RCS3216F3010CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F3010CS is a 301 Ohm ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component features anti-sulfur and moisture-resistant construction with a temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements mandate specific certifications such as automotive AEC-Q200 qualification or alternative RoHS compliance status.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3010CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

Resistance value: 301 Ohms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
Moisture sensitivity level: 1 (Unlimited)
Number of terminations: 2

All substitute parts listed meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard tolerances, packaging format (Tape & Reel), and optional certifications (AEC-Q200) do not preclude substitution. Product status and compliance certifications are secondary considerations that may influence selection based on application requirements.

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

Parts with Active product status and ROHS3 compliance are suitable for unrestricted substitution: CR1206-FX-3010ELF (Bourns Inc.), RC1206FR-07301RL (YAGEO), and RMCF1206FT301R (Stackpole Electronics Inc.). These maintain full compliance with current environmental regulations and are supported for ongoing production.

Automotive-Qualified Substitutes:

For applications requiring AEC-Q200 automotive qualification, select from: AC1206FR-07301RL (YAGEO), CRCW1206301RFKEA (Vishay Dale), or RMCF1206FT301R (Stackpole Electronics Inc.). All three maintain Active status and ROHS3 compliance.

Conditional Substitutes:

CRCW1206301RFKTA (Vishay Dale) is electrically and mechanically equivalent but carries RoHS non-compliance and REACH-affected status. Use only when legacy design requirements or specific supply chain constraints mandate this part.

Obsolescence Consideration:

ERJ-8ENF3010V (Panasonic Electronic Components) carries "Not For New Designs" status despite ROHS3 compliance and AEC-Q200 qualification. This part is suitable only for sustaining production of existing designs or repair applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F3010CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts share identical electrical specifications (301 Ω ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical package (1206/3216 Metric). Physical dimension variations are within standard manufacturing tolerances and do not affect PCB layout or assembly processes.

Q: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. Parts without this certification (RCS3216F3010CS, CR1206-FX-3010ELF, RC1206FR-07301RL) are suitable for general industrial and consumer applications. Parts with AEC-Q200 (AC1206FR-07301RL, CRCW1206301RFKEA, CRCW1206301RFKTA, ERJ-8ENF3010V, RMCF1206FT301R) are qualified for automotive use but may be substituted in non-automotive applications.

Q: Why is CRCW1206301RFKTA marked as RoHS non-compliant?

A: CRCW1206301RFKTA does not meet ROHS3 environmental compliance requirements. This part should be used only when legacy designs or specific supply agreements require it. For new designs, select ROHS3-compliant alternatives.

Q: What does "Not For New Designs" mean for ERJ-8ENF3010V?

A: This designation indicates the manufacturer has discontinued active development and support for this part. While existing inventory may be available and the part remains electrically functional, Panasonic does not recommend its use in new product designs. Use only for sustaining production of existing designs or repair applications.

Q: Are there any differences in moisture sensitivity between these parts?

A: No. All parts listed carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture baking requirements. Moisture sensitivity is not a differentiating factor for substitution.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. Mixed sourcing from multiple manufacturers is permissible from a technical standpoint. Verify procurement, quality assurance, and supply chain policies with your organization before implementing multi-source strategies.
