Equivalent & Substitute Parts for BK/PCC-2

Part Overview

The BK/PCC-2 is a 2 A, 250 V AC / 450 V DC board mount radial fuse manufactured by Eaton - Electronics Division as part of the PC-Tron® series. This component is classified as obsolete, with 638 pieces available in original stock. The fast-blow response characteristic and CSA/UL approval agency certifications establish this fuse for general-purpose circuit protection in through-hole applications.

Due to the obsolete product status of BK/PCC-2, identification of equivalent and substitute parts is necessary to ensure continued availability and design continuity. Active alternatives meeting identical electrical and mechanical parameters are available from both Eaton and cross-manufacturer sources.

Engineering Selection Recommendations

Eaton PC-Tron® Series (BK/PCC-2-R, PCC-2-R, BK/PCB-2-R, BK/PCF-2-R, BK/PCH-2-R, PCB-2-R, PCF-2-R, PCH-2-R):

These parts provide direct functional equivalence to the obsolete BK/PCC-2. All variants maintain identical electrical specifications (2 A, 250 V AC, 450 V DC, fast-blow response) and mechanical form factor. All are active products with ROHS3 compliance and CSA/UL certifications. Selection among these variants is based on packaging preference (bulk) and inventory availability. BK/PCC-2-R offers the highest inventory level (6446 pieces), ensuring supply continuity.

Littelfuse TE5® 808 Series (80812000075, 80812000440):

These parts satisfy all critical electrical and mechanical substitution criteria while providing enhanced performance characteristics. Breaking capacity is increased to 100A AC and 10kA DC compared to the 50A AC and 5.9kA DC of the original part. Melting I²t is reduced to 0.061 from 0.2, indicating faster thermal response. Operating temperature range extends to -40°C ~ 125°C. These parts carry cULus certification and ROHS3 compliance. The 80812000440 variant offers superior inventory availability (1844 pieces).

Compliance Considerations:

All substitute parts are ROHS3 compliant, addressing regulatory requirements not met by the obsolete BK/PCC-2 (RoHS non-compliant). All substitute parts maintain CSA/UL or cULus approval agency certifications, satisfying safety certification requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. BK/PCC-2-R is a direct equivalent with identical electrical ratings (2 A, 250 V AC, 450 V DC), response time (fast-blow), and mechanical form factor (through-hole radial, box package). The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between the Eaton PC-Tron® variants (BK/PCC-2-R, PCC-2-R, BK/PCB-2-R, etc.)?

A: All Eaton PC-Tron® variants listed meet identical electrical and mechanical specifications. Differences are limited to part number designation and packaging configuration (all are bulk packaged). Selection is based on inventory availability and internal part numbering conventions.

Q: Can Littelfuse 80812000440 replace BK/PCC-2?

A: Yes, with performance enhancement. The 80812000440 meets all critical electrical parameters (2 A, 250 V AC, 450 V DC, fast-blow) and mechanical requirements (through-hole radial, box package). Enhanced specifications include higher breaking capacity (100A AC, 10kA DC vs. 50A AC, 5.9kA DC) and extended operating temperature range (-40°C ~ 125°C).

Q: Are there dimensional differences between substitute parts?

A: Eaton PC-Tron® variants maintain the original dimension specification of 0.350" L x 0.184" W x 0.345" H. Littelfuse TE5® 808 parts have slightly different dimensions (0.350" L x 0.183" W x 0.350" H), with negligible width and height variations that do not affect through-hole board mount compatibility.

Q: Which substitute part offers the best inventory availability?

A: BK/PCC-2-R from Eaton offers the highest inventory level at 6446 pieces. For cross-manufacturer alternatives, Littelfuse 80812000440 provides 1844 pieces in stock.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All substitute parts listed are ROHS3 compliant. The original BK/PCC-2 is RoHS non-compliant, making substitution necessary for applications requiring RoHS compliance.

Q: What approval agencies certify the substitute parts?

A: Eaton PC-Tron® variants carry CSA and UL certifications. Littelfuse TE5® 808 variants carry cULus certification. All certifications satisfy safety requirements for board mount fuse applications.
