VUC UBM 8A 250V Ceramic Fuse Cartridge - Equivalent & Substitute Parts

Part Overview

The VUC UBM 8A 250V is an 8 ampere, 250 volt AC ceramic fuse cartridge manufactured by Conquer. This fast-blow cartridge fuse is designed for 5mm x 20mm holder applications and operates across a temperature range of -55°C to 125°C. The part maintains active product status with 2053 units in current inventory. Ceramic fuse cartridges require compatible holders for installation and are essential protective components in electrical circuits. Alternative equivalent parts may be required due to supply chain considerations, regional availability, or specific certification requirements for end applications.

Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the VUC UBM 8A 250V ceramic fuse cartridge is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 8 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Ceramic
• Package / Case: 5mm x 20mm
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 1.5 kA
• Operating Temperature Range: -55°C ~ 125°C
• Mounting Type: Requires Holder

All substitute parts listed below meet these mandatory electrical and mechanical specifications. Substitution is valid when the replacement part maintains identical current rating, voltage rating, physical dimensions, breaking capacity, and thermal operating range. The ceramic cartridge construction and fast-blow response characteristic are preserved across all equivalent options.

Parameter Comparison

Engineering Selection Recommendations

All four ceramic fuse cartridge options maintain active product status and full ROHS3 compliance. Selection among these equivalent parts is based on certification requirements and regional regulatory approvals:

VUC UBM 8A 250V (Conquer): Holds CCC, CSA, PSE, UL, and VDE certifications. Primary choice for applications requiring UL or VDE approval in North American and European markets.

0001.1013 (SCHURTER Inc.): Certified under cURus, KC, PSE/JET, and VDE standards. Suitable for applications requiring Canadian (cURus) or Korean (KC) market compliance. Series designation SP 5x20.

0216008.MXP (Littelfuse Inc.): Carries CE, CSA, KC, PSE, SEMKO, TUV, and UR certifications. Broadest certification coverage including European (CE, TUV), North American (CSA, UR), and Asian (PSE, SEMKO, KC) standards. Series 216.

FCD-8A (OptiFuse): Certified to IEC 60127 standard with explicit 250V DC voltage rating. Suitable for applications requiring both AC and DC circuit protection. Series FCD.

All parts are electrically and mechanically interchangeable within the specified 5mm x 20mm holder systems. Inventory availability ranges from 2053 to 5147 units across manufacturers.

Frequently Asked Questions (FAQ)

Q: Can the VUC UBM 8A 250V be directly replaced with any of these substitute parts?

A: Yes. All substitute parts meet identical electrical specifications: 8A current rating, 250V AC voltage rating, 1.5kA breaking capacity, fast-blow response, and 5mm x 20mm physical dimensions. Direct mechanical and electrical substitution is valid within any compatible 5mm x 20mm fuse holder.

Q: What is the difference in melting I²t values among these parts?

A: Melting I²t values vary: VUC UBM (91.5381), SCHURTER 0001.1013 (81.9), Littelfuse 0216008.MXP (64.315), and OptiFuse FCD-8A (102.2). These values represent thermal energy required to melt the fuse element. All parts maintain the same 8A current rating and fast-blow response characteristic despite I²t variation.

Q: Are there DC voltage considerations for these fuses?

A: The VUC UBM 8A 250V and SCHURTER 0001.1013 specify AC voltage ratings only. Littelfuse 0216008.MXP does not specify DC rating. OptiFuse FCD-8A explicitly rates 250V DC in addition to 250V AC, making it suitable for dual AC/DC circuit applications.

Q: What certifications should I verify for my application?

A: Certification requirements depend on end-use market. UL and VDE certifications apply to North American and European markets respectively. CSA applies to Canadian markets. PSE, KC, and SEMKO apply to Asian markets. Select the substitute part whose certification portfolio matches your application's regulatory requirements.

Q: Can these fuses be used interchangeably in the same holder?

A: Yes. All parts share identical 5mm x 20mm physical dimensions (0.205" diameter x 0.787" length) and require the same holder type. Mechanical fit and electrical connection are identical across all four options.

Q: What is the operating temperature range for all these fuses?

A: All four ceramic fuse cartridges operate across -55°C to 125°C temperature range, ensuring consistent performance across industrial and commercial thermal environments.
