Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on parameter alignment with PCH-2-R:

Direct Manufacturer Equivalents (Eaton - Electronics Division): BK/PCH-2-R, BK/PCB-2-R, and BK/PCC-2-R are Eaton-manufactured variants within the PC-Tron® series. These parts share identical electrical specifications (2 A, 250 V AC, 450 V DC), response time (Fast Blow), mechanical dimensions (0.350" L x 0.184" W x 0.345" H), mounting configuration (Through Hole Radial), and approval certifications (CSA, UL). The prefix variations (BK/, PCB, PCC) represent internal Eaton product line designations without affecting functional equivalence. PCB-2-R is also offered as a non-prefixed variant.

Cross-Manufacturer Equivalents: 80812000440 (Littelfuse Inc., TE5® 808 series) and 7100.1168.13 (SCHURTER Inc., FRT 250F series) provide functional substitution based on matching current rating (2 A), AC voltage (250 V), response time (Fast Blow), mounting type (Through Hole Radial), and package configuration (Radial, Box). These parts carry equivalent or superior approval certifications (cULus for Littelfuse, cURus for SCHURTER).

Engineering Selection Recommendations

Eaton PC-Tron® Series (BK/PCH-2-R, BK/PCB-2-R, BK/PCC-2-R, PCB-2-R): These parts provide direct functional equivalence to PCH-2-R with identical electrical ratings, mechanical dimensions, and CSA/UL certifications. Selection among these variants is determined by internal supply chain availability and part number standardization within Eaton's product portfolio. All variants maintain active product status and ROHS3 compliance.

Littelfuse 80812000440 (TE5® 808 Series): This part meets all critical electrical parameters (2 A, 250 V AC, 450 V DC, Fast Blow) and mechanical specifications (Through Hole Radial, Box package). The part carries cULus certification, which encompasses both CSA and UL standards. Breaking capacity ratings exceed PCH-2-R specifications (100A AC vs. 50A AC; 10kA DC vs. 5.9kA DC), providing enhanced fault protection capability. Dimensional tolerance (8.90 x 4.65 x 8.90 mm) is within acceptable board layout margins relative to PCH-2-R (8.89 x 4.67 x 8.76 mm). Active product status and ROHS3 compliance are confirmed.

SCHURTER 7100.1168.13 (FRT 250F Series): This part matches current rating (2 A), AC voltage (250 V), response time (Fast Blow), and mounting configuration (Through Hole Radial, Box). DC voltage rating is 250 V, which is lower than PCH-2-R (450 V DC). This part is suitable for applications where DC voltage does not exceed 250 V. The part carries cURus certification and maintains active product status with ROHS3 compliance. Dimensional variation (11.50 x 5.00 x 8.00 mm) requires board layout verification for clearance compatibility.

Frequently Asked Questions (FAQ)

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

A: Yes. These Eaton variants share identical electrical specifications (2 A, 250 V AC, 450 V DC), response time (Fast Blow), mechanical dimensions (0.350" L x 0.184" W x 0.345" H), mounting type (Through Hole Radial), and approval certifications (CSA, UL). The prefix and series designations represent internal Eaton product line organization without affecting functional performance.

Q: What is the difference between PCH-2-R and 80812000440?

A: Both parts meet the core electrical requirements (2 A, 250 V AC, 450 V DC, Fast Blow, Through Hole Radial). The Littelfuse 80812000440 offers higher breaking capacity (100A AC / 10kA DC vs. 50A AC / 5.9kA DC) and operates across a wider temperature range (-40°C to 125°C). Dimensional tolerance is negligible (8.90 x 4.65 x 8.90 mm vs. 8.89 x 4.67 x 8.76 mm). Certification is cULus, which covers CSA and UL standards.

Q: Can 7100.1168.13 replace PCH-2-R in all applications?

A: The SCHURTER 7100.1168.13 is suitable for applications where DC voltage does not exceed 250 V. PCH-2-R is rated for 450 V DC. If the circuit design requires 450 V DC operation, 7100.1168.13 is not appropriate. Board layout verification is required due to dimensional differences (11.50 x 5.00 x 8.00 mm vs. 8.89 x 4.67 x 8.76 mm).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (BK/PCH-2-R, BK/PCB-2-R, BK/PCC-2-R, PCB-2-R, 80812000440, and 7100.1168.13) are ROHS3 compliant.

Q: What approval certifications do the substitute parts carry?

A: Eaton variants (BK/PCH-2-R, BK/PCB-2-R, BK/PCC-2-R, PCB-2-R) carry CSA and UL certifications. Littelfuse 80812000440 carries cULus certification. SCHURTER 7100.1168.13 carries cURus certification. All certifications are recognized for board mount fuse applications.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: PCH-2-R (1165 units), BK/PCH-2-R (921 units), BK/PCB-2-R (2481 units), BK/PCC-2-R (6446 units), PCB-2-R (810 units), 80812000440 (1844 units), and 7100.1168.13 (1069 units). Availability may influence selection timing for production schedules.

Q: What is the melting I²t specification, and does it affect substitution?

A: Melting I²t represents thermal energy dissipation characteristics. PCH-2-R specifies 0.2, while 80812000440 specifies 0.061 and 7100.1168.13 specifies 1. These variations reflect different fuse element designs. Selection should be based on circuit protection requirements and thermal coordination with upstream protective devices.
