Engineering Selection Recommendations

477KXM100M (Cornell Dubilier / Illinois Capacitor)

Primary selection for general-purpose applications. Active product status ensures continued manufacturer support and availability. ROHS3 compliance and EAR99 classification meet standard regulatory requirements. Suitable for new designs and ongoing production.

ELXV101ELL471ML40S (Chemi-Con LXV Series)

Direct manufacturer equivalent with Active product status. AEC-Q200 automotive qualification provides additional reliability assurance. Lower impedance (41 mOhms) and higher ripple current capability (2.2 A @ 100 kHz) compared to the main part indicate improved performance characteristics. Mechanical compatibility confirmed with 0.220" height variance within acceptable tolerance. Recommended for applications requiring automotive-grade reliability or when higher ripple current performance is beneficial.

UPM2A471MHD (Nichicon UPM Series)

Parametric equivalent with AEC-Q200 automotive qualification. Product status is Not For New Designs, indicating this part is suitable for replacement and legacy applications but not recommended for new design implementations. REACH Status is REACH Affected, requiring compliance verification for specific end-use applications. Impedance (47 mOhms) and ripple current performance (1.76 A @ 120 Hz, 2.2 A @ 10 kHz) fall between the main part and the Chemi-Con substitute. Mechanical compatibility confirmed with identical height specification.

Frequently Asked Questions (FAQ)

Q: Can ELXV101ELL471ML40S be used as a direct replacement for 477KXM100M in existing designs?

A: Yes. Both parts share identical electrical specifications (470 µF, ±20%, 100 V, 5000 Hrs @ 105°C) and mechanical parameters (lead spacing, diameter, through-hole mounting). The 0.020" height difference (41.50mm vs. 42.00mm) is within standard PCB layout tolerances. The Chemi-Con part offers improved performance with lower impedance and higher ripple current capability.

Q: What is the significance of the AEC-Q200 rating on the substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. Parts bearing this rating have undergone additional reliability testing and are approved for automotive applications. This certification does not restrict use in general-purpose applications; it indicates enhanced quality assurance. Both substitute parts carry AEC-Q200 qualification.

Q: Why is UPM2A471MHD marked as "Not For New Designs"?

A: This product status indicates the manufacturer is phasing out this part number. It remains available for replacement and legacy applications but should not be selected for new design implementations. For new designs, select either the 477KXM100M (Active status) or ELXV101ELL471ML40S (Active status).

Q: Are there mechanical constraints that would prevent substitution?

A: No. All three parts share identical lead spacing (0.295" / 7.50mm), diameter (0.630" / 16.00mm), and through-hole mounting configuration. Height variation between parts is 0.020" (0.50mm), which is negligible for standard PCB design. All parts fit within the same mechanical envelope.

Q: How do the impedance and ripple current differences affect circuit performance?

A: Lower impedance and higher ripple current ratings indicate improved high-frequency performance and thermal stability. The Chemi-Con ELXV101ELL471ML40S exhibits the lowest impedance (41 mOhms) and highest ripple current (2.2 A @ 100 kHz), making it suitable for applications with demanding ripple current requirements. The main part (477KXM100M) and Nichicon substitute (UPM2A471MHD) provide adequate performance for standard general-purpose applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts carry ROHS3 Compliant status, meeting current environmental and hazardous substance restrictions. All parts are also classified as EAR99 for export control purposes.

Q: What is the difference between the main part's general-purpose application rating and the substitutes' automotive ratings?

A: Automotive-rated parts (AEC-Q200) undergo additional qualification testing for temperature cycling, vibration, and reliability. These parts are suitable for both automotive and general-purpose applications. General-purpose rated parts meet standard industrial requirements. Selection between them depends on application requirements and desired reliability margin, not on electrical or mechanical compatibility.
