Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CB3JB1R00 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 1 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (maintained)
• REACH status: REACH Unaffected (maintained)

The substitute parts PNP300JR-73-1R and PNP3WVJR-73-1R from YAGEO meet all core electrical specifications. Both are Active status components supplied in Cut Tape packaging with equivalent resistance, tolerance, power rating, and wirewound composition in axial configuration.

Parameter Comparison

Engineering Selection Recommendations

Both YAGEO substitute parts maintain Active product status and full compliance with ROHS3 and REACH requirements, matching the regulatory posture of the original CB3JB1R00. The electrical specifications—1 Ohm resistance, ±5% tolerance, and 3W power rating—are identical across all three parts.

Physical dimensions differ between the main part and substitutes. The CB3JB1R00 measures 8.00mm x 22.00mm, while PNP300JR-73-1R measures 4.60mm x 11.50mm and PNP3WVJR-73-1R measures 5.50mm x 13.00mm. Operating temperature ranges also differ: the CB3JB1R00 operates from -55°C to 275°C, whereas both YAGEO substitutes operate from -40°C to 200°C. These differences must be evaluated against specific application requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can PNP300JR-73-1R and PNP3WVJR-73-1R be used interchangeably with CB3JB1R00?

A: Both YAGEO parts match the core electrical specifications: 1 Ohm resistance, ±5% tolerance, and 3W power rating in wirewound axial configuration. However, physical dimensions and operating temperature ranges differ. Compatibility depends on whether the application can accommodate the smaller physical size and narrower temperature operating window of the YAGEO parts.

Q: What is the primary difference between PNP300JR-73-1R and PNP3WVJR-73-1R?

A: Both parts are YAGEO 1 Ohm ±5% 3W wirewound axial resistors with identical electrical specifications. The difference is physical size: PNP300JR-73-1R measures 4.60mm x 11.50mm, while PNP3WVJR-73-1R measures 5.50mm x 13.00mm. Selection between them depends on available PCB space and thermal management requirements.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. CB3JB1R00, PNP300JR-73-1R, and PNP3WVJR-73-1R are all ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: What temperature range limitations should I consider?

A: The CB3JB1R00 operates from -55°C to 275°C. Both YAGEO substitutes operate from -40°C to 200°C. If your application requires operation below -40°C or above 200°C, the YAGEO parts are not suitable substitutes.

Q: How do the physical dimensions affect PCB layout?

A: The CB3JB1R00 is larger (8.00mm x 22.00mm) than both YAGEO alternatives. PNP300JR-73-1R (4.60mm x 11.50mm) is the most compact option, while PNP3WVJR-73-1R (5.50mm x 13.00mm) offers a middle ground. Verify that your PCB layout can accommodate the selected part's footprint and lead spacing.
