Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F1654CS are identified through strict matching of the following critical parameters:

Electrical Specifications: Resistance value (1.65 MOhms), tolerance (±1%), and power rating (0.25W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance equivalence.

Mechanical Compatibility: Package designation (1206 / 3216 Metric) and physical dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm) ensure PCB footprint compatibility and assembly process alignment.

Regulatory & Environmental Compliance: RoHS3 compliance and MSL 1 rating are mandatory for direct substitution. REACH status and ECCN classification must remain consistent.

Composition & Construction: Thick film construction type ensures equivalent frequency response and noise characteristics across the specified operating range.

Substitute parts meeting all these criteria are functionally interchangeable without circuit redesign or performance degradation.

Engineering Selection Recommendations

Primary Selection (RC3216F1654CS): Samsung Electro-Mechanics RC3216F1654CS is the specified component with Active product status and moisture-resistant thick film construction. This part is suitable for general industrial and consumer applications requiring standard environmental performance.

Substitute Selection (CRCW12061M65FKEA): Vishay Dale CRCW12061M65FKEA is a direct electrical and mechanical equivalent with identical resistance, tolerance, power rating, and temperature characteristics. This part carries AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade component traceability. The seated height is 0.024" (0.60mm) compared to 0.026" (0.66mm) for the Samsung part, remaining within standard PCB assembly tolerances.

Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Selection between these parts depends on supply chain availability, packaging requirements (Samsung supplied in standard packaging; Vishay supplied in Tape & Reel), and whether automotive qualification documentation is required for the end application.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M65FKEA directly replace RC3216F1654CS on existing PCBs?

A: Yes. Both parts share identical electrical specifications (1.65 MOhms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and mechanical footprint (1206 / 3216 Metric, 0.126" L x 0.063" W). The 0.002" (0.06mm) difference in seated height is within standard PCB assembly tolerances and does not affect functionality or placement.

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

A: AEC-Q200 is an automotive industry standard qualification that documents enhanced reliability testing and traceability. This certification is relevant only if the end application requires automotive-grade component documentation. For non-automotive applications, both parts perform identically.

Q: Are there packaging differences between these parts?

A: Yes. The RC3216F1654CS is supplied in standard packaging, while the CRCW12061M65FKEA is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for high-volume automated assembly. Selection depends on production volume and assembly equipment compatibility.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both RC3216F1654CS and CRCW12061M65FKEA are RoHS3 compliant, REACH unaffected, and classified as ECCN EAR99. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts, indicating no moisture bake-out requirement before soldering.

Q: What determines substitution eligibility for 1206 chip resistors?

A: Substitution eligibility is determined by: (1) identical resistance value and tolerance, (2) equal or greater power rating, (3) matching temperature coefficient and operating range, (4) identical package designation and physical dimensions, and (5) equivalent or superior compliance certifications (RoHS, REACH, ECCN). All these criteria are met between RC3216F1654CS and CRCW12061M65FKEA.
