Substitute Part Grouping Explanation

Substitute parts for the PCF-1/2-R are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Current Rating: 500 mA
• 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: 0.006

Mechanical Parameters (Must Match Exactly):

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

Compliance Parameters (Must Match Exactly):

• Approval Agency: CSA, UL
• RoHS Status: ROHS3 Compliant
• Series: PC-Tron®

The identified substitute parts BK/PCB-1/2-R and BK/PCC-1/2-R meet all specified criteria and are therefore electrically and mechanically interchangeable with the PCF-1/2-R.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PCF-1/2-R, BK/PCB-1/2-R, and BK/PCC-1/2-R—are active production components from Eaton - Electronics Division with identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. Selection between these parts is based on inventory availability and supply chain considerations rather than technical performance differences.

The PCF-1/2-R maintains 775 pieces in current inventory. The substitute parts BK/PCB-1/2-R and BK/PCC-1/2-R provide higher inventory levels at 3783 and 3680 pieces respectively, offering improved supply chain flexibility. All parts carry CSA and UL approvals and maintain ROHS3 compliance, ensuring regulatory acceptance in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Are BK/PCB-1/2-R and BK/PCC-1/2-R direct replacements for PCF-1/2-R?

A: Yes. Both substitute parts are electrically and mechanically equivalent to the PCF-1/2-R. They share identical current ratings (500 mA), voltage ratings (250 V AC, 450 V DC), response time (Fast Blow), physical dimensions (0.350" L x 0.184" W x 0.345" H), and approval certifications (CSA, UL).

Q: What determines substitution eligibility for this fuse category?

A: Substitution is determined by exact matching of current rating, AC/DC voltage ratings, response time classification, breaking capacity, melting I²t value, mounting type, package configuration, physical dimensions, and approval agency certifications. All three parts meet these criteria.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes. The identical through hole radial mounting configuration, box package type, and physical dimensions (8.89mm x 4.67mm x 8.76mm) ensure mechanical and electrical interchangeability in board designs specified for the PCF-1/2-R.

Q: What is the difference between the three part numbers?

A: The three part numbers represent different product variants within the PC-Tron® series from Eaton - Electronics Division. All variants maintain identical electrical performance and mechanical specifications. Differences are limited to internal manufacturing or distribution designations.

Q: Are all three parts RoHS compliant?

A: Yes. PCF-1/2-R, BK/PCB-1/2-R, and BK/PCC-1/2-R are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
