Littelfuse 0224006.DRT2UP Equivalent & Substitute Parts

Part Overview

The Littelfuse 0224006.DRT2UP is a 6A 125VAC fast-blow glass cartridge fuse in 2AG package format (5mm x 15mm axial). This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component procurement. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and approval certifications to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 0224006.DRT2UP is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must match:

• Current rating: 6 A
• Voltage rating: 125 V AC
• Fuse type: Cartridge, Glass (fast-blow response)
• Package format: 2AG, 5mm x 15mm axial
• Breaking capacity: 500A
• Melting I²t: 22.1
• Approval certifications: CE, CSA, PSE, UL
• RoHS compliance: ROHS3

The primary difference between the main part and its substitute is packaging format (bulk vs. tape & reel) and product status (obsolete vs. active), with no impact on electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 0224006.DRT1UP is the direct equivalent for the obsolete 0224006.DRT2UP. Both parts are manufactured by Littelfuse and carry identical electrical specifications, mechanical dimensions, and regulatory certifications (CE, CSA, PSE, UL). The substitute part maintains active product status, ensuring continued availability and supply chain reliability.

The only functional difference is packaging format: the main part is supplied in bulk configuration, while the substitute is supplied in tape & reel format. This distinction affects procurement and assembly processes but does not impact electrical performance or circuit compatibility. Both parts are ROHS3 compliant and operate across the same temperature range (-55°C to 125°C).

Frequently Asked Questions (FAQ)

Q: Can 0224006.DRT1UP be used as a direct replacement for 0224006.DRT2UP?

A: Yes. Both parts are electrically and mechanically identical. They share the same 6A 125VAC rating, fast-blow response, 2AG package dimensions, and regulatory approvals. The only difference is packaging format (bulk vs. tape & reel).

Q: Does the tape & reel packaging affect circuit performance?

A: No. Packaging format is a procurement and assembly consideration only. Once installed, the fuse component performs identically regardless of original packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both 0224006.DRT2UP and 0224006.DRT1UP are ROHS3 compliant.

Q: What is the significance of the obsolete status?

A: The 0224006.DRT2UP is classified as obsolete, meaning Littelfuse no longer manufactures it. The 0224006.DRT1UP is active and remains in production, ensuring long-term availability for replacement and new designs.

Q: Are the regulatory certifications identical?

A: Yes. Both parts carry CE, CSA, PSE, and UL approvals, meeting the same international safety and performance standards.
