Littelfuse 01110501N Fuse Clip Cartridge 250V 10A PCB - Equivalent & Substitute Parts

Part Overview

The Littelfuse 01110501N is a cartridge fuse clip designed for 5mm diameter fuses with a 10A current rating at 250V. This component functions as a through-hole mounted fuseholder for PCB applications, utilizing spring brass contacts with tin finish. The 01110501N is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The substitute part 01110501Z provides functional continuity with identical electrical and mechanical specifications while maintaining active product status.

Substitute Part Grouping Explanation

The Littelfuse 01110501Z qualifies as a direct substitute for the 01110501N based on identical alignment across all critical electrical and mechanical parameters. Substitution eligibility is determined by the following parameters:

• Current Rating: 10 A (identical)
• Voltage Rating: 250V (identical)
• Fuse Size: 0.197" Dia (5mm) (identical)
• Fuse Type: Cartridge (identical)
• Mounting Type: Through Hole (identical)
• Orientation: Horizontal (identical)
• Number of Circuits: 1 (identical)
• Termination Style: PC Pin (identical)
• Contact Material: Spring Brass (identical)
• Contact Finish: Tin (identical)
• Series: 111 (identical)

The 01110501Z maintains full functional and physical compatibility with the 01110501N, differing only in packaging configuration and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The 01110501Z is the appropriate selection for applications currently specified with the 01110501N. Both parts maintain ROHS3 compliance and identical electrical performance characteristics. The 01110501Z carries active product status, ensuring long-term availability and supply chain continuity. The transition from the obsolete 01110501N to the 01110501Z presents no functional or compliance trade-offs, as all critical parameters remain constant. Bulk packaging of the 01110501Z accommodates both production and maintenance inventory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 01110501Z directly replace the 01110501N in existing PCB designs?
