Engineering Selection Recommendations
Both CB3JB47R0 and PNP300JR-73-47R are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application operating temperature requirements. The CB3JB47R0 supports an extended upper temperature limit of 275°C compared to the PNP300JR-73-47R at 200°C. For applications operating within the -40°C to 200°C range, both parts are functionally equivalent. For applications requiring operation above 200°C, the CB3JB47R0 is the appropriate selection.
Frequently Asked Questions (FAQ)
Q: Can PNP300JR-73-47R replace CB3JB47R0 in all applications?
A: PNP300JR-73-47R is electrically equivalent for applications operating within -40°C to 200°C. Applications requiring operation above 200°C must use CB3JB47R0 due to its extended temperature rating to 275°C.
Q: Are the physical dimensions compatible between these parts?
A: Both parts use axial through-hole packaging. CB3JB47R0 dimensions are 0.315" Square x 0.866" L (8.00mm x 22.00mm). PNP300JR-73-47R dimensions are 0.181" Dia x 0.453" L (4.60mm x 11.50mm). Physical layout differences must be evaluated for PCB mounting compatibility.
Q: Do both parts meet the same regulatory requirements?
A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
Q: What is the tolerance specification for these resistors?
A: Both parts maintain ±5% tolerance on the 47 Ohm resistance value.
