RCS3216F2944CS Equivalent & Substitute Parts

Part Overview

The RCS3216F2944CS is a 2.94 MOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant construction, operating across the temperature range of -55°C to 155°C. The component is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize procurement costs, and maintain design continuity when the primary manufacturer part becomes unavailable.

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F2944CS are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Mandatory Matching Parameters:

  • Resistance value: 2.94 MOhms (exact match)
  • Tolerance: ±1% (equal or tighter tolerance acceptable)
  • Power rating: 0.25W minimum (equal or higher acceptable)
  • Package: 1206 (3216 Metric) form factor (exact match for PCB compatibility)
  • Composition: Thick film construction
  • Temperature coefficient: ±100ppm/°C (equal or better stability acceptable)
  • Operating temperature range: -55°C ~ 155°C minimum (equal or wider range acceptable)
  • RoHS compliance: ROHS3 Compliant (regulatory requirement)

The CRCW12062M94FKEA from Vishay Dale meets all mandatory parameters while adding automotive-grade AEC-Q200 qualification, which represents an enhancement rather than a deviation from the base specification.

Engineering Selection Recommendations

The CRCW12062M94FKEA from Vishay Dale is a direct electrical and mechanical substitute for the RCS3216F2944CS. Both components are active production parts with ROHS3 compliance and identical core electrical specifications.

Selection Basis:

  1. Electrical Equivalence: All critical parameters—resistance value, tolerance, power rating, temperature coefficient, and operating temperature range—are identical between the two parts.

  2. Physical Compatibility: Both components use the 1206 (3216 Metric) package with matching footprints. The Vishay part has a slightly lower seated height (0.024" vs. 0.026"), which is compatible with standard PCB assembly processes and does not create clearance issues.

  3. Regulatory Compliance: Both parts meet ROHS3 requirements and carry MSL 1 rating, ensuring equivalent handling and storage requirements.

  4. Product Status: Both components are in active production, ensuring long-term availability and supply chain stability.

  5. Qualification Differences: The Samsung part emphasizes anti-sulfur and moisture-resistant features, while the Vishay part carries automotive AEC-Q200 qualification. These represent different application focuses rather than incompatibilities. The choice between them depends on application requirements: industrial/general-purpose environments favor the Samsung part, while automotive or high-reliability applications may benefit from the Vishay AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can the CRCW12062M94FKEA replace the RCS3216F2944CS in existing designs without PCB modification?

A: Yes. Both components use identical 1206 (3216 Metric) package dimensions and footprints. The Vishay part's slightly lower seated height (0.024" vs. 0.026") is within standard PCB assembly tolerances and does not require design changes.

Q: Are the electrical characteristics identical between these two parts?

A: Yes. Resistance value (2.94 MOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) are identical. Both use thick film construction.

Q: What is the difference between the anti-sulfur/moisture-resistant feature of the Samsung part and the AEC-Q200 qualification of the Vishay part?

A: These represent different qualification approaches. The Samsung RCS3216F2944CS emphasizes environmental protection through anti-sulfur and moisture-resistant construction, suitable for general industrial applications.
