Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F560CS are qualified based on the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Resistance value: 56 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Resistance: Required
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitutes may have equal or higher power dissipation (0.5W or greater is acceptable as an upgrade)
• Manufacturer: Different manufacturers permitted
• Series designation: May differ
• Packaging format: Tape & Reel acceptable as alternative to standard packaging

The identified substitutes AC1210FR-0756RL and RC1210FR-0756RL meet all mandatory parameters and provide upgraded power ratings of 0.5W (1/2W), representing a performance enhancement over the original 0.333W specification.

Parameter Comparison

Engineering Selection Recommendations

RC3225F560CS (Original Part): Select this part when the original Samsung Electro-Mechanics specification is required by design documentation or when supply from the original manufacturer is mandated by procurement requirements.

AC1210FR-0756RL (YAGEO - Automotive Grade): This substitute provides an upgrade path with 0.5W power rating and AEC-Q200 automotive qualification. Select this part when automotive-grade reliability is required or when the application benefits from increased power dissipation margin. The automotive qualification adds an additional compliance layer suitable for automotive and industrial environments.

RC1210FR-0756RL (YAGEO - Standard Grade): This substitute provides an upgrade path with 0.5W power rating without automotive qualification. Select this part when increased power dissipation margin is beneficial and automotive qualification is not a requirement. This option offers cost efficiency while maintaining all core electrical and environmental specifications.

All three parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical performance in terms of resistance, tolerance, and temperature coefficient. The primary differentiators are manufacturer identity, power rating upgrade, and automotive qualification status.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-0756RL or RC1210FR-0756RL be used as direct replacements for RC3225F560CS?

A: Yes. Both substitute parts match all mandatory electrical parameters (56 Ohms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical specifications (1210 package, thick film composition, moisture resistance, ROHS3 compliance, MSL 1). The 0.5W power rating represents an upgrade from the original 0.333W specification.

Q: What is the difference between AC1210FR-0756RL and RC1210FR-0756RL?

A: Both parts are manufactured by YAGEO and share identical electrical specifications and 0.5W power rating. The primary difference is that AC1210FR-0756RL carries AEC-Q200 automotive qualification, while RC1210FR-0756RL does not. Select AC1210FR-0756RL for automotive applications; select RC1210FR-0756RL for general industrial and consumer applications.

Q: Are there any physical dimension differences between the main part and substitutes?

A: Minor dimensional variations exist within the 1210 package specification. RC3225F560CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" maximum seated height. Both YAGEO substitutes measure 0.122" L x 0.102" W (3.10mm x 2.60mm) with 0.024" maximum seated height. These variations remain within standard 1210 package tolerances and do not affect PCB footprint compatibility.

Q: Does the power rating upgrade affect circuit performance?

A: The upgrade from 0.333W to 0.5W increases the component's thermal dissipation capability without altering electrical performance. Resistance value, tolerance, and temperature coefficient remain identical. The higher power rating provides additional safety margin in applications where thermal stress is a consideration.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC3225F560CS, AC1210FR-0756RL, and RC1210FR-0756RL are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: For new designs without automotive requirements, RC1210FR-0756RL offers equivalent performance with upgraded power rating and strong supply availability. For automotive applications, AC1210FR-0756RL provides the same benefits with AEC-Q200 qualification. Both represent forward-compatible selections with supply chain flexibility.
