Engineering Selection Recommendations
Direct Equivalent (Same Specifications): RNCF0805DTE23K7 from Stackpole Electronics Inc is the direct equivalent with identical electrical specifications and AEC-Q200 automotive qualification. This part offers improved temperature coefficient performance (±25ppm/°C vs ±50ppm/°C) while maintaining ±0.5% tolerance and 0.25W power rating. Inventory availability is significantly higher at 10,184 units.
Automotive-Qualified Alternatives: ERA-6AEB2372V (Panasonic) maintains AEC-Q200 certification with tighter ±0.1% tolerance and improved ±25ppm/°C temperature coefficient. Power rating is reduced to 0.125W (1/8W), suitable for applications not requiring full 0.25W dissipation. Highest inventory availability at 19,039 units.
General Industrial Substitutes: TE Connectivity 3-2176093-9 provides ±0.1% tolerance with 0.25W power rating and ±25ppm/°C temperature coefficient. YAGEO RT0805BRD0723K7L and Bourns CRT0805-BZ-2372ELF offer ±0.1% tolerance at 0.125W power rating with full -55°C to 155°C operating range. Bourns part includes current sense feature.
Lower Power Rating Alternatives: CPF0805B23K7E1 and RN73C2A23K7BTDF both rated at 0.1W (1/10W) with ±0.1% tolerance. RN73C2A23K7BTDF provides superior ±10ppm/°C temperature coefficient. These are suitable only for applications with power dissipation below 0.1W.
Temperature Range Limitation: RR1220P-2372-D-M from Susumu operates only to 125°C maximum (vs 155°C standard). This part is suitable only for applications with maximum operating temperature not exceeding 125°C.
Frequently Asked Questions (FAQ)
Q: Can I substitute RNCF0805DTC23K7 with a lower tolerance part like ±0.1%? A: Yes. Lower tolerance (tighter) specifications are acceptable substitutes. Parts with ±0.1% tolerance such as 3-2176093-9, CPF0805B23K7E1, ERA-6AEB2372V, RN73C2A23K7BTDF, RT0805BRD0723K7L, and CRT0805-BZ-2372ELF all meet this criterion while maintaining the 23.7 kOhms resistance value and 0805 package.
Q: What is the impact of using a lower power-rated substitute? A: Power rating reduction is permissible only if your application's actual power dissipation is below the substitute part's rating. For example, CPF0805B23K7E1 and RN73C2A23K7BTDF rated at 0.1W can replace the 0.25W original only if circuit power dissipation does not exceed 0.1W. Exceeding the power rating causes component failure.
Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance as specified in the input data.
Q: Can I use RR1220P-2372-D-M if my application operates at 150°C? A: No. RR1220P-2372-D-M has a maximum operating temperature of 125°C. For applications requiring 155°C operation, use RNCF0805DTE23K7, 3-2176093-9, ERA-6AEB2372V, RN73C2A23K7BTDF, RT0805BRD0723K7L, or CRT0805-BZ-2372ELF.
Q: What is the difference between AEC-Q200 rated and non-rated parts? A: AEC-Q200 certification indicates automotive-grade qualification. RNCF0805DTC23K7, RNCF0805DTE23K7, and ERA-6AEB2372V carry this certification. Non-certified parts are suitable for industrial and consumer applications but should not be used in automotive designs requiring AEC-Q200 compliance.
Q: Does the Bourns CRT0805-BZ-2372ELF "current sense" feature affect substitution? A: The current sense feature is an additional capability that does not prevent substitution. CRT0805-BZ-2372ELF functions as a standard 23.7 kOhms resistor in any application. The current sense feature is available if needed but is not required for basic resistor functionality.
Q: Can I mix different substitute parts in the same circuit? A: Yes, provided each part meets the electrical requirements of its specific circuit location. Mixing parts with different tolerances, temperature coefficients, or power ratings is acceptable as long as each location's requirements are satisfied.
