RC3225F25R5CS Equivalent & Substitute Parts

Part Overview

The RC3225F25R5CS is a 25.5 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.333W (1/3W) power dissipation in a 1210 (3225 Metric) surface mount package. This component is classified as Active product status with moisture resistant characteristics and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications (resistance value, tolerance, power rating, temperature coefficient, and operating temperature range) and mechanical compatibility (package type, termination count, and physical dimensions) align with the main part's functional requirements. The RC3225F25R5CS may require substitution due to inventory constraints, supply chain availability, or specific application certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F25R5CS is determined by strict alignment of the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 25.5 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility Requirements:

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

Regulatory & Environmental Requirements:

• RoHS3 Compliance (required)
• Moisture Sensitivity Level 1 or equivalent (required)

Power Rating Consideration: The main part is rated at 0.333W (1/3W). Substitute parts with equal or higher power ratings (0.5W or greater) are electrically compatible, as they can safely dissipate the same or lower power levels without exceeding thermal limits.

Engineering Selection Recommendations

RC3225F25R5CS (Main Part - Recommended for New Designs): The RC3225F25R5CS maintains Active product status, indicating ongoing manufacturer support and availability. This part is suitable for all new design implementations and applications requiring long-term supply chain stability.

ERJ-14NF25R5U (Substitute - Limited to Existing Designs): The ERJ-14NF25R5U is classified as "Not For New Designs" by Panasonic Electronic Components. This designation indicates the part is available for replacement and maintenance of existing applications but should not be selected for new product development. The substitute carries AEC-Q200 automotive qualification, which provides additional reliability assurance for automotive applications. The higher power rating (0.5W vs. 0.333W) ensures thermal margin compatibility. Physical dimensions are within acceptable tolerance for 1210 package footprints.

Selection Criteria:

• For new designs: Use RC3225F25R5CS
• For existing design maintenance or automotive applications: ERJ-14NF25R5U is electrically and mechanically compatible
• Both parts meet ROHS3 compliance and REACH requirements
• Both parts operate across the full -55°C ~ 155°C temperature range with identical temperature coefficients

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF25R5U replace RC3225F25R5CS in existing applications?

A: Yes. The ERJ-14NF25R5U is electrically equivalent (25.5 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C) and mechanically compatible (1210 package, 2 terminations, thick film composition). The higher power rating (0.5W vs. 0.333W) provides additional thermal margin. Physical dimensions are within acceptable tolerance for standard 1210 footprints.

Q: Why is ERJ-14NF25R5U marked "Not For New Designs"?

A: This designation reflects Panasonic's product lifecycle management. The part remains available for replacement and maintenance of existing designs but is not recommended for new product development. For new designs, RC3225F25R5CS (Active status) is the appropriate selection.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the 1210 package specification. RC3225F25R5CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" max height. ERJ-14NF25R5U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with 0.028" max height. Both fall within standard 1210 package tolerances and are compatible with standard PCB footprints.

Q: Do both parts meet automotive standards?

A: RC3225F25R5CS meets general industrial standards (ROHS3, REACH). ERJ-14NF25R5U carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring this certification.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply without special drying or storage requirements.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, from electrical and mechanical perspectives. Both parts are 1210 package, 2-termination thick film resistors with identical electrical specifications. Standard PCB assembly processes apply to both parts.
