Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/PCC-1-1/2 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish direct substitutability:

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):

• Fuse Type: Board Mount (Cartridge Style Excluded)
• Mounting Type: Through Hole
• 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)

Certification (Must Match Exactly):

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

All substitute parts listed below meet these criteria and are classified as active products with RoHS3 compliance, providing improved environmental compliance compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: BK/PCC-1-1/2-R

The BK/PCC-1-1/2-R is the direct active equivalent of the obsolete BK/PCC-1-1/2. This part maintains identical electrical and mechanical specifications while offering RoHS3 compliance and active product status. With 2626 pieces in inventory, this part provides the highest availability for immediate procurement and long-term supply chain stability.

Secondary Recommendations: BK/PCB-1-1/2-R, BK/PCF-1-1/2-R, BK/PCH-1-1/2-R

These parts are parametric equivalents with identical electrical and mechanical characteristics. All three are active products with RoHS3 compliance. Selection among these alternatives should be based on inventory availability and internal part numbering conventions within your organization.

Tertiary Recommendations: PCB-1-1/2-R, PCC-1-1/2-R, PCF-1-1/2-R, PCH-1-1/2-R

These parts are parametric equivalents without the "BK/" prefix designation. They maintain all required electrical and mechanical specifications and are active products with RoHS3 compliance. These alternatives are suitable for applications where prefix designation is not a critical design requirement.

Compliance Advantage:

All substitute parts are RoHS3 compliant, whereas the original BK/PCC-1-1/2 is RoHS non-compliant. This compliance improvement supports adherence to environmental regulations and may be required for new design certifications or procurement policies.

Frequently Asked Questions (FAQ)

Q: Can I use any of the substitute parts interchangeably with the BK/PCC-1-1/2?

A: Yes. All listed substitute parts are parametric equivalents with identical current ratings (1.5 A), voltage ratings (250 V AC / 450 V DC), response time (Fast Blow), breaking capacity (50A AC / 5.9kA DC), melting I²t (0.09), physical dimensions (0.350" L x 0.184" W x 0.345" H), and mounting characteristics (Through Hole, Radial Box package). All are approved by CSA and UL.

Q: What is the difference between BK/PCC-1-1/2-R and PCC-1-1/2-R?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is the part number designation. The "BK/" prefix may indicate internal Eaton classification or packaging designation. Functionally, they are interchangeable. Selection should be based on your organization's part numbering requirements and inventory management practices.

Q: Why should I transition from the obsolete BK/PCC-1-1/2 to an active substitute?

A: The BK/PCC-1-1/2 is classified as obsolete, which creates long-term supply chain risk. Active substitute parts ensure continued availability, support, and compliance with current environmental standards. All substitute parts are RoHS3 compliant, providing improved environmental compliance compared to the non-compliant original part.

Q: Are there any differences in the physical package between the main part and substitutes?

A: No. All parts share identical physical dimensions (0.350" L x 0.184" W x 0.345" H / 8.89mm x 4.67mm x 8.76mm) and package type (Radial, Box). All are Through Hole mounted board mount fuses. Direct PCB layout compatibility is maintained.

Q: Which substitute part has the highest inventory availability?

A: BK/PCC-1-1/2-R has the highest inventory with 2626 pieces in stock, followed by PCB-1-1/2-R with 1180 pieces and PCC-1-1/2-R with 1009 pieces.

Q: Do all substitute parts carry the same certifications as the original?

A: Yes. All substitute parts are approved by CSA and UL, matching the certification profile of the original BK/PCC-1-1/2. All are part of the PC-Tron® series.
