RC3225F17R4CS Equivalent & Substitute Parts

Part Overview

The RC3225F17R4CS is a 17.4 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 is designed for moisture-resistant applications across 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.

Equivalent and substitute parts are identified to provide design flexibility when the primary part is unavailable, when higher power ratings are required, or when specific automotive certifications are necessary for application requirements.

Substitute Part Grouping Explanation

Substitute parts for the RC3225F17R4CS are identified based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Resistance value: 17.4 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package format: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Compliance: ROHS3 (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

Secondary Consideration:

• Power Rating: Substitute parts may have equal or higher power ratings (0.5W or greater) while maintaining all other parameters

All substitute parts listed meet these criteria and are electrically and mechanically compatible with the RC3225F17R4CS in applications where the specified parameters are required.

Engineering Selection Recommendations

AC1210FR-0717R4L (YAGEO) - Upgrade Substitute: This part is recommended as the primary substitute for new designs and production applications. It maintains Active product status, meets all electrical and mechanical parameters of the RC3225F17R4CS, and provides a higher power rating of 0.5W. The part carries AEC-Q200 automotive certification and moisture-resistant thick film construction, making it suitable for demanding automotive and industrial applications. ROHS3 compliance and MSL 1 rating ensure compatibility with modern manufacturing processes.

ERJ-14NF17R4U (Panasonic) - Similar Substitute: This part meets all core electrical and mechanical parameters and provides equivalent 0.5W power rating. However, the part carries a "Not For New Designs" product status designation. This part is suitable for replacement and maintenance applications where existing inventory or legacy system compatibility is required. AEC-Q200 automotive certification is provided. Use of this part in new designs is not recommended due to its discontinued status.

For applications requiring the exact original specification with Active product status and no automotive requirements, the RC3225F17R4CS remains the primary choice. For new designs requiring automotive qualification or higher power dissipation capability, AC1210FR-0717R4L is the recommended substitute.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-0717R4L be used as a direct replacement for RC3225F17R4CS?

A: Yes. AC1210FR-0717R4L is electrically and mechanically compatible with RC3225F17R4CS. Both parts share identical resistance (17.4 Ohms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance ratings (ROHS3, MSL 1). The substitute part provides higher power rating (0.5W versus 0.333W), which does not create compatibility issues in applications designed for the original part.

Q: What is the difference between the RC3225F17R4CS and ERJ-14NF17R4U?

A: Both parts are electrically equivalent with identical resistance, tolerance, package, composition, and temperature specifications. The primary difference is product status: RC3225F17R4CS is Active, while ERJ-14NF17R4U is designated "Not For New Designs." Both provide 0.5W power rating and AEC-Q200 automotive certification (ERJ-14NF17R4U only). The RC3225F17R4CS includes moisture-resistant specification, while ERJ-14NF17R4U does not specify this feature.

Q: Are there any package dimension differences between these parts?

A: All three parts use the 1210 (3225 Metric) package format. Minor dimensional variations exist within standard tolerances: RC3225F17R4CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" max height; AC1210FR-0717R4L measures 0.122" L x 0.102" W (3.10mm x 2.60mm) with 0.024" max height; ERJ-14NF17R4U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with 0.028" max height. These variations remain within standard 1210 package specifications and do not affect PCB layout or assembly compatibility.

Q: Which substitute part should be selected for automotive applications?

A: AC1210FR-0717R4L is the recommended choice for automotive applications. This part carries AEC-Q200 automotive qualification and maintains Active product status. ERJ-14NF17R4U also provides AEC-Q200 certification but is designated "Not For New Designs." The RC3225F17R4CS does not specify automotive certification.

Q: What is the significance of the MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. This rating applies to all three parts and simplifies inventory management and supply chain logistics without requiring specialized dry-pack storage or time-limited shelf life tracking.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the constraints of the original design specifications. All three parts meet the core electrical parameters (17.4 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C). The substitute parts provide equal or higher power ratings, which does not create compatibility issues. Designs originally specified for 0.333W operation will function correctly with 0.5W rated substitutes. Verify that any automotive or moisture-resistant requirements in the original design are met by the selected substitute.
