Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0473003.VXL are identified based on strict equivalence across the following critical parameters:

• Current Rating: 3 A
• Voltage Rating: 125 V AC / 125 V DC
• Response Time: Slow Blow
• Mounting Type: Through Hole
• Package / Case: Axial
• Breaking Capacity @ Rated Voltage: 50 A
• Melting I²t: 21
• Physical Dimensions: 0.135" Dia x 0.280" L (3.43mm x 7.11mm)
• DC Cold Resistance: 0.038 Ohms
• Regulatory Compliance: CSA, PSE, UR certifications

Parts meeting all these specifications are classified as parametric equivalents and may be used interchangeably in circuit protection applications where the 0473003.VXL is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the 0473003.VXL and 0473003.MXL are active products manufactured by Littelfuse Inc. within the PICO® II 473 series. Selection between these parts may be based on procurement availability, lead time, or inventory status. Both components carry identical regulatory certifications (CSA, PSE, UR) and comply with ROHS3 requirements. The parametric equivalence ensures functional interchangeability in circuit protection applications requiring 3A slow-blow fuse protection at 125VAC/VDC ratings.

Frequently Asked Questions (FAQ)

Q: Can the 0473003.MXL be used as a direct replacement for the 0473003.VXL?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (3A, 125VAC/VDC), response characteristics (slow blow), mechanical dimensions (0.135" Dia x 0.280" L), and regulatory certifications. They are interchangeable in applications where the 0473003.VXL is specified.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by equivalence in current rating (3A), voltage rating (125V AC/DC), response time (slow blow), mounting configuration (through hole axial), breaking capacity (50A), melting I²t (21), physical dimensions, and regulatory approvals (CSA, PSE, UR).

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bulk packaging and maintain identical axial through-hole configurations. No packaging or form factor differences exist between the 0473003.VXL and 0473003.MXL.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components carry CSA, PSE, and UR certifications and are ROHS3 compliant. REACH status is unaffected for both parts.

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

A: Both the 0473003.VXL and 0473003.MXL operate across the temperature range of -55°C to 125°C.
