RCS3216F4020CS Equivalent & Substitute Parts

Part Overview

The RCS3216F4020CS is a 402 Ohm ±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 suitable for general industrial and consumer applications requiring precision resistive elements.

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F4020CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 402 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 ~ 155°C
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in packaging format (Tape & Reel versus bulk) do not affect functional substitutability. Product status and application-specific certifications (such as AEC-Q200 for automotive) represent additional qualifications that may exceed base requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-4020ELF (Bourns Inc.) and RC1206FR-07402RL (YAGEO) are recommended as primary substitutes. Both components maintain Active product status, ensuring continued availability and manufacturer support. CRCW1206402RFKEA (Vishay Dale) is also Active and includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability standards.

Secondary Substitute (Legacy Status):

ERJ-8ENF4020V (Panasonic Electronic Components) carries "Not For New Designs" product status. This classification indicates the manufacturer is phasing out this component line. While electrically and mechanically equivalent, this part should be selected only when existing inventory constraints or design continuity requirements necessitate its use. New circuit designs should prioritize Active-status alternatives.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. Selection between substitutes should prioritize Active product status for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-4020ELF replace RCS3216F4020CS directly?

A: Yes. Both components share identical electrical specifications (402 Ohms ±1%, 0.25W), thermal characteristics (±100ppm/°C, -55°C to 155°C), and package dimensions (1206 / 3216 Metric). The primary difference is packaging format (Tape & Reel versus bulk) and manufacturer. Direct PCB footprint compatibility is confirmed.

Q: What is the significance of AEC-Q200 certification on CRCW1206402RFKEA?

A: AEC-Q200 is an automotive industry qualification standard. CRCW1206402RFKEA meets this certification, making it suitable for automotive applications requiring enhanced reliability testing. Non-automotive applications do not require this certification, but its presence does not prevent use in general industrial circuits.

Q: Why is ERJ-8ENF4020V marked "Not For New Designs"?

A: This designation indicates Panasonic is discontinuing this product line. While the component remains electrically and mechanically equivalent, manufacturers recommend selecting Active-status alternatives for new circuit designs to ensure long-term supply availability and manufacturer support.

Q: Are there dimensional differences between substitute parts?

A: Minor variations exist within the 1206 package specification. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm) and height from 0.024" to 0.030" (0.60mm to 0.75mm). These variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility or functional performance.

Q: Do all substitutes maintain the same moisture sensitivity rating?

A: Yes. All listed substitutes carry MSL 1 (Unlimited) rating, identical to the RCS3216F4020CS. This ensures equivalent performance in standard manufacturing environments without special moisture control requirements.

Q: Which substitute offers the best long-term availability?

A: RC1206FR-07402RL (YAGEO) demonstrates the highest current inventory (276,264 pieces) and Active product status, indicating strong market availability. CRCW1206402RFKEA (Vishay Dale) with 21,579 pieces and CR1206-FX-4020ELF (Bourns) with 27,593 pieces also provide reliable supply channels.
