476KXM050M Equivalent & Substitute Parts Reference

Part Overview

The 476KXM050M is a 47 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as Active status and serves general-purpose applications requiring polarized capacitive energy storage. The KXM series delivers 2000 hours of operational life at 105°C with an operating temperature range of -55°C to 105°C.

Substitute parts are necessary when the primary part becomes unavailable due to inventory constraints, supply chain disruptions, or when alternative sourcing is required while maintaining electrical and mechanical compatibility within specified parameters.

Engineering Selection Recommendations

476KXM050M (Cornell Dubilier / Illinois Capacitor)

Primary selection for new designs and active production. Active product status ensures continued availability and manufacturer support. ROHS3 compliant and suitable for general-purpose applications.

ELXZ500ELL470MFB5D (Chemi-Con)

Direct electrical and mechanical equivalent with Active product status. Carries AEC-Q200 automotive qualification rating. Height dimension is 0.512" (13.00mm), which is 0.020" taller than the primary part. Suitable for applications where automotive-grade reliability is required. Lower impedance specification (450 mOhms) compared to primary part (1.132 Ohms) indicates superior high-frequency performance characteristics.

UKA1H470MED (Nichicon)

Electrical and mechanical equivalent with identical height to primary part (0.492"). Product status is Obsolete, indicating discontinued manufacturing. Inventory availability is currently high (3577 Pcs), but future sourcing is not guaranteed. Suitable only for legacy system maintenance or when existing stock is available. Not recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can ELXZ500ELL470MFB5D be used as a direct replacement for 476KXM050M?

A: Yes. Both parts share identical electrical specifications (47 µF, ±20%, 50 V, 2000 Hrs @ 105°C) and mechanical parameters (lead spacing 0.098", radial can package, through-hole mounting). The height difference of 0.020" (13.00mm vs 12.50mm) must be verified against PCB layout constraints. Both are ROHS3 compliant.

Q: What is the difference between the substitute parts?

A: ELXZ500ELL470MFB5D is Active status with automotive qualification (AEC-Q200). UKA1H470MED is Obsolete status. ELXZ500ELL470MFB5D has slightly greater height (0.512" vs 0.492"). UKA1H470MED matches the original height exactly.

Q: Is UKA1H470MED suitable for new product designs?

A: No. UKA1H470MED carries Obsolete product status, indicating discontinued manufacturing. While current inventory is available, future sourcing cannot be guaranteed. New designs should use 476KXM050M or ELXZ500ELL470MFB5D.

Q: Do all three parts have the same lead spacing?

A: Yes. All three parts have 0.098" (2.50mm) lead spacing and are compatible with identical PCB footprints from a lead-spacing perspective. Height differences must be evaluated separately.

Q: Are there compliance differences between the three parts?

A: All three parts are ROHS3 compliant and REACH unaffected. ELXZ500ELL470MFB5D carries additional AEC-Q200 automotive qualification. This does not restrict its use in non-automotive applications.

Q: What is the significance of the impedance difference between 476KXM050M and ELXZ500ELL470MFB5D?

A: The primary part specifies 1.132 Ohms impedance, while ELXZ500ELL470MFB5D specifies 450 mOhms. Lower impedance indicates better high-frequency performance. This difference is within normal manufacturing variation for aluminum electrolytic capacitors and does not affect substitution compatibility for general-purpose applications.
