Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Substitutes):

LGU1H682MELA (Nichicon) and SLP682M050C4P3 (Cornell Dubilier Electronics) are direct functional equivalents meeting all electrical and mechanical parameters. Both are active products with ROHS3 compliance. LGU1H682MELA offers a reduced height profile (1.850" vs. 2.047"), which may provide layout advantages in space-constrained applications. SLP682M050C4P3 maintains similar dimensional characteristics to the original part while offering active product status and full compliance certifications.

Voltage-Upgraded Alternative:

381LX682M063J052 (Cornell Dubilier Electronics) provides a 63 V rating while maintaining identical physical dimensions and 6800 µF capacitance. This upgrade is suitable for applications requiring enhanced voltage margin and is ROHS3 compliant with active product status.

Dimensional Variants:

381LX682M050A022, 381LX682M050K042, SLP682M050E5P3, MAL215831682E3, LP682M050E7P3, and LP682M050E9P3 maintain electrical equivalence (6800 µF, 50 V, ±20%) but feature different physical dimensions. These are suitable for applications where board layout constraints permit dimensional variation. All are active products with ROHS3 compliance.

Limited Substitution:

B41252B6568M (EPCOS - TDK Electronics) has reduced capacitance (5600 µF) and lifetime rating (2000 hours), making it unsuitable as a direct substitute. This part is listed only for reference in applications where reduced capacitance is acceptable.

Reduced Lifetime Consideration:

LP682M050E7P3 and LP682M050E9P3 feature 1000-hour lifetime ratings at 105°C, compared to the original 3000-hour specification. These parts are suitable only for applications with lower reliability requirements or shorter operational lifespans.

Frequently Asked Questions (FAQ)

Q: Can I use a 63 V rated capacitor in place of a 50 V rated capacitor?

A: Yes. The 381LX682M063J052 (63 V) is a valid upgrade substitute. Higher voltage ratings provide increased safety margin and are electrically compatible with 50 V circuit designs. No circuit modification is required.

Q: Are there dimensional constraints I should consider when selecting a substitute?

A: Yes. While all listed substitutes maintain the 0.394" (10.00 mm) lead spacing required for snap-in mounting, physical diameter and height vary. Verify that the selected substitute fits within your PCB layout and mechanical enclosure constraints. The original part measures 0.984" diameter × 2.047" height; alternatives range from 0.984" to 1.378" diameter and 1.260" to 2.047" height.

Q: What is the difference between direct equivalents and similar parts?

A: Direct equivalents (LGU1H682MELA, SLP682M050C4P3) match all electrical specifications and maintain similar physical dimensions. Similar parts meet electrical requirements but may have different dimensions, ESR characteristics, or lifetime ratings. Selection depends on your specific application requirements and available board space.

Q: Does ESR variation affect circuit performance?

A: ESR differences are provided for reference. The original part specifies 46 mOhm @ 120Hz. Substitutes range from 49 mOhm to 68 mOhm. For most general-purpose applications, these variations are within acceptable tolerance. Applications with strict ripple current or thermal dissipation requirements should verify ESR specifications against circuit design parameters.

Q: Are all active substitutes RoHS3 compliant?

A: All active product substitutes listed are ROHS3 compliant except where noted. Verify compliance requirements for your specific application and region before final part selection.

Q: What is the significance of lifetime ratings at 105°C?

A: Lifetime rating indicates expected operational hours at maximum temperature. The original part specifies 3000 hours. Substitutes with equal or greater lifetime ratings (MAL215831682E3 at 5000 hours) provide equivalent or improved reliability. Parts with reduced lifetime (LP series at 1000 hours) are suitable only for applications with lower reliability requirements.
