Substitute Part Grouping Explanation

The Littelfuse 0224006.DRT1UP serves as the direct substitute for the obsolete 0224006.DRT3UP. Substitution is valid based on identical alignment across all critical electrical and mechanical parameters:

• Current Rating: 6 A (identical)
• Voltage Rating: 125 V AC (identical)
• Fuse Type: Cartridge, Glass (identical)
• Package Format: 2AG, 5mm x 15mm (identical)
• Response Time: Fast Blow (identical)
• Breaking Capacity: 500 A (identical)
• Melting I²t: 22.1 (identical)
• Operating Temperature: -55°C to 125°C (identical)
• DC Cold Resistance: 0.0154 Ohms (identical)
• Regulatory Compliance: CE, CSA, PSE, UL (identical)
• RoHS Status: ROHS3 Compliant (identical)

The primary distinction is product status and packaging configuration. The substitute part is active and available in Tape & Reel (TR) packaging, whereas the original part is obsolete and supplied in bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 0224006.DRT1UP is the appropriate selection for applications currently specified with the 0224006.DRT3UP. Both parts are manufactured by Littelfuse Inc. and carry identical regulatory certifications (CE, CSA, PSE, UL) and RoHS3 compliance status. The substitute part is active and maintains full availability through standard distribution channels, eliminating obsolescence risk.

The packaging difference (Tape & Reel versus bulk) does not affect electrical or mechanical performance. Selection between these packaging formats depends on assembly process requirements and procurement volume specifications.

Frequently Asked Questions (FAQ)

Q: Can the 0224006.DRT1UP directly replace the 0224006.DRT3UP in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including current rating, voltage rating, response time, breaking capacity, and physical dimensions. Direct substitution is valid.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging configuration. The 0224006.DRT3UP is obsolete and supplied in bulk packaging. The 0224006.DRT1UP is an active product supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes.

Q: Are the regulatory certifications identical?

A: Yes. Both parts carry CE, CSA, PSE, and UL certifications and are ROHS3 compliant. No compliance differences exist between the two parts.

Q: Does the 2AG package format remain the same?

A: Yes. Both parts use the 2AG package format with dimensions of 5mm x 15mm (axial). Physical fit and mounting are identical.

Q: What is the melting I²t value, and is it the same for both parts?

A: The melting I²t is 22.1 for both parts. This parameter defines the thermal energy required to melt the fuse element and is critical for circuit protection coordination.

Q: Are there any temperature or environmental differences?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C and have the same DC cold resistance of 0.0154 Ohms.
