Engineering Selection Recommendations

SLP682M063E9P3 (Upgrade Substitute): This part is suitable for applications requiring enhanced reliability and extended operational life. The 63 V rating provides a 26% voltage margin above the 50 V requirement, and the 3000-hour lifetime at 105°C represents a 3× improvement over the main part. The identical physical footprint (30.00 mm diameter, 50.00 mm height) and lead spacing (10.00 mm) ensure direct mechanical compatibility. All regulatory certifications (ROHS3 Compliant, REACH Unaffected) match the main part. Selection of this upgrade is appropriate when thermal stress or extended service intervals are design considerations.

381LX682M050A022 (Similar Substitute): This part maintains identical electrical specifications (6800 µF, 50 V, ±20% tolerance) and offers extended 3000-hour lifetime at 105°C. The physical dimensions differ: 35.00 mm diameter and 32.00 mm height versus the main part's 30.00 mm diameter and 50.00 mm height. Lead spacing remains compatible at 10.00 mm. This substitute is applicable in designs where the reduced height (32.00 mm versus 50.00 mm) provides space optimization benefits, provided the increased diameter (35.00 mm versus 30.00 mm) does not create layout constraints. ROHS3 and REACH compliance are maintained.

LGU1H682MELB (Direct Substitute): This Nichicon part provides cross-manufacturer equivalence with identical electrical specifications (6800 µF, 50 V, ±20% tolerance) and extended 3000-hour lifetime at 105°C. Physical dimensions closely match the main part: 30.00 mm diameter and 37.00 mm height, with identical 10.00 mm lead spacing. This substitute enables supplier diversification while maintaining functional and mechanical compatibility. ROHS3 compliance and REACH Unaffected status are confirmed. The Moisture Sensitivity Level is listed as Not Applicable for this part.

All substitute parts maintain the required through-hole mounting configuration, radial snap-in package type, and operating temperature range of -40°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Can SLP682M063E9P3 be used as a direct replacement for LP682M050E9P3?

A: Yes. The SLP682M063E9P3 is mechanically and electrically compatible. The 63 V rating exceeds the 50 V requirement, and the identical physical dimensions (30.00 mm diameter, 50.00 mm height) and lead spacing (10.00 mm) ensure direct board-level compatibility. The higher voltage rating does not create functional issues in 50 V applications.

Q: What are the physical dimension differences between substitute parts?

A: The main part LP682M050E9P3 has a diameter of 30.00 mm and height of 50.00 mm. The SLP682M063E9P3 upgrade maintains these exact dimensions. The 381LX682M050A022 has a larger diameter (35.00 mm) but reduced height (32.00 mm). The LGU1H682MELB has the same 30.00 mm diameter but intermediate height (37.00 mm). All maintain the 10.00 mm lead spacing.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—SLP682M063E9P3, 381LX682M050A022, and LGU1H682MELB—are ROHS3 Compliant and REACH Unaffected, matching the regulatory status of the main part LP682M050E9P3.

Q: What is the lifetime advantage of substitute parts?

A: The main part LP682M050E9P3 has a rated lifetime of 1000 hours at 105°C. All three substitute parts offer 3000 hours at 105°C, representing a 3× improvement in thermal endurance. This extended lifetime is particularly relevant for applications with sustained elevated temperature operation.

Q: Can 381LX682M050A022 be used if space is constrained vertically?

A: Yes, if vertical space is the limiting factor. The 381LX682M050A022 has a height of 32.00 mm compared to the main part's 50.00 mm, providing 18.00 mm of vertical clearance. However, the diameter increases from 30.00 mm to 35.00 mm, so horizontal space must be verified. Lead spacing remains compatible at 10.00 mm.

Q: Is LGU1H682MELB suitable for applications requiring supplier diversification?

A: Yes. The LGU1H682MELB is manufactured by Nichicon and provides cross-manufacturer equivalence. Electrical specifications (6800 µF, 50 V, ±20% tolerance) and mechanical compatibility (30.00 mm diameter, 10.00 mm lead spacing) are maintained. The 3000-hour lifetime at 105°C also exceeds the main part's 1000-hour rating.

Q: What is the ESR difference between the main part and substitutes?

A: The main part LP682M050E9P3 specifies 49 mOhm ESR at 120 Hz. The SLP682M063E9P3 upgrade specifies 59 mOhm at 120 Hz. The 381LX682M050A022 and LGU1H682MELB do not provide ESR specifications in the available data. ESR values should be confirmed with manufacturers if low-impedance performance is critical to the application.

Q: Are all parts suitable for general-purpose applications?

A: Yes. All parts—LP682M050E9P3, SLP682M063E9P3, 381LX682M050A022, and LGU1H682MELB—are rated for general-purpose applications and operate across the -40°C to 105°C temperature range.
