Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: current rating (5A), voltage rating (250VAC), fuse type (cartridge glass), response time (fast blow), physical package dimensions (5x20mm), and mounting requirement (holder-based installation). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring direct functional interchangeability within the same circuit protection application.

The substitute parts are categorized as follows:

Littelfuse Series 217 Parametric Equivalents: Parts 0217005.HXP, 0217005.MXP, 0217005.TXP, and 0217005.MXBP are all Littelfuse manufacturer variants within the same product series, sharing identical electrical ratings, breaking capacity, melting I²t characteristics, and approval certifications.

Cross-Manufacturer Direct Equivalent: Part 0034.1523 from SCHURTER Inc. meets all core electrical parameters (5A, 250VAC, fast-blow, 5x20mm) and maintains equivalent breaking capacity and operating temperature range, though with a different melting I²t value (33.8 versus 42.795).

Cross-Manufacturer Parametric Equivalent: Part FSD-5A from OptiFuse satisfies all primary electrical and mechanical requirements (5A, 250VAC, fast-blow, 5x20mm) with a lower breaking capacity (35A versus 50A) and different melting I²t (58.83 versus 42.795).

Engineering Selection Recommendations

Littelfuse Series 217 Variants (0217005.HXP, 0217005.MXP, 0217005.TXP, 0217005.MXBP): These parts are direct parametric equivalents with identical electrical characteristics, breaking capacity, and melting I²t values. All maintain Active product status and ROHS3 compliance. Selection among these variants is driven by inventory availability and lead time requirements. Part 0217005.MXP offers the highest inventory level (22,400 pcs), followed by 0217005.HXP (15,768 pcs).

SCHURTER 0034.1523: This cross-manufacturer equivalent maintains all critical electrical parameters and breaking capacity. The melting I²t value (33.8) is lower than the Littelfuse reference (42.795), indicating a slightly faster thermal response. This part carries Active product status and ROHS3 compliance with certifications including CCC, cURus, PSE/JET, and VDE. Selection is appropriate when Littelfuse variants are unavailable and the lower melting I²t is acceptable for the application.

OptiFuse FSD-5A: This parametric equivalent meets all primary electrical and mechanical specifications. The breaking capacity is reduced to 35A (versus 50A for Littelfuse), and the melting I²t is elevated to 58.83 (versus 42.795), indicating a slower thermal response. This part maintains Active product status and ROHS3 compliance with cURus and IEC 60127 certifications. Selection requires confirmation that the reduced breaking capacity and altered thermal response are compatible with circuit protection requirements.

Frequently Asked Questions (FAQ)

Q: Can 0217005.HXP be used as a direct replacement for 0217005.VXP?

A: Yes. Both parts are Littelfuse Series 217 variants with identical current rating (5A), voltage rating (250VAC), response time (fast blow), package dimensions (5x20mm), breaking capacity (50A), melting I²t (42.795), and operating temperature range (-55°C to 125°C). They are functionally interchangeable.

Q: What is the difference between the Littelfuse variants (0217005.HXP, 0217005.MXP, 0217005.TXP, 0217005.MXBP)?

A: All four Littelfuse variants share identical electrical and mechanical specifications. The differences are limited to packaging designations and inventory levels. Selection should be based on availability and supply chain requirements.

Q: Can FSD-5A from OptiFuse be used instead of the Littelfuse part?

A: FSD-5A meets the core electrical requirements (5A, 250VAC, fast-blow, 5x20mm). However, it has a lower breaking capacity (35A versus 50A) and a higher melting I²t (58.83 versus 42.795), resulting in slower thermal response. Use only if the application circuit protection requirements are compatible with these altered characteristics.

Q: How does the SCHURTER 0034.1523 compare to the Littelfuse reference part?

A: The SCHURTER part maintains identical current rating, voltage rating, response time, package dimensions, and breaking capacity. The melting I²t is lower (33.8 versus 42.795), indicating a faster thermal response. Both parts are ROHS3 compliant and Active status. The SCHURTER part carries different certifications (CCC, cURus, PSE/JET, VDE) compared to the Littelfuse reference.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (0217005.HXP, 0217005.MXP, 0217005.TXP, 0217005.MXBP, 0034.1523, and FSD-5A) are ROHS3 compliant.

Q: What does "requires holder" mean for mounting?

A: All listed parts are cartridge fuses that require a separate fuse holder for installation. They are not panel-mount or inline components. The holder must accommodate the 5x20mm form factor.

Q: Which substitute part has the best inventory availability?

A: Littelfuse 0217005.MXP has the highest inventory level at 22,400 pcs, followed by 0217005.HXP at 15,768 pcs. OptiFuse FSD-5A has 8,320 pcs available.
