Parameter Comparison

Engineering Selection Recommendations

All three parts—RC1608F1244CS (Samsung Electro-Mechanics), RC0603FR-071M24L (YAGEO), and CRCW06031M24FKEA (Vishay Dale)—maintain Active product status and satisfy identical electrical and mechanical specifications for 1.24 MOhms ±1% 0.1W 0603 chip resistor applications.

RC1608F1244CS (Samsung Electro-Mechanics): Primary specification with moisture-resistant thick film construction. Supplied in Cut Tape packaging format. Suitable for standard industrial and consumer applications requiring ROHS3 compliance.

RC0603FR-071M24L (YAGEO): Direct electrical equivalent supplied in Tape & Reel format. Identical electrical performance and temperature characteristics. Appropriate for high-volume production environments where reel packaging is standard.

CRCW06031M24FKEA (Vishay Dale): Functionally equivalent with additional Automotive AEC-Q200 qualification. Supplied in Tape & Reel format. Suitable for automotive applications and environments requiring automotive-grade component certification. Dimensions show minor variation (1.55mm x 0.85mm vs. 1.60mm x 0.80mm) and height (0.50mm vs. 0.55mm), remaining within 0603 package tolerance specifications.

Selection between these parts depends on packaging requirements (Cut Tape vs. Tape & Reel), supply chain availability, and automotive qualification necessity.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-071M24L replace RC1608F1244CS directly on the PCB?

A: Yes. Both parts share identical electrical specifications (1.24 MOhms ±1%, 0.1W, ±100ppm/°C), operate across -55°C to 155°C, and conform to 0603 (1608 Metric) package dimensions. The primary difference is packaging format (Cut Tape vs. Tape & Reel), which does not affect PCB placement or electrical performance.

Q: What is the difference between the Samsung and Vishay Dale versions?

A: The CRCW06031M24FKEA (Vishay Dale) includes Automotive AEC-Q200 qualification, making it suitable for automotive applications. Physical dimensions show minor variation within 0603 tolerance specifications. Electrical performance is identical across all three parts.
