Engineering Selection Recommendations

ELXY350ELL221MJ16S (Chemi-Con LXY Series)

This part is the direct equivalent within the Chemi-Con LXY series. It maintains identical electrical specifications and mechanical dimensions as the main part. The ELXY350ELL221MJ16S is currently in active production status and is ROHS3 compliant. The primary mechanical difference is a maximum height of 0.689" (17.50 mm) versus 0.630" (16.00 mm) on the original part. This part carries AEC-Q200 automotive qualification. Selection of this part is appropriate for applications requiring continued use of Chemi-Con components with modern compliance certifications.

UPM1V221MPD6AA (Nichicon UPM Series)

This Nichicon part provides electrical equivalence with identical capacitance, voltage rating, and tolerance. It is rated for AEC-Q200 automotive applications and maintains the same maximum height of 0.630" (16.00 mm) as the original part. The impedance is slightly higher at 90 mOhms compared to 84 mOhms. This part is currently in active production. Selection is appropriate for applications requiring automotive-grade components with modern compliance.

UPW1H221MPD (Nichicon UPW Series)

This part provides a voltage upgrade to 50 V while maintaining 220 µF capacitance and ±20% tolerance. It is suitable for applications where higher voltage margin is beneficial. The part is classified as "Not For New Designs" and carries ROHS3 compliance. The impedance is higher at 119 mOhms. This part should be considered only for legacy system support where voltage derating is not a constraint.

UPW1V221MPD (Nichicon UPW Series)

This part provides electrical equivalence at 35 V with identical capacitance and tolerance. It is currently in active inventory with 19,971 pieces available. The maximum height is 0.492" (12.50 mm), which is significantly shorter than the original part. This part is classified as "Not For New Designs" but offers the largest available inventory. Selection is appropriate only for applications where the reduced height does not create mechanical conflicts and where legacy component support is required.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor (UPW1H221MPD) in place of the 35 V original part?

A: Yes. A higher voltage rating is electrically compatible with circuits designed for 35 V operation. The 50 V part will function correctly in the 35 V application. However, the impedance increases to 119 mOhms, which may affect ripple current performance in high-frequency applications.

Q: What is the significance of the height differences between substitute parts?

A: The original LXY35VB221M10X16LL has a maximum height of 0.630" (16.00 mm). The ELXY350ELL221MJ16S is 0.689" (17.50 mm) tall, and the UPW1V221MPD is 0.492" (12.50 mm) tall. Height differences affect PCB layout clearance and mechanical fit. Verify that the substitute part height does not interfere with adjacent components or enclosure constraints before selection.

Q: Are all substitute parts RoHS compliant?

A: The original LXY35VB221M10X16LL is RoHS non-compliant. The ELXY350ELL221MJ16S, UPW1H221MPD, and UPW1V221MPD are all ROHS3 compliant. The RoHS status of UPM1V221MPD6AA is not specified in the provided data. Verify RoHS compliance requirements for your application before final selection.

Q: What does "Not For New Designs" mean for UPW1H221MPD and UPW1V221MPD?

A: This designation indicates that the manufacturer is not recommending these parts for new product development. These parts may have limited future availability or ongoing support. They are suitable for legacy system maintenance and repair but should not be selected for new designs where alternatives are available.

Q: Which substitute part has the best inventory availability?

A: UPW1V221MPD has the largest inventory with 19,971 pieces in stock. ELXY350ELL221MJ16S has 5,591 pieces, UPW1H221MPD has 3,500 pieces, and UPM1V221MPD6AA has 996 pieces available.

Q: What is the difference between "Similar" and "Upgrade" substitute parts?

A: Similar parts maintain equivalent electrical and mechanical specifications to the original component. Upgrade parts offer enhanced specifications, such as higher voltage ratings, automotive certifications (AEC-Q200), or improved compliance status (ROHS3). Selection depends on application requirements and compliance mandates.

Q: Can I interchange these parts without PCB modification?

A: Mechanical compatibility requires verification of height clearance. The ELXY350ELL221MJ16S is taller than the original part and may require clearance verification. The UPW1V221MPD is shorter and will fit in the same footprint. All parts share identical lead spacing (0.197" / 5.00 mm) and case diameter (0.394" / 10.00 mm), so PCB pad layout remains unchanged.
