RC3225F4753CS Equivalent & Substitute Parts

Part Overview

The RC3225F4753CS is a 475 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 with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary manufacturer experiences supply constraints, when design requirements shift toward automotive-qualified components, or when higher power ratings are required within the same package footprint while maintaining electrical equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3225F4753CS is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Resistance value: 475 kOhms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS3 compliance

Allowable Variation:

• Power rating may exceed the original specification (0.333W minimum required)
• Packaging format (bulk vs. tape & reel) does not affect electrical equivalence
• Product status differences are noted for design lifecycle considerations

The ERJ-14NF4753U from Panasonic Electronic Components satisfies all mandatory equivalence criteria while providing an elevated power rating of 0.5W (1/2W) within the identical 1210 package footprint.

Engineering Selection Recommendations

RC3225F4753CS Selection Criteria:

• Primary choice for new designs requiring active product status
• Suitable for applications where 0.333W power dissipation is sufficient
• Recommended when Samsung Electro-Mechanics supply chain is preferred or established

ERJ-14NF4753U Selection Criteria:

• Electrical equivalent with higher power rating margin (0.5W vs. 0.333W)
• Includes AEC-Q200 automotive qualification for applications requiring automotive-grade components
• Appropriate for designs where additional thermal headroom is beneficial
• Note: Product status is "Not For New Designs"; use only when supply of RC3225F4753CS is unavailable or when automotive qualification is mandatory

Both parts maintain identical electrical performance in resistance value, tolerance, temperature coefficient, and operating temperature range. The choice between them depends on supply availability, automotive qualification requirements, and design lifecycle phase.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF4753U directly replace RC3225F4753CS in existing designs?

A: Yes. Both components share identical resistance value (475 kOhms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The ERJ-14NF4753U provides higher power rating (0.5W vs. 0.333W), which is compatible with applications designed for the lower-rated part.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF4753U?

A: This designation indicates that Panasonic has classified this part as obsolescent for new product development. While the component remains electrically and mechanically equivalent, it should be used only when RC3225F4753CS supply is constrained or when existing designs require continuation. New designs should prioritize the RC3225F4753CS or evaluate alternative suppliers.

Q: Are there dimensional differences between these parts?

A: Dimensions are nearly identical. RC3225F4753CS measures 0.126" L × 0.100" W (3.20mm × 2.55mm) with maximum seated height of 0.026" (0.66mm). ERJ-14NF4753U measures 0.126" L × 0.098" W (3.20mm × 2.50mm) with maximum seated height of 0.028" (0.70mm). These minor variations do not affect PCB layout or assembly compatibility.

Q: Does ERJ-14NF4753U require different handling or storage procedures?

A: No. Both parts share identical Moisture Sensitivity Level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling. Both are RoHS3 compliant and REACH unaffected.

Q: When should AEC-Q200 qualification be a selection factor?

A: AEC-Q200 qualification on ERJ-14NF4753U is relevant only for automotive applications or designs requiring automotive-grade component traceability. For general industrial, consumer, or commercial applications, this qualification is not a functional requirement.
