Substitute Part Grouping Explanation

Substitute parts for the RCS2012F6494CS are qualified based on strict electrical and mechanical parameter alignment:

Qualifying Criteria:

• Resistance value: 6.49 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), seated height tolerances, and additional certifications (such as AEC-Q200) do not disqualify substitution when core electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three components—RCS2012F6494CS, CRCW08056M49FKEA, and RC0805FR-076M49L—are Active product status and fully compliant with ROHS3 and REACH regulations. Selection between these parts is determined by application-specific requirements and supply chain considerations:

RCS2012F6494CS (Samsung Electro-Mechanics): Features anti-sulfur and moisture resistant characteristics with seated height of 0.66mm maximum.

CRCW08056M49FKEA (Vishay Dale): Includes AEC-Q200 automotive qualification with the lowest seated height of 0.50mm maximum, suitable for applications requiring automotive-grade reliability.

RC0805FR-076M49L (YAGEO): Offers moisture resistant characteristics with seated height of 0.60mm maximum and highest inventory availability among the three options.

All parts share identical electrical specifications and mechanical footprint compatibility, enabling direct substitution based on packaging availability, delivery requirements, and application-specific certifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW08056M49FKEA replace RCS2012F6494CS in any application?

A: Yes. Both components share identical resistance (6.49 MOhms), tolerance (±1%), power rating (0.125W), package (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The seated height difference (0.50mm vs. 0.66mm) is within typical PCB design tolerances for 0805 components.

Q: What is the difference between the three substitute parts?

A: The three parts are electrically and mechanically equivalent. Differences include: RCS2012F6494CS features anti-sulfur protection; CRCW08056M49FKEA includes AEC-Q200 automotive certification; RC0805FR-076M49L offers the highest inventory stock. All are ROHS3 compliant with MSL rating 1.

Q: Are seated height variations significant for PCB assembly?

A: Seated height variations (0.50mm to 0.66mm) are within standard 0805 component tolerances and do not affect PCB assembly compatibility or reflow soldering processes for typical surface mount applications.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All three components carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

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

A: RCS2012F6494CS, CRCW08056M49FKEA, and RC0805FR-076M49L are all Active status components with ROHS3 compliance. CRCW08056M49FKEA additionally carries AEC-Q200 automotive qualification. Selection depends on specific application reliability requirements and certification mandates.
