Substitute Part Grouping Explanation

Substitute parts for the 0217010.MXBP are grouped into two categories based on the following key parameters:

Parametric Equivalents (Littelfuse Series 217): Parts 0217010.HXP, 0217010.TXP, 0217010.VXP, and 0217010.MXP share identical electrical specifications (10A, 250VAC, fast-blow response, 100A breaking capacity) and mechanical dimensions (5x20mm). These parts differ only in packaging variants and regional approval certifications (CE, KC, K-MARK, PSE, VDE combinations). All maintain the same melting I²t value of 217.635 and DC cold resistance of 0.0063 Ohms.

Direct Manufacturer Equivalents: Part 0034.1526 (SCHURTER FSF 5x20 series) and FSD-10A (OptiFuse FSD series) meet the core electrical and mechanical requirements (10A, 250VAC, fast-blow, 5x20mm form factor) but originate from different manufacturers. These parts carry different regulatory approvals and may have variations in breaking capacity and melting I²t characteristics.

Engineering Selection Recommendations

Littelfuse Series 217 Variants (0217010.HXP, 0217010.TXP, 0217010.VXP, 0217010.MXP): These parts are direct parametric equivalents to the 0217010.MXBP with identical electrical performance and thermal characteristics. Selection among these variants depends on regional regulatory requirements and supply availability. All carry ROHS3 compliance and support CE, KC, PSE, and VDE certifications. The 0217010.MXP variant offers the highest inventory availability (17,281 pcs).

SCHURTER 0034.1526 (FSF 5x20 Series): This part meets all core electrical and mechanical specifications with identical 10A/250VAC ratings and 5x20mm dimensions. The melting I²t value of 183 is lower than the Littelfuse reference (217.635), indicating a slightly faster thermal response. This part carries cURus, PSE/JET, and VDE certifications and is suitable for applications where SCHURTER certification is required.

OptiFuse FSD-10A: This part matches the electrical ratings and form factor but has a reduced breaking capacity of 35A compared to 100A for the reference part. The melting I²t of 244.4 indicates a slower thermal response. Selection of this part requires confirmation that the application's fault current does not exceed 35A and that the thermal response characteristics are acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use 0217010.HXP as a direct replacement for 0217010.MXBP? A: Yes. Both parts are Littelfuse Series 217 variants with identical current rating (10A), voltage rating (250VAC), response time (fast-blow), package dimensions (5x20mm), breaking capacity (100A), and melting I²t (217.635). The parts differ only in packaging designation and regional certification combinations.

Q: What is the difference between the Littelfuse variants and the SCHURTER 0034.1526? A: All parts share the same electrical ratings (10A, 250VAC) and mechanical form factor (5x20mm). The SCHURTER part has a lower melting I²t value (183 vs. 217.635), resulting in faster thermal response. Certification requirements and supply chain considerations may influence selection.

Q: Why does the OptiFuse FSD-10A have a lower breaking capacity (35A vs. 100A)? A: The breaking capacity specification reflects the maximum fault current the fuse can safely interrupt. The FSD-10A is suitable for applications where the available fault current does not exceed 35A. Confirmation of application fault current is required before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance status, meeting environmental and hazardous substance restrictions.

Q: Does the operating temperature range differ among substitute parts? A: No. All substitute parts maintain the same operating temperature range of -55°C to 125°C.

Q: Which substitute part has the highest inventory availability? A: The Littelfuse 0217010.MXP variant has the highest inventory with 17,281 pcs in stock.
