Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCC-3/4-R are classified into two categories based on parametric alignment:

Direct Equivalents (Identical Electrical and Mechanical Parameters): Parts BK/PCC-3/4-R, BK/PCB-3/4-R, and PCB-3/4-R share all critical electrical specifications with the main part: 750 mA current rating, 250 V AC / 450 V DC voltage ratings, fast blow response, 50A AC / 5.9kA DC breaking capacity, 0.016 melting I²t, identical physical dimensions, and equivalent certifications. These parts are interchangeable at the board level without design modification.

Similar Substitute (Parametric Variation): Part 7100.1064.13 manufactured by SCHURTER Inc. operates within the same functional category but exhibits parameter differences: 800 mA current rating (50 mA higher), 250 V AC / 250 V DC voltage ratings (DC rating reduced by 200 V), different melting I²t value (0.21 versus 0.016), and larger physical dimensions (0.453" L x 0.197" W x 0.315" H). This part is classified as a similar substitute suitable only when design specifications permit the noted parameter variations.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution: Parts BK/PCC-3/4-R, BK/PCB-3/4-R, and PCB-3/4-R are suitable for direct replacement of PCC-3/4-R without circuit redesign. All three parts maintain identical electrical ratings, breaking capacity, melting I²t characteristics, and physical dimensions. All hold Active product status with equivalent regulatory certifications (CSA, UL). Selection among these three direct equivalents may be based on inventory availability and procurement lead times.

For Similar Substitution: Part 7100.1064.13 from SCHURTER Inc. is suitable only when design specifications explicitly permit the following parameter deviations: current rating increase to 800 mA, DC voltage rating reduction to 250 V (from 450 V), melting I²t increase to 0.21 (from 0.016), and physical dimension increase. This part holds Active status with cURus certification. Circuit-level analysis is required to confirm compatibility with the 200 V DC rating reduction and altered thermal response characteristics before implementation.

Frequently Asked Questions (FAQ)

Q: Can BK/PCC-3/4-R be used as a direct replacement for PCC-3/4-R?

A: Yes. BK/PCC-3/4-R is a direct equivalent with identical electrical specifications (750 mA, 250 V AC, 450 V DC), breaking capacity (50A AC, 5.9kA DC), melting I²t (0.016), physical dimensions, and certifications. No circuit modification is required.

Q: What is the difference between BK/PCB-3/4-R and PCB-3/4-R?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications to PCC-3/4-R. The primary difference is inventory availability: BK/PCB-3/4-R has 1946 units in stock versus 983 units for PCB-3/4-R. Electrical performance and physical compatibility are equivalent.

Q: Can 7100.1064.13 replace PCC-3/4-R in all applications?

A: No. The 7100.1064.13 exhibits three critical parameter differences: 50 mA higher current rating (800 mA), 200 V lower DC voltage rating (250 V DC instead of 450 V DC), and significantly higher melting I²t (0.21 versus 0.016). Substitution is limited to applications where these parameter variations are acceptable per design specifications. The reduced DC voltage rating is the primary limiting factor for many high-voltage DC circuits.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including PCC-3/4-R, BK/PCC-3/4-R, BK/PCB-3/4-R, PCB-3/4-R, and 7100.1064.13, hold ROHS3 Compliant status.

Q: What certifications apply to these fuse parts?

A: PCC-3/4-R and its direct equivalents (BK/PCC-3/4-R, BK/PCB-3/4-R, PCB-3/4-R) hold CSA and UL certifications. The similar substitute 7100.1064.13 holds cURus certification. Certification requirements for your application determine which parts are acceptable.

Q: Do the physical dimensions differ between direct equivalents?

A: No. PCC-3/4-R, BK/PCC-3/4-R, BK/PCB-3/4-R, and PCB-3/4-R all share identical dimensions: 0.350" L x 0.184" W x 0.345" H (8.89mm x 4.67mm x 8.76mm). The 7100.1064.13 is larger at 0.453" L x 0.197" W x 0.315" H (11.50mm x 5.00mm x 8.00mm) and may require PCB layout verification before substitution.
