Equivalent & Substitute Parts for PCC-1-R Board Mount Fuse

Part Overview

The PCC-1-R is a 1 A, 250 V AC / 450 V DC board mount fuse manufactured by Eaton - Electronics Division under the PC-Tron® series. This fast-blow fuse is designed for through-hole radial mounting in electronic circuit protection applications. The part maintains Active product status with full CSA and UL approval agency certifications. Substitute parts are identified when inventory availability requires alternative sourcing or when equivalent electrical and mechanical specifications are required for design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCC-1-R are classified as parametric equivalents based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following criteria:

Critical Matching Parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 450 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Box (exact match required)
• Breaking Capacity @ Rated Voltage: 50 A AC, 5.9 kA DC (exact match required)
• Melting I²t: 0.02 (exact match required)
• Physical Dimensions: 0.350" L x 0.184" W x 0.345" H (exact match required)
• Approval Agency: CSA, UL (exact match required)

All substitute parts listed maintain identical specifications across these parameters, confirming direct functional and mechanical interchangeability within the PC-Tron® series.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—BK/PCC-1-R, BK/PCB-1-R, PCF-1-R, and PCH-1-R—are direct parametric equivalents to the PCC-1-R. Each part maintains Active product status and carries identical CSA and UL approval certifications. All parts are ROHS3 compliant and belong to the PC-Tron® series.

Selection between the main part and substitutes should be based on inventory availability and supply chain requirements. The BK/PCC-1-R variant offers the highest inventory level at 6,550 pieces, followed by BK/PCB-1-R at 4,046 pieces. The PCH-1-R provides 888 pieces, while PCF-1-R and the original PCC-1-R offer 686 and 767 pieces respectively.

No electrical, mechanical, or compliance differences exist between these parts. All are suitable for direct replacement in circuit protection applications requiring 1 A fast-blow fuse protection at 250 V AC / 450 V DC with through-hole radial board mount configuration.

Frequently Asked Questions (FAQ)

Q: Can BK/PCC-1-R, BK/PCB-1-R, PCF-1-R, and PCH-1-R be used interchangeably with PCC-1-R?

A: Yes. All substitute parts share identical electrical specifications (1 A, 250 V AC, 450 V DC, fast-blow response), mechanical dimensions (0.350" L x 0.184" W x 0.345" H), mounting configuration (through-hole radial), and approval certifications (CSA, UL). Direct substitution is supported without circuit modification.

Q: Are there differences in breaking capacity between PCC-1-R and its substitutes?

A: No. All parts maintain identical breaking capacity ratings of 50 A AC and 5.9 kA DC at rated voltage, with matching melting I²t values of 0.02.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. PCC-1-R and all substitute parts (BK/PCC-1-R, BK/PCB-1-R, PCF-1-R, PCH-1-R) carry CSA and UL approvals and are ROHS3 compliant. No compliance differences exist.

Q: What is the difference between the part number variants?

A: The variants represent different part number designations within the PC-Tron® series. Electrical and mechanical specifications are identical. Differences exist only in part number nomenclature and inventory availability.

Q: Can I substitute a higher current rating fuse for PCC-1-R?

A: No. Fuse current rating must match the circuit protection requirement exactly. Substitution is limited to parts with identical 1 A current rating.

Q: Are the physical dimensions identical across all substitute parts?

A: Yes. All parts share identical dimensions of 0.350" L x 0.184" W x 0.345" H (8.89 mm x 4.67 mm x 8.76 mm), ensuring identical PCB footprint and mounting compatibility.
