Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCB-2-1/2-R is determined by electrical and mechanical parameter alignment. The critical parameters governing substitution are:

Electrical Parameters:

• Current Rating: 2.5 A
• Voltage Rating - AC: 250 V
• Voltage Rating - DC: 450 V (for Eaton direct equivalents) or 250 V (for cross-manufacturer alternatives)
• Response Time: Fast Blow
• Breaking Capacity: 50A AC, 5.9kA DC (for Eaton parts) or 63A (for cross-manufacturer alternatives)
• Melting I²t: 0.3 (for Eaton parts) or 1.2 (for cross-manufacturer alternatives)

Mechanical Parameters:

• Mounting Type: Through Hole
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: Radial, Box
• Physical Dimensions: 0.350" L x 0.184" W x 0.345" H (8.89mm x 4.67mm x 8.76mm) for Eaton parts; 0.453" L x 0.197" W x 0.315" H (11.50mm x 5.00mm x 8.00mm) for cross-manufacturer alternatives

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Approval Agency: CSA, UL (Eaton) or cURus (SCHURTER)

Eaton parts BK/PCB-2-1/2-R, BK/PCC-2-1/2-R, and BK/PCH-2-1/2-R are direct parametric equivalents with identical electrical and mechanical specifications. The SCHURTER part 7100.1169.13 is classified as a similar alternative with differences in DC voltage rating, physical dimensions, melting I²t, and approval agency.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Eaton PC-Tron® Series):

The parts BK/PCB-2-1/2-R, BK/PCC-2-1/2-R, and BK/PCH-2-1/2-R are direct parametric equivalents to the PCB-2-1/2-R. All three parts share identical electrical specifications (2.5 A, 250 V AC, 450 V DC), mechanical dimensions (0.350" L x 0.184" W x 0.345" H), response characteristics (Fast Blow), and regulatory certifications (CSA, UL). These parts are interchangeable for applications requiring the specified current and voltage ratings. Selection among these three Eaton equivalents may be based on inventory availability and procurement lead times.

Cross-Manufacturer Alternative (SCHURTER FRT 250F Series):

The SCHURTER part 7100.1169.13 is a similar alternative with the following differences from the PCB-2-1/2-R:

• DC voltage rating is 250 V (versus 450 V for the Eaton part)
• Physical dimensions are 0.453" L x 0.197" W x 0.315" H (versus 0.350" L x 0.184" W x 0.345" H)
• Breaking capacity is 63A (versus 50A AC, 5.9kA DC)
• Melting I²t is 1.2 (versus 0.3)
• Approval agency is cURus (versus CSA, UL)
• Operating temperature range is specified as -40°C ~ 85°C

The SCHURTER part is suitable for applications where the 250 V DC rating is sufficient and where cURus certification is acceptable. The reduced DC voltage rating and different thermal characteristics require circuit-level evaluation before substitution.

All substitute parts maintain ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can BK/PCB-2-1/2-R be used as a direct replacement for PCB-2-1/2-R?

A: Yes. BK/PCB-2-1/2-R is a direct parametric equivalent with identical current rating (2.5 A), voltage ratings (250 V AC, 450 V DC), response time (Fast Blow), physical dimensions, breaking capacity, and regulatory certifications (CSA, UL).

Q: What is the difference between BK/PCB-2-1/2-R, BK/PCC-2-1/2-R, and BK/PCH-2-1/2-R?

A: These three Eaton parts are parametric equivalents with identical electrical and mechanical specifications. The differences in part number designations reflect internal Eaton product line variations. All three are interchangeable for the specified application requirements.

Q: Can the SCHURTER 7100.1169.13 replace the PCB-2-1/2-R?

A: The SCHURTER 7100.1169.13 is a similar alternative with key differences. The DC voltage rating is 250 V (not 450 V), physical dimensions differ, and the melting I²t is 1.2 (not 0.3). Substitution requires circuit-level evaluation to confirm that the reduced DC voltage rating and different thermal response characteristics are acceptable for the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed—PCB-2-1/2-R, BK/PCB-2-1/2-R, BK/PCC-2-1/2-R, BK/PCH-2-1/2-R, and 7100.1169.13—are ROHS3 compliant.

Q: What regulatory certifications apply to each part?

A: The Eaton parts (PCB-2-1/2-R, BK/PCB-2-1/2-R, BK/PCC-2-1/2-R, BK/PCH-2-1/2-R) carry CSA and UL approvals. The SCHURTER part 7100.1169.13 carries cURus approval. Selection should align with the regulatory requirements of the target application.

Q: Do the physical dimensions differ between Eaton and SCHURTER parts?

A: Yes. Eaton parts measure 0.350" L x 0.184" W x 0.345" H (8.89mm x 4.67mm x 8.76mm). The SCHURTER part measures 0.453" L x 0.197" W x 0.315" H (11.50mm x 5.00mm x 8.00mm). PCB layout and mechanical clearances must be verified before substitution.

Q: What is the melting I²t parameter and why does it differ?

A: Melting I²t is a thermal characteristic that defines the fuse's response to overcurrent conditions. Eaton parts have a melting I²t of 0.3, while the SCHURTER part has 1.2. This difference indicates different thermal response profiles and requires circuit-level analysis to confirm compatibility with the protection scheme.

Q: Are all parts currently in stock?

A: Inventory status is subject to change. The PCB-2-1/2-R has 1160 units in stock, BK/PCB-2-1/2-R has 10134 units, BK/PCC-2-1/2-R has 4389 units, BK/PCH-2-1/2-R has 953 units, and 7100.1169.13 has 906 units. Current availability should be confirmed at the time of procurement.
