Parameter Comparison

Engineering Selection Recommendations

All three part numbers—BK/PCF-1/2-R, BK/PCB-1/2-R, and BK/PCC-1/2-R—are functionally equivalent and maintain identical electrical performance characteristics. Selection between these parts should be based on inventory availability and supply chain considerations.

Compliance Basis: All substitute parts carry identical CSA and UL certifications, ensuring regulatory compliance in applications requiring these approvals. All parts maintain ROHS3 compliance status and Active product status within the PC-Tron® series.

Electrical Performance: The 500 mA current rating, 250 V AC / 450 V DC voltage ratings, fast blow response time, and 0.006 melting I²t value are identical across all three part numbers. Breaking capacity specifications of 50A AC and 5.9kA DC are maintained uniformly.

Mechanical Compatibility: Through hole radial mounting configuration and physical dimensions (0.350" L x 0.184" W x 0.345" H) are identical, ensuring direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-1/2-R and BK/PCC-1/2-R be used interchangeably with BK/PCF-1/2-R?

A: Yes. All three part numbers are parametric equivalents with identical electrical ratings (500 mA, 250 V AC, 450 V DC), response time (fast blow), mechanical dimensions, and certifications (CSA, UL). Direct substitution is supported without circuit modification.

Q: Are there any differences in breaking capacity between these parts?

A: No. All three parts specify identical breaking capacity of 50A AC and 5.9kA DC at rated voltage.

Q: Do all substitute parts have the same physical footprint?

A: Yes. All parts share identical dimensions of 0.350" L x 0.184" W x 0.345" H (8.89mm x 4.67mm x 8.76mm) and use radial, box package configuration for through hole mounting.

Q: Are there any compliance or certification differences?

A: No. All three parts carry identical CSA and UL approvals, maintain ROHS3 compliance, and hold Active product status within the PC-Tron® series.

Q: What is the melting I²t specification and is it identical across all parts?

A: Melting I²t is 0.006 for all three part numbers. This parameter defines the thermal energy required to melt the fuse element and is identical across all substitutes.

Q: Can these parts be used in both AC and DC circuits?

A: Yes. All parts are rated for 250 V AC and 450 V DC operation, supporting dual-voltage application requirements.

Q: What is the response time classification for these fuses?

A: All three parts are classified as fast blow fuses, providing rapid circuit interruption under overcurrent conditions.
