PCH-5-R Equivalent & Substitute Parts

Part Overview

The PCH-5-R is a board mount fuse manufactured by Eaton - Electronics Division, rated for 5 A at 125 V AC. This through-hole radial fuse operates with fast-blow response characteristics and is housed in a radial box package. The component is classified as Active product status and is ROHS3 compliant. Alternative equivalent and substitute parts are identified to support procurement flexibility, inventory management, and application-specific voltage or certification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCH-5-R are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Current Rating: 5 A (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: Radial, Box (exact match required)
• Response Time: Fast Blow (exact match required)
• Physical Dimensions: 0.350" L x 0.184" W x 0.345" H (tolerance within manufacturing specifications)

Secondary Compatibility Factors:

• Voltage Rating - AC: 125 V minimum (substitutes may exceed this rating)
• Voltage Rating - DC: Presence of DC rating in substitute indicates broader application support
• RoHS Status: ROHS3 Compliant (maintained across all alternatives)
• Series Classification: PC-Tron® or equivalent industrial-grade fuse series

Substitutes are grouped into two categories: Parametric Equivalents (BK/PCD-5-R, BK/PCI-5-R) and Similar Parts (80815000000). Parametric equivalents maintain identical current and AC voltage ratings with enhanced DC voltage capability. Similar parts maintain current rating and mounting characteristics but operate at higher voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

BK/PCD-5-R and BK/PCI-5-R (Parametric Equivalents):

These Eaton - Electronics Division parts maintain identical current rating (5 A), AC voltage rating (125 V), mounting configuration, and physical dimensions as the PCH-5-R. Both parts add DC voltage capability (400 V DC) and carry CSA and UL approvals, providing enhanced certification coverage. BK/PCD-5-R offers higher inventory availability (12,292 pcs) compared to BK/PCI-5-R (742 pcs). These parts are direct functional replacements for applications requiring 5 A protection at 125 V AC with optional DC circuit support.

80815000000 (Similar Part - Littelfuse Inc.):

This Littelfuse TE5® 808 series fuse maintains the 5 A current rating and through-hole radial board mount configuration. The part operates at higher voltage ratings (250 V AC / 250 V DC) and carries cULus certification. Physical dimensions are within manufacturing tolerance of the PCH-5-R (0.350" L x 0.183" W x 0.350" H versus 0.350" L x 0.184" W x 0.345" H). This part is suitable for applications where higher voltage protection is required or where Littelfuse component qualification is specified. Inventory availability is 2,705 pcs.

Selection Basis:

All substitute parts maintain Active product status and ROHS3 compliance. Parametric equivalents (BK/PCD-5-R, BK/PCI-5-R) are recommended for direct replacement in existing PCH-5-R applications. The similar part (80815000000) is recommended for new designs requiring higher voltage ratings or Littelfuse supplier qualification.

Frequently Asked Questions (FAQ)

Q: Can BK/PCD-5-R or BK/PCI-5-R be used as direct replacements for PCH-5-R?

A: Yes. Both parts maintain identical current rating (5 A), AC voltage rating (125 V), mounting type (through hole), fuse type (board mount), response time (fast blow), and physical dimensions. The addition of 400 V DC rating does not affect AC-only applications. Both parts carry CSA and UL approvals.

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

A: Both parts are electrically and mechanically identical. The primary difference is inventory availability: BK/PCD-5-R has 12,292 pcs in stock, while BK/PCI-5-R has 742 pcs in stock.

Q: Can 80815000000 replace PCH-5-R in all applications?

A: 80815000000 maintains the 5 A current rating, through-hole mounting, and radial box package. Physical dimensions are within manufacturing tolerance. However, this part is manufactured by Littelfuse Inc. rather than Eaton - Electronics Division and operates at higher voltage ratings (250 V AC / 250 V DC). Substitution is appropriate for applications where higher voltage protection is acceptable or required, or where Littelfuse qualification is specified.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PCH-5-R, BK/PCD-5-R, BK/PCI-5-R, and 80815000000 are all ROHS3 compliant.

Q: What certifications do the substitute parts carry?

A: BK/PCD-5-R and BK/PCI-5-R carry CSA and UL approvals. 80815000000 carries cULus certification. PCH-5-R does not specify approval agencies in the provided data.

Q: Are the physical dimensions of 80815000000 compatible with PCH-5-R footprints?

A: 80815000000 dimensions are 0.350" L x 0.183" W x 0.350" H, compared to PCH-5-R dimensions of 0.350" L x 0.184" W x 0.345" H. Variations are within typical manufacturing tolerances for radial box package fuses. PCB footprint compatibility should be verified for critical applications.

Q: What is the packaging difference between substitute parts?

A: PCH-5-R, BK/PCD-5-R, and BK/PCI-5-R are supplied in Bulk packaging. 80815000000 is supplied in Cut Tape (CT) packaging. This affects handling and automated assembly processes but does not affect component functionality.
