RC3225F9762CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F9762CS is a 97.6 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format with 0.333W power rating. This component is classified as Active product status and is currently in stock with 763 pieces available. The part is designed for general-purpose applications requiring moisture-resistant thick film construction with tight tolerance specifications.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit higher power ratings or alternative certifications such as automotive qualification. The ERJ-14NF9762U from Panasonic Electronic Components serves as a direct functional equivalent with enhanced power handling capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F9762CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 97.6 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Power Rating: May be equal to or greater than 0.333W
• Packaging Format: May differ (bulk, tape & reel, etc.)
• Product Status: May differ based on application requirements
• Certifications: May include additional qualifications (e.g., AEC-Q200)

The ERJ-14NF9762U qualifies as a substitute because it maintains all mandatory parameters while offering an increased power rating of 0.5W (1/2W), which provides additional design margin without compromising electrical or thermal performance in applications rated for 0.333W operation.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (RC3225F9762CS): The RC3225F9762CS is the preferred selection for new designs and applications where component availability and active product status are priorities. Active product status ensures long-term supply continuity and manufacturer support. This component is suitable for general industrial and consumer applications requiring standard thick film resistor performance.

Substitute Component (ERJ-14NF9762U): The ERJ-14NF9762U is applicable in the following scenarios:

1. Supply chain constraints affecting RC3225F9762CS availability
2. Applications where AEC-Q200 automotive qualification provides additional design assurance
3. Designs requiring higher power dissipation margin (0.5W vs. 0.333W)
4. Existing inventory of ERJ-14NF9762U available for immediate deployment

The "Not For New Designs" status of ERJ-14NF9762U indicates Panasonic's recommendation against incorporation into new product development; however, this does not preclude its use as a substitute in existing designs or where supply necessity dictates.

Both components maintain identical electrical performance characteristics (97.6 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and are mechanically compatible within standard PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q1: Can ERJ-14NF9762U be used as a direct replacement for RC3225F9762CS in existing designs?

A: Yes. The ERJ-14NF9762U maintains all critical electrical parameters (resistance value, tolerance, temperature coefficient, operating temperature range) and package dimensions (1210 / 3225 Metric). The increased power rating (0.5W vs. 0.333W) does not create compatibility issues in applications designed for 0.333W operation. Dimensional variations (width 2.50mm vs. 2.55mm, height 0.70mm vs. 0.66mm) are within standard PCB assembly tolerances.

Q2: What is the significance of the "Not For New Designs" status on ERJ-14NF9762U?

A: This designation indicates that Panasonic recommends against incorporating this part into new product development. However, it remains a valid substitute for existing designs, legacy product support, or temporary supply solutions. The part remains electrically and mechanically functional.

Q3: Does the higher power rating of ERJ-14NF9762U (0.5W vs. 0.333W) affect circuit performance?

A: No. A higher power rating does not alter electrical performance. The 97.6 kOhms resistance value, ±1% tolerance, and temperature coefficient remain identical. The increased power rating provides additional thermal margin and is fully backward-compatible with designs specified for 0.333W operation.

Q4: Are there packaging format differences between RC3225F9762CS and ERJ-14NF9762U?

A: Yes. RC3225F9762CS is supplied in standard packaging (not specified in detail), while ERJ-14NF9762U is supplied in Tape & Reel (TR) format. Both are compatible with standard SMD assembly equipment. Tape & Reel format may require different handling procedures during manufacturing.

Q5: What compliance certifications apply to both components?

A: Both RC3225F9762CS and ERJ-14NF9762U are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. ERJ-14NF9762U carries additional AEC-Q200 automotive qualification. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q6: Are dimensional differences between the two parts critical for PCB layout?

A: Dimensional differences are minimal and functionally compatible. RC3225F9762CS measures 3.20mm x 2.55mm x 0.66mm (max height), while ERJ-14NF9762U measures 3.20mm x 2.50mm x 0.70mm (max height). These variations fall within standard PCB footprint tolerances for 1210 package components and do not require layout modifications.
