Engineering Selection Recommendations

Primary Selection: RC3216F3094CS (Samsung Electro-Mechanics)

Use the original Samsung part when:

Supply chain continuity is prioritized
Existing inventory (842 units) is available
Design validation has been completed with this specific manufacturer

Substitute Selection: RC1206FR-073M09L (YAGEO)

Use the YAGEO substitute when:

Samsung part availability is constrained
Lead time reduction is required (5929 units in stock)
Tape & Reel packaging format is acceptable for production processes
Both parts maintain identical electrical performance and regulatory compliance

Both parts are Active products with ROHS3 compliance and REACH Unaffected status, ensuring regulatory requirements are met in either selection. The dimensional variations (0.1mm length difference, 0.01mm height difference) fall within standard PCB assembly tolerances for 1206 package components and do not affect circuit functionality or thermal performance.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-073M09L be used as a direct replacement for RC3216F3094CS on the PCB?

A: Yes. Both components share identical electrical specifications (3.09 MOhms, ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and are packaged in the 1206 (3216 Metric) form factor. Dimensional variations are within standard assembly tolerances and do not affect PCB layout or component placement.

Q: What is the difference in packaging between these two parts?

A: The RC3216F3094CS is supplied in standard packaging format, while the RC1206FR-073M09L is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both RC3216F3094CS and RC1206FR-073M09L are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Does the slight dimensional difference affect thermal performance?

A: No. The dimensional variations (length 3.20mm vs 3.10mm, height 0.66mm vs 0.65mm) are within standard manufacturing tolerances for 1206 package resistors and do not impact thermal dissipation or electrical performance at the 0.25W power rating.

Q: What is the MSL rating and why does it matter?

A: Both parts have MSL 1 (Unlimited), meaning they have unlimited shelf life and require no special moisture control during storage or handling. This simplifies inventory management and reduces component preparation time before assembly.

Q: Can these parts be mixed in the same production batch?

A: Yes. Both parts meet identical electrical and mechanical specifications, allowing them to be used interchangeably within the same circuit design and production run without affecting circuit performance or reliability.
