Engineering Selection Recommendations

Direct Substitutes (Primary Selection Tier):

The following parts provide direct functional replacement with identical electrical ratings and superior performance characteristics:

158KBM050M (Cornell Dubilier / Illinois Capacitor): Active product status with doubled lifetime (10,000 Hrs @ 105°C). Slightly reduced height (1.496" vs 1.575") improves board space efficiency. Higher ripple current capability (1.89 A @ 120 Hz) provides thermal margin.
EKY-500ELL152MLP1S (Chemi-Con): Active product status with 10,000-hour lifetime. Compact height (1.457") reduces PCB footprint. Lower impedance (19 mOhm) enhances high-frequency ripple current performance.
EKYB500ELL152MLN3S (Chemi-Con): Active product status with 10,000-hour lifetime. Compact height (1.240") suitable for space-constrained layouts. Lowest profile option among direct substitutes.
EKZN500ELL152MLN3S (Chemi-Con): Active product status with 10,000-hour lifetime. Highest ripple current capability (2.418 A @ 120 Hz, 4.03 A @ 100 kHz) for demanding thermal applications.

Secondary Substitutes (Limited Application):

UHE1H152MHD (Nichicon): Meets electrical requirements with 10,000-hour lifetime. Product status "Not For New Designs" restricts use to legacy product support only.

Not Recommended for Direct Substitution:

UPW1J152MHD (Nichicon): Voltage rating of 63 V exceeds the 50 V requirement. Larger case diameter (0.709" vs 0.630") may cause physical interference. Product status "Not For New Designs" and reduced lifetime (8,000 Hrs) make this unsuitable except in specific voltage-upgrade scenarios.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SXR152M050ST with any part that has 1500 µF and 50 V rating?

A: No. Beyond capacitance and voltage, the case diameter (0.630"), lead spacing (0.295"), mounting type (through-hole radial), and package footprint must match the original design. Physical fit on the PCB is as critical as electrical specifications.

Q: What is the impact of different heights among substitute parts?

A: Height variations directly affect PCB layout compatibility. Shorter components (such as EKYB500ELL152MLN3S at 1.240") require verification that board clearances and mechanical constraints permit the change. Verify against design specifications before substitution.

Q: Is there a performance difference between the substitute parts?

A: Yes. The key performance differences are ripple current capacity and ESR. Higher ripple current ratings (such as EKZN500ELL152MLN3S at 2.418 A @ 120 Hz) indicate improved thermal performance under AC current conditions. Lower impedance values (19 mOhm) provide better high-frequency ripple filtering.

Q: Why is UPW1J152MHD listed as a similar part but not a direct substitute?

A: UPW1J152MHD has a 63 V voltage rating rather than 50 V, a larger case diameter (0.709" vs 0.630"), and a reduced lifetime (8,000 Hrs vs 10,000 Hrs). While the capacitance remains 1500 µF, the larger physical dimensions may cause PCB interference. Use this part only in applications where a higher voltage rating is required and physical space permits the larger case.

Q: Which substitute should I select for new designs?

A: Select from active-status parts: 158KBM050M, EKY-500ELL152MLP1S, EKYB500ELL152MLN3S, or EKZN500ELL152MLN3S. Avoid parts marked "Not For New Designs" (UHE1H152MHD and UPW1J152MHD) unless supporting legacy products.

Q: How do I verify compatibility with my specific application?

A: Cross-check capacitance, voltage rating, case diameter, height, lead spacing, ripple current requirements, and operating temperature range against your schematic and PCB layout. Request samples for thermal testing if ripple current conditions approach component ratings.
