Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB3JB15R0 is determined by the following critical parameters:

• Resistance value: 15 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 Compliant (minimum requirement)

The PNP300JR-73-15R from YAGEO meets all mandatory electrical and mechanical criteria for direct substitution. Both components share identical resistance, tolerance, power rating, composition, and package configuration. Both maintain ROHS3 compliance and are suitable for equivalent circuit applications.

Engineering Selection Recommendations

Both the CB3JB15R0 and PNP300JR-73-15R are Active status components with full ROHS3 and REACH compliance. Selection between these parts should be based on application operating temperature requirements. The CB3JB15R0 supports an extended upper temperature limit of 275°C compared to the PNP300JR-73-15R at 200°C. For applications operating within the -40°C to 200°C range, either component is functionally equivalent. For applications requiring operation above 200°C, the CB3JB15R0 is the appropriate selection. Both components are suitable for direct PCB substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the PNP300JR-73-15R replace the CB3JB15R0 in all applications?

A: The PNP300JR-73-15R is electrically and mechanically equivalent for applications operating within -40°C to 200°C. Applications requiring operation above 200°C must use the CB3JB15R0 due to its extended temperature rating of 275°C.

Q: Are there physical dimension differences between these parts?

A: Yes. The CB3JB15R0 measures 0.315" Square x 0.866" L (8.00mm x 22.00mm). The PNP300JR-73-15R measures 0.181" Dia x 0.453" L (4.60mm x 11.50mm). The PNP300JR-73-15R is physically smaller. Verify PCB layout clearances before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the CB3JB15R0 and PNP300JR-73-15R are ROHS3 Compliant and REACH Unaffected, meeting equivalent regulatory standards.

Q: What is the difference between "Flame Proof" and "Flame Retardant Coating"?

A: Both designations indicate fire safety features. The CB3JB15R0 specifies Flame Proof construction, while the PNP300JR-73-15R specifies Flame Retardant Coating. Both are safety-rated components suitable for applications requiring flame protection.

Q: Which part should be selected for new designs?

A: Selection depends on application temperature requirements and PCB space constraints. For standard operating ranges (-40°C to 200°C) with space limitations, the PNP300JR-73-15R is suitable. For extended temperature applications or where the larger form factor is acceptable, the CB3JB15R0 is appropriate.
