Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225J823CS are identified based on the following critical parameters that determine functional and physical compatibility:

Mandatory Matching Parameters:

• Resistance Value: 82 kOhms (exact match required)
• Package / Case: 1210 (3225 Metric) (physical footprint compatibility)
• Composition: Thick Film (material consistency)
• Temperature Coefficient: ±100ppm/°C (thermal stability)
• Operating Temperature Range: -55°C to 155°C (environmental compatibility)
• Moisture Resistance: Present (environmental protection)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

Allowable Parameter Variations:

• Tolerance: May be equal or tighter (±5% or better)
• Power Rating: May be equal or higher (0.333W or greater)
• Physical Dimensions: Minor variations within package class tolerance
• MSL Rating: Equal or superior protection level

The RC1210FR-0782KL from YAGEO qualifies as a substitute part because it maintains all mandatory parameters while offering improved tolerance (±1% versus ±5%) and increased power rating (0.5W versus 0.333W), providing enhanced performance margins within the identical package footprint.

Parameter Comparison

Engineering Selection Recommendations

The RC1210FR-0782KL from YAGEO is a direct substitute for the RC3225J823CS from Samsung Electro-Mechanics. Both components maintain identical electrical specifications for resistance value, temperature coefficient, and operating temperature range. Both are ROHS3 compliant with MSL Level 1 ratings, ensuring equivalent regulatory and environmental protection standards.

The YAGEO substitute offers performance enhancements through tighter tolerance (±1% versus ±5%) and increased power dissipation capability (0.5W versus 0.333W), providing additional design margin without compromising compatibility. Physical dimensions remain within the 1210 package class specification, ensuring PCB footprint compatibility and assembly process compatibility.

Selection between these parts should be based on design requirements for tolerance precision and power margin, availability, and supply chain considerations. Both parts are Active status components suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Can the RC1210FR-0782KL replace the RC3225J823CS in existing designs?

A: Yes. The RC1210FR-0782KL is a direct substitute with identical resistance value, package footprint, and operating temperature range. Physical dimensions fall within 1210 package tolerance, ensuring PCB compatibility without layout modifications.

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

A: The primary differences are tolerance grade (±1% versus ±5%) and power rating (0.5W versus 0.333W). The YAGEO substitute provides tighter tolerance and higher power dissipation capability, both representing performance improvements over the original Samsung part.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RC3225J823CS and RC1210FR-0782KL are ROHS3 compliant with MSL Level 1 ratings, meeting identical regulatory and environmental protection requirements.

Q: Does the tighter tolerance of the substitute part affect circuit performance?

A: Tighter tolerance (±1%) provides improved accuracy compared to the original ±5% specification. This represents an enhancement that does not negatively impact circuit performance and may improve precision in applications requiring tighter resistance values.

Q: Are there packaging differences between these parts?

A: The RC3225J823CS is supplied in standard packaging, while the RC1210FR-0782KL is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes. Verify packaging requirements for your procurement and assembly workflow.

Q: What is the temperature coefficient significance for these parts?

A: Both parts share identical temperature coefficient of ±100ppm/°C, ensuring equivalent thermal stability across the -55°C to 155°C operating range. This parameter does not differentiate the parts and does not affect substitution compatibility.

Q: Can the higher power rating of the substitute cause issues?

A: No. Higher power rating (0.5W versus 0.333W) provides additional thermal margin and does not create compatibility issues. The component will operate safely at or below the original design power dissipation level.
