Key Parameters

Substitute Part Grouping Explanation

Substitute parts for PCB-1-R are classified into two categories based on electrical and mechanical parameter alignment:

Direct Equivalents (Eaton - Electronics Division): Parts BK/PCB-1-R, BK/PCC-1-R, PCF-1-R, and PCH-1-R share identical electrical specifications (1 A, 250 V AC, 450 V DC), matching response time (Fast Blow), breaking capacity (50A AC, 5.9kA DC), melting I²t (0.02), physical dimensions (0.350" L x 0.184" W x 0.345" H), mounting type (Through Hole), package configuration (Radial, Box), and regulatory approvals (CSA, UL). These parts are interchangeable within the PC-Tron® series.

Similar Equivalent (Cross-Manufacturer): Part 7100.1165.13 from SCHURTER Inc. matches current rating (1 A), AC voltage (250 V), mounting type (Through Hole), response time (Fast Blow), and package configuration (Radial, Box). However, DC voltage rating differs (250 V DC versus 450 V DC), physical dimensions vary, breaking capacity differs (63A versus 50A AC), and melting I²t differs (0.18 versus 0.02). This part is suitable only when DC voltage requirements do not exceed 250 V.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Parts BK/PCB-1-R, BK/PCC-1-R, PCF-1-R, and PCH-1-R are fully equivalent to PCB-1-R. All maintain identical electrical ratings, mechanical dimensions, response characteristics, and regulatory certifications. Selection among these Eaton PC-Tron® variants depends on inventory availability and procurement lead times. BK/PCC-1-R offers the highest current inventory (6550 pieces), followed by BK/PCB-1-R (4046 pieces), PCH-1-R (888 pieces), and PCF-1-R (686 pieces).

For Cross-Manufacturer Substitution: Part 7100.1165.13 from SCHURTER Inc. (FRT 250F series) is suitable only when circuit design specifications permit DC voltage operation at 250 V or lower. This part differs in DC voltage rating (250 V versus 450 V), physical dimensions (11.50 x 5.00 x 8.00 mm versus 8.89 x 4.67 x 8.76 mm), breaking capacity (63A versus 50A AC), and melting I²t (0.18 versus 0.02). Regulatory approval differs (cURus versus CSA/UL). PCB layout modifications may be required due to dimensional variance. This substitution is not recommended for applications requiring 450 V DC capability.

Frequently Asked Questions (FAQ)

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

A: Yes. These four parts are parametrically equivalent to PCB-1-R across all critical electrical specifications (1 A, 250 V AC, 450 V DC), response time (Fast Blow), breaking capacity (50A AC, 5.9kA DC), melting I²t (0.02), physical dimensions (8.89 x 4.67 x 8.76 mm), mounting configuration (Through Hole, Radial, Box), and regulatory approvals (CSA, UL). Direct substitution requires no circuit design changes.

Q: Is 7100.1165.13 a suitable replacement for PCB-1-R?

A: Substitution is conditional. The SCHURTER 7100.1165.13 matches current rating (1 A), AC voltage (250 V), mounting type (Through Hole), response time (Fast Blow), and package configuration (Radial, Box). However, DC voltage rating is limited to 250 V, compared to PCB-1-R's 450 V DC capability. Use this part only in applications where maximum DC voltage does not exceed 250 V. Physical dimensions differ (11.50 x 5.00 x 8.00 mm), potentially requiring PCB layout verification.

Q: What are the key parameters that determine fuse substitutability?

A: Substitutability is determined by: current rating (1 A), AC voltage rating (250 V), DC voltage rating (450 V for Eaton parts; 250 V for SCHURTER), response time (Fast Blow), mounting type (Through Hole), package configuration (Radial, Box), breaking capacity, melting I²t, physical dimensions, and regulatory certifications (CSA, UL, or cURus).

Q: Do all substitute parts have the same physical dimensions?

A: Eaton parts (BK/PCB-1-R, BK/PCC-1-R, PCF-1-R, PCH-1-R) share identical dimensions (0.350" L x 0.184" W x 0.345" H / 8.89 x 4.67 x 8.76 mm). The SCHURTER 7100.1165.13 has different dimensions (0.453" L x 0.197" W x 0.315" H / 11.50 x 5.00 x 8.00 mm), requiring PCB footprint verification before substitution.

Q: What is the difference in melting I²t between PCB-1-R and 7100.1165.13?

A: PCB-1-R has a melting I²t of 0.02, while 7100.1165.13 has a melting I²t of 0.18. This indicates different thermal response characteristics. The lower I²t value of PCB-1-R results in faster thermal response to overcurrent conditions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. PCB-1-R, BK/PCB-1-R, BK/PCC-1-R, PCF-1-R, PCH-1-R, and 7100.1165.13 are all ROHS3 compliant, meeting environmental and material restriction requirements.
