Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F1544CS and RC1206FR-071M54L are qualified substitutes based on matching electrical specifications, identical package dimensions within standard 1206 tolerances, and equivalent compliance certifications. Selection between these parts should be based on:

Availability & Inventory: The RC1206FR-071M54L offers higher inventory availability (5768 units) compared to the RCS3216F1544CS (1060 units), providing supply chain flexibility.

Packaging Format: The RCS3216F1544CS is supplied in bulk packaging, while the RC1206FR-071M54L is supplied in Tape & Reel format. Packaging selection depends on assembly process requirements and handling procedures.

Compliance Equivalence: Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical Moisture Sensitivity Level 1 ratings, ensuring equivalent environmental and regulatory performance.

Physical Dimensions: Minor length variations (3.20mm vs 3.10mm) and height variations (0.66mm vs 0.65mm) fall within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-071M54L be used as a direct replacement for RCS3216F1544CS?

A: Yes. Both parts share identical electrical specifications (1.54 MOhms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and package type (1206/3216 Metric). Physical dimensions vary within standard package 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), packaging format (bulk vs Tape & Reel), and minor dimensional variations. Electrical performance and compliance certifications are identical.

Q: Are there any compatibility concerns with PCB assembly?

A: No. Both parts conform to the 1206 package standard with compatible footprints. The 0.1mm length difference and 0.01mm height difference are within standard manufacturing tolerances and do not affect placement, soldering, or assembly processes.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and rated at Moisture Sensitivity Level 1 (Unlimited). They meet identical regulatory and environmental requirements.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain requirements and packaging preferences. Both parts are Active products with equivalent technical performance. The RC1206FR-071M54L offers higher inventory availability and Tape & Reel packaging suitable for automated assembly.

Q: Are the anti-sulfur properties of the RCS3216F1544CS critical for substitution?

A: The RCS3216F1544CS specifies anti-sulfur and moisture-resistant features, while the RC1206FR-071M54L specifies moisture-resistant properties. Both parts are rated at MSL 1 (Unlimited), indicating equivalent moisture protection. Application-specific requirements for sulfur resistance should be evaluated independently.
