Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F4224CS is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 4.22 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The CRCW12064M22FKEA from Vishay Dale meets all critical electrical specifications and mechanical dimensions required for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Compliance certifications (ROHS3, REACH Unaffected) are equivalent across both components.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F4224CS and CRCW12064M22FKEA are active production components with full ROHS3 compliance and REACH unaffected status. The CRCW12064M22FKEA carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The seated height difference of 0.002" (0.06mm) between the two parts is negligible for standard PCB assembly processes and does not impact circuit performance or board layout compatibility. Both components are available in high inventory quantities, supporting production continuity and supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: Can the CRCW12064M22FKEA directly replace the RCS3216F4224CS in existing designs?

A: Yes. Both components share identical electrical specifications (4.22 MOhms ±1%, 0.25W), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), and mechanical dimensions (1206 package, 3.20mm x 1.60mm). The maximum seated height difference of 0.002" is within standard PCB assembly tolerances and does not affect circuit functionality or board layout.

Q: Are there compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The CRCW12064M22FKEA includes AEC-Q200 automotive qualification, which is an additional certification not specified for the RCS3216F4224CS. This qualification indicates enhanced reliability testing and is suitable for automotive and high-reliability applications.

Q: What is the moisture sensitivity level for both parts?

A: Both the RCS3216F4224CS and CRCW12064M22FKEA have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly.

Q: Are the package types identical?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm) dimensions. The components are mechanically interchangeable on standard PCB layouts designed for 1206 resistors.

Q: What is the composition of these resistors?

A: Both components are thick film chip resistors with identical construction. The RCS3216F4224CS features anti-sulfur and moisture-resistant properties, while the CRCW12064M22FKEA is specified for automotive AEC-Q200 applications.
