338LBB063M2CD Equivalent & Substitute Parts

Part Overview

The 338LBB063M2CD is a 3300 µF, 63 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the LBB 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 in product status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, manufacturing discontinuation, or application-specific performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 338LBB063M2CD is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance: 3300 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Package / Case: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Size / Dimension: 0.984" Dia (25.00mm) (exact match required)
• Height - Seated (Max): 1.260" (32.00mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All identified substitute parts meet these criteria. Variations in operating temperature range, lifetime ratings at elevated temperatures, and ripple current specifications do not preclude substitution when the above parameters are equivalent.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active in product status and fully compliant with ROHS3 and REACH requirements, matching the regulatory profile of the 338LBB063M2CD.

381LX332M063J022 (Cornell Dubilier Electronics): This part offers an extended operating temperature range of -40°C to 105°C and a lifetime rating of 3000 Hrs @ 105°C, compared to the main part's 3000 Hrs @ 85°C. This represents an upgrade in thermal performance while maintaining all other electrical and mechanical equivalence.

861220784007 (Würth Elektronik): This part maintains identical electrical and mechanical specifications to the main part, with operating temperature range of -40°C to 85°C and 3000 Hrs @ 85°C lifetime. Ripple current specifications at low and high frequencies are provided.

LLS1J332MELA (Nichicon): This part maintains identical electrical and mechanical specifications to the main part, with operating temperature range of -40°C to 85°C and 3000 Hrs @ 85°C lifetime. Ripple current specifications at low and high frequencies are provided.

Selection among these substitutes is based on availability, packaging requirements (Bulk or Tray), and thermal performance needs of the application.

Frequently Asked Questions (FAQ)

Q: Can 381LX332M063J022 be used as a direct replacement for 338LBB063M2CD?

A: Yes. The 381LX332M063J022 meets all critical electrical and mechanical parameters: 3300 µF capacitance, 63 V voltage rating, ±20% tolerance, identical physical dimensions, lead spacing, and through-hole snap-in package. Both are ROHS3 compliant and REACH unaffected. The 381LX332M063J022 provides extended temperature operation to 105°C.

Q: What is the difference between the main part and the Würth Elektronik substitute 861220784007?

A: The 861220784007 is electrically and mechanically equivalent to the 338LBB063M2CD. Both share identical capacitance (3300 µF), voltage rating (63 V), tolerance (±20%), operating temperature range (-40°C to 85°C), and physical dimensions. The primary difference is manufacturer and packaging format (Tray versus original packaging).

Q: Are all substitute parts available in the same packaging?

A: No. The 338LBB063M2CD is supplied in standard packaging. The 381LX332M063J022 is supplied in Bulk packaging. The 861220784007 is supplied in Tray packaging. The LLS1J332MELA is supplied in Bulk packaging. Packaging format should be verified against procurement requirements.

Q: Do the substitute parts have the same ESR (Equivalent Series Resistance) specifications?

A: The main part 338LBB063M2CD specifies ESR of 75.36 mOhm @ 120 Hz. ESR values are not provided for the substitute parts in the available data. Ripple current specifications are provided for 861220784007 and LLS1J332MELA, which serve as performance indicators for high-frequency applications.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, for through-hole applications. All parts share identical lead spacing (0.394" / 10.00mm), diameter (0.984" / 25.00mm), and height (1.260" / 32.00mm). PCB footprints designed for the 338LBB063M2CD accommodate all listed substitutes without modification.

Q: What is the moisture sensitivity level for these capacitors?

A: The 338LBB063M2CD has MSL 1 (Unlimited). The 381LX332M063J022 also has MSL 1 (Unlimited). The 861220784007 and LLS1J332MELA list MSL as Not Applicable, indicating no moisture sensitivity restrictions for these products.

Q: Are all parts compliant with current environmental regulations?

A: Yes. All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
