Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F5231CS is determined by strict equivalence across the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance: 5.23 kOhms
• Tolerance: ±1%
• Power Rating: 0.25W minimum
• Package: 1206 (3216 Metric)
• Composition: Thick Film

Important Parameters (Must Match or Be Compatible):

• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C minimum
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

All substitute parts listed meet these criteria. Differences in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. bulk), and additional certifications (such as AEC-Q200) do not disqualify substitution but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-075K23L (YAGEO) is the primary direct substitute. It maintains Active product status, matches all critical and important parameters, and offers significantly higher inventory availability (19990 pieces). This part is suitable for general industrial and commercial applications requiring standard thick film resistor performance.

CRCW12065K23FKEA (Vishay Dale) is the recommended substitute for applications requiring automotive-grade components. This part carries AEC-Q200 certification, indicating qualification for automotive environments. It maintains Active product status and all electrical specifications. Selection of this part is appropriate when automotive reliability standards or supply chain requirements mandate AEC-Q200 qualification.

ERJ-8ENF5231V (Panasonic Electronic Components) carries AEC-Q200 certification and offers the highest inventory availability (41175 pieces). However, this part is designated "Not For New Designs," indicating end-of-life status. This part is suitable only for replacement, repair, or legacy system applications where continued use of existing designs is required. New designs should not incorporate this part.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-075K23L replace RC3216F5231CS in any application?

A: Yes. RC1206FR-075K23L is electrically and mechanically equivalent. Both parts share identical resistance (5.23 kOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Physical dimensions vary slightly within 1206 specification tolerances but do not affect PCB compatibility.

Q: What is the difference between the Samsung and YAGEO parts?

A: The RC3216F5231CS (Samsung) and RC1206FR-075K23L (YAGEO) are functionally identical. Differences are limited to manufacturer identity, packaging format (Samsung uses standard packaging; YAGEO uses Tape & Reel), and minor dimensional variations within 1206 specification. Both are Active products with equivalent performance characteristics.

Q: When should I use CRCW12065K23FKEA instead of the standard parts?

A: Use CRCW12065K23FKEA when your application or supply chain requires AEC-Q200 automotive qualification. This certification indicates the part meets automotive reliability and environmental stress testing standards. If your design does not require automotive qualification, standard parts (Samsung or YAGEO) are functionally equivalent and may offer cost or availability advantages.

Q: Why is ERJ-8ENF5231V marked "Not For New Designs"?

A: "Not For New Designs" indicates the part is in end-of-life status. Panasonic continues to supply existing inventory but does not recommend this part for new product development. Use ERJ-8ENF5231V only for replacement or repair of existing systems. For new designs, select RC1206FR-075K23L (YAGEO) or CRCW12065K23FKEA (Vishay Dale).

Q: Are all these parts RoHS3 compliant?

A: Yes. All listed parts (RC3216F5231CS, RC1206FR-075K23L, CRCW12065K23FKEA, and ERJ-8ENF5231V) are ROHS3 Compliant and REACH Unaffected. They are suitable for applications subject to RoHS and REACH regulatory requirements.

Q: What is MSL 1 (Unlimited) and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates the part has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry MSL 1 rating, meaning they can be stored under standard conditions without desiccant packaging or time-limited shelf life restrictions.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, within the constraints of your specific PCB design. All parts are 1206 package and electrically equivalent. Minor physical dimension differences (length 3.10mm to 3.20mm, height 0.60mm to 0.70mm) fall within 1206 specification tolerances and do not affect PCB footprint compatibility. Verify your PCB design accommodates the maximum dimensions of the substitute part.
