Littelfuse 0FHA0010Z Fuse Holder Blade 32V 10A In-Line

Part Overview

The Littelfuse 0FHA0010Z is a blade fuse holder rated for 10A at 32V, designed for in-line mounting applications with free-hanging wire lead termination. This component is classified as obsolete, making identification of compatible alternatives essential for ongoing system maintenance and component procurement.

The FHA series holder accommodates standard ATC and ATO blade fuses with dimensions of 0.75" L x 0.2" W (19.1mm x 5.1mm). Due to its obsolete status, sourcing direct replacements requires evaluation of functionally equivalent alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Littelfuse 0FHA0010Z is determined by the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

• Voltage Rating: 32V (electrical safety requirement)
• Fuse Type: Blade (mechanical and electrical interface requirement)
• Fuse Size: 0.75" L x 0.2" W / 19.1mm x 5.1mm (physical fit requirement)
• Mounting Type: Free Hanging (In-Line) (installation configuration requirement)
• Number of Circuits: 1 (functional requirement)
• Termination Style: Wire Leads (connection interface requirement)
• Compatible Fuse Standards: ATC, ATO (fuse compatibility requirement)

Allowable Variation:

• Current Rating: The substitute part may have a higher current rating than the original 10A specification, provided the application circuit design permits this variation. The Eaton Bussmann BK/HHC-R substitute is rated for 16A, which is compatible with the same 32V, blade fuse holder form factor and mounting configuration.

The BK/HHC-R from Eaton - Bussmann Electrical Division meets all mandatory parameters and represents a direct functional substitute with enhanced current capacity.

Parameter Comparison

Engineering Selection Recommendations

The Eaton - Bussmann Electrical Division BK/HHC-R is the designated substitute for the obsolete Littelfuse 0FHA0010Z. Selection is based on the following engineering criteria:

Product Status Alignment: The BK/HHC-R maintains active product status, ensuring ongoing availability and manufacturer support, whereas the original part is obsolete.

Electrical Compliance: Both components are ROHS3 compliant, maintaining regulatory alignment for applications subject to hazardous substance restrictions.

Functional Equivalence: The BK/HHC-R preserves all critical electrical and mechanical parameters: 32V voltage rating, blade fuse type, standard ATC/ATO fuse compatibility, 0.75" x 0.2" fuse size, free-hanging in-line mounting, single-circuit configuration, and wire lead termination.

Current Rating Consideration: The BK/HHC-R is rated for 16A compared to the original 10A rating. This higher current capacity is compatible with the same physical form factor and voltage specification. Circuit design must accommodate this specification change if the application requires current limiting at the original 10A threshold.

Frequently Asked Questions (FAQ)

Q: Can the Eaton BK/HHC-R directly replace the Littelfuse 0FHA0010Z in existing assemblies?

A: Yes, the BK/HHC-R is mechanically and electrically compatible. Both components share identical fuse size (0.75" x 0.2"), voltage rating (32V), mounting configuration (free-hanging in-line), and wire lead termination. Physical installation and electrical connection are interchangeable.

Q: Does the higher 16A current rating of the BK/HHC-R affect compatibility?

A: The BK/HHC-R's 16A rating is compatible with the same 32V blade fuse holder specification. The current rating of the fuse holder itself does not limit the fuses that can be installed; rather, the fuse inserted into the holder determines the circuit protection level. Applications originally designed for 10A protection must use 10A fuses with the BK/HHC-R to maintain the intended protection threshold.

Q: Are there packaging differences between these components?

A: The Littelfuse 0FHA0010Z is available in standard packaging, while the Eaton BK/HHC-R is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: What compliance certifications apply to the substitute part?

A: The Eaton BK/HHC-R is ROHS3 compliant and REACH unaffected, matching the regulatory status of the original Littelfuse component.

Q: Are both components compatible with ATC and ATO blade fuses?

A: Yes, both the Littelfuse 0FHA0010Z and Eaton BK/HHC-R are designed for use with standard ATC and ATO blade fuses of the specified 0.75" x 0.2" dimension.
