Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4224CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 4.22 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
• REACH unaffected status

The CRCW08054M22FKEA from Vishay Dale meets all critical electrical and mechanical parameters. This substitute maintains identical resistance, tolerance, power rating, temperature coefficient, and operating range. Both components use 0805 packaging with matching termination count and dimensional specifications. Both achieve ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both the RC2012F4224CS and CRCW08054M22FKEA are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

The RC2012F4224CS features moisture-resistant thick film construction and is suitable for general industrial applications requiring standard reliability.

The CRCW08054M22FKEA carries AEC-Q200 automotive qualification, making it appropriate for automotive and high-reliability applications where automotive-grade component certification is specified. This part has a maximum seated height of 0.020" (0.50mm) compared to 0.026" (0.65mm) for the Samsung part, providing a marginal height advantage in space-constrained designs.

Both components share identical electrical performance, dimensional footprint compatibility, and regulatory compliance status. The choice between them is determined by whether automotive-grade qualification is required for the application.

Frequently Asked Questions (FAQ)

Q: Can CRCW08054M22FKEA directly replace RC2012F4224CS in existing designs?

A: Yes. Both components have identical resistance (4.22 MOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and 0805 package dimensions (2.00mm x 1.25mm). PCB footprints are interchangeable.

Q: What is the primary difference between these two parts?

A: The CRCW08054M22FKEA includes AEC-Q200 automotive qualification, while the RC2012F4224CS is specified for general industrial use. The Vishay part has a lower maximum seated height (0.020" vs 0.026").

Q: Are both parts RoHS compliant?

A: Yes. Both RC2012F4224CS and CRCW08054M22FKEA are ROHS3 compliant and REACH unaffected.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled without special desiccant packaging or moisture-barrier precautions.

Q: Which part should I select for automotive applications?

A: The CRCW08054M22FKEA is qualified to AEC-Q200 automotive standards and is the appropriate choice for automotive applications. The RC2012F4224CS is suitable for non-automotive industrial applications.

Q: Do these parts have identical physical dimensions?

A: Both use 0805 (2012 Metric) packaging with 2.00mm length and 1.25mm width. The CRCW08054M22FKEA has a maximum seated height of 0.020" (0.50mm) versus 0.026" (0.65mm) for the RC2012F4224CS, a difference of 0.006" that may be relevant in height-constrained assemblies.
