Substitute Part Grouping Explanation

Substitution of the RC2012F3R0CS is permissible with parts that maintain identical electrical specifications: 3 Ohms resistance, ±1% tolerance, and 0.125W power rating. All substitute candidates must operate within the -55°C to 155°C temperature range and be packaged in 0805 (2012 Metric) format with Tape & Reel delivery. Physical dimensions must remain compatible with 0.079" L x 0.049" W footprint requirements. RoHS3 compliance and MSL 1 rating are mandatory for substitution eligibility. Temperature coefficient variation (±200ppm/°C versus ±300ppm/°C) and additional certifications such as AEC-Q200 automotive qualification do not preclude substitution but represent enhanced performance characteristics for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full RoHS3 compliance, ensuring long-term availability and regulatory conformance. The RC0805FR-073RL (YAGEO) offers improved temperature coefficient performance at ±200ppm/°C compared to the original RC2012F3R0CS specification of ±300ppm/°C, with marginally reduced seated height of 0.024" (0.60mm) versus 0.026" (0.65mm). This part is suitable for applications where tighter temperature stability is required without automotive qualification demands.

The RMCF0805FT3R00 (Stackpole Electronics Inc) provides AEC-Q200 automotive qualification, making it the appropriate selection for automotive and harsh-environment applications. This part maintains the same seated height as the original part at 0.026" (0.65mm) and delivers the enhanced ±200ppm/°C temperature coefficient. AEC-Q200 certification indicates compliance with automotive reliability and quality standards.

Selection between substitute parts depends on application-specific requirements: general industrial applications may use either YAGEO or Stackpole parts; automotive applications require the RMCF0805FT3R00; applications with stringent temperature stability requirements benefit from either substitute option due to superior temperature coefficient performance.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-073RL (YAGEO) be used as a direct replacement for RC2012F3R0CS (Samsung)?

A: Yes. Both parts share identical electrical specifications (3 Ohms, ±1%, 0.125W), operate across the same temperature range (-55°C to 155°C), and are packaged in 0805 (2012 Metric) format with Tape & Reel delivery. The YAGEO part features improved temperature coefficient performance (±200ppm/°C) and is physically compatible with a maximum seated height of 0.024" (0.60mm).

Q: What is the primary difference between RMCF0805FT3R00 and the other substitutes?

A: The RMCF0805FT3R00 carries AEC-Q200 automotive qualification, designating it for automotive and mission-critical applications. All three parts are electrically equivalent, but the Stackpole part meets additional automotive reliability standards. The RMCF0805FT3R00 maintains the same seated height as the original Samsung part at 0.026" (0.65mm).

Q: Are there any physical compatibility concerns when substituting these parts?

A: All substitute parts maintain the 0805 (2012 Metric) package footprint of 0.079" L x 0.049" W. The RC0805FR-073RL has a maximum seated height of 0.024" (0.60mm), which is 0.002" lower than the original and substitute Stackpole part. This minor height difference does not affect PCB assembly compatibility but may be relevant in space-constrained applications.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. The RC0805FR-073RL (YAGEO) and RMCF0805FT3R00 (Stackpole Electronics Inc) are both ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC2012F3R0CS specification.

Q: Which substitute part should be selected for improved temperature stability?

A: Both RC0805FR-073RL (YAGEO) and RMCF0805FT3R00 (Stackpole) offer ±200ppm/°C temperature coefficient, compared to the original ±300ppm/°C specification. For general industrial applications, the YAGEO part is appropriate. For automotive applications, the Stackpole RMCF0805FT3R00 is required due to AEC-Q200 qualification.

Q: Are these parts available in equivalent quantities for production use?

A: Inventory levels vary by supplier. The RC0805FR-073RL (YAGEO) has 457,850 pieces in stock, the RMCF0805FT3R00 (Stackpole) has 17,852 pieces, and the original RC2012F3R0CS (Samsung) has 927 pieces available. Substitute selection may be influenced by production volume requirements and supply chain considerations.
