Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (800 mA), voltage rating (250 V AC), package dimensions (5mm x 20mm), fuse type (cartridge glass), response time (slow blow), and mounting requirement (requires holder). Parts are grouped into three categories:

Parametric Equivalents (Littelfuse Series 218, 219XA, 239): These parts share identical electrical ratings, dimensions, and response characteristics with the main part. Variations in melting I²t, DC cold resistance, and breaking capacity are within acceptable ranges for the same application class. Approval agency certifications differ but maintain compliance standards.

Manufacturer Recommended Equivalents (SCHURTER, Bel Fuse, Eaton): These parts from alternative manufacturers meet the same electrical and mechanical specifications. Operating temperature ranges and approval agencies may vary; however, all maintain the core functional parameters required for direct substitution.

Critical Substitution Parameters: Current rating, voltage rating, package dimensions, fuse type, response time, and mounting configuration must remain constant across all substitutes.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and are ROHS3 compliant. Selection among Littelfuse Series 218, 219XA, and 239 variants depends on application-specific requirements for melting I²t and DC cold resistance characteristics, which influence thermal response and circuit behavior.

For applications requiring extended temperature operation across the full -55°C to 125°C range, Littelfuse 0218.800MXP, 0218.800HXP, 0218.800TXP, and Bel Fuse 5ST 800-R maintain this specification. The SCHURTER 0034.3774 operates within -40°C to 85°C and is suitable for applications within this narrower range.

Approval agency certifications vary across manufacturers. Littelfuse parts carry certifications including BSI, CCC, CE, CSA, SEMKO, UR, and VDE. SCHURTER 0034.3774 holds cULus certification. Bel Fuse 5ST 800-R carries CCC, CE, CSA, cURus, IMQ, SEMKO, and VDE certifications. Eaton parts carry cULus and IMQ (GDC variant) or CSA and UL (GMD variant) certifications. Selection should align with regional compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can 0218.800MXP directly replace 0213.800MXP?

A: Yes. Both parts share identical current rating (800 mA), voltage rating (250 V AC), package dimensions (5x20mm), fuse type (cartridge glass), response time (slow blow), and mounting requirement (requires holder). Differences in melting I²t (3.37 vs. 9.42) and DC cold resistance (0.0813 vs. 0.1635 Ω) reflect different thermal response characteristics within the same application class.

Q: What is the difference between Littelfuse Series 218 and Series 239?

A: Series 218 and Series 239 maintain identical electrical and mechanical specifications for the 800 mA, 250 V rating. Primary differences include melting I²t values (3.37 for Series 218 vs. 7.565 for Series 239) and DC cold resistance (0.0813 Ω vs. 0.4155 Ω), which affect thermal response behavior. Approval agency certifications also differ between series.

Q: Is 0219.800MXAP a suitable substitute?

A: 0219.800MXAP matches all core electrical and mechanical parameters. The primary distinction is breaking capacity at rated voltage (150A vs. 35A for the main part), indicating higher fault current handling capability. This part is suitable for applications requiring enhanced breaking capacity while maintaining identical current and voltage ratings.

Q: Can I use SCHURTER 0034.3774 in applications requiring -55°C operation?

A: No. SCHURTER 0034.3774 operates within -40°C to 85°C, which does not cover the full -55°C to 125°C range of the main part. Use this substitute only in applications where the operating temperature remains within -40°C to 85°C.

Q: What are the approval agency differences between manufacturers?

A: Littelfuse parts carry BSI, CCC, CE, CSA, SEMKO, UR, and VDE certifications. SCHURTER holds cULus certification. Bel Fuse 5ST 800-R carries CCC, CE, CSA, cURus, IMQ, SEMKO, and VDE certifications. Eaton GDC variant carries cULus and IMQ; GMD variant carries CSA and UL. Select based on regional compliance requirements.

Q: Are all substitutes ROHS3 compliant?

A: All listed Littelfuse, SCHURTER, and Bel Fuse parts are ROHS3 compliant. Eaton BK/GDC-800MA is RoHS compliant; BK/GMD-800-R is ROHS3 compliant.
