Engineering Selection Recommendations

ELXY160ELL271MJC5S (Chemi-Con LXY Series Equivalent)

This substitute maintains identical electrical specifications and mechanical dimensions to the LXY16VB271M10X12LL. The ELXY160ELL271MJC5S is an active product with ROHS3 compliance and AEC-Q200 automotive qualification. The height difference of 0.059" (1.50 mm) requires verification of available PCB clearance. This component is the direct equivalent for applications requiring same-manufacturer continuity and is suitable for general-purpose and automotive applications.

UPM1C271MPD6CM (Nichicon UPM Series Upgrade)

This upgrade substitute is manufactured by Nichicon and meets all critical electrical and mechanical parameters. The UPM1C271MPD6CM provides enhanced ripple current performance (470 mA @ 120 Hz and 635 mA @ 10 kHz) compared to the original specification. The height dimension matches the original part exactly at 0.492" (12.50 mm), eliminating clearance concerns. This component carries AEC-Q200 automotive qualification and is an active product. The slightly higher impedance (140 mOhms versus 120 mOhms) remains within acceptable operating parameters for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can ELXY160ELL271MJC5S be used as a direct replacement for LXY16VB271M10X12LL?

A: Yes. The ELXY160ELL271MJC5S is electrically and mechanically equivalent. The height difference of 0.059" (1.50 mm) must be accommodated within PCB layout constraints. Both components share identical capacitance, voltage rating, tolerance, lead spacing, case diameter, and thermal specifications.

Q: What is the primary difference between the two substitute options?

A: ELXY160ELL271MJC5S is a same-manufacturer equivalent from Chemi-Con with slightly increased height. UPM1C271MPD6CM is a cross-manufacturer upgrade from Nichicon with identical height to the original part and enhanced ripple current performance. Both are active products with automotive qualification.

Q: Are there any compliance differences between the main part and substitutes?

A: The original LXY16VB271M10X12LL is RoHS non-compliant and obsolete. ELXY160ELL271MJC5S is ROHS3 compliant and active. UPM1C271MPD6CM carries AEC-Q200 automotive qualification. Both substitutes provide improved compliance status suitable for modern design requirements.

Q: Does the impedance difference in UPM1C271MPD6CM affect circuit performance?

A: The UPM1C271MPD6CM impedance of 140 mOhms is 20 mOhms higher than the original 120 mOhms specification. This variation is within acceptable parameters for general-purpose applications and does not compromise functional compatibility.

Q: Which substitute is recommended for automotive applications?

A: Both ELXY160ELL271MJC5S and UPM1C271MPD6CM carry AEC-Q200 automotive qualification. Selection depends on PCB clearance availability. If height is constrained, UPM1C271MPD6CM is preferred due to matching original height. If height variation is acceptable, ELXY160ELL271MJC5S provides same-manufacturer continuity.

Q: Can these substitutes be used interchangeably on the same PCB?

A: ELXY160ELL271MJC5S and UPM1C271MPD6CM are not interchangeable without PCB layout modification. The height difference between them (0.059") requires separate footprint consideration. Verify PCB clearance and component placement before selection.
