Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical parameter alignment:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: current rating (1.5 A), AC voltage rating (250 V), DC voltage rating (450 V), response time (Fast Blow), breaking capacity (50A AC, 5.9kA DC), melting I²t (0.09), mechanical dimensions, and approval certifications (CSA, UL). These parts are direct replacements with no circuit performance impact.

Similar Parts share the same current rating (1.5 A) and response time (Fast Blow) but differ in voltage ratings and breaking capacity specifications. These parts require circuit-level verification before substitution.

Engineering Selection Recommendations

Parametric Equivalent Substitutes (BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, PCB-1-1/2-R) are approved for direct replacement in applications requiring the BK/PCF-1-1/2-R. All three parts are manufactured by Eaton - Electronics Division within the PC-Tron® series, maintain identical electrical ratings, mechanical dimensions, and hold equivalent CSA and UL certifications. Selection among these equivalents may be based on inventory availability or packaging preference (all supplied in Bulk packaging).

Similar Part (0698Q1500-02) manufactured by Bel Fuse Inc. shares the 1.5 A current rating and Fast Blow response characteristic but operates at different voltage specifications (350 V AC / 140 V DC versus 250 V AC / 450 V DC) and exhibits different breaking capacity and melting I²t values. This part is suitable only for applications where the circuit voltage requirements align with the 0698Q1500-02 specifications. The 0698Q1500-02 carries AEC-Q200, CE, and cURus certifications and operates across -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-1-1/2-R replace BK/PCF-1-1/2-R in all applications?

A: Yes. BK/PCB-1-1/2-R is a parametric equivalent with identical current rating (1.5 A), voltage ratings (250 V AC / 450 V DC), response time (Fast Blow), breaking capacity, melting I²t, physical dimensions, and certifications (CSA, UL). Direct substitution is valid.

Q: What is the difference between BK/PCF-1-1/2-R and 0698Q1500-02?

A: Both are 1.5 A fast blow board mount fuses with through hole radial mounting. The primary differences are voltage ratings (BK/PCF-1-1/2-R: 250 V AC / 450 V DC; 0698Q1500-02: 350 V AC / 140 V DC), breaking capacity (50A AC / 5.9kA DC versus 100A AC / 150A DC), melting I²t (0.09 versus 0.64), physical dimensions, and certifications. Substitution requires verification that circuit voltage and fault current specifications align with the 0698Q1500-02 ratings.

Q: Are all parametric equivalents available in the same packaging?

A: BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, and PCB-1-1/2-R are all supplied in Bulk packaging. The similar part 0698Q1500-02 is supplied in Cut Tape (CT) packaging. Packaging format may influence procurement and assembly processes.

Q: Do all substitute parts meet the same compliance standards?

A: Parametric equivalents (BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, PCB-1-1/2-R) hold CSA and UL certifications matching the original BK/PCF-1-1/2-R. The similar part 0698Q1500-02 holds AEC-Q200, CE, and cURus certifications. Compliance requirements for the target application determine which certifications are necessary.

Q: What inventory levels are available for each part?

A: BK/PCF-1-1/2-R: 941 pcs; BK/PCB-1-1/2-R: 1595 pcs; BK/PCC-1-1/2-R: 2626 pcs; PCB-1-1/2-R: 1180 pcs; 0698Q1500-02: 1928 pcs. All parts are listed as new original stock.
