RC3225F16R5CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F16R5CS is a 16.5 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) power dissipation in a 1210 (3225 Metric) package. This component is classified as Active product status and is currently in stock with 891 pieces available.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package form factor. The primary substitute listed is the ERJ-14NF16R5U from Panasonic Electronic Components, which shares identical resistance value, tolerance, and package dimensions while offering increased power rating and automotive qualification.

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F16R5CS is determined by strict adherence to the following criteria:

Critical Matching Parameters:

• Resistance value: 16.5 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package form factor: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

Allowable Variation Parameters:

• Power Rating: May be equal to or greater than 0.333W
• Supplier Device Package: Equivalent 1210 package designation
• Physical dimensions: Within tolerance of specified 1210 package
• Compliance certifications: May include additional qualifications (e.g., AEC-Q200)

The ERJ-14NF16R5U qualifies as a substitute because it maintains all critical matching parameters while offering a higher power rating (0.5W versus 0.333W) and automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (RC3225F16R5CS): The RC3225F16R5CS is recommended for new designs requiring a 16.5 Ohm 1% tolerance thick film resistor in 1210 package format. This part maintains Active product status and is available in quantity (891 pieces in stock). It satisfies ROHS3 compliance and REACH unaffected requirements for standard industrial and commercial applications.

Substitute Part Selection (ERJ-14NF16R5U): The ERJ-14NF16R5U is available as a substitute when higher power dissipation capability (0.5W versus 0.333W) is required within the same package footprint. This part carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. However, this part is designated "Not For New Designs," indicating it should be used only when existing design compatibility or supply continuity requires it.

Compliance Considerations: Both parts maintain ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application power requirements and whether automotive qualification is necessary for the end application.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF16R5U directly replace the RC3225F16R5CS in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical resistance (16.5 Ohms), tolerance (±1%), package (1210), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The ERJ-14NF16R5U provides higher power rating (0.5W versus 0.333W), which is compatible with applications designed for the lower-rated part. However, the ERJ-14NF16R5U is marked "Not For New Designs," so substitution should be evaluated against design requirements and supply constraints.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Manufacturer—Samsung Electro-Mechanics versus Panasonic Electronic Components; (2) Power rating—0.333W versus 0.5W; (3) Automotive qualification—ERJ-14NF16R5U includes AEC-Q200 certification; (4) Product status—RC3225F16R5CS is Active while ERJ-14NF16R5U is Not For New Designs; (5) Packaging—RC3225F16R5CS supplied as loose components, ERJ-14NF16R5U supplied in Tape & Reel format.

Q: Are the physical dimensions identical?

A: Dimensions are equivalent within 1210 package specification. RC3225F16R5CS specifies 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" max height. ERJ-14NF16R5U specifies 0.126" L x 0.098" W (3.20mm x 2.50mm) with 0.028" max height. These minor variations remain within 1210 package tolerance and do not affect PCB footprint compatibility.

Q: Can I use the ERJ-14NF16R5U in a circuit designed for 0.333W power dissipation?

A: Yes. The ERJ-14NF16R5U's 0.5W rating exceeds the 0.333W requirement, providing additional thermal margin. This substitution is electrically and mechanically valid.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The ERJ-14NF16R5U additionally carries AEC-Q200 automotive qualification, which is not specified for the RC3225F16R5CS.

Q: Why is the ERJ-14NF16R5U marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. It remains available for existing design support and replacement purposes but should not be selected for new product development. The RC3225F16R5CS, with Active status, is the preferred choice for new designs.
