478LMB063M2ED Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The 478LMB063M2ED is a 4700 µF, 63 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the LMB series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high capacitance density in a compact through-hole package. The part is Active status and ROHS3 compliant. Substitute parts are identified when original inventory is unavailable, when alternative manufacturers are preferred for supply chain resilience, or when enhanced performance characteristics (such as extended lifetime ratings) are required for specific application demands.

Tray packaging (861140786018) provides organized component arrangement for automated assembly processes. Electrical and mechanical specifications are identical; packaging choice depends on manufacturing process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts (LGY1J472MELC30, 381LX472M063A022, 861140786018, LGU1J472MELC) are ROHS3 compliant and REACH Unaffected, maintaining regulatory equivalence with the original 478LMB063M2ED.

Q: Which substitute part has the best availability?

A: LGU1J472MELC (Nichicon) has the highest inventory at 3107 Pcs, followed by 381LX472M063A022 (CDE) at 1750 Pcs, LGY1J472MELC30 (Nichicon) at 1349 Pcs, and 861140786018 (Würth Elektronik) at 897 Pcs.

Q: Can I use 381LX472M063A022 if the original part is unavailable?

A: Yes. 381LX472M063A022 is a parametric equivalent with identical electrical specifications (4700 µF, 63 V, ±20%, 3000 Hrs @ 105°C) and mechanical dimensions. It is manufactured by Cornell Dubilier Electronics and maintains ROHS3 compliance.

Q: What is the significance of the ESR specification in 478LMB063M2ED?

A: The ESR (Equivalent Series Resistance) of 105.821 mOhm @ 120 Hz is provided for the original part. Substitute parts do not specify ESR values in the provided data. ESR affects ripple current handling and heat dissipation characteristics. For applications where ESR is a critical parameter, the original part specification should be consulted.

Q: Are the ripple current ratings interchangeable among all parts?

A: Ripple current ratings vary among the parts. The original 478LMB063M2ED specifies 2.81 A @ 120 Hz. Substitutes range from 2.6 A to 3.0 A @ 120 Hz. All parts are rated for general-purpose applications. For applications with specific ripple current requirements, the individual part specifications should be evaluated.

Q: What does "Active" product status mean?

A: Active status indicates that the part is currently manufactured and available for purchase. All parts listed (original and substitutes) maintain Active status, ensuring ongoing availability and manufacturer support.
