Littelfuse 0332009.HXP Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0332009.HXP is a 9A ceramic cartridge fuse rated for 250V AC and 125V DC operation. Designed for fast-blow response characteristics, this component is housed in a 3AB/3AG form factor (1/4" x 1-1/4") and requires a compatible fuse holder for installation. The part is classified as obsolete, making identification of active equivalent components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0332009.HXP is determined by strict alignment of the following electrical and mechanical parameters:

• Current Rating: 9 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)
• Mounting Type: Requires Holder (exact match required)

The Eaton BK/GBB-9-R meets all substitution criteria and is classified as an active product, providing continuity for applications currently using the obsolete Littelfuse component.

Parameter Comparison

Engineering Selection Recommendations

The Eaton BK/GBB-9-R is the qualified substitute for the obsolete Littelfuse 0332009.HXP. Both components are ROHS3 compliant and share identical electrical ratings and mechanical form factors. The Eaton component maintains active product status, ensuring availability for procurement and ongoing supply chain support.

The Littelfuse component carries CE, cULus, and PSE approvals, while the Eaton substitute carries CSA and UR approvals. Applications requiring specific regional certification should confirm that the Eaton component's approval agencies satisfy system-level compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/GBB-9-R be used as a direct replacement for the Littelfuse 0332009.HXP?

A: Yes. Both components share identical current ratings (9A), voltage ratings (250V AC / 125V DC), fuse type (ceramic cartridge), response time (fast blow), and mechanical package (3AB/3AG, 1/4" x 1-1/4"). Physical installation in existing fuse holders is compatible.

Q: What is the difference in DC cold resistance between these components?

A: The Littelfuse component has a DC cold resistance of 0.0077 Ohms, while the Eaton component measures 0.0107 Ohms. Both values are within acceptable ranges for ceramic cartridge fuses of this rating and do not affect functional substitution.

Q: Are there any certification differences between these parts?

A: The Littelfuse component carries CE, cULus, and PSE approvals. The Eaton component carries CSA and UR approvals. System-level compliance requirements should be evaluated to confirm the Eaton component's certifications are acceptable for the intended application.

Q: Why is the Littelfuse component listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Eaton BK/GBB-9-R provides functional continuity for existing applications and new designs requiring this fuse specification.

Q: Will the Eaton component fit in existing Littelfuse fuse holders?

A: Yes. Both components use the 3AB/3AG form factor with identical dimensions (0.250" diameter x 1.250" length). They are mechanically interchangeable in compatible fuse holders.
