Equivalent & Substitute Parts for BK/PCD-5 Board Mount Fuse

Part Overview

The BK/PCD-5 is a 5 A, 125 V AC / 400 V DC board mount fuse manufactured by Eaton - Electronics Division as part of the PC-Tron® series. This component is classified as obsolete, with 647 pieces available in new original stock. The fuse features fast blow response characteristics and is designed for through-hole radial mounting in a box package configuration.

Due to the obsolete product status of BK/PCD-5, equivalent substitute parts from the same manufacturer series are available with active product status and improved compliance ratings. These substitutes maintain identical electrical and mechanical specifications while offering enhanced availability and regulatory compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of BK/PCD-5 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Mandatory Equivalence Parameters:

• Current Rating: 5 A
• Voltage Rating - AC: 125 V
• Voltage Rating - DC: 400 V
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 10 kA AC, 4.2 kA DC
• Melting I²t: 5
• Mounting Type: Through Hole
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: Radial, Box
• 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
• Series: PC-Tron®

All identified substitute parts meet these requirements without exception. Substitutes are classified as direct manufacturer equivalents or parametric equivalents, all manufactured by Eaton - Electronics Division.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: BK/PCD-5-R

BK/PCD-5-R is the direct manufacturer equivalent of BK/PCD-5 with active product status. This part maintains complete electrical and mechanical parity while offering ROHS3 compliance and significantly higher inventory availability (12,292 pieces). Selection of BK/PCD-5-R eliminates obsolescence risk and provides regulatory compliance improvement.

Secondary Recommendations: PCD-5-R, BK/PCI-5-R, PCG-5-R, PCI-5-R

All remaining substitute parts are parametric equivalents within the PC-Tron® series, each with active product status and ROHS3 compliance. These parts are functionally interchangeable with BK/PCD-5 across all specified electrical and mechanical parameters. Selection among these alternatives is determined by packaging requirements and inventory availability:

• PCD-5-R: 774 pieces in stock
• BK/PCI-5-R: 742 pieces in stock
• PCG-5-R: 936 pieces in stock
• PCI-5-R: 905 pieces in stock

All substitute parts carry CSA and UL approval certifications identical to the original part.

Frequently Asked Questions (FAQ)

Q: Can BK/PCD-5-R be used as a direct replacement for BK/PCD-5?

A: Yes. BK/PCD-5-R is a direct manufacturer equivalent with identical electrical specifications (5 A, 125 V AC, 400 V DC), response time (fast blow), breaking capacity (10 kA AC, 4.2 kA DC), physical dimensions (8.89 mm x 4.67 mm x 8.76 mm), and mounting configuration (through-hole radial). The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between direct manufacturer equivalents and parametric equivalents?

A: Direct manufacturer equivalents (BK/PCD-5-R) are designated by the manufacturer as primary replacements for obsolete parts. Parametric equivalents (PCD-5-R, BK/PCI-5-R, PCG-5-R, PCI-5-R) meet all specified electrical and mechanical parameters but may represent alternative product lines within the same series. All are manufactured by Eaton - Electronics Division and are functionally interchangeable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (BK/PCD-5-R, PCD-5-R, BK/PCI-5-R, PCG-5-R, PCI-5-R) are ROHS3 compliant. The original BK/PCD-5 is RoHS non-compliant due to its obsolete status.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All substitute parts maintain identical dimensions of 0.350" L x 0.184" W x 0.345" H (8.89 mm x 4.67 mm x 8.76 mm) and the same radial, box package configuration. Through-hole mounting compatibility is preserved across all substitutes.

Q: What certifications apply to these fuses?

A: All parts, including BK/PCD-5 and all substitutes, carry CSA and UL approval certifications. These certifications are maintained across the entire substitute group.

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

A: BK/PCD-5-R is the recommended selection for new designs due to its designation as the direct manufacturer equivalent, active product status, and highest inventory availability (12,292 pieces). This selection eliminates obsolescence risk and ensures long-term supply continuity.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All substitute parts are electrically identical with 5 A current rating, 125 V AC / 400 V DC voltage ratings, fast blow response, 10 kA AC / 4.2 kA DC breaking capacity, and melting I²t of 5.
