RC3225F1652CS Equivalent & Substitute Parts

Part Overview

The RC3225F1652CS is a 16.5 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 845 units available. The part is designed for general-purpose applications requiring moisture-resistant thick film construction with standard tolerance specifications.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the critical parameters that define this resistor category. The primary substitute identified is the ERJ-14NF1652U from Panasonic Electronic Components, which shares the same resistance value, tolerance, package size, and operating temperature range, though with different power rating and product status classifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F1652CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 16.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 1210 (3225 Metric) (exact match required for PCB compatibility)
• Composition: Thick Film (exact match required for electrical behavior)
• Temperature Coefficient: ±100ppm/°C (exact match required for stability characteristics)
• Operating Temperature Range: -55°C to 155°C (exact match required for environmental limits)

Flexible Parameters:

• Power Rating: The substitute may have equal or higher power rating without affecting functionality in applications designed for the original 0.333W specification
• Packaging Format: Original part uses standard packaging; substitutes may use different packaging formats (Tape & Reel) without affecting electrical performance
• Product Status: Substitutes with different product status classifications (such as "Not For New Designs") may be used in existing designs or legacy applications

The ERJ-14NF1652U from Panasonic meets all mandatory matching parameters and qualifies as a direct electrical substitute, with the distinction that it carries a higher power rating (0.5W vs. 0.333W) and is designated as "Not For New Designs."

Parameter Comparison

Engineering Selection Recommendations

For Active Product Selection: The RC3225F1652CS maintains Active product status, indicating ongoing manufacturer support and availability. This part is suitable for new designs requiring a 16.5 kOhms ±1% resistor in 1210 package format with 0.333W power rating and moisture-resistant thick film construction.

For Substitute Selection: The ERJ-14NF1652U from Panasonic qualifies as an electrical equivalent based on matching resistance, tolerance, package, composition, temperature coefficient, and operating temperature range. However, this part carries "Not For New Designs" status, restricting its use to legacy applications, existing design revisions, or situations where supply continuity of the primary part is unavailable.

Compliance Considerations: Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring regulatory alignment and simplified handling requirements. Both parts carry identical ECCN (EAR99) and HTSUS classifications.

Power Rating Consideration: The ERJ-14NF1652U is rated at 0.5W compared to the RC3225F1652CS at 0.333W. In applications where the circuit design dissipates power within the 0.333W specification, the higher-rated substitute provides additional thermal margin without affecting electrical performance. Conversely, if the application requires the exact 0.333W specification for thermal management purposes, the substitute's higher rating must be evaluated against circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF1652U directly replace the RC3225F1652CS on a PCB?

A: Yes, from a mechanical and electrical standpoint. Both parts use the 1210 (3225 Metric) package with functionally equivalent dimensions (length 3.20mm, width within 0.05mm tolerance, height within 0.04mm tolerance). The footprint compatibility is maintained. However, the substitute's "Not For New Designs" status should be considered for long-term supply planning.

Q: What does "Not For New Designs" mean for the ERJ-14NF1652U?

A: This designation indicates that Panasonic does not recommend this part for new product development. It may be used in existing designs, legacy applications, or as a temporary substitute when the primary part is unavailable. For new designs, the RC3225F1652CS (Active status) is the preferred selection.

Q: Are there differences in electrical performance between these two parts?

A: No. Both parts share identical resistance (16.5 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is power rating: the substitute is rated 0.5W versus the original 0.333W. This difference does not affect electrical performance in circuits designed for the lower power specification.

Q: Does the higher power rating of the ERJ-14NF1652U affect circuit behavior?

A: No. A higher power rating indicates greater thermal capacity and does not change the resistor's electrical characteristics (resistance value, tolerance, frequency response, or temperature coefficient). The substitute will function identically in the circuit.

Q: What is the significance of MSL Level 1 (Unlimited) for both parts?

A: MSL Level 1 indicates the lowest moisture sensitivity classification. Both parts can be stored and handled without special moisture control measures, simplifying inventory management and reducing handling costs compared to higher MSL-rated components.

Q: Are both parts RoHS compliant?

A: Yes. Both the RC3225F1652CS and ERJ-14NF1652U are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the difference between the packaging formats listed?

A: The RC3225F1652CS uses standard packaging, while the ERJ-14NF1652U is supplied in Tape & Reel (TR) format. Tape & Reel packaging is designed for automated assembly processes and typically offers cost advantages for high-volume production. Both formats contain the same electrical component; the difference is in delivery and handling method.

Q: Can I use the ERJ-14NF1652U in a design currently using the RC3225F1652CS?

A: Yes, provided the application does not depend on the specific 0.333W power rating for thermal management. The electrical specifications are identical, and the package dimensions are functionally equivalent. Verify that your assembly process can accommodate the Tape & Reel format if that is the available packaging option.
