Engineering Selection Recommendations

ELXY500ELL820MH15D (Chemi-Con):

This substitute is the primary equivalent for the LXY50VB82RM8X15LL. It maintains identical electrical specifications and mechanical compatibility. The ELXY500ELL820MH15D is currently in active product status, ensuring long-term availability. It carries AEC-Q200 automotive qualification and ROHS3 compliance, making it suitable for both legacy system maintenance and new design applications. Height variation (16.50mm vs. 15.00mm) is within acceptable tolerance for standard through-hole PCB layouts. This part is the recommended choice for direct replacement.

UPW1H820MPD (Nichicon):

This substitute meets all critical electrical and mechanical parameters. The UPW1H820MPD is manufactured by Nichicon and carries ROHS3 compliance. Product status is listed as Not For New Designs, indicating this part is suitable for maintenance and repair of existing systems but not recommended for new design implementations. The significantly shorter height (11.50mm vs. 15.00mm) provides additional board clearance. Ripple current performance exceeds the original specification at both 120 Hz and 100 kHz. Impedance is slightly elevated (234 mOhms vs. 200 mOhms) but remains within acceptable operational parameters. This part is suitable for legacy system support where component availability is prioritized.

Selection Criteria:

For new designs or systems requiring extended product lifecycle support, select ELXY500ELL820MH15D. For maintenance and repair of existing systems where the original LXY50VB82RM8X15LL is no longer available, either substitute is acceptable based on inventory and delivery requirements.

Frequently Asked Questions (FAQ)

Q: Can ELXY500ELL820MH15D be used as a direct replacement for LXY50VB82RM8X15LL?

A: Yes. The ELXY500ELL820MH15D is electrically and mechanically compatible. All critical parameters match: 82 µF capacitance, 50 V rating, ±20% tolerance, 3000 Hrs @ 105°C lifetime, identical lead spacing (3.50mm), and radial through-hole package. Height difference (16.50mm vs. 15.00mm) is within standard PCB clearance tolerances.

Q: What is the difference between the two substitute parts?

A: Both substitutes meet electrical and mechanical requirements. ELXY500ELL820MH15D is manufactured by Chemi-Con (same as original), is in active product status, and carries AEC-Q200 automotive qualification. UPW1H820MPD is manufactured by Nichicon, is marked Not For New Designs, and has a shorter physical height (11.50mm). Both are ROHS3 compliant.

Q: Why is the LXY50VB82RM8X15LL obsolete?

A: The original part is listed as obsolete, meaning it is no longer manufactured or supported by Chemi-Con. Substitute parts ensure continued availability for system maintenance and repair.

Q: Does height variation affect PCB compatibility?

A: Height variation must be evaluated against specific PCB clearance requirements. ELXY500ELL820MH15D (16.50mm) is 1.50mm taller than the original. UPW1H820MPD (11.50mm) is 3.50mm shorter. Standard through-hole PCB designs typically accommodate these variations. Verify clearance in your specific application.

Q: Are both substitutes RoHS compliant?

A: Yes. Both ELXY500ELL820MH15D and UPW1H820MPD are ROHS3 compliant. The original LXY50VB82RM8X15LL is RoHS non-compliant, reflecting its obsolete status.

Q: Which substitute should I choose for a new design?

A: ELXY500ELL820MH15D is the recommended choice for new designs. It is in active product status, carries AEC-Q200 automotive qualification, and is manufactured by the same supplier as the original part.

Q: Can UPW1H820MPD be used in new designs?

A: UPW1H820MPD is marked Not For New Designs. It is suitable for maintenance and repair of existing systems but should not be selected for new design implementations.

Q: What parameters must match for substitution?

A: Critical parameters that must match are capacitance (82 µF), voltage rating (50 V), tolerance (±20%), lifetime (3000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), lead spacing (3.50mm), package type (radial can), and mounting type (through hole). Ripple current, impedance, and height may vary within acceptable operational limits.
