Equivalent & Substitute Parts for BK/PCC-3-SD

Part Overview

The BK/PCC-3-SD 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 component is classified as obsolete, with 786 pieces currently in stock. The fuse features fast blow response time, radial box package configuration, and through-hole mounting for PCB integration. Due to its obsolete product status, equivalent and substitute parts from active product lines are available to ensure design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitute parts for the BK/PCC-3-SD are classified into two categories based on electrical and mechanical parameter alignment:

Direct Manufacturer Equivalents (Eaton - Electronics Division): Parts BK/PCC-3-R, BK/PCB-3-R, BK/PCF-3-R, and BK/PCH-3-R are direct substitutes manufactured by Eaton. These parts maintain identical electrical specifications: 3 A current rating, 250 V AC / 450 V DC voltage ratings, fast blow response, 50A AC / 4.4kA DC breaking capacity, and identical physical dimensions. All substitute parts are active products with ROHS3 compliance, addressing the RoHS non-compliance status of the obsolete BK/PCC-3-SD.

Parametric Equivalents (Eaton - Electronics Division without BK prefix): Parts PCB-3-R, PCC-3-R, PCF-3-R, and PCH-3-R are parametric equivalents with identical electrical and mechanical specifications to the prefixed variants. These parts differ only in packaging designation (bulk) and product status (active).

Similar Part (Alternative Manufacturer): Part 80813000440 manufactured by Littelfuse Inc. (808 series) provides functional similarity with the following distinctions: identical 3 A current rating and 250 V AC voltage rating, reduced DC voltage rating of 350 V (versus 450 V), higher breaking capacity of 200A AC / 10kA DC, different melting I²t value of 0.2191, and different approval agencies (cURus, PSE/JET versus CSA, UL). Physical dimensions are comparable with minor variations.

Engineering Selection Recommendations

Primary Substitutes: The Eaton PC-Tron® series parts BK/PCC-3-R, BK/PCB-3-R, BK/PCF-3-R, and BK/PCH-3-R are direct functional replacements for the obsolete BK/PCC-3-SD. These parts provide identical electrical performance, maintain CSA and UL certifications, and offer ROHS3 compliance. Selection among these four variants depends on packaging requirements and inventory availability. BK/PCB-3-R offers the highest inventory level at 20,099 pieces.

Parametric Equivalents: Parts PCB-3-R, PCC-3-R, PCF-3-R, and PCH-3-R (without BK prefix) deliver identical electrical and mechanical specifications to their prefixed counterparts. These parts are suitable for applications where packaging designation does not impose constraints.

Alternative Manufacturer Option: The Littelfuse 80813000440 (808 series) is classified as a similar part rather than a direct substitute due to reduced DC voltage rating (350 V versus 450 V). This part is appropriate only for applications where the maximum DC voltage requirement does not exceed 350 V. The higher breaking capacity (200A AC / 10kA DC) and different approval agencies (cURus, PSE/JET) indicate different performance characteristics and regulatory compliance scope.

Frequently Asked Questions (FAQ)

Q: Can BK/PCC-3-R be used as a direct replacement for BK/PCC-3-SD?

A: Yes. BK/PCC-3-R is a direct substitute with identical electrical specifications (3 A, 250 V AC, 450 V DC, fast blow response), identical physical dimensions, and equivalent breaking capacity. The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant).

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

A: Both parts are manufactured by Eaton with identical electrical and mechanical specifications. The difference is packaging designation: BK/PCC-3-R is supplied in standard packaging, while PCC-3-R is supplied in bulk packaging. Electrical performance and physical dimensions are equivalent.

Q: Is the Littelfuse 80813000440 a suitable replacement?

A: The Littelfuse 80813000440 is a similar part with matching current rating (3 A) and AC voltage rating (250 V). However, the DC voltage rating is reduced to 350 V compared to the 450 V rating of the BK/PCC-3-SD. This part is suitable only for applications where the maximum DC voltage requirement does not exceed 350 V. Approval agencies differ (cURus, PSE/JET versus CSA, UL).

Q: Are all substitute parts physically compatible with the original PCB layout?

A: Yes. All Eaton substitute parts (BK/PCC-3-R, BK/PCB-3-R, BK/PCF-3-R, BK/PCH-3-R, PCB-3-R, PCC-3-R, PCF-3-R, PCH-3-R) maintain identical physical dimensions of 0.350" L x 0.184" W x 0.345" H and radial box package configuration. The Littelfuse 80813000440 has comparable dimensions with minor variations (0.350" L x 0.183" W x 0.350" H).

Q: Which substitute part has the best inventory availability?

A: BK/PCB-3-R offers the highest inventory level at 20,099 pieces in stock, followed by BK/PCH-3-R with 1,690 pieces and BK/PCC-3-R with 2,551 pieces.

Q: Do all substitute parts maintain the same approval certifications?

A: The Eaton substitute parts maintain CSA and UL certifications consistent with the original BK/PCC-3-SD. The Littelfuse 80813000440 carries different certifications (cURus, PSE/JET), indicating different regulatory compliance scope and approval standards.

Q: What is the significance of the melting I²t value?

A: The melting I²t value characterizes the thermal energy required to melt the fuse element. Eaton parts specify 0.75 melting I²t, while the Littelfuse part specifies 0.2191. This difference reflects different fuse element designs and thermal response characteristics. The lower value in the Littelfuse part indicates faster thermal response.
