Engineering Selection Recommendations

All three parts—RCS3216F1744CS (Samsung Electro-Mechanics), CRCW12061M74FKEA (Vishay Dale), and RC1206FR-071M74L (YAGEO)—are functionally equivalent for applications requiring a 1.74 MOhms ±1% 0.25W 1206 chip resistor.

Samsung Electro-Mechanics RCS3216F1744CS: Features anti-sulfur and moisture-resistant properties. Active product status with ROHS3 compliance and MSL Level 1.

Vishay Dale CRCW12061M74FKEA: Includes Automotive AEC-Q200 qualification, suitable for automotive-grade applications. Active product status with ROHS3 compliance and MSL Level 1. Seated height is 0.024" (0.60mm), the lowest among the three options.

YAGEO RC1206FR-071M74L: Features moisture-resistant properties. Active product status with ROHS3 compliance and MSL Level 1. Dimensional length is 3.10mm, slightly smaller than the Samsung part.

Selection between these parts depends on application-specific requirements such as automotive qualification needs or space constraints. All parts meet the same electrical and compliance specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW12061M74FKEA replace RCS3216F1744CS in any application?

A: Yes, provided the application does not require specific anti-sulfur properties beyond standard moisture resistance. Both parts meet identical electrical specifications (1.74 MOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and are packaged in 1206 (3216 Metric) with ROHS3 compliance and MSL Level 1.

Q: What is the difference in physical dimensions between these parts?

A: RCS3216F1744CS and CRCW12061M74FKEA both measure 0.126" L x 0.063" W (3.20mm x 1.60mm). RC1206FR-071M74L measures 0.122" L x 0.063" W (3.10mm x 1.60mm). Seated heights are 0.66mm (Samsung), 0.60mm (Vishay), and 0.65mm (YAGEO). These minor variations are within standard 1206 package tolerances.

Q: Are all three parts suitable for high-temperature applications?
