Substitute Part Grouping Explanation

Substitute parts for the 0217005.TXP are grouped into two categories based on substitution criteria:

Parametric Equivalents (Littelfuse Series 217): Parts 0217005.HXP, 0217005.MXP, and 0217005.MXBP are direct parametric equivalents manufactured by Littelfuse. These parts share identical electrical ratings (5A, 250VAC), response time (Fast Blow), mechanical dimensions (5x20mm), breaking capacity (50A), melting I²t (42.795), operating temperature range (-55°C ~ 125°C), and approval certifications (BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, VDE). The suffix variations (.TXP, .HXP, .MXP, .MXBP) indicate different packaging or internal construction specifications within the same performance class.

Cross-Manufacturer Equivalents: Part 0034.1523 (SCHURTER) and FSD-5A (OptiFuse) are functionally equivalent from different manufacturers. Both match the core electrical parameters (5A, 250VAC, Fast Blow, 5x20mm) and operating temperature range. These parts are substitutable where manufacturer flexibility is acceptable and certifications align with application requirements.

Engineering Selection Recommendations

Littelfuse Series 217 Variants (0217005.HXP, 0217005.MXP, 0217005.MXBP): These parts are direct substitutes for the 0217005.TXP with identical electrical and mechanical specifications. All variants carry the same comprehensive certification portfolio (BSI, CE, CCC, CSA, KC, PSE, SEMKO, UR, VDE) and maintain Active product status. Selection among these variants depends on packaging requirements and internal construction specifications indicated by the suffix designation.

SCHURTER 0034.1523: This part is functionally equivalent with matching core electrical parameters and 5x20mm form factor. The melting I²t value (33.8) is lower than the Littelfuse reference (42.795), indicating faster thermal response. Certifications include CCC, cURus, PSE/JET, and VDE. This part is suitable for applications where SCHURTER certification compliance is required or where the lower I²t characteristic is acceptable.

OptiFuse FSD-5A: This part matches all primary electrical ratings and operating temperature range. The breaking capacity (35A) is lower than the reference (50A), and the melting I²t (58.83) is higher, indicating slower thermal response. Certifications include cURus and IEC 60127. This part is suitable for applications where OptiFuse compliance is required and the lower breaking capacity and higher I²t do not conflict with circuit protection requirements.

Frequently Asked Questions (FAQ)

Q: Can I use 0217005.HXP, 0217005.MXP, or 0217005.MXBP as direct replacements for 0217005.TXP?

A: Yes. These Littelfuse Series 217 variants are parametric equivalents with identical current rating (5A), voltage rating (250VAC), response time (Fast Blow), mechanical dimensions (5x20mm), breaking capacity (50A), and certifications. They are direct functional replacements.

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

A: The suffix designations indicate different packaging or internal construction specifications within the Series 217 product line. All variants maintain identical electrical performance and ratings. Consult manufacturer datasheets for specific packaging differences.

Q: Can I substitute the SCHURTER 0034.1523 for the Littelfuse 0217005.TXP?

A: The SCHURTER 0034.1523 is functionally equivalent in electrical ratings and form factor. However, its melting I²t (33.8) is lower than the Littelfuse reference (42.795), resulting in faster thermal response. Verify that this characteristic is compatible with your circuit protection requirements and that SCHURTER certifications (CCC, cURus, PSE/JET, VDE) satisfy your application standards.

Q: Can I use the OptiFuse FSD-5A as a substitute?

A: The OptiFuse FSD-5A matches the primary electrical ratings (5A, 250VAC) and form factor (5x20mm). However, it has a lower breaking capacity (35A versus 50A) and higher melting I²t (58.83 versus 42.795), indicating slower thermal response. Confirm that these differences are acceptable for your circuit protection design and that OptiFuse certifications (cURus, IEC 60127) meet your application requirements.

Q: Do all substitute parts require the same fuse holder?

A: All listed substitute parts share the same 5x20mm mechanical dimensions and Requires Holder mounting type. They are compatible with standard 5x20mm fuse holders. Verify holder specifications with your equipment manufacturer.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant and REACH Unaffected, meeting environmental compliance requirements.

Q: What is the operating temperature range for these fuses?

A: All substitute parts operate within the -55°C ~ 125°C temperature range, matching the reference part specification.
