Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1784CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 1.78 MOhms
• Tolerance: ±1%
• Power Rating: 0.25W (1/4W)
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The CRCW12061M78FKEA from Vishay Dale meets all mandatory parameters and qualifies as a direct substitute. Both components share identical electrical specifications, package dimensions, and environmental ratings. Differences in packaging format (Tape & Reel for substitute) and specific feature sets (Automotive AEC-Q200 certification for substitute) do not affect functional interchangeability in applications requiring this resistance value and performance profile.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F1784CS and CRCW12061M78FKEA are Active products with ROHS3 compliance and MSL 1 rating, confirming current manufacturing availability and environmental regulatory alignment. The RCS3216F1784CS features anti-sulfur and moisture-resistant construction. The CRCW12061M78FKEA carries Automotive AEC-Q200 certification, indicating qualification for automotive applications with enhanced reliability requirements.

Selection between these components should be based on application-specific requirements: the Samsung part for general industrial and consumer applications requiring anti-sulfur protection, and the Vishay Dale part for automotive or mission-critical applications where AEC-Q200 qualification is specified or preferred. Both components are electrically and mechanically interchangeable for the specified 1.78 MOhms ±1% 0.25W 1206 package requirement.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M78FKEA replace RCS3216F1784CS in existing designs?

A: Yes. Both components share identical resistance value (1.78 MOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Physical dimensions are equivalent, with the Vishay part having a slightly lower maximum seated height (0.024" vs 0.026"). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the anti-sulfur feature of RCS3216F1784CS and the AEC-Q200 certification of CRCW12061M78FKEA?

A: Anti-sulfur and moisture-resistant construction on the Samsung part addresses environmental protection in industrial settings. AEC-Q200 certification on the Vishay part indicates automotive-grade reliability qualification. These are distinct feature sets; neither is superior in all applications. Selection depends on end-use environment and application standards.

Q: Are there packaging differences between these parts?

A: The RCS3216F1784CS is supplied in standard packaging, while CRCW12061M78FKEA is supplied in Tape & Reel (TR) format. Both use the same 1206 (3216 Metric) package footprint and are compatible with standard PCB assembly processes. Tape & Reel packaging is standard for high-volume automated assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry HTSUS code 8533.21.0030. Moisture Sensitivity Level is 1 (Unlimited) for both parts.

Q: What is the temperature coefficient significance for these resistors?

A: Both parts have a temperature coefficient of ±100ppm/°C, meaning resistance value changes by approximately 100 parts per million for each degree Celsius change in operating temperature. This specification is identical for both components and determines their suitability for precision analog circuits within the -55°C to 155°C operating range.
