Substitute Part Grouping Explanation

Substitute parts for the 0217002.VXP are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Series 217 and 235): Parts 0217002.HXP, 0217002.MXP, 0235002.HXP, 0235002.MXP, and 0235002.VXP share identical current ratings (2A), voltage ratings (250VAC), fuse type (cartridge glass), response time (fast blow), and mechanical dimensions (5x20mm). These parts differ in breaking capacity and melting I²t characteristics but maintain functional equivalence for standard circuit protection applications.

Direct Manufacturer Equivalent (SCHURTER 0034.1519): This part matches all critical electrical parameters and mechanical dimensions. It is manufactured by SCHURTER Inc. under series FSF 5x20 and provides direct substitution capability.

Parametric Equivalent (OptiFuse FSD-2A): This part meets all primary electrical and mechanical specifications, offering an alternative from a different manufacturer within the same product category.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection between Littelfuse Series 217 variants (0217002.HXP, 0217002.MXP) and the main part 0217002.VXP is based on packaging availability and inventory requirements, as electrical and mechanical specifications are identical.

Littelfuse Series 235 variants (0235002.HXP, 0235002.MXP, 0235002.VXP) provide higher breaking capacity (100A versus 35A) and lower melting I²t values, suitable for applications requiring enhanced fault current handling. These parts maintain identical current, voltage, and mechanical ratings.

SCHURTER 0034.1519 offers direct substitution with comparable breaking capacity and melting I²t characteristics. Certification differences include VDE and BSI support in the main part versus cURus and VDE in the SCHURTER equivalent.

OptiFuse FSD-2A provides an alternative from a different manufacturer with matching electrical and mechanical specifications. Certification coverage includes cURus and IEC 60127 compliance.

Frequently Asked Questions (FAQ)

Q: Can Series 235 fuses replace Series 217 fuses in the same application? A: Series 235 fuses share identical current, voltage, and mechanical specifications with Series 217. The primary difference is higher breaking capacity (100A versus 35A) and lower melting I²t. They are mechanically and electrically compatible for direct substitution in standard 5x20mm fuse holders.

Q: What is the significance of melting I²t values in fuse selection? A: Melting I²t indicates the thermal energy required to melt the fuse element. Lower values result in faster response to overcurrent conditions. Series 235 fuses (2.645 I²t) respond faster than Series 217 fuses (5.73 I²t). Selection depends on circuit protection requirements and equipment sensitivity.

Q: Are SCHURTER and OptiFuse equivalents fully interchangeable with Littelfuse parts? A: Yes, SCHURTER 0034.1519 and OptiFuse FSD-2A are mechanically and electrically compatible with the 0217002.VXP. All three share identical 2A current rating, 250VAC voltage rating, fast-blow response, and 5x20mm dimensions. Certification differences should be evaluated against application requirements.

Q: What certifications apply to each substitute part? A: Littelfuse 0217002.VXP carries BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, and VDE certifications. Series 235 variants carry CE, CSA, KC, PSE, and UL certifications. SCHURTER 0034.1519 carries CCC, cURus, PSE/JET, and VDE certifications. OptiFuse FSD-2A carries cURus and IEC 60127 certifications. Application-specific compliance requirements determine appropriate part selection.

Q: Does fuse holder compatibility differ between substitute parts? A: No. All substitute parts maintain the 5x20mm form factor and require standard 5x20mm fuse holders. Physical installation is identical across all listed equivalents.
