Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07402KL replace RC1608F4023CS directly? A: Yes. RC0603FR-07402KL matches all critical electrical parameters (402 kOhms ±1%, 0.1W, ±100ppm/°C), operates across the identical temperature range (-55°C to 155°C), uses the same 0603 package format, and maintains ROHS3 compliance. Physical dimensions are identical at 1.60mm x 0.80mm.

Q: What is the difference between standard and AEC-Q200 qualified parts? A: AEC-Q200 qualified parts (AC0603FR-07402KL, CRCW0603402KFKEA, ERJ-3EKF4023V, RMCF0603FT402K) meet automotive industry reliability standards. These parts are suitable for automotive applications and environments requiring enhanced qualification testing. Non-automotive qualified parts (CR0603-FX-4023ELF, RC0603FR-07402KL) are suitable for standard industrial and consumer applications.

Q: Are there dimensional differences between substitute parts? A: Most substitutes maintain the standard 0603 package dimensions of 1.60mm x 0.80mm with 0.55mm maximum seated height. CRCW0603402KFKEA and CRCW0603402KFKTA show minor dimensional variations (1.55mm x 0.85mm and 1.60mm x 0.85mm respectively) with 0.50mm maximum seated height. These variations remain within standard 0603 package tolerances and do not affect PCB footprint compatibility.

Q: Which substitute offers the best inventory availability? A: RC0603FR-07402KL (YAGEO) provides the highest inventory at 1,662,746 pieces. For automotive-qualified alternatives, ERJ-3EKF4023V (Panasonic Electronic Components) offers 84,622 pieces.

Q: Is CRCW0603402KFKTA suitable for new designs? A: CRCW0603402KFKTA is RoHS non-compliant and REACH Affected. This part is not recommended for new designs unless specific legacy system requirements or RoHS exemptions apply. CRCW0603402KFKEA (ROHS3 Compliant) is the preferred Vishay Dale alternative.

Q: Do all substitutes maintain the same moisture sensitivity level? A: Yes. All listed substitute parts maintain MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
