Parameter Comparison

Engineering Selection Recommendations

RC3225F2262CS (Samsung Electro-Mechanics) - Primary Part

Select this part when the original design specification calls for a 0.333W (1/3W) power rating and moisture-resistant thick film construction. The component maintains Active product status and is suitable for new designs. This part is appropriate for general-purpose applications where automotive qualification is not required.

ERJ-P14F2262U (Panasonic Electronic Components) - Preferred Substitute

This part is the recommended substitute for the RC3225F2262CS. It maintains identical electrical specifications (22.6 kOhms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (1210 package, 2 terminations). The ERJ-P14F2262U offers increased power dissipation (0.5W / 1/2W), Automotive AEC-Q200 qualification, and Pulse Withstanding capability. The component retains Active product status, making it suitable for new designs. The marginal increase in seated height (0.028" versus 0.026") remains within typical PCB layout tolerances for 1210 package applications.

ERJ-14NF2262U (Panasonic Electronic Components) - Alternative Substitute

This part provides equivalent electrical and mechanical specifications to ERJ-P14F2262U, including 0.5W power rating and Automotive AEC-Q200 qualification. However, ERJ-14NF2262U carries Not For New Designs product status. This part is suitable only for replacement or legacy system applications where the original design already incorporates this component or where supply constraints necessitate its use.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14F2262U and ERJ-14NF2262U be used interchangeably with RC3225F2262CS?

A: Both Panasonic parts satisfy the electrical and mechanical requirements for substitution. They maintain the same 22.6 kOhms resistance, ±1% tolerance, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are packaged in 1210 (3225 Metric) format with 2 terminations. The primary difference is that ERJ-P14F2262U is Active status while ERJ-14NF2262U is Not For New Designs. For new designs, ERJ-P14F2262U is the appropriate selection.

Q: What is the significance of the higher power rating on the substitute parts?

A: The substitute parts are rated for 0.5W (1/2W) compared to the original 0.333W (1/3W). A higher power rating indicates the component can dissipate more thermal energy without exceeding maximum operating temperature. This enhancement does not affect electrical performance in circuits designed for the original 0.333W specification. The higher rating provides additional thermal margin and is not detrimental to circuit operation.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: The substitute parts have minimal dimensional variations. The length remains 0.126" (3.20mm) for all three parts. Width varies slightly: RC3225F2262CS is 0.100" (2.55mm) while the Panasonic parts are 0.098" (2.50mm). Seated height increases from 0.026" (0.65mm) to 0.028" (0.70mm) on the substitutes. These variations are within standard PCB layout tolerances for 1210 package applications and do not require design modifications.

Q: What does Automotive AEC-Q200 qualification mean for the substitute parts?

A: AEC-Q200 is an automotive industry qualification standard for passive components. This certification indicates the parts have undergone rigorous testing for reliability, temperature cycling, moisture resistance, and other automotive-specific requirements. While the original RC3225F2262CS does not carry this designation, the Panasonic substitutes meet this higher qualification level. This enhancement is beneficial for applications requiring automotive-grade reliability but does not prevent use in non-automotive applications.

Q: Why is ERJ-P14F2262U recommended over ERJ-14NF2262U?

A: ERJ-P14F2262U maintains Active product status, indicating it is approved for new designs and will remain in production. ERJ-14NF2262U carries Not For New Designs status, which signals potential future discontinuation. For applications requiring long-term component availability and design flexibility, ERJ-P14F2262U is the appropriate selection. ERJ-14NF2262U is suitable only for replacement applications or legacy systems.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC3225F2262CS, ERJ-14NF2262U, and ERJ-P14F2262U are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). This ensures compatibility with modern manufacturing processes and environmental regulations across all three options.

Q: What is Pulse Withstanding capability on ERJ-P14F2262U?

A: Pulse Withstanding is an additional feature indicating the component can tolerate transient overvoltage or overcurrent pulses without degradation. This capability enhances reliability in circuits subject to electrical transients or switching events. The original RC3225F2262CS does not specify this feature, but its presence on ERJ-P14F2262U provides additional protection without affecting standard circuit operation.
