Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for BK/PCB-1-SD is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• 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)
• Physical Dimensions: 0.350" L x 0.184" W x 0.345" H (exact match required)
• Breaking Capacity: 50A AC, 5.9kA DC (exact match required)
• Approval Agency: CSA, UL (exact match required)

Direct Manufacturer Equivalents (Eaton - Electronics Division, PC-Tron® Series): The following part numbers meet all primary equivalence criteria and are active products with RoHS3 compliance:

• BK/PCB-1-R
• BK/PCC-1-R
• BK/PCF-1-R
• BK/PCH-1-R
• PCB-1-R
• PCC-1-R
• PCF-1-R
• PCH-1-R

Cross-Manufacturer Alternative: The part 7100.1165.13 (SCHURTER Inc., FRT 250F series) shares the same current rating, AC voltage rating, response time, mounting type, and package configuration. However, this part operates at 250 V DC maximum (versus 450 V DC for the main part) and has different physical dimensions, breaking capacity, and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Direct Eaton PC-Tron® Equivalents:

For applications requiring direct replacement of BK/PCB-1-SD, select from the active Eaton PC-Tron® series alternatives: BK/PCB-1-R, BK/PCC-1-R, BK/PCF-1-R, BK/PCH-1-R, PCB-1-R, PCC-1-R, PCF-1-R, or PCH-1-R. All eight parts maintain identical electrical specifications (1 A, 250 V AC, 450 V DC, fast blow response), mechanical compatibility (through-hole radial box package, 8.89 x 4.67 x 8.76 mm), and regulatory certifications (CSA, UL). These parts are active products with RoHS3 compliance, addressing the non-compliance status of the obsolete BK/PCB-1-SD. Inventory availability ranges from 686 to 6550 pieces across the eight alternatives.

Secondary Consideration - Cross-Manufacturer Alternative:

The SCHURTER 7100.1165.13 (FRT 250F series) is functionally compatible for applications operating at 250 V DC or lower. This part shares the 1 A current rating, 250 V AC voltage rating, fast blow response, through-hole mounting, and radial box package. However, the 7100.1165.13 has a maximum DC voltage rating of 250 V (not 450 V DC), different physical dimensions (11.50 x 5.00 x 8.00 mm versus 8.89 x 4.67 x 8.76 mm), higher breaking capacity (63A AC), and different thermal operating range (-40°C to 85°C). This part is suitable only for designs where the 450 V DC rating is not required and PCB layout accommodates the larger footprint.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-1-R directly replace BK/PCB-1-SD in existing designs?

A: Yes. BK/PCB-1-R is a direct parametric equivalent with identical current rating (1 A), voltage ratings (250 V AC, 450 V DC), response time (fast blow), mounting type (through-hole), package configuration (radial box), physical dimensions (8.89 x 4.67 x 8.76 mm), and breaking capacity (50A AC, 5.9kA DC). The primary difference is product status: BK/PCB-1-R is active with RoHS3 compliance, while BK/PCB-1-SD is obsolete and non-compliant.

Q: What is the difference between the eight Eaton PC-Tron® alternatives?

A: All eight alternatives (BK/PCB-1-R, BK/PCC-1-R, BK/PCF-1-R, BK/PCH-1-R, PCB-1-R, PCC-1-R, PCF-1-R, PCH-1-R) share identical electrical and mechanical specifications. The differences are in part number designation and packaging format (bulk). Selection among these eight parts is based on inventory availability, supplier preference, or internal part numbering conventions. All are functionally interchangeable.

Q: Can SCHURTER 7100.1165.13 be used as a substitute?

A: SCHURTER 7100.1165.13 is a functional alternative only for applications where the maximum DC voltage requirement does not exceed 250 V. This part cannot be used in circuits requiring the full 450 V DC rating of BK/PCB-1-SD. Additionally, the larger physical dimensions (11.50 x 5.00 x 8.00 mm) may require PCB layout modifications. The part is suitable for 1 A, 250 V AC/DC applications with fast blow response and through-hole radial mounting.

Q: Are all substitute parts CSA and UL approved?

A: All eight Eaton PC-Tron® alternatives carry CSA and UL approvals, matching the certification of BK/PCB-1-SD. SCHURTER 7100.1165.13 carries cURus certification, which differs from the CSA/UL combination. Verify certification requirements for your specific application before selecting SCHURTER as an alternative.

Q: What is the inventory status of substitute parts?

A: Inventory availability for Eaton PC-Tron® alternatives ranges from 686 to 6550 pieces in new original stock. BK/PCB-1-R has the highest availability (4046 pieces), followed by BK/PCC-1-R (6550 pieces). SCHURTER 7100.1165.13 has 876 pieces available. Verify current stock levels with your supplier before finalizing procurement decisions.

Q: Does RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance affects material composition and manufacturing processes but does not alter electrical performance, current rating, voltage rating, or response time. All active Eaton alternatives maintain identical electrical specifications to BK/PCB-1-SD while meeting RoHS3 requirements.

Q: Can these fuses be used interchangeably in the same PCB design?

A: Yes, for the eight Eaton PC-Tron® alternatives. All share identical physical dimensions and electrical ratings, enabling direct PCB footprint compatibility. SCHURTER 7100.1165.13 requires PCB layout verification due to different dimensions and should not be assumed interchangeable without design review.
