Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F4534CS is determined by the following critical parameters:

Electrical Specifications: Resistance value (4.53 MOhms), tolerance (±1%), and power rating (0.25W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must match or exceed the original specification.

Mechanical Compatibility: Package type (1206 / 3216 Metric), physical dimensions (0.126" L x 0.063" W), and termination count (2) must be identical to ensure PCB footprint compatibility.

Compliance & Environmental: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are required. REACH status and ECCN classification must align with the original part.

Composition & Construction: Thick film construction is the specified technology. Features such as anti-sulfur and moisture resistance are desirable but not mandatory for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The CRCW12064M53FKEA (Vishay Dale) is a direct electrical and mechanical equivalent to the RCS3216F4534CS. Both parts meet identical specifications for resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Physical dimensions and package footprint are identical, ensuring direct PCB compatibility.

Both parts are ROHS3 compliant, carry Moisture Sensitivity Level 1 (Unlimited), and share identical REACH and ECCN classifications. Both maintain active production status.

The CRCW12064M53FKEA carries AEC-Q200 automotive qualification, which represents an additional certification tier beyond the base specification. This qualification does not conflict with the original part's requirements and may provide enhanced reliability documentation for applications requiring automotive-grade components.

The seated height difference (0.026" vs 0.024") is within typical PCB assembly tolerances and does not impact functional compatibility or board layout.

Frequently Asked Questions (FAQ)

Q: Can CRCW12064M53FKEA replace RCS3216F4534CS in all applications?

A: Yes. Both parts share identical electrical specifications (4.53 MOhms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and mechanical dimensions (1206 package, 0.126" L x 0.063" W). PCB footprint compatibility is guaranteed.

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

A: AEC-Q200 is an automotive industry qualification standard. The CRCW12064M53FKEA meets this additional certification, which does not restrict its use in non-automotive applications. It indicates enhanced reliability testing and documentation.

Q: Are there packaging differences between these parts?

A: The RCS3216F4534CS is specified with standard packaging notation. The CRCW12064M53FKEA is available in Tape & Reel (TR) format. Both use identical 1206 (3216 Metric) component packages. Tape & Reel packaging is standard for automated assembly processes.

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

A: Yes. Both parts are ROHS3 compliant, carry Moisture Sensitivity Level 1 (Unlimited), and are REACH Unaffected. Both share EAR99 ECCN classification.

Q: Is the 0.002" seated height difference significant?

A: No. The height difference (0.026" vs 0.024") falls within standard PCB assembly tolerances and does not affect component placement, solder joint formation, or functional performance.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical specifications, temperature characteristics, package dimensions, and compliance certifications ensure direct interchangeability without design modification.
