Substitute Part Grouping Explanation

The Littelfuse 01070002Z qualifies as a direct substitute for the 01070001Z based on matching electrical and mechanical parameters. Both parts share identical specifications across all critical substitution criteria: 30 A current rating, 250V voltage rating, 0.563" diameter cartridge fuse compatibility, single-circuit configuration, chassis mount orientation, and solder lug termination. The primary distinction is product status and contact finish specification, with 01070002Z representing the active production equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 01070002Z is the manufacturer-recommended substitute for the obsolete 01070001Z. Both parts maintain ROHS3 compliance and identical electrical specifications. The transition from tin to nickel contact finish in the substitute part does not affect functional compatibility with standard 9/16" diameter cartridge fuses. Selection of 01070002Z is appropriate for new designs and replacement applications where active product availability is required. The active product status of 01070002Z ensures ongoing supply chain support and manufacturing consistency.

Frequently Asked Questions (FAQ)

Q: Can 01070002Z directly replace 01070001Z in existing assemblies? A: Yes. Both parts share identical electrical ratings (30 A, 250V), mechanical dimensions (0.563" fuse diameter), mounting configuration (chassis mount), and termination style (solder lug). The contact finish difference (tin vs. nickel) does not affect functional substitution.

Q: What is the significance of the contact finish change from tin to nickel? A: Contact finish affects corrosion resistance and long-term reliability characteristics. Nickel finish provides enhanced corrosion resistance compared to tin, making it suitable for applications with extended service life or exposure to corrosive environments.

Q: Are both parts compatible with 9/16" diameter fuses? A: Yes. Both the 01070001Z and 01070002Z are designed for use with 9/16" diameter cartridge fuses, as specified in the "For Use With/Related Products" parameter.

Q: Why is 01070001Z classified as obsolete? A: Obsolete status indicates the part is no longer in active production. The 01070002Z represents the current production equivalent and should be used for new procurement.

Q: Do both parts meet the same regulatory compliance standards? A: Yes. Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications.
