Littelfuse 0217.063H Glass Cartridge Fuse 63mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0217.063H is a 63mA 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 63mA current rating, 250V voltage rating, fast-blow response characteristic, 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: 63 mA (exact match required)
Voltage Rating: 250 V AC (exact match required)
Response Time: Fast Blow (exact match required)
Physical Package: 5mm x 20mm (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Mounting Configuration: Requires Holder (exact match required)
Breaking Capacity: 35A (exact match required)

All substitute parts listed below meet these criteria. Variations in DC cold resistance, melting I²t values, and RoHS compliance status do not affect functional substitutability for the specified electrical circuit protection application.

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the 0217.063H based on identical electrical ratings and mechanical specifications. Selection among active alternatives should prioritize:

Littelfuse Series 217 variants (0217.063HXP, 0217.063MXBP, 0217.063MXP, 0217.063TXP, 0217.063VXP): These parts maintain manufacturer continuity with the original 0217.063H and carry ROHS3 compliance certification. The 0217.063MXP variant has the highest inventory availability (4632 units).

Eaton Electronics Division alternatives (BK/GDB-63MA, BK/GMA-63-R, BK/S500-63-R, BK1/GMA-63-R): These cross-manufacturer substitutes provide equivalent electrical performance and active product status with RoHS or ROHS3 compliance. Eaton GMA series parts carry CSA, PSE, and UL certifications.

SCHURTER 0034.1530.PT: This alternative offers through-hole mounting configuration with ROHS3 compliance and cURus certification, suitable for applications requiring axial lead orientation.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 0217.063H with any of the listed substitutes?

A: Yes. All listed parts meet the critical substitution parameters: 63mA current rating, 250V AC voltage rating, fast-blow response, 5x20mm physical dimensions, and 35A breaking capacity. Direct socket compatibility is maintained for holder-based mounting configurations.

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

A: The 0217.063H, 0217.063HXP, 0217.063MXBP, 0217.063MXP, 0217.063TXP, and 0217.063VXP are electrically and mechanically identical. Differences exist only in packaging format (tape/reel variants) and RoHS compliance status. The original 0217.063H is obsolete; active alternatives are recommended.

Q: Does DC cold resistance variation affect substitutability?

A: No. DC cold resistance values (ranging from 10.45 to 125 Ohms across the listed parts) do not affect circuit protection performance for the specified AC/DC fuse application. Substitution remains valid regardless of this parameter variation.

Q: Are there mounting differences between Littelfuse and Eaton alternatives?

A: Littelfuse Series 217 and Eaton GDB/GMA/S500 series all require external fuse holders for 5x20mm cartridges. SCHURTER 0034.1530.PT provides through-hole axial lead mounting as an alternative configuration. Verify holder compatibility before selection.

Q: Which substitute has the best compliance certifications?

A: Littelfuse Series 217 variants carry CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE approvals. Eaton GMA series carries CSA, PSE, and UL certifications. SCHURTER 0034.1530.PT carries cURus certification. Selection should align with your application's regulatory requirements.

Q: Is the SCHURTER 0034.1530.PT a direct replacement?

A: The SCHURTER part is electrically equivalent but differs in mounting type (through-hole axial vs. cartridge requiring holder) and physical dimensions (5.40mm x 22.50mm vs. 5.20mm x 20.00mm). Use only if your circuit board design accommodates axial lead mounting.
