Frequently Asked Questions (FAQ)

Q: Can the 0315005.HXP directly replace the 0315005.VXP in existing designs?

A: Yes. Both parts share identical current rating (5 A), voltage rating (250 V AC), response time (Slow Blow), package format (3AB, 3AG), and all thermal and electrical characteristics. No circuit modification is required.

Q: Are there differences in approval certifications between these parts?

A: Both parts carry CE, CSA, PSE, and UL certifications. The 0315005.HXP includes additional K-MARK certification. This does not affect electrical or mechanical compatibility.

Q: What is the significance of the 3AB/3AG package designation?

A: The 3AB/3AG package specifies the physical form factor (1/4" x 1-1/4" axial cartridge) and electrical performance class. Both substitute parts maintain this identical package specification, ensuring mechanical fit in standard fuse holders.

Q: Are both parts suitable for AC and DC applications?

A: Yes. Both parts are rated for 250 V AC/DC operation with identical DC cold resistance (0.0214 Ohms) and melting I²t characteristics (140).

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

A: Both parts operate across -55°C to 125°C, maintaining consistent performance across this full temperature range.
