RCS3216F163CS Equivalent & Substitute Parts

Part Overview

The RCS3216F163CS is a 16 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is RoHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating.

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. Substitute parts enable design flexibility, supply chain alternatives, and procurement optimization while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence: Resistance value (16 kOhms), tolerance (±1%), and power rating (0.25W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must match or exceed the main part specifications.

Mechanical Compatibility: Package designation (1206 / 3216 Metric) and number of terminations (2) must be identical. Physical dimensions must be compatible with 1206 footprints.

Environmental & Compliance: RoHS3 compliance and MSL Level 1 rating are required. REACH status and ECCN classification must align with regulatory requirements.

Composition & Construction: Thick film construction is the specified technology. Moisture resistance is a baseline requirement; additional features (anti-sulfur, automotive AEC-Q200) are noted but do not disqualify substitutes lacking these enhancements.

All four substitute parts meet these criteria and are direct functional equivalents to the RCS3216F163CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-1602ELF (Bourns Inc.) and RC1206FR-0716KL (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and continued manufacturer support. CR1206-FX-1602ELF provides Tape & Reel packaging identical to the main part. RC1206FR-0716KL offers Cut Tape and Digi-Reel packaging options, providing flexibility for different procurement volumes.

Automotive-Qualified Alternative:

CRCW120616K0FKEA (Vishay Dale) is suitable for applications requiring automotive-grade components. This part carries AEC-Q200 qualification and maintains Active product status. Selection of this part is appropriate when automotive reliability standards are specified in design requirements.

Legacy Consideration:

ERJ-8ENF1602V (Panasonic Electronic Components) carries "Not For New Designs" status. This part is electrically and mechanically equivalent but should not be selected for new product development. Use only when existing inventory must be maintained or legacy system repairs are required.

Compliance Verification:

All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. HTSUS classification (8533.21.0030) is consistent across all parts.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1602ELF directly replace RCS3216F163CS in existing designs?

A: Yes. CR1206-FX-1602ELF is electrically and mechanically equivalent. Both parts share identical resistance (16 kOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Physical dimensions are compatible with 1206 footprints. The primary difference is packaging format (Tape & Reel for both), with CR1206-FX-1602ELF lacking the anti-sulfur feature of the Samsung part. For standard applications, this difference is not functionally significant.

Q: What is the difference between the substitute parts?

A: All four substitutes meet core electrical and mechanical specifications. Key differences are: (1) Bourns CR1206-FX-1602ELF and YAGEO RC1206FR-0716KL are standard industrial-grade parts with Active status; (2) Vishay Dale CRCW120616K0FKEA includes automotive AEC-Q200 qualification; (3) Panasonic ERJ-8ENF1602V is automotive-qualified but marked "Not For New Designs"; (4) Packaging formats vary (Tape & Reel vs. Cut Tape / Digi-Reel). Selection depends on application requirements and procurement preferences.

Q: Is the 1206 package compatible across all parts?

A: Yes. All parts use the 1206 (3216 Metric) package designation. Physical dimensions are compatible: main part and substitutes measure 0.126" L × 0.063" W (3.20mm × 1.60mm) with maximum seated heights between 0.024" and 0.030" (0.60mm to 0.75mm). These variations are within standard PCB footprint tolerances and do not affect interchangeability.

Q: Should I use CRCW120616K0FKEA for non-automotive applications?

A: CRCW120616K0FKEA is suitable for any application requiring 16 kOhms ±1% 0.25W 1206 resistors. The automotive AEC-Q200 qualification indicates enhanced reliability testing and is not detrimental to non-automotive use. Selection should be based on availability, cost, and packaging requirements rather than automotive qualification alone.

Q: Why is ERJ-8ENF1602V marked "Not For New Designs"?

A: "Not For New Designs" status indicates that Panasonic has discontinued active development and marketing of this part. While the part remains electrically and mechanically equivalent, it should not be specified in new product designs due to uncertain long-term availability. Use only for legacy system maintenance or when existing inventory must be consumed.

Q: Are there differences in moisture resistance between parts?

A: All parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. The Samsung RCS3216F163CS specifies "anti-sulfur" and "moisture resistant" features; Bourns CR1206-FX-1602ELF and YAGEO RC1206FR-0716KL specify "moisture resistant"; Panasonic and Vishay parts do not explicitly list moisture resistance in provided specifications. All parts meet the same MSL standard and are suitable for standard industrial environments.

Q: What packaging options are available?

A: CR1206-FX-1602ELF, CRCW120616K0FKEA, and ERJ-8ENF1602V are supplied in Tape & Reel (TR) format. RC1206FR-0716KL is available in Cut Tape (CT) and Digi-Reel® format. Tape & Reel is standard for high-volume automated assembly; Cut Tape and Digi-Reel accommodate lower volumes and manual handling. Selection depends on production volume and assembly process requirements.
