Substitute Part Grouping Explanation

Substitution of the LXY16VB331M8X15LL is determined by the following criteria:

Direct Electrical Equivalence: Capacitance (330 µF), voltage rating (16 V), and tolerance (±20%) must match exactly.

Mechanical Compatibility: Lead spacing (0.138" / 3.50 mm), case diameter (0.315" / 8.00 mm), and through-hole mounting type must be identical to ensure PCB compatibility without layout modification.

Thermal Performance: Lifetime rating of 3000 hours at 105°C and operating temperature range of -55°C to 105°C must be maintained.

Polarization: Polar configuration is required for all substitutes.

Upgrade Substitutes: Parts with higher voltage ratings (25 V) maintain all mechanical and thermal specifications while providing enhanced voltage margin. These are suitable for direct replacement in applications where the higher voltage rating does not create design conflicts.

Similar Substitutes: Parts with identical electrical and mechanical specifications but different product status or compliance certifications.

Direct Substitutes: Parts from alternative manufacturers meeting all electrical and mechanical parameters.

Engineering Selection Recommendations

For Direct Replacement (16 V Rating Required):

ELXY160ELL331MH15D is the primary recommendation. This Chemi-Con part maintains identical electrical specifications (330 µF, 16 V, ±20%, 3000 Hrs @ 105°C) and mechanical compatibility. The part is active and ROHS3 compliant. Height difference of 0.059" (1.50 mm) requires PCB layout verification but does not affect electrical function.

337KXM016M from Cornell Dubilier / Illinois Capacitor provides an alternative from a different manufacturer. All electrical and mechanical parameters are compatible. The reduced height (0.512" vs. 0.591") may provide layout advantages. Product status is active and ROHS3 compliant.

UPW1C331MPD from Nichicon is electrically and mechanically compatible but carries a "Not For New Designs" status. This part should be used only for legacy system maintenance where design changes are not feasible.

For Voltage Margin Enhancement (25 V Rating):

ELXZ250ELL331MH15D is recommended for applications where higher voltage margin is beneficial. This Chemi-Con upgrade maintains identical mechanical dimensions and thermal performance while providing 56% higher voltage rating. The part is active, ROHS3 compliant, and carries AEC-Q200 automotive qualification.

UPW1E331MPD6 from Nichicon provides equivalent 25 V performance with superior impedance characteristics (85 mOhms vs. 90 mOhms). This part is active and ROHS3 compliant. Higher ripple current capability (474.5 mA @ 120 Hz) supports demanding applications.

Compliance Considerations:

All recommended active substitutes are ROHS3 compliant, addressing environmental and regulatory requirements. The original LXY16VB331M8X15LL is RoHS non-compliant; transition to compliant alternatives is recommended for new production.

Frequently Asked Questions (FAQ)

Q: Can ELXY160ELL331MH15D directly replace LXY16VB331M8X15LL without PCB modification?

A: Yes, electrical and mechanical parameters are identical. The height difference of 0.059" (1.50 mm) requires verification that PCB clearance and component placement do not create conflicts. Lead spacing and case diameter are identical, ensuring footprint compatibility.

Q: What is the advantage of using a 25 V rated capacitor (ELXZ250ELL331MH15D or UPW1E331MPD6) instead of a 16 V part?

A: The 25 V rating provides additional voltage margin, reducing stress on the capacitor in applications subject to voltage transients or supply variations. Impedance is also lower in 25 V versions, improving ripple current performance. These upgrades are suitable when circuit design permits higher voltage ratings.

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

A: This designation indicates the manufacturer is phasing out this part number. While electrically and mechanically compatible, it should be used only for maintenance of existing systems. New designs should specify ELXY160ELL331MH15D, 337KXM016M, or 25 V upgrade options.

Q: Are there differences in ripple current handling between substitute options?

A: Yes. UPW1E331MPD6 (25 V) provides the highest ripple current at 474.5 mA @ 120 Hz. ELXZ250ELL331MH15D (25 V) provides 365 mA @ 120 Hz. The original and ELXY160ELL331MH15D (16 V) provide 277.5 mA @ 120 Hz. Selection depends on application ripple current requirements.

Q: What is the significance of impedance differences among substitutes?

A: Lower impedance improves capacitor performance under high-frequency ripple conditions and reduces voltage drop across the capacitor. UPW1E331MPD6 (85 mOhms) and ELXZ250ELL331MH15D (90 mOhms) offer superior high-frequency performance compared to the original (130 mOhms) and 337KXM016M (220 mOhms).

Q: Is AEC-Q200 certification required for this application?

A: AEC-Q200 certification is not required for general-purpose applications. ELXZ250ELL331MH15D carries this automotive qualification, making it suitable for automotive or mission-critical environments where enhanced reliability screening is specified.

Q: Can height differences affect circuit performance?

A: Height differences do not affect electrical performance. Verification is required only to confirm PCB layout clearance, component stacking, and mechanical assembly compatibility. All substitute options maintain identical lead spacing and case diameter.
