Littelfuse 0225006.H Glass Cartridge Fuse 6A 125VAC 2AG Equivalent & Substitute Parts

Part Overview

The Littelfuse 0225006.H is a 6A 125VAC fast-blow glass cartridge fuse in 2AG package format (5mm x 15mm). This component is classified as obsolete, requiring identification of active equivalent alternatives for continued circuit protection applications. The part requires a dedicated fuse holder for installation and operates across a temperature range of -55°C to 125°C. Substitute parts must maintain identical electrical and mechanical specifications to ensure proper circuit protection without modification to existing fuse holder assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0225006.H are qualified 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)
• Melting I²t: 22.1 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Physical Dimensions: 0.177" Dia x 0.570" L (exact match required)

All three substitute parts (0225006.HXUP, 0225006.MXUP, 0225006.VXUP) meet these criteria and are manufactured by Littelfuse Inc. within the same 225 series. These parts are direct parametric equivalents suitable for one-to-one replacement in existing 2AG fuse holder assemblies.

Parameter Comparison

Engineering Selection Recommendations

The original part 0225006.H is classified as obsolete and should be replaced with an active equivalent for new designs and ongoing production. All three substitute parts (0225006.HXUP, 0225006.MXUP, 0225006.VXUP) are active products manufactured by Littelfuse Inc. and provide identical electrical and mechanical performance.

The substitute parts offer improved compliance status compared to the original:

• All substitutes are ROHS3 compliant, whereas the original is RoHS non-compliant
• All substitutes carry expanded approval certifications (CE, CSA, PSE, UL) compared to the original (CSA, METI, UL)
• All substitutes are available in bulk packaging with higher inventory levels

Selection among the three active substitutes should be based on availability and packaging requirements, as all three are parametric equivalents with identical electrical characteristics and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can 0225006.HXUP, 0225006.MXUP, and 0225006.VXUP be used interchangeably with 0225006.H?

A: Yes. All three substitute parts are direct parametric equivalents with identical current rating (6A), voltage rating (125V AC), fuse type (cartridge glass), package format (2AG, 5mm x 15mm), response time (fast blow), and melting I²t (22.1). They are suitable for one-to-one replacement in existing 2AG fuse holder assemblies.

Q: What is the difference between the original 0225006.H and the substitute parts?

A: The primary differences are product status and compliance. The original is obsolete and RoHS non-compliant. All substitutes are active products with ROHS3 compliance and expanded regulatory certifications (CE, CSA, PSE, UL). DC cold resistance shows a minor variation (0.0147 Ohms vs. 0.0154 Ohms), which does not affect circuit protection performance.

Q: Are there any compatibility concerns when replacing 0225006.H with these substitutes?

A: No compatibility concerns exist. The substitute parts maintain identical physical dimensions (0.177" Dia x 0.570" L) and package format (2AG), ensuring direct installation in existing fuse holders without modification.

Q: Which substitute part should be selected if all three are equivalent?

A: Selection should be based on availability and packaging preference. All three parts (0225006.HXUP, 0225006.MXUP, 0225006.VXUP) are active Littelfuse products with identical electrical and mechanical specifications. Inventory levels are 854 pcs, 1797 pcs, and 975 pcs respectively.

Q: Does the DC cold resistance difference affect circuit protection?

A: No. The DC cold resistance variation between the original (0.0147 Ohms) and substitutes (0.0154 Ohms) is negligible and does not impact fuse operation or circuit protection characteristics. The melting I²t value of 22.1 remains identical across all parts.
