Parameter Comparison

Engineering Selection Recommendations

Both the LKX2W151MESA25 and LGL2W151MELA25 are active production parts from Nichicon with identical electrical and mechanical specifications. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on availability and supply chain considerations, as they are functionally equivalent for through-hole PCB applications requiring 150 µF, 450 V aluminum electrolytic capacitors with snap-in mounting.

Frequently Asked Questions (FAQ)

Q: Can the LGL2W151MELA25 be used as a direct replacement for the LKX2W151MESA25?

A: Yes. Both parts share identical capacitance (150 µF), voltage rating (450 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-25°C ~ 105°C), lead spacing (10.00mm), physical dimensions (0.984" Dia × 1.063" Height), and snap-in radial can package. They are mechanically and electrically interchangeable.

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

A: The LGL2W151MELA25 specifies ripple current ratings of 740 mA @ 120 Hz and 1.0582 A @ 50 kHz. The LKX2W151MESA25 does not provide ripple current specifications in the available data. Both parts are suitable for their respective application categories (audio and general purpose).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LKX2W151MESA25 and LGL2W151MELA25 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.22.0040.

Q: What is the difference between the LKX and LGL series designations?

A: The series designation indicates the product line within Nichicon's aluminum electrolytic capacitor portfolio. Both series meet the specified electrical and mechanical requirements for this 150 µF, 450 V application.

Q: Are these parts suitable for PCB soldering or snap-in mounting only?

A: These parts are designed for through-hole snap-in mounting on PCBs. The radial leads and snap-in can design are intended for mechanical insertion into snap-in sockets or through-hole PCB pads.
