RCS2012F434CS Equivalent & Substitute Parts

Part Overview

The RCS2012F434CS is a 430 kOhms ±1% 0.125W thick film chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The RCS2012F434CS features anti-sulfur and moisture-resistant construction, operating across -55°C to 155°C temperature range with ±100ppm/°C temperature coefficient.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain disruptions, or specific application certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F434CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 430 kOhms
• 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
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)

All four substitute parts listed meet these mandatory parameters. Substitute parts are grouped into two categories based on additional certifications: automotive-qualified (AEC-Q200) and general industrial use.

Parameter Comparison

Engineering Selection Recommendations

For General Industrial Applications: The RCS2012F434CS (Samsung Electro-Mechanics) and RC0805FR-07430KL (YAGEO) are functionally equivalent for non-automotive applications. Both components share identical electrical specifications and environmental ratings. Selection between these two depends on packaging preference and inventory availability. The RCS2012F434CS is supplied in Tape & Reel format, while the RC0805FR-07430KL is available in Cut Tape and Digi-Reel formats.

For Automotive Applications (AEC-Q200 Required): When automotive qualification is mandated by design specifications, substitute with CRCW0805430KFKEA (Vishay Dale), ERJ-6ENF4303V (Panasonic Electronic Components), or RMCF0805FT430K (Stackpole Electronics Inc). All three parts carry AEC-Q200 certification and meet identical electrical and environmental parameters. Selection among these three is based on inventory availability and packaging format preference, as all are supplied in Tape & Reel format.

Mechanical Compatibility Consideration: All substitute parts maintain 0805 (2012 Metric) package dimensions with minor variations in seated height (0.020" to 0.028"). These height variations are within standard PCB assembly tolerances and do not affect electrical performance or mechanical fit on standard 0805 footprints.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805430KFKEA replace RCS2012F434CS in a non-automotive design?

A: Yes. CRCW0805430KFKEA meets all electrical and environmental specifications of RCS2012F434CS. The AEC-Q200 automotive certification is an additional qualification that does not restrict use in general industrial applications. Substitution is electrically and mechanically valid.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape supplies components on cut segments of carrier tape, typically for manual assembly or lower-volume production. RC0805FR-07430KL is available in both Cut Tape and Digi-Reel formats. Electrical performance is identical regardless of packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the RCS2012F434CS specification.

Q: Does the seated height variation among substitute parts affect PCB assembly?

A: No. Seated height variations range from 0.020" to 0.028" (0.50mm to 0.70mm), which fall within standard PCB assembly tolerances for 0805 components. All parts are mechanically compatible with standard 0805 footprints.

Q: Which substitute part has the lowest seated height?

A: CRCW0805430KFKEA (Vishay Dale) has the lowest maximum seated height at 0.020" (0.50mm).

Q: Can I use ERJ-6ENF4303V in place of RCS2012F434CS for temperature-critical applications?

A: Yes. ERJ-6ENF4303V operates across the identical temperature range (-55°C ~ 155°C) with the same ±100ppm/°C temperature coefficient as RCS2012F434CS. Substitution is valid for temperature-critical applications.

Q: What inventory levels are available for each substitute part?

A: CRCW0805430KFKEA: 23,914 pcs; ERJ-6ENF4303V: 52,757 pcs; RC0805FR-07430KL: 41,295 pcs; RMCF0805FT430K: 11,796 pcs. All parts are in stock as new original components.
