RCS3216F20R5CS Equivalent & Substitute Parts

Part Overview

The RCS3216F20R5CS is a 20.5 Ohm ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component is classified as Active product status and features anti-sulfur and moisture-resistant construction. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and package compatibility align with the main part's core parameters. This reference provides engineering-grade alternatives for component selection and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F20R5CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

Resistance value: 20.5 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
Termination count: 2
RoHS compliance: ROHS3
MSL rating: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 1206 package tolerance and differences in feature sets (such as automotive AEC-Q200 certification or anti-sulfur coating) do not disqualify substitution when core parameters align.

Engineering Selection Recommendations

For Active Product Status Applications: The CRCW120620R5FKEA (Vishay Dale) and RC1206FR-0720R5L (YAGEO) are both classified as Active products and are suitable for new designs. Both parts maintain full electrical and mechanical compatibility with the RCS3216F20R5CS.

The CRCW120620R5FKEA includes automotive AEC-Q200 certification, which provides additional qualification for automotive applications. The RC1206FR-0720R5L features moisture-resistant construction similar to the main part.

For Legacy or Existing Designs: The ERJ-8ENF20R5V (Panasonic) is classified as "Not For New Designs" and should be used only in existing production or maintenance scenarios where component continuity is required. This part carries automotive AEC-Q200 certification and meets all electrical specifications.

Compliance Considerations: All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the main part. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can CRCW120620R5FKEA replace RCS3216F20R5CS in any application?

A: Yes. The CRCW120620R5FKEA meets all critical electrical parameters (20.5 Ohms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and is mechanically compatible in the 1206 package. The automotive AEC-Q200 certification is an additional qualification that does not prevent use in non-automotive applications.

Q: What is the difference between the main part and RC1206FR-0720R5L?

A: Both parts are electrically and mechanically equivalent. The RC1206FR-0720R5L has a slightly smaller length dimension (3.10mm vs 3.20mm) and lower seated height (0.65mm vs 0.66mm), both within 1206 package tolerance. Both feature moisture-resistant construction.

Q: Why is ERJ-8ENF20R5V marked "Not For New Designs"?

A: The ERJ-8ENF20R5V carries a "Not For New Designs" status from Panasonic, indicating the manufacturer recommends against using this part in new product development. However, it remains electrically and mechanically compatible and may be used for legacy system maintenance or existing production runs.

Q: Are there packaging differences between these parts?

A: The RCS3216F20R5CS is supplied in standard packaging. The CRCW120620R5FKEA, ERJ-8ENF20R5V, and RC1206FR-0720R5L are all supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount applications.

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

A: Yes. All parts, including the main part RCS3216F20R5CS, carry MSL 1 (Unlimited) rating, meaning there are no moisture sensitivity restrictions for storage, handling, or reflow processes.
