Engineering Selection Recommendations

The RC1206FR-079M1L from YAGEO is a direct functional equivalent to the RCS3216F915CS. Both components are Active products with ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current and future applications. The dimensional variations (0.04mm length difference, 0.01mm height difference) fall within standard manufacturing tolerances for 1206 package resistors and do not impact PCB layout or assembly processes.

Selection between these parts should be based on availability, supply chain considerations, and packaging requirements. The RCS3216F915CS is supplied in standard packaging, while the RC1206FR-079M1L is available in Tape & Reel format, which may influence procurement decisions for high-volume manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-079M1L be used as a direct replacement for RCS3216F915CS in existing designs?

A: Yes. Both components share identical electrical specifications (9.1 MOhms, ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and package type (1206). Dimensional variations are within standard manufacturing tolerances and do not affect circuit performance or PCB compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Samsung vs. YAGEO) and packaging format (standard vs. Tape & Reel). The RCS3216F915CS includes anti-sulfur properties, while the RC1206FR-079M1L specifies moisture resistance. Both provide environmental protection suitable for industrial applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the RCS3216F915CS and RC1206FR-079M1L are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Does the 0.04mm length difference affect PCB layout?

A: No. The length variation (3.20mm vs. 3.10mm) is within standard 1206 package tolerances and does not impact footprint design, assembly, or electrical performance.

Q: Which part should be selected for new designs?

A: Selection depends on supply availability and packaging requirements. For high-volume production, the RC1206FR-079M1L in Tape & Reel format may offer manufacturing advantages. For standard applications, either part is functionally equivalent.

Q: Are there any temperature or environmental limitations when substituting these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 155°C) and share MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent performance in all specified environmental conditions.
