Substitute Part Grouping Explanation

Substitute parts for the 0217.200VXP are classified based on strict electrical and mechanical parameter alignment:

Parametric Equivalents (Littelfuse Series 217 & 235): Parts 0217.200HXP, 0217.200MXP, and 0217.200TXP maintain identical current rating (200mA), voltage rating (250VAC), fuse type (cartridge glass), response time (fast blow), and physical dimensions (5x20mm). These parts differ only in internal construction characteristics (melting I²t values and DC cold resistance) while preserving the primary protection function. Part 0235.200HXP shares all critical electrical parameters but belongs to Series 235 with a lower melting I²t value (0.00867 vs 0.02) and higher DC cold resistance (3.15 Ohms vs 1.7 Ohms).

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with international safety standards. Selection among equivalents should be based on certification requirements specific to the application:

Littelfuse Series 217 parts (0217.200VXP, 0217.200HXP, 0217.200MXP, 0217.200TXP) carry comprehensive approvals including UL, CE, CSA, VDE, CCC, and KC certifications, making them suitable for global applications requiring multi-standard compliance.

Littelfuse Series 235 (0235.200HXP) holds CE, CSA, KC, and UL certifications. The lower melting I²t value (0.00867) indicates faster thermal response compared to Series 217 parts, suitable for applications requiring more sensitive overcurrent detection.

SCHURTER 0034.1509 carries CCC, cURus, and VDE certifications, appropriate for applications where SCHURTER component qualification is specified.

OptiFuse FSD-200MA holds cURus and IEC 60127 certifications, suitable for applications requiring IEC compliance.

Inventory availability ranges from 722 to 4122 units across all parts, supporting procurement flexibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute 0217.200VXP with 0235.200HXP? A: Yes. Both parts share identical current rating (200mA), voltage rating (250VAC), fuse type (cartridge glass), response time (fast blow), and physical dimensions (5x20mm). The 0235.200HXP has a lower melting I²t value (0.00867 vs 0.02), resulting in faster thermal response. Verify that the application tolerates this faster response characteristic and that required certifications (CE, CSA, KC, UL) meet system requirements.

Q: What is the difference between Littelfuse Series 217 and Series 235? A: Series 217 parts (0217.200VXP, 0217.200HXP, 0217.200MXP, 0217.200TXP) have a melting I²t of 0.02 and DC cold resistance of 1.7 Ohms. Series 235 (0235.200HXP) has a lower melting I²t of 0.00867 and higher DC cold resistance of 3.15 Ohms. This results in faster thermal response in Series 235. Both series maintain the same electrical ratings and physical dimensions.

Q: Can I use SCHURTER 0034.1509 as a direct replacement for Littelfuse 0217.200VXP? A: Yes. The SCHURTER 0034.1509 matches all critical electrical parameters: 200mA current rating, 250VAC voltage rating, fast-blow response, 5x20mm dimensions, and 35A breaking capacity. Verify that SCHURTER certifications (CCC, cURus, VDE) satisfy your application requirements.

Q: Are all substitute parts physically interchangeable? A: Yes. All listed parts share identical physical dimensions (5mm x 20mm) and require the same holder type. Physical installation is interchangeable across all parts.

Q: What certifications does each substitute part carry? A: Littelfuse Series 217 parts carry UL, CE, CSA, VDE, CCC, and KC certifications. Littelfuse Series 235 carries CE, CSA, KC, and UL. SCHURTER 0034.1509 carries CCC, cURus, and VDE. OptiFuse FSD-200MA carries cURus and IEC 60127. Confirm that the selected part's certification profile meets your application and regional requirements.

Q: Does melting I²t affect substitutability? A: Melting I²t determines thermal response speed. Parts with lower melting I²t values (such as 0235.200HXP at 0.00867) respond faster to overcurrent conditions. Parts with higher values (such as FSD-200MA at 0.0256) respond more slowly. Select based on whether your circuit requires fast or moderate thermal response characteristics.

Q: What is the difference between OptiFuse FSD-200MA and Littelfuse parts? A: OptiFuse FSD-200MA maintains identical electrical ratings and physical dimensions. The primary difference is manufacturer and certification profile (cURus and IEC 60127 vs Littelfuse's broader certification set). Melting I²t (0.0256) is slightly higher than Series 217 (0.02) but comparable to SCHURTER (0.0252).
