PCF-3/4-R Equivalent & Substitute Parts

Part Overview

The PCF-3/4-R is a board mount fuse manufactured by Eaton - Electronics Division, part of the PC-Tron® series. This through-hole radial fuse is rated for 750 mA at 250 V AC and 450 V DC, with fast-blow response characteristics. The component is classified as Active product status with full CSA and UL approval agency certifications. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in circuit designs without functional compromise.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCF-3/4-R are classified into two categories based on parametric alignment:

Parametric Equivalents (Direct Substitutes): Parts BK/PCB-3/4-R, BK/PCC-3/4-R, and PCB-3/4-R maintain identical electrical specifications across all critical parameters: 750 mA current rating, 250 V AC / 450 V DC voltage ratings, fast-blow response, 50A AC / 5.9kA DC breaking capacity, 0.016 melting I²t, and matching physical dimensions (0.350" L x 0.184" W x 0.345" H). These parts share the same PC-Tron® series designation, through-hole radial mounting configuration, and CSA/UL certifications. All three are manufactured by Eaton - Electronics Division and maintain Active product status with ROHS3 compliance.

Similar Part (Limited Substitution): Part 7100.1164.13 manufactured by SCHURTER Inc. operates within the same functional category but exhibits parameter deviations that restrict direct substitution. This part carries an 800 mA current rating (versus 750 mA), reduced DC voltage rating of 250 V (versus 450 V), different melting I²t of 0.21 (versus 0.016), and altered physical dimensions (0.453" L x 0.197" W x 0.315" H). The breaking capacity is 35A (versus 50A AC / 5.9kA DC). Application compatibility requires verification of circuit voltage and current requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Parametric Equivalents): Parts BK/PCB-3/4-R, BK/PCC-3/4-R, and PCB-3/4-R are qualified for direct substitution with PCF-3/4-R. All three maintain identical electrical ratings, mechanical dimensions, response characteristics, and regulatory certifications. Selection among these three equivalents may be based on inventory availability: BK/PCB-3/4-R (1946 Pcs), BK/PCC-3/4-R (1485 Pcs), or PCB-3/4-R (983 Pcs). All are manufactured by Eaton - Electronics Division with Active product status and ROHS3 compliance.

Limited Substitution (Similar Part): Part 7100.1164.13 from SCHURTER Inc. is not recommended as a direct replacement due to parameter deviations. The reduced DC voltage rating (250 V versus 450 V) and increased melting I²t (0.21 versus 0.016) create functional differences. This part is suitable only for applications where circuit requirements align with its specific electrical characteristics and where the lower DC voltage rating and different thermal response are acceptable.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-3/4-R, BK/PCC-3/4-R, and PCB-3/4-R be used interchangeably with PCF-3/4-R?

A: Yes. These three parts are parametric equivalents with identical current ratings (750 mA), voltage ratings (250 V AC / 450 V DC), response time (fast blow), breaking capacity (50A AC / 5.9kA DC), melting I²t (0.016), physical dimensions, and regulatory certifications. They are direct substitutes.

Q: What are the key differences between PCF-3/4-R and 7100.1164.13?

A: The SCHURTER part 7100.1164.13 differs in four critical parameters: current rating (800 mA versus 750 mA), DC voltage rating (250 V versus 450 V), melting I²t (0.21 versus 0.016), and 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). These differences restrict direct substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PCF-3/4-R, BK/PCB-3/4-R, BK/PCC-3/4-R, PCB-3/4-R, and 7100.1164.13 are all ROHS3 compliant.

Q: What approval agencies certify these fuses?

A: The Eaton parts (PCF-3/4-R and its parametric equivalents) carry CSA and UL certifications. The SCHURTER part 7100.1164.13 carries cURus certification.

Q: Can 7100.1164.13 be used in a 450 V DC circuit?

A: No. The SCHURTER part 7100.1164.13 is rated for 250 V DC maximum, making it unsuitable for circuits requiring 450 V DC operation.

Q: Do the parametric equivalent parts fit the same PCB footprint as PCF-3/4-R?

A: Yes. BK/PCB-3/4-R, BK/PCC-3/4-R, and PCB-3/4-R share identical physical dimensions (0.350" L x 0.184" W x 0.345" H) and through-hole radial mounting configuration with PCF-3/4-R.
