Littelfuse 0235.200H Equivalent & Substitute Parts

Part Overview

The Littelfuse 0235.200H is a 200 mA, 250 V AC/DC fast-blow glass cartridge fuse in 5mm x 20mm form factor, designed for circuits requiring holder-mounted protection. This part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for direct circuit substitution.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (200 mA), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast blow), physical dimensions (5mm x 20mm), and mounting requirement (holder-mounted). All identified substitutes maintain these core electrical and mechanical specifications.

Littelfuse Series 217 and 235 variants meet these criteria and are classified as active products. Eaton GDB and GMA series alternatives also satisfy the parametric requirements. Substitutes differ in secondary characteristics such as melting I²t values, DC cold resistance, and regulatory certifications, which do not affect functional interchangeability within the specified electrical parameters.

Engineering Selection Recommendations

For direct replacement of the obsolete 0235.200H, the Littelfuse 0235.200HXP, 0235.200MXP, and 0235.200VXP are functionally equivalent within the same series, maintaining identical DC cold resistance (3.15 Ω) and comparable melting I²t characteristics. These parts are active products with ROHS3 compliance and expanded regulatory certifications (CE, CSA, KC, UL).

Littelfuse Series 217 variants (0217.200HXP, 0217.200MXBP, 0217.200MXP, 0217.200TXP, 0217.200VXP) provide parametric equivalence with lower DC cold resistance (1.7 Ω) and higher melting I²t values (0.02). These parts carry broader approval agency certifications including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE.

Eaton alternatives BK/GDB-200MA and BK/GMA-200-R satisfy all core electrical and mechanical parameters. The BK/GMA-200-R exhibits the lowest melting I²t (0.001) and intermediate DC cold resistance (2.5 Ω), while BK/GDB-200MA provides higher DC cold resistance (6.8 Ω) with UL and VDE certifications.

Selection should prioritize active products with current regulatory compliance. Series 235 variants preserve original resistance characteristics; Series 217 variants offer enhanced certifications; Eaton alternatives provide cross-manufacturer options with distinct thermal response profiles.

Frequently Asked Questions (FAQ)

Q: Can Series 217 fuses replace Series 235 fuses in the same circuit? A: Yes. Both series maintain identical current rating (200 mA), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast blow), and physical dimensions (5mm x 20mm). Differences in melting I²t and DC cold resistance do not affect functional interchangeability for circuits designed to these electrical specifications.

Q: What is the significance of melting I²t variation among substitutes? A: Melting I²t defines the thermal energy required to melt the fuse element. Variations (0.001 to 0.02) reflect different fuse element designs but do not alter the 200 mA current rating or 250 V voltage rating. Circuit protection performance remains consistent across all listed substitutes.

Q: Are Eaton GDB and GMA series fuses compatible with Littelfuse holder fixtures? A: Yes. All substitutes maintain the 5mm x 20mm cartridge form factor and holder-mounted design, ensuring mechanical compatibility with existing fuse holders designed for this standard dimension.

Q: Which substitute offers the best regulatory coverage? A: Littelfuse Series 217 variants carry the broadest certification portfolio, including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. These certifications support global market applications.

Q: Is RoHS compliance a factor in substitution? A: The original 0235.200H is RoHS non-compliant. All active substitutes are RoHS3 compliant or RoHS compliant, meeting current environmental regulations. This represents an improvement over the obsolete part.

Q: Can I use BK/GMA-200-R as a direct replacement for 0235.200H? A: Yes. The BK/GMA-200-R meets all parametric requirements: 200 mA current rating, 250 V voltage rating, fast-blow response, 5mm x 20mm dimensions, and holder-mounted design. The lower melting I²t (0.001) reflects a faster thermal response but maintains rated current protection.
