Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB3JB27R0 is determined by the following critical parameters:

• Resistance value: 27 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)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The substitute part PNP300JR-73-27R meets all mandatory electrical and mechanical parameters. Both components are wirewound axial resistors with identical resistance, tolerance, and power specifications. Both maintain ROHS3 compliance and feature 2-pin axial terminations suitable for through-hole PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the CB3JB27R0 and PNP300JR-73-27R are Active status components meeting identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability and lead time requirements
• Packaging format preference (Stackpole supplied in Bulk; YAGEO supplied in Cut Tape)
• Supply chain and procurement logistics
• Regulatory compliance verification for end application

Both components satisfy ROHS3, REACH, and EAR99 export control requirements. The electrical performance and physical form factor are equivalent for through-hole PCB assembly applications.

Frequently Asked Questions (FAQ)

Q: Can PNP300JR-73-27R be used as a direct replacement for CB3JB27R0?

A: Yes. Both components share identical electrical specifications (27 Ohms, ±5%, 3W) and mechanical form factor (axial through-hole). Both are wirewound resistors with equivalent regulatory compliance.

Q: Are there physical dimension differences between these parts?

A: Yes. CB3JB27R0 dimensions are 0.315" Square x 0.866" L (8.00mm x 22.00mm). PNP300JR-73-27R dimensions are 0.181" Dia x 0.453" L (4.60mm x 11.50mm). The YAGEO part is physically smaller. PCB layout and mounting hole spacing must accommodate the selected component's physical dimensions.

Q: What is the difference in operating temperature range?

A: CB3JB27R0 operates from -55°C to 275°C. PNP300JR-73-27R operates from -40°C to 200°C. For applications requiring operation below -40°C or above 200°C, the Stackpole component is required.

Q: Do both parts have the same packaging options?

A: No. CB3JB27R0 is supplied in Bulk packaging. PNP300JR-73-27R is supplied in Cut Tape (CT) packaging. Procurement and assembly processes may differ based on packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both CB3JB27R0 and PNP300JR-73-27R are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
