Engineering Selection Recommendations

For Direct Replacement (Same Voltage Rating - 35 V):

ELXY350ELL331MJ20S (Chemi-Con, Active Status) is the primary direct equivalent. This part maintains identical capacitance, voltage rating, tolerance, and electrical performance specifications. The height difference of 0.059" (1.50 mm) is within typical PCB layout tolerances for radial capacitors. This part is currently in active production status and is ROHS3 compliant, making it suitable for new designs and ongoing support applications.

UPW1V331MPD (Nichicon, Not For New Designs) provides electrical equivalence at the 35 V rating with comparable ripple current performance. However, its product status designation restricts use to legacy system support only. The reduced height of 0.630" (16.00 mm) may require PCB layout verification for clearance compatibility.

For Voltage Upgrade (50 V Rating):

UPW1H331MPD (Nichicon, Not For New Designs) offers a 50 V voltage rating while maintaining the same 330 µF capacitance and identical physical height of 0.787" (20.00 mm) as the original part. The higher impedance of 90 mOhms reflects the increased voltage rating. This upgrade substitute is suitable for applications requiring enhanced voltage margin, though its product status restricts use to legacy system support.

Compliance Considerations:

The original LXY35VB331M10X20LL is RoHS non-compliant. All identified substitutes (ELXY350ELL331MJ20S, UPW1V331MPD, UPW1H331MPD) are ROHS3 compliant, meeting current environmental and regulatory requirements for component procurement.

Frequently Asked Questions (FAQ)

Q: Can ELXY350ELL331MJ20S be used as a direct replacement for LXY35VB331M10X20LL?

A: Yes. ELXY350ELL331MJ20S is a direct equivalent with identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (10.00 mm), and electrical performance. The height difference of 1.50 mm is within standard PCB layout tolerances for radial capacitors. This part is in active production status and ROHS3 compliant.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents (ELXY350ELL331MJ20S, UPW1V331MPD) maintain the 35 V voltage rating of the original part. The upgrade substitute (UPW1H331MPD) provides a 50 V voltage rating for the same 330 µF capacitance, offering increased voltage margin. All three maintain identical lead spacing, case diameter, and mounting type.

Q: Does the height difference between substitutes affect PCB compatibility?

A: Height variations exist among substitutes: ELXY350ELL331MJ20S (21.50 mm), UPW1V331MPD (16.00 mm), and UPW1H331MPD (20.00 mm). The original part height is 20.00 mm. PCB layout clearance must be verified for components with different heights, particularly UPW1V331MPD at 16.00 mm and ELXY350ELL331MJ20S at 21.50 mm.

Q: Are there differences in ripple current ratings among substitutes?

A: Yes. At 120 Hz, ELXY350ELL331MJ20S and the original part both specify 520 mA, while UPW1V331MPD and UPW1H331MPD specify 682.5 mA and 669.5 mA respectively. At 100 kHz, all parts specify approximately 1.03–1.05 A. These differences reflect design variations between manufacturers but do not affect functional equivalence for the specified 330 µF, 35 V application.

Q: Why is UPW1V331MPD marked "Not For New Designs"?

A: This product status designation indicates the part is in legacy support phase. It remains available for existing system maintenance and repair but should not be selected for new product designs. For new designs, ELXY350ELL331MJ20S (Active Status) is the recommended choice.

Q: Can UPW1H331MPD (50 V) be used in a circuit designed for 35 V?

A: Yes. A 50 V rated capacitor is electrically compatible with a 35 V circuit. The higher voltage rating provides additional safety margin and does not degrade performance. The same 330 µF capacitance and physical form factor ensure mechanical and electrical compatibility.

Q: What is the significance of RoHS compliance for these substitutes?

A: All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for component procurement and assembly. The original LXY35VB331M10X20LL is RoHS non-compliant. Substitution with ROHS3-compliant parts ensures compliance with modern manufacturing and environmental standards.

Q: How do impedance differences affect circuit performance?

A: Impedance values (62 mOhms for ELXY350ELL331MJ20S, 68 mOhms for UPW1V331MPD, 90 mOhms for UPW1H331MPD) reflect internal resistance characteristics. For general-purpose applications, these variations are within acceptable tolerances. Applications with strict impedance requirements should verify performance through circuit simulation or testing.
