Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (5 A), voltage rating (250 V AC), fuse type (cartridge glass), response time (slow blow), physical dimensions (5mm x 20mm), and mounting requirement (holder-based). Substitute parts are grouped into two categories based on electrical characteristics:

Category 1: Littelfuse Series 213 and 218 (Melting I²t: 111-314) Parts 0213005.MXBP, 0213005.MXP, 0213005.TXP, 0218005.HXP, 0218005.MXP, and 0218005.VXP share identical current, voltage, and dimensional specifications with breaking capacity of 50A at rated voltage. These parts differ in melting I²t values and approval agency certifications but maintain functional equivalence for standard circuit protection.

Category 2: Littelfuse Series 219XA (Melting I²t: 544, Breaking Capacity: 150A) Parts 0219005.MXABP and 0219005.MXAP feature enhanced breaking capacity (150A) and higher melting I²t (544) compared to the main part (50A, I²t 111). These provide upgraded performance characteristics while maintaining identical current, voltage, and dimensional specifications.

Category 3: Littelfuse Series 618 (Melting I²t: 111, Breaking Capacity: 50A) Part 0618005.MXP matches the main part's electrical and thermal characteristics with identical breaking capacity and melting I²t, differing only in series designation and approval agency coverage.

Category 4: SCHURTER FST 5x20 Series (Melting I²t: 102, Breaking Capacity: 50A) Part 0034.3124 from SCHURTER Inc. provides cross-manufacturer equivalence with matching current, voltage, dimensions, and response time, with melting I²t of 102 (comparable to Littelfuse 218 series at 111).

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and environmental regulatory adherence. Selection between Littelfuse Series 218 and 213 variants depends on approval agency requirements: Series 218 parts (0218005.HXP, 0218005.MXP, 0218005.VXP) carry UL and K-MARK certifications, while Series 213 parts (0213005.MXBP, 0213005.MXP, 0213005.TXP) include BSI and UR certifications. Series 219XA parts (0219005.MXABP, 0219005.MXAP) are suitable for applications requiring higher breaking capacity (150A) and thermal energy handling (I²t 544). The SCHURTER 0034.3124 provides cross-manufacturer equivalence with comparable melting I²t (102) and identical electrical ratings, suitable for applications where multi-source supply is required.

Frequently Asked Questions (FAQ)

Q: Can Series 213 parts replace Series 218 parts directly? A: Yes. Both series share identical current (5 A), voltage (250 V AC), response time (slow blow), and physical dimensions (5x20mm). Differences in melting I²t (213: 314 vs. 218: 111) and approval certifications do not affect functional interchangeability in standard circuit protection applications. Selection should be based on specific approval agency requirements for your application.

Q: What is the difference between standard Series 218 and Series 219XA? A: Series 219XA provides enhanced breaking capacity (150A vs. 50A) and higher melting I²t (544 vs. 111). Both maintain identical current, voltage, and dimensional specifications. Series 219XA is suitable for applications requiring higher fault current handling capability.

Q: Is the SCHURTER 0034.3124 fully compatible with Littelfuse parts? A: Yes. The SCHURTER FST 5x20 series part 0034.3124 matches all critical electrical parameters: 5 A current rating, 250 V AC voltage rating, slow-blow response, and 5x20mm physical dimensions. The melting I²t of 102 is comparable to Littelfuse Series 218 (111). Compatibility is confirmed for standard circuit protection applications.

Q: Does holder type affect substitution eligibility? A: No. All listed parts require holder mounting and are designed for standard 5x20mm fuse holders. Physical dimensions and holder interface specifications are identical across all substitute parts.

Q: What approval agencies are common across all substitute parts? A: CCC, CE, CSA, PSE, SEMKO, and VDE certifications are present across the majority of listed parts. Specific approval agency coverage varies by part number; verify certifications against your application requirements before final selection.
