Littelfuse 0218.080H Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218.080H is an 80 mA, 250 V AC/DC slow-blow glass cartridge fuse in a 5mm x 20mm package format. This component is classified as obsolete, requiring identification of active equivalent alternatives for new designs and ongoing maintenance applications. Equivalent and substitute parts maintain the same electrical ratings, mechanical dimensions, and functional performance while offering current product availability and updated compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (80 mA), voltage rating (250 V AC), response time (slow blow), package dimensions (5mm x 20mm), fuse type (cartridge glass), and breaking capacity (35A). Parts are grouped into three categories:

Parametric Equivalents (Littelfuse Series 218): Parts 0218.080HXP, 0218.080MXBP, 0218.080MXP, 0218.080TXP, and 0218.080VXP maintain identical electrical and mechanical specifications with active product status and RoHS3 compliance.

Parametric Equivalent (Littelfuse Series 239): Part 0239.080MXP meets all core electrical and mechanical requirements with active status and RoHS3 compliance.

Direct Manufacturer Alternatives: Parts from Eaton (BK/GDC-80MA, BK/S506-80-R), Bel Fuse (5ST 80-R), and SCHURTER (0034.5606.22) provide equivalent functionality from alternative manufacturers with active product status.

Engineering Selection Recommendations

For applications requiring direct Littelfuse 218 series continuity, 0218.080HXP, 0218.080MXBP, 0218.080MXP, 0218.080TXP, and 0218.080VXP are active alternatives with RoHS3 compliance and expanded certification coverage including CCC, CE, CSA, K-MARK, KC, SEMKO, and VDE approvals.

For applications permitting manufacturer substitution, Eaton BK/GDC-80MA and BK/S506-80-R provide active alternatives with cULus and IMQ certifications. Bel Fuse 5ST 80-R offers the broadest approval agency coverage including CCC, CE, CSA, cURus, IMQ, SEMKO, and VDE. SCHURTER 0034.5606.22 is available in Tape & Reel packaging for automated assembly environments.

All listed substitutes maintain identical electrical performance and mechanical compatibility with the original 0218.080H specification.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 0218.080H with any of the listed substitutes? A: Yes. All listed parts maintain identical current rating (80 mA), voltage rating (250 V AC), response time (slow blow), package dimensions (5mm x 20mm), and breaking capacity (35A). Direct mechanical and electrical substitution is supported.

Q: What is the difference between Littelfuse 218 series variants (HXP, MXBP, MXP, TXP, VXP)? A: All variants meet the core electrical and mechanical requirements. Differences exist in DC cold resistance and melting I²t values, which do not affect standard circuit protection performance. Selection may depend on specific application thermal characteristics and packaging requirements (bulk vs. tape & reel).

Q: Why is 0218.080H marked as obsolete? A: The original part has been superseded by active alternatives offering improved compliance certifications (RoHS3) and expanded approval agency coverage. Active equivalents provide equivalent performance with current manufacturing support.

Q: Can I use parts from different manufacturers interchangeably? A: Yes, provided all electrical and mechanical parameters match. Eaton, Bel Fuse, and SCHURTER alternatives meet identical specifications. Verify holder compatibility and approval agency requirements for your specific application.

Q: What packaging options are available? A: Most substitutes are supplied in bulk packaging. SCHURTER 0034.5606.22 is available in Tape & Reel format for automated assembly processes.

Q: Are all substitutes RoHS compliant? A: Yes. All active substitutes carry RoHS3 or RoHS compliance certification. The original 0218.080H is RoHS non-compliant.
