RC3216F3401CS 3.4kΩ 1% 1/4W 1206 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RC3216F3401CS is a 3.4 kOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with 979 pieces currently in stock. The part is designed for general-purpose applications requiring moisture-resistant thick film construction with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing improves supply chain resilience, or when design requirements permit selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F3401CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3.4 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these mandatory parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. Cut Tape), and additional certifications (such as AEC-Q200 automotive qualification) do not affect functional substitutability for applications where the base electrical and thermal specifications are met.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: RC1206FR-073K4L (YAGEO)

The RC1206FR-073K4L is the preferred direct substitute for the RC3216F3401CS. Both parts share identical electrical specifications, thermal characteristics, and compliance certifications. YAGEO maintains Active product status with significantly higher inventory availability (23,960 pieces), ensuring supply chain continuity. The part is packaged in Tape & Reel format, standard for high-volume manufacturing environments.

Secondary Recommendations: CRCW12063K40FKEA (Vishay Dale) and RMCF1206FT3K40 (Stackpole)

Both CRCW12063K40FKEA and RMCF1206FT3K40 meet all mandatory electrical and mechanical parameters. These parts carry AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. Both maintain Active product status. CRCW12063K40FKEA offers Cut Tape packaging as an alternative to Tape & Reel. Inventory levels support consistent availability (11,469 and 11,975 pieces respectively).

Alternative Option: ERJ-8ENF3401V (Panasonic)

The ERJ-8ENF3401V is functionally equivalent across all electrical and mechanical parameters. However, this part carries "Not For New Designs" product status, indicating Panasonic has discontinued active development. While existing inventory is substantial (65,631 pieces), this part should be selected only when existing designs require component continuity or when supply constraints necessitate alternative sourcing. New designs should prioritize parts with Active status.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-073K4L replace RC3216F3401CS in existing designs?

A: Yes. RC1206FR-073K4L is a direct functional equivalent. Both parts share identical resistance (3.4 kOhms), tolerance (±1%), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). Physical dimensions vary slightly within 1206 package specification but do not affect PCB layout or electrical performance.

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 established by the Automotive Electronics Council. CRCW12063K40FKEA, ERJ-8ENF3401V, and RMCF1206FT3K40 carry this certification. RC3216F3401CS and RC1206FR-073K4L do not specify AEC-Q200 qualification. For non-automotive applications, both certified and non-certified parts are functionally equivalent. For automotive applications, AEC-Q200 certified parts provide documented reliability assurance.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect substitutability?

A: No. Packaging format affects handling, storage, and assembly line compatibility but does not alter electrical or mechanical performance. RC3216F3401CS, RC1206FR-073K4L, ERJ-8ENF3401V, and RMCF1206FT3K40 are supplied in Tape & Reel format. CRCW12063K40FKEA is available in Cut Tape & Digi-Reel format. Selection should align with manufacturing equipment capabilities and inventory management procedures.

Q: Why is ERJ-8ENF3401V marked "Not For New Designs"?

A: "Not For New Designs" indicates Panasonic has transitioned this part to end-of-life status and is not actively developing or promoting new applications. Existing inventory remains available for legacy design support. New designs should prioritize parts with Active status (RC1206FR-073K4L, CRCW12063K40FKEA, RMCF1206FT3K40) to ensure long-term supply availability and manufacturer support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RC1206FR-073K4L, CRCW12063K40FKEA, ERJ-8ENF3401V, RMCF1206FT3K40) are ROHS3 compliant, matching the RC3216F3401CS compliance status. All parts are REACH Unaffected and classified under ECCN EAR99 for export control purposes.

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

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions (typically 30°C / 85% relative humidity). No special moisture control or baking procedures are required before soldering. All substitute parts share this MSL 1 rating, ensuring identical handling requirements.
