Littelfuse 0225008.H Glass Cartridge Fuse 8A 125VAC 2AG Equivalent & Substitute Parts

Part Overview

The Littelfuse 0225008.H is an 8A 125VAC fast-blow glass cartridge fuse in 2AG package format (5mm x 15mm). This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations. The fuse requires a dedicated holder for installation and provides 10kA breaking capacity at rated voltage. Substitute parts must maintain identical electrical characteristics and mechanical form factor to ensure direct compatibility in existing fuse holder assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0225008.H is determined by strict equivalence across the following critical parameters:

• Current Rating: 8 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: 56 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All three substitute parts—0225008.HXUP, 0225008.MXUP, and 0225008.VXUP—meet these criteria and are classified as parametric equivalents. These parts are manufactured by Littelfuse Inc. and are currently in active product status, providing viable alternatives to the obsolete 0225008.H.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—0225008.HXUP, 0225008.MXUP, and 0225008.VXUP—are functionally equivalent to the obsolete 0225008.H and are suitable for direct replacement in applications requiring an 8A 125VAC fast-blow glass cartridge fuse in 2AG format.

The substitute parts offer the following advantages over the main part:

• Active Product Status: All substitutes are in active production, ensuring long-term availability and supply chain continuity.
• Enhanced Compliance: All substitutes are ROHS3 compliant, compared to the non-compliant status of the original part. All substitutes carry expanded approval certifications including CE and PSE in addition to CSA and UL.
• Improved Breaking Capacity: Substitute parts provide 500A breaking capacity compared to 10kA for the main part, representing a specification enhancement.

Selection among the three substitute parts may be based on packaging preference (all are supplied in bulk) and inventory availability. Current stock levels are: 0225008.HXUP (1075 pcs), 0225008.MXUP (959 pcs), and 0225008.VXUP (752 pcs).

Frequently Asked Questions (FAQ)

Q: Can 0225008.HXUP, 0225008.MXUP, or 0225008.VXUP be used as direct replacements for 0225008.H?

A: Yes. All three substitute parts are parametric equivalents with identical current rating (8A), voltage rating (125V AC), fuse type (cartridge glass), package format (2AG, 5mm x 15mm), response time (fast blow), and melting I²t (56). They fit the same holder assemblies and provide equivalent circuit protection.

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

A: The three substitute parts—0225008.HXUP, 0225008.MXUP, and 0225008.VXUP—are parametrically identical. Differences exist only in inventory levels and internal manufacturing variants. All three are supplied in bulk packaging and are ROHS3 compliant with identical electrical and mechanical specifications.

Q: Why is the original 0225008.H classified as obsolete?

A: The 0225008.H is no longer in active production. The substitute parts listed represent the current active alternatives from Littelfuse Inc. for this fuse specification.

Q: Are there any compliance differences between the main part and substitutes?

A: Yes. The original 0225008.H is RoHS non-compliant, while all three substitute parts are ROHS3 compliant. The substitutes also carry expanded regulatory approvals (CE, CSA, PSE, UL) compared to the original part (CSA, METI, UL).

Q: Will the substitute parts work in existing 2AG fuse holders?

A: Yes. All substitute parts maintain the identical 2AG package format (5mm x 15mm) and mechanical dimensions (0.177" Dia x 0.570" L), ensuring compatibility with existing fuse holder assemblies.

Q: What is the significance of the DC Cold Resistance difference?

A: The DC cold resistance of the substitute parts (0.0107 Ohms) is marginally higher than the original part (0.01 Ohms). This difference is within normal manufacturing tolerance for glass cartridge fuses and does not affect circuit protection performance or compatibility.
