Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F5114CS is determined by strict equivalence across the following parameters:

• Electrical Specifications: Resistance value (5.11 MOhms), tolerance (±1%), and power rating (0.125W) must be identical
• Package Compatibility: 0805 (2012 Metric) package with matching footprint dimensions (0.079" L x 0.049" W)
• Environmental Performance: Temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and MSL rating (1) must be equivalent
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required
• Composition: Thick film construction

The identified substitute parts meet all these criteria and are qualified for direct replacement in applications where the RCS2012F5114CS is specified.

Frequently Asked Questions (FAQ)

Q: Can CRCW08055M11FKEA replace RCS2012F5114CS in standard applications?

A: Yes. Both parts share identical resistance (5.11 MOhms), tolerance (±1%), power rating (0.125W), package (0805), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The CRCW08055M11FKEA includes AEC-Q200 automotive qualification, which does not restrict use in non-automotive applications.

Q: What is the difference in physical dimensions between these parts?

A: All three parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height variations are minimal: RCS2012F5114CS (0.026"), RC0805FR-075M11L (0.024"), and CRCW08055M11FKEA (0.020"). These differences do not affect PCB layout compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RCS2012F5114CS, CRCW08055M11FKEA, and RC0805FR-075M11L are all ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All three parts operate across -55°C to 155°C with identical temperature coefficients (±100ppm/°C), ensuring equivalent performance in temperature-sensitive circuits.

Q: What is the MSL rating for these resistors?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
