Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/GDB-16A are identified based on strict equivalence of the following critical parameters:

• Current Rating: 16 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Mounting Type: Requires Holder (exact match required)

Both substitute parts—FSC-16A and FSD-16A, both manufactured by OptiFuse—meet all critical electrical and mechanical parameters. These parts are functionally interchangeable with the BK/GDB-16A in applications where the specified parameters are required. Differences in breaking capacity, approval agencies, and operating temperature ranges are secondary characteristics that do not affect substitution eligibility based on the core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BK/GDB-16A, FSC-16A, and FSD-16A—are active products with current production status. Selection among these parts is based on the following factors:

BK/GDB-16A (Eaton - Electronics Division): Primary choice when Eaton sourcing is specified or preferred. RoHS Compliant status confirmed. 1057 pieces currently in stock.

FSC-16A (OptiFuse): Suitable for applications requiring UL 248 approval certification. Operating temperature range -55°C to 90°C. Breaking capacity 1kA at rated voltage. ROHS3 Compliant. 3684 pieces in stock inventory.

FSD-16A (OptiFuse): Suitable for applications requiring IEC 60127 approval certification. Extended operating temperature range -55°C to 125°C. Breaking capacity 35A at rated voltage. ROHS3 Compliant and REACH Unaffected. 1401 pieces in stock inventory.

All three parts satisfy the core electrical and mechanical requirements for 16 A, 250 V AC/DC fast-blow glass cartridge fuse applications in 5mm x 20mm form factor. Selection should be based on specific approval agency requirements, operating temperature constraints, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can FSC-16A and FSD-16A be used interchangeably with BK/GDB-16A?

A: Yes. All three parts meet the critical electrical and mechanical parameters: 16 A current rating, 250 V AC voltage rating, fast-blow response time, glass cartridge type, and 5mm x 20mm package dimensions. They are functionally equivalent for applications within these specifications.

Q: What is the difference between FSC-16A and FSD-16A?

A: Both parts are 16 A, 250 V fast-blow glass cartridge fuses in 5mm x 20mm form factor. FSC-16A carries UL 248 approval and operates from -55°C to 90°C with 1kA breaking capacity. FSD-16A carries IEC 60127 approval, operates from -55°C to 125°C with 35A breaking capacity, and is REACH Unaffected. Selection depends on required approval agency and operating temperature range.

Q: Are these fuses compatible with existing 5mm x 20mm fuse holders?

A: Yes. All three parts require a holder and are designed for 5mm x 20mm form factor holders. Physical dimensions are identical: 0.205" diameter x 0.787" length (5.20mm x 20.00mm).

Q: What approval certifications are available?

A: BK/GDB-16A does not specify an approval agency. FSC-16A carries UL 248 certification. FSD-16A carries IEC 60127 certification. Selection should be based on application requirements and regional compliance standards.

Q: Are all three parts RoHS compliant?

A: Yes. BK/GDB-16A is RoHS Compliant. FSC-16A and FSD-16A are both ROHS3 Compliant. All parts meet RoHS requirements.

Q: What is the inventory status for each part?

A: BK/GDB-16A: 1057 pieces in stock. FSC-16A: 3684 pieces in stock. FSD-16A: 1401 pieces in stock. All parts are available as new original stock.
