Engineering Selection Recommendations

RC0805FR-075M9L (YAGEO) is the direct equivalent substitute. All electrical parameters, mechanical dimensions, and compliance certifications are identical to the RC2012F5904CS. This part is suitable for direct replacement in any application where the Samsung component is specified. YAGEO inventory availability (7,377 units) supports high-volume procurement requirements.

CRCW08055M90FKEA (Vishay Dale) is a qualified substitute with additional automotive AEC-Q200 qualification. All core electrical specifications match the primary part. The reduced seated height (0.020" vs. 0.026") may provide advantages in space-constrained PCB layouts. This part is appropriate for applications requiring automotive-grade reliability or where AEC-Q200 certification is mandated. Vishay Dale inventory (20,939 units) provides extended supply availability.

Both substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature ranges. Selection between substitutes depends on application-specific requirements for automotive qualification and physical height constraints.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-075M9L replace RC2012F5904CS in all applications?

A: Yes. RC0805FR-075M9L meets all electrical and mechanical specifications of RC2012F5904CS. Both parts share identical resistance (5.9 MOhms), tolerance (±1%), power rating (0.125W), package (0805), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The seated height difference (0.024" vs. 0.026") is within typical PCB assembly tolerances.

Q: What is the difference between the two substitute parts?

A: RC0805FR-075M9L (YAGEO) and CRCW08055M90FKEA (Vishay Dale) are electrically identical. The primary difference is that CRCW08055M90FKEA carries AEC-Q200 automotive qualification and has a lower seated height (0.020" vs. 0.024"). Select CRCW08055M90FKEA for automotive applications or space-constrained designs.

Q: Are all three parts interchangeable on the same PCB?

A: Yes, all three parts are mechanically and electrically interchangeable. The 0805 package footprint is standardized across all three manufacturers. Seated height variations (0.020" to 0.026") do not affect PCB footprint compatibility or soldering processes.

Q: Do the substitute parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should be selected for high-volume production?

A: CRCW08055M90FKEA (Vishay Dale) offers the highest inventory availability (20,939 units) and is recommended for high-volume requirements. RC0805FR-075M9L (YAGEO) with 7,377 units in stock is suitable for medium-volume applications.

Q: Are all parts ROHS3 compliant?

A: Yes. RC2012F5904CS, RC0805FR-075M9L, and CRCW08055M90FKEA are all ROHS3 compliant and REACH unaffected.
