Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCG-5-R are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters:

• Current Rating: 5 A (exact match required)
• Voltage Rating - AC: 125 V (exact match required)
• Voltage Rating - DC: 400 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 10kA AC, 4.2kA DC (exact match required)
• Melting I²t: 5 (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: Radial, Box (exact match required)
• Size / Dimension: 0.350" L x 0.184" W x 0.345" H / 8.89mm x 4.67mm x 8.76mm (exact match required)

Compliance Parameters:

• Approval Agency: CSA, UL (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Series: PC-Tron® (exact match required)
• Product Status: Active (exact match required)

All identified substitute parts meet these criteria and are direct functional equivalents suitable for board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The PCG-5-R, BK/PCD-5-R, and BK/PCI-5-R are parametrically equivalent components within the PC-Tron® series. All three parts are manufactured by Eaton - Electronics Division and carry identical electrical specifications, mechanical dimensions, and regulatory certifications (CSA, UL). All parts maintain ROHS3 compliance and active product status.

Selection between these three parts is based on availability and inventory levels. The BK/PCD-5-R offers the highest inventory availability at 12,292 units. The PCG-5-R maintains 936 units in stock, while the BK/PCI-5-R has 742 units available. For applications requiring immediate procurement or high-volume orders, inventory status should be the primary selection criterion.

All three parts are suitable for direct substitution in through-hole board mount applications requiring 5 A fast-blow fuse protection at 125 V AC / 400 V DC ratings.

Frequently Asked Questions (FAQ)

Q: Can BK/PCD-5-R or BK/PCI-5-R be used as direct replacements for PCG-5-R?

A: Yes. Both BK/PCD-5-R and BK/PCI-5-R are direct functional equivalents to PCG-5-R. All three parts share identical electrical ratings (5 A, 125 V AC, 400 V DC), response characteristics (fast-blow), mechanical dimensions (0.350" L x 0.184" W x 0.345" H), mounting configuration (through-hole radial), and regulatory approvals (CSA, UL). No circuit board design modifications are required for substitution.

Q: What are the key electrical parameters that must match for substitution?

A: The following electrical parameters must match exactly: current rating (5 A), AC voltage rating (125 V), DC voltage rating (400 V), response time (fast-blow), breaking capacity (10kA AC, 4.2kA DC), and melting I²t value (5).

Q: Are the physical dimensions identical across all three parts?

A: Yes. PCG-5-R, BK/PCD-5-R, and BK/PCI-5-R all share the same physical dimensions of 0.350" L x 0.184" W x 0.345" H (8.89mm x 4.67mm x 8.76mm) in radial, box package configuration. They are mechanically interchangeable in through-hole board mount applications.

Q: Do all substitute parts carry the same regulatory certifications?

A: Yes. All three parts carry CSA and UL approvals and maintain ROHS3 compliance. Regulatory certification status is identical across PCG-5-R, BK/PCD-5-R, and BK/PCI-5-R.

Q: What is the difference between these three part numbers if they are equivalent?

A: The three parts are electrically and mechanically identical. Differences exist only in part number designation and current inventory levels. BK/PCD-5-R has the highest inventory availability (12,292 units), followed by PCG-5-R (936 units) and BK/PCI-5-R (742 units).

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. All three parts are rated for dual-voltage operation: 125 V AC and 400 V DC. They are suitable for use in circuits operating at either voltage rating or in mixed AC/DC applications within these specified limits.

Q: What does "fast-blow" response time mean?

A: Fast-blow indicates the fuse will open quickly when current exceeds the 5 A rating. This response characteristic is identical across all three substitute parts and is suitable for circuits requiring rapid overcurrent protection without delay.
