Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S03F1433V are qualified based on the following criteria:

• Resistance value: 143 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitutes meet these core electrical and mechanical parameters. Automotive AEC-Q200 qualification is present in the main part and most substitutes, though this certification is not mandatory for all substitute candidates. Packaging format (Tape & Reel) is consistent across all parts.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and MSL Level 1 rating, meeting the core environmental and regulatory requirements of the ERJ-S03F1433V.

For applications requiring automotive AEC-Q200 qualification, the following parts are directly equivalent:

• ERJ-3EKF1433V (Panasonic)
• AC0603FR-07143KL (YAGEO)
• CRCW0603143KFKEA (Vishay Dale)
• RMCF0603FT143K (Stackpole Electronics Inc)

For applications where AEC-Q200 qualification is not required, CR0603-FX-1433ELF (Bourns Inc.) and RC0603FR-07143KL (YAGEO) are functionally equivalent alternatives with identical electrical specifications and package dimensions.

Inventory availability varies significantly across manufacturers, with RC0603FR-07143KL offering the highest stock level at 299,920 units, followed by RMCF0603FT143K at 395,992 units.

Frequently Asked Questions (FAQ)

Q: Can I substitute ERJ-S03F1433V with any of the listed parts without circuit redesign?

A: Yes. All listed substitutes share identical resistance value (143 kOhms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Physical dimensions are equivalent within standard manufacturing tolerances for the 0603 package.

Q: What is the difference between parts with and without AEC-Q200 qualification?

A: AEC-Q200 is an automotive qualification standard indicating the part has undergone additional reliability testing for automotive applications. Parts with AEC-Q200 (ERJ-3EKF1433V, AC0603FR-07143KL, CRCW0603143KFKEA, RMCF0603FT143K) are suitable for automotive and high-reliability applications. Parts without AEC-Q200 (CR0603-FX-1433ELF, RC0603FR-07143KL) are suitable for general industrial and consumer applications.

Q: Are there dimensional differences between substitute parts?

A: Nominal dimensions are identical at 0603 (1608 Metric). Minor variations exist in maximum seated height: most parts specify 0.022" (0.55mm), while CRCW0603143KFKEA specifies 0.020" (0.50mm). These variations fall within standard 0603 package tolerances and do not affect PCB assembly compatibility.

Q: What does MSL Level 1 mean?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This applies to all listed parts.

Q: Which substitute offers the best availability?

A: RC0603FR-07143KL (YAGEO) has the highest inventory at 299,920 units, followed by RMCF0603FT143K (Stackpole Electronics Inc) at 395,992 units. For automotive applications requiring AEC-Q200, RMCF0603FT143K offers the best availability.
