Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F5230CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 523 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 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)
• RoHS Status: ROHS3 Compliant (minimum requirement)

Allowable Variation Parameters:

• Power Rating: Substitute parts may exceed the 0.333W specification, provided the higher power rating does not introduce incompatibility with circuit design constraints
• Physical Dimensions: Minor variations within the 1210 package specification are acceptable
• Packaging Format: Substitutes may differ in packaging (Tape & Reel vs. bulk) without affecting electrical performance

The AC1210FR-07523RL from YAGEO qualifies as a direct substitute based on matching all mandatory parameters while providing an enhanced power rating of 0.5W (1/2W) and automotive-grade AEC-Q200 certification.

Engineering Selection Recommendations

Primary Part: RC3225F5230CS

The RC3225F5230CS remains the specified component for applications where the 0.333W power rating is the design requirement and Samsung Electro-Mechanics sourcing is mandated. This part is Active in production status with adequate inventory availability (992 units in stock).

Substitute Part: AC1210FR-07523RL

The AC1210FR-07523RL from YAGEO is a qualified substitute for the RC3225F5230CS. This substitution is valid based on the following engineering criteria:

• All electrical parameters (resistance, tolerance, temperature coefficient) are identical
• Package and mechanical dimensions are compatible within 1210 specification tolerances
• Operating temperature range is equivalent
• Environmental compliance (RoHS3, REACH Unaffected, MSL 1) is maintained
• Both parts are Active in production status
• The substitute provides enhanced power rating (0.5W vs. 0.333W), which does not create incompatibility in circuits designed for the lower rating
• The substitute includes automotive-grade AEC-Q200 certification, providing additional quality assurance for demanding applications

Substitution is appropriate for procurement continuity, inventory optimization, and applications where automotive-grade reliability is beneficial. Physical dimensions remain within acceptable PCB layout tolerances.

Frequently Asked Questions (FAQ)

Q: Can the AC1210FR-07523RL replace the RC3225F5230CS in all applications?

A: Yes, the AC1210FR-07523RL is a direct electrical and mechanical substitute. Both parts share identical resistance values (523 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package format (1210). The substitute's higher power rating (0.5W vs. 0.333W) does not create incompatibility in circuits designed for the original 0.333W specification.

Q: What are the physical dimension differences between these parts?

A: The RC3225F5230CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with a maximum seated height of 0.026" (0.66mm). The AC1210FR-07523RL measures 0.122" L x 0.102" W (3.10mm x 2.60mm) with a maximum seated height of 0.024" (0.60mm). Both dimensions fall within the 1210 package specification tolerance and are compatible with standard PCB layouts designed for 1210 components.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 Compliant and REACH Unaffected. Both maintain Moisture Sensitivity Level 1 (Unlimited). The AC1210FR-07523RL includes additional automotive-grade AEC-Q200 certification, which provides enhanced quality assurance but does not restrict its use in non-automotive applications.

Q: What is the difference in packaging between these parts?

A: The RC3225F5230CS is supplied in standard packaging format. The AC1210FR-07523RL is supplied in Tape & Reel (TR) format. Both packaging formats contain identical components; the difference is in the delivery and handling method. Tape & Reel format is standard for automated assembly processes.

Q: Can I use the substitute if my design specifies the Samsung part number?

A: Substitution is an engineering decision based on electrical and mechanical compatibility. The AC1210FR-07523RL meets all electrical and mechanical requirements of the RC3225F5230CS. Design specifications should be reviewed to confirm that manufacturer-specific requirements do not apply. If the design permits cross-manufacturer substitution based on electrical and mechanical parameters, the YAGEO part is qualified.

Q: What is the inventory status of each part?

A: The RC3225F5230CS has 992 units in stock. The AC1210FR-07523RL has 10,817 units in stock, providing significantly greater availability for procurement planning.
