Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0216.063MXBP is determined by strict equivalence across the following parameters: current rating (63 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (fast blow), physical package dimensions (5mm x 20mm), breaking capacity (1.5 kA), and mounting requirement (holder-based). All identified substitutes maintain identical electrical and mechanical specifications across these critical parameters, ensuring direct interchangeability without circuit redesign or holder modification.

Parameter Comparison

Engineering Selection Recommendations

All five parts listed—0216.063MXBP, 0216.063HXP, and 0216.063MXP from Littelfuse, and BK/S501-63-R and S501-63-R from Eaton—are active products with full RoHS3 compliance and international safety certifications. The Littelfuse variants (0216.063HXP and 0216.063MXP) carry identical approval agencies (CCC, CE, CSA, SEMKO, UR, VDE) as the primary part. The Eaton variants (BK/S501-63-R and S501-63-R) are certified by CCC, CSA, and cULus. Selection between manufacturers should be based on supply availability, lead time requirements, and existing qualification documentation within your organization. All parts are electrically and mechanically interchangeable for the specified 63 mA, 250 V AC/DC ceramic cartridge fuse application.

Frequently Asked Questions (FAQ)

Q: Can I substitute an Eaton S501-63-R for a Littelfuse 0216.063MXBP without circuit modification?

A: Yes. Both parts share identical electrical ratings (63 mA, 250 V AC), fuse type (ceramic cartridge), response time (fast blow), physical dimensions (5mm x 20mm), and breaking capacity (1.5 kA). No circuit redesign is required.

Q: Are there differences in DC cold resistance between the Littelfuse and Eaton parts?

A: Yes. The Littelfuse 0216.063MXBP and its Littelfuse equivalents (0216.063HXP, 0216.063MXP) specify 10.45 Ohms DC cold resistance, while the Eaton variants (BK/S501-63-R, S501-63-R) specify 39 Ohms. This difference does not affect substitutability for standard circuit protection applications but should be verified if DC resistance is a critical design parameter.

Q: What certifications apply to all substitute parts?

A: All five parts hold CCC and CSA certifications. Littelfuse parts additionally carry CE, SEMKO, UR, and VDE approvals. Eaton parts carry cULus certification. Verify that the required certifications for your application are present before selection.

Q: Do all parts require the same holder type?

A: Yes. All parts are ceramic cartridge fuses in the 5mm x 20mm form factor and require a compatible fuse holder for mounting. No holder modification is necessary when substituting between these parts.

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

A: The Littelfuse parts (0216.063MXBP, 0216.063HXP, 0216.063MXP) are rated for -55°C to 125°C. The Eaton parts (BK/S501-63-R, S501-63-R) do not specify an operating temperature range in the provided data.
