5HF 315 Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The 5HF 315 is a 315 mA ceramic cartridge fuse rated for 250 V AC/DC operation in a 5mm x 20mm form factor, manufactured by Bel Fuse Inc. This component is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs. The fuse provides fast-blow response characteristics with a breaking capacity of 1.5 kA at rated voltage and operates across a temperature range of -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5HF 315 is based on strict electrical and mechanical parameter matching. All substitute parts must meet the following criteria:

• Current Rating: 315 mA (exact match)
• Voltage Rating: 250 V AC (exact match)
• Fuse Type: Cartridge, Ceramic (exact match)
• Package / Case: 5mm x 20mm (exact match)
• Response Time: Fast Blow (exact match)
• Breaking Capacity: 1.5 kA at rated voltage (exact match)
• Operating Temperature: -55°C to 125°C (exact match)
• Mounting Type: Requires Holder (exact match)

The substitute parts listed below are manufactured by Littelfuse Inc. under the 216 series and maintain full electrical and mechanical compatibility with the original 5HF 315 specification.

Parameter Comparison

Engineering Selection Recommendations

All four Littelfuse 216 series substitutes (0216.315HXP, 0216.315MXP, 0216.315TXP, 0216.315VXP) provide direct electrical and mechanical equivalence to the obsolete 5HF 315. Selection among these substitutes should be based on:

• Product Status: All substitute parts are active and currently manufactured, ensuring long-term availability compared to the obsolete 5HF 315.
• Regulatory Compliance: All substitutes are ROHS3 compliant and carry expanded approval certifications (CCC, CE, CSA, SEMKO, UR, VDE) compared to the original part, supporting compliance requirements in modern applications.
• Inventory Availability: Littelfuse 216 series parts maintain higher stock levels (825–1451 pcs) compared to the 5HF 315 (643 pcs).

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0216.315MXP, 0216.315HXP, 0216.315TXP, or 0216.315VXP be used as direct replacements for the 5HF 315?

A: Yes. All four Littelfuse substitutes match the 5HF 315 in current rating (315 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), package dimensions (5mm x 20mm), response time (fast blow), breaking capacity (1.5 kA), and operating temperature range (-55°C to 125°C). They are mechanically and electrically interchangeable.

Q: What is the difference between the four Littelfuse substitute part numbers?

A: The part numbers 0216.315HXP, 0216.315MXP, 0216.315TXP, and 0216.315VXP are variants within the Littelfuse 216 series. All share identical electrical specifications and package dimensions. Differences are limited to internal construction or manufacturing process variants that do not affect functional performance in this application.

Q: Does the fuse require a specific holder?

A: Yes. The 5HF 315 and all substitute parts require a fuse holder rated for 5mm x 20mm cartridge fuses. The fuse cannot be used without an appropriate holder assembly.

Q: Are the substitute parts RoHS compliant?

A: Yes. All Littelfuse 216 series substitutes are ROHS3 compliant, whereas the original 5HF 315 is RoHS non-compliant. This makes the substitutes suitable for applications with RoHS compliance requirements.

Q: What certifications do the substitute parts carry?

A: The Littelfuse 0216.315HXP, 0216.315MXP, 0216.315TXP, and 0216.315VXP carry CCC, CE, CSA, SEMKO, UR, and VDE approvals, providing broader regulatory coverage than the original 5HF 315.
