Electrical Equivalence Requirements:

• Capacitance: 470 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 10.00 mm (exact match required)

Operational Compatibility:

• Operating Temperature Range: Must encompass or equal -40°C ~ 85°C minimum
• Applications: General Purpose (exact match required)

Compliance Requirements:

Substitute parts may vary in ESR, ripple current ratings, lifetime at temperature, and physical dimensions (diameter and height) provided all critical parameters above are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed meet the core electrical and mechanical compatibility requirements for the LPX471M250E3P3. Selection among substitutes is based on the following engineering considerations:

SLPX471M250E1P3 (CDE): This upgrade substitute maintains identical electrical specifications (470 µF, 250 V, ±20%, 423 mOhm ESR) while extending lifetime to 3000 Hrs @ 85°C. Height is reduced to 25.00 mm, providing a more compact form factor. ROHS3 compliant and REACH unaffected. Suitable for applications requiring extended operational life within standard thermal parameters.

380LX471M250J042 (CDE): This substitute offers significantly reduced ESR (39 mOhm vs. 423 mOhm), beneficial for high-ripple-current applications. Lifetime extends to 3000 Hrs @ 85°C. Physical dimensions differ: 25.00 mm diameter and 42.00 mm height. ROHS3 compliant and REACH unaffected. Suitable for applications where low impedance is critical.

250USG470MEFCSN25X25 (Rubycon): This direct substitute maintains 470 µF, 250 V, ±20% specifications with 3000 Hrs @ 85°C lifetime. Dimensions are 25.00 mm diameter and 27.00 mm height. ROHS3 compliant and REACH unaffected. Suitable for space-constrained applications requiring extended life.

LGU2E471MELB (Nichicon): This upgrade substitute extends operating temperature range to -40°C ~ 105°C and provides 3000 Hrs @ 105°C lifetime. Maintains 30.00 mm diameter and height matching the original part. ROHS3 compliant and REACH unaffected. Suitable for applications requiring enhanced thermal performance and extended operational life at elevated temperatures.

Frequently Asked Questions (FAQ)

Q: Can SLPX471M250E1P3 be used as a direct replacement for LPX471M250E3P3?

A: Yes. SLPX471M250E1P3 meets all critical electrical and mechanical compatibility requirements. It maintains identical capacitance (470 µF), voltage rating (250 V), tolerance (±20%), and ESR (423 mOhm @ 120Hz). Lead spacing (10.00 mm) and mounting type (through-hole, radial snap-in) are identical. The primary difference is extended lifetime (3000 Hrs @ 85°C vs. 1000 Hrs @ 85°C) and reduced height (25.00 mm vs. 30.00 mm). Both are ROHS3 compliant and REACH unaffected.

Q: What is the significance of ESR differences between substitute parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. The LPX471M250E3P3 and SLPX471M250E1P3 both specify 423 mOhm @ 120Hz. The 380LX471M250J042 specifies 39 mOhm, which is substantially lower. Lower ESR reduces impedance and improves performance in high-ripple-current applications. Selection depends on application-specific ripple current requirements.

Q: Are physical dimension differences critical for substitution?

A: Physical dimensions must be verified against PCB layout and mechanical constraints. The LPX471M250E3P3 is 30.00 mm diameter × 30.00 mm height. Substitutes vary: SLPX471M250E1P3 (30.00 mm × 25.00 mm), 380LX471M250J042 (25.00 mm × 42.00 mm), 250USG470MEFCSN25X25 (25.00 mm × 27.00 mm), and LGU2E471MELB (30.00 mm × 30.00 mm). Lead spacing remains constant at 10.00 mm across all parts. Verify clearance and mounting space before selection.

Q: Why would LGU2E471MELB be selected over other substitutes?

A: LGU2E471MELB is selected when applications require extended thermal performance. It operates across -40°C ~ 105°C (vs. -40°C ~ 85°C for other parts) and provides 3000 Hrs @ 105°C lifetime. Physical dimensions (30.00 mm × 30.00 mm) match the original part exactly. This substitute is suitable for high-temperature environments or applications requiring enhanced reliability margins at elevated operating temperatures.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are ROHS3 compliant and REACH unaffected, matching the original LPX471M250E3P3. All parts carry Active product status. ECCN classification is EAR99 and HTSUS code is 8532.22.0040 across all parts. Moisture Sensitivity Level (MSL) varies: LPX471M250E3P3 and 380LX471M250J042 are MSL 1 (Unlimited); SLPX471M250E1P3, 250USG470MEFCSN25X25, and LGU2E471MELB are Not Applicable.

Q: Can 380LX471M250J042 be used in applications with strict height constraints?

A: No. The 380LX471M250J042 has a seated height of 42.00 mm, which exceeds the original part's 30.00 mm height. This part is suitable only for applications with adequate vertical clearance. For height-constrained applications, SLPX471M250E1P3 (25.00 mm height) or 250USG470MEFCSN25X25 (27.00 mm height) are more appropriate selections.

Q: Are all substitute parts available in the same packaging as the original?

A: The original LPX471M250E3P3 is packaged as individual units. Substitute parts are available in Bulk packaging: SLPX471M250E1P3, 380LX471M250J042, 250USG470MEFCSN25X25, and LGU2E471MELB. Verify packaging requirements and order quantities with supplier specifications before procurement.
