Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (RC0805FR-074M75L - YAGEO): This part is a direct functional equivalent to the RC2012F4754CS. All critical electrical parameters, package dimensions, and compliance certifications are identical. The temperature coefficient matches at ±100ppm/°C, and seated height is within the 0805 package envelope. This substitute is suitable for applications where the original Samsung part is unavailable and no additional automotive qualification is required.

Upgrade Option (RMCF0805FT4M75 - Stackpole Electronics Inc): This part provides AEC-Q200 automotive qualification in addition to meeting all base electrical and mechanical specifications. The temperature coefficient is ±200ppm/°C, which is acceptable for high-impedance resistor applications within the specified operating range. This substitute is appropriate for designs requiring automotive-grade components or when enhanced reliability documentation is necessary. The seated height remains within package limits.

Alternative Option (CRCW08054M75FKEA - Vishay Dale): This part meets all electrical and mechanical requirements with AEC-Q200 automotive qualification and ±100ppm/°C temperature coefficient matching the original part. The seated height of 0.020" (0.50mm) is the lowest among all options, providing additional clearance margin in space-constrained PCB layouts. This substitute is suitable for applications requiring automotive qualification with optimized height profile.

All three substitute parts maintain Active product status, RoHS3 compliance, and MSL Level 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-074M75L (YAGEO) be used as a direct replacement for RC2012F4754CS (Samsung)?

A: Yes. The RC0805FR-074M75L is a direct equivalent. Both parts share identical resistance value (4.75 MOhms), tolerance (±1%), power rating (0.125W), package (0805), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, MSL 1). The temperature coefficient and seated height are within acceptable parameters for 0805 package applications.

Q: What is the difference between the Samsung RC2012F4754CS and the Stackpole RMCF0805FT4M75?

A: The primary difference is automotive qualification. The Stackpole RMCF0805FT4M75 carries AEC-Q200 certification, while the Samsung part does not. The Stackpole part has a temperature coefficient of ±200ppm/°C compared to ±100ppm/°C for the Samsung part. All other electrical specifications and package dimensions are identical. The Stackpole part is suitable for automotive applications or designs requiring enhanced reliability documentation.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Seated heights vary slightly (0.020" to 0.026"), but all remain within the standard 0805 package envelope and are compatible with standard 0805 PCB footprints. No layout modifications are required.

Q: Which substitute part should be selected for automotive applications?

A: Both RMCF0805FT4M75 (Stackpole) and CRCW08054M75FKEA (Vishay Dale) carry AEC-Q200 automotive qualification. The Stackpole part has a ±200ppm/°C temperature coefficient, while the Vishay part matches the original ±100ppm/°C specification. Selection depends on temperature stability requirements and design specifications.

Q: Is moisture sensitivity level the same across all parts?

A: Yes. All parts, including the original RC2012F4754CS and all three substitutes, are rated MSL 1 (Unlimited). This means they have unlimited shelf life and do not require special moisture-controlled storage or baking procedures prior to assembly.

Q: Can these parts be used interchangeably in high-precision analog circuits?

A: The RC0805FR-074M75L (YAGEO) and CRCW08054M75FKEA (Vishay Dale) are preferred for high-precision applications due to their ±100ppm/°C temperature coefficient, matching the original Samsung part. The RMCF0805FT4M75 (Stackpole) with ±200ppm/°C temperature coefficient is suitable for general-purpose applications but may introduce greater temperature-dependent drift in precision circuits.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts are RoHS3 compliant, matching the compliance status of the original RC2012F4754CS. All parts are also REACH unaffected and classified as EAR99 for export control purposes.
