Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB3JB9R10 is determined by the following critical parameters:

• Resistance value: 9.1 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)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification

The substitute part PNP300JR-73-9R1 meets all critical electrical and mechanical parameters. Both parts are wirewound axial resistors with identical resistance, tolerance, and power specifications. Both maintain ROHS3 compliance and equivalent regulatory status.

Parameter Comparison

Engineering Selection Recommendations

Both CB3JB9R10 and PNP300JR-73-9R1 are active production components with ROHS3 compliance and equivalent regulatory classification. Selection between these parts depends on application-specific requirements:

The CB3JB9R10 supports the full operating temperature range of -55°C to 275°C and features flame-proof construction. The PNP300JR-73-9R1 operates within -40°C to 200°C and includes flame-retardant coating. Physical dimensions differ significantly, with the CB3JB9R10 measuring 8.00mm x 22.00mm and the PNP300JR-73-9R1 measuring 4.60mm x 11.50mm. PCB layout and thermal management considerations must account for these dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can PNP300JR-73-9R1 replace CB3JB9R10 in all applications?

A: Electrical substitution is valid for applications operating within -40°C to 200°C. Applications requiring operation below -40°C or above 200°C require the CB3JB9R10. Physical dimensions differ; PCB layout compatibility must be verified.

Q: What are the key differences between these parts?

A: Both parts share identical resistance (9.1 Ohms), tolerance (±5%), power rating (3W), and wirewound composition. Operating temperature ranges differ: CB3JB9R10 spans -55°C to 275°C while PNP300JR-73-9R1 spans -40°C to 200°C. Physical dimensions are substantially different, requiring layout verification.

Q: Are both parts RoHS compliant?

A: Yes. Both CB3JB9R10 and PNP300JR-73-9R1 are ROHS3 compliant and REACH unaffected.

Q: Does package type differ between these parts?

A: Both parts use axial through-hole packaging. However, physical dimensions differ significantly. The CB3JB9R10 is 8.00mm x 22.00mm; the PNP300JR-73-9R1 is 4.60mm x 11.50mm. PCB hole spacing and component clearance must be verified before substitution.

Q: Which part should be selected for high-temperature applications?

A: The CB3JB9R10 supports operation to 275°C and is the appropriate choice for high-temperature applications. The PNP300JR-73-9R1 maximum operating temperature is 200°C.
