Engineering Selection Recommendations

ELXZ160ELL331MH12D (Chemi-Con LXZ Series)

This is the primary direct substitute for the LXZ16VB331M8X12LL. It maintains identical electrical specifications and mechanical footprint compatibility. The part is in active production status with AEC-Q200 automotive qualification. ROHS3 compliance provides regulatory advantage over the obsolete original part. Height difference of 0.059" (1.50 mm) is within standard PCB assembly tolerances. This substitute is recommended for direct replacement in existing designs.

ELXY160ELL331MH15D (Chemi-Con LXY Series)

This substitute maintains all required electrical parameters and mechanical compatibility. It is in active production with AEC-Q200 automotive qualification and ROHS3 compliance. The impedance is 130 mOhms compared to 120 mOhms in the original part. Height is 0.650" (16.50 mm), representing a 0.178" (4.50 mm) increase. This substitute is suitable for applications where increased height clearance is available on the PCB.

UPW1C331MPD (Nichicon UPW Series)

This substitute from an alternative manufacturer maintains all required electrical specifications and mechanical compatibility. The part is designated as "Not For New Designs," indicating it is in mature production phase. ROHS3 compliance is confirmed. Impedance is 117 mOhms and ripple current at 120 Hz is 360.75 mA, both within acceptable operating parameters. Height is 0.453" (11.50 mm), providing the most compact profile among available substitutes. This option is suitable for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the ELXZ160ELL331MH12D be used as a direct replacement for the LXZ16VB331M8X12LL?

A: Yes. The ELXZ160ELL331MH12D is electrically and mechanically equivalent to the LXZ16VB331M8X12LL. Both parts share identical capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, and physical footprint. The height difference of 0.059" (1.50 mm) is within standard PCB assembly tolerances and does not affect compatibility.

Q: What is the difference between the ELXY160ELL331MH15D and ELXZ160ELL331MH12D?

A: Both parts are manufactured by Chemi-Con and maintain identical electrical specifications. The primary differences are series designation (LXY versus LXZ) and physical height. The ELXY160ELL331MH15D is 0.650" (16.50 mm) tall compared to 0.531" (13.50 mm) for the ELXZ160ELL331MH12D. The ELXY series also has slightly higher impedance at 130 mOhms versus 120 mOhms. Selection between these parts depends on available PCB height clearance.

Q: Why is the UPW1C331MPD marked as "Not For New Designs"?

A: The "Not For New Designs" designation indicates the part is in mature production phase and may be subject to discontinuation. While the part remains electrically and mechanically compatible with the original LXZ16VB331M8X12LL, it is suitable for replacement in existing designs but not recommended for new product development. The ELXZ160ELL331MH12D is the preferred choice for new designs due to its active production status.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (ELXZ160ELL331MH12D, ELXY160ELL331MH15D, and UPW1C331MPD) are ROHS3 compliant. The original LXZ16VB331M8X12LL is RoHS non-compliant. Substitution provides regulatory compliance improvement for existing designs undergoing component refresh.

Q: What is the significance of AEC-Q200 qualification on the Chemi-Con substitutes?

A: AEC-Q200 is an automotive industry qualification standard for passive components. Both Chemi-Con substitutes (ELXZ160ELL331MH12D and ELXY160ELL331MH15D) carry this qualification, indicating they meet automotive-grade reliability and performance requirements. This qualification is not present on the original LXZ16VB331M8X12LL or the Nichicon UPW1C331MPD.

Q: Can I use the UPW1C331MPD in applications requiring automotive qualification?

A: The UPW1C331MPD does not carry AEC-Q200 qualification. If your application requires automotive-grade components, the ELXZ160ELL331MH12D or ELXY160ELL331MH15D are the appropriate choices.

Q: What is the impact of impedance differences among the substitute parts?

A: The original LXZ16VB331M8X12LL has 120 mOhms impedance. The ELXZ160ELL331MH12D matches this exactly at 120 mOhms. The ELXY160ELL331MH15D has 130 mOhms, and the UPW1C331MPD has 117 mOhms. These variations are within acceptable operating parameters for general-purpose and automotive applications. Impedance differences may affect ripple current performance in high-frequency switching applications, but all parts maintain the specified ripple current ratings at their respective impedance levels.

Q: Is height the only mechanical difference among the substitutes?

A: Yes. All substitute parts maintain identical lead spacing (0.138" / 3.50 mm) and diameter (0.315" / 8.00 mm). Height is the only mechanical dimension that varies. The UPW1C331MPD is the most compact at 0.453" (11.50 mm), followed by the original at 0.472" (12.00 mm), the ELXZ160ELL331MH12D at 0.531" (13.50 mm), and the ELXY160ELL331MH15D at 0.650" (16.50 mm).
