RCS2012F90R9CS Equivalent & Substitute Parts

Part Overview

The RCS2012F90R9CS is a 90.9 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part features anti-sulfur and moisture-resistant properties, with a temperature coefficient of ±100ppm/°C. Currently in active production status with 1006 units in stock, this resistor is ROHS3 compliant and MSL 1 rated. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and environmental compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F90R9CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 90.9 Ohms, tolerance of ±1%, power rating of 0.125W (1/8W), and temperature coefficient of ±100ppm/°C must match exactly.

Mechanical Parameters: Package format must be 0805 (2012 Metric) with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Number of terminations must be 2.

Environmental & Compliance: Operating temperature range of -55°C to 155°C, ROHS3 compliance, and MSL 1 rating are required for all substitutes.

Composition: Thick film construction is the standard for this category.

All identified substitute parts meet these criteria. Variations in packaging format (Tape & Reel versus Cut Tape), seated height, and additional certifications (such as AEC-Q200 automotive qualification) do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All four resistor models are electrically and mechanically equivalent for direct substitution in applications requiring a 90.9 Ohm ±1% 0805 thick film chip resistor. Selection among these parts should be based on the following factors:

Compliance Requirements: All parts are ROHS3 compliant and REACH unaffected. The CRCW080590R9FKEA and ERJ-6ENF90R9V carry AEC-Q200 automotive qualification, making them suitable for automotive applications where this certification is mandated.

Packaging Format: The RCS2012F90R9CS, ERJ-6ENF90R9V, and RC0805FR-0790R9L are supplied in Tape & Reel format. The CRCW080590R9FKEA is available in Cut Tape and Digi-Reel format. Selection depends on assembly line requirements and reel compatibility.

Inventory Availability: RC0805FR-0790R9L (YAGEO) offers the highest stock level at 116,482 units. ERJ-6ENF90R9V (Panasonic) provides 38,453 units, and CRCW080590R9FKEA (Vishay Dale) provides 20,309 units.

Physical Dimensions: Seated height varies slightly among parts (0.020" to 0.028"), which may be relevant for applications with strict height constraints. The CRCW080590R9FKEA has the lowest seated height at 0.020" (0.50mm).

Frequently Asked Questions (FAQ)

Q: Can the CRCW080590R9FKEA replace the RCS2012F90R9CS in a non-automotive application?

A: Yes. Both parts share identical electrical specifications (90.9 Ohms ±1%, 0.125W, ±100ppm/°C) and mechanical dimensions (0805 package, 2.00mm x 1.25mm). The AEC-Q200 automotive qualification on the Vishay part does not restrict its use in non-automotive circuits. The primary difference is packaging format (Cut Tape vs. Tape & Reel).

Q: Are there any height restrictions when substituting these resistors?

A: Seated height varies between 0.020" (0.50mm) for the CRCW080590R9FKEA and 0.028" (0.70mm) for the ERJ-6ENF90R9V. If your PCB layout has strict height clearance requirements, verify the seated height specification against your design constraints before selection.

Q: Do all substitute parts meet the same environmental standards?

A: Yes. All four parts are ROHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited moisture sensitivity level). All operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous reels suitable for automated pick-and-place assembly. Cut Tape and Digi-Reel formats provide smaller quantities on tape strips. Selection depends on production volume and assembly equipment compatibility.

Q: Can I use the ERJ-6ENF90R9V or CRCW080590R9FKEA in applications where AEC-Q200 is not required?

A: Yes. AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive applications. These parts are fully compatible with the RCS2012F90R9CS in any circuit requiring a 90.9 Ohm ±1% 0805 thick film resistor.

Q: Are the electrical performance characteristics identical across all four parts?

A: Yes. All parts share identical resistance value (90.9 Ohms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Electrical performance is equivalent.
