Engineering Selection Recommendations

Bel Fuse 5HFP 5-R (MFR Recommended Substitute)

The Bel Fuse 5HFP 5-R is designated as the manufacturer-recommended substitute for the Littelfuse 0216005.MXESPP. This part maintains all critical electrical and mechanical parameters including 5 A current rating, 250 V AC voltage rating, fast-blow response, 1.5 kA breaking capacity, and 5mm x 20mm ceramic cartridge form factor. The 5HFP 5-R carries Active product status and holds ROHS3 compliance. Approval certifications include CCC, CE, CSA, cULus, IMQ, PSE, SEMKO, and VDE. The melting I²t value of 39 and DC cold resistance of 0.016 Ohms represent minor variations within acceptable tolerance for this component category. Physical dimensions measure 0.217" Dia x 0.827" L (5.50mm x 21.00mm), representing a negligible dimensional variance suitable for standard through-hole mounting applications.

Conquer TUC UBM-P 5A 250V (PF) (Parametric Equivalent)

The Conquer TUC UBM-P 5A 250V (PF) is classified as a parametric equivalent substitute, meeting all critical electrical and mechanical specifications of the original part. This component delivers 5 A current rating, 250 V AC voltage rating, fast-blow response, 1.5 kA breaking capacity, and identical 5mm x 20mm ceramic cartridge configuration. The TUC UBM-P maintains Active product status and ROHS3 compliance with approval certifications including CCC, cURus, KC, PSE, and TUV. The melting I²t value of 27.63 and DC cold resistance of 0.0185 Ohms closely align with the original specification. Physical dimensions of 0.205" Dia x 0.787" L (5.20mm x 20.00mm) match the original part precisely, ensuring direct mechanical compatibility.

Both substitute parts are suitable for direct replacement in applications requiring 5 A 250 V AC/DC ceramic cartridge fuse protection with fast-blow characteristics and through-hole mounting configuration.

Frequently Asked Questions (FAQ)

Q: What determines if a fuse can substitute for the Littelfuse 0216005.MXESPP?

A: Substitution is determined by exact alignment of current rating (5 A), voltage rating (250 V AC), response time (fast-blow), breaking capacity (1.5 kA), fuse type (ceramic cartridge), package dimensions (5mm x 20mm axial), mounting type (through-hole), operating temperature range (-55°C ~ 125°C), and RoHS compliance status (ROHS3). All identified substitutes meet these criteria.

Q: Are there differences in melting I²t values between the main part and substitutes?

A: Yes. The Littelfuse 0216005.MXESPP has a melting I²t of 27.46, the Bel Fuse 5HFP 5-R has 39, and the Conquer TUC UBM-P has 27.63. These variations are within acceptable tolerance for ceramic cartridge fuses in this current and voltage class and do not affect functional substitution capability.

Q: Do the physical dimension variations affect mounting compatibility?

A: The Littelfuse 0216005.MXESPP measures 0.205" Dia x 0.787" L (5.20mm x 20.00mm). The Bel Fuse 5HFP 5-R measures 0.217" Dia x 0.827" L (5.50mm x 21.00mm), representing minor dimensional variance. The Conquer TUC UBM-P matches the original at 0.205" Dia x 0.787" L (5.20mm x 20.00mm). Standard through-hole fuse holders accommodate these dimensional tolerances without modification.

Q: What approval certifications are common across all three parts?

A: All three parts hold CE, PSE, and VDE certifications. The Littelfuse 0216005.MXESPP additionally carries CSA, CQC, KC, and UR approvals. The Bel Fuse 5HFP 5-R holds CCC, CSA, cULus, IMQ, and SEMKO certifications. The Conquer TUC UBM-P carries CCC, cURus, KC, and TUV certifications. Selection should consider application-specific regulatory requirements.

Q: Can DC cold resistance variations affect circuit performance?

A: DC cold resistance values are 0.0183 Ohms (Littelfuse), 0.016 Ohms (Bel Fuse), and 0.0185 Ohms (Conquer). These variations are negligible in typical circuit protection applications and do not impact functional substitution suitability.
