BK/PCF-1-R Equivalent & Substitute Parts

Part Overview

The BK/PCF-1-R is a 1 A, 250 V AC / 450 V DC board mount fuse manufactured by Eaton - Electronics Division as part of the PC-Tron® series. This through-hole radial fuse is designed for fast-blow response applications requiring CSA and UL approval. The component is currently active in production with 1065 pieces in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, supply chain continuity, or inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on parameter alignment with the BK/PCF-1-R:

Parametric Equivalents (Eaton - Electronics Division): BK/PCB-1-R, BK/PCC-1-R, and PCH-1-R are direct parametric equivalents manufactured by Eaton. These parts share identical electrical specifications (1 A, 250 V AC, 450 V DC), response time (Fast Blow), breaking capacity (50A AC, 5.9kA DC), melting I²t (0.02), mechanical dimensions (0.350" L x 0.184" W x 0.345" H), package type (Radial, Box), mounting method (Through Hole), and regulatory approvals (CSA, UL). The part number variant PCF-1-R (without the BK/ prefix) is also a parametric equivalent. These substitutes are interchangeable for applications requiring identical performance characteristics.

Similar Part (Cross-Manufacturer): The SCHURTER 7100.1165.13 is classified as a similar part rather than a parametric equivalent due to differences in DC voltage rating (250 V DC versus 450 V DC), breaking capacity (63A versus 50A AC, 5.9kA DC), melting I²t (0.18 versus 0.02), physical dimensions (0.453" L x 0.197" W x 0.315" H versus 0.350" L x 0.184" W x 0.345" H), and operating temperature range (-40°C ~ 85°C specified). While the AC voltage rating (250 V), current rating (1 A), response time (Fast Blow), mounting type (Through Hole), and package type (Radial, Box) are equivalent, the reduced DC voltage rating and different thermal characteristics limit direct substitution to applications where 250 V DC maximum is acceptable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution: BK/PCB-1-R, BK/PCC-1-R, PCF-1-R, and PCH-1-R are approved for direct substitution in applications currently specified for BK/PCF-1-R. All four parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance (CSA, UL). Selection among these equivalents may be based on inventory availability: BK/PCC-1-R (6550 pcs), BK/PCB-1-R (4046 pcs), PCH-1-R (888 pcs), and PCF-1-R (686 pcs).

For Cross-Manufacturer Substitution: The SCHURTER 7100.1165.13 is suitable only for applications where the DC voltage requirement does not exceed 250 V. This part is not suitable for circuits designed for the full 450 V DC rating of the BK/PCF-1-R. The SCHURTER part carries cURus approval (equivalent to CSA/UL in North American markets) and is ROHS3 compliant. Physical dimensions differ, requiring PCB layout verification before implementation.

All substitute parts listed are active products with current manufacturing status and regulatory compliance documentation available.

Frequently Asked Questions (FAQ)

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

A: Yes. These four parts are parametric equivalents with identical current rating (1 A), AC voltage (250 V), DC voltage (450 V), response time (Fast Blow), breaking capacity (50A AC, 5.9kA DC), melting I²t (0.02), physical dimensions (0.350" L x 0.184" W x 0.345" H), and regulatory approvals (CSA, UL). They are mechanically and electrically interchangeable.

Q: What is the difference between BK/PCF-1-R and PCF-1-R?

A: Both parts are manufactured by Eaton and share identical electrical and mechanical specifications. The difference is in the part number designation; BK/ is a prefix variant. Both are parametric equivalents suitable for direct substitution.

Q: Can the SCHURTER 7100.1165.13 replace BK/PCF-1-R in all applications?

A: No. The SCHURTER part has a reduced DC voltage rating of 250 V compared to the 450 V DC rating of BK/PCF-1-R. It is suitable only for applications where the maximum DC voltage requirement is 250 V or less. Additionally, the physical dimensions differ (0.453" L x 0.197" W x 0.315" H versus 0.350" L x 0.184" W x 0.345" H), requiring PCB layout verification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—BK/PCB-1-R, BK/PCC-1-R, PCF-1-R, PCH-1-R, and 7100.1165.13—are ROHS3 compliant.

Q: What regulatory approvals do these fuses carry?

A: The Eaton parts (BK/PCF-1-R, BK/PCB-1-R, BK/PCC-1-R, PCF-1-R, PCH-1-R) carry CSA and UL approvals. The SCHURTER 7100.1165.13 carries cURus approval.

Q: Which substitute part has the highest inventory availability?

A: BK/PCC-1-R has the highest inventory with 6550 pieces in stock, followed by BK/PCB-1-R (4046 pcs), PCH-1-R (888 pcs), and PCF-1-R (686 pcs).

Q: Do the Eaton parametric equivalents have different operating temperature ranges?

A: Operating temperature data is not provided in the specifications for the Eaton parts. The SCHURTER 7100.1165.13 specifies an operating range of -40°C to 85°C.

Q: What is the melting I²t specification and why does it differ in the SCHURTER part?

A: Melting I²t is a thermal characteristic indicating the energy required to melt the fuse element. The Eaton parts have a melting I²t of 0.02, while the SCHURTER part is 0.18. This difference reflects different fuse element designs and thermal response characteristics. The lower I²t value in Eaton parts indicates faster thermal response.
