Engineering Selection Recommendations

All substitute parts listed provide complete electrical and mechanical equivalence to the BK/PCC-1/2. Selection among active alternatives is based on product availability and regulatory compliance requirements.

Primary Recommendation:

BK/PCC-1/2-R is the direct active equivalent of the obsolete BK/PCC-1/2. This part maintains identical part number nomenclature with the addition of the "-R" suffix, indicating current manufacturing status. It carries ROHS3 compliance and maintains all original electrical specifications and certifications (CSA, UL). Inventory availability is substantial at 3680 pieces.

Alternative Equivalents:

BK/PCB-1/2-R, BK/PCF-1/2-R, and BK/PCH-1/2-R are parametric equivalents within the PC-Tron® series. These parts share identical electrical and mechanical characteristics with the main part and carry ROHS3 compliance. Selection among these alternatives is based on design requirements and supply chain considerations.

PCB-1/2-R, PCC-1/2-R, PCF-1/2-R, and PCH-1/2-R are parametric equivalents without the "BK/" prefix designation. These parts maintain full electrical and mechanical equivalence and ROHS3 compliance status.

All substitute parts are approved by CSA and UL, matching the certification profile of the original component. The "-R" suffix designation across all active alternatives indicates revised manufacturing specifications with improved regulatory compliance.

Frequently Asked Questions (FAQ)

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

A: Yes. BK/PCC-1/2-R is the active equivalent of the obsolete BK/PCC-1/2. Both parts share identical electrical ratings (500 mA, 250 V AC, 450 V DC), response characteristics (fast blow), mechanical configuration (through-hole radial mount, box package), and physical dimensions (0.350" L x 0.184" W x 0.345" H). Both carry CSA and UL certifications. The primary difference is product status and RoHS compliance.

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

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in part number designation. BK/PCC-1/2-R includes the "BK/" prefix, while PCB-1/2-R does not. Both are manufactured by Eaton - Electronics Division, carry ROHS3 compliance, and are CSA/UL certified. Selection between these alternatives depends on design documentation requirements and supply chain availability.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed (those with "-R" suffix or without "BK/PCC-1/2" designation) are ROHS3 compliant. The original BK/PCC-1/2 is RoHS non-compliant. If RoHS compliance is a design requirement, any of the active alternatives satisfy this criterion.

Q: Can I use PCF-1/2-R or PCH-1/2-R instead of BK/PCC-1/2-R?

A: Yes. PCF-1/2-R and PCH-1/2-R are parametric equivalents with identical electrical ratings, response time, mounting configuration, package type, and physical dimensions. All three parts carry CSA and UL certifications and ROHS3 compliance. Selection is based on availability and design documentation requirements.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by exact equivalence across current rating (500 mA), AC voltage (250 V), DC voltage (450 V), response time (fast blow), mounting type (through-hole), fuse type (board mount, cartridge style excluded), package configuration (radial, box), physical dimensions (0.350" L x 0.184" W x 0.345" H), breaking capacity (50A AC, 5.9kA DC), and melting I²t (0.006). All substitute parts meet these criteria.

Q: Is inventory availability a factor in part selection?

A: Inventory levels vary among substitute parts. BK/PCC-1/2-R has the highest availability at 3680 pieces, followed by BK/PCB-1/2-R at 3783 pieces. Other alternatives range from 775 to 1110 pieces. Inventory status should be verified at the time of procurement.

Q: Do all substitute parts have the same approval certifications?

A: Yes. All substitute parts carry CSA and UL approvals, matching the certification profile of the original BK/PCC-1/2. This ensures compliance with the same regulatory standards across all equivalent options.
