RC3225F1623CS Equivalent & Substitute Parts

Part Overview

The RC3225F1623CS is a 162 kOhms ±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 operates across the temperature range of -55°C to 155°C. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary manufacturer part is unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits selection from qualified alternatives meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F1623CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 162 kOhms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Power rating: The substitute part ERJ-14NF1623U is rated at 0.5W (1/2W), which exceeds the 0.333W requirement of the main part. Higher power ratings are acceptable in substitution as they provide equal or greater thermal capability within the same package footprint.

The ERJ-14NF1623U from Panasonic Electronic Components meets all mandatory parameters and provides enhanced power dissipation capability. This part is qualified to AEC-Q200 automotive standards, though it carries a "Not For New Designs" product status designation.

Parameter Comparison

Engineering Selection Recommendations

RC3225F1623CS (Samsung Electro-Mechanics): This part maintains Active product status, indicating ongoing manufacturer support and continued availability. Selection of this part is appropriate for new designs and applications requiring long-term supply assurance. The component carries full RoHS3 compliance and unlimited moisture sensitivity rating, suitable for standard industrial and commercial applications.

ERJ-14NF1623U (Panasonic Electronic Components): This substitute part carries a "Not For New Designs" designation, indicating that Panasonic has discontinued active development and marketing of this component. However, the part remains electrically and mechanically compatible with the RC3225F1623CS. The ERJ-14NF1623U includes AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. The higher power rating (0.5W versus 0.333W) provides additional thermal margin. This part should be selected only when existing inventory is available and supply continuity is not a primary concern, or when automotive qualification is a specific design requirement.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1623U be used as a direct replacement for RC3225F1623CS?

A: Yes. Both parts share identical resistance value (162 kOhms), tolerance (±1%), package format (1210/3225 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The ERJ-14NF1623U has a higher power rating (0.5W versus 0.333W), which is acceptable in substitution as it provides equal or greater thermal capability.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF1623U?

A: This designation indicates that Panasonic has discontinued active development and marketing of this part number. While the component remains electrically and mechanically compatible, it may have limited future availability. New designs should prioritize the RC3225F1623CS or other Active-status alternatives to ensure long-term supply continuity.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The RC3225F1623CS 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-14NF1623U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with a maximum seated height of 0.028" (0.70mm). These differences are within typical PCB layout tolerances for 1210 package components and do not affect interchangeability.

Q: Does the ERJ-14NF1623U require different handling or storage procedures?

A: Both parts share identical Moisture Sensitivity Level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling. Standard ESD precautions and dry storage conditions apply to both components.

Q: What is the advantage of the higher power rating on the ERJ-14NF1623U?

A: The 0.5W rating on the ERJ-14NF1623U provides additional thermal margin compared to the 0.333W rating of the RC3225F1623CS. In applications where the resistor dissipates power near its rated limit, the higher power rating reduces operating temperature and extends component life. However, if the application requires only 0.333W dissipation, both parts perform identically.

Q: Is AEC-Q200 qualification required for my application?

A: AEC-Q200 qualification is specific to automotive applications requiring automotive-grade reliability standards. The RC3225F1623CS does not carry this qualification. If your application requires AEC-Q200 compliance, the ERJ-14NF1623U is qualified. If automotive qualification is not required, both parts are suitable.
