Substitute Part Grouping Explanation

Substitute parts for the RCS2012F2261CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

Resistance value: 2.26 kOhms
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)

Engineering Selection Recommendations

All four components listed are Active product status with full ROHS3 compliance and MSL Level 1 rating. Selection among these parts is determined by application-specific requirements:

CRCW08052K26FKEA (Vishay Dale): Includes AEC-Q200 automotive qualification. Lowest maximum seated height (0.020") provides optimal clearance for high-density PCB layouts. Suitable for automotive and industrial applications requiring automotive-grade reliability.

ERJ-6ENF2261V (Panasonic Electronic Components): Includes AEC-Q200 automotive qualification. Highest inventory availability (155,259 pcs). Maximum seated height of 0.028" accommodates standard PCB assembly processes. Suitable for high-volume production requiring extended lead time security.

RC0805FR-072K26L (YAGEO): Moisture-resistant thick film composition. Moderate maximum seated height (0.024"). Suitable for general-purpose applications where automotive qualification is not required.

RCS2012F2261CS (Samsung Electro-Mechanics): Anti-sulfur and moisture-resistant features. Original specification baseline for direct replacement applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052K26FKEA replace RCS2012F2261CS in non-automotive applications?

A: Yes. Both components share identical electrical specifications (2.26 kOhms ±1%, 0.125W), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL Level 1). The AEC-Q200 automotive qualification of CRCW08052K26FKEA does not restrict its use in non-automotive circuits.

Q: What is the significance of the height difference between substitute parts?

A: Maximum seated heights range from 0.020" to 0.028". These variations fall within standard PCB assembly tolerances for 0805 components and do not affect electrical performance or mechanical fit in standard 0805 footprints.

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

A: Yes. All components, including the original RCS2012F2261CS, operate across the identical temperature range of -55°C ~ 155°C with ±100ppm/°C temperature coefficient.

Q: What does MSL Level 1 (Unlimited) mean for these components?

A: MSL Level 1 indicates unlimited shelf life without moisture baking requirements. All listed components can be stored and handled without time-dependent moisture sensitivity constraints.

Q: Can ERJ-6ENF2261V be used in applications where anti-sulfur protection is critical?

A: The provided specifications do not list anti-sulfur features for ERJ-6ENF2261V. If anti-sulfur protection is a design requirement, RCS2012F2261CS or RC0805FR-072K26L should be selected based on their documented moisture-resistant characteristics.

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

A: Yes. All components listed are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
