SLP472M050A4P3 Equivalent & Substitute Parts

Part Overview

The Cornell Dubilier Electronics (CDE) SLP472M050A4P3 is a 4700 µF 50 V aluminum electrolytic capacitor in radial, can snap-in package. This component is actively manufactured and serves general-purpose energy storage and filtering applications requiring 3000-hour lifetime at 105°C operation. Alternative equivalent models become necessary when specific inventory constraints, performance enhancements, or form-factor compatibility with system layouts require component flexibility within the electrical and mechanical parameter envelope.

Substitute Part Grouping Explanation

Substitution eligibility for the SLP472M050A4P3 is determined by strict electrical and mechanical parameter matching:

Mandatory Electrical Parameters:

Capacitance: 4700 µF (exact)
Voltage Rating: 50 V (exact)
Tolerance: ±20% (exact)
Operating Temperature Range: -40°C to 105°C (matching or superior)

Mandatory Mechanical Parameters:

Package Type: Radial, Can - Snap-In
Mounting Type: Through Hole
Lead Spacing: 0.394" (10.00 mm)
Polarization: Polar

All three identified substitute parts satisfy these core requirements. Variations in secondary parameters such as can diameter, height, ESR, ripple current ratings, and lifetime at temperature represent engineering trade-offs within the application's tolerance band. Secondary parameter differences do not disqualify a substitute when primary electrical and mechanical parameters align.

Engineering Selection Recommendations

All substitute parts are actively manufactured and ROHS3 compliant, satisfying environmental and regulatory requirements.

SLP472M050C5P3: This part shares the identical series designation (SLP0712TE 750W) and ESR specification with the main part. It offers improved footprint efficiency with reduced can diameter (25.00 mm vs. 22.00 mm primary) and height (35.00 mm vs. 45.00 mm primary), making it suitable for space-constrained mounting layouts where can dimensions permit substitution. Inventory availability is significantly higher (23,234 units vs. 647 units for the primary part).

381LX472M050A012: This part provides the most compact footprint in the substitute group, with the smallest can diameter (35.00 mm) and lowest seated height (27.00 mm). However, the larger diameter represents a dimensional increase compared to the primary part. ESR data is not provided for this variant. This part is suitable when height constraints are the primary geometric concern. Inventory availability is strong (1,111 units).

LP472M050H3P3: This part operates at reduced lifetime specification (1000 Hrs @ 105°C vs. 3000 Hrs for other options) and lower ripple current rating (2.27 A @ 120 Hz). The lower ESR characteristic (71 mOhm) may benefit low-impedance applications. This part is suitable only when application duty cycle tolerates reduced thermal lifetime. Inventory is available (1,146 units).

Selection among substitutes depends on primary design constraints: can diameter and height availability within the board layout, required ripple current handling, and thermal cycle expectations.

Frequently Asked Questions (FAQ)

Q: Can SLP472M050C5P3 directly replace SLP472M050A4P3 without circuit redesign? A: Yes, when mounting space permits the identical lead spacing (10.00 mm) and increased can diameter (25.00 mm vs. 22.00 mm). The identical electrical specifications (4700 µF, 50 V, ±20%, 3000 Hrs @ 105°C) ensure functional equivalence.

Q: What is the primary trade-off when selecting 381LX472M050A012? A: The 381LX provides the most compact height footprint (27.00 mm) at the cost of increased can diameter (35.00 mm). ESR specification is not documented for this variant. Lead spacing remains identical at 10.00 mm, supporting drop-in replacement when horizontal board space is available.

Q: Is LP472M050H3P3 suitable for high-temperature long-duration applications? A: No. The LP series is rated for only 1000 hours at 105°C, compared to 3000 hours for the other three parts. Use this part only in applications where thermal lifetime requirements do not exceed 1000 hours at maximum operating temperature.

Q: Do all substitutes maintain the same lead spacing? A: Yes. All four parts (primary and substitutes) are specified with 0.394" (10.00 mm) lead spacing, ensuring identical PCB footprint compatibility in the radial direction.

Q: Are all parts RoHS and REACH compliant? A: Yes. All four parts are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for restricted substance control.
