Littelfuse 0224006.HXW Glass Cartridge Fuse 6A 125VAC 2AG Equivalent & Substitute Parts

Part Overview

The Littelfuse 0224006.HXW is a 6A 125VAC glass cartridge fuse in 2AG package format (5mm x 15mm axial). This component is classified as obsolete. Due to its discontinued status, direct replacement with active production equivalents is necessary for new designs and ongoing system maintenance. The substitute parts listed maintain identical electrical and mechanical specifications while offering improved compliance and active product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0224006.HXW is based on strict equivalence across the following critical parameters:

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

All three substitute parts (0224006.HXUP, 0224006.MXUP, 0224006.VXUP) meet these criteria and are manufactured by Littelfuse Inc. within the same 224 series. These parts differ from the main part only in packaging format (Bulk vs. standard) and compliance certifications, with no impact on electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (0224006.HXUP, 0224006.MXUP, 0224006.VXUP) are direct functional equivalents of the 0224006.HXW with active product status. Selection among these three substitutes should be based on:

1. Product Status: All substitutes are active production parts, ensuring long-term availability and supply chain stability compared to the obsolete main part.

2. Compliance Requirements: All substitutes carry ROHS3 compliance and expanded certification coverage (CE, CSA, PSE, UL) compared to the main part (CSA, METI, UL). Organizations with regulatory requirements for RoHS3 compliance must use one of the substitute parts.

3. Inventory Availability: 0224006.MXUP (1013 Pcs), 0224006.VXUP (821 Pcs), and 0224006.HXUP (813 Pcs) are all available in stock.

4. DC Cold Resistance: Substitute parts exhibit 0.0154 Ohms versus 0.0147 Ohms in the main part. This minor variation remains within acceptable tolerance for 6A cartridge fuse applications.

5. Breaking Capacity: Substitute parts specify 500A breaking capacity at rated voltage, providing enhanced performance margin compared to the main part specification of 10kA.

Frequently Asked Questions (FAQ)

Q: Can 0224006.HXUP, 0224006.MXUP, or 0224006.VXUP be used as direct replacements for 0224006.HXW?

A: Yes. All three substitute parts are electrically and mechanically equivalent. They maintain identical current rating (6A), voltage rating (125V AC), fuse type (cartridge glass), package format (2AG, 5mm x 15mm), response time (fast blow), and operating temperature range (-55°C to 125°C). The substitutes are preferred due to active product status and improved compliance certifications.

Q: What is the difference between the three substitute parts?

A: The three substitute parts (0224006.HXUP, 0224006.MXUP, 0224006.VXUP) are parametrically identical. They differ only in packaging format (all listed as Bulk) and inventory levels. Selection can be based on availability and supply chain preferences.

Q: Why is the main part 0224006.HXW classified as obsolete?

A: The 0224006.HXW is no longer in active production. The substitute parts represent the current production equivalents within the Littelfuse 224 series and should be used for new designs and system replacements.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist for direct substitution. All parts share identical through-hole mounting, 2AG package dimensions, and electrical characteristics. PCB footprints and circuit designs require no modification.

Q: Does the slight difference in DC cold resistance (0.0147 Ohms vs. 0.0154 Ohms) affect circuit performance?

A: No. This variation of 0.0007 Ohms is negligible for 6A cartridge fuse applications and falls within normal manufacturing tolerance for this component category.

Q: Which substitute part should be selected for new designs?

A: Any of the three substitute parts (0224006.HXUP, 0224006.MXUP, 0224006.VXUP) is suitable for new designs. Selection should be based on internal supply chain preferences, inventory availability, and packaging requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant, whereas the main part 0224006.HXW is RoHS non-compliant. This is a significant advantage for applications subject to RoHS regulations.
