Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1914CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 1.91 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 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The CRCW12061M91FKEA from Vishay Dale meets all electrical and mechanical specifications. Both parts share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both maintain ROHS3 compliance and MSL 1 rating. The substitute part includes automotive AEC-Q200 qualification, which represents an additional certification layer beyond the base requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F1914CS and CRCW12061M91FKEA are Active products with full ROHS3 compliance and MSL 1 rating. Selection between these parts is based on application-specific requirements and supply chain considerations.

The RCS3216F1914CS features anti-sulfur and moisture-resistant properties specific to Samsung's thick film technology. The CRCW12061M91FKEA includes automotive AEC-Q200 qualification, indicating suitability for automotive applications with enhanced reliability requirements. Both parts maintain identical electrical performance across the specified operating temperature range of -55°C to 155°C.

Physical dimensions are equivalent within tolerance, with the Vishay Dale part showing a maximum seated height of 0.024" (0.60mm) compared to 0.026" (0.66mm) for the Samsung part. This minor difference does not affect PCB layout compatibility for standard 1206 package footprints.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M91FKEA directly replace RCS3216F1914CS in existing designs?

A: Yes. Both parts share identical electrical specifications (1.91 MOhms ±1%, 0.25W), package dimensions (1206/3216 Metric), and operating temperature range (-55°C ~ 155°C). PCB footprints and circuit performance remain unchanged.

Q: What is the difference between anti-sulfur/moisture-resistant and AEC-Q200 qualifications?

A: Anti-sulfur and moisture-resistant properties are material-level protections in the Samsung part. AEC-Q200 is an automotive qualification standard applied to the Vishay Dale part, indicating compliance with automotive reliability and testing requirements. These represent different qualification approaches rather than conflicting specifications.

Q: Are there packaging differences between these parts?

A: The RCS3216F1914CS packaging is listed as "-" (not specified in provided data). The CRCW12061M91FKEA is supplied in Tape & Reel (TR) format. Both use identical 1206 package geometry. Verify packaging requirements for your procurement process.

Q: Do both parts meet RoHS and REACH compliance?

A: Yes. Both RCS3216F1914CS and CRCW12061M91FKEA are ROHS3 Compliant and REACH Unaffected, with identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. Both parts can be stored and handled without time-dependent moisture sensitivity constraints, simplifying inventory management and assembly processes.
