Littelfuse 01020076H Fuse Clip Cartridge 250V 15A PCB

Part Overview

The Littelfuse 01020076H is a cartridge fuse clip designed for 250V, 15A applications with through-hole PCB mounting. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The fuse clip accommodates 1/4" diameter cartridge fuses and features horizontal orientation with PC pin termination suitable for standard PCB assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 01020076H is determined by the following critical parameters: voltage rating, current rating, fuse size, mounting type, orientation, termination style, and circuit count. Parts meeting all these specifications are considered direct equivalents. Parts with differing voltage or current ratings are listed as functional alternatives where application requirements permit.

The 01020076Z represents a direct equivalent with identical electrical and mechanical specifications, differing only in product status (active versus obsolete) and packaging format. The 10207101009 is a functional alternative with modified voltage and current ratings suitable for applications requiring higher voltage tolerance at reduced current capacity. The 3529 from Eaton - Bussmann Electrical Division is listed as a cross-reference but lacks sufficient parameter documentation for full compatibility assessment.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the obsolete 01020076H, the 01020076Z is the primary selection. Both parts maintain identical electrical ratings (250V, 15A), mechanical configuration, and RoHS3 compliance. The 01020076Z is currently in active production status with higher inventory availability, making it suitable for new designs and production continuity.

The 10207101009 serves as a functional alternative where circuit design permits operation at 500V with 10A current capacity. This part maintains mechanical compatibility through identical fuse size, mounting type, and termination style. Selection of this alternative requires verification that the application does not exceed the reduced 10A current rating and can accommodate the elevated 500V voltage specification.

The 3529 from Eaton - Bussmann Electrical Division is referenced as a cross-manufacturer option but lacks sufficient documented parameters for direct compatibility confirmation. Evaluation of this part requires additional technical documentation from the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the 01020076Z be used as a direct replacement for the 01020076H?

A: Yes. The 01020076Z is a direct equivalent with identical voltage (250V), current (15A), fuse size (0.25" diameter), mounting type (through hole), orientation (horizontal), termination style (PC pin), and circuit count (1). The primary difference is product status; the 01020076Z is active production while the 01020076H is obsolete.

Q: What are the limitations of using the 10207101009 as a substitute?

A: The 10207101009 has a reduced current rating of 10A compared to the 15A specification of the 01020076H, and an elevated voltage rating of 500V versus 250V. This part is suitable only for applications where the circuit design operates within these modified parameters. The mechanical interface remains compatible.

Q: Are all substitute parts RoHS3 compliant?

A: The 01020076Z and 10207101009 are both ROHS3 compliant. Compliance status for the 3529 is not documented in available specifications.

Q: What packaging options are available for these parts?

A: The 01020076H was supplied in standard packaging (format not specified). The 01020076Z is available in bulk packaging. The 10207101009 is available in bulk packaging. Packaging format for the 3529 is not specified.

Q: Can the 3529 be used as a substitute?

A: The 3529 is listed as a cross-reference but lacks sufficient technical documentation to confirm compatibility. Voltage rating, current rating, fuse size, and other critical parameters are not specified. Direct compatibility cannot be established without additional manufacturer documentation.
