Littelfuse 0216.500TXP Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0216.500TXP is an active-status ceramic cartridge fuse rated at 500 mA, 250 V AC/DC with fast-blow response characteristics. This component is designed for circuit protection in applications requiring a 5mm x 20mm form factor with holder mounting. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, and performance specifications to ensure direct functional replacement in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0216.500TXP is determined by the following critical parameters:

• Current Rating: 500 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Engineering Selection Recommendations

All substitute parts listed are active-status components with full regulatory compliance. Selection among equivalent options may be based on inventory availability and supply chain considerations:

• Littelfuse 0216.500HXP and 0216.500MXP are parametric equivalents from the same manufacturer series (216), holding certifications including CCC, CE, CSA, SEMKO, UR, and VDE.
• SCHURTER 0001.1001 is a direct manufacturer equivalent from the SP 5x20 series with certifications including CCC, cURus, KC, and VDE.
• OptiFuse FCD-500MA is a parametric equivalent from the FCD series with IEC 60127 certification and explicit DC voltage rating of 250 V.

All parts meet the required electrical and mechanical specifications for direct substitution in 5mm x 20mm ceramic fuse holder applications.

Frequently Asked Questions (FAQ)

Q: Can the 0216.500HXP replace the 0216.500TXP in all applications?

A: Yes. Both parts are identical in current rating (500 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (fast blow), package dimensions (5mm x 20mm), breaking capacity (1.5 kA), and operating temperature range (-55°C to 125°C). They are direct parametric equivalents.

Q: What is the difference between Littelfuse and SCHURTER ceramic fuses in this category?

A: The SCHURTER 0001.1001 meets the same electrical and mechanical requirements as the Littelfuse options. Differences exist only in manufacturer series designation (SP 5x20 vs. 216) and specific regulatory certifications held. All are suitable for the same applications.

Q: Does the OptiFuse FCD-500MA have any advantage over the Littelfuse options?

A: The FCD-500MA explicitly specifies a 250 V DC rating, whereas the main part and other Littelfuse equivalents do not specify DC voltage. For applications requiring confirmed DC performance, the FCD-500MA provides explicit documentation. All other electrical and mechanical parameters are identical.

Q: Are all these fuses RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: Can these fuses be used interchangeably in existing fuse holders?

A: Yes. All substitute parts share the identical 5mm x 20mm package dimensions and require holder mounting, ensuring mechanical compatibility with existing fuse holder installations.
