Engineering Selection Recommendations

All three substitute parts maintain Active product status and full compliance with ROHS3 and REACH requirements, ensuring regulatory compatibility with the original SLPX472M080E7P3.

SLPX472M080H3P3 shares identical ESR characteristics (71 mOhm @ 120Hz) with the main part and belongs to the same SLPX series. Physical dimensions differ, with a larger diameter (35.00 mm) but reduced height (30.00 mm). This part is suitable for applications where vertical space is constrained. Ripple current performance at high frequency (5.15 A @ 20 kHz) closely matches the original specification.

380LX472M080K042 features reduced ESR (65 mOhm @ 120Hz) compared to the main part, resulting in lower heat dissipation and improved efficiency. Physical dimensions remain similar to the original (30.00 mm diameter, 42.00 mm height). This part belongs to the 380LX series and is suitable for applications prioritizing thermal performance.

380LX472M080J052 also features reduced ESR (65 mOhm @ 120Hz) and belongs to the 380LX series. Physical dimensions differ significantly, with a smaller diameter (25.00 mm) but greater height (52.00 mm). This part is suitable for applications with horizontal space constraints but adequate vertical clearance.

Selection between substitutes depends on available board space and thermal requirements. All parts maintain equivalent electrical performance within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can SLPX472M080H3P3 be used as a direct replacement for SLPX472M080E7P3?

A: Yes. Both parts share identical capacitance (4700 µF), voltage rating (80 V), tolerance (±20%), ESR (71 mOhm @ 120Hz), lifetime (3000 Hrs @ 85°C), operating temperature range (-40°C to 85°C), lead spacing (10.00 mm), and mounting type (Through Hole, Radial Can - Snap-In). Physical dimensions differ; SLPX472M080H3P3 has a larger diameter (35.00 mm) and reduced height (30.00 mm). Verify available board space before substitution.

Q: What is the difference between the 380LX series substitutes and the original SLPX series?

A: Both series are manufactured by Cornell Dubilier Electronics and meet all mandatory electrical equivalence parameters. The 380LX series parts feature lower ESR (65 mOhm @ 120Hz) compared to the SLPX series (71 mOhm @ 120Hz), resulting in reduced equivalent series resistance and improved thermal performance. Physical dimensions vary between individual part numbers within each series.

Q: Are there physical dimension constraints when selecting a substitute?

A: Yes. While all substitute parts maintain the same lead spacing (10.00 mm) and mounting type (Through Hole), diameter and height vary. SLPX472M080E7P3 measures 30.00 mm diameter × 40.00 mm height. SLPX472M080H3P3 measures 35.00 mm diameter × 30.00 mm height. 380LX472M080K042 measures 30.00 mm diameter × 42.00 mm height. 380LX472M080J052 measures 25.00 mm diameter × 52.00 mm height. Verify PCB layout compatibility before selection.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 Compliant and REACH Unaffected, matching the original SLPX472M080E7P3 compliance profile.

Q: What is the significance of ESR variation between substitutes?

A: ESR (Equivalent Series Resistance) affects heat generation and ripple current handling. Lower ESR values (65 mOhm in 380LX series) result in reduced heat dissipation compared to higher ESR values (71 mOhm in SLPX series). Both values are within acceptable operating parameters for this capacitance and voltage class. Selection depends on thermal management requirements of the specific application.

Q: Can ripple current ratings differ between the main part and substitutes?

A: Yes. Ripple current ratings vary slightly between parts due to physical design differences. SLPX472M080E7P3 supports 4.23 A @ 120 Hz and 5.29 A @ 20 kHz. Substitute parts support comparable ratings within a narrow range (4.09-4.23 A @ 120 Hz and 4.7-5.29 A @ 20 kHz). Verify application ripple current requirements fall within the selected part's rated specification.
