Littelfuse 0217010.H Glass Cartridge Fuse 10A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0217010.H is a 10A 250VAC fast-blow glass cartridge fuse in 5x20mm form factor, designed for circuit protection in AC and DC applications. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications. Substitute parts must preserve the 10A current rating, 250V AC voltage rating, fast-blow response time, and 5x20mm physical dimensions to ensure direct functional replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: current rating (10A), voltage rating (250V AC), fuse type (cartridge glass), response time (fast blow), physical dimensions (5x20mm), and breaking capacity (100A). All substitute parts listed maintain these specifications without deviation. Littelfuse Series 217 and 617 variants are grouped as parametric equivalents from the original manufacturer. Eaton GDB and S500 series parts are manufacturer-recommended alternatives meeting identical electrical and mechanical requirements. Packaging format (bulk vs. tape) does not affect electrical equivalence.

Engineering Selection Recommendations

All listed substitute parts are active production items with ROHS3 compliance, addressing the obsolete status and non-compliance of the original 0217010.H. Littelfuse Series 217 variants (0217010.HXP, 0217010.MXBP, 0217010.MXP, 0217010.TXP, 0217010.VXP) provide direct manufacturer continuity with identical electrical characteristics and enhanced regulatory compliance. The Littelfuse Series 617 variant (0617010.MXP) maintains full parametric equivalence with alternative certification coverage (CE, UR, VDE vs. CE, K-MARK, PSE, VDE). Eaton GDB and S500 series alternatives (BK/GDB-10A, BK/S500-10-R, BK1/S500-10-R, GDB-10A) are manufacturer-recommended cross-references with established UL and international certifications. Selection between Littelfuse and Eaton alternatives depends on existing supply chain qualification and certification requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can 0217010.HXP directly replace 0217010.H without circuit modification?

A: Yes. Both parts share identical current rating (10A), voltage rating (250V AC), response time (fast blow), physical dimensions (5x20mm), and breaking capacity (100A). The HXP variant is the active production equivalent with improved RoHS3 compliance.

Q: What is the difference between Littelfuse Series 217 and Series 617 variants?

A: Series 217 and 617 variants maintain identical electrical and mechanical specifications for this 10A 250V application. The series designation reflects internal design architecture and certification scope. Series 617 carries UR certification in place of K-MARK, providing alternative regulatory coverage for specific markets.

Q: Are Eaton GDB and S500 series fuses electrically equivalent to Littelfuse parts?

A: Yes. Eaton GDB-10A and S500-10-R variants match all critical parameters: 10A current, 250V AC voltage, fast-blow response, 5x20mm form factor, and 100A breaking capacity. These are manufacturer-recommended alternatives with UL and international certifications.

Q: Does packaging format (bulk vs. tape) affect electrical performance?

A: No. Packaging format is a supply and handling specification only. Bulk and tape-packaged variants of the same part number are electrically and mechanically identical.

Q: Which substitute part offers the best compliance for new designs?

A: All active substitute parts listed carry ROHS3 compliance. Selection should be based on existing certification requirements and supply chain qualification. Littelfuse Series 217 variants provide direct manufacturer continuity; Eaton alternatives provide established UL certification pathways.

Q: Can I mix different substitute part numbers in the same circuit?

A: Yes, provided all parts meet the circuit's electrical requirements. All listed substitutes are parametrically equivalent for 10A 250V AC fast-blow applications. However, maintain consistency within a single assembly for traceability and supply chain management.
