Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F5494CS are qualified based on the following critical parameters:

Electrical Equivalence: Resistance value of 5.49 MOhms with ±1% tolerance and 0.25W power rating must be maintained.

Package Compatibility: 1206 (3216 Metric) package with identical footprint dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm) ensures direct PCB placement compatibility.

Environmental Performance: Operating temperature range of -55°C to 155°C and temperature coefficient of ±100ppm/°C define thermal performance boundaries.

Composition and Construction: Thick film construction maintains electrical and thermal characteristics consistent with the original specification.

Compliance Requirements: ROHS3 compliance and MSL 1 rating ensure regulatory and manufacturing process compatibility.

The CRCW12065M49FKEA from Vishay Dale meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can CRCW12065M49FKEA replace RCS3216F5494CS in existing designs?

A: Yes. Both parts share identical resistance value (5.49 MOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The maximum seated height difference (0.66mm vs 0.60mm) is within typical PCB assembly tolerances.

Q: What is the significance of AEC-Q200 qualification on the Vishay part?

A: AEC-Q200 is an automotive industry standard qualification that certifies enhanced reliability through defined stress testing and performance validation. This qualification is relevant only if the application requires automotive-grade components.

Q: Are there packaging differences between these parts?

A: The RCS3216F5494CS packaging is not specified in the provided data. The CRCW12065M49FKEA is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly process.

Q: Do both parts meet RoHS and REACH requirements?

A: Yes. Both the RCS3216F5494CS and CRCW12065M49FKEA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the difference between anti-sulfur construction and standard thick film?

A: Anti-sulfur construction on the Samsung part provides enhanced resistance to sulfur-containing environmental contaminants. Both parts are thick film resistors with identical electrical performance; the anti-sulfur feature is an additional protective characteristic of the Samsung design.
