Parameter Comparison

Engineering Selection Recommendations

Both the 0895040.Z and 0895040.U are active products manufactured by Littelfuse Inc. with full ROHS3 compliance and identical electrical specifications. Selection between these parts is based on inventory availability and procurement logistics rather than technical performance differentiation. The 0895040.Z maintains UL approval certification, while the 0895040.U does not list approval agency designation in available documentation. For applications requiring explicit UL certification documentation, the 0895040.Z is the specified choice. Both parts are suitable for automotive 40A, 58V DC circuit protection applications utilizing Auto Link holders.

Frequently Asked Questions (FAQ)
