Substitute Part Grouping Explanation

Substitute parts for the 338LBA100M2EE are qualified based on matching the following critical electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Capacitance: 3300 µF (matching value)
• Voltage Rating: 100 V (matching or higher rated voltage)
• Tolerance: ±20% (matching tolerance classification)
• Polarization: Polar (matching polarity requirement)

Mechanical Equivalence Requirements:

• Package Type: Radial, Can - Snap-In (identical package configuration)
• Mounting Type: Through Hole (identical mounting method)
• Lead Spacing: 0.394" (10.00mm) (pin-to-pin distance)
• Physical Dimensions: 1.378" Dia × 1.457" Height max (same footprint and envelope)

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected
• Operating Temperature Range: -40°C ~ 85°C

The following parts meet all these requirements and are direct substitutes:

1. LLS2A332MELC (Nichicon) - Direct Manufacturer Equivalent
2. B41231C9338M000 (EPCOS - TDK Electronics) - Parametric Equivalent

Parameter Comparison

Engineering Selection Recommendations

All three parts (338LBA100M2EE, LLS2A332MELC, and B41231C9338M000) are suitable for direct substitution within applications designed for 3300 µF, 100 V aluminum electrolytic capacitors with snap-in mounting. Selection between these parts may be based on the following factors:

Product Availability: The Nichicon LLS2A332MELC offers an extended lifetime rating of 3000 hours at 85°C, compared to 2000 hours for both the original Cornell Dubilier part and the EPCOS alternative. This extended rating may provide additional operational margin in temperature-dependent applications.

Compliance Certification: All three parts maintain ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements for electronic component procurement.

Ripple Current Ratings: The Nichicon LLS2A332MELC specifies 4.07 A @ 120 Hz low-frequency ripple current capability, while the EPCOS B41231C9338M000 specifies 4.85 A @ 120 Hz, both exceeding the original 3.58 A specification.

Frequently Asked Questions (FAQ)

Q: Can the Nichicon LLS2A332MELC be used as a direct replacement for the Cornell Dubilier 338LBA100M2EE?

A: Yes. Both parts share identical electrical specifications (3300 µF, ±20% tolerance, 100 V rated), mechanical dimensions, lead spacing, and package configuration (radial, can snap-in through-hole). The Nichicon part provides extended lifetime (3000 hours vs. 2000 hours at 85°C) at the same operating temperature range.

Q: What does "snap-in" package configuration mean for mounting?

A: Snap-in refers to the mechanical connection method where the capacitor is inserted and retained through a spring-contact mechanism on a circuit board. All three substitute parts use identical snap-in mounting with 0.394" (10.00mm) lead spacing, ensuring mechanical interchangeability in existing board designs.

Q: Are there differences in ESR (Equivalent Series Resistance) between these parts?

A: The Cornell Dubilier 338LBA100M2EE specifies 100.48 mOhm @ 120 Hz. ESR specifications for the Nichicon and EPCOS parts were not provided in the technical data. Applications sensitive to ESR performance should confirm compatibility with detailed manufacturer datasheets.

Q: Do all three parts meet modern regulatory compliance?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, suitable for procurement in regulated markets requiring environmental compliance certification.

Q: What is the operating temperature range for all substitute parts?

A: All three parts operate within -40°C to 85°C. This matches the original specification and ensures compatibility in applications designed for this temperature envelope.
