LPX471M250A4P3 Equivalent & Substitute Parts

Part Overview

The LPX471M250A4P3 is a 470 µF, 250 V aluminum electrolytic capacitor in a radial, can snap-in package manufactured by Cornell Dubilier Electronics (CDE). This general-purpose capacitor is actively produced and maintained in stock. Identifying equivalent and substitute parts is necessary when the primary part number is unavailable, when specific performance characteristics (such as lower ESR or extended lifetime) are required for the application, or when alternative packaging formats become necessary to meet design requirements.

Key Parameters

Substitute Part Grouping Explanation

Valid substitutes for the LPX471M250A4P3 must satisfy the following electrical and mechanical parameters:

• Capacitance: 470 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)

The following substitute parts meet these core substitution criteria: SLPX471M250E1P3 and 380LX471M250J042. These parts differ in secondary performance characteristics including ESR (Equivalent Series Resistance), ripple current ratings, physical dimensions (diameter and height), and rated lifetime at operating temperature, but maintain full electrical and mechanical compatibility within the specified design constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts (LPX471M250A4P3, 380LX471M250J042, and SLPX471M250E1P3) are actively manufactured, ROHS3 compliant, and REACH unaffected. Selection among these substitutes depends on specific design requirements:

LPX471M250A4P3 serves as the primary reference part with a 1000-hour lifetime rating at 85°C and standard form factor dimensions.

380LX471M250J042 offers significantly improved performance with a 3000-hour lifetime rating and substantially lower ESR (39 mOhm versus 423 mOhm), making it suitable for applications requiring reduced heat dissipation and extended service life. The slightly larger diameter (25.00 mm) and comparable height (42.00 mm) present a minimal footprint change.

SLPX471M250E1P3 provides a 3000-hour lifetime rating with the same ESR as the primary part (423 mOhm) but offers a more compact height profile (25.00 mm versus 45.00 mm). This makes it the preferred choice for space-constrained designs, despite the increased diameter (30.00 mm).

Frequently Asked Questions (FAQ)

Q: Can SLPX471M250E1P3 substitute for LPX471M250A4P3 on the same PCB? A: SLPX471M250E1P3 maintains the same lead spacing (10.00 mm) and can be mounted in the same hole pattern. However, the physical diameter increases from 22.00 mm to 30.00 mm, and the height decreases from 45.00 mm to 25.00 mm. PCB layout validation is required to confirm clearance around the larger diameter.

Q: What is the primary difference between 380LX471M250J042 and the other substitutes? A: The 380LX471M250J042 features significantly lower ESR (39 mOhm versus 423 mOhm), reducing heat generation and improving performance in high-ripple-current applications. Its 3000-hour lifetime also exceeds the primary part's 1000-hour rating.

Q: Are all substitute parts RoHS3 compliant? A: All listed substitute parts (LPX471M250A4P3, 380LX471M250J042, and SLPX471M250E1P3) are ROHS3 compliant and REACH unaffected, ensuring regulatory compliance for current manufacturing standards.

Q: Do the dimensional differences affect electrical performance? A: Dimensional variations among these snap-in capacitors do not affect their electrical parameters (capacitance, voltage rating, or tolerance). Selection based on dimensions is driven by mechanical fit constraints in the specific application, not electrical performance.

Q: What is the significance of Moisture Sensitivity Level (MSL) being "Not Applicable" for SLPX471M250E1P3? A: The SLPX471M250E1P3 designation indicates MSL as "Not Applicable," while LPX471M250A4P3 and 380LX471M250J042 both carry MSL-1 (Unlimited). This difference reflects manufacturing specifications but does not affect practical handling or storage under standard industrial conditions.
