RC3225F182CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F182CS is a 1.8 kOhms ±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 and is ROHS3 compliant with MSL Level 1 rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint, tolerance class, and environmental operating parameters.

Substitute Part Grouping Explanation

Substitute parts for the RC3225F182CS are qualified based on the following criteria:

Electrical Equivalence:

• Identical resistance value: 1.8 kOhms
• Matching tolerance class: ±1%
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C to 155°C

Mechanical Compatibility:

• Same package footprint: 1210 (3225 Metric)
• Compatible physical dimensions within supplier device package specifications
• Two terminations (standard for chip resistors)

Environmental & Compliance:

• Moisture-resistant thick film construction
• ROHS3 compliance
• MSL Level 1 rating
• REACH unaffected status

Acceptable Variations:

• Power rating may be equal or higher (0.333W or greater)
• Manufacturer may differ
• Packaging format may differ (bulk vs. Tape & Reel)
• Additional certifications (such as AEC-Q200) do not disqualify substitution

Parameter Comparison

Engineering Selection Recommendations

RC1210FR-071K8L (YAGEO): This part is a direct functional substitute with identical electrical parameters and higher power rating (0.5W vs. 0.333W). Both parts maintain Active product status, ROHS3 compliance, and MSL Level 1 rating. The increased power dissipation capability provides design margin without affecting circuit performance in applications rated for the original 0.333W specification.

AC1210FR-071K8L (YAGEO): This part meets all electrical and mechanical substitution criteria and includes AEC-Q200 automotive qualification. Selection of this variant is appropriate for applications requiring automotive-grade component certification while maintaining identical electrical performance and package compatibility.

Both substitute parts are suitable for direct replacement based on provided specifications and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-071K8L and AC1210FR-071K8L be used interchangeably with RC3225F182CS?

A: Yes. Both parts maintain identical resistance value (1.8 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and package footprint (1210/3225 Metric). The higher power ratings (0.5W) are compatible with applications designed for 0.333W components.

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

A: The substitute parts are rated for 0.5W (1/2W) compared to the original 0.333W (1/3W). This represents increased thermal capability and does not affect electrical performance in circuits designed for the lower rating. The component will operate within specification in all applications where the original part was used.

Q: Does the AEC-Q200 certification on AC1210FR-071K8L affect its use in non-automotive applications?

A: No. AEC-Q200 is an additional qualification that does not restrict use in non-automotive applications. The part meets all base specifications and compliance requirements for general industrial use.

Q: Are there packaging differences between the substitute parts?

A: RC3225F182CS is supplied in standard packaging format. RC1210FR-071K8L and AC1210FR-071K8L are supplied in Tape & Reel (TR) format. Both packaging types contain identical components; the difference is in delivery and handling format only.

Q: Do all three parts have identical physical dimensions?

A: The parts have compatible dimensions within the 1210 (3225 Metric) package specification. Specific measurements are: RC3225F182CS (3.20mm L x 2.55mm W x 0.66mm H max), RC1210FR-071K8L and AC1210FR-071K8L (3.10mm L x 2.60mm W x 0.60mm H max). These variations are within standard package tolerance and do not affect PCB layout compatibility.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and rated MSL Level 1 (Unlimited moisture sensitivity level). ECCN classification is EAR99 for all parts.
