Engineering Selection Recommendations

All substitute parts listed are direct electrical and mechanical equivalents to the obsolete BK/PCC-3. Selection among active alternatives should be based on the following factors:

Product Status: The BK/PCC-3 is obsolete. All substitute parts carry active product status, ensuring ongoing availability and manufacturing support.

Regulatory Compliance: The BK/PCC-3 is RoHS non-compliant. All substitute parts are RoHS3 compliant, meeting current environmental and regulatory requirements for new designs and production.

Certification: All substitute parts maintain CSA and UL approval agency certifications, preserving the safety and performance standards of the original component.

Inventory Availability: Substitute parts demonstrate varying inventory levels. BK/PCB-3-R offers the highest inventory position (20,099 units), followed by BK/PCC-3-R (2,551 units) and BK/PCH-3-R (1,690 units). Selection based on supply chain requirements and lead time considerations is appropriate.

Direct Manufacturer Equivalents: BK/PCC-3-R and PCC-3-R are direct manufacturer designations for the active equivalent. These parts represent the primary substitution path from the obsolete BK/PCC-3.

Parametric Equivalents: BK/PCB-3-R, BK/PCF-3-R, BK/PCH-3-R, PCB-3-R, PCF-3-R, and PCH-3-R are parametric equivalents within the PC-Tron® series, offering identical electrical and mechanical performance with active status and RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can BK/PCC-3 be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts are electrically and mechanically equivalent to the BK/PCC-3. They share identical current ratings (3 A), voltage ratings (250 V AC / 450 V DC), response characteristics (fast blow), breaking capacity (50 A AC / 4.4 kA DC), physical dimensions (0.350" x 0.184" x 0.345"), and mounting configuration (through-hole radial). Direct substitution is supported without circuit modification.

Q: What is the difference between BK/PCC-3-R and PCC-3-R?

A: Both parts are direct manufacturer equivalents with identical electrical and mechanical specifications. The primary difference is the part number designation. BK/PCC-3-R includes the "BK" prefix, while PCC-3-R does not. Both are active products with RoHS3 compliance. Selection between them may be based on internal part numbering systems or supplier availability.

Q: Are the parametric equivalents (BK/PCB-3-R, BK/PCF-3-R, BK/PCH-3-R, PCB-3-R, PCF-3-R, PCH-3-R) suitable for all applications using BK/PCC-3?

A: Yes. All parametric equivalents meet the same electrical and mechanical requirements as the BK/PCC-3. They are manufactured by Eaton within the PC-Tron® series and carry identical ratings for current, voltage, response time, breaking capacity, and physical dimensions. They are suitable for direct substitution in all applications.

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

A: RoHS3 compliance indicates adherence to current environmental and regulatory standards for electronic components. The original BK/PCC-3 is RoHS non-compliant. All substitute parts are RoHS3 compliant, making them appropriate for new designs and production systems subject to modern regulatory requirements.

Q: Does the packaging type affect substitutability?

A: All substitute parts are supplied in bulk packaging, whereas the original BK/PCC-3 was supplied in box packaging. This difference does not affect electrical or mechanical compatibility. Bulk packaging is standard for active product lines and does not impact circuit performance or installation.

Q: Which substitute part should be selected for new designs?

A: For new designs, any of the active substitute parts are appropriate. BK/PCC-3-R and PCC-3-R represent the direct manufacturer equivalents and are recommended as primary choices. If higher inventory availability is a consideration, BK/PCB-3-R offers the largest stock position. All parts carry identical performance specifications and RoHS3 compliance.

Q: Are all substitute parts certified by CSA and UL?

A: Yes. All substitute parts maintain CSA and UL approval agency certifications, identical to the original BK/PCC-3. This ensures compliance with safety standards and performance requirements across all applications.

Q: Can substitute parts be used interchangeably in existing designs?

A: Yes. All substitute parts are direct electrical and mechanical equivalents. They share identical current ratings, voltage ratings, response characteristics, breaking capacity, physical dimensions, and mounting configuration. Interchangeable use in existing designs is supported without modification.
