380LX331M250A202 Equivalent & Substitute Parts

Part Overview

The 380LX331M250A202 is a 330 µF, 250 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, though 896 pieces remain in stock. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 3000 hours at 85°C and an equivalent series resistance (ESR) of 550 mOhm. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for ongoing design support, maintenance, and new production requirements.

Substitute Part Grouping Explanation

Substitution of the 380LX331M250A202 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 250 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can - Snap-In (exact match required)

Allowable Variation Parameters:

ESR: Substitutes may range from 550 mOhm to 603 mOhm without functional impact
Lifetime @ Temperature: Substitutes with 1000 Hrs @ 85°C, 2000 Hrs @ 85°C, 3000 Hrs @ 85°C, or 3000 Hrs @ 105°C are acceptable

Engineering Selection Recommendations

Direct Equivalents (CDE Product Line):

The parts 380LX331M250J022 and 380LX331M250K012 are direct equivalents from the active CDE 380LX series. Both maintain the original 550 mOhm ESR specification and 3000-hour lifetime at 85°C. These parts are recommended as primary substitutes due to identical electrical performance and active product status. Physical dimensions vary slightly (diameter and height), but all maintain the required 10.00 mm lead spacing and snap-in package configuration.

Secondary Equivalents (CDE Alternative Series):

The SLPX series parts (SLPX331M250A3P3 and SLPX331M250C1P3) provide 3000-hour lifetime at 85°C with slightly elevated ESR of 603 mOhm. These parts are suitable for applications where the minor ESR increase does not impact circuit performance. Both are active products with high inventory availability.

Extended Temperature Range Alternatives:

The SLP331M250E1P3 (CDE) and B43254D2337M (EPCOS - TDK Electronics) and LGJ2E331MELC (Nichicon) offer extended operating temperature ranges (-25°C ~ 105°C or -40°C ~ 105°C) with 3000-hour lifetime at 105°C. These upgrades are suitable for applications requiring enhanced thermal performance. B43254D2337M and LGJ2E331MELC maintain identical physical dimensions (35.00 mm diameter, 22.00 mm height) to the original part.

Lower Lifetime Alternatives:

The LPX series parts (LPX331M250A5P3 and LPX331M250C3P3) provide 1000-hour lifetime at 85°C with 603 mOhm ESR. These are suitable only for applications with reduced thermal stress or shorter operational life requirements.

Compliance Status:

All substitute parts listed are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can 380LQ331M250H022 replace 380LX331M250A202 directly?

A: 380LQ331M250H022 meets all critical electrical parameters (330 µF, 250 V, ±20% tolerance, polar, snap-in package, 10.00 mm lead spacing). However, physical dimensions differ: 22.00 mm diameter and 32.00 mm height versus the original 35.00 mm diameter and 22.00 mm height. Verify mechanical fit within the application before substitution.

Q: What is the difference between 550 mOhm and 603 mOhm ESR?

A: ESR affects ripple current handling and heat dissipation. The 603 mOhm ESR in SLPX and LPX series parts results in slightly higher power dissipation under ripple current conditions. For applications with low ripple current or non-critical thermal requirements, this difference is negligible. For high-ripple-current applications, the 550 mOhm ESR parts (380LX331M250J022 or 380LX331M250K012) are preferred.

Q: Are 1000-hour lifetime parts suitable for my application?

A: LPX series parts with 1000-hour lifetime at 85°C are suitable only for applications with limited operational duration or reduced thermal stress. For continuous operation or applications requiring extended service life, select parts with 2000-hour or 3000-hour ratings.

Q: What is the advantage of B43254D2337M or LGJ2E331MELC over CDE alternatives?

A: B43254D2337M (EPCOS - TDK Electronics) and LGJ2E331MELC (Nichicon) offer extended operating temperature range (-40°C ~ 105°C) and 3000-hour lifetime at 105°C, compared to the original part's -40°C ~ 85°C range and 3000-hour lifetime at 85°C. These upgrades provide enhanced thermal performance for high-temperature applications. Both maintain identical physical dimensions (35.00 mm diameter, 22.00 mm height) to the original part.

Q: Does lead spacing remain constant across all substitutes?

A: Yes. All substitute parts maintain 0.394" (10.00 mm) lead spacing, ensuring compatibility with existing PCB layouts and through-hole mounting patterns.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original 380LX331M250A202.

Q: Can I use SLPX331M250C1P3 in a space-constrained application?

A: SLPX331M250C1P3 has the smallest footprint among active substitutes: 25.00 mm diameter and 25.00 mm height. This part is suitable for space-constrained applications while maintaining 3000-hour lifetime at 85°C and 603 mOhm ESR.
