Parameter Comparison

Engineering Selection Recommendations

Both the LLG2E102MELB35 and B43630F2108M000 are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements, as both meet identical electrical and mechanical specifications for 1000 µF, 250 V aluminum electrolytic capacitor applications. The B43630F2108M000 provides documented ESR specification of 90 mOhm at 100 Hz, which may be relevant for applications requiring low impedance characteristics. Both parts are suitable for general purpose applications with through-hole mounting on PCBs requiring snap-in can capacitor configurations.

Frequently Asked Questions (FAQ)

Q: Can the B43630F2108M000 be used as a direct replacement for the LLG2E102MELB35?

A: Yes. Both parts share identical capacitance (1000 µF), voltage rating (250 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), and physical dimensions. The snap-in radial can package and through-hole mounting configuration are identical, enabling direct PCB substitution.

Q: Are there any differences in ripple current ratings between these parts?

A: The LLG2E102MELB35 specifies 3.32 A at 120 Hz low frequency ripple current, while the B43630F2108M000 specifies 3.01 A at 100 Hz. Both values are within acceptable operating parameters for the 1000 µF, 250 V rating class. Application-specific ripple current requirements should be evaluated against the actual operating frequency.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LLG2E102MELB35 and B43630F2108M000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: What is the significance of the ESR specification provided for the B43630F2108M000?

A: The ESR (Equivalent Series Resistance) of 90 mOhm at 100 Hz indicates the internal resistance of the capacitor. This specification is useful for applications where impedance characteristics affect circuit performance. The LLG2E102MELB35 does not provide this specification in the available data.

Q: Are the physical dimensions identical for both parts?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00mm), diameter (1.181" / 30.00mm), and maximum seated height (1.457" / 37.00mm), ensuring mechanical compatibility in snap-in mounting applications.
