338LBA050M2BD Equivalent & Substitute Parts Reference

Part Overview

The 338LBA050M2BD is a 3300 µF, 50 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the LBA series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high capacitance in a compact through-hole package. The part is Active status and RoHS3 compliant.

Substitute parts are necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when application requirements permit selection from qualified equivalent or upgraded alternatives. The substitute parts listed maintain the core electrical specifications (capacitance, voltage rating, tolerance) while offering variations in ESR, lifetime ratings, and thermal performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 338LBA050M2BD is determined by strict adherence to the following parameters:

Core Electrical Requirements (Non-Negotiable):

• Capacitance: 3300 µF
• Voltage Rating: 50 V
• Tolerance: ±20%
• Polarization: Polar

Mechanical Requirements (Non-Negotiable):

• Package Type: Radial, Can - Snap-In
• Mounting Type: Through Hole
• Lead Spacing: 0.394" (10.00mm)
• Diameter: 0.866" (22.00mm)

Performance Parameters (Variable - Allows Substitution):

• ESR (Equivalent Series Resistance): May vary
• Lifetime @ Temperature: May vary
• Operating Temperature Maximum: May extend to 105°C
• Height - Seated: May vary within mechanical compatibility
• Ripple Current Ratings: May vary

All four substitute parts meet the core electrical and mechanical requirements. Variations in ESR, lifetime ratings, and maximum operating temperature represent performance enhancements or alternative specifications within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Performance):

The 380LX332M050H022 and SLPX332M050A3P3 are direct substitutes for the 338LBA050M2BD. Both parts are manufactured by Cornell Dubilier Electronics and maintain identical core specifications. The 380LX332M050H022 offers improved ESR performance (100 mOhm versus 175.83 mOhm) and extended lifetime (3000 Hrs @ 85°C versus 2000 Hrs @ 85°C). The SLPX332M050A3P3 provides moderate ESR improvement (141 mOhm) with equivalent lifetime extension and a slightly reduced seated height (1.181" versus 1.260"), which may provide additional PCB layout flexibility.

Upgrade Substitute (Enhanced Thermal Performance):

The MAL225621332E3 manufactured by Vishay Beyschlag/Draloric/BC Components is classified as an upgrade substitute. This part extends the maximum operating temperature to 105°C while maintaining the 2000 Hrs lifetime rating at the elevated temperature. This part is suitable for applications requiring enhanced thermal margin. The seated height remains at 1.260", matching the main part specification.

Parametric Equivalent (Alternative Source):

The B41231A6338M000 manufactured by EPCOS - TDK Electronics is a parametric equivalent from an alternative manufacturer. This part maintains all core electrical and mechanical specifications. ESR is not specified in the provided data. This part is suitable for applications where multi-source qualification is required or when primary suppliers are unavailable.

All substitute parts are Active status and comply with RoHS3 requirements where specified. Selection should be based on application requirements for ESR performance, thermal operating range, and lifetime rating at operating temperature.

Frequently Asked Questions (FAQ)

Q: Can the 380LX332M050H022 be used as a direct replacement for the 338LBA050M2BD?

A: Yes. The 380LX332M050H022 meets all core electrical specifications (3300 µF, 50 V, ±20% tolerance) and mechanical requirements (radial snap-in package, 10mm lead spacing, 22mm diameter, through-hole mounting). The part offers improved ESR (100 mOhm versus 175.83 mOhm) and extended lifetime (3000 Hrs @ 85°C versus 2000 Hrs @ 85°C), making it a direct substitute with performance enhancement.

Q: What is the difference between the SLPX332M050A3P3 and the 380LX332M050H022?

A: Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical specifications. The primary differences are: ESR (141 mOhm for SLPX versus 100 mOhm for 380LX) and seated height (1.181" for SLPX versus 1.260" for 380LX). The SLPX offers a lower profile option while maintaining equivalent lifetime performance (3000 Hrs @ 85°C).

Q: Is the MAL225621332E3 compatible with the original 338LBA050M2BD footprint?

A: Yes. The MAL225621332E3 maintains identical lead spacing (10mm), diameter (22mm), and seated height (1.260"), ensuring full mechanical compatibility. The part is suitable for applications requiring extended operating temperature capability up to 105°C.

Q: Can I use the B41231A6338M000 if ESR specification is critical to my application?

A: The B41231A6338M000 ESR value is not specified in the provided technical data. If ESR performance is a critical design parameter, the 380LX332M050H022 (100 mOhm) or SLPX332M050A3P3 (141 mOhm) are recommended alternatives with documented ESR specifications.

Q: Are all substitute parts RoHS3 compliant?

A: The 338LBA050M2BD, 380LX332M050H022, SLPX332M050A3P3, and B41231A6338M000 are confirmed RoHS3 compliant. The MAL225621332E3 RoHS status is not specified in the provided data.

Q: What is the maximum operating temperature for each part?

A: The 338LBA050M2BD, 380LX332M050H022, SLPX332M050A3P3, and B41231A6338M000 operate to 85°C maximum. The MAL225621332E3 extends to 105°C maximum, providing enhanced thermal margin for high-temperature applications.

Q: Do all substitute parts have the same ripple current ratings?

A: Ripple current ratings vary across the substitute parts. The 338LBA050M2BD specifies 2.4 A @ 120 Hz and 3 A @ 10 kHz. The 380LX332M050H022 provides 2.7 A @ 120 Hz and 3.1 A @ 20 kHz. The SLPX332M050A3P3 provides 2.41 A @ 120 Hz and 3.01 A @ 20 kHz. The B41231A6338M000 provides 2.97 A @ 120 Hz. Application-specific ripple current requirements should be verified against the selected substitute part.
