Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB2JB39R0 is determined by the following critical parameters:

• Resistance value: 39 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Regulatory compliance: ROHS3 Compliant (minimum requirement)

The substitute part PNP200JR-52-39R meets all core electrical and mechanical specifications. Both parts are wirewound axial resistors with identical resistance, tolerance, and power ratings. Both maintain ROHS3 compliance and are suitable for direct substitution in applications where the specified parameters are required.

Parameter Comparison

Engineering Selection Recommendations

Both CB2JB39R0 and PNP200JR-52-39R are active production components with full regulatory compliance. Selection between these parts should be based on application-specific operating temperature requirements. The CB2JB39R0 supports an extended operating temperature range of -55°C to 275°C, while the PNP200JR-52-39R operates within -40°C to 200°C. For applications requiring operation below -40°C or above 200°C, the CB2JB39R0 is the appropriate choice. Both parts maintain identical electrical specifications and are suitable for direct board-level substitution where temperature constraints are satisfied.

Frequently Asked Questions (FAQ)

Q: Can PNP200JR-52-39R replace CB2JB39R0 in all applications?

A: Direct substitution is valid for applications operating within the -40°C to 200°C temperature range. Applications requiring operation outside this range require the CB2JB39R0 due to its extended temperature capability.

Q: Are the physical dimensions compatible between these parts?

A: Both parts are axial package resistors. The CB2JB39R0 measures 0.252" square x 0.709" L (6.40mm x 18.00mm), while the PNP200JR-52-39R measures 0.138" Dia x 0.354" L (4.60mm x 9.00mm). Physical board layout must accommodate the dimensional differences.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CB2JB39R0 and PNP200JR-52-39R are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards.

Q: What is the difference between flame-proof and flame-retardant coating?

A: The CB2JB39R0 features flame-proof construction, while the PNP200JR-52-39R uses flame-retardant coating. Both provide safety characteristics; the specific requirement depends on application standards and safety certifications.

Q: Are the electrical specifications identical?

A: Yes. Both parts provide 39 Ohms ±5% at 2W with wirewound composition, ensuring equivalent electrical performance in circuit applications.
