Substitute Part Grouping Explanation

Substitute parts for the EKMG160ELL331MHB5D are classified into three categories based on electrical and mechanical compatibility:

Direct Equivalents (Same Voltage Rating - 16V): Parts with identical 330 µF capacitance and 16 V voltage rating maintain full electrical compatibility. These include ECA-1CHG331 (Panasonic), UPS1C331MPD (Nichicon), UKA1C331MPD (Nichicon), EEU-FC1C331 (Panasonic), ELXY160ELL331MH15D (Chemi-Con), and ELXZ160ELL331MH12D (Chemi-Con).

Engineering Selection Recommendations

For Direct Replacement (16V Rating):

ECA-1CHG331 (Panasonic NHG-A series) is the primary direct equivalent. It maintains identical electrical specifications (330 µF, 16 V, 1000 Hrs @ 105°C) with equivalent ripple current ratings. The part is active and ROHS3 compliant. Height is slightly reduced at 0.492" compared to 0.512" of the original, which may provide space advantages in compact layouts.

EEU-FC1C331 (Panasonic FC series) offers enhanced performance with 2000-hour lifetime and higher ripple current capacity (360.8 mA @ 120 Hz, 555 mA @ 100 kHz). This part carries AEC-Q200 automotive qualification and is active. The reduced height of 0.453" provides additional layout flexibility.

ELXY160ELL331MH15D and ELXZ160ELL331MH12D (Chemi-Con LXY and LXZ series) provide extended lifetime of 3000 hours at 105°C with AEC-Q200 automotive qualification. ELXZ160ELL331MH12D offers the most compact height at 0.531" while maintaining performance. Both are active products suitable for applications requiring extended operational life.

For Upgraded Voltage Rating (25V):

ECA-1EHG331 (Panasonic NHG-A series) is recommended for applications requiring higher voltage margin. It maintains the same physical footprint and lead spacing while providing 25 V rating. The part is active and widely available with 119,223 units in stock.

Parts Not Recommended for New Designs:

UPS1C331MPD, UKA1C331MPD, UKA1E331MPD, and UVY1E331MPD are marked as "Not For New Designs" and should be used only for legacy system maintenance or repair applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 25V-rated capacitor in place of the 16V EKMG160ELL331MHB5D?

A: Yes. A 25V-rated capacitor with identical 330 µF capacitance and ±20% tolerance is electrically compatible. The higher voltage rating provides additional safety margin and does not degrade performance in 16V circuits. Physical dimensions and lead spacing remain identical, ensuring mechanical compatibility.

Q: What is the difference between the Chemi-Con KMG, LXY, and LXZ series?

A: The KMG series provides 1000-hour lifetime at 105°C for general-purpose applications. The LXY and LXZ series extend lifetime to 3000 hours at 105°C and include AEC-Q200 automotive qualification. LXZ offers a more compact height (0.531") compared to LXY (0.650"), while maintaining equivalent electrical performance.

Q: Are there height restrictions I should consider when selecting a substitute?

A: Yes. The original EKMG160ELL331MHB5D has a maximum seated height of 0.512" (13.00mm). Substitute parts vary in height: ECA-1CHG331 is 0.492", EEU-FC1C331 is 0.453", ELXZ160ELL331MH12D is 0.531", and ELXY160ELL331MH15D is 0.650". Verify that the selected substitute fits within your PCB layout constraints.

Q: What does "Not For New Designs" mean?

A: Parts marked "Not For New Designs" are legacy components that remain available for existing product support and repairs but are not recommended for new circuit designs. For new applications, select parts with "Active" product status such as ECA-1CHG331, EEU-FC1C331, or ELXY160ELL331MH15D.

Q: How do ripple current ratings affect component selection?

A: Ripple current capacity determines the maximum AC current the capacitor can handle without exceeding temperature limits. The original EKMG160ELL331MHB5D handles 260 mA @ 120 Hz and 390 mA @ 100 kHz. Substitutes with higher ripple current ratings (such as EEU-FC1C331 at 360.8 mA @ 120 Hz) provide additional margin for high-frequency switching applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance status of the original EKMG160ELL331MHB5D.

Q: Which substitute offers the best performance upgrade?

A: EEU-FC1C331 combines active product status, extended 2000-hour lifetime, higher ripple current capacity, AEC-Q200 automotive qualification, and reduced height in a single package. ELXY160ELL331MH15D and ELXZ160ELL331MH12D offer the longest lifetime (3000 hours) with automotive qualification for applications requiring maximum reliability.
