Littelfuse 0224006.DRT1W Glass Cartridge Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0224006.DRT1W is a 6A 125VAC fast-blow glass cartridge fuse in the 2AG package format (5mm x 15mm axial). This through-hole mounted fuse is designed for circuit protection in AC and DC applications with a rated breaking capacity of 10kA at the specified voltage. The part is currently listed as obsolete, making identification of compatible substitutes essential for ongoing maintenance and repair operations. Active equivalent parts maintain identical electrical and mechanical specifications while offering improved availability and current compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0224006.DRT1W is determined by strict equivalence across the following critical parameters:

• Current Rating: Must be 6 A
• Voltage Rating (AC): Must be 125 V
• Fuse Type: Must be Cartridge, Glass
• Package / Case: Must be 2AG, 5mm x 15mm (Axial)
• Response Time: Must be Fast Blow
• Mounting Type: Must be Through Hole
• Operating Temperature Range: Must be -55°C ~ 125°C
• Melting I²t: Must be 22.1

The substitute part 0224006.DRT1UP meets all these criteria and is manufactured by the same supplier (Littelfuse Inc.), ensuring mechanical and electrical compatibility. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The 0224006.DRT1UP is the direct active equivalent for the obsolete 0224006.DRT1W. Both parts share identical electrical ratings (6A, 125VAC), fuse characteristics (fast-blow, glass cartridge), and mechanical specifications (2AG package, through-hole mounting). The substitute maintains the same operating temperature range and melting I²t value, ensuring functional equivalence in circuit protection applications.

The 0224006.DRT1UP offers improved compliance status with ROHS3 certification and expanded approval agency recognition (CE, PSE added to existing CSA, UL). The packaging difference (Tape & Reel versus bulk) reflects the active product status and does not affect electrical or mechanical compatibility. The minor variance in DC cold resistance (0.0154 Ohms versus 0.0147 Ohms) remains within acceptable tolerance for this component category and does not impact circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the 0224006.DRT1UP be used as a direct replacement for the 0224006.DRT1W?

A: Yes. Both parts are identical in current rating (6A), voltage rating (125VAC), fuse type (fast-blow glass cartridge), package format (2AG, 5mm x 15mm), and mounting configuration (through-hole). They are electrically and mechanically interchangeable.

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

A: The primary differences are product status and packaging. The 0224006.DRT1W is obsolete and supplied in bulk packaging, while the 0224006.DRT1UP is an active product supplied in Tape & Reel format. The 0224006.DRT1UP also carries ROHS3 compliance and additional regulatory certifications (CE, PSE).

Q: Does the packaging difference (Tape & Reel versus bulk) affect compatibility?

A: No. Packaging format is a supply and handling consideration only. It does not affect the electrical or mechanical performance of the fuse component itself.

Q: Are there any performance differences between these parts?

A: The DC cold resistance differs slightly (0.0147 Ohms versus 0.0154 Ohms), but this variance is within acceptable tolerance for glass cartridge fuses and does not impact circuit protection performance.

Q: Which certifications apply to the substitute part?

A: The 0224006.DRT1UP carries CE, CSA, PSE, and UL approvals, providing broader regulatory coverage than the original part.
