Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5ETP 3.15-R is determined by the following mandatory parameters:

• Current Rating: 3.15 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm nominal dimensions (axial through-hole)
• Operating Temperature Range: -55°C ~ 125°C (minimum coverage required)
• RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

All substitute parts listed meet these core electrical and mechanical criteria. Variations in breaking capacity, melting I²t, physical dimensions within tolerance, and approval agency certifications do not disqualify substitution but may affect application-specific performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and meet the mandatory electrical and mechanical parameters for direct substitution with the 5ETP 3.15-R.

5STP 3.15-R (Bel Fuse Inc.): Parametric equivalent from the same manufacturer. Shares identical current rating, voltage, fuse type, response time, and package specifications. Breaking capacity is 35 A versus 150 A on the main part. Approval agencies include CCC, CE, CSA, cURus, IMQ, SEMKO, and VDE. Inventory availability is 2238 units.

02193.15MXAEP (Littelfuse Inc.): Direct manufacturer equivalent with matching breaking capacity (150 A) and melting I²t (202) to the main part. Physical dimensions are 5.80mm x 22.50mm, within nominal tolerance for 5mm x 20mm package classification. Approval agencies include CCC, CE, CSA, PSE, SEMKO, UL, and VDE. Inventory availability is 10395 units.

02183.15MXEP (Littelfuse Inc.): Similar substitute with breaking capacity of 35 A and melting I²t of 38.15. Physical dimensions are 5.80mm x 22.50mm. Approval agencies include CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, and VDE. Inventory availability is 3185 units.

Selection should be based on application requirements for breaking capacity, circuit protection characteristics, and regional certification requirements.

Frequently Asked Questions (FAQ)

Q: Can 5STP 3.15-R be used as a direct replacement for 5ETP 3.15-R?

A: Yes. Both parts share identical current rating (3.15 A), voltage rating (250 V AC), fuse type (cartridge glass), response time (slow blow), and package dimensions (5mm x 20mm axial). The primary difference is breaking capacity: 5STP has 35 A versus 5ETP's 150 A. Selection depends on circuit protection requirements.

Q: What is the difference between Littelfuse 02193.15MXAEP and 02183.15MXEP?

A: Both are 3.15 A, 250 V slow-blow glass cartridge fuses in 5mm x 20mm packages. The 02193.15MXAEP has breaking capacity of 150 A and melting I²t of 202, matching the main part's performance. The 02183.15MXEP has breaking capacity of 35 A and melting I²t of 38.15. Physical dimensions differ slightly (5.80mm x 22.50mm versus nominal 5mm x 20mm), but both fit standard 5mm x 20mm through-hole footprints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and meet the same regulatory standard as the 5ETP 3.15-R.

Q: What approval agencies are common across all parts?

A: CCC, CE, CSA, SEMKO, and VDE certifications are present on all listed parts. Additional regional certifications vary by manufacturer and series.

Q: Can physical dimension variations affect PCB compatibility?

A: The 5ETP 3.15-R measures 5.50mm x 21.00mm. Littelfuse substitutes measure 5.80mm x 22.50mm. Both dimensions fall within the nominal 5mm x 20mm package classification and are compatible with standard through-hole footprints designed for axial cartridge fuses in this size category. Verify PCB layout clearances for specific applications.
