Substitute Part Grouping Explanation

Substitution of the LPW682M1EP25V-W is determined by the following critical parameters:

Electrical Compatibility Requirements:

Capacitance value: 6800 µF (fixed)
Tolerance: ±20% (fixed)
Voltage rating: 25 V minimum (equal or higher voltage ratings are acceptable)
Polarization: Polar (required)

Mechanical Compatibility Requirements:

Lead spacing: 0.394" (10.00 mm) (fixed for PCB layout)
Package type: Radial, Can - Snap-In (required for mounting compatibility)
Mounting type: Through Hole (required)

Performance Considerations:

ESR, ripple current, and lifetime ratings may vary between substitutes
Operating temperature range must encompass application requirements
All substitutes must maintain ROHS3 compliance and REACH unaffected status

Substitute parts are grouped into two categories:

Direct Substitutes (Voltage Upgrade): Parts with 35 V rating that maintain identical mechanical dimensions and lead spacing, providing enhanced voltage margin and improved electrical performance.

Equivalent Substitutes (Same Voltage): Parts with 25 V rating that maintain identical electrical specifications but may have different physical dimensions or performance characteristics.

Engineering Selection Recommendations

Primary Recommendation: SLPX682M035E1P3

The SLPX682M035E1P3 is the preferred direct substitute for the obsolete LPW682M1EP25V-W. This part maintains identical mechanical dimensions (1.181" diameter, 0.984" height, 0.394" lead spacing) and package configuration, ensuring direct PCB compatibility without layout modifications. The 35 V rating provides voltage margin above the original 25 V specification. ESR is reduced from 110 mOhm to 78 mOhm, improving ripple current performance. Lifetime is extended from 1000 hours to 3000 hours at 85°C. The part is active in production and ROHS3 compliant.

Secondary Recommendation: SLP682M035E1P3

The SLP682M035E1P3 offers identical mechanical compatibility to SLPX682M035E1P3 with extended operating temperature range (-40°C to 105°C) and improved thermal lifetime (3000 hours at 105°C). This part is suitable for applications requiring enhanced thermal performance. All other electrical and mechanical parameters remain equivalent to SLPX682M035E1P3.

Equivalent Alternatives (Same Voltage Rating):

For applications requiring strict 25 V voltage rating maintenance, the following active parts provide equivalent electrical specifications with alternative physical dimensions:

380LX682M025K202: Maintains original 1.181" diameter but reduces height to 0.866", offering space savings in vertical direction.
380LX682M025J012: Provides intermediate dimensions (0.984" diameter, 1.063" height) with higher ripple current capability (3.5 A @ 120 Hz).
380LX682M025H022: Reduces diameter to 0.866" but increases height to 1.260", suitable for space-constrained horizontal layouts.
SLPX682M025A3P3: Offers compact dimensions (0.866" diameter, 1.181" height) with active product status.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and through-hole radial snap-in package configuration.

Frequently Asked Questions (FAQ)

Q: Can SLPX682M035E1P3 be used as a direct replacement for LPW682M1EP25V-W without PCB modifications?

A: Yes. SLPX682M035E1P3 maintains identical lead spacing (0.394" / 10.00 mm), package type (radial snap-in), and physical dimensions (1.181" diameter, 0.984" height). No PCB layout changes are required. The higher voltage rating (35 V vs. 25 V) is electrically compatible with 25 V circuit designs.

Q: What is the difference between SLPX682M035E1P3 and SLP682M035E1P3?

A: Both parts share identical mechanical dimensions and 35 V voltage rating. The primary difference is operating temperature range: SLPX682M035E1P3 operates -40°C to 85°C with 3000 hours lifetime at 85°C, while SLP682M035E1P3 operates -40°C to 105°C with 3000 hours lifetime at 105°C. Select SLP682M035E1P3 for applications requiring extended thermal performance.

Q: Why do the 380LX series parts have different physical dimensions?

A: The 380LX series maintains the same electrical specifications (6800 µF, 25 V, ±20%) and lead spacing (0.394") but offers multiple form factors to accommodate different PCB space constraints. Each variant (H022, J012, K202) provides different diameter and height combinations. Verify PCB clearance before selection.

Q: Is the reduced ESR in substitute parts beneficial?

A: Yes. Lower ESR (78-88 mOhm vs. 110 mOhm) reduces heat generation and improves ripple current handling. This represents improved performance compared to the original LPW682M1EP25V-W specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original part.

Q: Can I use 380LX682M025H022 if my PCB has limited vertical space?

A: 380LX682M025H022 has a reduced diameter (0.866" vs. 1.181") but increased height (1.260" vs. 0.984"). This part is suitable only if vertical space is available and horizontal space is constrained. Verify PCB clearance in both dimensions before selection.

Q: What is the impact of using a 25 V rated part in a 25 V circuit versus a 35 V rated part?

A: Both are electrically compatible. The 35 V rated parts (SLPX682M035E1P3, SLP682M035E1P3) provide voltage margin and typically exhibit lower ESR and longer lifetime. Use 35 V parts when available space permits. Use 25 V parts only when voltage rating is a specific design constraint.
