RCS3216F3480CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F3480CS is a 348 Ohm ±1% 0.25W (1/4W) thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component features anti-sulfur and moisture-resistant construction, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical specifications, package dimensions, and mechanical compatibility within the 1206 form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3480CS is determined by strict adherence to the following parameters:

Primary Substitution Criteria:

• Resistance value: 348 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W) minimum
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel), and optional certifications (such as AEC-Q200 automotive qualification) do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

CR1206-FX-3480ELF (Bourns Inc.), CRCW1206348RFKEA (Vishay Dale), RC1206FR-07348RL (YAGEO), and RMCF1206FT348R (Stackpole Electronics Inc.) are all active production parts with full ROHS3 compliance and MSL 1 rating. These parts are suitable for direct substitution in applications requiring the 348 Ohm ±1% 0.25W 1206 resistor specification.

Higher Power Alternative:

CRCW1206348RFKEAHP (Vishay Dale) provides 0.75W (3/4W) power rating in the same 1206 package with identical electrical specifications. This part is suitable for applications requiring enhanced pulse withstanding capability or higher power dissipation margins while maintaining the same resistance and tolerance values.

Legacy Status:

ERJ-8ENF3480V (Panasonic Electronic Components) is marked "Not For New Designs" and should be avoided in new product development. Existing designs using this part may continue operation, but migration to active alternatives is recommended for long-term supply chain stability.

Automotive Applications:

CRCW1206348RFKEA, CRCW1206348RFKEAHP, ERJ-8ENF3480V, and RMCF1206FT348R carry AEC-Q200 automotive qualification. These parts are suitable for automotive and high-reliability applications requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206348RFKEAHP (0.75W) be used as a direct replacement for RCS3216F3480CS (0.25W)?

A: Yes. The CRCW1206348RFKEAHP meets all electrical specifications (348 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C) and package requirements (1206). The higher power rating (0.75W vs. 0.25W) provides additional thermal margin and does not create incompatibility. Physical dimensions remain within 1206 package tolerance.

Q: What is the difference between parts marked "Active" and "Not For New Designs"?

A: Parts with "Active" status are in current production and recommended for new designs. ERJ-8ENF3480V is marked "Not For New Designs," indicating Panasonic has transitioned this product line. Existing inventory may be available, but new product development should use active alternatives to ensure long-term supply availability.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All identified substitute parts are supplied in Tape & Reel format, suitable for automated assembly processes. The RCS3216F3480CS main part is supplied in standard packaging; verify specific packaging requirements with your procurement specification.

Q: Do substitute parts with AEC-Q200 certification affect circuit performance?

A: No. AEC-Q200 certification indicates automotive-grade qualification and enhanced reliability testing. Parts with this certification (CRCW1206348RFKEA, CRCW1206348RFKEAHP, ERJ-8ENF3480V, RMCF1206FT348R) meet or exceed the electrical and environmental specifications of non-certified alternatives. They are suitable for both automotive and general industrial applications.

Q: What is MSL 1 (Unlimited) moisture sensitivity level?

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

Q: Can physical dimension variations between substitute parts affect PCB layout?

A: No. All parts conform to the 1206 (3216 Metric) package specification with maximum dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm). Minor variations in seated height (0.024" to 0.030") do not affect PCB footprint compatibility or assembly processes.
