BK/PCE-5-SD Equivalent & Substitute Parts

Part Overview

The BK/PCE-5-SD 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 through-hole radial fuse features fast-blow response characteristics and is rated for 10 kA AC and 1 kA DC breaking capacity. The part is currently obsolete, with 774 pieces available in new original stock. Equivalent and substitute parts are necessary to maintain design continuity and ensure circuit protection in applications where the original part is no longer in production.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/PCE-5-SD are classified into two categories based on electrical and mechanical compatibility:

Direct Manufacturer Equivalents (Eaton - Electronics Division): Parts BK/PCE-5-R, BK/PCD-5-R, BK/PCI-5-R, PCD-5-R, PCG-5-R, and PCI-5-R maintain identical electrical specifications: 5 A current rating, 125 V AC / 400 V DC voltage ratings, fast-blow response, through-hole radial mounting, and CSA/UL approval. These parts are active products with enhanced DC breaking capacity (4.2 kA DC versus 1 kA DC on the original) and RoHS3 compliance. Physical dimensions vary between the original part (0.350" L x 0.184" W x 0.345" H) and BK/PCE-5-R (0.300" L x 0.095" W x 0.170" H), requiring PCB layout verification.

Similar Cross-Manufacturer Parts: Parts 7100.1072.13 (SCHURTER Inc.) and 80815000440 (Littelfuse Inc.) share the same 5 A current rating and fast-blow response but operate at different voltage ratings (250 V AC / 250 V DC). These parts are suitable only for applications where the lower voltage specification is acceptable and do not provide direct substitution for 400 V DC applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Eaton PC-Tron® Series): Parts BK/PCE-5-R, BK/PCD-5-R, BK/PCI-5-R, PCD-5-R, PCG-5-R, and PCI-5-R are direct electrical equivalents with identical voltage and current ratings. All are active products with CSA and UL approval, matching the original certification requirements. These parts provide enhanced DC breaking capacity (4.2 kA versus 1 kA) and RoHS3 compliance. Selection among these equivalents depends on PCB layout constraints due to dimensional variations. BK/PCE-5-R features reduced dimensions (0.300" L x 0.095" W x 0.170" H) compared to the original and other variants (0.350" L x 0.184" W x 0.345" H). Inventory availability ranges from 742 to 12,292 pieces across the active variants.

Secondary Substitutes (Cross-Manufacturer): Parts 7100.1072.13 and 80815000440 are not direct substitutes due to reduced voltage ratings (250 V AC / 250 V DC). These parts are suitable only for applications where the circuit operates below 250 V DC and do not provide equivalent protection for 400 V DC circuits.

Frequently Asked Questions (FAQ)

Q: Can BK/PCE-5-R directly replace BK/PCE-5-SD in existing designs?

A: BK/PCE-5-R is electrically equivalent with identical 5 A, 125 V AC / 400 V DC ratings and fast-blow response. However, physical dimensions differ: BK/PCE-5-R measures 0.300" L x 0.095" W x 0.170" H versus the original 0.350" L x 0.184" W x 0.345" H. PCB layout verification is required before implementation.

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

A: Both parts share identical electrical specifications (5 A, 125 V AC / 400 V DC, fast-blow, 10 kA AC / 4.2 kA DC breaking capacity) and physical dimensions (0.350" L x 0.184" W x 0.345" H). The primary difference is packaging: BK/PCE-5-R is supplied in bulk, while BK/PCD-5-R is also supplied in bulk with higher inventory availability (12,292 pieces).

Q: Are the Eaton PC-Tron® variants (BK/PCD-5-R, BK/PCI-5-R, PCD-5-R, PCG-5-R, PCI-5-R) interchangeable?

A: Yes, all Eaton PC-Tron® variants maintain identical electrical specifications and physical dimensions (0.350" L x 0.184" W x 0.345" H). All are active products with CSA/UL approval and RoHS3 compliance. Selection is based on inventory availability and internal part designation requirements.

Q: Can 7100.1072.13 or 80815000440 be used as substitutes?

A: No. These cross-manufacturer parts operate at 250 V AC / 250 V DC, which is insufficient for applications requiring 400 V DC protection. Use only for circuits operating below 250 V DC.

Q: What is the impact of the enhanced DC breaking capacity in substitute parts?

A: Substitute parts provide 4.2 kA DC breaking capacity compared to 1 kA DC in the original BK/PCE-5-SD. This enhancement improves fault protection capability and is compatible with circuits designed for the original part.

Q: Are all substitute parts RoHS3 compliant?

A: All active Eaton PC-Tron® variants (BK/PCE-5-R, BK/PCD-5-R, BK/PCI-5-R, PCD-5-R, PCG-5-R, PCI-5-R) are RoHS3 compliant. The original BK/PCE-5-SD is RoHS non-compliant. Cross-manufacturer parts 7100.1072.13 and 80815000440 are also RoHS3 compliant.

Q: What certifications apply to substitute parts?

A: All Eaton PC-Tron® variants maintain CSA and UL approval, matching the original part's certification requirements. Cross-manufacturer parts carry cURus (SCHURTER) and cULus (Littelfuse) certifications.
