Equivalent & Substitute Parts for PCI-5-R

Part Overview

The PCI-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 and is approved by CSA and UL standards. The part is currently active in production with 905 units in stock. Alternative equivalent and substitute parts are available to support procurement flexibility, inventory management, and application-specific requirements where voltage or performance characteristics differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCI-5-R are classified into two categories based on electrical and mechanical parameter alignment:

Direct Manufacturer Equivalents maintain 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, through-hole radial mounting, and CSA/UL approval. These parts are interchangeable without application redesign.

Parametric Equivalents share the same current rating (5 A), mounting type (through-hole radial), response time (fast-blow), and physical package dimensions, but operate at different voltage ratings. These parts are suitable for applications where the voltage specification differs from the primary requirement.

The substitution logic is determined by the following key parameters:

• Current Rating (Amps)
• Voltage Rating - AC
• Voltage Rating - DC
• Mounting Type
• Response Time
• Package / Case
• Breaking Capacity @ Rated Voltage

Parameter Comparison

Engineering Selection Recommendations

PCI-5-R (Primary Part): Select this part for applications requiring 125 V AC and 400 V DC operation with CSA and UL approval. This is the baseline specification with active production status and adequate inventory availability.

BK/PCI-5-R (Direct Equivalent): This part is electrically and mechanically identical to the PCI-5-R and operates under the same voltage and current specifications. It is approved by CSA and UL and maintains the same breaking capacity. Use this part as a direct substitute when the primary part is unavailable or when procurement from alternative Eaton distribution channels is required.

BK/PCD-5-R (Parametric Equivalent): This part maintains identical electrical specifications to the PCI-5-R (125 V AC, 400 V DC, 5 A, fast-blow response) and is approved by CSA and UL. It is suitable for direct substitution in applications where the primary part is unavailable. This part has the highest inventory availability (12,292 units) and is recommended for high-volume procurement requirements.

80815000000 (Littelfuse Inc., Similar Part): This part is suitable only for applications where the voltage specification differs from the primary requirement. It is rated for 250 V AC and 250 V DC, which is higher than the PCI-5-R specification. The current rating (5 A), mounting type (through-hole radial), response time (fast-blow), and physical dimensions are compatible. This part is approved by cULus and is ROHS3 compliant. Use this part only when the application circuit operates at 250 V AC or 250 V DC and does not require the 400 V DC capability of the primary part.

Frequently Asked Questions (FAQ)

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

A: Yes. BK/PCI-5-R is electrically and mechanically identical to PCI-5-R. Both parts share the same current rating (5 A), voltage ratings (125 V AC, 400 V DC), response time (fast-blow), breaking capacity (10kA AC, 4.2kA DC), mounting type (through-hole radial), and approval agencies (CSA, UL). Direct substitution is supported without circuit modification.

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

A: Yes. BK/PCD-5-R is electrically and mechanically identical to PCI-5-R. Both parts share the same current rating (5 A), voltage ratings (125 V AC, 400 V DC), response time (fast-blow), breaking capacity (10kA AC, 4.2kA DC), mounting type (through-hole radial), and approval agencies (CSA, UL). Direct substitution is supported without circuit modification.

Q: When should 80815000000 be used instead of PCI-5-R?

A: The 80815000000 (Littelfuse TE5® 808 series) is suitable only for applications where the circuit operates at 250 V AC and 250 V DC. The PCI-5-R is rated for 125 V AC and 400 V DC. Do not use 80815000000 in circuits designed for the PCI-5-R voltage specification, as the voltage ratings differ. Use 80815000000 only when the application requires 250 V AC / 250 V DC operation.

Q: Are all substitute parts approved by the same certification agencies?

A: PCI-5-R, BK/PCI-5-R, and BK/PCD-5-R are all approved by CSA and UL. The 80815000000 is approved by cULus. All parts are ROHS3 compliant. Verify certification requirements for your specific application before selection.

Q: What is the difference in physical dimensions between these parts?

A: PCI-5-R, BK/PCI-5-R, and BK/PCD-5-R have identical dimensions: 0.350" L x 0.184" W x 0.345" H (8.89mm x 4.67mm x 8.76mm). The 80815000000 has slightly different dimensions: 0.350" L x 0.183" W x 0.350" H (8.90mm x 4.65mm x 8.90mm). These dimensional differences are negligible for through-hole board mount applications and do not affect PCB layout compatibility.

Q: Which substitute part has the best inventory availability?

A: BK/PCD-5-R has the highest inventory availability with 12,292 units in stock, compared to 905 units for PCI-5-R and 742 units for BK/PCI-5-R. For high-volume procurement, BK/PCD-5-R is recommended due to superior stock levels while maintaining full electrical and mechanical compatibility.

Q: What is the difference in breaking capacity between PCI-5-R and 80815000000?

A: PCI-5-R has a breaking capacity of 10kA AC and 4.2kA DC at rated voltage. The 80815000000 has a breaking capacity of 100A AC and 10kA DC at rated voltage. The 80815000000 has higher breaking capacity, which may be beneficial in high-fault-current applications, but it operates at different voltage ratings (250 V AC / 250 V DC versus 125 V AC / 400 V DC).
