Substitute Part Grouping Explanation

Substitute parts for the CB3JB75R0 are qualified based on the following critical parameters:

• Resistance value: 75 Ohms (exact match required)
• Tolerance: ±5% (equivalent tolerance band)
• Power rating: 3W (minimum requirement)
• Composition: Wirewound (functional requirement)
• Package: Axial (mechanical compatibility)
• Compliance: ROHS3 Compliant (regulatory requirement)

The PNP300JR-73-75R from YAGEO meets these core substitution criteria. Both parts share identical electrical specifications for resistance, tolerance, and power rating, with wirewound construction and axial packaging. Both components maintain ROHS3 compliance and are suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CB3JB75R0 and PNP300JR-73-75R are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability, lead time, and procurement requirements. The electrical and mechanical specifications are equivalent for circuit applications requiring a 75 Ohm, 3W wirewound axial resistor. Both components satisfy the same regulatory and compliance requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can PNP300JR-73-75R be used as a direct replacement for CB3JB75R0?

A: Yes. Both parts share identical resistance (75 Ohms), tolerance (±5%), power rating (3W), composition (wirewound), and axial package configuration. Electrical performance in equivalent circuits is identical.

Q: Are there differences in physical dimensions between these parts?
