RCS3216J225CS

Part Overview

The RCS3216J225CS is a 2.2 MOhms ±5% 0.25W (1/4W) thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component features anti-sulfur and moisture-resistant construction with an operating temperature range of -55°C to 155°C and is ROHS3 compliant. Substitute parts are necessary to address supply availability, performance tolerance requirements, or application-specific certifications such as automotive AEC-Q200 qualification or high-voltage capability.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216J225CS is determined by the following core parameters: resistance value (2.2 MOhms), package format (1206/3216 Metric), power rating (0.25W), composition (thick film), and operating temperature range (-55°C to 155°C). All listed substitutes maintain these electrical and mechanical characteristics. Tolerance variations (±5% vs. ±1%) represent tighter specifications in substitute options and do not preclude interchangeability. Differences in features such as automotive AEC-Q200 certification, high-voltage capability, or anti-sulfur treatment indicate enhanced performance attributes that are application-dependent but do not affect basic electrical compatibility within the defined parameter set.

Engineering Selection Recommendations

For new designs, select from parts with Active product status: AC1206FR-072M2L, CRCW12062M20FKEA, KTR18EZPF2204, RC1206FR-072M2L, RC1206JR-072M2L, and RCV12062M20FKEA. The ERJ-8ENF2204V carries a "Not For New Designs" designation and should not be used in new circuit development.

For automotive applications requiring AEC-Q200 certification, use AC1206FR-072M2L, CRCW12062M20FKEA, or KTR18EZPF2204. The KTR18EZPF2204 additionally provides high-voltage capability and is recommended for applications exceeding standard voltage requirements. The RCV12062M20FKEA offers high-voltage performance without automotive certification.

RC1206JR-072M2L provides tolerance matching (±5%) to the original RCS3216J225CS, while all other substitutes offer improved tolerance of ±1%, suitable for circuits requiring tighter resistance specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS3216J225CS with a ±1% tolerance part? A: Yes. All substitute parts marked as Active status with ±1% tolerance are electrically compatible. The tighter tolerance represents improved component specification and does not affect basic circuit functionality where ±5% tolerance was previously acceptable.

Q: Which substitute is best for automotive applications? A: AC1206FR-072M2L, CRCW12062M20FKEA, and KTR18EZPF2204 all carry AEC-Q200 automotive qualification. KTR18EZPF2204 additionally provides high-voltage rating. Selection depends on availability and voltage requirements of your specific circuit.

Q: Does package size differ between the main part and substitutes? A: All parts maintain the 1206 (3216 Metric) package format. Minor dimensional variations (length 3.10mm to 3.20mm, height 0.60mm to 0.70mm) do not affect PCB assembly compatibility as these fall within standard SMD placement tolerances.

Q: Is RCS3216J225CS discontinued? A: No. RCS3216J225CS maintains Active product status with 882 units in stock. Substitutes are listed to provide alternative sourcing options and enhanced specifications for specific application requirements.

Q: What is the difference between "Anti-Sulfur" and standard Moisture Resistant features? A: Anti-sulfur treatment specifically protects against hydrogen sulfide corrosion in high-pollution industrial environments. Standard moisture-resistant construction addresses general environmental protection. Application environment determines which feature is necessary.

Q: Can I use ERJ-8ENF2204V in new designs? A: No. ERJ-8ENF2204V carries a "Not For New Designs" status. Use an Active-status substitute for new circuit development.
