Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1054CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 1.05 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
• Moisture sensitivity level: 1

The CRCW12061M05FKEA from Vishay Dale meets all electrical and mechanical specifications. Both parts share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both are ROHS3 compliant with 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 RCS3216F1054CS and CRCW12061M05FKEA are Active status components meeting ROHS3 compliance and MSL 1 requirements. The primary distinction is that CRCW12061M05FKEA carries AEC-Q200 automotive qualification, indicating additional reliability testing and qualification for automotive applications. Selection between these parts depends on application requirements: the Samsung part is suitable for general industrial and consumer applications, while the Vishay Dale part is qualified for automotive environments where AEC-Q200 certification is specified or required. Both parts are mechanically and electrically interchangeable within the stated parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M05FKEA directly replace RCS3216F1054CS?

A: Yes. Both parts share identical electrical specifications (1.05 MOhms ±1%, 0.25W), package dimensions (1206/3216 Metric), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Physical height differs by 0.002" (0.06mm), which is negligible for standard PCB assembly. Both are ROHS3 compliant with MSL 1.

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

A: AEC-Q200 is an automotive industry qualification standard. The CRCW12061M05FKEA has undergone additional reliability testing for automotive applications. This certification is not present on the Samsung part but does not affect electrical or mechanical compatibility in non-automotive applications.

Q: Are the package dimensions identical?

A: Yes. Both parts use 1206 (3216 Metric) package with dimensions 0.126" L x 0.063" W (3.20mm x 1.60mm). Maximum seated height differs slightly: Samsung 0.026" (0.66mm) versus Vishay 0.024" (0.60mm). This 0.002" difference is within standard PCB assembly tolerances.

Q: Do both parts meet RoHS requirements?

A: Yes. Both RCS3216F1054CS and CRCW12061M05FKEA are ROHS3 compliant and REACH unaffected.

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

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. Both parts carry MSL 1, meaning standard storage conditions are acceptable without desiccant packaging or special handling.
