RC3225F28R0CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F28R0CS is a 28 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 with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range. The RC3225F28R0CS serves as the reference baseline for identifying functionally compatible alternatives from other manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC3225F28R0CS is based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 28 Ohms
• Tolerance: ±1%
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS3 Compliance
• MSL 1 Rating

Power Rating Substitution Rule: Substitute parts with power ratings equal to or greater than 0.333W are acceptable. Higher power ratings provide equivalent or superior thermal performance in the same package footprint.

Identified Substitute Parts:

1. ERJ-P14F28R0U (Panasonic Electronic Components) – Active status, 0.5W rating, AEC-Q200 automotive qualification, pulse withstanding capability
2. ERJ-14NF28R0U (Panasonic Electronic Components) – Not For New Designs status, 0.5W rating, AEC-Q200 automotive qualification

Both substitute parts meet all mandatory electrical and mechanical parameters with enhanced power ratings (0.5W vs. 0.333W).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: ERJ-P14F28R0U

The ERJ-P14F28R0U is the recommended substitute for new designs. This part maintains Active product status, matching the RC3225F28R0CS lifecycle classification. It provides identical electrical specifications with enhanced power rating (0.5W vs. 0.333W), delivering superior thermal margin in the same 1210 package footprint. AEC-Q200 automotive qualification and pulse withstanding capability provide additional robustness for demanding applications. RoHS3 compliance and MSL 1 rating ensure regulatory and handling compatibility.

Secondary Substitute: ERJ-14NF28R0U

The ERJ-14NF28R0U is functionally equivalent but carries Not For New Designs product status. This classification indicates the part is available for existing design support only and should not be selected for new development. Use this substitute only when design continuity with existing inventory is required.

Compliance Verification:

Both substitute parts satisfy RoHS3 and REACH requirements matching the original RC3225F28R0CS. Dimensional variations (height difference of 0.002" / 0.04mm) are within typical PCB assembly tolerances for 1210 package components.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14F28R0U and ERJ-14NF28R0U be used interchangeably with RC3225F28R0CS?

A: Both parts are electrically and mechanically compatible substitutes. They match all mandatory parameters: 28 Ohm resistance, ±1% tolerance, 1210 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The higher power rating (0.5W vs. 0.333W) provides equivalent or superior performance. For new designs, ERJ-P14F28R0U is preferred due to Active product status.

Q: What is the significance of the power rating difference (0.333W vs. 0.5W)?

A: The substitute parts have higher power dissipation capability in the same physical package. This provides additional thermal headroom and does not create compatibility issues. A 0.5W-rated component can safely replace a 0.333W-rated component in any application where the original part was specified.

Q: Are there dimensional compatibility concerns?

A: Substitute parts have minor dimensional variations: width difference of 0.002" (0.05mm) and height difference of 0.002" (0.04mm). These variations are within standard PCB assembly tolerances for 1210 components and do not affect land pattern compatibility or reflow soldering performance.

Q: Why is ERJ-14NF28R0U marked "Not For New Designs"?

A: This product status indicates the part is in mature or declining lifecycle phase. Panasonic continues to supply existing inventory for design continuity, but recommends ERJ-P14F28R0U for new development. Use ERJ-14NF28R0U only when supporting existing designs or when inventory constraints require it.

Q: Do the substitute parts have automotive qualification?

A: Both Panasonic substitutes carry AEC-Q200 automotive qualification. The RC3225F28R0CS does not list automotive qualification. If automotive-grade components are required, the Panasonic substitutes provide this additional certification.

Q: Are packaging formats compatible?

A: The RC3225F28R0CS is supplied in standard packaging. Substitute parts are supplied in Tape & Reel (TR) format. Both formats are compatible with standard SMD assembly equipment. Verify tape specifications with your assembly partner if using automated pick-and-place systems.
