Substitute Part Grouping Explanation

Substitution eligibility for the BK/PCF-3-R is determined by strict parametric equivalence across all electrical and mechanical specifications. The substitute parts BK/PCB-3-R, BK/PCC-3-R, and BK/PCH-3-R are classified as parametric equivalents because they maintain identical values for the following critical parameters:

Electrical Parameters:

• Current Rating: 3 A
• Voltage Rating - AC: 250 V
• Voltage Rating - DC: 450 V
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 50 A AC, 4.4 kA DC
• Melting I²t: 0.75

Mechanical Parameters:

• Mounting Type: Through Hole
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: Radial, Box
• Size / Dimension: 0.350" L x 0.184" W x 0.345" H (8.89 mm x 4.67 mm x 8.76 mm)

Compliance Parameters:

• Approval Agency: CSA, UL
• RoHS Status: ROHS3 Compliant
• Series: PC-Tron®
• Product Status: Active

All substitute parts are manufactured by Eaton - Electronics Division and share identical packaging specifications (Bulk). The differences between these parts are limited to internal design variations within the PC-Tron® series that do not affect electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts—BK/PCF-3-R, BK/PCB-3-R, BK/PCC-3-R, and BK/PCH-3-R—are active products manufactured by Eaton - Electronics Division and carry identical CSA and UL approvals. Each part maintains ROHS3 compliance and is suitable for applications requiring 3 A protection at 250 V AC or 450 V DC with fast-blow response characteristics.

Selection between these parts should be based on inventory availability and procurement lead time requirements. BK/PCB-3-R offers the highest inventory level at 20,099 pieces, making it the optimal choice for applications with extended production runs or immediate delivery requirements. BK/PCC-3-R and BK/PCH-3-R provide intermediate inventory levels of 2,551 and 1,690 pieces respectively. The primary part BK/PCF-3-R maintains 811 pieces in stock.

All substitute parts are electrically and mechanically interchangeable within through-hole radial board mount applications. No design modifications or circuit re-evaluation are required when substituting between these parts.

Frequently Asked Questions (FAQ)

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

A: Yes. All four parts are parametric equivalents with identical electrical ratings (3 A, 250 V AC, 450 V DC), response time (Fast Blow), mechanical dimensions (0.350" L x 0.184" W x 0.345" H), mounting type (Through Hole), and regulatory approvals (CSA, UL). They are direct substitutes for board mount applications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching current rating, AC/DC voltage ratings, response time, breaking capacity, melting I²t value, mounting type, package configuration, physical dimensions, and regulatory approvals. All substitute parts maintain identical values across these parameters.

Q: Are there any differences in performance between BK/PCF-3-R and its substitutes?

A: No performance differences exist. All parts share identical electrical characteristics including 50 A AC and 4.4 kA DC breaking capacity at rated voltage, and 0.75 melting I²t value. Differences are limited to internal design variations within the PC-Tron® series that do not affect circuit protection performance.

Q: Which substitute part should be selected for high-volume production?

A: BK/PCB-3-R is recommended for high-volume applications due to its significantly higher inventory level of 20,099 pieces compared to 2,551 pieces (BK/PCC-3-R) and 1,690 pieces (BK/PCH-3-R).

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. BK/PCF-3-R, BK/PCB-3-R, BK/PCC-3-R, and BK/PCH-3-R all carry CSA and UL approvals and maintain ROHS3 compliance. All parts are active products in the PC-Tron® series.

Q: Are physical dimensions identical across all substitute parts?

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