Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F245CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 2.4 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these mandatory criteria. Variations in maximum seated height and specific feature sets (anti-sulfur vs. automotive qualification) do not affect functional interchangeability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS2012F245CS, CRCW08052M40FKEA, and RC0805FR-072M4L—are functionally equivalent for applications requiring a 2.4 MOhms ±1% 0.125W 0805 chip resistor. Selection among these parts should be based on:

Product Availability: Inventory levels vary across manufacturers. CRCW08052M40FKEA (Vishay Dale) has the highest stock availability at 12,977 pieces, followed by RC0805FR-072M4L (YAGEO) at 4,815 pieces, and RCS2012F245CS (Samsung Electro-Mechanics) at 695 pieces.

Compliance Certifications: CRCW08052M40FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive applications. RCS2012F245CS and RC0805FR-072M4L do not specify automotive qualification but meet general industrial compliance requirements.

Physical Constraints: All parts fit within 0805 package dimensions. Maximum seated heights differ slightly (0.026" for Samsung, 0.020" for Vishay, 0.024" for YAGEO), which may be relevant for applications with strict height limitations.

Feature Set: RCS2012F245CS includes anti-sulfur properties in addition to moisture resistance. RC0805FR-072M4L specifies moisture resistance. CRCW08052M40FKEA emphasizes automotive qualification. These feature differences do not affect electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052M40FKEA replace RCS2012F245CS in any application?

A: Yes. Both parts meet identical electrical specifications (2.4 MOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), mechanical dimensions (0805 package, 2.00mm x 1.25mm), and compliance standards (ROHS3, MSL 1). The CRCW08052M40FKEA has a lower maximum seated height (0.020" vs. 0.026"), which is advantageous for space-constrained designs.

Q: What is the difference between the anti-sulfur feature on RCS2012F245CS and the automotive qualification on CRCW08052M40FKEA?

A: Anti-sulfur protection on the RCS2012F245CS addresses corrosion from sulfur-containing environments. AEC-Q200 qualification on the CRCW08052M40FKEA indicates compliance with automotive reliability standards. These are distinct feature sets addressing different application requirements. Neither feature affects the core electrical performance of the resistor.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All three parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C. Temperature performance is equivalent across all substitutes.

Q: Does the difference in seated height affect PCB design?

A: Seated height differences (0.020" to 0.026") are minor and typically do not affect standard PCB designs. However, in applications with strict height constraints or automated assembly specifications, the lower profile of CRCW08052M40FKEA (0.020") may be preferred.

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

A: Yes. RCS2012F245CS, CRCW08052M40FKEA, and RC0805FR-072M4L are all supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Which part should be selected for automotive applications?

A: CRCW08052M40FKEA carries AEC-Q200 automotive qualification and is the specified choice for automotive applications. RCS2012F245CS and RC0805FR-072M4L do not carry automotive certifications.
