RCS3216F3011CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F3011CS is a 3.01 kOhms ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This component features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part maintains active product status with 947 units in current inventory stock.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical compatibility (1206 package, 2 terminations, identical footprint dimensions). Substitutes are selected from manufacturers offering identical or functionally equivalent thick film compositions with ROHS3 compliance and MSL Level 1 rating.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

Resistance value: 3.01 kOhms
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
Terminations: 2
RoHS compliance: ROHS3
MSL rating: Level 1

All substitute parts listed meet these mandatory criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer-specific features (anti-sulfur, moisture resistant, automotive AEC-Q200 certification), and minor dimensional tolerances do not affect functional substitutability in standard circuit applications.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

The following parts are suitable for direct substitution in new circuit designs:

RMCF1206FT3K01 (Stackpole Electronics Inc): Highest inventory availability (102,594 units). Automotive AEC-Q200 certified. Active product status ensures long-term supply continuity.
CRCW12063K01FKEA (Vishay Dale): Automotive AEC-Q200 certified with 35,512 units in stock. Cut Tape & Digi-Reel packaging option available.
CR1206-FX-3011ELF (Bourns Inc.): Largest inventory reserve (53,686 units). Moisture-resistant thick film composition. Tape & Reel packaging.
RMCS1206FT3K01 (Stackpole Electronics Inc): Anti-sulfur thick film composition matching the original RCS3216F3011CS feature set. Lower inventory (930 units) but functionally equivalent.
RC1206FR-073K01L (YAGEO): Moisture-resistant thick film composition. Active status with 5,387 units available.

Secondary Substitute (Legacy Status):

ERJ-8ENF3011V (Panasonic Electronic Components): Marked "Not For New Designs." Suitable only for replacement in existing production runs or field service applications. Automotive AEC-Q200 certified. 20,400 units in inventory.

Special Application Consideration:

CRCW12063K01FKEAHP (Vishay Dale): Higher power rating (0.75W vs. 0.25W) with pulse withstanding capability. Use only when circuit design requires enhanced power dissipation or transient protection. Not a direct substitute for standard 0.25W applications.

Frequently Asked Questions (FAQ)

Q: Can I use CRCW12063K01FKEAHP as a direct replacement for RCS3216F3011CS?

A: CRCW12063K01FKEAHP has a 0.75W power rating compared to the 0.25W specification of RCS3216F3011CS. While physically compatible in the 1206 package, this part is not a direct substitute. Use only if circuit design specifically requires higher power dissipation capability.

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

A: Both packaging formats contain identical components with identical electrical and mechanical specifications. Tape & Reel (TR) packaging is used for automated assembly lines. Cut Tape (CT) & Digi-Reel packaging is used for manual assembly or lower-volume applications. Selection depends on manufacturing process requirements, not component performance.

Q: Why is ERJ-8ENF3011V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. The part remains available for existing production support and field replacement. For new designs, select from parts with "Active" product status.

Q: Are all listed substitutes automotive-grade?

A: No. Only CRCW12063K01FKEA, CRCW12063K01FKEAHP, ERJ-8ENF3011V, and RMCF1206FT3K01 carry automotive AEC-Q200 certification. CR1206-FX-3011ELF, RC1206FR-073K01L, and RMCS1206FT3K01 are industrial-grade components. Select automotive-certified parts only for automotive applications requiring AEC-Q200 compliance.

Q: What does MSL Level 1 mean?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without moisture-barrier packaging. All listed parts have MSL Level 1 rating, meaning they can be stored and handled under standard conditions without special moisture-control requirements.

Q: Can I mix different manufacturers' parts in the same circuit board?

A: Yes. All listed substitutes meet identical electrical specifications (3.01 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical compatibility (1206 package, 2 terminations). Mixing manufacturers is acceptable from a functional standpoint. However, maintain consistent sourcing within production batches when possible to simplify supply chain management and traceability.

Q: What is the significance of anti-sulfur and moisture-resistant features?

A: Anti-sulfur composition (RCS3216F3011CS, RMCS1206FT3K01) provides enhanced resistance to sulfur-containing atmospheric contaminants. Moisture-resistant thick film (CR1206-FX-3011ELF, RC1206FR-073K01L) improves performance in high-humidity environments. Both features are optional enhancements; standard thick film substitutes (RMCF1206FT3K01, CRCW12063K01FKEA) are functionally equivalent in typical operating conditions.
