RCS3216F225CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F225CS is a 2.2 MOhms ±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 the temperature range of -55°C to 155°C. The part is currently in active production status with 1019 units in stock.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, temperature coefficient) and mechanical compatibility (package type, dimensions, termination count). Substitute parts may offer alternative feature sets such as automotive AEC-Q200 certification or high-voltage capability while maintaining core electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F225CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

Resistance: 2.2 MOhms
Tolerance: ±1%
Power Rating: 0.25W (1/4W)
Temperature Coefficient: ±100ppm/°C
Operating Temperature Range: -55°C ~ 155°C

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS3216F225CS with any of the listed parts?

A: Yes, all listed parts except ERJ-8ENF2204V are suitable for direct substitution. All substitute parts match the core electrical specifications (2.2 MOhms, ±1% tolerance, 0.25W power rating, ±100ppm/°C temperature coefficient) and mechanical requirements (1206 package, 2 terminations, thick film composition). ERJ-8ENF2204V is marked "Not For New Designs" and should only be used for legacy applications.

Q: What is the difference between the substitute parts?

A: All substitute parts are electrically and mechanically equivalent. Differences exist in:

Manufacturer certifications: AC1206FR-072M2L, CRCW12062M20FKEA, ERJ-8ENF2204V, and KTR18EZPF2204 include automotive AEC-Q200 certification
Special features: KTR18EZPF2204 and RCV12062M20FKEA include high-voltage capability
Physical dimensions: Minor variations in length (3.10mm vs 3.20mm) and height (0.60mm to 0.70mm) exist but do not affect PCB footprint compatibility
Inventory availability: Stock levels vary significantly across manufacturers

Q: Are there any compatibility concerns with PCB assembly?

A: No. All substitute parts use the identical 1206 (3216 Metric) package with 2 terminations. Minor dimensional variations (length 3.10-3.20mm, height 0.60-0.70mm) fall within standard PCB design tolerances and do not require layout modifications. All parts are MSL 1 (Unlimited moisture sensitivity), requiring no special handling.

Q: Which substitute should I choose for automotive applications?

A: For automotive applications, select from parts with AEC-Q200 certification: AC1206FR-072M2L, CRCW12062M20FKEA, ERJ-8ENF2204V, or KTR18EZPF2204. KTR18EZPF2204 offers the highest inventory availability (285302 units) and includes high-voltage capability.

Q: Is the RCS3216F225CS still in production?

A: Yes, the RCS3216F225CS is in active production status with 1019 units currently in stock. However, multiple substitute parts from other manufacturers offer higher inventory levels and active production status, providing supply chain flexibility.

Q: What does "Not For New Designs" mean for ERJ-8ENF2204V?

A: This designation indicates that Panasonic has discontinued or is phasing out this part for new product development. While 75183 units are in stock, this part should only be used for maintaining or repairing existing systems that already use this component. For new designs, select from the active production alternatives.
