RCS2012F15R4CS Equivalent & Substitute Parts

Part Overview

The RCS2012F15R4CS is a 15.4 Ohms ±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 and is designed for general-purpose applications requiring precision resistive elements with anti-sulfur and moisture-resistant properties. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or specific feature requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F15R4CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 15.4 Ohms
• 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
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical dimensions (height-seated maximum) and additional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution but represent secondary feature differences.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the RCS2012F15R4CS based on matching core parameters: 15.4 Ohms resistance, ±1% tolerance, 0.125W power rating, 0805 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance.

RMCF0805FT15R4 (Stackpole Electronics Inc): Automotive AEC-Q200 qualified. Seated height (0.026") matching original specification. Limited inventory (969 pcs). Suitable for automotive applications with specific sourcing requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW080515R4FKEA replace RCS2012F15R4CS in non-automotive applications?

A: Yes. The CRCW080515R4FKEA meets all mandatory electrical and mechanical parameters. AEC-Q200 automotive qualification is an additional feature that does not restrict use in general-purpose applications.

Q: What is the significance of the height-seated maximum variation across substitute parts?

A: Height-seated maximum values range from 0.020" to 0.028". These variations are within typical PCB design tolerances for 0805 package components. Verify specific PCB clearance requirements for your application before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the original RCS2012F15R4CS specification.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF15R4V (Panasonic Electronic Components) has the highest inventory stock at 145,846 pcs, followed by CRCW080515R4FKEA (Vishay Dale) at 20,768 pcs.

Q: Do substitute parts with AEC-Q200 certification cost more?

A: Cost information is not provided in the technical specifications. Contact your supplier for pricing comparison between automotive-qualified and non-qualified alternatives.

Q: Can I mix substitute parts in the same production batch?

A: All substitute parts are electrically and mechanically equivalent. Mixing is permissible from a functional standpoint. Verify your quality assurance and traceability requirements before implementing mixed-source procurement.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur protection addresses corrosion from sulfur-containing environments. Moisture-resistant composition addresses humidity exposure. Both features are environmental protection mechanisms. The original RCS2012F15R4CS includes both; substitute parts include moisture-resistant or automotive-grade protection.
