108LMU200M2EE

Part Overview

The 108LMU200M2EE is a 1000 µF, 200 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor. This radial, can-style snap-in component is designed for general-purpose applications requiring polarized electrolytic energy storage at high voltage. The part is classified as obsolete; equivalent and substitute models from active manufacturers are available to ensure design continuity and procurement reliability.

Substitute Part Grouping Explanation

Substitution logic for 1000 µF, 200 V aluminum electrolytic capacitors with snap-in radial packages is determined by the following criteria:

Core electrical parameters (non-negotiable):

Capacitance: 1000 µF
Tolerance: ±20%
Voltage rating: 200 V (minimum)
Polarization: Polar
Package: Radial, Can - Snap-In

Mechanical parameters (must match for direct physical substitution):

Lead spacing: 0.394" (10.00 mm)
Case diameter: 1.378" (35.00 mm)
Mounting type: Through Hole

Performance parameters (variable based on application requirements):

Lifetime at 105°C: ranges from 2000 to 10000 hours
ESR (Equivalent Series Resistance): ranges from 149 mOhm to 249 mOhm
Ripple current capability: varies by frequency and design

Substitute parts are organized into three categories: direct equivalents (same 200 V rating with varying lifetime), and upgrade variants (higher voltage rating of 250 V or extended lifetime to 10000 hours).

Frequently Asked Questions (FAQ)

Q: Can I use the LGN2E102MELC35 (250 V) as a direct replacement for the 108LMU200M2EE (200 V)? A: Yes. The 250 V rating provides a higher safety margin while maintaining identical capacitance (1000 µF), tolerance (±20%), package dimensions, and lead spacing. The higher voltage rating does not degrade performance in 200 V applications.

Q: What is the difference between the compact (25 mm height) and standard (37 mm height) variants? A: The seated height is the primary physical difference. Compact variants (LAR2D102MELC25, LGN2D102MELC25, LGU2D102MELC) fit in space-constrained PCB layouts. Standard height parts (B43255A2108M, LGN2E102MELC35, LGR2D102MELC35) match the original 108LMU200M2EE form factor. Electrical performance and lead spacing remain identical.

Q: Does ESR (Equivalent Series Resistance) affect my design? A: ESR determines voltage drop and heat generation at ripple current frequencies. The 108LMU200M2EE specifies 165.8 mOhm @ 120 Hz. The 381LR102M200A022 offers lower ESR (149 mOhm), reducing heat dissipation in high-ripple applications. EKMH201VNN102MA35S has higher ESR (249 mOhm). Select based on ripple current specification in your circuit.

Q: Why should I choose a 3000-hour or 10,000-hour lifetime part instead of the original 2000-hour specification? A: Extended lifetime parts reduce failure risk in long-term operational environments. The 10,000-hour variant (LGR2D102MELC35) extends calendar life at rated temperature. Use for critical, long-deployment applications requiring maximum reliability.

Q: Are all substitute parts RoHS3 compliant? A: All listed substitute parts are RoHS3 compliant and REACH unaffected, ensuring compatibility with current environmental regulations and supply chain requirements.

Q: What if my PCB layout requires the exact original seated height of 1.457"? A: Use B43255A2108M, LGN2E102MELC35, LGR2D102MELC35, or LKX2E102MESC35, all of which match the 37.00 mm height specification.
