Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F563CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 56 kOhms
• Tolerance: ±1%
• Package / Case: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Resistant feature
• RoHS3 Compliance
• MSL Level 1 rating

Allowable Variation:

• Power rating may be equal or higher than 0.333W (1/3W), provided the package dimensions remain within 1210 specifications
• Physical dimensions may vary within standard 1210 tolerances
• Packaging format (bulk, tape & reel) does not affect electrical substitution eligibility

The RC1210FR-0756KL from YAGEO qualifies as a substitute because it maintains all mandatory electrical parameters while providing increased power rating (0.5W / 1/2W) within the same 1210 package envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC3225F563CS): Select the Samsung Electro-Mechanics RC3225F563CS when the original specification calls for 0.333W (1/3W) power dissipation and Samsung components are preferred for supply chain or qualification requirements. Active product status ensures continued availability and manufacturing support.

Substitute Selection (RC1210FR-0756KL): The YAGEO RC1210FR-0756KL is suitable for applications where the RC3225F563CS is unavailable or when higher power margin is beneficial. The 0.5W (1/2W) rating provides additional thermal headroom without altering circuit performance. Both components maintain identical electrical characteristics (56 kOhms ±1%, ±100ppm/°C) and environmental compliance (RoHS3, MSL Level 1, REACH Unaffected). Physical dimensions remain within 1210 package specifications, ensuring PCB layout compatibility.

Both parts are Active status with full compliance documentation available.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0756KL replace RC3225F563CS in any application?

A: Yes, within the constraints of PCB layout and thermal design. The substitute part maintains identical resistance value (56 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The higher power rating (0.5W vs. 0.333W) does not create incompatibility; it provides additional thermal margin. Verify that PCB footprint accommodates the 1210 package dimensions of both parts.

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

A: RC3225F563CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" (0.66mm) maximum seated height. RC1210FR-0756KL measures 0.122" L x 0.102" W (3.10mm x 2.60mm) with 0.024" (0.60mm) maximum seated height. Both fall within standard 1210 (3225 Metric) package tolerances and are mechanically interchangeable on standard 1210 footprints.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC3225F563CS and RC1210FR-0756KL carry ROHS3 Compliant certification and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these resistors?

A: Both parts are rated MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or baking requirements.

Q: Can these parts be used interchangeably in tape & reel or bulk packaging?

A: Packaging format (tape & reel or bulk) does not affect electrical or mechanical substitution. The RC1210FR-0756KL is supplied in Tape & Reel format, while the RC3225F563CS may be available in alternative packaging. Select based on assembly process requirements; electrical performance is independent of packaging format.

Q: What is the temperature coefficient specification and why does it matter?

A: Both parts specify ±100ppm/°C temperature coefficient, meaning resistance value changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. This specification is identical between parts and ensures predictable circuit behavior across the -55°C ~ 155°C operating range.
