RCS3216F4422CS Equivalent & Substitute Parts

Part Overview

The RCS3216F4422CS is a 44.2 kOhms ±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 currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings are maintained across alternative manufacturers.

Substitute Part Grouping Explanation

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

Electrical Equivalence: Resistance value (44.2 kOhms), tolerance (±1%), and power rating (0.25W) must be identical.

Mechanical Compatibility: Package designation (1206 / 3216 Metric), physical dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm), and termination count (2) must match.

Environmental Performance: Temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), composition (Thick Film), and moisture sensitivity level (MSL 1) must be maintained.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are required for all substitutes.

All four substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RCS3216F4422CS.

Engineering Selection Recommendations

Primary Selection (Active Production): CR1206-FX-4422ELF (Bourns Inc.), CRCW120644K2FKEA (Vishay Dale), and RC1206FR-0744K2L (YAGEO) are all active products with full production support. These three parts are recommended for new designs and ongoing production applications.

Secondary Selection (Legacy Status): ERJ-8ENF4422V (Panasonic Electronic Components) carries a "Not For New Designs" status. This part remains available with substantial inventory but should be reserved for legacy system maintenance or replacement applications only.

Automotive Applications: CRCW120644K2FKEA and ERJ-8ENF4422V both carry AEC-Q200 automotive qualification. These parts are suitable for automotive-grade applications where this certification is required.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the RCS3216F4422CS.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-4422ELF replace RCS3216F4422CS in existing designs?

A: Yes. Both parts share identical electrical specifications (44.2 kOhms ±1%, 0.25W), mechanical package (1206), temperature performance (±100ppm/°C, -55°C to 155°C), and regulatory compliance (ROHS3, MSL 1). The maximum seated height difference (0.030" vs 0.026") is within typical PCB design tolerances for 1206 components.

Q: What is the difference between the Bourns and Vishay Dale versions?

A: Both CR1206-FX-4422ELF (Bourns) and CRCW120644K2FKEA (Vishay Dale) are electrically equivalent. The Vishay part includes AEC-Q200 automotive qualification and has a lower maximum seated height (0.024" vs 0.030"). Selection depends on automotive requirement and available board space.

Q: Why is ERJ-8ENF4422V marked "Not For New Designs"?

A: This designation indicates Panasonic has transitioned this product line. While the part remains available and functionally equivalent, it should not be selected for new product development. Use CR1206-FX-4422ELF, CRCW120644K2FKEA, or RC1206FR-0744K2L for new designs.

Q: Are all substitutes available in Tape & Reel packaging?

A: Yes. All four substitute parts are supplied in Tape & Reel (TR) format, matching standard SMD assembly requirements.

Q: Does the RCS3216F4422CS have anti-sulfur protection that substitutes lack?

A: The RCS3216F4422CS specifies anti-sulfur and moisture-resistant features. The substitute parts specify moisture-resistant properties. Verify anti-sulfur requirements with application specifications before substitution in high-sulfur environments.
