Substitute Part Grouping Explanation

Substitute parts for the BK/PCH-1-1/2-R are classified into two categories based on parametric equivalence:

Parametric Equivalents (Full Compatibility): Parts BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, and PCB-1-1/2-R are direct parametric equivalents. These parts share identical electrical specifications including 1.5 A current rating, 250 V AC / 450 V DC voltage ratings, fast-blow response time, 50A AC / 5.9kA DC breaking capacity, and 0.09 melting I²t value. All three maintain identical physical dimensions (0.350" L x 0.184" W x 0.345" H), through-hole radial mounting configuration, and board mount cartridge-excluded fuse type. All are manufactured by Eaton - Electronics Division within the PC-Tron® series and hold CSA and UL certifications with ROHS3 compliance.

Similar Part (Voltage and Dimensional Variance): Part 0698Q1500-01 manufactured by Bel Fuse Inc. shares the 1.5 A current rating and fast-blow response time but differs in voltage ratings (350 V AC / 140 V DC versus 250 V AC / 450 V DC), breaking capacity (100A AC / 150A DC), melting I²t (0.64), physical dimensions (0.329" L x 0.157" W x 0.303" H), and operating temperature range (-55°C ~ 125°C). This part is classified as similar rather than equivalent due to these parameter differences.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution: Parts BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, and PCB-1-1/2-R are suitable for direct substitution with BK/PCH-1-1/2-R. All three maintain identical electrical and mechanical parameters, identical physical dimensions, and equivalent regulatory certifications (CSA, UL). All parts are active products with ROHS3 compliance. Selection among these three parametric equivalents may be based on inventory availability and lead time considerations.

For Alternative Sourcing: Part 0698Q1500-01 from Bel Fuse Inc. is classified as a similar part rather than a direct equivalent due to voltage rating differences (350 V AC / 140 V DC versus 250 V AC / 450 V DC), higher breaking capacity (100A AC / 150A DC), increased melting I²t (0.64), smaller physical dimensions, and different regulatory certifications (AEC-Q200, CE, cURus). This part is suitable only for applications where the higher AC voltage rating and lower DC voltage rating align with circuit requirements, and where the dimensional and thermal characteristics are compatible with the target application.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, and PCB-1-1/2-R be used interchangeably with BK/PCH-1-1/2-R?

A: Yes. These three parts are parametric equivalents with identical current ratings (1.5 A), voltage ratings (250 V AC / 450 V DC), response time (fast blow), breaking capacity (50A AC / 5.9kA DC), melting I²t (0.09), physical dimensions, and regulatory certifications. They are suitable for direct substitution in any application designed for BK/PCH-1-1/2-R.

Q: What are the key differences between BK/PCH-1-1/2-R and 0698Q1500-01?

A: The primary differences are voltage ratings (BK/PCH-1-1/2-R: 250 V AC / 450 V DC; 0698Q1500-01: 350 V AC / 140 V DC), breaking capacity (50A AC / 5.9kA DC versus 100A AC / 150A DC), melting I²t (0.09 versus 0.64), physical dimensions (0.350" x 0.184" x 0.345" versus 0.329" x 0.157" x 0.303"), and regulatory certifications. The 0698Q1500-01 is not a direct equivalent.

Q: Are all parametric equivalents manufactured by the same company?

A: Yes. BK/PCH-1-1/2-R, BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, and PCB-1-1/2-R are all manufactured by Eaton - Electronics Division within the PC-Tron® series. Part 0698Q1500-01 is manufactured by Bel Fuse Inc. and is classified as a similar part rather than a parametric equivalent.

Q: Do all substitute parts meet the same regulatory requirements?

A: The three parametric equivalents (BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, PCB-1-1/2-R) share identical certifications with the main part: CSA and UL approval. Part 0698Q1500-01 holds different certifications: AEC-Q200, CE, and cURus. Regulatory compliance must be verified against specific application requirements.

Q: Can 0698Q1500-01 be used in applications designed for BK/PCH-1-1/2-R?

A: Part 0698Q1500-01 is not a direct substitute. It differs in voltage ratings, breaking capacity, melting I²t, physical dimensions, and regulatory certifications. Use of this part requires verification that the application's voltage and thermal requirements align with its specifications (350 V AC / 140 V DC, 0.64 melting I²t, smaller dimensions).

Q: What inventory levels are available for each part?

A: BK/PCH-1-1/2-R: 884 pcs; BK/PCB-1-1/2-R: 1595 pcs; BK/PCC-1-1/2-R: 2626 pcs; PCB-1-1/2-R: 1180 pcs; 0698Q1500-01: 8915 pcs. Inventory availability may influence sourcing decisions among parametric equivalents.
