RC3216F2102CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F2102CS is a 21 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor is designed for general-purpose applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 715 units currently in stock.

Substitute parts become necessary when the primary manufacturer part is unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified suppliers is needed. All substitute parts listed maintain electrical and mechanical compatibility with the RC3216F2102CS based on matching resistance value, tolerance, power rating, package dimensions, and operating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F2102CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (21 kOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C) must match exactly. Operating temperature range must encompass or equal -55°C to 155°C.

Mechanical Parameters: Package type must be 1206 (3216 Metric). Physical dimensions and height specifications must be compatible with PCB footprints designed for 1206 components.

Compliance Parameters: All substitute parts must maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status to ensure regulatory equivalence.

The substitute parts identified below satisfy all these criteria. Two parts are classified as Direct Manufacturer equivalents (RC1206FR-0721KL from YAGEO and CRCW120621K0FKEA from Vishay Dale), while one part is classified as Similar (ERJ-8ENF2102V from Panasonic Electronic Components) due to product status considerations.

Parameter Comparison

Engineering Selection Recommendations

RC1206FR-0721KL (YAGEO): This part is recommended as the primary direct substitute. It maintains Active product status, ensuring long-term availability and support. All electrical and mechanical parameters match the RC3216F2102CS exactly. The part is available in Tape & Reel packaging with 24,637 units in stock, providing robust supply chain continuity.

CRCW120621K0FKEA (Vishay Dale): This part qualifies as a direct substitute with Active product status. It includes AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Physical dimensions are identical to the main part. Inventory of 17,401 units supports consistent availability.

ERJ-8ENF2102V (Panasonic Electronic Components): This part meets all electrical and mechanical substitution criteria and includes AEC-Q200 automotive qualification. However, its product status is listed as "Not For New Designs," indicating that Panasonic is phasing this part out. While it remains functionally equivalent and is currently in stock (39,738 units), it should be selected only when the primary alternatives are unavailable or when existing designs require continuity with previously qualified components.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-0721KL be used as a direct replacement for RC3216F2102CS without PCB redesign?

A: Yes. Both parts share identical 1206 (3216 Metric) package specifications, matching footprint dimensions of 3.20mm length × 1.60mm width. No PCB layout modifications are required for substitution.

Q: What is the difference between the moisture resistance features listed for RC3216F2102CS and the substitute parts?

A: The RC3216F2102CS specifies "Moisture Resistant" as a feature. The CRCW120621K0FKEA and ERJ-8ENF2102V specify "Automotive AEC-Q200" features. All three parts maintain MSL Level 1 (Unlimited) rating, indicating equivalent moisture sensitivity performance. The AEC-Q200 designation on the Vishay and Panasonic parts represents additional automotive qualification testing, not a difference in moisture resistance.

Q: Are there packaging differences between these substitute parts?

A: The RC3216F2102CS is supplied in standard packaging (not specified as Tape & Reel). The RC1206FR-0721KL, CRCW120621K0FKEA, and ERJ-8ENF2102V are all supplied in Tape & Reel (TR) packaging. Tape & Reel packaging is standard for automated assembly processes and is compatible with pick-and-place equipment. If bulk or alternative packaging is required, contact the respective manufacturers.

Q: Why is ERJ-8ENF2102V marked as "Not For New Designs"?

A: "Not For New Designs" indicates that Panasonic is discontinuing this product line in favor of newer alternatives. While the part remains electrically and mechanically equivalent and is currently available, it should not be selected for new product designs. Use RC1206FR-0721KL or CRCW120621K0FKEA for new designs to ensure long-term supply availability.

Q: Do all substitute parts meet the same compliance requirements as the main part?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH Unaffected, and carry EAR99 ECCN classification, matching the RC3216F2102CS compliance profile exactly.

Q: What is the significance of the ±100ppm/°C temperature coefficient across all parts?

A: The temperature coefficient of ±100ppm/°C defines the maximum resistance change per degree Celsius across the operating temperature range. All substitute parts maintain this specification, ensuring equivalent thermal stability and predictable performance across -55°C to 155°C.
