Equivalent & Substitute Parts for PCC-3-R Board Mount Fuse

Part Overview

The PCC-3-R is a 3 A, 250 V AC / 450 V DC board mount fuse manufactured by Eaton - Electronics Division as part of the PC-Tron® series. This fast-blow fuse is designed for through-hole radial mounting on printed circuit boards and operates within a breaking capacity of 50 A AC and 4.4 kA DC at rated voltage. The component is classified as Active product status and carries CSA and UL approvals, making it suitable for industrial and commercial electronic applications requiring overcurrent protection.

Substitute parts become necessary when the primary part number experiences supply constraints, inventory limitations, or when design flexibility permits selection from equivalent alternatives within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the PCC-3-R is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts BK/PCC-3-R, BK/PCB-3-R, and BK/PCH-3-R are classified as direct and parametric equivalents because they maintain identical specifications in the following key areas:

• Current Rating: 3 A
• Voltage Rating - AC: 250 V
• Voltage Rating - DC: 450 V
• Response Time: Fast Blow
• Mounting Type: Through Hole
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: Radial, Box
• Breaking Capacity @ Rated Voltage: 50 A AC, 4.4 kA DC
• Melting I²t: 0.75
• Physical Dimensions: 0.350" L x 0.184" W x 0.345" H (8.89 mm x 4.67 mm x 8.76 mm)
• Approval Agency: CSA, UL
• RoHS Status: ROHS3 Compliant
• Series: PC-Tron®

All substitute parts are manufactured by Eaton - Electronics Division and carry Active product status. Substitution is valid when circuit design requirements match these exact parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts—BK/PCC-3-R, BK/PCB-3-R, and BK/PCH-3-R—are functionally equivalent to the primary PCC-3-R component. Selection among these alternatives is based on availability and inventory status rather than electrical or mechanical performance differences.

BK/PCB-3-R offers the highest inventory availability at 20,099 pieces in stock, making it the preferred choice for high-volume production requirements. BK/PCC-3-R provides 2,551 pieces in stock and serves as a direct manufacturer equivalent. BK/PCH-3-R maintains 1,690 pieces in stock and is suitable for applications where inventory constraints on the primary part number necessitate an alternative.

All parts carry identical CSA and UL approvals, ROHS3 compliance, and Active product status. Selection does not require design modification or circuit re-evaluation when substituting between these part numbers, provided the application circuit design matches the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-3-R be used as a direct replacement for PCC-3-R in existing circuit designs?

A: Yes. BK/PCB-3-R maintains identical electrical ratings (3 A, 250 V AC, 450 V DC), response time (Fast Blow), breaking capacity (50 A AC, 4.4 kA DC), physical dimensions (0.350" L x 0.184" W x 0.345" H), and mounting configuration (Through Hole, Radial, Box). No circuit modification is required.

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

A: These part numbers represent different SKUs within the PC-Tron® series manufactured by Eaton - Electronics Division. All three share identical electrical specifications, mechanical dimensions, and performance characteristics. Differences exist only in part number designation and inventory tracking. Selection is based on availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PCC-3-R, BK/PCC-3-R, BK/PCB-3-R, and BK/PCH-3-R are all ROHS3 compliant and carry CSA and UL approvals.

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

A: Yes. All parts are rated for 250 V AC and 450 V DC operation. The breaking capacity is specified as 50 A AC and 4.4 kA DC at rated voltage.

Q: What does "Fast Blow" response time mean?

A: Fast Blow indicates that the fuse element melts and interrupts the circuit rapidly when current exceeds the 3 A rating. This response characteristic is consistent across all substitute parts.

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

A: Yes. All parts measure 0.350" L x 0.184" W x 0.345" H (8.89 mm x 4.67 mm x 8.76 mm) and use Radial, Box packaging for through-hole PCB mounting.

Q: What is the Melting I²t value and why is it important?

A: The Melting I²t value of 0.75 defines the thermal energy required to melt the fuse element. This parameter is identical across all substitute parts and determines the fuse's response to overcurrent conditions.
