Substitute Part Grouping Explanation

Substitution eligibility for the LPX102M250E4P3 is determined by strict equivalence in the following parameters: capacitance (1000 µF), voltage rating (250 V), tolerance (±20%), package type (Radial, Can - Snap-In), mounting type (Through Hole), lead spacing (0.394" / 10.00mm), operating temperature range (-40°C to 85°C), and polarization (Polar). All identified substitute parts meet these core electrical and mechanical requirements.

Substitute parts are grouped into three categories based on their relationship to the main part:

Upgrade Parts offer extended lifetime at 85°C (3000 hours versus 1000 hours) while maintaining or improving electrical characteristics. These parts are direct functional upgrades suitable for applications requiring enhanced reliability.

Direct Equivalents provide identical or equivalent electrical performance with different manufacturer sourcing, enabling supply chain flexibility.

Similar Parts maintain core electrical specifications but may exhibit variations in physical dimensions (diameter or height) or ESR characteristics. These parts are compatible within the same application space but require verification of mechanical fit within the assembly.

Engineering Selection Recommendations

For Direct Replacement with Extended Reliability: The 380LX102M250K452 (CDE, 380LX series) and SLPX102M250E5P3 (CDE, SLPX series) are upgrade substitutes offering 3000-hour lifetime ratings at 85°C compared to the 1000-hour rating of the LPX102M250E4P3. Both parts maintain ROHS3 compliance and identical electrical specifications. The 380LX102M250K452 exhibits lower ESR (182 mOhm) and is available in higher inventory quantities (8636 units). The SLPX102M250E5P3 provides a more compact form factor with reduced height (1.378" versus 1.772"), beneficial for space-constrained applications.

For Cross-Manufacturer Sourcing: The LLS2E102MELB (Nichicon, LLS series) provides a direct equivalent from an alternative manufacturer with 3000-hour lifetime and ROHS3 compliance. This part offers the highest ripple current capability at 120 Hz (3.56 A) and is available in substantial inventory (274,082 units). ESR data is not specified for this part.

For Extended Operational Lifetime: The ALC10A102DF250 (KEMET, ALC10 series) delivers the longest operational lifetime at 15,000 hours at 85°C with the lowest ESR specification (163 mOhm @ 100Hz). This part is suitable for applications requiring maximum reliability over extended service periods. Physical dimensions differ significantly (1.378" diameter, 2.047" height), requiring verification of mechanical fit within the assembly.

For Space-Constrained Applications: The SLPX102M250E5P3 offers the most compact profile with a height of 1.378" while maintaining upgrade performance characteristics.

All substitute parts maintain the required 0.394" (10.00mm) lead spacing and through-hole mounting compatibility with the original LPX102M250E4P3 design.

Frequently Asked Questions (FAQ)

Q: Can the 380LX102M250K452 be used as a direct replacement for the LPX102M250E4P3?

A: Yes. Both parts share identical capacitance (1000 µF), voltage rating (250 V), tolerance (±20%), lead spacing (10.00mm), and operating temperature range (-40°C to 85°C). The 380LX102M250K452 provides improved ESR (182 mOhm versus 199 mOhm) and extended lifetime (3000 hours versus 1000 hours at 85°C). Physical height differs by 0.078" (2.00mm), which must be verified for fit within the assembly.

Q: What is the primary difference between the SLPX102M250E5P3 and the 380LX102M250K452?

A: Both are CDE upgrade parts with 3000-hour lifetime ratings. The SLPX102M250E5P3 features a more compact height (1.378" versus 1.850") and maintains identical ESR (199 mOhm) to the original part. The 380LX102M250K452 offers lower ESR (182 mOhm) but requires additional vertical clearance.

Q: Is the LLS2E102MELB from Nichicon compatible with the LPX102M250E4P3?

A: Yes. The LLS2E102MELB meets all core electrical and mechanical requirements: 1000 µF capacitance, 250 V rating, ±20% tolerance, 10.00mm lead spacing, and through-hole mounting. It provides 3000-hour lifetime and ROHS3 compliance. ESR is not specified for this part. Height is 1.575" (40.00mm), requiring verification of fit.

Q: Why does the ALC10A102DF250 have different physical dimensions?

A: The ALC10A102DF250 is designed for extended operational lifetime (15,000 hours at 85°C) and lower ESR (163 mOhm). These performance enhancements require a larger physical package: 1.378" diameter and 2.047" height. Mechanical fit verification is required before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance status, consistent with the original LPX102M250E4P3.

Q: What is the significance of the 0.394" (10.00mm) lead spacing?

A: Lead spacing determines PCB hole pattern compatibility. All substitute parts maintain this specification, ensuring direct mechanical compatibility with existing through-hole mounting patterns designed for the LPX102M250E4P3.

Q: Can the 380LQ102M250A022 be used as a substitute?

A: The 380LQ102M250A022 meets core electrical specifications but exhibits different physical dimensions (1.378" diameter, 1.260" height) compared to the LPX102M250E4P3 (1.181" diameter, 1.772" height). Mechanical fit verification is required. Lifetime is 2000 hours at 85°C, providing intermediate reliability between the original part and extended-life upgrades.
