Engineering Selection Recommendations

Direct Substitution (Mechanical and Electrical Equivalence):

The 250USG470MEFCSN25X25 (Rubycon USG series) and LAR2E471MELA35 (Nichicon LAR series) are direct substitutes for the LPX471M250C5P3. Both maintain identical capacitance, voltage rating, tolerance, lead spacing, and diameter specifications. Both are ROHS3 compliant and Active status. The 250USG470MEFCSN25X25 offers extended lifetime (3000 Hrs @ 85°C) with minimal height variation (27.00 mm vs. 35.00 mm). The LAR2E471MELA35 provides extended operating temperature range (-40 to 105°C) and extended lifetime at elevated temperature (2000 Hrs @ 105°C).

Performance-Enhanced Substitution (CDE Series):

The SLPX471M250E1P3 (CDE SLPX series) maintains identical ESR characteristics (423 mOhm @ 120Hz) and lifetime extension (3000 Hrs @ 85°C). However, this part features a larger diameter (30.00 mm) and reduced height (25.00 mm), requiring PCB layout verification for mechanical fit.

The 380LX471M250J042 (CDE 380LX series) offers significant ESR reduction (39 mOhm @ 120Hz) and extended lifetime (3000 Hrs @ 85°C), suitable for applications requiring lower impedance performance. This part has increased height (42.00 mm), requiring clearance verification.

All substitute parts are Active status and ROHS3 compliant, meeting regulatory requirements equivalent to the LPX471M250C5P3.

Frequently Asked Questions (FAQ)

Q: Can the SLPX471M250E1P3 be used as a direct replacement for the LPX471M250C5P3?

A: The SLPX471M250E1P3 is electrically equivalent (470 µF, 250 V, ±20%, 423 mOhm ESR) and mechanically compatible in lead spacing (10.00 mm) and mounting type (through-hole, snap-in). However, the diameter is 30.00 mm versus 25.00 mm, and height is 25.00 mm versus 35.00 mm. PCB layout must accommodate these dimensional differences before substitution.

Q: What is the primary difference between the 380LX471M250J042 and the LPX471M250C5P3?

A: Both parts are 470 µF, 250 V aluminum electrolytic capacitors with identical lead spacing and diameter. The 380LX471M250J042 features significantly lower ESR (39 mOhm @ 120Hz versus 423 mOhm) and extended lifetime (3000 Hrs @ 85°C versus 1000 Hrs @ 85°C). The 380LX series part is 42.00 mm in height versus 35.00 mm, requiring clearance verification.

Q: Is the LAR2E471MELA35 suitable for high-temperature applications?

A: The LAR2E471MELA35 operates across -40 to 105°C, extending 20°C beyond the LPX471M250C5P3 (-40 to 85°C). Lifetime rating is 2000 Hrs @ 105°C, providing thermal performance margin for elevated ambient or self-heating conditions. Electrical parameters (470 µF, 250 V, ±20%) remain equivalent.

Q: Can the 250USG470MEFCSN25X25 be used in space-constrained applications?

A: The 250USG470MEFCSN25X25 (Rubycon USG series) has a height of 27.00 mm, which is 8.00 mm shorter than the LPX471M250C5P3 (35.00 mm). Diameter remains 25.00 mm and lead spacing is 10.00 mm. This part is suitable for applications with vertical space constraints while maintaining electrical equivalence.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—380LX471M250J042, SLPX471M250E1P3, 250USG470MEFCSN25X25, and LAR2E471MELA35—are ROHS3 compliant and Active status, meeting regulatory requirements equivalent to the LPX471M250C5P3.

Q: What does ESR variation mean for circuit performance?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. The 380LX471M250J042 (39 mOhm) has significantly lower ESR than the LPX471M250C5P3 (423 mOhm), resulting in reduced impedance and improved performance in high-ripple-current applications. The SLPX471M250E1P3 maintains identical ESR (423 mOhm) to the original part.

Q: Can mechanical dimensions vary between substitute parts?

A: Yes. While all substitute parts maintain identical lead spacing (10.00 mm) and diameter (25.00 mm) except SLPX471M250E1P3 (30.00 mm diameter), heights vary: LPX471M250C5P3 (35.00 mm), 380LX471M250J042 (42.00 mm), SLPX471M250E1P3 (25.00 mm), 250USG470MEFCSN25X25 (27.00 mm), and LAR2E471MELA35 (35.00 mm). PCB layout must accommodate these variations.
