RCS3216F2740CS Equivalent & Substitute Parts
Part Overview
The RCS3216F2740CS is a 274 Ohm ±1% 0.25W (1/4W) chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across a temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).
Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when specific application requirements necessitate alternative component specifications within the same functional parameters.

Substitute Part Grouping Explanation
Substitution eligibility for the RCS3216F2740CS is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Resistance value: 274 Ohms
- Tolerance: ±1%
- Power rating: 0.25W (1/4W)
- Package: 1206 (3216 Metric)
- Composition: Thick Film
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C ~ 155°C
- RoHS compliance: ROHS3
- Moisture sensitivity level: 1 (Unlimited)
- Termination count: 2
All substitute parts listed meet these mandatory parameters. Variations in physical dimensions (length, width, height) and packaging format (Tape & Reel versus bulk) do not affect functional substitutability. Feature differences such as anti-sulfur coating or automotive AEC-Q200 qualification represent enhancements that do not preclude substitution but may offer additional benefits for specific applications.

Engineering Selection Recommendations
Primary Substitutes (Active Product Status):
The CR1206-FX-2740ELF (Bourns Inc.), CRCW1206274RFKEA (Vishay Dale), and RC1206FR-07274RL (YAGEO) are all suitable direct substitutes with active product status. These parts maintain full electrical and mechanical compatibility with the RCS3216F2740CS across all critical parameters. The CRCW1206274RFKEA offers automotive AEC-Q200 qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The CR1206-FX-2740ELF and RC1206FR-07274RL provide moisture-resistant thick film construction equivalent to the primary part.
Secondary Substitute (Not For New Designs):
The ERJ-8ENF2740V (Panasonic Electronic Components) meets all functional and electrical requirements but carries a "Not For New Designs" product status. This part is electrically and mechanically equivalent and remains suitable for replacement in existing designs or legacy applications. However, for new design implementations, selection of an active-status substitute is preferred to ensure long-term availability and manufacturer support.
Compliance Considerations:
All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification identical to the primary part. Moisture sensitivity level remains at MSL 1 (Unlimited) across all options, indicating no special handling requirements during storage or assembly.
Frequently Asked Questions (FAQ)
Q: Can the CR1206-FX-2740ELF replace the RCS3216F2740CS in existing designs?
A: Yes. The CR1206-FX-2740ELF is a direct functional equivalent with identical resistance (274 Ohms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Both parts are ROHS3 compliant with MSL 1 rating.
Q: What is the difference between the CRCW1206274RFKEA and other substitutes?
A: The CRCW1206274RFKEA includes automotive AEC-Q200 qualification, which certifies the component for automotive applications with enhanced reliability testing. All other electrical and mechanical parameters remain identical to other substitutes. This qualification does not affect substitutability in non-automotive applications.
Q: Why is the ERJ-8ENF2740V marked "Not For New Designs"?
A: The "Not For New Designs" status indicates that Panasonic has discontinued active development and promotion of this part number. While the ERJ-8ENF2740V remains electrically and mechanically equivalent and suitable for replacement in existing designs, new design implementations should utilize active-status alternatives such as the CR1206-FX-2740ELF, CRCW1206274RFKEA, or RC1206FR-07274RL.
Q: Are there physical dimension differences between substitutes?
A: Minor variations exist in maximum seated height: RCS3216F2740CS (0.66mm), CR1206-FX-2740ELF (0.75mm), CRCW1206274RFKEA (0.60mm), ERJ-8ENF2740V (0.70mm), and RC1206FR-07274RL (0.65mm). These variations fall within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility. Length and width dimensions remain consistent at 3.20mm x 1.60mm across all parts.
Q: Do all substitutes support the same operating temperature range?
A: Yes. All substitute parts operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C, matching the RCS3216F2740CS specification.
Q: What packaging formats are available for substitutes?
A: The RCS3216F2740CS is supplied in standard packaging format. All listed substitutes are available in Tape & Reel (TR) format, which is the standard for high-volume SMD component distribution. Packaging format does not affect electrical or mechanical compatibility.
Q: Are all substitutes RoHS compliant?
A: Yes. All substitute parts maintain ROHS3 compliance identical to the primary part, with REACH unaffected status and EAR99 export classification.
