Engineering Selection Recommendations

All three parts—MAL215919829E3, B43644J6826M000, and LGX2H820MELZ35—maintain Active product status and are ROHS3 compliant with REACH unaffected designation. Selection between these parts is based on availability and application-specific performance requirements within the specified electrical and mechanical parameters.

The B43644J6826M000 (EPCOS - TDK Electronics) offers lower ESR at 960 mOhm compared to the MAL215919829E3 at 1.58 Ohm, which may provide performance advantages in applications sensitive to impedance characteristics. The LGX2H820MELZ35 (Nichicon) does not specify ESR but provides higher ripple current capability at high frequency (1.0296 A @ 50 kHz) compared to the MAL215919829E3 (966 mA @ 10 kHz).

All parts are suitable for general purpose applications and maintain identical voltage, capacitance, tolerance, lifetime, temperature range, and physical specifications.

Frequently Asked Questions (FAQ)

Q: Can B43644J6826M000 be used as a direct replacement for MAL215919829E3?

A: Yes. Both parts share identical capacitance (82 µF), voltage rating (500 V), tolerance (±20%), lifetime (5000 Hrs @ 105°C), operating temperature range (-25°C ~ 105°C), and physical dimensions (0.866" Dia, 1.457" height, 10.00mm lead spacing). The radial, can snap-in package and through-hole mounting are identical, ensuring mechanical and electrical interchangeability.

Q: What is the difference between the three substitute parts?

A: The primary differences are manufacturer origin and ESR characteristics. The MAL215919829E3 has ESR of 1.58 Ohm @ 100Hz. The B43644J6826M000 has lower ESR at 960 mOhm @ 100Hz. The LGX2H820MELZ35 does not specify ESR but offers higher ripple current at high frequency (1.0296 A @ 50 kHz). All other electrical and mechanical parameters are identical.

Q: Are all three parts ROHS3 compliant?

A: Yes. MAL215919829E3, B43644J6826M000, and LGX2H820MELZ35 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
