Engineering Selection Recommendations

ELXY500ELL331MJ30S (Chemi-Con, Active Status)

This part is the primary substitute for the LXY50VB331M10X30LL. It maintains identical electrical specifications (330 µF, 50 V, ±20%, 5000 Hrs @ 105°C) and mechanical compatibility (lead spacing, diameter, radial configuration). The ELXY500ELL331MJ30S is currently in active production status, ensuring long-term availability. It carries AEC-Q200 automotive qualification and ROHS3 compliance, representing a compliance upgrade from the original obsolete part. Physical height increases from 30.00mm to 31.50mm, which requires verification against PCB layout constraints. This part is recommended for new designs and ongoing production support.

UPW1H331MPD (Nichicon, Not For New Designs)

This Nichicon part provides electrical equivalence with identical capacitance, voltage, tolerance, and thermal specifications. It meets the 5000-hour lifetime requirement at 105°C and maintains the same operating temperature range. Lead spacing and diameter are identical. The UPW1H331MPD carries ROHS3 compliance. However, this part is classified as "Not For New Designs," indicating limited future availability. The height is significantly shorter at 20.00mm compared to the original 30.00mm, providing a potential advantage for space-constrained applications. Impedance is higher at 90 mOhms versus 54 mOhms. This part is suitable for legacy system maintenance and repair where inventory exists, but ELXY500ELL331MJ30S is preferred for new applications.

Frequently Asked Questions (FAQ)

Q: Can the ELXY500ELL331MJ30S be used as a direct replacement for the LXY50VB331M10X30LL?

A: Yes. Both parts share identical electrical specifications (330 µF, 50 V, ±20% tolerance, 5000 Hrs @ 105°C) and mechanical compatibility (lead spacing 5.00mm, diameter 10.00mm, radial through-hole configuration). The height difference of 1.50mm (31.50mm vs. 30.00mm) must be verified against PCB layout to ensure clearance.

Q: What is the significance of the AEC-Q200 rating on the ELXY500ELL331MJ30S?

A: AEC-Q200 is an automotive qualification standard. This certification indicates the part meets automotive reliability and quality requirements. It does not affect electrical compatibility but indicates enhanced quality assurance and testing protocols.

Q: Why is the UPW1H331MPD marked "Not For New Designs"?

A: This designation indicates the manufacturer is phasing out the part. While it remains electrically and mechanically compatible, it is not recommended for new product designs due to uncertain long-term availability. It is suitable for maintenance and repair of existing systems.

Q: Does the impedance difference between UPW1H331MPD (90 mOhms) and the original part (54 mOhms) affect compatibility?

A: Higher impedance may affect high-frequency ripple current performance. The UPW1H331MPD delivers 1.03 A @ 100 kHz versus 1.26 A for the original part. Applications requiring maximum ripple current handling should use ELXY500ELL331MJ30S to maintain original specifications.

Q: Are there height constraints when using ELXY500ELL331MJ30S?

A: Yes. The ELXY500ELL331MJ30S is 31.50mm tall versus 30.00mm for the original LXY50VB331M10X30LL. PCB layout must accommodate this 1.50mm increase. The UPW1H331MPD is shorter at 20.00mm, providing additional clearance if space is limited.

Q: What is the difference between RoHS non-compliant and ROHS3 compliant?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive, restricting lead, cadmium, mercury, and other hazardous materials. The original LXY50VB331M10X30LL does not meet this standard. Both substitute parts are ROHS3 compliant, representing an environmental and regulatory upgrade.

Q: Can I use either substitute part interchangeably?

A: Both parts are electrically and mechanically compatible, but selection depends on application requirements. ELXY500ELL331MJ30S is recommended for new designs due to active production status and automotive qualification. UPW1H331MPD is suitable for legacy system maintenance where inventory exists, provided height and impedance specifications are acceptable.
