Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical parameter alignment:

Parametric Equivalents (Full Compatibility): Parts BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, and PCB-1-1/2-R are parametric equivalents to PCH-1-1/2-R. These parts share identical electrical specifications: 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 CSA/UL certifications. These parts are direct substitutes within the PC-Tron® series.

Similar Part (Partial Compatibility): 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, and certifications (AEC-Q200, CE, cURus). This part is classified as similar due to current rating alignment but requires application-specific voltage and breaking capacity verification.

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 in applications currently using PCH-1-1/2-R. All three maintain identical electrical parameters, physical dimensions, and regulatory certifications (CSA, UL). Selection among these three parametric equivalents may be based on inventory availability and supply chain considerations. BK/PCC-1-1/2-R currently maintains the highest inventory level at 2626 pieces.

For Alternative Applications: Part 0698Q1500-01 from Bel Fuse Inc. is suitable only for applications where the higher AC voltage rating (350 V) and lower DC voltage rating (140 V) are acceptable. This part exhibits different electrical characteristics including higher breaking capacity (100A AC / 150A DC) and higher melting I²t (0.64). Physical dimensions differ slightly, and regulatory certifications differ (AEC-Q200, CE, cURus versus CSA, UL). Use of this part requires confirmation that application voltage requirements do not exceed 140 V DC and that alternative certifications satisfy system requirements.

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 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 direct substitutes within the PC-Tron® series.

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

A: The primary differences are voltage ratings and breaking capacity. PCH-1-1/2-R is rated 250 V AC / 450 V DC with 50A AC / 5.9kA DC breaking capacity. The 0698Q1500-01 is rated 350 V AC / 140 V DC with 100A AC / 150A DC breaking capacity. Additionally, melting I²t differs (0.09 versus 0.64), physical dimensions differ slightly, and regulatory certifications differ (CSA/UL versus AEC-Q200/CE/cURus).

Q: Are the physical dimensions identical across all parametric equivalents?

A: Yes. PCH-1-1/2-R, BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, and PCB-1-1/2-R all share identical dimensions of 0.350" L x 0.184" W x 0.345" H (8.89mm x 4.67mm x 8.76mm). The 0698Q1500-01 has slightly different dimensions of 0.329" L x 0.157" W x 0.303" H (8.35mm x 4.00mm x 7.70mm).

Q: Which substitute part has the highest current inventory?

A: BK/PCC-1-1/2-R maintains the highest inventory at 2626 pieces, followed by BK/PCB-1-1/2-R at 1595 pieces, PCB-1-1/2-R at 1180 pieces, and PCH-1-1/2-R at 764 pieces.

Q: Can 0698Q1500-01 be used in applications requiring 450 V DC operation?

A: No. The 0698Q1500-01 is rated for 140 V DC maximum, which is insufficient for applications requiring 450 V DC operation. This part is suitable only for applications where DC voltage does not exceed 140 V.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed (PCH-1-1/2-R, BK/PCB-1-1/2-R, BK/PCC-1-1/2-R, PCB-1-1/2-R, and 0698Q1500-01) are ROHS3 compliant.
