Littelfuse 0235.200VXP Glass Cartridge Fuse 200mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0235.200VXP is an active-status glass cartridge fuse rated for 200mA at 250VAC, housed in a 5x20mm form factor. This fast-blow fuse requires a compatible holder for installation and is designed for overcurrent protection in AC/DC circuits. Substitute parts are identified when they maintain identical electrical ratings, mechanical dimensions, response characteristics, and mounting requirements while meeting equivalent safety certifications.

Substitute Part Grouping Explanation

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

Current Rating: 200 mA (exact match required)
Voltage Rating (AC): 250 V (exact match required)
Package / Case: 5mm x 20mm (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Fast Blow (exact match required)
Mounting Type: Requires Holder (exact match required)
Breaking Capacity @ Rated Voltage: 35A (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria. Variations in DC Cold Resistance, Melting I²t, and approval agency certifications do not disqualify substitution when all primary electrical and mechanical parameters are identical.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and are ROHS3 compliant. Selection between Littelfuse 0235.200VXP and its equivalents should be based on:

Littelfuse Series 235 (0235.200VXP, 0235.200HXP): Approved by CE, CSA, K-MARK, and UL. Suitable for applications requiring these specific certifications.

Littelfuse Series 217 (0217.200HXP, 0217.200MXP, 0217.200TXP): Approved by CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. Offers broader certification coverage including CCC and SEMKO. The 0217.200TXP variant includes KC and UR approvals.

SCHURTER 0034.1509 (FSF 5x20 Series): Approved by CCC, cURus, and VDE. Suitable for applications requiring CCC certification.

OptiFuse FSD-200MA: Approved by cURus and IEC 60127. Suitable for applications requiring IEC 60127 compliance.

All parts are electrically and mechanically interchangeable within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Littelfuse 0235.200VXP with any of the listed parts?

A: Yes. All listed parts are parametric equivalents meeting identical electrical ratings (200mA, 250VAC), mechanical dimensions (5x20mm), response characteristics (fast-blow), and mounting requirements (requires holder). Selection should be based on required safety certifications for your application.

Q: What is the difference between the Littelfuse Series 235 and Series 217 fuses?

A: Both series maintain identical electrical and mechanical specifications for the 200mA 250VAC 5x20mm rating. Series 217 parts carry additional certifications (CCC, SEMKO) compared to Series 235. DC Cold Resistance and Melting I²t values differ slightly but do not affect substitution eligibility.

Q: Are cross-manufacturer substitutions (Littelfuse, SCHURTER, OptiFuse) acceptable?

A: Yes. The SCHURTER 0034.1509 and OptiFuse FSD-200MA maintain all critical electrical and mechanical parameters. Verify that the required safety certifications for your application are present on the selected substitute.

Q: Does the difference in Melting I²t between parts affect compatibility?

A: No. Melting I²t variations (ranging from 0.00867 to 0.0256 across the listed parts) do not disqualify substitution when all primary electrical ratings, mechanical dimensions, and response characteristics are identical.

Q: What certifications should I verify before selecting a substitute?

A: Verify that the substitute part carries the safety certifications required by your application and regional standards. Littelfuse Series 217 parts offer the broadest certification coverage (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE). Littelfuse Series 235 parts are certified by CE, CSA, K-MARK, and UL.

Q: Can I use these fuses in any 5x20mm holder?

A: Yes. All listed parts require a compatible 5x20mm fuse holder. Verify holder compatibility with your equipment specifications.
