Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F2R4CS are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

Electrical Parameters (Must Match):

• Resistance value: 2.4 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package / Case: 1206 (3216 Metric)
• Number of terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters (Must Match):

• RoHS3 Compliant status
• REACH Unaffected status

The identified substitute parts RC1206FR-072R4L (YAGEO) and RMCF1206FT2R40 (Stackpole Electronics Inc) satisfy all mandatory electrical, mechanical, and compliance requirements. Temperature coefficient variations (±200ppm/°C versus ±300ppm/°C) and dimensional tolerances within the 1206 package specification do not preclude substitution. The RMCF1206FT2R40 includes additional AEC-Q200 automotive qualification, which represents an enhancement rather than a limitation for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-072R4L (YAGEO) is a direct functional equivalent suitable for applications requiring standard moisture-resistant thick film construction. This part maintains identical electrical specifications and RoHS3 compliance. The temperature coefficient of ±200ppm/°C represents improved thermal stability compared to the primary part. Dimensional variation in length (3.10mm versus 3.20mm) remains within 1206 package tolerance specifications and does not affect PCB layout compatibility.

RMCF1206FT2R40 (Stackpole Electronics Inc) is qualified for applications requiring automotive-grade reliability through AEC-Q200 certification. This part satisfies all electrical and mechanical requirements of the RC3216F2R4CS while providing enhanced qualification for automotive and high-reliability environments. The maximum seated height of 0.70mm (versus 0.65mm) must be verified against specific PCB clearance requirements, though this remains within standard 1206 package specifications.

Both substitute parts are Active status components with full RoHS3 and REACH compliance, ensuring regulatory alignment with the primary part.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-072R4L replace RC3216F2R4CS in all applications?

A: Yes. Both parts share identical resistance value (2.4 Ohms), tolerance (±1%), power rating (0.25W), package format (1206), composition (thick film), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, REACH). The temperature coefficient difference (±200ppm/°C versus ±300ppm/°C) represents improved performance. Dimensional variation in length (3.10mm versus 3.20mm) is within 1206 package specification tolerance.

Q: Is RMCF1206FT2R40 suitable for non-automotive applications?

A: Yes. AEC-Q200 automotive qualification is a superset of standard thick film resistor requirements. The RMCF1206FT2R40 meets all electrical and mechanical specifications of the RC3216F2R4CS and is suitable for general-purpose, industrial, and consumer applications. The maximum seated height of 0.70mm must be confirmed against PCB design clearance specifications.

Q: What is the significance of temperature coefficient differences?

A: The RC3216F2R4CS specifies ±300ppm/°C while both substitute parts specify ±200ppm/°C. Lower temperature coefficient indicates reduced resistance variation across the operating temperature range. This represents improved performance and does not restrict substitution; applications designed for ±300ppm/°C tolerance will operate within specification with ±200ppm/°C parts.

Q: Are packaging formats (Tape & Reel) compatible with the original part?

A: The substitute parts are supplied in Tape & Reel (TR) packaging format, which is standard for automated assembly processes. This packaging format is compatible with standard pick-and-place equipment and does not affect component electrical or mechanical performance. Verify packaging compatibility with your assembly process requirements.

Q: Do all three parts have identical moisture sensitivity ratings?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are RoHS3 Compliant and REACH Unaffected. These certifications ensure regulatory compliance for applications in regulated markets and industries.
