RC3225F5762CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F5762CS is a 57.6 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) power dissipation in a 1210 (3225 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. The primary substitute ERJ-14NF5762U from Panasonic Electronic Components carries identical resistance and tolerance values with higher power rating capability, though it carries a Not For New Designs status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F5762CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 57.6 kOhms
• Tolerance: ±1%
• Package footprint: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance status

Allowable Variation Parameters:

• Power rating: Substitute parts may exceed the 0.333W specification, provided the package dimensions remain compatible with 1210 footprint constraints
• Product status: Active or Not For New Designs classifications do not disqualify electrical equivalence
• Packaging format: Original packaging (Tape & Reel vs. bulk) does not affect functional substitution

The identified substitute ERJ-14NF5762U meets all mandatory parameters with a higher power rating of 0.5W (1/2W), maintaining identical electrical performance within the specified operating envelope.

Engineering Selection Recommendations

For Active Product Designs: The RC3225F5762CS maintains Active product status with full manufacturing support and long-term availability assurance. This component is the primary selection for new circuit designs requiring 57.6 kOhms ±1% 1/3W 1210 resistors with Samsung Electro-Mechanics sourcing.

For Substitute Selection: The ERJ-14NF5762U from Panasonic Electronic Components provides electrical equivalence with identical resistance, tolerance, temperature coefficient, and operating range. The higher 0.5W power rating offers additional thermal margin in applications where the original 0.333W specification is marginal. However, the Not For New Designs status indicates Panasonic has discontinued active development for this part number. Substitution is appropriate for legacy system maintenance, repair operations, or applications where existing inventory must be supplemented.

Compliance Considerations: Both components maintain ROHS3 compliance, MSL 1 rating, and identical environmental operating specifications. Dimensional variations between the two parts (width 0.100" vs. 0.098", height 0.026" vs. 0.028") are within standard PCB layout tolerances for 1210 footprint designs and do not require circuit board redesign.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF5762U replace RC3225F5762CS in existing designs?

A: Yes. The ERJ-14NF5762U provides electrical equivalence with identical 57.6 kOhms ±1% resistance, tolerance, temperature coefficient, and operating temperature range. The higher 0.5W power rating is compatible with 1210 package constraints. Dimensional variations are negligible for standard PCB layouts.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF5762U?

A: This classification indicates Panasonic has transitioned this part number away from active development and new product qualification. It remains available for existing applications and repair operations but should not be selected for new circuit designs where long-term supply continuity is required. The RC3225F5762CS Active status provides superior supply assurance for new designs.

Q: Are there dimensional compatibility concerns between these two parts?

A: Dimensional differences are minimal. The RC3225F5762CS measures 0.126" L x 0.100" W x 0.026" H (max), while the ERJ-14NF5762U measures 0.126" L x 0.098" W x 0.028" H (max). These variations fall within standard 1210 package tolerances and do not require PCB footprint modification.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both components are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain identical operating temperature specifications (-55°C ~ 155°C). Compliance profiles are equivalent for regulatory and environmental applications.

Q: Why does the ERJ-14NF5762U have a higher power rating?

A: The 0.5W (1/2W) rating on the ERJ-14NF5762U versus 0.333W (1/3W) on the RC3225F5762CS reflects different thermal design approaches within the same 1210 package footprint. Higher power rating provides additional thermal dissipation capability without affecting electrical performance or package dimensions.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Electrical substitution is valid. However, the Active status of RC3225F5762CS provides superior traceability, manufacturing consistency, and long-term availability for high-reliability requirements. The ERJ-14NF5762U Not For New Designs status may present supply chain constraints for critical applications requiring extended production runs.
