RC3225F19R6CS Equivalent & Substitute Parts

Part Overview

The RC3225F19R6CS is a 19.6 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation and features moisture-resistant construction with an operating temperature range of -55°C to 155°C. The part maintains Active product status and is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent resistance values, tolerance specifications, and package dimensions align with the original component, enabling direct replacement in circuit applications where the electrical and mechanical parameters remain compatible.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F19R6CS are qualified based on the following critical parameters:

Matching Parameters (Required for Substitution):

• Resistance value: 19.6 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL 1 rating

Variable Parameters (Allowed to Differ):

• Power rating (0.333W vs. 0.5W)
• Manufacturer and series designation
• Packaging format (bulk vs. Tape & Reel)
• Additional certifications (AEC-Q200)
• Product status (Active vs. Not For New Designs)
• Physical dimensions (minor variations within package specification)

The identified substitutes maintain electrical equivalence while offering higher power ratings or automotive-grade certifications, making them suitable for applications where the original part is unavailable or where enhanced specifications are beneficial.

Parameter Comparison

Engineering Selection Recommendations

CRCW121019R6FKEA (Vishay Dale) is the primary substitute option. This part maintains Active product status, carries AEC-Q200 automotive qualification, and provides a higher power rating (0.5W vs. 0.333W) while preserving all critical electrical parameters. The increased power rating offers design margin without compromising compatibility. RoHS3 compliance and MSL 1 rating align with the original specification.

ERJ-14NF19R6U (Panasonic Electronic Components) is a secondary substitute option. While electrically equivalent and AEC-Q200 certified, this part carries a "Not For New Designs" product status designation. This classification indicates the manufacturer is phasing out the component in favor of newer alternatives. Use of this part is acceptable for legacy system maintenance or replacement applications but is not recommended for new product development.

Both substitutes are electrically and mechanically compatible with the RC3225F19R6CS. Selection between them depends on product lifecycle requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can CRCW121019R6FKEA replace RC3225F19R6CS in existing designs?

A: Yes. Both parts share identical resistance (19.6 Ohms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The CRCW121019R6FKEA provides higher power rating (0.5W vs. 0.333W), which is compatible with applications designed for the original part.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF19R6U?

A: This designation indicates that Panasonic has discontinued active development and marketing of this component. While the part remains electrically and mechanically equivalent, it is intended for replacement and maintenance of existing systems only. New product designs should prioritize parts with Active status, such as CRCW121019R6FKEA or RC3225F19R6CS.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist within the 1210 package specification. RC3225F19R6CS has a maximum seated height of 0.026" (0.66mm), while CRCW121019R6FKEA measures 0.024" (0.60mm) and ERJ-14NF19R6U measures 0.028" (0.70mm). These variations remain within standard 1210 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Do the substitute parts require different handling or storage procedures?

A: No. All three parts share MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control measures are required during storage or handling. Standard component storage conditions apply to all parts.

Q: What is the advantage of AEC-Q200 certification on the substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. CRCW121019R6FKEA and ERJ-14NF19R6U carry this certification, indicating compliance with automotive reliability and quality requirements. This certification is beneficial for applications requiring automotive-grade components but does not affect compatibility with non-automotive applications.

Q: Can I use a higher power-rated substitute in a circuit designed for 0.333W?

A: Yes. A component rated for higher power dissipation (0.5W) can be used in applications designed for lower power (0.333W). The higher rating provides additional thermal margin and does not negatively impact circuit performance. The component will operate within its rated specifications.
