Substitute Part Grouping Explanation

Substitution eligibility for the BK-S505SC-1.6-R is determined by strict equivalence across the following critical parameters:

• Current Rating: 1.6 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)

The substitute part 0659P1600-13 manufactured by Bel Fuse Inc. satisfies all mandatory equivalence criteria. Both components are ceramic cartridge fuses with identical electrical ratings, mechanical dimensions, and performance characteristics suitable for direct replacement in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the BK-S505SC-1.6-R and 0659P1600-13 are active products with current manufacturing status. Selection between these components should be based on the following factors:

Eaton BK-S505SC-1.6-R: Holds approvals from BSI, CCC/CQC, CSA, cURus, IMQ, KC, PSE/JET, SEMKO, and VDE. RoHS Compliant status applies. Current inventory: 713 units.

Bel Fuse Inc. 0659P1600-13: Holds approvals from CQC, cURus, PSE, and VDE. ROHS3 Compliant status applies. Operating temperature range specified as -55°C ~ 125°C. REACH Unaffected designation. Current inventory: 1748 units.

Both components satisfy identical electrical and mechanical requirements for 1.6 A, 250 V AC/DC ceramic cartridge fuse applications. The choice between manufacturers may be determined by regional certification requirements, supply availability, or existing qualification documentation within the design organization.

Frequently Asked Questions (FAQ)

Q: Can the 0659P1600-13 be used as a direct replacement for the BK-S505SC-1.6-R?
