Equivalent & Substitute Parts for 0MAH0001Z

Part Overview

The 0MAH0001Z is a fuse holder manufactured by Littelfuse Inc., designed for blade-type fuses with a 60 A current rating. This component is classified as obsolete, indicating that direct replacement with the original part number may not be available through standard distribution channels. The MAH series fuse holder is configured for free-hanging (in-line) mounting with wire lead termination, suitable for use with Maxi (ATX) fuse types. Identifying equivalent substitute parts is necessary to maintain circuit protection functionality in applications where the original component is no longer procurable.

Substitute Part Grouping Explanation

Substitution of the 0MAH0001Z is determined by the following critical parameters that must remain consistent:

• Fuse Size: 1.161" L x 0.374" W (29.5mm x 9.5mm) — physical dimensions must match to ensure proper fuse insertion and retention
• Fuse Type: Blade configuration — electrical and mechanical interface standard
• Mounting Type: Free Hanging (In-Line) — installation method and form factor
• Termination Style: Wire Leads — connection interface to the circuit
• Number of Circuits: 1 — single-circuit configuration
• For Use With: Maxi (ATX) — fuse compatibility standard

The substitute part BK/HHX from Eaton - Bussmann Electrical Division meets these core requirements. However, the current rating differs: the original part is rated for 60 A, while the substitute is rated for 48 A at 32V. This difference in current rating represents a functional change and must be evaluated against the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The BK/HHX from Eaton - Bussmann Electrical Division is the designated manufacturer-recommended substitute for the obsolete 0MAH0001Z. Both components share identical physical dimensions, fuse type, mounting configuration, and termination style, ensuring mechanical and electrical interface compatibility within the Maxi (ATX) fuse system.

Both parts maintain ROHS3 compliance, satisfying environmental and regulatory requirements. The BK/HHX carries active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete 0MAH0001Z.

The primary consideration is the current rating differential: the substitute operates at 48 A versus the original 60 A specification. This lower current rating must be evaluated against the circuit protection requirements of the target application. If the application circuit requires 60 A protection, the BK/HHX may not provide equivalent protection levels. Conversely, if the application can operate within a 48 A protection envelope, the substitute provides a direct form-fit-function replacement.

Frequently Asked Questions (FAQ)

Q: Can the BK/HHX directly replace the 0MAH0001Z in all applications?

A: The BK/HHX matches the 0MAH0001Z in physical dimensions, fuse type, mounting method, and termination style. However, the current rating differs (48 A versus 60 A). Substitution is valid only if the application circuit protection requirements are compatible with the 48 A rating.

Q: What are the key physical compatibility factors?

A: The fuse size (1.161" L x 0.374" W / 29.5mm x 9.5mm), blade fuse type, free-hanging in-line mounting, and wire lead termination must remain consistent. Both the original and substitute parts meet these specifications.

Q: Does the BK/HHX have a voltage rating specification?

A: Yes, the BK/HHX is rated for 32V operation. The original 0MAH0001Z does not specify a voltage rating in the available documentation. Verify that the application voltage does not exceed 32V when using the substitute.

Q: Are both parts RoHS compliant?

A: Yes, both the 0MAH0001Z and BK/HHX are ROHS3 compliant, meeting environmental and regulatory standards for electronic component manufacturing.

Q: Why is the original part obsolete?

A: The 0MAH0001Z is classified as obsolete, meaning Littelfuse Inc. has discontinued production. The BK/HHX from Eaton - Bussmann maintains active product status and represents the current equivalent offering in the market.
