Engineering Selection Recommendations

RC1206FR-071M82L (YAGEO): Direct electrical and mechanical equivalent to RC3216F1824CS. Maintains all critical specifications including resistance, tolerance, power rating, temperature coefficient, and operating range. ROHS3 compliant with MSL Level 1 rating. Supplied in Tape & Reel packaging. Dimensional variation (3.10mm vs 3.20mm length) remains within 1206 package class tolerance and does not affect PCB footprint compatibility.

CRCW12061M82FKEA (Vishay Dale): Functionally equivalent with identical electrical specifications. Includes AEC-Q200 automotive qualification rating, providing additional reliability certification beyond base specification. ROHS3 compliant with MSL Level 1 rating. Supplied in Tape & Reel packaging. Seated height is 0.024" (0.60mm) versus 0.026" (0.66mm) on main part, remaining within acceptable PCB assembly clearance margins for 1206 package class.

Both substitutes are Active status products with full compliance documentation and maintain functional equivalence for direct circuit substitution.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-071M82L replace RC3216F1824CS in all applications?

A: Yes. Both parts share identical electrical specifications (1.82 MOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and are packaged in 1206 (3216 Metric) form factor. Dimensional tolerance variation (3.10mm vs 3.20mm length) does not affect PCB footprint compatibility or assembly processes.

Q: What is the difference between CRCW12061M82FKEA and the other substitutes?

A: CRCW12061M82FKEA includes AEC-Q200 automotive qualification, indicating enhanced reliability testing and qualification for automotive applications. All other electrical and mechanical parameters remain equivalent. This part is suitable for applications requiring automotive-grade components.

Q: Are packaging format differences significant?

A: RC3216F1824CS is supplied in bulk packaging, while RC1206FR-071M82L and CRCW12061M82FKEA are supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact component performance or electrical characteristics.
