Engineering Selection Recommendations

Direct Replacement Priority: 381LX682M063K052 and LGU1J682MELB are the primary direct replacements, maintaining identical mechanical dimensions (1.181" diameter, 2.047" height) and electrical specifications. Both are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Enhanced Lifetime Option: LGY1J682MELB50 provides extended operational life at 5000 hours versus the original 3000 hours at 105°C, with identical mechanical footprint and ROHS3 compliance. This part is suitable for applications requiring extended service intervals.

Compact Alternatives: SLP682M063E9P3 offers reduced height (1.969" versus 2.047") while maintaining the 30 mm diameter and 3000-hour lifetime specification. This variant accommodates space-constrained designs without electrical performance compromise.

Dimensional Variants: LP682M063H9P3 and SLP682M063H7P3 feature increased case diameter (1.378" versus 1.181") with reduced heights. These parts are suitable only for applications where the larger diameter is accommodated by the PCB layout.

Compliance Consideration: All active substitute parts carry ROHS3 compliance and REACH unaffected status, eliminating regulatory risk associated with the obsolete ECO-S1JA682DA.

Frequently Asked Questions (FAQ)

Q: Can LP682M063H9P3 or SLP682M063H7P3 be used as direct drop-in replacements?

A: No. These parts feature a 1.378" case diameter compared to the original 1.181" diameter. PCB layout must accommodate the larger diameter. Lead spacing remains 0.394" (10.00 mm), but the increased case size may conflict with adjacent components or board routing.

Q: What is the difference between 381LX682M063K052 and LGU1J682MELB?

A: Both parts maintain identical mechanical dimensions and electrical specifications. 381LX682M063K052 is manufactured by Cornell Dubilier Electronics, while LGU1J682MELB is manufactured by Nichicon. Selection depends on supply chain availability and preferred supplier qualification.

Q: Why does B41252A8688M have a shorter lifetime specification?

A: B41252A8688M is rated for 2000 hours at 105°C versus the original 3000 hours. This part is suitable only for applications where the reduced lifetime does not impact system reliability requirements. Verify thermal cycling and operational duty cycle compatibility before selection.

Q: Is ESR variation significant between substitute parts?

A: ESR values range from 37 mOhm to 73.14 mOhm across the substitute parts. Lower ESR reduces heat generation and improves ripple current handling. For applications sensitive to ESR performance, SLP682M063E9P3 (59 mOhm) or LP682M063H9P3 (37 mOhm) are preferred over 688LMB063M2DH (73.14 mOhm).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts carry ROHS3 compliance certification. The original ECO-S1JA682DA is REACH affected; all substitutes are REACH unaffected, eliminating regulatory compliance risk.

Q: What is the lead spacing tolerance for through-hole mounting?

A: All parts maintain 0.394" (10.00 mm) lead spacing. This dimension is fixed and does not vary across the substitute parts, ensuring PCB footprint compatibility for standard through-hole mounting.
