Littelfuse 02183.15MXEP Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 02183.15MXEP is a 3.15 A, 250 V AC/DC slow-blow glass cartridge fuse in 5mm x 20mm axial package configuration. This component is classified as Active product status and is designed for through-hole mounting applications requiring circuit protection in the specified current and voltage range. Equivalent and substitute parts are identified when identical electrical parameters and mechanical form factors are maintained across different manufacturers or product series, ensuring functional interchangeability within the same application context.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (3.15 A), voltage rating (250 V AC), fuse type (cartridge glass), response time (slow blow), package dimensions (5mm x 20mm axial), and mounting type (through hole). All identified substitute parts maintain these core electrical and mechanical specifications. Variations in breaking capacity, melting I²t, DC cold resistance, and approval agency certifications do not disqualify substitution when the primary protective function parameters remain identical. Parts are grouped by manufacturer while maintaining full parametric equivalence to the main part number.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance. Selection among equivalent parts should be based on approval agency requirements specific to the target application. The Littelfuse 02183.15MXEP carries UL and K-MARK certifications; the Littelfuse 02193.15MXAEP offers enhanced breaking capacity (150 A versus 35 A) while maintaining identical electrical ratings. The SCHURTER 0034.3122.PT and Bel Fuse 5STP 3.15-R are direct cross-manufacturer alternatives with cURus certification. Inventory availability and regional certification requirements should guide final part selection when multiple equivalents are available.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 02133.15MXEP replace the 02183.15MXEP in all applications? A: Yes. Both parts share identical current rating (3.15 A), voltage rating (250 V AC), response time (slow blow), and package configuration (5mm x 20mm axial). Differences in melting I²t and DC cold resistance do not affect substitution eligibility when core protective parameters are maintained.

Q: What is the significance of the higher breaking capacity in the 02193.15MXAEP? A: The 02193.15MXAEP provides 150 A breaking capacity compared to 35 A in the main part. This represents enhanced fault current handling capability. The part remains electrically equivalent for normal operation at 3.15 A, 250 V AC.

Q: Are cross-manufacturer substitutes (SCHURTER, Bel Fuse) fully compatible? A: Yes. The SCHURTER 0034.3122.PT and Bel Fuse 5STP 3.15-R maintain identical electrical specifications and package dimensions. Verify that required approval agencies (cURus, CE, VDE) align with application requirements before selection.

Q: Does package dimension variation affect substitution? A: Physical dimensions vary slightly across manufacturers (5.40mm to 5.80mm diameter; 21.00mm to 22.50mm length). These variations remain within the 5mm x 20mm nominal specification and do not prevent mechanical or electrical substitution in standard through-hole mounting applications.

Q: What certifications should I verify for my specific application? A: Identify required certifications for your target market or application standard. The main part carries CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, and VDE. Cross-reference substitute part certifications to ensure compliance with regional or industry-specific requirements.
