Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB5JB12R0 is determined by strict equivalence in the following parameters: resistance value (12 Ohms), tolerance (±5%), power rating (5W), composition (wirewound), and package configuration (axial). The substitute part PNP5WVJT-73-12R from YAGEO meets these core electrical and mechanical requirements. Both parts are ROHS3 compliant and maintain the same termination count (2). Substitution is valid when all specified electrical parameters match and the physical package remains axial configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the CB5JB12R0 and PNP5WVJT-73-12R are Active status components with full ROHS3 compliance and REACH unaffected designation. Selection between these parts is based on availability, packaging format preference, and thermal operating range requirements. The CB5JB12R0 operates across -55°C to 275°C with ±200ppm/°C temperature coefficient. The PNP5WVJT-73-12R operates across -40°C to 200°C. For applications requiring the full -55°C lower temperature limit or sustained operation above 200°C, the CB5JB12R0 is the appropriate selection. For standard industrial applications within -40°C to 200°C, the PNP5WVJT-73-12R provides equivalent electrical performance with alternative packaging (Cut Tape versus Tray).

Frequently Asked Questions (FAQ)

Q: Can PNP5WVJT-73-12R replace CB5JB12R0 in all applications?

A: Substitution is valid for applications operating within -40°C to 200°C. Applications requiring operation below -40°C or above 200°C must use the CB5JB12R0 to maintain specified performance within the full operating temperature range.

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

A: CB5JB12R0 dimensions are 0.374" Square x 0.866" L (9.50mm x 22.00mm). PNP5WVJT-73-12R dimensions are 0.295" Dia x 0.669" L (7.50mm x 17.00mm). Both maintain axial package configuration with identical electrical specifications.

Q: Are both parts suitable for moisture-sensitive applications?

A: Both parts have Moisture Sensitivity Level (MSL) listed as Not Applicable, indicating neither part requires special moisture handling during storage or assembly.

Q: Do packaging format differences affect electrical performance?

A: No. Packaging format (Tray versus Cut Tape) affects logistics and assembly processes only. Electrical performance, resistance value, tolerance, power rating, and composition remain identical.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both CB5JB12R0 and PNP5WVJT-73-12R are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
