Equivalent & Substitute Parts for PCD-5-R

Part Overview

The PCD-5-R is a 5 A board mount fuse manufactured by Eaton - Electronics Division, rated for 125 V AC and 400 V DC operation. This through-hole radial fuse is designed for fast-blow response applications and is part of the PC-Tron® series. The component is actively produced and maintains full compliance with RoHS3 standards and CSA/UL approval agencies. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in circuit designs without functional compromise.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCD-5-R are classified into two categories based on parameter alignment:

Direct Equivalent (BK/PCD-5-R): This substitute maintains identical electrical specifications across all critical parameters: 5 A current rating, 125 V AC / 400 V DC voltage ratings, fast-blow response, 10kA AC / 4.2kA DC breaking capacity, and matching physical dimensions. The part is manufactured by the same supplier (Eaton - Electronics Division) within the PC-Tron® series and carries equivalent CSA/UL approvals. This classification permits unrestricted one-to-one replacement.

Parametric Equivalent (BK/PCI-5-R): This substitute shares identical electrical and mechanical specifications with the main part, including current rating, voltage ratings, response time, breaking capacity, dimensions, and approvals. Manufactured by Eaton - Electronics Division within the PC-Tron® series, this part functions as a direct substitute with no performance differentiation.

Similar Part (80815000000): This Littelfuse Inc. component maintains the 5 A current rating and fast-blow response but operates at different voltage ratings (250 V AC / 250 V DC versus 125 V AC / 400 V DC). The breaking capacity differs (100A AC / 10kA DC), and the melting I²t value is lower (1.1584 versus 5). Physical dimensions show minor variation (0.350" L x 0.183" W x 0.350" H). This part is classified as similar due to voltage rating incompatibility with the original specification and is not suitable for direct substitution in applications requiring 400 V DC operation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: BK/PCD-5-R and BK/PCI-5-R are approved substitutes for PCD-5-R. Both parts maintain full electrical and mechanical equivalence, including identical voltage ratings (125 V AC / 400 V DC), current rating (5 A), breaking capacity (10kA AC / 4.2kA DC), and physical dimensions. All three parts carry CSA and UL approvals and comply with RoHS3 standards. Selection between these parts may be based on inventory availability and packaging format (BK/PCD-5-R and BK/PCI-5-R are available in bulk packaging).

For Voltage-Constrained Applications: The part 80815000000 from Littelfuse Inc. is not suitable as a substitute for applications requiring 400 V DC operation. This component is rated for 250 V AC / 250 V DC maximum, which falls below the original specification. Additionally, the melting I²t value (1.1584) differs significantly from the PCD-5-R (5), indicating different thermal response characteristics. Use of this part in circuits designed for 400 V DC operation creates risk of inadequate protection and potential circuit failure.

Compliance Verification: All recommended substitutes (BK/PCD-5-R and BK/PCI-5-R) maintain active product status and full regulatory compliance. Both parts are ROHS3 compliant and carry equivalent approval agency certifications (CSA, UL), ensuring compatibility with existing design documentation and manufacturing standards.

Frequently Asked Questions (FAQ)

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

A: Yes. BK/PCD-5-R is a direct equivalent substitute. It maintains identical electrical specifications (5 A, 125 V AC / 400 V DC), response time (fast-blow), breaking capacity (10kA AC / 4.2kA DC), physical dimensions (0.350" L x 0.184" W x 0.345" H), and regulatory approvals (CSA, UL). Both parts are manufactured by Eaton - Electronics Division within the PC-Tron® series.

Q: What is the difference between BK/PCI-5-R and PCD-5-R?

A: BK/PCI-5-R is a parametric equivalent to PCD-5-R. All critical electrical and mechanical parameters are identical: 5 A current rating, 125 V AC / 400 V DC voltage ratings, fast-blow response, 10kA AC / 4.2kA DC breaking capacity, and matching physical dimensions. Both are manufactured by Eaton - Electronics Division and carry CSA/UL approvals.

Q: Why is 80815000000 not recommended as a substitute?

A: The 80815000000 operates at 250 V AC / 250 V DC, which is below the original PCD-5-R specification of 125 V AC / 400 V DC. This voltage rating incompatibility makes it unsuitable for applications requiring 400 V DC operation. Additionally, the melting I²t value (1.1584) differs from the original (5), indicating different thermal protection characteristics.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. PCD-5-R, BK/PCD-5-R, BK/PCI-5-R, and 80815000000 are all ROHS3 compliant. This ensures compatibility with environmental and regulatory requirements across manufacturing and end-use applications.

Q: What packaging formats are available for substitute parts?

A: BK/PCD-5-R and BK/PCI-5-R are supplied in bulk packaging. The 80815000000 is supplied in cut tape (CT) format. Packaging selection should align with assembly process requirements and inventory management protocols.

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

A: BK/PCD-5-R and BK/PCI-5-R carry CSA and UL approvals, matching the original PCD-5-R. The 80815000000 carries cULus approval. For applications requiring specific approval agency certification, verify that the selected substitute meets the original design specification.
