Littelfuse 0217.200H Glass Cartridge Fuse 200mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0217.200H is a 200mA fast-blow glass cartridge fuse rated for 250V AC/DC operation in a 5x20mm form factor. This part is classified as obsolete, requiring identification of active equivalent alternatives for new designs and ongoing production support. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and holder compatibility while meeting current RoHS and regulatory compliance standards.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Current Rating: 200 mA (exact match required)
Voltage Rating: 250 V AC (exact match required)
Response Time: Fast Blow (exact match required)
Package Dimensions: 5mm x 20mm (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Breaking Capacity: 35A (exact match required)

Substitute parts are grouped into two categories:

Category 1: Littelfuse Series 217 & 235 (Parametric Equivalents) Parts 0217.200HXP, 0217.200MXBP, 0217.200MXP, 0217.200TXP, 0217.200VXP, 0235.200HXP, 0235.200MXP, and 0235.200VXP meet all electrical and mechanical requirements. Series 217 parts are direct functional replacements with active product status and ROHS3 compliance. Series 235 parts share identical electrical ratings but exhibit different melting I²t and DC cold resistance characteristics due to internal construction differences; both series maintain 35A breaking capacity and full dimensional compatibility.

Category 2: Eaton GDB & GMA Series (Direct Manufacturer Alternatives) Parts BK/GDB-200MA and BK/GMA-200-R provide cross-manufacturer equivalence with identical electrical specifications and 5x20mm form factor. These parts are manufactured by Eaton - Electronics Division and maintain full holder compatibility.

Engineering Selection Recommendations

Primary Recommendation: Littelfuse Series 217 Active Variants

For direct replacement of the obsolete 0217.200H, select from the active Littelfuse Series 217 parts: 0217.200HXP, 0217.200MXBP, 0217.200MXP, 0217.200TXP, or 0217.200VXP. These parts maintain identical DC cold resistance (1.7Ω), melting I²t (0.02), and all electrical specifications. All variants carry ROHS3 compliance and active product status with full regulatory certifications (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE). Packaging options include bulk availability with inventory levels ranging from 716 to 1779 pieces.

Secondary Recommendation: Littelfuse Series 235 Variants

Series 235 parts (0235.200HXP, 0235.200MXP, 0235.200VXP) provide functional equivalence with identical current, voltage, and breaking capacity ratings. These parts exhibit lower melting I²t (0.00867 vs. 0.02) and higher DC cold resistance (3.15Ω vs. 1.7Ω) due to different internal element construction. Series 235 parts are suitable for applications where faster thermal response is acceptable. Regulatory certifications are limited to CE, CSA, KC, and UL (no CCC, K-MARK, or SEMKO).

Cross-Manufacturer Alternative: Eaton GDB & GMA Series

Eaton BK/GDB-200MA and BK/GMA-200-R provide equivalent electrical and mechanical specifications with full holder compatibility. BK/GMA-200-R exhibits the lowest melting I²t (0.001) and is recommended where ultra-fast response characteristics are required. Both Eaton parts carry active status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can I use Series 235 parts as a direct replacement for Series 217?

A: Series 235 parts meet all electrical and mechanical requirements for holder compatibility and circuit protection function. However, they exhibit different melting I²t and DC cold resistance values. Applications sensitive to thermal response characteristics should be evaluated before substitution.

Q: What is the difference between the various Littelfuse Series 217 part numbers (HXP, MXBP, MXP, TXP, VXP)?

A: All Series 217 variants share identical electrical specifications, current ratings, voltage ratings, and response times. Differences are limited to packaging configuration and internal manufacturing variants. All are functionally equivalent for circuit protection applications.

Q: Are Eaton GDB and GMA series parts fully compatible with Littelfuse holders?

A: Yes. Both Eaton series maintain the 5x20mm form factor and are designed for standard cartridge fuse holders. Mechanical and electrical compatibility is confirmed across all specified parameters.

Q: Why does the original 0217.200H show RoHS non-compliance?

A: The 0217.200H is classified as obsolete. Active replacement parts (Series 217 and 235) are ROHS3 compliant, meeting current environmental and regulatory standards.

Q: What is the significance of melting I²t differences between Series 217 and Series 235?

A: Melting I²t defines the thermal energy required to melt the fuse element. Lower values (Series 235: 0.00867) indicate faster thermal response to overcurrent conditions. Higher values (Series 217: 0.02) provide slightly slower response. Both maintain the same 200mA current rating and 35A breaking capacity.

Q: Can I mix different Littelfuse Series 217 variants in the same circuit?

A: Yes. All Series 217 variants (HXP, MXBP, MXP, TXP, VXP) are electrically and mechanically identical and can be used interchangeably within the same application.
