Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F4424CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 4.42 MOhms, tolerance of ±1%, and power rating of 0.125W (1/8W) must match exactly.

Mechanical Parameters: Package designation 0805 (2012 Metric) with compatible physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) ensures PCB footprint compatibility.

Environmental Performance: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C must be maintained.

Compliance & Certifications: RoHS3 compliance and MSL 1 rating are required. Additional certifications such as AEC-Q200 for automotive applications represent enhanced qualification levels.

Composition: Thick film construction is the specified technology.

Substitutes are grouped by packaging format (Tape & Reel vs. Cut Tape) and manufacturer, with variations in feature sets (anti-sulfur coating, automotive qualification) noted where applicable.

Parameter Comparison

Engineering Selection Recommendations

RC2012F4424CS (Samsung Electro-Mechanics): This substitute maintains identical electrical and thermal specifications with the main part. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and the absence of anti-sulfur coating. Selection is appropriate for applications where bulk component handling is acceptable and sulfur exposure is not a concern. Product status is Active with ROHS3 compliance confirmed.

CRCW08054M42FKEA (Vishay Dale): This substitute meets all core electrical and mechanical requirements with AEC-Q200 automotive qualification. The seated height is 0.020" (0.50mm) compared to 0.026" (0.66mm) for the main part, which may affect PCB clearance in space-constrained designs. Selection is recommended for automotive applications requiring AEC-Q200 certification. Product status is Active with ROHS3 compliance confirmed.

All three parts are ROHS3 compliant with MSL 1 rating and maintain the required operating temperature range and temperature coefficient specifications.

Frequently Asked Questions (FAQ)

Q: Can RC2012F4424CS replace RCS2012F4424CS in all applications?

A: RC2012F4424CS is electrically and thermally equivalent. The main differences are packaging format (Cut Tape vs. Tape & Reel) and the absence of anti-sulfur coating in the RC variant. For applications requiring anti-sulfur protection or specific packaging requirements, verify compatibility before substitution.

Q: What is the significance of the AEC-Q200 rating on CRCW08054M42FKEA?

A: AEC-Q200 is an automotive qualification standard. CRCW08054M42FKEA meets this standard, making it suitable for automotive applications. Non-automotive applications do not require this certification.

Q: Are there physical compatibility concerns when substituting CRCW08054M42FKEA?

A: CRCW08054M42FKEA has a maximum seated height of 0.020" (0.50mm) versus 0.026" (0.66mm) for RCS2012F4424CS. This lower profile may affect PCB layout in designs with tight vertical clearance specifications. Verify PCB design constraints before substitution.

Q: Do all three parts have the same moisture sensitivity level?

A: Yes. All three parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.

Q: What packaging formats are available?

A: RCS2012F4424CS and CRCW08054M42FKEA are supplied in Tape & Reel (TR) format. RC2012F4424CS is supplied in Cut Tape (CT) format. Select based on assembly equipment and procurement requirements.

Q: Are all parts ROHS3 compliant?

A: Yes. RCS2012F4424CS, RC2012F4424CS, and CRCW08054M42FKEA are all ROHS3 compliant.
