Littelfuse 0313.010VXP Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0313.010VXP is a 10 mA, 250 V AC/DC slow-blow glass cartridge fuse designed for circuit protection in applications requiring precise current limiting. This fuse is housed in a 3AB/3AG form factor (1/4" x 1-1/4") and requires a compatible holder for installation. The part maintains active product status with full regulatory compliance including CE, CSA, and UL approvals. Substitute parts are identified to support procurement flexibility and inventory management when the primary part number is unavailable.

Substitute Part Grouping Explanation

Substitute parts for the 0313.010VXP are identified based on electrical and mechanical parameter equivalence within the Littelfuse 313 series. The substitution criteria are strictly limited to the following parameters:

• Current Rating: 10 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Breaking Capacity @ Rated Voltage: 35A (exact match required)
• Melting I²t: 0.000121 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• DC Cold Resistance: 4300 Ohms (exact match required)
• Approval Agencies: CE, CSA, UL (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison
