Equivalent & Substitute Parts for 477HSM063M

Part Overview

The 477HSM063M is a 470 µF, 63 V aluminum electrolytic capacitor in radial can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as obsolete, with a rated lifetime of 2000 hours at 125°C and an equivalent series resistance of 353 mOhm at 120 Hz. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing production and maintenance applications requiring 470 µF, 63 V radial aluminum electrolytic capacitors with compatible mechanical and electrical characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the 477HSM063M is determined by the following mandatory parameters:

Primary Compatibility Criteria:

Capacitance: 470 µF (exact match required)
Voltage Rating: 63 V minimum (equal or higher voltage rating acceptable)
Tolerance: ±20% (standard tolerance band)
Package: Radial, Can (through-hole configuration)
Lead Spacing: 0.295" (7.50 mm) (PCB footprint match)
Diameter: 0.630" (16.00 mm) (mechanical envelope)
Polarization: Polar (polarity orientation maintained)

Secondary Compatibility Considerations:

Height (Seated Max): 1.043" to 1.063" (minor height variation acceptable within typical PCB clearance tolerances)
Operating Temperature Range: Must encompass application requirements
Ripple Current Ratings: Must meet or exceed circuit ripple current demands

Parts meeting all primary criteria are classified as direct substitutes. Parts with voltage ratings exceeding 63 V (such as UBW1K471MHD at 80 V) are electrically compatible but represent an upgrade in voltage margin.

Engineering Selection Recommendations

Direct Substitutes (63 V Rating, Identical Voltage Class):

MAL214058471E3 and MAL214068471E3 (Vishay Beyschlag/Draloric/BC Components, 140 RTM Series) are direct electrical and mechanical substitutes for the 477HSM063M. Both parts maintain 470 µF capacitance, ±20% tolerance, 63 V voltage rating, and identical lead spacing and diameter. Both are ROHS3 compliant and active products. MAL214058471E3 and MAL214068471E3 offer extended lifetime ratings of 4000 hours at 125°C compared to the original 2000 hours, with lower impedance values (55 mOhms) providing improved high-frequency performance. Operating temperature range extends to -55°C, exceeding the original -40°C lower limit.

Frequently Asked Questions (FAQ)

Q: Can UBW1K471MHD (80 V) be used in place of 477HSM063M (63 V)?

A: Yes. The UBW1K471MHD operates at 80 V rating, which is compatible with circuits designed for 63 V operation. The higher voltage rating provides additional safety margin and does not create electrical incompatibility. Mechanical compatibility is maintained through identical lead spacing (0.295" / 7.50 mm) and diameter (0.630" / 16.00 mm).

Q: What is the difference between MAL214058471E3 and MAL214068471E3?

A: Both parts are from Vishay's 140 RTM series with identical electrical specifications: 470 µF, ±20% tolerance, 63 V rating, 4000 hours @ 125°C lifetime, 55 mOhms impedance, and -55°C to 125°C operating range. Both maintain identical mechanical dimensions and lead spacing. These parts are cross-compatible substitutes for each other and for the 477HSM063M.

Q: Will the height difference between 1.043" and 1.063" affect PCB assembly?

A: The height difference of 0.020" (0.50 mm) is within standard PCB clearance tolerances for through-hole radial capacitors. Verify available vertical clearance in the target application. If clearance is constrained, UBX1J471MHL maintains the original 1.043" height specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts listed (MAL214058471E3, MAL214068471E3, UBW1K471MHD, UBX1J471MHL, and 63RX30470M16X25) are ROHS3 compliant.

Q: Which substitute offers the best ripple current performance?

A: The 63RX30470M16X25 (Rubycon RX30) provides the highest ripple current ratings: 1.125 A @ 120 Hz and 1.5 A @ 100 kHz. This part is suitable for applications with elevated ripple current demands.

Q: Can I use these substitutes in automotive applications?

A: The 63RX30470M16X25 is specifically qualified for automotive use under AEC-Q200 standards. UBW1K471MHD and UBX1J471MHL are designated for automotive applications. MAL214058471E3 and MAL214068471E3 are general-purpose parts suitable for non-automotive applications.

Q: What is the impedance specification, and why does it matter?

A: Impedance represents the total opposition to AC current flow at a specific frequency. Lower impedance values (55 mOhms in MAL214058471E3 and MAL214068471E3) indicate better high-frequency performance and lower voltage ripple. The original 477HSM063M specified 353 mOhm ESR at 120 Hz; substitute parts with lower impedance provide improved filtering characteristics.

Q: Are these parts pin-compatible with the 477HSM063M?

A: Yes. All substitute parts maintain identical lead spacing (0.295" / 7.50 mm) and radial can package configuration, ensuring direct PCB footprint compatibility.
