RC3225F2941CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F2941CS is a 2.94 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 and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified when components share identical electrical specifications (resistance value, tolerance, temperature coefficient) and compatible mechanical packaging, while potentially differing in power rating, supplier packaging format, or product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F2941CS is determined by strict alignment of the following parameters:

Critical Matching Parameters (Non-Negotiable):

• Resistance value: 2.94 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Number of terminations: 2

Compatible Variation Parameters:

• Power rating: Equal or greater than 0.333W
• Supplier packaging format: May differ (bulk, tape & reel, etc.)
• Product lifecycle status: May vary
• Certifications and features: May include additional qualifications (e.g., AEC-Q200)

The identified substitute ERJ-14NF2941U meets all critical matching parameters while providing a higher power rating (0.5W vs. 0.333W), making it electrically and mechanically compatible for direct substitution in applications where the RC3225F2941CS is specified.

Parameter Comparison

Engineering Selection Recommendations

RC3225F2941CS Selection Criteria:

• Primary choice for new designs requiring Active product status
• Suitable for applications with standard moisture resistance requirements
• Recommended when supplier continuity with Samsung Electro-Mechanics is required
• Appropriate for designs with 0.333W power dissipation specifications

ERJ-14NF2941U Selection Criteria:

• Electrically and mechanically compatible direct substitute
• Provides higher power rating (0.5W) for applications with increased thermal margin
• Includes AEC-Q200 automotive qualification for automotive-grade applications
• Product status is "Not For New Designs," limiting use to legacy system support or inventory replacement scenarios
• Suitable for existing designs currently using this part number

Compliance Considerations: Both parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. Selection between these parts should prioritize product lifecycle requirements and application-specific power dissipation needs rather than compliance factors.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2941U be used as a direct replacement for RC3225F2941CS in new designs?

A: ERJ-14NF2941U is electrically and mechanically compatible with RC3225F2941CS. However, ERJ-14NF2941U carries "Not For New Designs" product status. For new designs, RC3225F2941CS is the appropriate choice due to its Active product status. ERJ-14NF2941U is suitable only for legacy system support or inventory replacement in existing applications.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Manufacturer—Samsung Electro-Mechanics vs. Panasonic Electronic Components; (2) Power rating—0.333W vs. 0.5W; (3) Product status—Active vs. Not For New Designs; (4) Features—Moisture Resistant vs. Automotive AEC-Q200. Electrical specifications (resistance, tolerance, temperature coefficient, operating range) and package format are identical.

Q: Are the physical dimensions compatible?

A: Yes. Both parts use the 1210 (3225 Metric) package format. Dimensional variance is negligible: length differs by 0.002" (0.05mm) and height by 0.002" (0.04mm). These tolerances fall within standard PCB layout and assembly specifications.

Q: Does the higher power rating of ERJ-14NF2941U affect circuit performance?

A: No. A higher power rating (0.5W vs. 0.333W) provides additional thermal margin and does not alter electrical performance. The component will function identically in circuits designed for 0.333W dissipation. The higher rating only indicates greater thermal capacity.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC3225F2941CS and ERJ-14NF2941U are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: What packaging formats are available for these parts?

A: RC3225F2941CS is supplied in standard packaging (format not specified in data). ERJ-14NF2941U is available in Tape & Reel (TR) format. Confirm packaging requirements with your procurement specifications before ordering.

Q: Can I use ERJ-14NF2941U in automotive applications?

A: ERJ-14NF2941U includes AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. RC3225F2941CS does not carry this certification. If automotive qualification is required, ERJ-14NF2941U is the appropriate choice, subject to product lifecycle considerations.
