Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3744CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 3.74 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3

The substitute part CRCW12063M74FKEA from Vishay Dale meets all critical electrical and mechanical parameters. Both components share identical resistance, tolerance, power rating, package dimensions, and thermal specifications. Compliance certifications (ROHS3, REACH Unaffected, EAR99) are equivalent across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F3744CS and CRCW12063M74FKEA are Active status components with equivalent electrical and mechanical specifications. Selection between these parts is based on the following factors:

RCS3216F3744CS (Samsung Electro-Mechanics): Features anti-sulfur and moisture-resistant construction. Suitable for general industrial applications requiring thick film 1206 resistors with standard environmental protection.

CRCW12063M74FKEA (Vishay Dale): Carries AEC-Q200 automotive qualification. Appropriate for automotive and mission-critical applications where automotive-grade component certification is required.

Both components are ROHS3 compliant, REACH unaffected, and classified under EAR99. The seated height difference (0.66mm vs 0.60mm) is within typical PCB assembly tolerances for 1206 packages and does not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW12063M74FKEA replace RCS3216F3744CS in any application?

A: Yes, provided the application does not specifically exclude automotive-qualified components. The CRCW12063M74FKEA meets all electrical and mechanical parameters of the RCS3216F3744CS. The AEC-Q200 rating is an additional qualification that does not restrict use in non-automotive circuits.

Q: What is the significance of the height difference between these parts?

A: The RCS3216F3744CS has a maximum seated height of 0.66mm, while the CRCW12063M74FKEA is 0.60mm. Both fall within standard 1206 package specifications and are compatible with typical PCB assembly processes. Height differences of this magnitude do not affect electrical performance or standard reflow soldering.

Q: Are there packaging differences between these substitutes?

A: The RCS3216F3744CS packaging is listed as "-" (unspecified in provided data). The CRCW12063M74FKEA is supplied in Tape & Reel (TR) format. Packaging format does not affect component electrical or mechanical compatibility; it only affects procurement and handling logistics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity level is 1 (Unlimited) for both parts, indicating no special moisture handling requirements during storage or assembly.

Q: What determines if a part is a valid substitute for the RCS3216F3744CS?

A: Valid substitutes must match the following parameters: 3.74 MOhms resistance, ±1% tolerance, 0.25W power rating, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance. Additional certifications (such as AEC-Q200) do not disqualify a part from substitution.
