Equivalent & Substitute Parts for Littelfuse 0FHA0015Z Fuse Holder

Part Overview

The Littelfuse 0FHA0015Z is a blade fuse holder rated for 15A at 32V, designed for inline mounting with wire lead termination. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component procurement. The FHA series holder accommodates standard ATC/ATO blade fuses in a free-hanging configuration suitable for automotive and industrial applications requiring reliable fuse protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0FHA0015Z is determined by the following critical parameters:

• Voltage Rating: Must be 32V or higher to ensure safe operation
• Fuse Size: Must accommodate 0.75" L x 0.2" W (19.1mm x 5.1mm) blade fuses
• Fuse Type: Must support ATC/ATO blade fuses
• Mounting Configuration: Must provide free-hanging (in-line) mounting with wire lead termination
• Number of Circuits: Must be single-circuit design
• Current Rating: Must be rated for the circuit's maximum current requirement

The Eaton Bussmann BK/HHC-R qualifies as a direct substitute based on matching voltage, fuse size, fuse type, mounting style, circuit count, and termination configuration. The current rating difference (16A vs. 15A) represents an uprated alternative suitable for circuits requiring the original 15A protection or lower.

Parameter Comparison

Engineering Selection Recommendations

The Eaton Bussmann BK/HHC-R is the qualified substitute for the obsolete Littelfuse 0FHA0015Z. Both components maintain identical mechanical and electrical compatibility across all critical parameters: voltage rating, fuse size, blade type, mounting configuration, and termination style.

The BK/HHC-R offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts maintain ROHS3 compliance, supporting regulatory requirements for electronic component procurement.

The 16A current rating of the BK/HHC-R accommodates circuits originally protected by the 15A 0FHA0015Z. When selecting the substitute, verify that the circuit's maximum current requirement does not exceed 16A to maintain appropriate protection levels.

Frequently Asked Questions (FAQ)

Q: Can the Eaton Bussmann BK/HHC-R directly replace the Littelfuse 0FHA0015Z?

A: Yes. Both components share identical voltage rating (32V), fuse size (0.75" L x 0.2" W), blade type (ATC/ATO), mounting configuration (free-hanging in-line), circuit count (1), and termination style (wire leads). Physical and electrical compatibility is confirmed.

Q: What is the significance of the current rating difference (15A vs. 16A)?

A: The BK/HHC-R is rated for 16A, which is higher than the original 15A rating. This uprated specification is suitable for circuits requiring 15A protection or lower. Verify that your circuit's maximum current does not exceed 16A before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the Littelfuse 0FHA0015Z and Eaton Bussmann BK/HHC-R are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: Why is the original part listed as obsolete?

A: The Littelfuse 0FHA0015Z has reached end-of-life status. The Eaton Bussmann BK/HHC-R maintains active product status, providing a reliable long-term alternative for new designs and component replacement.

Q: Are there any packaging differences between these parts?

A: The original part is available in standard packaging, while the BK/HHC-R is supplied in bulk packaging. Verify packaging requirements for your procurement process.
