Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F2944CS are qualified based on the following criteria:

Electrical Parameters: Resistance value (2.94 MOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Parameters: Package type (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W), and number of terminations (2) must match.

Environmental & Compliance: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL rating (1) must be maintained.

Composition: Thick film construction is required for substitution eligibility.

The following parts meet all substitution criteria for the RCS2012F2944CS:

• CRCW08052M94FKEA (Vishay Dale)
• RC0805FR-072M94L (YAGEO)

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS2012F2944CS, CRCW08052M94FKEA, and RC0805FR-072M94L—are Active status components with ROHS3 compliance and identical electrical specifications. Selection between these parts is based on availability, supply chain requirements, and specific application certifications.

CRCW08052M94FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring this certification standard.

RC0805FR-072M94L and RCS2012F2944CS are qualified for general industrial and commercial applications with moisture-resistant properties.

Height variations (0.026" maximum for RCS2012F2944CS, 0.020" for CRCW08052M94FKEA, and 0.024" for RC0805FR-072M94L) are within acceptable tolerances for 0805 package specifications and do not affect functional substitution in standard PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052M94FKEA replace RCS2012F2944CS in non-automotive applications?

A: Yes. CRCW08052M94FKEA meets all electrical and mechanical substitution criteria. The AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits.

Q: Are there differences in moisture resistance between these parts?

A: All three parts carry MSL 1 (Unlimited) rating. RCS2012F2944CS and RC0805FR-072M94L are explicitly specified as moisture resistant. CRCW08052M94FKEA does not list this feature in the provided data but maintains the same MSL rating.

Q: Do the height differences affect PCB assembly?

A: Height variations (0.020" to 0.026") are within standard 0805 package tolerances and do not impact automated pick-and-place assembly or reflow soldering processes.

Q: Which part should be selected for high-reliability applications?

A: Selection depends on application requirements. CRCW08052M94FKEA is qualified to AEC-Q200 for automotive use. RCS2012F2944CS and RC0805FR-072M94L are suitable for industrial applications with equivalent environmental ratings.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. RCS2012F2944CS, CRCW08052M94FKEA, and RC0805FR-072M94L are all supplied in Tape & Reel (TR) packaging for automated assembly.
