RCS3216F3483CS 348kΩ 1% 1/4W 1206 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RCS3216F3483CS is a 348 kOhms ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component is classified as Active product status with anti-sulfur and moisture-resistant characteristics. The part is ROHS3 compliant and operates across the temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size and form factor), and environmental performance characteristics (operating temperature range, moisture sensitivity level, and compliance certifications).

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3483CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 348 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Equivalence Requirements:

• Package designation: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)
• REACH Status: REACH Unaffected (minimum requirement)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in specific feature sets (anti-sulfur, moisture resistant, automotive AEC-Q200 certification) do not disqualify substitution eligibility when all core electrical and mechanical parameters match.

Engineering Selection Recommendations

Primary Selection (Active Status):

For new designs and ongoing production, select from parts with Active product status:

• CRCW1206348KFKEA (Vishay Dale): Active status with automotive AEC-Q200 certification. Highest inventory availability (10,623 pcs). Suitable for automotive and industrial applications requiring AEC-Q200 qualification.
• RC1206FR-07348KL (YAGEO): Active status with moisture-resistant characteristics. Highest inventory availability (31,989 pcs). Suitable for general industrial and consumer applications.
• RMCS1206FT348K (Stackpole Electronics Inc): Active status with anti-sulfur characteristics. Lower inventory (986 pcs). Suitable for applications in corrosive environments.
• RCS3216F3483CS (Samsung Electro-Mechanics): Active status with anti-sulfur and moisture-resistant characteristics. Current inventory (698 pcs).

Secondary Selection (Legacy Applications):

• ERJ-8ENF3483V (Panasonic Electronic Components): Marked as "Not For New Designs" but remains in production with high inventory (22,764 pcs). Use only for replacement in existing equipment or legacy system maintenance where design freeze is required.

All listed parts maintain identical electrical performance and mechanical compatibility. Selection between active-status alternatives should be based on application-specific requirements (automotive certification, environmental resistance features), supply chain availability, and cost considerations.

Frequently Asked Questions (FAQ)

Q1: Can I substitute RCS3216F3483CS with CRCW1206348KFKEA in my circuit?

A: Yes. Both parts are electrically and mechanically equivalent with matching 348 kOhms resistance, ±1% tolerance, 0.25W power rating, and 1206 package specification. The CRCW1206348KFKEA includes automotive AEC-Q200 certification, which provides additional qualification for automotive applications but does not prevent use in general industrial or consumer applications.

Q2: What is the difference between the anti-sulfur feature in RCS3216F3483CS and RMCS1206FT348K versus the moisture-resistant feature in RC1206FR-07348KL?

A: Anti-sulfur and moisture-resistant are distinct environmental protection features. Anti-sulfur protection addresses corrosion from sulfur-containing compounds in high-pollution or industrial environments. Moisture-resistant protection addresses humidity and condensation exposure. Both features are compatible with the core electrical specifications. Selection depends on the specific environmental conditions of the application.

Q3: Why is ERJ-8ENF3483V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and optimization of this product line. While the part remains available and functionally equivalent, it should not be selected for new circuit designs. Use ERJ-8ENF3483V only for replacement in existing equipment or when design freeze requirements mandate component consistency.

Q4: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel packaging, which is standard for automated assembly processes. Packaging format is consistent across all alternatives.

Q5: Do all substitute parts meet ROHS3 compliance?

A: Yes. All listed parts, including the main part RCS3216F3483CS, are ROHS3 compliant and REACH unaffected. Compliance status is uniform across all alternatives.

Q6: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity limitations and requires no special moisture control during storage, handling, or assembly. All listed parts carry this rating, eliminating moisture-related constraints in manufacturing and storage.

Q7: Can I use ERJ-8ENF3483V as a direct replacement if my current design uses RCS3216F3483CS?

A: Yes, from an electrical and mechanical standpoint. However, verify that your supply chain and design documentation policies permit use of components marked "Not For New Designs." If your application is in active development or subject to design change control, select an Active-status alternative instead.

Q8: How do physical dimension variations affect substitution?

A: All parts conform to the 1206 (3216 Metric) package specification. Minor variations in length (0.122" to 0.126"), width (0.061" to 0.063"), and height (0.024" to 0.028") fall within standard package tolerances and do not affect PCB layout, footprint compatibility, or electrical performance. These variations are acceptable for direct substitution.
