Littelfuse 0215008.TXP Ceramic Fuse 8A 250VAC 5x20mm - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0215008.TXP is an 8A 250VAC ceramic cartridge fuse in 5x20mm form factor, designed for slow-blow protection in AC/DC circuits. This Active product requires a fuse holder for installation. Substitute parts become necessary due to inventory constraints, supply chain disruptions, or specific application requirements such as DC voltage rating or breaking capacity specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (8A), AC voltage rating (250V), fuse type (cartridge ceramic), response time (slow blow), and physical package (5x20mm). All substitute parts listed maintain these core electrical and mechanical specifications.

Littelfuse parts (0215008.HXP, 0215008.MXP) are parametric equivalents with identical electrical characteristics and certifications. SCHURTER parts (0001.2513, 0001.2713.11) provide direct substitution with additional DC voltage rating (150V DC) and alternative breaking capacity specifications. OptiFuse parts (TCC-8A, TCD-8A) are parametric equivalents with variations in breaking capacity and melting I²t values.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and are RoHS3 compliant. Selection between Littelfuse variants (0215008.HXP, 0215008.MXP) is based on inventory availability and identical electrical performance. SCHURTER parts (0001.2513, 0001.2713.11) are suitable for applications requiring DC voltage capability (150V DC) and provide higher melting I²t (268 vs. 209.88). OptiFuse TCC-8A and TCD-8A are suitable where OptiFuse certifications (cULus, UL 248, IEC 60127) align with application requirements. Breaking capacity differences must be evaluated against circuit protection requirements: Littelfuse and SCHURTER parts provide 1.5kA, while OptiFuse TCC-8A provides 200A breaking capacity.

Frequently Asked Questions (FAQ)

Q: Can 0215008.HXP and 0215008.MXP be used interchangeably with 0215008.TXP? A: Yes. All three Littelfuse parts are parametric equivalents with identical current rating (8A), voltage rating (250VAC), response time (slow blow), package (5x20mm), breaking capacity (1.5kA), and melting I²t (209.88). They differ only in packaging designation and inventory availability.

Q: What is the difference between Littelfuse and SCHURTER substitute parts? A: SCHURTER parts (0001.2513, 0001.2713.11) add DC voltage rating (150V DC) and higher melting I²t (268). Littelfuse parts maintain the original AC-only specification with lower melting I²t (209.88). Both maintain 8A current rating and 5x20mm package.

Q: Can OptiFuse TCC-8A replace 0215008.TXP in all applications? A: TCC-8A maintains 8A current rating, 250VAC voltage, slow-blow response, and 5x20mm package. However, breaking capacity is significantly lower (200A vs. 1.5kA). Application circuit protection requirements must be verified before substitution.

Q: Are all substitute parts certified to the same standards? A: Littelfuse parts carry CE, CSA, KC, PSE, SEMKO, UL, VDE certifications. SCHURTER parts carry cURus and VDE certifications. OptiFuse TCC-8A carries cULus and UL 248 certifications; TCD-8A carries cURus and IEC 60127 certifications. Application compliance requirements determine acceptable substitutes.

Q: What is the significance of melting I²t values in fuse selection? A: Melting I²t indicates the thermal energy required to melt the fuse element. Littelfuse and OptiFuse TCD-8A specify 209.88 and unspecified values respectively; SCHURTER and OptiFuse TCC-8A specify 268 and 75.422 respectively. Lower values indicate faster response to overcurrent conditions.

Q: Can these fuses be used in DC circuits? A: 0215008.TXP, 0215008.HXP, 0215008.MXP, TCC-8A, and TCD-8A are rated for AC/DC operation at 250VAC. SCHURTER parts (0001.2513, 0001.2713.11) explicitly support 150VDC operation. DC application voltage must not exceed rated specifications.
