Littelfuse 0217008.H Glass Cartridge Fuse 8A 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0217008.H is an 8A 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 8A 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: 8 A (exact match required)
Voltage Rating: 250 V AC (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Fast Blow (exact match required)
Physical Dimensions: 5mm x 20mm (exact match required)
Breaking Capacity: 80A (exact match required)
Mounting Type: Requires Holder (exact match required)

All substitute parts listed below meet these criteria. Secondary parameters including DC cold resistance, melting I²t, and RoHS compliance status are provided for engineering evaluation but do not disqualify substitution eligibility when primary parameters align.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the 0217008.H. Selection among active alternatives should be based on the following factors:

Littelfuse Series 217 variants (0217008.HXP, 0217008.MXBP, 0217008.MXP, 0217008.TXP, 0217008.VXP): These parts maintain the original manufacturer lineage and are ROHS3 compliant. The 217 series variants offer the broadest approval agency coverage including BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE certifications. DC cold resistance values are marginally lower (0.0068Ω vs 0.007Ω), representing negligible operational difference.

Littelfuse Series 617 variant (0617008.MXP): This part provides equivalent electrical performance with reduced approval agency scope (CE, UR, VDE only). Selection is appropriate where application requirements align with these specific certifications.

Eaton GDB and S500 series (BK/GDB-8A, BK/S500-8-R, BK1/S500-8-R, GDB-8A): These alternatives are active and RoHS compliant. DC cold resistance is slightly elevated (0.01Ω), which remains within acceptable tolerance for 8A cartridge fuse applications. Eaton parts carry UL, VDE, BSI, CSA, and cULus certifications depending on variant.

For applications requiring maximum certification coverage and RoHS3 compliance, Littelfuse 217 series variants are preferred. For applications with specific regional certification requirements, cross-reference the approval agency list against application standards.

Frequently Asked Questions (FAQ)

Q: Can 0217008.H be directly replaced with any of the listed substitutes?

A: Yes. All listed parts are direct functional equivalents meeting identical electrical specifications (8A, 250V, fast-blow, 5x20mm). Physical installation is identical as all parts require the same holder type.

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

A: Both series meet the core electrical and mechanical requirements. The 617 series (0617008.MXP) carries a narrower set of approval certifications (CE, UR, VDE) compared to the 217 series variants (BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, VDE). Selection depends on application certification requirements.

Q: Why do DC cold resistance values differ between manufacturers?

A: DC cold resistance variation (0.007Ω to 0.01Ω) reflects manufacturing tolerances and design approaches across manufacturers. These differences are negligible for 8A cartridge fuse applications and do not affect substitution eligibility or circuit protection performance.

Q: Is RoHS compliance a substitution requirement?

A: RoHS compliance is not a substitution requirement based on electrical or mechanical parameters. However, for new designs or applications subject to RoHS regulations, ROHS3-compliant variants (all Littelfuse and Eaton S500 series parts listed) are available.

Q: Can I use Eaton parts as direct replacements for Littelfuse?

A: Yes. Eaton GDB and S500 series parts meet all electrical and mechanical equivalence criteria. Certification differences should be evaluated against application standards. Both manufacturers' parts are mechanically and electrically interchangeable.

Q: What holder type is required for these fuses?

A: All listed parts require a standard 5x20mm cartridge fuse holder. No special holder modifications are necessary when substituting between any of these parts.
