BK/PCB-1-1/2 Equivalent & Substitute Parts

Part Overview

The BK/PCB-1-1/2 is a 1.5 A board mount fuse rated for 250 V AC and 450 V DC operation, manufactured by Eaton - Electronics Division as part of the PC-Tron® series. This component is classified as obsolete, with 1146 pieces currently in stock. The fuse features fast blow response characteristics and is designed for through-hole radial mounting in a box package configuration, excluding cartridge style installations.

Due to the obsolete product status of BK/PCB-1-1/2, identification of active equivalent and substitute parts is necessary to ensure continued availability and design flexibility for new production runs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete BK/PCB-1-1/2 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Electrical Parameters (Must Match Exactly):

• Current Rating: 1.5 A
• Voltage Rating - AC: 250 V
• Voltage Rating - DC: 450 V
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 50A AC, 5.9kA DC
• Melting I²t: 0.09

Mechanical Parameters (Must Match Exactly):

• 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 (8.89mm x 4.67mm x 8.76mm)

Compliance Parameters:

• Approval Agency: CSA, UL
• Series: PC-Tron®

All substitute parts listed below meet these criteria without exception. Packaging format differences (bulk versus box) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are manufactured by Eaton - Electronics Division and maintain active product status, ensuring continued availability and supply chain reliability. The primary distinction between the obsolete BK/PCB-1-1/2 and its active substitutes is regulatory compliance status.

Compliance Considerations:

The original BK/PCB-1-1/2 is classified as RoHS non-compliant. All active substitute parts (BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, BK/PCF-1-1/2-R, BK/PCH-1-1/2-R, PCB-1-1/2-R, PCC-1-1/2-R, PCF-1-1/2-R, PCH-1-1/2-R) are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Inventory Availability:

BK/PCC-1-1/2-R offers the highest inventory level at 2626 pieces, followed by BK/PCB-1-1/2-R at 1595 pieces. All substitute parts maintain sufficient stock for production requirements.

Certification Status:

All substitute parts retain CSA and UL approval agency certifications, maintaining the same safety and performance standards as the original component. The PC-Tron® series designation is consistent across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-1-1/2-R be used as a direct replacement for the obsolete BK/PCB-1-1/2?

A: Yes. BK/PCB-1-1/2-R is electrically and mechanically identical to BK/PCB-1-1/2, with the primary difference being ROHS3 compliance status and active product availability. All electrical parameters, mechanical dimensions, and safety certifications are equivalent.

Q: What is the difference between the various substitute part numbers (BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, BK/PCF-1-1/2-R, etc.)?

A: All substitute parts meet identical electrical and mechanical specifications for 1.5 A, 250 V AC / 450 V DC operation. The different part number designations reflect internal Eaton product line classifications within the PC-Tron® series. From an engineering substitution perspective, all parts are parametrically equivalent and interchangeable.

Q: Are there any packaging differences between substitute parts?

A: Packaging format (bulk versus box) is specified in the inventory data but does not affect electrical or mechanical compatibility. Component selection should be based on procurement and inventory management requirements rather than functional performance.

Q: Do all substitute parts carry the same safety certifications?

A: Yes. All substitute parts maintain CSA and UL approval agency certifications, ensuring compliance with the same safety standards as the original BK/PCB-1-1/2.

Q: Why is RoHS3 compliance important for selecting a substitute?

A: RoHS3 compliance ensures the component meets current environmental regulations for hazardous substance restrictions. For new designs and production runs, ROHS3-compliant parts are required in most markets. The original BK/PCB-1-1/2 is RoHS non-compliant and should be replaced with a compliant alternative for regulatory adherence.

Q: Can I mix different substitute part numbers in the same circuit board design?

A: Yes. All substitute parts are parametrically equivalent and carry identical electrical ratings, breaking capacity, and response characteristics. Mixing part numbers within the same design does not affect circuit performance or safety.

Q: Which substitute part should I select if inventory is a primary concern?

A: BK/PCC-1-1/2-R maintains the highest inventory level at 2626 pieces. However, all substitute parts maintain sufficient stock levels for standard production requirements.
