Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB3JB5R60 is determined by the following critical parameters:

• Resistance value: 5.6 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 and REACH Unaffected status

The substitute part PNP300JR-73-5R6 from YAGEO meets all core electrical and mechanical requirements. Both parts share identical resistance, tolerance, power rating, composition, and package configuration. Both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the CB3JB5R60 and PNP300JR-73-5R6 are active production components with equivalent electrical and mechanical specifications. Selection between these parts may be based on:

• Availability and lead time from respective suppliers
• Packaging format preference (Bulk versus Cut Tape)
• Inventory requirements and stock levels
• Established supply chain relationships with Stackpole Electronics or YAGEO

Both parts maintain identical regulatory compliance status (ROHS3 Compliant, REACH Unaffected, EAR99 classification) and are suitable for equivalent circuit applications.

Frequently Asked Questions (FAQ)

Q: Can PNP300JR-73-5R6 be used as a direct replacement for CB3JB5R60?

A: Yes. Both parts share identical electrical specifications (5.6 Ohms, ±5% tolerance, 3W power rating) and mechanical configuration (axial wirewound package with 2 terminations). Regulatory compliance is equivalent across both components.

Q: What are the physical dimension differences between these parts?

A: CB3JB5R60 measures 0.315" Square x 0.866" L (8.00mm x 22.00mm). PNP300JR-73-5R6 measures 0.181" Dia x 0.453" L (4.60mm x 11.50mm). The YAGEO part is physically smaller. PCB layout and mounting clearance must be verified for your specific application.

Q: Are there differences in operating temperature ranges?

A: CB3JB5R60 operates from -55°C to 275°C. PNP300JR-73-5R6 operates from -40°C to 200°C. If your application requires operation below -40°C or above 200°C, the CB3JB5R60 is the appropriate choice.

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

A: CB3JB5R60 features flame-proof construction. PNP300JR-73-5R6 features flame-retardant coating. Both are safety-rated wirewound designs. Application safety requirements determine which feature set is necessary.

Q: Do packaging differences affect substitution?

A: CB3JB5R60 is supplied in Bulk packaging. PNP300JR-73-5R6 is supplied in Cut Tape (CT) format. Electrical and mechanical performance are identical. Packaging choice depends on assembly process requirements and inventory management practices.
