Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F3744CS is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Resistance value: 3.74 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Requirements:

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

The substitute part CRCW08053M74FKEA meets all critical electrical and mechanical parameters. Both components share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Both are packaged in 0805 (2012 Metric) format with matching physical dimensions and termination count. Both achieve ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS2012F3744CS and CRCW08053M74FKEA are Active product status components with full ROHS3 compliance and MSL 1 rating. The electrical specifications are identical across resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Mechanical compatibility is confirmed through matching 0805 (2012 Metric) package dimensions and termination configuration.

The CRCW08053M74FKEA carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The seated height difference (0.026" versus 0.020" maximum) is within typical PCB assembly tolerances and does not affect functional compatibility in standard applications.

Selection between these components should be based on application requirements, supply chain availability, and any specific automotive or reliability certifications mandated by the end application.

Frequently Asked Questions (FAQ)

Q: Can CRCW08053M74FKEA be used as a direct replacement for RCS2012F3744CS?

A: Yes. Both components share identical electrical specifications (3.74 MOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), identical package format (0805 / 2012 Metric), and matching physical dimensions (0.079" L x 0.049" W). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the significance of the AEC-Q200 rating on the CRCW08053M74FKEA?

A: AEC-Q200 is an automotive qualification standard. The CRCW08053M74FKEA meets this automotive-grade reliability specification, while the RCS2012F3744CS does not carry this designation. For non-automotive applications, this difference is not relevant to component selection.

Q: Are there dimensional compatibility concerns between these parts?

A: Both components conform to the 0805 (2012 Metric) package standard with identical length and width (0.079" x 0.049"). The maximum seated height differs slightly (0.026" versus 0.020"), but this variation is within standard PCB assembly tolerances and does not affect placement or functionality.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RCS2012F3744CS and CRCW08053M74FKEA are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Both carry EAR99 ECCN classification and the same HTSUS code (8533.21.0030).

Q: What determines substitution eligibility for 0805 chip resistors?

A: Substitution is determined by matching resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package type, physical dimensions, and compliance certifications. All these parameters must align between the original and substitute component.
