Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F2671CS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance value: 2.67 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 1210 (3225 Metric) (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power rating than the main part (0.333W minimum)
• Physical dimensions: Minor variations within standard 1210 package tolerances are acceptable
• Packaging format: May differ (bulk, tape & reel, etc.)
• Product status: May differ between Active and Not For New Designs
• Certifications: May include additional certifications (e.g., AEC-Q200)

The ERJ-14NF2671U qualifies as a substitute because it maintains identical resistance, tolerance, package, temperature coefficient, and operating temperature range. The power rating of 0.5W (1/2W) exceeds the minimum requirement of 0.333W, making it suitable for applications where the main part is specified.

Parameter Comparison

Engineering Selection Recommendations

RC3225F2671CS (Main Part): The RC3225F2671CS is the primary selection for new designs. It carries Active product status, indicating ongoing manufacturer support and availability. This part is suitable for applications requiring standard 1/3W thick film resistor performance with moisture resistance and unlimited moisture sensitivity level handling.

ERJ-14NF2671U (Substitute): The ERJ-14NF2671U is electrically and mechanically compatible with the RC3225F2671CS. However, this part carries Not For New Designs status, indicating it is intended for legacy system support and replacement applications only. The higher power rating (0.5W vs. 0.333W) provides additional thermal margin in existing designs. The inclusion of AEC-Q200 automotive qualification in the ERJ-14NF2671U indicates suitability for automotive applications, though this certification is not required for general-purpose use.

Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Selection between these parts should be based on design phase (new vs. legacy) and application requirements rather than electrical performance, as both meet the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF2671U be used as a direct replacement for the RC3225F2671CS in existing designs?

A: Yes. The ERJ-14NF2671U meets all critical electrical parameters: 2.67 kOhms resistance, ±1% tolerance, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The 1210 package dimensions are compatible within standard tolerances. The higher power rating (0.5W) does not create compatibility issues in applications designed for 0.333W components.

Q: Why does the ERJ-14NF2671U have a higher power rating than the RC3225F2671CS?

A: Power rating differences reflect manufacturer design specifications and thermal management approaches. A higher power rating indicates the component can dissipate more heat without exceeding temperature limits. This does not affect substitution suitability; components with higher power ratings are acceptable replacements in applications specified for lower ratings.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF2671U?

A: This status indicates the manufacturer is not recommending this part for new product development. It remains available for legacy system support and replacement of existing components. For new designs, the RC3225F2671CS (Active status) is the appropriate selection.

Q: Are there dimensional differences between these parts that affect PCB layout?

A: Minor dimensional variations exist within standard 1210 package tolerances. The RC3225F2671CS measures 0.126" L x 0.100" W with 0.026" maximum height, while the ERJ-14NF2671U measures 0.126" L x 0.098" W with 0.028" maximum height. These differences are within standard 1210 package specifications and do not require PCB layout modifications.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the RC3225F2671CS and ERJ-14NF2671U are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8533.21.0030. The ERJ-14NF2671U includes additional AEC-Q200 automotive qualification, which is not present in the RC3225F2671CS but does not create incompatibility.

Q: What determines whether a part qualifies as a substitute for the RC3225F2671CS?

A: Substitution is determined by exact matching of resistance value, tolerance, package type, temperature coefficient, and operating temperature range. Power rating may be equal or higher. All other parameters, including certifications and product status, may vary without affecting substitution eligibility.
