Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1244CS is determined by the following critical parameters:

Electrical Specifications: Resistance value (1.24 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) must match to ensure PCB footprint compatibility and assembly process alignment.

Compliance & Certifications: RoHS3 compliance and MSL 1 rating are mandatory for environmental and handling requirements. REACH and ECCN classifications must remain consistent.

Composition & Construction: Thick film construction type must be maintained. Feature sets (anti-sulfur, moisture-resistant, or automotive-grade certifications) may vary based on application requirements.

The CRCW12061M24FKEA from Vishay Dale meets all electrical and mechanical substitution criteria while introducing automotive AEC-Q200 certification as an additional qualification level.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (RCS3216F1244CS): Samsung Electro-Mechanics RCS series resistor with anti-sulfur and moisture-resistant features. Active product status with full ROHS3 and REACH compliance. Suitable for general industrial and consumer applications requiring standard thick film performance.

Substitute Part (CRCW12061M24FKEA): Vishay Dale CRCW series resistor with automotive AEC-Q200 qualification. Active product status with identical ROHS3 and REACH compliance. The AEC-Q200 certification indicates qualification for automotive-grade reliability standards. Seated height is 0.024" (0.60mm) compared to 0.026" (0.66mm) for the primary part, remaining within typical PCB assembly tolerances.

Both parts satisfy identical electrical and mechanical requirements. Selection between them depends on application context: the Samsung part for standard applications, the Vishay part for automotive or high-reliability environments where AEC-Q200 qualification is specified or preferred.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M24FKEA directly replace RCS3216F1244CS on existing PCBs?

A: Yes. Both parts share identical resistance (1.24 MOhms), tolerance (±1%), power rating (0.25W), package (1206), and physical dimensions (0.126" L x 0.063" W). The 0.002" (0.06mm) difference in seated height falls within standard PCB assembly tolerances and does not affect footprint compatibility.

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

A: AEC-Q200 is an automotive industry qualification standard. The CRCW12061M24FKEA meets this certification, indicating it has undergone additional reliability testing for automotive applications. The RCS3216F1244CS does not carry this certification but meets standard industrial compliance requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RCS3216F1244CS and CRCW12061M24FKEA are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: What is MSL 1 and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. Both parts carry MSL 1 rating, eliminating moisture-related handling constraints.

Q: Can these parts be used interchangeably in all applications?

A: Electrical and mechanical interchangeability is confirmed. Application-specific requirements (such as automotive qualification mandates) determine whether the additional AEC-Q200 certification of the Vishay part is necessary. Consult application specifications for certification requirements.
