RC3225F273CS Equivalent & Substitute Parts

Part Overview

The RC3225F273CS is a 27 kOhm ±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 and operates across the temperature range of -55°C to 155°C. The part is currently in Active product status and features moisture-resistant construction with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit the use of alternative manufacturers' components that meet or exceed the electrical and mechanical specifications of the original part.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3225F273CS is permissible when the alternative component maintains the following critical parameters:

• Resistance Value: 27 kOhms (exact match required)
• Tolerance: ±1% (equal or tighter tolerance acceptable)
• Package Format: 1210 (3225 Metric) (identical package required for PCB compatibility)
• Composition: Thick Film (maintains electrical characteristics)
• Temperature Coefficient: ±100ppm/°C (equal or better stability acceptable)
• Operating Temperature Range: -55°C to 155°C (minimum requirement)
• Number of Terminations: 2 (standard configuration)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The power rating of the substitute component may exceed the original specification (0.333W minimum), as higher power ratings provide additional design margin without affecting circuit performance. The ERJ-14NF2702U meets all substitution criteria with a 0.5W (1/2W) power rating, providing enhanced thermal capability within the identical 1210 package footprint.

Parameter Comparison

Engineering Selection Recommendations

The RC3225F273CS remains the primary component choice for new designs due to its Active product status. The Samsung Electro-Mechanics RC series offers long-term availability and supply stability for production applications.

The ERJ-14NF2702U from Panasonic Electronic Components serves as a functional equivalent for existing designs or applications where supply of the primary part is constrained. This substitute maintains electrical equivalence through identical resistance, tolerance, temperature coefficient, and operating temperature specifications. The increased power rating (0.5W versus 0.333W) provides additional thermal margin without introducing compatibility issues in standard circuit applications.

The ERJ-14NF2702U carries "Not For New Designs" status, indicating that Panasonic has transitioned this component to mature product lifecycle phase. For new design implementations, the RC3225F273CS is the recommended selection. For legacy system support or supply contingency, the ERJ-14NF2702U remains electrically and mechanically compatible.

Both components maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage environments.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF2702U be used as a direct replacement for the RC3225F273CS in existing assemblies?

A: Yes. The ERJ-14NF2702U is electrically and mechanically compatible with the RC3225F273CS. Both components share identical resistance (27 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and 1210 package format. The substitute's higher power rating (0.5W versus 0.333W) does not create compatibility issues.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF2702U?

A: This designation indicates that Panasonic has classified the ERJ-14NF2702U as a mature product and is not actively promoting it for new circuit designs. However, the component remains available for production and is suitable for replacement applications or supply contingency scenarios. For new designs, the RC3225F273CS is the recommended primary selection.

Q: Are there dimensional differences between these components that affect PCB layout?

A: Both components use the 1210 (3225 Metric) package format with identical length (0.126" / 3.20mm). The width differs slightly (RC3225F273CS: 0.100" / 2.55mm versus ERJ-14NF2702U: 0.098" / 2.50mm), and the seated height differs marginally (RC3225F273CS: 0.026" / 0.66mm versus ERJ-14NF2702U: 0.028" / 0.70mm). These dimensional variations are within standard PCB design tolerances and do not require layout modifications.

Q: Do both components meet the same regulatory and compliance requirements?

A: Yes. Both the RC3225F273CS and ERJ-14NF2702U are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both components carry unlimited moisture sensitivity level (MSL 1), indicating no special storage or handling requirements beyond standard manufacturing practices.

Q: What determines whether a component qualifies as a substitute for the RC3225F273CS?

A: Substitution eligibility is determined by matching or exceeding the following parameters: 27 kOhm resistance value, ±1% tolerance, 1210 package format, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating temperature range, and ROHS3 compliance. Power rating may exceed the original specification. All other electrical and mechanical characteristics must remain within specified tolerances.
