Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F5494CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

Resistance value: 5.49 MOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.125W / 1/8W (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C to 155°C (exact match or wider range acceptable)

Critical Mechanical Parameters:

Package designation: 0805 (2012 Metric) (exact match required)
Composition: Thick Film (exact match required)
Number of terminations: 2 (exact match required)

Compliance Parameters:

RoHS Status: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match or lower MSL acceptable)

The CRCW08055M49FKEA from Vishay Dale meets all critical parameters and qualifies as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can CRCW08055M49FKEA replace RC2012F5494CS in existing designs?

A: Yes. Both components share identical resistance value (5.49 MOhms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Electrical and mechanical compatibility is confirmed.

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

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive environmental and operational stress conditions. This rating does not restrict use in non-automotive applications; it indicates enhanced qualification testing and reliability assurance.

Q: Does the height difference (0.66mm vs 0.50mm) affect compatibility?

A: No. The Vishay Dale component has a lower seated height, which is mechanically compatible with PCB designs accommodating the Samsung component. Lower height provides additional clearance margin and does not create interference issues.

Q: Are both components RoHS3 compliant?

A: Yes. Both RC2012F5494CS and CRCW08055M49FKEA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life without moisture bake-out requirements. Both components carry this rating, eliminating moisture management concerns during storage and handling.

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

A: Yes. Both components operate across the identical temperature range of -55°C to 155°C with matching temperature coefficient specifications (±100ppm/°C), ensuring consistent performance across the full operating envelope.

Q: What packaging format is supplied?

A: Both components are supplied in Tape & Reel (TR) format, standard for automated PCB assembly processes.
