Regulatory Compliance: Both parts satisfy ROHS3 and REACH requirements, ensuring compatibility with current environmental and safety standards.

Product Status: Both components maintain Active product status, confirming ongoing manufacturer support and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-079M1L replace RC3216F915CS in existing designs?

A: Yes. Both components are electrically and mechanically equivalent across all critical parameters: 9.1 MOhms ±1% resistance, 0.25W power rating, 1206 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. PCB footprints are compatible within standard manufacturing tolerances.

Q: What are the dimensional differences between these parts?

A: Length differs slightly (3.20mm vs 3.10mm) and seated height differs minimally (0.66mm vs 0.65mm). These variations fall within standard 1206 package tolerances and do not affect PCB assembly or electrical performance.

Q: Are there packaging considerations when switching from RC3216F915CS to RC1206FR-079M1L?

A: RC1206FR-079M1L is supplied in Tape & Reel (TR) format, which is standard for automated pick-and-place assembly. RC3216F915CS uses standard packaging. Verify your assembly process compatibility with TR format before procurement.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC3216F915CS and RC1206FR-079M1L are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent regulatory and environmental performance.

Q: Which part should be selected for new designs?

A: RC1206FR-079M1L is recommended for new designs due to higher inventory availability, Tape & Reel packaging compatibility with modern assembly processes, and equivalent technical specifications. RC3216F915CS remains suitable for replacement or repair applications where Samsung components are specified.
