Equivalent & Substitute Parts for 0FHA0075Z

Part Overview

The 0FHA0075Z is a blade fuse holder manufactured by Littelfuse Inc., rated for 7.5 A at 32V with a single circuit configuration. This component is designed for free-hanging (in-line) mounting applications using ATC/ATO blade fuses with dimensions of 0.75" L x 0.2" W (19.1mm x 5.1mm). The product is classified as obsolete, necessitating identification of active equivalent components to maintain system functionality and ensure continued availability for new designs and repairs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0FHA0075Z is determined by the following critical parameters that must remain consistent:

• Voltage Rating: 32V (exact match required)
• Fuse Size: 0.75" L x 0.2" W (19.1mm x 5.1mm) (exact match required for mechanical compatibility)
• Fuse Type: Blade (ATC/ATO compatible)
• Number of Circuits: 1 (single circuit configuration)
• Mounting Type: Free Hanging (In-Line)
• Termination Style: Wire Leads

The current rating (7.5 A) is a functional parameter that may vary within the same physical form factor, provided the substitute holder accommodates the required fuse amperage rating. The BK/HHC-R substitute meets all mechanical and electrical compatibility requirements while offering an active product status with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The BK/HHC-R is a direct functional equivalent for the obsolete 0FHA0075Z. Both components share identical mechanical form factors, voltage ratings, and mounting configurations. The substitute maintains ROHS3 compliance and is actively manufactured by Eaton - Bussmann Electrical Division, ensuring long-term availability and supply chain continuity.

The higher current rating of the BK/HHC-R (16 A versus 7.5 A) reflects the holder's capacity rating rather than a functional limitation. The fuse holder itself accommodates fuses across this amperage range; the actual circuit protection is determined by the fuse element installed in the holder, not the holder's rated capacity. This characteristic allows the BK/HHC-R to serve applications originally designed for the 0FHA0075Z without modification.

Frequently Asked Questions (FAQ)

Q: Can the BK/HHC-R directly replace the 0FHA0075Z in existing applications?

A: Yes. Both components share identical mechanical dimensions (0.75" L x 0.2" W), voltage rating (32V), fuse type (blade), circuit configuration (1 circuit), mounting method (free hanging in-line), and termination style (wire leads). Physical installation and electrical integration are identical.

Q: Why does the BK/HHC-R have a higher current rating (16 A) than the 0FHA0075Z (7.5 A)?

A: The current rating refers to the maximum capacity of the fuse holder itself. The actual circuit protection level is determined by the fuse element installed in the holder. A 7.5 A fuse can be installed in the BK/HHC-R holder without any functional difference from the original configuration.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant. The BK/HHC-R carries additional REACH Unaffected status. No compliance barriers exist for substitution.

Q: What fuse types are compatible with both holders?

A: Both the 0FHA0075Z and BK/HHC-R are designed for ATC and ATO blade fuses with dimensions of 0.75" L x 0.2" W (19.1mm x 5.1mm).

Q: Is the BK/HHC-R available in different packaging options?

A: The BK/HHC-R is supplied in bulk packaging. Verify packaging requirements for your procurement process.
