380LX331M200J012 Equivalent & Substitute Parts Reference

Part Overview

The 380LX331M200J012 is a 330 µF, 200 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the 380LX series. This radial, can-type snap-in capacitor is designed for general-purpose applications requiring through-hole mounting with a 10.00 mm lead spacing and 25.00 mm diameter form factor. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching or exceeding the core electrical specifications: 330 µF capacitance, ±20% tolerance, 200 V or higher rated voltage, radial snap-in package configuration, and through-hole mounting compatibility. Substitutes are necessary when the original part is unavailable, when extended operating temperature ranges or longer lifetime ratings are required, or when upgraded voltage ratings provide additional design margin.

Engineering Selection Recommendations

Primary Upgrade Path: 381LX331M200J012

The 381LX331M200J012 is the direct upgrade substitute for the 380LX331M200J012. Both parts are manufactured by CDE, maintain identical capacitance, tolerance, voltage rating, and physical dimensions (25.00 mm diameter, 27.00 mm height, 10.00 mm lead spacing). The 381LX series extends the operating temperature range to 105°C and maintains the 3000-hour lifetime rating at this elevated temperature, compared to the 380LX series rating of 3000 hours at 85°C. Both parts are ROHS3 compliant and active in production. This substitute is suitable for applications requiring extended thermal performance without physical redesign.

Voltage-Upgraded Path: SLPX331M250C1P3

The SLPX331M250C1P3 provides a 250 V rated voltage upgrade while maintaining the same 330 µF capacitance and ±20% tolerance. Physical dimensions remain compatible (25.00 mm diameter, 10.00 mm lead spacing), though the seated height is reduced to 25.00 mm. This part is active in production and ROHS3 compliant. The higher voltage rating provides additional design margin for applications subject to voltage transients or overvoltage conditions. The ESR increases to 603 mOhm at 120 Hz compared to the original 470 mOhm.

Extended Lifetime Path: LGR2D331MELA25

The LGR2D331MELA25 (Nichicon LGR series) maintains the 200 V voltage rating and 330 µF capacitance while extending the lifetime to 10000 hours at 105°C, compared to the original 3000 hours at 85°C. Physical dimensions are identical (25.00 mm diameter, 27.00 mm height, 10.00 mm lead spacing). This part is active in production and ROHS3 compliant. Selection of this substitute is appropriate for long-life applications or equipment with extended service intervals.

Alternative Voltage-Upgraded Path: LGN2E331MELA25

The LGN2E331MELA25 (Nichicon LGN series) upgrades both the voltage rating to 250 V and the operating temperature to 105°C with a 3000-hour lifetime at this temperature. Physical dimensions match the original part (25.00 mm diameter, 27.00 mm height, 10.00 mm lead spacing). This part is active in production and ROHS3 Compliant. This substitute combines voltage margin with thermal performance enhancement.

Space-Constrained Alternatives: SLPX331M200A1P3

The SLPX331M200A1P3 maintains electrical specifications identical to the original part (330 µF, 200 V, ±20% tolerance, 3000 hours @ 85°C) but reduces the can diameter to 22.00 mm while maintaining the 10.00 mm lead spacing and 25.00 mm seated height. This part is active in production and ROHS3 compliant. Selection is appropriate for applications with space constraints that do not require extended temperature performance.

Obsolete Status: SLPX331M200A3P3

The SLPX331M200A3P3 is marked as obsolete and should not be selected for new designs. Although it maintains electrical compatibility (330 µF, 200 V, ±20% tolerance, 3000 hours @ 85°C) and physical lead spacing (10.00 mm), the obsolete status indicates discontinued production. The seated height of 30.00 mm also exceeds the original part's 27.00 mm dimension.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 381LX331M200J012 for the 380LX331M200J012 without circuit redesign?

A: Yes. The 381LX331M200J012 is a direct physical and electrical substitute. Both parts share identical capacitance (330 µF), tolerance (±20%), voltage rating (200 V), lead spacing (10.00 mm), diameter (25.00 mm), and seated height (27.00 mm). The 381LX series provides extended operating temperature capability (to 105°C) and is fully compatible with existing PCB layouts and through-hole mounting patterns.

Q: What is the difference between the 380LX and 381LX series?

A: The primary difference is the maximum operating temperature and corresponding lifetime rating. The 380LX series is rated for 3000 hours at 85°C with an operating range of -40°C to 85°C. The 381LX series extends the operating range to -40°C to 105°C and maintains a 3000-hour lifetime at this elevated temperature. Both series share identical electrical specifications and physical form factors.

Q: Can I use SLPX331M250C1P3 in place of 380LX331M200J012?

A: Yes, with the following considerations. The SLPX331M250C1P3 maintains the same capacitance (330 µF), tolerance (±20%), lead spacing (10.00 mm), and diameter (25.00 mm). The voltage rating is upgraded to 250 V, providing additional design margin. The seated height is reduced to 25.00 mm (compared to 27.00 mm for the original part), which may affect PCB layout if height clearance is critical. The ESR increases to 603 mOhm at 120 Hz compared to the original 470 mOhm. This substitute is suitable for applications where the higher voltage rating and reduced height are acceptable.

Q: Why do the Nichicon parts (LGN2E331MELA25 and LGR2D331MELA25) show no ESR value?

A: ESR data is not provided in the specifications for these Nichicon parts. When ESR is not specified, the part should be evaluated based on other performance parameters such as ripple current ratings, lifetime, and operating temperature range. Both Nichicon parts provide extended operating temperature (105°C) and extended or equivalent lifetime ratings compared to the original CDE part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (381LX331M200J012, SLPX331M250C1P3, SLPX331M200A1P3, SLPX331M200A3P3, LGN2E331MELA25, and LGR2D331MELA25) are ROHS3 compliant. The original part 380LX331M200J012 is also ROHS3 compliant.

Q: What is the significance of the SLPX331M200A3P3 being marked as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part. Although the part may still be available from inventory, it should not be selected for new designs or long-term production applications. The 381LX331M200J012 or SLPX331M200A1P3 are recommended as active alternatives.

Q: Can I use a 22.00 mm diameter part (SLPX331M200A1P3) in a PCB designed for a 25.00 mm diameter part?

A: Yes, from a functional and electrical standpoint. The 22.00 mm diameter is smaller and will fit within the space allocated for a 25.00 mm diameter part. However, the mechanical fit may be looser, and the part may not be as mechanically stable in the mounting hole. PCB layout review is recommended to ensure adequate mechanical support and alignment.

Q: What is the ripple current rating, and why does it vary among substitutes?

A: Ripple current rating specifies the maximum AC current the capacitor can safely handle at specified frequencies (typically 120 Hz for low-frequency and 20 kHz for high-frequency applications). Ripple current varies among substitutes due to differences in internal construction, ESR, and thermal design. The original 380LX331M200J012 supports 1.7 A at 120 Hz and 2.4 A at 20 kHz. Substitutes should be selected to meet or exceed the ripple current requirements of the application.

Q: Which substitute offers the longest operational lifetime?

A: The LGR2D331MELA25 (Nichicon) offers the longest lifetime rating at 10000 hours at 105°C, compared to 3000 hours at 85°C for the original part. This extended lifetime is suitable for applications requiring high reliability over extended service periods or for equipment with infrequent maintenance intervals.
