Substitute Part Grouping Explanation

Substitution eligibility for the 339LBA016M2ED is determined by strict equivalence across critical electrical and mechanical parameters. All substitute candidates must meet the following requirements:

Mandatory Matching Parameters:

• Capacitance: 33000 µF
• Voltage Rating: 16 V
• Tolerance: ±20%
• Case Diameter: 1.378" (35.00 mm)
• Height: 1.260" (32.00 mm)
• Lead Spacing: 0.394" (10.00 mm)
• Package Type: Radial, Can - Snap-In
• Mounting: Through Hole
• Operating Temperature: -40°C to 85°C
• Polarization: Polar

Acceptable Parameter Variations:

• ESR: May vary within performance envelope (25-25.12 mOhm range)
• Lifetime: Minimum 2000 hours at 85°C; higher ratings are acceptable
• Ripple Current: Minimum equivalence to original specification; higher ratings are acceptable

All substitute parts listed maintain compliance with RoHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

339LBA016M2ED (Original): Select this part when original design specification and component continuity are required. The part maintains active production status with established supply availability.

380LX333M016A022 (Direct Equivalent): This Cornell Dubilier Electronics offering provides direct functional equivalence with identical electrical specifications and mechanical dimensions. The part features improved lifetime performance at 3000 hours versus 2000 hours at 85°C, with comparable ESR characteristics. RoHS3 compliance and active status support direct substitution.

LLS1C333MELC (Upgrade): The Nichicon LLS series capacitor provides equivalent electrical and mechanical specifications with extended 3000-hour lifetime at 85°C. Higher ripple current capabilities at 50 kHz (6.279 A) and 120 Hz (5.46 A) support demanding applications. RoHS3 compliance and active production status support substitution.

B41231B4339M000 (Parametric Equivalent): The EPCOS - TDK Electronics B41231 series matches all critical electrical and mechanical parameters with 2000-hour lifetime at 85°C equivalent to the original. Higher ripple current performance at 120 Hz (6.41 A) provides operational margin. RoHS3 compliance permits substitution in compliant designs.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably in the same PCB assembly? A: All substitute parts listed maintain identical lead spacing (0.394"/10.00 mm), case diameter (1.378"/35.00 mm), and height (1.260"/32.00 mm) specifications. Through-hole snap-in mounting compatibility is preserved across all alternatives, permitting direct board-level substitution without assembly modifications.

Q: What is the impact of different ESR values on circuit performance? A: ESR differences within the specified range (25-25.12 mOhm) have minimal impact on general purpose applications. The 380LX333M016A022 (25 mOhm) and original 339LBA016M2ED (25.12 mOhm) remain functionally equivalent. Parts with unspecified ESR values (LLS1C333MELC and B41231B4339M000) are suitable for applications not requiring precise ESR control.

Q: Are the extended lifetime ratings (3000 hours) beneficial for my application? A: Parts with 3000-hour lifetime specifications (380LX333M016A022 and LLS1C333MELC) provide extended operational endurance compared to the 2000-hour original specification. This represents an improvement factor that may extend service life in temperature-sensitive applications, though both ratings remain suitable for general purpose use.

Q: Does ripple current rating variation affect component selection? A: All substitute parts meet or exceed the original ripple current specifications at 120 Hz (minimum 5.15 A). The 380LX333M016A022 (6.8 A) and B41231B4339M000 (6.41 A) provide additional margin for high-ripple applications. Selection based on application ripple current requirements ensures stable operation across all alternatives.

Q: Are all substitute parts RoHS3 and REACH compliant? A: All parts listed in this comparison maintain RoHS3 compliance and REACH unaffected status, supporting use in regulated environments and designs requiring environmental compliance certification.
