RC3225F8250CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F8250CS is a 825 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 687 units currently in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowable parameter tolerances for this resistor category. Alternative sources may be required due to supply chain considerations, inventory availability, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F8250CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 825 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings (0.5W or greater is acceptable as it provides equivalent or superior capability)
• Physical dimensions: Minor variations within package specification tolerances are acceptable
• Packaging format: Both Tape & Reel and bulk packaging formats are compatible for component-level substitution

The identified substitute parts CRCW1210825RFKEA and ERJ-14NF8250U meet all mandatory parameters while providing higher power ratings (0.5W), which represents a compatible upgrade path for this application.

Parameter Comparison

Engineering Selection Recommendations

CRCW1210825RFKEA (Vishay Dale) is the primary substitute option. This part maintains Active product status, carries AEC-Q200 automotive qualification, and provides 0.5W power rating capability. All electrical and mechanical parameters align with the RC3225F8250CS specification. The higher power rating offers design margin without introducing incompatibility. ROHS3 compliance and MSL 1 rating ensure environmental and moisture handling equivalence.

ERJ-14NF8250U (Panasonic Electronic Components) is a secondary substitute option. While this part meets all electrical and mechanical requirements with identical resistance, tolerance, and temperature characteristics, it carries a "Not For New Designs" product status designation. This part is suitable for replacement or repair applications in existing designs but should not be selected for new product development. AEC-Q200 automotive qualification is present. The 0.5W power rating and ROHS3 compliance are equivalent to the primary substitute.

For new design implementations, CRCW1210825RFKEA is the recommended selection. For legacy system maintenance or repair scenarios where the original RC3225F8250CS is unavailable, ERJ-14NF8250U provides functional equivalence with the noted product status limitation.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210825RFKEA directly replace RC3225F8250CS in existing designs?

A: Yes. Both parts share identical resistance (825 Ohms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The CRCW1210825RFKEA provides higher power rating (0.5W versus 0.333W), which is compatible with the original design requirements.

Q: What is the significance of the higher power rating in CRCW1210825RFKEA?

A: The 0.5W rating in CRCW1210825RFKEA exceeds the 0.333W requirement of RC3225F8250CS. This represents a capability upgrade that does not introduce incompatibility. The component can safely handle the same or lower power dissipation as the original part.

Q: Why is ERJ-14NF8250U marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued this part for new product development. While the part remains functionally equivalent and suitable for replacement in existing systems, it should not be selected for new designs where alternative active parts are available.

Q: Are there packaging format differences between these substitutes?

A: RC3225F8250CS is supplied in standard packaging format. CRCW1210825RFKEA and ERJ-14NF8250U are supplied in Tape & Reel (TR) format. Both formats contain identical components; the difference is in the delivery and handling method. Component-level substitution is compatible regardless of packaging format.

Q: Do all three parts meet the same compliance standards?

A: Yes. RC3225F8250CS, CRCW1210825RFKEA, and ERJ-14NF8250U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. CRCW1210825RFKEA and ERJ-14NF8250U additionally carry AEC-Q200 automotive qualification, which is not specified for the Samsung part.

Q: What is the physical dimension difference between these parts?

A: All three parts conform to the 1210 (3225 Metric) package specification. Minor dimensional variations exist within tolerance: RC3225F8250CS measures 0.126" L x 0.100" W with 0.026" max height; CRCW1210825RFKEA measures 0.126" L x 0.098" W with 0.024" max height; ERJ-14NF8250U measures 0.126" L x 0.098" W with 0.028" max height. These variations remain within standard 1210 package tolerances and do not affect PCB layout compatibility.
