Parameter Comparison

Engineering Selection Recommendations

RC0805FR-0717R4L (YAGEO) is the primary direct equivalent substitute. This part maintains identical electrical specifications and mechanical compatibility with the RC2012F17R4CS. Both components are Active status products with ROHS3 compliance and unlimited MSL rating. The YAGEO variant offers significantly higher inventory availability (127,703 pieces) compared to the Samsung original (933 pieces), making it suitable for high-volume production requirements.

ERJ-6ENF17R4V (Panasonic Electronic Components) and RMCF0805FT17R4 (Stackpole Electronics Inc) are qualified substitutes with identical core electrical and thermal parameters. Both parts include AEC-Q200 automotive qualification, which provides additional reliability assurance for applications subject to automotive environmental and performance standards. These options are appropriate when automotive-grade component certification is required or preferred, even for non-automotive applications.

All three substitute parts are electrically and mechanically interchangeable with the RC2012F17R4CS within the specified parameter tolerances. Selection among substitutes should be based on availability, supply chain logistics, and application-specific compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0717R4L replace RC2012F17R4CS in all applications?

A: Yes. RC0805FR-0717R4L meets all mandatory electrical and mechanical parameters: 17.4 Ohm resistance, ±1% tolerance, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance. The maximum seated height difference (0.024" vs 0.026") is within typical PCB assembly tolerances.

Q: What is the difference between the Samsung part and the Panasonic ERJ-6ENF17R4V?

A: Electrical and thermal specifications are identical. The primary difference is that ERJ-6ENF17R4V includes AEC-Q200 automotive qualification, which certifies the component for automotive applications. The maximum seated height is 0.028" (0.70mm) compared to 0.026" (0.66mm) for the Samsung part, a difference of 0.002" that does not affect standard PCB assembly.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC0805FR-0717R4L, ERJ-6ENF17R4V, and RMCF0805FT17R4 are all ROHS3 compliant, matching the environmental compliance status of the RC2012F17R4CS.

Q: What does MSL 1 (Unlimited) mean for these resistors?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture-controlled storage or handling procedures. All four parts in this comparison carry MSL 1 rating.

Q: Can I use the AEC-Q200 rated parts in non-automotive applications?

A: Yes. AEC-Q200 certification is a superset of standard reliability requirements. Parts qualified to AEC-Q200 (ERJ-6ENF17R4V and RMCF0805FT17R4) are suitable for any application requiring the specified electrical and mechanical parameters, regardless of automotive use.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: Temperature coefficient specifies how the resistance value changes with temperature. ±100ppm/°C means the resistance can drift up to 0.01% per degree Celsius across the -55°C to 155°C operating range. All substitute parts maintain this specification, ensuring consistent performance across the full temperature range.

Q: Are there any height restrictions for PCB assembly?

A: The maximum seated heights range from 0.024" (0.60mm) to 0.028" (0.70mm). Standard PCB assembly equipment accommodates this variation. If your design has specific height constraints below 0.028", verify compatibility with your assembly process specifications.
