TUC UBM-P 8A 250V Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The TUC UBM-P 8A 250V is an active ceramic cartridge fuse designed for through-hole mounting in 5mm x 20mm form factor. This fast-blow fuse operates at 8 amperes with 250 volts AC/DC rating and provides 1.5kA breaking capacity. The component is manufactured by Conquer and maintains full RoHS3 compliance with international certifications including CCC, cURus, KC, PSE, and TUV approval. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same fuse category, enabling component interchangeability in circuit protection applications.

• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)

Compliance Parameters:

• RoHS3 Compliant (required)
• Operating Temperature Range: -55°C ~ 125°C (required)

The substitute part 0216008.MXESPP (Littelfuse Inc., 216SP series) meets all mandatory electrical, mechanical, and compliance criteria for direct substitution in applications requiring the TUC UBM-P 8A 250V ceramic fuse.

Parameter Comparison

Engineering Selection Recommendations

Both the TUC UBM-P 8A 250V and the 0216008.MXESPP substitute part maintain active product status with full RoHS3 compliance. The primary electrical and mechanical parameters are identical, ensuring functional equivalence in circuit protection applications requiring 8A/250V fast-blow ceramic cartridge fuses in 5mm x 20mm through-hole configuration.

The TUC UBM-P 8A 250V carries certifications from CCC, cURus, KC, PSE, and TUV. The substitute part 0216008.MXESPP carries certifications from CE, CSA, CQC, PSE, and UR. Both parts satisfy international safety and compliance requirements for their respective markets.

Minor variations exist in DC cold resistance (0.0098 Ohms versus 0.0123 Ohms) and melting I²t values (79.488 versus 64.315), which remain within acceptable tolerance for ceramic cartridge fuse performance characteristics and do not affect substitution eligibility based on the provided electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the 0216008.MXESPP substitute for the TUC UBM-P 8A 250V in all applications?

A: Yes. Both parts are ceramic cartridge fuses with identical current rating (8A), voltage rating (250V AC), response time (fast blow), breaking capacity (1.5kA), and physical dimensions (5mm x 20mm). Both operate across the same temperature range (-55°C ~ 125°C) and are RoHS3 compliant. They are functionally equivalent for through-hole mounting applications.

Q: Are there differences in certification between these two parts?

A: Yes. The TUC UBM-P 8A 250V carries CCC, cURus, KC, PSE, and TUV certifications. The 0216008.MXESPP carries CE, CSA, CQC, PSE, and UR certifications. Both parts meet international safety standards. Verify that the certifications of the substitute part align with your specific regional or application requirements.

Q: What is the significance of the DC cold resistance difference?

A: The DC cold resistance values (0.0098 Ohms for TUC UBM-P versus 0.0123 Ohms for 0216008.MXESPP) represent minor manufacturing variations within ceramic fuse specifications. Both values are within acceptable ranges for 8A ceramic cartridge fuses and do not affect circuit protection performance or substitution eligibility.

Q: Do both parts have the same melting I²t characteristic?

A: No. The TUC UBM-P 8A 250V has a melting I²t of 79.488, while the 0216008.MXESPP has a melting I²t of 64.315. Both values are characteristic of fast-blow ceramic fuses in this amperage class. The difference reflects normal manufacturing variation between manufacturers and does not prevent substitution for standard circuit protection applications.

Q: Are both parts currently available?

A: Yes. Both parts maintain active product status. The TUC UBM-P 8A 250V has 2040 pieces in stock, and the 0216008.MXESPP has 4762 pieces in stock.
