Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F5494CS is determined by the following critical parameters:

Electrical Specifications: Resistance value (5.49 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 boundaries.

Mechanical Compatibility: Package type (1206 / 3216 Metric) and physical dimensions (0.126" L x 0.063" W) ensure PCB footprint compatibility. Height variation within seated maximum specifications does not affect substitution validity.

Compliance & Environmental: ROHS3 compliance, MSL rating of 1, and REACH unaffected status are baseline requirements. Additional certifications such as AEC-Q200 do not disqualify substitution but indicate enhanced qualification for specific applications.

Composition & Features: Thick film construction is the specified composition type. Moisture resistance is a documented feature of the main part; substitute parts meeting this specification are eligible.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RC3216F5494CS (Samsung Electro-Mechanics) is the specified component with active production status and documented moisture-resistant features. Use this part when Samsung supply chain and specifications are preferred.

Substitute Selection: CRCW12065M49FKEA (Vishay Dale) is a direct electrical and mechanical equivalent with identical resistance, tolerance, power rating, package, and thermal specifications. This substitute carries AEC-Q200 automotive qualification, which provides additional reliability documentation for applications requiring automotive-grade components. Both parts are ROHS3 compliant and MSL 1 rated.

Compliance Basis: Selection between these parts should be based on supply availability, lead time requirements, and application-specific certifications. The AEC-Q200 rating of the Vishay part does not restrict its use in non-automotive applications and represents an additional qualification level.

Frequently Asked Questions (FAQ)

Q: Can CRCW12065M49FKEA replace RC3216F5494CS in all applications?

A: Yes. Both parts share identical electrical specifications (5.49 MOhms ±1%, 0.25W), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), and mechanical dimensions (1206 package, 3.20mm x 1.60mm). PCB footprint compatibility is confirmed. The height difference (0.66mm vs 0.60mm seated maximum) is within acceptable tolerance for standard PCB assembly.

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

A: AEC-Q200 is an automotive industry qualification standard. The CRCW12065M49FKEA carries this certification, indicating enhanced reliability testing and documentation. This does not restrict the part to automotive use; it indicates the part meets additional qualification criteria beyond standard commercial specifications.

Q: Are there packaging differences between these parts?

A: The RC3216F5494CS is supplied in standard packaging (not specified in detail). The CRCW12065M49FKEA is supplied in Tape & Reel (TR) format. Both are 1206 package type. Packaging format affects handling and assembly processes but does not impact electrical or mechanical compatibility.

Q: Do both parts meet moisture resistance requirements?

A: Yes. Both parts are rated MSL 1 (Unlimited moisture sensitivity level), indicating no moisture sensitivity restrictions. The RC3216F5494CS explicitly documents moisture-resistant features. The CRCW12065M49FKEA meets the same MSL 1 standard.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RC3216F5494CS and CRCW12065M49FKEA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
