Substitute Part Grouping Explanation

Substitution eligibility for the CB3JB22R0 is determined by the following critical parameters:

• Resistance value: 22 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)
• Regulatory compliance: ROHS3 and REACH status alignment

The substitute part PNP300JR-73-22R meets all core electrical specifications and maintains equivalent regulatory compliance. Mechanical dimensions and operating temperature ranges may vary within acceptable limits for axial wirewound resistor applications.

Parameter Comparison

Engineering Selection Recommendations

Both CB3JB22R0 and PNP300JR-73-22R are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

The CB3JB22R0 supports an extended operating temperature range of -55°C to 275°C with a specified temperature coefficient of ±200ppm/°C. The PNP300JR-73-22R operates within -40°C to 200°C with unspecified temperature coefficient characteristics. Both parts are wirewound axial resistors with identical electrical ratings of 22 Ohms at ±5% tolerance and 3W power dissipation.

Mechanical dimensions differ between the two parts. The CB3JB22R0 measures 8.00mm x 22.00mm, while the PNP300JR-73-22R measures 4.60mm x 11.50mm. PCB layout and thermal management considerations may influence part selection based on available board space and heat dissipation requirements.

Frequently Asked Questions (FAQ)

Q: Can PNP300JR-73-22R replace CB3JB22R0 in all applications?

A: Electrical substitution is valid for applications operating within -40°C to 200°C. Applications requiring the extended temperature range of -55°C to 275°C must retain the CB3JB22R0. Verify PCB layout compatibility due to dimensional differences.

Q: What are the key differences between these parts?

A: Both parts share identical resistance (22 Ohms), tolerance (±5%), power rating (3W), and wirewound composition. Operating temperature ranges and physical dimensions differ. The CB3JB22R0 is larger with extended temperature capability; the PNP300JR-73-22R is more compact.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both CB3JB22R0 and PNP300JR-73-22R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: How do the axial package dimensions affect PCB design?

A: The CB3JB22R0 (8.00mm x 22.00mm) requires more board space than the PNP300JR-73-22R (4.60mm x 11.50mm). Verify hole spacing and component clearance on your PCB layout before substitution.

Q: What is the temperature coefficient significance?

A: The CB3JB22R0 specifies ±200ppm/°C temperature coefficient. The PNP300JR-73-22R does not provide this specification. For precision applications with tight tolerance requirements across temperature ranges, verify temperature coefficient performance with the manufacturer.
