Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S501-10-R are grouped into parametric equivalents based on the following critical parameters:

Electrical Equivalence Criteria:

• Current Rating: 10 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)

Mechanical Equivalence Criteria:

• Package / Case: 5mm x 20mm (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)

All substitute parts listed meet these criteria and are therefore directly interchangeable with the S501-10-R in applications requiring a 10 A, 250 V AC ceramic cartridge fuse in 5mm x 20mm form factor with fast-blow characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status. Selection among equivalent parts may be based on the following factors:

Approval Agency Certifications: The S501-10-R carries approvals from BSI, CSA, cULus, IMQ, SEMKO, and VDE. Substitute parts carry varying certification portfolios:

• 0216010.HXP and 0216010.VXP (Littelfuse): Certified by CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE
• 0001.1014 (SCHURTER Inc.): Certified by cURus, KC, PSE/JET, and VDE
• FCC-10A (OptiFuse): Certified by cULus and UL 248
• FCD-10A (OptiFuse): Certified by cURus and IEC 60127
• VUC UBM 10A 250V (PF) (Conquer): Certified by CCC, CSA, UL, and VDE

RoHS Compliance: All substitute parts are RoHS3 compliant, matching or exceeding the compliance status of the main part.

Inventory Availability: Substitute parts demonstrate varying stock levels, with 0001.1014 (SCHURTER Inc.) offering the highest inventory at 5,333 pieces.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts directly in place of the S501-10-R?

A: Yes. All listed substitute parts meet the critical electrical and mechanical parameters: 10 A current rating, 250 V AC voltage rating, fast-blow response, 1.5kA breaking capacity, and 5mm x 20mm package dimensions. Direct substitution is supported without circuit modification.

Q: What is the significance of the 5mm x 20mm package dimension?

A: The 5mm x 20mm dimension specifies the physical form factor of the ceramic cartridge fuse. This dimension determines compatibility with standard 5mm x 20mm fuse holders. All substitute parts share this identical dimension and are mechanically interchangeable.

Q: Are there differences in DC cold resistance among the substitute parts?

A: DC cold resistance values vary slightly among manufacturers, ranging from 0.0074 Ohms to 0.008 Ohms. These variations are within normal manufacturing tolerances for ceramic cartridge fuses and do not affect functional interchangeability in standard circuit protection applications.

Q: Does the breaking capacity difference in FCC-10A affect its suitability as a substitute?

A: The FCC-10A has a breaking capacity of 200A, while the S501-10-R and most other substitutes are rated at 1.5kA. The FCC-10A remains electrically and mechanically equivalent for the specified 10 A, 250 V AC application. Breaking capacity represents the maximum fault current the fuse can safely interrupt; the higher rating in other parts provides additional margin but is not required for equivalence.

Q: What approval agencies should I prioritize when selecting a substitute?

A: Selection should be based on the approval agencies required by your application or regional standards. The S501-10-R carries BSI, CSA, cULus, IMQ, SEMKO, and VDE certifications. If your application requires specific certifications, cross-reference the substitute part's approval agency list to ensure compliance.

Q: Is the BK1/S501-10-R variant from Eaton a true equivalent?

A: Yes. The BK1/S501-10-R is a parametric equivalent manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications to the S501-10-R. The primary difference is RoHS compliance designation (RoHS Compliant versus ROHS3 Compliant), which does not affect functional interchangeability.

Q: Can I mix different substitute parts in the same circuit or equipment?

A: All substitute parts are individually qualified as direct replacements for the S501-10-R. However, circuit design and equipment specifications should be consulted to determine whether mixing different fuse manufacturers is permitted in your specific application.
