RC3216F6814CS Equivalent & Substitute Parts

Part Overview

The RC3216F6814CS is a 6.81 megohm thick film chip resistor manufactured by Samsung Electro-Mechanics. This 1206 (3216 metric) surface mount device is rated for 0.25W (1/4W) power dissipation with ±1% tolerance and operates across the temperature range of -55°C to 155°C. The component is moisture resistant and classified as ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). The part maintains active product status with 1148 units currently in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or specific application requirements.

Substitute Part Grouping Explanation

Substitution of the RC3216F6814CS is permissible with the RMCF1206FT6M81 based on the following alignment of critical parameters:

Electrical Equivalence:

• Identical resistance value: 6.81 MOhms
• Identical tolerance: ±1%
• Identical power rating: 0.25W (1/4W)
• Identical composition: Thick Film

Mechanical Compatibility:

• Identical package designation: 1206 (3216 Metric)
• Identical number of terminations: 2
• Matching physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Compatible height specifications (0.026" vs 0.028" maximum seated height)

Compliance & Environmental:

• Both ROHS3 compliant
• Both REACH unaffected
• Both classified as MSL 1 (unlimited moisture sensitivity)
• Both operate across -55°C to 155°C temperature range

The substitute part introduces automotive-grade AEC-Q200 qualification and a higher temperature coefficient (±200ppm/°C versus ±100ppm/°C), which represents an enhancement in application scope rather than a limitation.

Engineering Selection Recommendations

Primary Selection (RC3216F6814CS): The Samsung Electro-Mechanics RC3216F6814CS remains the primary choice for applications requiring moisture-resistant thick film construction with standard industrial specifications. This part is active in production with adequate inventory (1148 units) and meets all ROHS3 and REACH compliance requirements.

Substitute Selection (RMCF1206FT6M81): The Stackpole Electronics RMCF1206FT6M81 serves as a direct functional equivalent with the addition of AEC-Q200 automotive qualification. This substitute is appropriate for applications requiring automotive-grade reliability or when Samsung inventory becomes unavailable. The higher temperature coefficient (±200ppm/°C) is acceptable in circuits where the original ±100ppm/°C specification is not a critical design constraint. The substitute maintains identical electrical performance, mechanical fit, and environmental compliance while offering enhanced qualification status.

Both parts are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity classification, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the RMCF1206FT6M81 be used as a direct replacement for the RC3216F6814CS on existing PCBs?

A: Yes. Both components share identical resistance (6.81 MOhms), tolerance (±1%), power rating (0.25W), package designation (1206), and operating temperature range (-55°C to 155°C). The maximum seated height difference (0.026" versus 0.028") falls within standard PCB assembly tolerances and does not affect placement or soldering.

Q: What is the significance of the AEC-Q200 qualification on the substitute part?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. The RMCF1206FT6M81 carries this qualification, making it suitable for automotive applications. The RC3216F6814CS does not specify this qualification, limiting its use in automotive designs requiring AEC-Q200 compliance.

Q: Does the higher temperature coefficient of the substitute part affect circuit performance?

A: The RMCF1206FT6M81 has a temperature coefficient of ±200ppm/°C compared to ±100ppm/°C for the RC3216F6814CS. This difference is acceptable in applications where the original specification does not mandate the tighter ±100ppm/°C tolerance. Circuit designers must verify that the wider temperature coefficient does not violate specific design requirements before substitution.

Q: Are there packaging differences between these parts?

A: Yes. The RC3216F6814CS is supplied in bulk packaging, while the RMCF1206FT6M81 is supplied in Tape & Reel (TR) format. Both formats are compatible with standard pick-and-place assembly equipment. Tape & Reel packaging is standard for high-volume production and offers improved handling efficiency.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RC3216F6814CS and RMCF1206FT6M81 are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). They meet identical environmental and regulatory requirements for industrial and commercial applications.

Q: What is the inventory status for each part?

A: The RC3216F6814CS has 1148 units in stock. The RMCF1206FT6M81 has 1133 units in stock. Both parts maintain active product status with comparable availability.
