Frequently Asked Questions (FAQ)

Q: Can RCWE1206R180FKEA be used as a direct replacement for CSR1206FKR180?

A: Yes. Both parts share identical resistance (180 mOhms), tolerance (±1%), power rating (0.5W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Physical dimensions are within acceptable 1206 package tolerances.

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

A: The RCWE1206R180FKEA is slightly larger: 0.122" L × 0.063" W × 0.028" H (max) compared to CSR1206FKR180 at 0.120" L × 0.061" W × 0.026" H (max). These variations fall within standard 1206 (3216 Metric) package specifications and do not affect PCB layout compatibility.

Q: Does the RCWE1206R180FKEA offer any additional benefits?

A: The RCWE1206R180FKEA includes AEC-Q200 automotive qualification and moisture-resistant construction. These features provide enhanced reliability for automotive and high-humidity applications while maintaining identical electrical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both CSR1206FKR180 and RCWE1206R180FKEA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the temperature coefficient significance for these parts?

A: Both parts have a temperature coefficient of ±100ppm/°C, ensuring stable resistance performance across the -55°C to 155°C operating range. This specification is critical for precision current sensing applications where resistance drift must be minimized.
