable for applications requiring higher fault current handling and different thermal response profiles. Operating temperature range is -40°C ~ 85°C, which is narrower than Littelfuse glass alternatives.

Frequently Asked Questions (FAQ)

Q: Can I substitute a Littelfuse Series 218 fuse for the 0219005.MXABP? A: Yes. Both parts share identical current rating (5A), voltage rating (250VAC), package dimensions (5x20mm), fuse type (glass), response time (slow blow), and operating temperature range (-55°C ~ 125°C). The primary difference is breaking capacity: Series 219XA provides 150A while Series 218 provides 50A. For applications not requiring the higher breaking capacity of Series 219XA, Series 218 parts are functionally equivalent.

Q: What is the difference between glass and ceramic cartridge fuses? A: Glass and ceramic fuses differ in material construction and thermal characteristics. Glass fuses (Littelfuse series) provide slow-blow response with melting I²t values ranging from 111 to 544. The ceramic fuse (SCHURTER 0034.2523) provides medium-blow response with melting I²t of 52.5 and significantly higher breaking capacity (1kA vs. 50-150A). Material selection depends on application thermal requirements and fault current handling specifications.

Q: Are all substitute parts ROHS3 compliant? A: All Littelfuse glass cartridge fuses listed (Series 213, 218, 219XA, 618) are ROHS3 compliant. The SCHURTER ceramic fuse (0034.2523) is also ROHS3 compliant. All parts are REACH Unaffected.

Q: What certifications apply to these fuses? A: Littelfuse glass cartridge fuses carry certifications including CCC, CE, CSA, PSE, SEMKO, UL, and VDE (with variations by series). The SCHURTER ceramic fuse carries no listed approval agencies in the provided data. Verify specific certification requirements for your application before selection.

Q: Can I use the SCHURTER 0034.2523 as a direct replacement? A: The SCHURTER 0034.2523 matches current rating (5A), voltage rating (250VAC), and package dimensions (5x20mm). However, it differs in fuse material (ceramic vs. glass), response time (medium blow vs. slow blow), and operating temperature range (-40°C ~ 85°C vs. -55°C ~ 125°C). Use this part only if your application specifications permit ceramic construction and medium-blow response characteristics.

Q: Which substitute part has the highest inventory availability? A: The Littelfuse 0218005.MXP (Series 218) has the highest inventory at 42,700 pieces, followed by 0618005.MXP (Series 618) at 34,200 pieces.
