RC3225J563CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225J563CS is a 56 kOhms ±5% 1/3W chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and is classified as Active product status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225J563CS is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 56 kOhms (exact match required)
• Package / Case: 1210 (3225 Metric) (mechanical compatibility)
• Composition: Thick Film (construction type)
• Temperature Coefficient: ±100ppm/°C (stability requirement)
• Operating Temperature Range: -55°C ~ 155°C (environmental compatibility)
• Moisture Resistance: Yes (feature requirement)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: MSL 1 (handling compatibility)

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±5% or better)
• Power Rating: May be equal or higher (0.333W or greater)

The RC1210FR-0756KL qualifies as a substitute part because it maintains all mandatory matching parameters while providing improved tolerance (±1% versus ±5%) and higher power rating (0.5W versus 0.333W).

Parameter Comparison

Engineering Selection Recommendations

RC3225J563CS (Samsung Electro-Mechanics) remains the primary component choice when:

• Original design specifications explicitly require Samsung Electro-Mechanics sourcing
• Supply chain continuity with the original manufacturer is prioritized
• The ±5% tolerance specification is sufficient for circuit requirements
• The 0.333W power rating is adequate for thermal design

RC1210FR-0756KL (YAGEO) is a qualified substitute when:

• Samsung Electro-Mechanics RC3225J563CS is unavailable or discontinued
• Circuit design can benefit from improved tolerance performance (±1% versus ±5%)
• Higher power dissipation capability (0.5W versus 0.333W) provides additional thermal margin
• YAGEO sourcing is acceptable within supply chain requirements
• Both components maintain identical RoHS3 compliance and MSL 1 handling requirements

Both parts are Active status products with current manufacturing availability. Substitution does not compromise regulatory compliance, environmental operating range, or mechanical package compatibility.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0756KL replace RC3225J563CS in any application?

A: RC1210FR-0756KL qualifies as a substitute when the circuit design permits tolerance improvement (±1% versus ±5%) and higher power rating (0.5W versus 0.333W). Both components share identical package dimensions within 1210 specification tolerance, identical operating temperature range, and identical compliance certifications. Substitution is valid from an electrical and mechanical standpoint.

Q: What are the dimensional differences between these parts?

A: RC3225J563CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with maximum seated height of 0.026" (0.66mm). RC1210FR-0756KL measures 0.122" L x 0.102" W (3.10mm x 2.60mm) with maximum seated height of 0.024" (0.60mm). Both fall within the 1210 (3225 Metric) package specification and are mechanically compatible with standard 1210 footprints.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). No compliance or certification differences exist between the two components.

Q: Why would I choose the substitute part over the original?

A: The RC1210FR-0756KL substitute offers tighter tolerance (±1% versus ±5%) for improved accuracy and higher power rating (0.5W versus 0.333W) for enhanced thermal margin. These characteristics may benefit circuits requiring higher precision or operating at elevated power levels within the 1210 package format.

Q: Can I use RC3225J563CS as a substitute for RC1210FR-0756KL?

A: No. Substitution is directional. RC3225J563CS has lower tolerance (±5% versus ±1%) and lower power rating (0.333W versus 0.5W). Using the original part in place of the higher-specification substitute would not meet the substitute's performance requirements.

Q: What is the packaging difference between these parts?

A: RC3225J563CS is supplied in standard packaging format. RC1210FR-0756KL is supplied in Tape & Reel (TR) format. Both are compatible with automated assembly processes. Packaging format does not affect electrical or mechanical compatibility.
