Equivalent & Substitute Parts for PCB-1/2-R

Part Overview

The PCB-1/2-R is a board mount fuse manufactured by Eaton - Electronics Division, part of the PC-Tron® series. This component is a 500 mA, 250 V AC / 450 V DC fast blow fuse designed for through-hole radial mounting in box package configuration. The part is classified as Active product status with full CSA and UL approval agency certifications. Alternative equivalent parts are necessary to support supply chain flexibility, inventory management, and design revision requirements while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCB-1/2-R are classified based on strict electrical and mechanical parameter equivalence. All substitute parts must match the following critical parameters to ensure direct interchangeability:

• Current Rating: 500 mA
• Voltage Rating - AC: 250 V
• Voltage Rating - DC: 450 V
• Response Time: Fast Blow
• Mounting Type: Through Hole
• Package / Case: Radial, Box
• Breaking Capacity @ Rated Voltage: 50A AC, 5.9kA DC
• Melting I²t: 0.006
• Physical Dimensions: 0.350" L x 0.184" W x 0.345" H (8.89mm x 4.67mm x 8.76mm)
• Approval Agency: CSA, UL

The substitute parts BK/PCB-1/2-R and BK/PCC-1/2-R meet all these criteria and are therefore classified as direct equivalents suitable for component replacement without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PCB-1/2-R, BK/PCB-1/2-R, and BK/PCC-1/2-R—are classified as Active products with identical electrical specifications, mechanical dimensions, and regulatory certifications. Selection between these parts is based on availability and supply chain considerations rather than technical performance differences.

BK/PCB-1/2-R carries REACH Unaffected status and maintains 3783 units in stock inventory. BK/PCC-1/2-R also carries REACH Unaffected status with 3680 units in stock. The original PCB-1/2-R maintains 1081 units in stock. All parts comply with ROHS3 requirements and carry CSA and UL approvals suitable for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-1/2-R and BK/PCC-1/2-R be used interchangeably with PCB-1/2-R?

A: Yes. All three parts share identical electrical ratings (500 mA, 250 V AC, 450 V DC), response time (Fast Blow), breaking capacity (50A AC, 5.9kA DC), melting I²t (0.006), physical dimensions (0.350" L x 0.184" W x 0.345" H), mounting type (Through Hole), and package configuration (Radial, Box). They are direct equivalents.

Q: What are the key parameters that determine substitutability for this fuse?

A: Current rating, AC and DC voltage ratings, response time classification, breaking capacity, melting I²t value, physical dimensions, mounting type, and package configuration must all match exactly. All three parts meet these criteria.

Q: Are there any compliance or certification differences between these parts?

A: All three parts carry CSA and UL approvals and are ROHS3 compliant. BK/PCB-1/2-R and BK/PCC-1/2-R carry REACH Unaffected status. No compliance barriers exist for substitution.

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

A: The part numbers reflect manufacturer designation variants within the PC-Tron® series. The "BK/" prefix and letter variations (PCB vs. PCC) represent different production batches or internal classification codes. Electrical and mechanical specifications remain identical across all three designations.

Q: Can I substitute these parts on an existing PCB without layout modifications?

A: Yes. Identical through-hole radial mounting configuration and physical dimensions (0.350" L x 0.184" W x 0.345" H) ensure direct board compatibility without layout changes.
