Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR10EZPF2002 is determined by the following critical parameters:

• Resistance value: 20 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package footprint: 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 required)
• Automotive Rating: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The RCS080520K0FKEA from Vishay Dale qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. The power rating differential (0.5W versus 0.4W) represents a higher capability margin and does not restrict substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR10EZPF2002 and RCS080520K0FKEA maintain identical electrical specifications and automotive compliance certifications. Selection between these parts should be based on availability and supply chain requirements. The RCS080520K0FKEA offers a higher power rating (0.5W versus 0.4W) within the same physical footprint, providing additional thermal margin in applications. Both parts are ROHS3 compliant and carry AEC-Q200 automotive qualification, making them suitable for equivalent use in automotive circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RCS080520K0FKEA replace ESR10EZPF2002 in existing designs?

A: Yes. Both parts share identical resistance value (20 kOhms), tolerance (±1%), package footprint (0805), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive rating (AEC-Q200). The higher power rating of the substitute part does not restrict compatibility.

Q: What is the significance of the power rating difference?

A: The ESR10EZPF2002 is rated at 0.4W while the RCS080520K0FKEA is rated at 0.5W. This difference indicates the substitute part can dissipate more thermal energy. In applications designed for the original 0.4W part, the 0.5W substitute provides additional thermal headroom without affecting electrical performance.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are ROHS3 compliant, meeting automotive industry standards for reliability and environmental compliance.

Q: Do the physical dimensions differ between these parts?

A: Both parts use the 0805 (2012 Metric) package with identical length and width (0.079" L x 0.049" W / 2.00mm x 1.25mm). The seated height differs slightly: ESR10EZPF2002 at 0.026" (0.65mm) maximum and RCS080520K0FKEA at 0.020" (0.50mm) maximum. This variation is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: What certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
