380LX331M200H022

Part Overview

The 380LX331M200H022 is a 330 µF, 200 V aluminum electrolytic capacitor with radial, can snap-in package from Cornell Dubilier Electronics (CDE). This through-hole component operates across -40°C to 85°C with a 3000-hour lifetime rating at 85°C. The product is currently active in the market.

Alternative models become necessary when design requirements change, such as higher voltage ratings for enhanced headroom, extended lifetime requirements for critical applications, lower ESR specifications for improved ripple current handling, or when preferred manufacturer availability is constrained.

Engineering Selection Recommendations

Direct Equivalent - Active Status (Preferred for New Designs): SLPX331M200A1P3 from Cornell Dubilier Electronics provides electrical equivalence with identical capacitance, voltage rating, and tolerance specifications. This part is listed as Active and ROHS3 compliant. The primary design constraint is reduced height (25.00 mm vs. 32.00 mm), which requires board-level clearance verification.

Direct Equivalent - Obsolete Status (Not Recommended for New Designs): SLPX331M200A3P3 matches the 380LX331M200H022 specification but carries an Obsolete product status. This designation indicates limited future availability and supplier support. Selection of this part is not appropriate for designs requiring long-term component sourcing.

Upgrade Options with Higher Voltage Rating (Active Status): SLPX331M220A3P3 and SLPX331M250A3P3 provide voltage ratings of 220 V and 250 V respectively. These parts retain the same capacitance, tolerance, and mechanical footprint as the main part, with identical height (30.00 mm). Both are listed as Active. Higher voltage rating delivers additional design margin and is suitable when the application circuit tolerance permits.

Alternative from Different Manufacturer - EPCOS Series: B43504A2337M000 matches the 200 V rating with identical height. However, this part carries a "Not For New Designs" product status, which restricts its use in new developments. ESR is lower (390 mOhm @ 100 Hz), but frequency testing conditions differ from the main part, making direct comparison of ripple current performance imprecise.

Upgrade Options with Extended Temperature Rating (Active Status): 250MXG330MEFCSN22X30 (Rubycon, MXG series) and LGN2E331MELZ30 (Nichicon, LGN series) offer 250 V rating with extended thermal operation to 105°C. Both are listed as Active and ROHS3 compliant. These upgrades provide enhanced thermal margin suitable for high-reliability applications.

Extended Lifetime Upgrade (Active Status): LGR2D331MELZ30 from Nichicon delivers a 200 V rating matching the main part voltage, but extends lifetime to 10000 hours at 105°C (compared to 3000 hours at 85°C for the original). This part is Active and ROHS3 compliant, appropriate for long-lifecycle applications requiring extended mean time between failures.

Similar Specification - Different Height (Active Status): LLS2D331MELZ from Nichicon provides identical electrical parameters but is limited to 25.00 mm height. Mechanical compatibility requires explicit board layout verification. This part is Active and ROHS3 compliant but the reduced height constrains its application to designs with sufficient vertical clearance.

Frequently Asked Questions (FAQ)

Q: Can I use SLPX331M200A1P3 as a direct replacement for the 380LX331M200H022?

A: SLPX331M200A1P3 is electrically equivalent with matching capacitance (330 µF), voltage rating (200 V), tolerance (±20%), lead spacing (10.00 mm), and diameter (22.00 mm). The critical difference is height: SLPX331M200A1P3 measures 25.00 mm versus 32.00 mm for the original part. Substitution is permissible only if the printed circuit board has adequate clearance above the capacitor location.

Q: Why would I choose a higher voltage rating part like SLPX331M250A3P3?

A: Higher voltage-rated capacitors provide additional design margin without changing capacitance or tolerance. If the circuit supply voltage permits (voltage ratings of 220 V or 250 V are derated versions for use at or below the original 200 V specification), upgrading to a higher-rated device extends component life and improves reliability. The SLPX331M250A3P3 retains the same height (30.00 mm) as the SLPX331M200A3P3, simplifying board design.

Q: What is the difference between a "Direct," "Upgrade," and "Similar" substitute?

A: A Direct substitute maintains identical critical electrical and mechanical parameters, enabling one-to-one replacement without design changes. An Upgrade substitute improves one or more performance characteristics—such as voltage rating or operating temperature range—while maintaining pin compatibility. A Similar substitute matches electrical specifications but differs in mechanical dimensions, requiring board-level compatibility verification before use.

Q: Should I use parts marked as "Obsolete" or "Not For New Designs"?

A: Parts designated Obsolete or Not For New Designs (such as SLPX331M200A3P3 and B43504A2337M000) are not recommended for new product designs. These designations indicate that manufacturers are discontinuing production and limiting support. While such parts may remain available in inventory, future sourcing becomes increasingly difficult. Active-status parts such as SLPX331M200A1P3 or the Nichicon alternatives are preferred for designs with multi-year production windows.

Q: How do I determine if ESR differences matter for my application?

A: Equivalent Series Resistance (ESR) affects ripple current capability and heat dissipation. The main part specifies 600 mOhm @ 120 Hz. Substitute parts with lower ESR (such as B43504A2337M000 at 390 mOhm @ 100 Hz) can handle higher ripple currents with less heating. However, ESR testing frequency varies between manufacturers, so direct numeric comparison across different part series is imprecise without normalized test conditions.

Q: Can I use LLS2D331MELZ in a design with tight vertical space constraints?

A: LLS2D331MELZ measures 25.00 mm in height, matching the reduced height of SLPX331M200A1P3. This part is electrically equivalent to the 380LX331M200H022 and Active in product status. Mechanical compatibility is confirmed for board locations with 25.00 mm maximum clearance. Note that this Nichicon part's ripple current specification is measured at 50 kHz, differing from the main part's 20 kHz reference, making direct ripple current comparison imprecise.

Q: What is the benefit of the LGR2D331MELZ30 with 10000-hour lifetime?

A: LGR2D331MELZ30 extends component lifetime to 10000 hours at 105°C, compared to 3000 hours at 85°C for the main part. This extended lifetime is achieved through superior internal construction. This upgrade is suitable for applications where capacitor replacement is difficult or costly, such as outdoor installations, medical devices, or industrial systems with long service intervals. The 200 V rating matches the original part, and all dimensions are identical.
