Equivalent & Substitute Parts for 5HT 5 Ceramic Fuse

Part Overview

The 5HT 5 is a 5A 250VAC ceramic cartridge fuse manufactured by Bel Fuse Inc., designed for applications requiring slow-blow response characteristics in a 5mm x 20mm form factor. The main part (5HT 5) carries an obsolete product status, making identification of active equivalent parts essential for ongoing system support and procurement. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and holder compatibility to ensure direct interchangeability without circuit modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (5A), AC voltage rating (250V), fuse type (cartridge ceramic), physical dimensions (5mm x 20mm), response characteristic (slow blow), and breaking capacity (1.5kA). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring mechanical fit within existing fuse holders and electrical performance within the protected circuit.

The 5HT 5-R (Bel Fuse Inc.) represents the direct active replacement, sharing identical manufacturer lineage and specifications. The 0215005.TXP (Littelfuse Inc.), BK1/S505-5-R (Eaton Electronics Division), and 0001.2511 (SCHURTER Inc.) are functionally equivalent alternatives from established fuse manufacturers, each meeting the same electrical and dimensional requirements.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, the 5HT 5-R is the primary recommended substitute, as it maintains Bel Fuse Inc. manufacturer continuity and carries active product status with ROHS3 compliance. This part is available in high inventory (58,405 pcs) and includes cURus certification in addition to the original approval agencies.

The 0215005.TXP (Littelfuse Inc.) and BK1/S505-5-R (Eaton Electronics Division) are qualified alternatives with active status and ROHS3 compliance. Both parts carry comprehensive international certifications (CCC, CSA, VDE, PSE) and are suitable for direct substitution where multi-source qualification is required.

The 0001.2511 (SCHURTER Inc.) is functionally equivalent with the addition of 150V DC rating specification, providing enhanced documentation for DC circuit applications. This part carries active status and ROHS3 compliance with established certifications.

All substitute parts are mechanically and electrically interchangeable with the 5HT 5 within the specified operating parameters. Selection among active alternatives should be based on supply chain availability, certification requirements specific to the end application, and organizational procurement preferences.

Frequently Asked Questions (FAQ)

Q: Can the 5HT 5-R directly replace the obsolete 5HT 5 without any circuit modifications?

A: Yes. The 5HT 5-R maintains identical electrical ratings (5A, 250VAC), fuse type (ceramic cartridge), physical dimensions (5mm x 20mm), response characteristic (slow blow), and breaking capacity (1.5kA). No circuit modifications are required for direct substitution in existing fuse holders.

Q: What is the primary difference between the main part (5HT 5) and its active replacement (5HT 5-R)?

A: The 5HT 5-R is the active production equivalent with improved RoHS3 compliance status and higher inventory availability. Both parts share identical electrical and mechanical specifications. The main part carries obsolete status, while the 5HT 5-R is actively manufactured.

Q: Are all substitute parts compatible with the same fuse holder?

A: Yes. All substitute parts maintain the 5mm x 20mm physical dimensions and cartridge ceramic form factor, ensuring mechanical compatibility with standard 5x20mm fuse holders. No holder replacement is necessary.

Q: What certifications are common across all substitute parts?

A: All substitute parts carry CCC, CSA, PSE, and VDE certifications. The 5HT 5-R adds cURus certification. The 0215005.TXP includes CE and UL certifications. The BK1/S505-5-R includes BSI, IMQ, and SEMKO certifications. The 0001.2511 includes KC and JET certifications.

Q: Does the 0001.2511 from SCHURTER offer any additional capability?

A: The 0001.2511 specifies a 150V DC rating in addition to the 250V AC rating, providing explicit DC voltage documentation. All other electrical and mechanical parameters remain equivalent to other substitutes.

Q: Which substitute part has the highest inventory availability?

A: The 5HT 5-R has the highest inventory with 58,405 pcs in stock, followed by 0215005.TXP (933 pcs), BK1/S505-5-R (1,674 pcs), and 0001.2511 (6,382 pcs).
