Substitute Part Grouping Explanation

Substitution of the ESR10EZPF2003 is permissible when the alternative component meets the following criteria:

• Resistance value: 200 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match or better required)
• Automotive Rating: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Power Rating: Equal to or greater than 0.4W (higher ratings acceptable)

The RCS0805200KFKEA from Vishay Dale qualifies as a direct substitute, meeting all mandatory electrical and mechanical parameters while offering a higher power rating of 0.5W.

Parameter Comparison

Engineering Selection Recommendations

The RCS0805200KFKEA is a qualified substitute for the ESR10EZPF2003 based on the following engineering criteria:

Both components are AEC-Q200 rated, confirming suitability for automotive applications. Both maintain ROHS3 compliance and identical electrical specifications including resistance, tolerance, temperature coefficient, and operating temperature range. The substitute component offers a higher power rating (0.5W versus 0.4W), which provides additional thermal margin in the application. The substitute also features a lower seated height (0.020" versus 0.026"), which may provide advantages in space-constrained PCB layouts. Both components are thick film construction with identical package dimensions and termination count, ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the RCS0805200KFKEA replace the ESR10EZPF2003 in automotive applications?

A: Yes. Both components carry AEC-Q200 automotive qualification, identical resistance and tolerance specifications, and matching operating temperature ranges. The substitute is fully compatible for automotive use.

Q: Does the higher power rating of the RCS0805200KFKEA affect circuit performance?

A: No. A higher power rating does not degrade performance. The 0.5W rating of the substitute provides additional thermal headroom compared to the 0.4W rating of the original part, making it suitable for the same application.

Q: Are the physical dimensions identical between these parts?

A: The length and width are identical at 0.079" x 0.049" (2.00mm x 1.25mm). The seated height differs slightly, with the substitute measuring 0.020" (0.50mm) maximum versus 0.026" (0.65mm) for the original. Both fit the 0805 package standard and are PCB compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ESR10EZPF2003 and RCS0805200KFKEA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both carry identical REACH and ECCN classifications.

Q: What is the temperature coefficient specification for these resistors?

A: Both components specify ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range, ensuring identical temperature stability performance.
