Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F1374CS and CRCW12061M37FKEA are Active production parts with equivalent electrical and mechanical specifications. Selection between these components should be based on:

Availability and Lead Time: The CRCW12061M37FKEA has higher inventory availability (15130 pieces) compared to the RCS3216F1374CS (1127 pieces), making it suitable for high-volume procurement scenarios.

Compliance Certifications: The CRCW12061M37FKEA carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Both parts maintain ROHS3 compliance and REACH unaffected status.

Packaging Format: The RCS3216F1374CS is supplied in standard packaging, while the CRCW12061M37FKEA is available in Cut Tape (CT) and Digi-Reel® formats, offering flexibility for different assembly processes.

Physical Dimensions: The CRCW12061M37FKEA has a slightly lower seated height (0.024" vs 0.026"), which may be advantageous in space-constrained PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M37FKEA be used as a direct replacement for RCS3216F1374CS?

A: Yes. Both components share identical electrical specifications (1.37 MOhms ±1%, 0.25W), identical package dimensions (1206/3216 Metric), and equivalent compliance certifications (ROHS3, REACH Unaffected, MSL 1). Physical height difference (0.024" vs 0.026") is within standard PCB assembly tolerances and does not affect electrical performance or mechanical fit.

Q: What are the key parameters that must match for substitution?

A: Resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package type, composition, and compliance certifications must all match exactly. The RCS3216F1374CS and CRCW12061M37FKEA meet all these criteria.

Q: Does the AEC-Q200 rating on the Vishay part affect compatibility?

A: No. AEC-Q200 is an additional qualification that exceeds the base requirements. A part with AEC-Q200 certification can be used in applications that do not require it without any negative impact.

Q: Are there packaging differences between these parts?

A: The RCS3216F1374CS uses standard packaging, while the CRCW12061M37FKEA is available in Cut Tape (CT) and Digi-Reel® formats. Both are suitable for automated assembly; packaging choice depends on production volume and assembly equipment compatibility.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. Both parts have this rating, meaning they can be stored and handled under standard conditions without special moisture control procedures.
