RCS3216F274CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F274CS is a 270 kOhms ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This component is classified as Active product status with anti-sulfur and moisture-resistant construction. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F274CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

Resistance value: 270 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package format: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
RoHS compliance: ROHS3 Compliant
Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard 1206 package tolerances do not affect substitutability. Product status and additional certifications (such as AEC-Q200 automotive qualification) represent secondary differentiators for application-specific requirements but do not disqualify substitution based on core electrical parameters.

Engineering Selection Recommendations

Primary Selection (Active Status, Preferred for New Designs):

For new circuit designs and production applications, select from parts with Active product status: AC1206FR-07270KL (YAGEO), CR1206-FX-2703ELF (Bourns Inc.), CRCW1206270KFKEA (Vishay Dale), KTR18EZPF2703 (Rohm Semiconductor), or RC1206FR-07270KL (YAGEO). These components offer long-term availability and manufacturer support.

Automotive Applications:

When AEC-Q200 automotive qualification is required, select AC1206FR-07270KL, CRCW1206270KFKEA, ERJ-8ENF2703V, or KTR18EZPF2703. These parts carry explicit automotive certification.

High-Voltage Applications:

KTR18EZPF2703 includes high-voltage thick film construction as an additional feature beyond base specifications.

Legacy Design Maintenance:

ERJ-8ENF2703V carries "Not For New Designs" status but remains electrically equivalent for existing circuit maintenance and repair applications.

Inventory Availability:

KTR18EZPF2703 maintains the highest inventory level (199,386 pcs), followed by CR1206-FX-2703ELF (25,759 pcs) and CRCW1206270KFKEA (15,769 pcs), supporting high-volume procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F274CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts match the critical electrical parameters (270 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C operating range) and package format (1206). Direct substitution is electrically valid without circuit modification.

Q: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates automotive-grade qualification with enhanced reliability testing and traceability. Parts without this certification (RCS3216F274CS, CR1206-FX-2703ELF, RC1206FR-07270KL) are suitable for general industrial and consumer applications. Selection depends on application requirements, not electrical equivalence.

Q: Why is ERJ-8ENF2703V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for this part number. It remains electrically equivalent and available for existing design maintenance but should not be selected for new product development. Prefer Active-status alternatives for long-term supply assurance.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within 1206 package tolerances. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), width is consistent at 0.063" (1.60mm), and height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). These variations fall within standard PCB footprint design margins and do not affect substitutability.

Q: Which substitute part offers the best inventory availability?

A: KTR18EZPF2703 (Rohm Semiconductor) provides the highest stock level at 199,386 pieces, suitable for high-volume production requirements.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts, including the original RCS3216F274CS, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
