RC3225F16R9CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F16R9CS is a 16.9 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) power dissipation in a 1210 (3225 Metric) surface mount package. This component is classified as Active product status and features moisture-resistant construction suitable for general industrial applications.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint. The RC3225F16R9CS may require alternatives due to inventory availability, supply chain considerations, or application-specific requirements such as automotive qualification or higher power ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F16R9CS is determined by the following mandatory parameters:

Electrical Compatibility Requirements:

• Resistance value: 16.9 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Mechanical Compatibility Requirements:

• Package / Case: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• Moisture Sensitivity Level: MSL 1 (mandatory)

Substitute parts identified in this reference maintain all mandatory electrical and mechanical parameters. Power rating variations are permitted when the substitute part meets or exceeds the original specification, provided all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

RMCF1210FT16R9 (Stackpole Electronics Inc): This substitute part is classified as Active product status and maintains full electrical and mechanical compatibility with the RC3225F16R9CS. The RMCF1210FT16R9 features a higher power rating of 0.5W (1/2W) compared to the original 0.333W specification, providing additional thermal margin in applications. AEC-Q200 automotive qualification is included. Dimensional variation in width (2.50mm vs 2.55mm) and height (0.70mm vs 0.66mm) remains within standard PCB layout tolerances for 1210 package footprints. This part is suitable for new designs.

ERJ-14NF16R9U (Panasonic Electronic Components): This substitute part maintains full electrical and mechanical compatibility with the RC3225F16R9CS and includes AEC-Q200 automotive qualification. However, this part is classified as Not For New Designs. The ERJ-14NF16R9U features a 0.5W (1/2W) power rating. Dimensional specifications match the RMCF1210FT16R9. This part is suitable only for replacement or legacy system applications where automotive qualification is required.

Selection Basis:

• All substitute parts maintain the mandatory electrical parameters: 16.9 Ohms ±1%, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range
• All substitute parts are housed in the 1210 (3225 Metric) package with identical footprint compatibility
• All substitute parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating
• Power rating increases in substitute parts do not create incompatibility; higher power ratings provide design margin
• Product status and automotive qualification are secondary selection criteria based on application requirements

Frequently Asked Questions (FAQ)

Q: Can the RMCF1210FT16R9 directly replace the RC3225F16R9CS in existing designs?

A: Yes. The RMCF1210FT16R9 maintains identical electrical specifications (16.9 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C) and package footprint (1210 / 3225 Metric). The higher power rating (0.5W vs 0.333W) does not create incompatibility. Dimensional variations (width 2.50mm vs 2.55mm, height 0.70mm vs 0.66mm) are within standard PCB layout tolerances for this package class.

Q: What is the difference between the RC3225F16R9CS and the substitute parts in terms of power dissipation?

A: The RC3225F16R9CS is rated at 0.333W (1/3W). Both substitute parts (RMCF1210FT16R9 and ERJ-14NF16R9U) are rated at 0.5W (1/2W). Higher power ratings indicate greater thermal capacity and do not restrict substitution in applications designed for the lower rating.

Q: Are the substitute parts suitable for automotive applications?

A: The RMCF1210FT16R9 and ERJ-14NF16R9U both carry AEC-Q200 automotive qualification. The RC3225F16R9CS does not specify automotive qualification. If automotive qualification is required, either substitute part is suitable. If automotive qualification is not required, the RC3225F16R9CS remains the original specification.

Q: Why is the ERJ-14NF16R9U marked as "Not For New Designs"?

A: Product status classification is determined by the manufacturer. The ERJ-14NF16R9U is suitable for replacement applications and legacy system support but should not be selected for new product development. The RMCF1210FT16R9, classified as Active, is the preferred substitute for new designs.

Q: Are there any moisture sensitivity or RoHS compliance differences between these parts?

A: No. All three parts (RC3225F16R9CS, RMCF1210FT16R9, and ERJ-14NF16R9U) are classified as MSL 1 (Unlimited moisture sensitivity) and ROHS3 Compliant. Moisture handling and environmental compliance are equivalent across all parts.

Q: What is the significance of the ±100ppm/°C temperature coefficient specification?

A: The temperature coefficient indicates resistance value drift over the operating temperature range. All three parts maintain ±100ppm/°C, meaning resistance variation remains within ±0.169 Ohms across the -55°C ~ 155°C operating range. This specification is identical across all parts and does not affect substitution eligibility.

Q: Can these parts be used interchangeably in tape and reel packaging?

A: The RC3225F16R9CS is specified with "-" packaging notation (packaging type not explicitly defined in available data). The RMCF1210FT16R9 and ERJ-14NF16R9U are both supplied in Tape & Reel (TR) packaging. Verify packaging requirements with your procurement specification before substitution.
