Littelfuse 0326.010VXP Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0326.010VXP is a 10 mA ceramic cartridge fuse rated for 250 V AC/DC operation. This slow-blow fuse is designed for applications requiring circuit protection in the 3AB and 3AG holder formats with dimensions of 1/4" x 1-1/4" (6.35mm x 31.75mm). The part maintains Active product status and is RoHS3 compliant with REACH unaffected classification. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same fuse category and holder requirements.

Substitute Part Grouping Explanation

Substitution for the 0326.010VXP is determined by strict equivalence across the following critical parameters:

• Current Rating: 10 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Breaking Capacity: 100 A (exact match required)
• Melting I²t: 0.00148 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The substitute part 0326.010HXP meets all these criteria and is therefore electrically and mechanically interchangeable with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

Both the 0326.010VXP and 0326.010HXP are Active status products manufactured by Littelfuse within the 326 series. The 0326.010HXP provides expanded regulatory approvals including CSA, ICC, PSE, SEMKO, TUV, UR, and VDE certifications in addition to CE marking, whereas the primary part carries CE approval. Both parts maintain identical electrical characteristics, mechanical dimensions, and thermal operating ranges. Selection between these parts should be based on the specific regulatory requirements of the target application and regional compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the 0326.010HXP replace the 0326.010VXP in all applications?

A: Yes, the 0326.010HXP is electrically and mechanically equivalent to the 0326.010VXP. Both parts share identical current ratings, voltage ratings, fuse type, response time, package dimensions, breaking capacity, and thermal characteristics. The primary difference is the expanded certification scope of the 0326.010HXP.

Q: What holder types are compatible with these fuses?

A: Both fuses are designed for 3AB and 3AG holder formats with dimensions of 1/4" x 1-1/4" (6.35mm x 31.75mm). Ensure the holder matches these specifications for proper installation and operation.

Q: Are there differences in regulatory compliance between these parts?

A: The 0326.010HXP carries additional regulatory approvals (CSA, ICC, PSE, SEMKO, TUV, UR, VDE) beyond the CE marking present on the 0326.010VXP. Applications requiring specific regional certifications should reference the appropriate part number.

Q: What is the significance of the Slow Blow response time?

A: Slow Blow fuses tolerate temporary inrush currents without nuisance tripping, making them suitable for circuits with transient current spikes. Both substitute parts maintain this characteristic.

Q: Are these fuses RoHS compliant?

A: Yes, both the 0326.010VXP and 0326.010HXP are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component manufacturing.
