RC3225F224CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F224CS is a 220 kOhms ±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 with full RoHS3 compliance and MSL Level 1 moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F224CS is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value: 220 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Mechanical Compatibility Requirements:

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

Regulatory & Environmental Requirements:

• RoHS3 Compliance (mandatory)
• MSL Level 1 or equivalent (mandatory)
• REACH Unaffected status (mandatory)

The RC1210FR-07220KL from YAGEO qualifies as a substitute part because it maintains all critical electrical parameters (220 kOhms, ±1% tolerance, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and mechanical compatibility (1210 package, 2 terminations, thick film composition). The power rating differential (0.5W versus 0.333W) represents an upgrade capability that does not restrict substitution in applications where the original 0.333W rating is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the RC3225F224CS and RC1210FR-07220KL maintain Active product status with full regulatory compliance across RoHS3, REACH, and MSL Level 1 certifications. Selection between these components should be based on the following engineering considerations:

RC3225F224CS (Samsung Electro-Mechanics): Select this part when the original design specification explicitly requires 0.333W power rating and Samsung sourcing is mandated by supply chain or qualification requirements.

RC1210FR-07220KL (YAGEO): Select this part when higher power dissipation capability (0.5W) is acceptable or beneficial for thermal margin, when YAGEO sourcing is preferred, or when supply availability of the Samsung part is constrained. The dimensional variance (0.122" L x 0.102" W versus 0.126" L x 0.100" W) and reduced seated height (0.024" versus 0.026") remain within standard 1210 package tolerances and do not restrict PCB layout compatibility.

Both parts are suitable for applications operating across the -55°C ~ 155°C temperature range with identical tolerance and temperature coefficient specifications.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-07220KL replace RC3225F224CS in all applications?

A: Yes, the RC1210FR-07220KL is electrically and mechanically compatible with RC3225F224CS. The higher power rating (0.5W versus 0.333W) does not restrict substitution and provides additional thermal margin. Dimensional differences remain within 1210 package specifications and do not affect PCB footprint compatibility.

Q: What are the critical parameters that must match for substitution?

A: Resistance value (220 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), package type (1210), composition (thick film), and regulatory compliance (RoHS3, MSL Level 1) must remain identical. Power rating may be equal or higher.

Q: Are there packaging differences between these parts?

A: RC3225F224CS is supplied in standard packaging, while RC1210FR-07220KL is supplied in Tape & Reel (TR) format. Both use identical 1210 (3225 Metric) component packages. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or compatibility.

Q: Do dimensional variations affect PCB layout?

A: Dimensional variations (0.126" L x 0.100" W for Samsung versus 0.122" L x 0.102" W for YAGEO) are within standard 1210 package tolerances. Seated height difference (0.026" versus 0.024") does not restrict placement on standard PCB designs. Both components are footprint-compatible with 1210 land patterns.

Q: Are both parts RoHS3 compliant?

A: Yes, both RC3225F224CS and RC1210FR-07220KL are ROHS3 Compliant with MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: What is the difference in power rating between these parts?

A: RC3225F224CS is rated at 0.333W (1/3W), while RC1210FR-07220KL is rated at 0.5W (1/2W). The higher power rating of the YAGEO part provides additional thermal dissipation capability without affecting electrical performance in applications designed for the lower rating.
