RC3225F2802CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F2802CS is a 28 kOhms ±1% 0.333W (1/3W) chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is currently Active in product status and ROHS3 compliant with MSL 1 rating.

Substitute parts are identified when equivalent electrical specifications (resistance value, tolerance, temperature coefficient, operating range) and mechanical compatibility (package size, termination count) are maintained, while power rating may be upgraded for enhanced thermal performance in demanding applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F2802CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance Value: 28 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)
• Number of Terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Allowable Variation:

• Power Rating: Upgrade from 0.333W (1/3W) to 0.5W (1/2W) is permissible, as higher power dissipation capability maintains backward compatibility with circuits designed for the lower rating.

Compliance Requirements:

• RoHS3 Compliance (maintained across all substitutes)
• MSL 1 Rating (maintained across all substitutes)

All four substitute parts listed meet these criteria and are electrically and mechanically interchangeable with the RC3225F2802CS.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: AC1210FR-0728KL (YAGEO), ERJ-P14F2802U (Panasonic), and RMCF1210FT28K0 (Stackpole) are all Active products suitable for new design implementations. All three offer upgraded 0.5W power ratings with AEC-Q200 automotive qualification, providing enhanced thermal margin over the original RC3225F2802CS specification.

For Existing Production / Replacement: All four substitute parts maintain full electrical and mechanical compatibility with the RC3225F2802CS. The power rating upgrade from 0.333W to 0.5W across three of the four substitutes does not introduce incompatibility; circuits designed for 0.333W operation function correctly with higher-rated components.

Product Status Consideration: ERJ-14NF2802U (Panasonic) carries a "Not For New Designs" status. While electrically and mechanically equivalent, this part should be reserved for legacy system maintenance and replacement applications only. For new development, select from AC1210FR-0728KL, ERJ-P14F2802U, or RMCF1210FT28K0.

Automotive Applications: All substitute parts include AEC-Q200 automotive qualification. The original RC3225F2802CS does not specify automotive rating. If automotive compliance is required, any of the four substitutes satisfy this requirement.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-0728KL replace RC3225F2802CS in existing circuits?

A: Yes. AC1210FR-0728KL is electrically and mechanically equivalent. The 0.5W power rating (versus 0.333W original) represents a capability upgrade that maintains backward compatibility. Physical dimensions remain within acceptable tolerance for PCB footprint compatibility.

Q: What is the difference between ERJ-14NF2802U and ERJ-P14F2802U?

A: Both are 28 kOhms ±1% 0.5W 1210 thick film resistors with identical electrical specifications and operating ranges. ERJ-P14F2802U includes pulse withstanding capability and carries Active product status. ERJ-14NF2802U is marked "Not For New Designs." For new applications, ERJ-P14F2802U is the preferred Panasonic option.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All four substitute parts (AC1210FR-0728KL, ERJ-14NF2802U, ERJ-P14F2802U, RMCF1210FT28K0) are ROHS3 compliant with MSL 1 rating, matching the original RC3225F2802CS specification.

Q: Does the 0.5W power upgrade affect circuit performance?

A: No. Higher power rating indicates greater thermal dissipation capability. Circuits designed for 0.333W operation experience no functional change when populated with 0.5W-rated components. Thermal performance improves, reducing junction temperature under identical load conditions.

Q: Can I use ERJ-14NF2802U in production?

A: ERJ-14NF2802U is electrically and mechanically suitable for replacement and maintenance of existing systems. However, its "Not For New Designs" status indicates Panasonic does not recommend this part for new product development. For ongoing production, AC1210FR-0728KL, ERJ-P14F2802U, or RMCF1210FT28K0 are preferred.

Q: Are package dimensions identical across all parts?

A: Package designation (1210 / 3225 Metric) is identical. Dimensional tolerances vary slightly: RC3225F2802CS measures 0.126" L × 0.100" W; substitutes range 0.122–0.126" L × 0.098–0.102" W. All dimensions fall within standard 1210 package tolerance and are PCB footprint compatible.

Q: Which substitute offers the best availability?

A: ERJ-14NF2802U shows highest inventory (12,508 pcs). ERJ-P14F2802U (11,676 pcs) and AC1210FR-0728KL (3,108 pcs) also maintain substantial stock. RMCF1210FT28K0 (8,868 pcs) provides mid-range availability. All four parts are in active stock.
