RC3225F9311CS Equivalent & Substitute Parts

Part Overview

The RC3225F9311CS is a 9.31 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) in a 1210 (3225 Metric) package. This component is classified as Active product status and is currently in stock with 751 pieces available.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative specifications within the same electrical and mechanical parameters. The RC3225F9311CS has one identified equivalent substitute that maintains the same resistance value and tolerance while offering different power rating and packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F9311CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 9.31 kOhms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2

Allowable Variation Parameters:

• Power Rating: May be equal to or greater than 0.333W
• Packaging format: May differ (bulk, tape & reel)
• Manufacturer: Different manufacturer acceptable
• Product Status: May vary
• Certifications: Additional certifications acceptable

The identified substitute ERJ-14NF9311U meets all mandatory matching parameters while offering a higher power rating (0.5W vs. 0.333W) and automotive-grade certification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

Primary Component (RC3225F9311CS): The RC3225F9311CS is the preferred selection for new designs. It maintains Active product status, ensuring long-term availability and manufacturer support. The component is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Substitute Component (ERJ-14NF9311U): The ERJ-14NF9311U is electrically and mechanically compatible with the RC3225F9311CS for applications where the higher power rating (0.5W vs. 0.333W) is acceptable or beneficial. This substitute is suitable for existing designs requiring component replacement or supply alternatives. However, the ERJ-14NF9311U carries a "Not For New Designs" status, indicating that Panasonic does not recommend this part for new product development. The AEC-Q200 automotive certification of the ERJ-14NF9311U provides additional qualification for automotive applications if required.

Selection Criteria:

• Use RC3225F9311CS for new designs and applications requiring long-term component availability
• Use ERJ-14NF9311U only as a substitute in existing designs or when supply of the primary component is unavailable
• Verify that the higher power rating of the ERJ-14NF9311U does not introduce thermal or performance concerns in the target application
• Account for minor dimensional variations (height difference of 0.002" / 0.04mm) in PCB layout if space constraints exist

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF9311U be used as a direct replacement for RC3225F9311CS?

A: Yes, the ERJ-14NF9311U is electrically and mechanically compatible. Both components share identical resistance (9.31 kOhms), tolerance (±1%), package (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The ERJ-14NF9311U has a higher power rating (0.5W vs. 0.333W), which is acceptable for substitution in applications where the original power rating is sufficient.

Q: What are the dimensional differences between these parts?

A: The RC3225F9311CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with a maximum seated height of 0.026" (0.66mm). The ERJ-14NF9311U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with a maximum seated height of 0.028" (0.70mm). The length is identical, width differs by 0.002" (0.05mm), and height differs by 0.002" (0.04mm). These variations are within standard PCB layout tolerances for 1210 package components.

Q: Why is ERJ-14NF9311U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued active promotion and development support for this part number. New designs should prioritize the RC3225F9311CS or other active product alternatives. The ERJ-14NF9311U remains available for existing design support and component replacement scenarios.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and REACH unaffected. The ERJ-14NF9311U carries additional AEC-Q200 automotive qualification, which is not specified for the RC3225F9311CS. If automotive-grade certification is required, the ERJ-14NF9311U provides this qualification.

Q: What packaging formats are available?

A: The RC3225F9311CS is supplied in bulk packaging. The ERJ-14NF9311U is supplied in Tape & Reel (TR) format. Packaging selection depends on manufacturing volume and assembly process requirements.

Q: Can the higher power rating of ERJ-14NF9311U cause issues?

A: No. A higher power rating is a conservative substitution. The ERJ-14NF9311U will dissipate power at the same or lower levels as the RC3225F9311CS in identical circuit conditions. The higher rating provides additional thermal margin and does not introduce performance concerns.
