RCS2012F3092CS Equivalent & Substitute Parts

Part Overview

The RCS2012F3092CS is a 30.9 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.125W (1/8W) in 0805 (2012 Metric) package format. This component features anti-sulfur and moisture-resistant construction with unlimited moisture sensitivity level (MSL 1). The part maintains Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across alternative manufacturers while preserving the same resistance value, tolerance, power rating, package dimensions, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F3092CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (30.9 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Compatibility: Package type (0805 / 2012 Metric), number of terminations (2), and physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) must match.

Regulatory Compliance: RoHS3 compliance and MSL 1 rating are maintained across all qualified substitutes.

All four identified substitute parts meet these criteria. Packaging format variations (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility and represent logistical alternatives only.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F3092CS based on electrical and mechanical parameters. Selection among these alternatives should be based on the following factors:

Compliance Certifications: CRCW080530K9FKEA (Vishay Dale), ERJ-6ENF3092V (Panasonic), and RMCF0805FT30K9 (Stackpole) carry AEC-Q200 automotive qualification ratings. RC0805FR-0730K9L (YAGEO) does not specify AEC-Q200 certification. Applications requiring automotive-grade components should prioritize the three AEC-Q200 qualified options.

Product Status: All parts maintain Active product status, ensuring continued availability and manufacturing support.

Packaging Format: RCS2012F3092CS, ERJ-6ENF3092V, RC0805FR-0730K9L, and RMCF0805FT30K9 are supplied in Tape & Reel format. CRCW080530K9FKEA is supplied in Cut Tape & Digi-Reel format. Packaging selection depends on assembly equipment compatibility and procurement requirements.

Inventory Availability: ERJ-6ENF3092V (Panasonic) offers the highest inventory level at 111,110 pieces. CRCW080530K9FKEA (Vishay Dale) provides 21,152 pieces. RC0805FR-0730K9L (YAGEO) and RMCF0805FT30K9 (Stackpole) offer 31,464 and 13,024 pieces respectively.

Frequently Asked Questions (FAQ)

Q: Can CRCW080530K9FKEA replace RCS2012F3092CS in automotive applications?

A: Yes. CRCW080530K9FKEA meets all electrical and mechanical specifications of RCS2012F3092CS and carries AEC-Q200 automotive qualification. The Cut Tape & Digi-Reel packaging format is the only difference from the original Tape & Reel format.

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

A: Height variations (0.020" to 0.028" seated maximum) fall within acceptable tolerances for 0805 package components and do not affect circuit board assembly or electrical performance. All parts maintain the same 0.079" L x 0.049" W footprint dimensions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four substitute parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original RCS2012F3092CS specification.

Q: Which substitute part should be selected for high-reliability applications?

A: ERJ-6ENF3092V (Panasonic), CRCW080530K9FKEA (Vishay Dale), and RMCF0805FT30K9 (Stackpole) all carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. These three options are preferred for high-reliability applications.

Q: Is the temperature coefficient identical across all parts?

A: Yes. All parts, including the original RCS2012F3092CS and all four substitutes, specify ±100ppm/°C temperature coefficient and -55°C ~ 155°C operating temperature range.

Q: Can packaging format be mixed within a single assembly?

A: Packaging format (Tape & Reel versus Cut Tape) affects procurement and assembly logistics but does not impact electrical or mechanical compatibility. Mixed packaging within a single assembly is permissible from an engineering standpoint, subject to assembly equipment capabilities and procurement procedures.
