RC3225F1620CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F1620CS is a 162 Ohm ±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 are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this resistor category. Substitution becomes necessary due to inventory availability, supply chain optimization, or design flexibility requirements while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC3225F1620CS is based on the following criteria:

Electrical Parameter Matching:

• Resistance value must equal 162 Ohms
• Tolerance must be ±1% or tighter
• Temperature coefficient must be ±100ppm/°C or better
• Operating temperature range must encompass or equal -55°C to 155°C

Mechanical Parameter Matching:

• Package format must be 1210 (3225 Metric)
• Physical dimensions must be compatible with 1210 footprint specifications
• Number of terminations must be 2

Compliance & Environmental Matching:

• RoHS3 compliance required
• MSL rating must be 1 (Unlimited) or equivalent
• REACH Unaffected status maintained

Power Rating Consideration: The main part is rated at 0.333W (1/3W). Substitute parts with equal or higher power ratings (0.5W / 1/2W) are functionally equivalent in applications requiring the 0.333W specification, as higher-rated components can safely operate at lower power levels without performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CRCW1210162RFKEA (Vishay Dale)

The CRCW1210162RFKEA is the preferred substitute for the RC3225F1620CS. Both components maintain identical electrical specifications (162 Ohms ±1%, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical compatibility (1210 package). The Vishay Dale part carries Active product status with AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 rating. The higher power rating (0.5W versus 0.333W) provides additional thermal margin in applications without introducing incompatibility.

Secondary Substitute: ERJ-14NF1620U (Panasonic)

The ERJ-14NF1620U meets all electrical and mechanical compatibility requirements with identical resistance, tolerance, temperature coefficient, and operating temperature specifications. This part carries AEC-Q200 automotive qualification and full compliance certifications. However, the product status is designated as "Not For New Designs," limiting its application to legacy system support or replacement scenarios where existing inventory must be maintained.

Substitution Constraints:

Both substitute parts are electrically and mechanically equivalent to the RC3225F1620CS. Selection between the main part and substitutes should be based on:

• Inventory availability and supply chain requirements
• Product lifecycle status (Active versus Not For New Designs)
• Automotive qualification requirements (AEC-Q200 certification)
• Packaging format requirements (Tape & Reel versus other formats)

Frequently Asked Questions (FAQ)

Q: Can the CRCW1210162RFKEA replace the RC3225F1620CS in existing designs?

A: Yes. Both components share identical electrical specifications (162 Ohms ±1%, ±100ppm/°C, -55°C to 155°C) and are packaged in the 1210 (3225 Metric) format. The CRCW1210162RFKEA's higher power rating (0.5W) is functionally compatible with applications designed for 0.333W operation.

Q: What is the difference between the 0.333W and 0.5W power ratings?

A: The power rating indicates maximum continuous power dissipation capability. A 0.5W-rated component can safely operate at 0.333W or lower without performance degradation. The higher rating provides additional thermal headroom and does not affect electrical performance in circuits designed for lower power dissipation.

Q: Why is the ERJ-14NF1620U marked "Not For New Designs"?

A: This designation indicates the part is in the mature or end-of-life phase of its product lifecycle. While the component remains functionally equivalent and available in inventory, Panasonic recommends using alternative parts for new design implementations. The ERJ-14NF1620U remains suitable for replacement, repair, and legacy system support.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RC3225F1620CS, CRCW1210162RFKEA, and ERJ-14NF1620U all carry ROHS3 Compliant status and are REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All three parts carry this rating, eliminating moisture-related storage constraints.

Q: Do the substitute parts have automotive qualifications?

A: The CRCW1210162RFKEA and ERJ-14NF1620U both carry AEC-Q200 automotive qualification. The RC3225F1620CS does not specify automotive qualification in the provided parameters. If automotive-grade components are required, the Vishay Dale or Panasonic parts are appropriate selections.

Q: Are there dimensional differences between the parts?

A: All three components use the 1210 (3225 Metric) package with nominal dimensions of 0.126" L x 0.098-0.100" W. Height variations are minimal (0.024" to 0.028" seated maximum), and all components are compatible with standard 1210 PCB footprints.
