Littelfuse 0332006.HXP Ceramic Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0332006.HXP is a 6 A ceramic cartridge fuse rated for 250 V AC and 125 V DC operation. This component is classified as obsolete, requiring identification of active equivalent alternatives for continued system support. The fuse features fast-blow response characteristics and is designed for 3AB, 3AG holder compatibility with dimensions of 0.250" diameter by 1.250" length. Substitution is necessary due to the obsolete product status while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0332006.HXP is based on strict equivalence across the following critical parameters:

• Current Rating: 6 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria and are manufactured by Littelfuse Inc. The primary distinction between the obsolete 0332006.HXP (Series 332) and its active equivalents (Series 314) is product status and enhanced breaking capacity specifications, while maintaining identical core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (0314006.HXP, 0314006.MXP, 0314006.VXP) are direct functional equivalents to the obsolete 0332006.HXP. Selection among these active alternatives should be based on the following factors:

Product Status: All substitute parts carry Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete 0332006.HXP.

Regulatory Compliance: The 0314006.HXP, 0314006.MXP, and 0314006.VXP all maintain ROHS3 compliance and carry expanded approval certifications. The 0314006.HXP and 0314006.MXP include CSA and K-MARK approvals, while 0314006.VXP includes KC approval. All three include CE, PSE, and UL certifications.

Breaking Capacity: The substitute parts provide enhanced breaking capacity specifications (750A AC, 10kA DC) compared to the main part (100A), offering improved performance margins in fault conditions while maintaining identical current and voltage ratings.

Packaging: All substitute parts are supplied in Bulk packaging, consistent with standard distribution formats for active components.

Frequently Asked Questions (FAQ)

Q: Can the 0314006.HXP, 0314006.MXP, or 0314006.VXP be used as direct replacements for the 0332006.HXP?

A: Yes. All three substitute parts are electrically and mechanically equivalent. They share identical current ratings (6 A), voltage ratings (250 V AC, 125 V DC), fuse type (Cartridge, Ceramic), response time (Fast Blow), package designation (3AB, 3AG), and physical dimensions (0.250" Dia x 1.250" L). They are compatible with the same holder assemblies.

Q: What is the primary difference between the 0332006.HXP and the substitute parts?

A: The 0332006.HXP is classified as Obsolete (Series 332), while the substitute parts are Active (Series 314). The substitute parts also feature enhanced breaking capacity specifications (750A AC, 10kA DC versus 100A) and expanded regulatory approvals, while maintaining identical core electrical and mechanical specifications.

Q: Are there differences among the three substitute parts?

A: The 0314006.HXP, 0314006.MXP, and 0314006.VXP are parametrically equivalent. Minor differences exist in regulatory approval agencies: 0314006.HXP and 0314006.MXP include K-MARK certification, while 0314006.VXP includes KC certification. All three include CE, CSA, PSE, and UL approvals.

Q: Will the substitute parts fit existing 3AB and 3AG holders?

A: Yes. All substitute parts maintain the identical package designation (3AB, 3AG, 1/4" x 1-1/4") and physical dimensions (0.250" Dia x 1.250" L / 6.35mm x 31.75mm) as the original part, ensuring mechanical compatibility with existing holder assemblies.

Q: Are the substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, matching the compliance status of the original 0332006.HXP.
