Engineering Selection Recommendations

ELZA160ELL332MK25S (Chemi-Con LZA Series)

This substitute provides a voltage upgrade from 10 V to 16 V while maintaining all other critical parameters. The 16 V rating provides additional voltage margin in applications where the circuit voltage may approach the 10 V limit. The ELZA160ELL332MK25S is AEC-Q200 rated, indicating automotive-grade qualification. Physical dimensions are compatible with the main part, with a maximum seated height of 1.043" (26.50mm) compared to 1.063" (27.00mm) for the 338KXM010M. Impedance is reduced to 22 mOhms, providing improved high-frequency performance. This part is ROHS3 compliant and REACH unaffected. Inventory availability is higher at 1850 units.

UPA1A332MHD (Nichicon UPA Series)

This substitute maintains the identical 10 V voltage rating as the main part, providing a direct parametric equivalent. The UPA1A332MHD is designed for general purpose applications and shares all critical electrical and mechanical specifications with the 338KXM010M. Physical dimensions and lead spacing are identical. Impedance is reduced to 22 mOhms. The part is ROHS3 compliant. REACH status is listed as affected, which requires verification of specific substance compliance in applications subject to REACH regulations. Inventory availability is 706 units.

Selection Basis:

• Both substitutes are active products with confirmed production status
• Both maintain the required 3300 µF capacitance and ±20% tolerance
• Both are through-hole, radial can packages with identical lead spacing
• Both support the full -55°C ~ 105°C operating temperature range
• Both provide 5000 hours lifetime at 105°C
• All three parts are ROHS3 compliant

The choice between substitutes depends on circuit voltage requirements and regulatory compliance needs. The ELZA160ELL332MK25S is suitable for applications requiring voltage margin or automotive qualification. The UPA1A332MHD is suitable for direct replacement in general purpose applications with identical voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can the ELZA160ELL332MK25S (16 V) be used in place of the 338KXM010M (10 V)?

A: Yes. The ELZA160ELL332MK25S is a valid substitute with a higher voltage rating. A capacitor with a higher voltage rating can be used in circuits designed for lower voltages. The 16 V rating provides additional voltage margin and does not affect circuit operation at 10 V or below.

Q: Can the UPA1A332MHD (10 V) be used in place of the 338KXM010M (10 V)?

A: Yes. The UPA1A332MHD is a parametric equivalent with identical voltage, capacitance, tolerance, and physical specifications. It is a direct replacement for general purpose applications.

Q: Are the physical dimensions compatible with the PCB layout?

A: All three parts share identical lead spacing of 0.197" (5.00mm) and diameter of 0.492" (12.50mm). The ELZA160ELL332MK25S has a maximum seated height of 1.043" (27.00mm), while both the 338KXM010M and UPA1A332MHD have 1.063" (27.00mm). All three parts are compatible with standard through-hole PCB layouts designed for radial aluminum electrolytic capacitors in this size class.

Q: What is the difference in ripple current handling?

A: The 338KXM010M specifies 2.078 A at 120 Hz and 2.77 A at 100 kHz. The ELZA160ELL332MK25S specifies 1.763 A at 120 Hz and 2.35 A at 100 kHz. The UPA1A332MHD specifies 1.938 A at 120 Hz and 2.28 A at 100 kHz. All three parts meet or exceed typical ripple current requirements for general purpose and automotive applications. Selection should be based on specific circuit ripple current specifications.

Q: What is the significance of the impedance values?

A: The 338KXM010M has an impedance of 45 mOhms, while both the ELZA160ELL332MK25S and UPA1A332MHD have 22 mOhms. Lower impedance indicates better high-frequency performance and reduced voltage ripple. Both substitutes provide improved impedance characteristics compared to the main part.
