RC3225F26R7CS Equivalent & Substitute Parts

Part Overview

The RC3225F26R7CS is a 26.7 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 carries ROHS3 compliance certification.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and core performance parameters. The primary substitute listed, ERJ-14NF26R7U from Panasonic Electronic Components, shares identical resistance, tolerance, and package dimensions while offering increased power rating and automotive-grade qualification.

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F26R7CS is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Must Match):

• Resistance value: 26.7 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture Sensitivity Level: MSL 1 or better

Secondary Compatibility Factors (May Exceed):

• Power rating: Substitute parts may have equal or higher power dissipation capability
• RoHS compliance: Substitute parts must meet or exceed regulatory requirements
• Certifications: Additional qualifications (such as AEC-Q200) do not disqualify substitution

The ERJ-14NF26R7U from Panasonic meets all primary criteria while providing enhanced power rating (0.5W versus 0.333W) and automotive-grade AEC-Q200 certification. The increased power rating provides additional thermal margin without affecting circuit performance.

Engineering Selection Recommendations

RC3225F26R7CS (Primary Selection): The RC3225F26R7CS remains the preferred component for new designs. It maintains Active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance satisfies current regulatory requirements for restricted substances. The 0.333W power rating is sufficient for standard signal conditioning and biasing applications within the specified operating temperature range.

ERJ-14NF26R7U (Substitute for Existing Designs): The ERJ-14NF26R7U is suitable as a substitute in existing production or repair scenarios where component availability is constrained. The higher 0.5W power rating provides thermal margin for applications with elevated power dissipation requirements. However, the "Not For New Designs" status and RoHS non-compliance status indicate this part is in end-of-life phase. The RoHS non-compliance requires regulatory assessment before use in new product development or markets with mandatory RoHS requirements.

Selection Criteria:

• Use RC3225F26R7CS for new designs and applications requiring ROHS3 compliance
• Use ERJ-14NF26R7U only when RC3225F26R7CS is unavailable and RoHS compliance is not mandated
• Verify thermal requirements; ERJ-14NF26R7U's higher power rating does not alter circuit behavior but provides additional safety margin

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF26R7U be used as a direct replacement for RC3225F26R7CS?

A: Yes, for applications where RoHS compliance is not required. Both parts share identical resistance (26.7 Ohms), tolerance (±1%), package footprint (1210), and temperature characteristics (±100ppm/°C, -55°C to 155°C). The ERJ-14NF26R7U's higher power rating (0.5W vs. 0.333W) does not affect circuit performance and provides additional thermal capability. However, the ERJ-14NF26R7U carries "Not For New Designs" status and is RoHS non-compliant, requiring regulatory assessment.

Q: What are the physical compatibility considerations?

A: Both parts use the 1210 (3225 Metric) package with nearly identical dimensions. The RC3225F26R7CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" maximum height. The ERJ-14NF26R7U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with 0.028" maximum height. These minor dimensional variations (0.05mm width difference, 0.02mm height difference) are within standard PCB design tolerances and do not affect placement or soldering.

Q: Does the higher power rating of ERJ-14NF26R7U affect circuit operation?

A: No. Power rating specifies the maximum thermal dissipation capability, not the operating power. Both parts will function identically in circuits designed for the RC3225F26R7CS. The ERJ-14NF26R7U simply provides additional thermal margin, which may be beneficial in high-temperature or high-power-density applications.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF26R7U?

A: This designation indicates the part is in end-of-life phase and Panasonic does not recommend its use in new product development. Existing inventory may be available, but long-term supply cannot be guaranteed. For new designs, RC3225F26R7CS is the appropriate selection.

Q: Are there RoHS compliance implications for substitution?

A: Yes. RC3225F26R7CS is ROHS3 compliant, meeting current EU and global regulatory requirements for restricted substances. ERJ-14NF26R7U is RoHS non-compliant. If the application is subject to RoHS mandates (EU markets, automotive, consumer electronics), ERJ-14NF26R7U cannot be used as a substitute without regulatory exemption or market-specific approval.

Q: What is the Moisture Sensitivity Level (MSL) and why is it important?

A: Both parts carry MSL 1 (Unlimited), indicating they require no special moisture control during storage or handling. This simplifies supply chain management and allows standard warehouse conditions without desiccant packaging or controlled humidity environments.
