RCS3216F2800CS Equivalent & Substitute Parts

Part Overview

The RCS3216F2800CS is a 280 Ohms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is RoHS3 compliant and carries MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are necessary when the original RCS3216F2800CS becomes unavailable, when alternative sourcing reduces procurement costs, or when design requirements mandate specific certifications such as automotive AEC-Q200 qualification.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F2800CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

Resistance value: 280 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
RoHS3 compliance
MSL 1 rating

All four substitute parts listed below meet these exact specifications. Variations in physical dimensions (length, width, height) and packaging format (Tape & Reel vs. Cut Tape) do not affect electrical equivalence but may impact assembly and procurement workflows.

Engineering Selection Recommendations

For Active Product Status Applications: Select from AC1206FR-07280RL (YAGEO), CRCW1206280RFKEA (Vishay Dale), or RC1206FR-07280RL (YAGEO). All three maintain Active product status, ensuring long-term availability and manufacturer support.

For Automotive Applications: AC1206FR-07280RL and CRCW1206280RFKEA both carry AEC-Q200 automotive qualification. These parts are suitable for automotive-grade circuit designs requiring enhanced reliability standards.

For Non-Automotive Applications: RC1206FR-07280RL provides equivalent electrical performance without automotive certification overhead, suitable for industrial and consumer applications.

Avoid for New Designs: ERJ-8ENF2800V carries "Not For New Designs" status. While electrically equivalent and currently in stock, this part should not be selected for new product development due to manufacturer discontinuation trajectory.

Compliance Verification: All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating, matching the original RCS3216F2800CS compliance profile.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07280RL replace RCS3216F2800CS in non-automotive circuits?

A: Yes. AC1206FR-07280RL meets all electrical and mechanical specifications of RCS3216F2800CS. AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive applications.

Q: What is the difference between the YAGEO AC1206FR-07280RL and RC1206FR-07280RL models?

A: AC1206FR-07280RL includes AEC-Q200 automotive qualification and moisture resistance. RC1206FR-07280RL provides moisture resistance without automotive certification. Both are electrically identical with ±1% tolerance and 0.25W power rating in 1206 package.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist. RCS3216F2800CS and CRCW1206280RFKEA measure 0.126" L × 0.063" W, while AC1206FR-07280RL and RC1206FR-07280RL measure 0.122" L × 0.063" W. Height differences range from 0.024" to 0.028". These variations are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Why is ERJ-8ENF2800V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) is discontinuing this product line. While currently available in inventory, selecting this part for new designs creates long-term supply risk.

Q: Do all substitute parts support the same temperature range?

A: Yes. All substitute parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, matching RCS3216F2800CS specifications.

Q: What packaging formats are available?

A: RCS3216F2800CS uses standard packaging (not specified). AC1206FR-07280RL and RC1206FR-07280RL are supplied in Tape & Reel (TR) format. CRCW1206280RFKEA is also Tape & Reel. ERJ-8ENF2800V is available in Cut Tape (CT) & Digi-Reel format. Packaging format selection depends on assembly equipment and procurement volume requirements.

Q: Are all parts RoHS3 and REACH compliant?

A: Yes. All five parts (original and four substitutes) are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for EU and global markets.
