LLS1E153MELZ Equivalent & Substitute Parts

Part Overview

The LLS1E153MELZ is a 15000 µF, 25 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is classified as Active product status and is designed for general purpose applications requiring high capacitance energy storage in compact form factors. The need for equivalent and substitute parts arises from supply chain considerations, inventory availability, and design flexibility across manufacturing batches and alternative qualified suppliers.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1E153MELZ is determined by strict equivalence across the following parameters: capacitance value (15000 µF), voltage rating (25 V), tolerance (±20%), lifetime specification (3000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (0.394" / 10.00mm), mounting type (Through Hole), and package configuration (Radial, Can - Snap-In). All substitute parts listed maintain these core electrical and mechanical specifications. Physical dimensions (diameter and height) may vary within the snap-in package family while preserving PCB footprint compatibility through standardized lead spacing. RoHS3 compliance and REACH unaffected status are maintained across all listed alternatives.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection between Nichicon LLS series and Cornell Dubilier Electronics SLPX series components is based on supply availability and inventory position. The LLS1E153MELA variant offers reduced physical height (1.654" vs 2.047") while maintaining identical electrical specifications. The SLPX153M025A9P3 and SLPX153M025C7P3 variants from CDE provide equivalent electrical performance with documented ESR specifications (40mOhm @ 120Hz) and are available in both compact (22.00mm diameter) and standard (25.00mm diameter) form factors. Physical dimension variations across the snap-in package family do not affect PCB compatibility due to standardized 10.00mm lead spacing. Component selection should prioritize availability and lead time requirements while confirming PCB layout accommodates the selected physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can LLS1E153MELA be used as a direct replacement for LLS1E153MELZ? A: Yes. Both components share identical electrical specifications: 15000 µF capacitance, 25 V rating, ±20% tolerance, 3000 Hrs @ 85°C lifetime, and -40°C ~ 85°C operating range. The primary difference is physical height (1.654" vs 2.047"), which may require PCB layout verification for clearance constraints.

Q: Are Cornell Dubilier SLPX parts compatible with Nichicon LLS positions? A: Yes, when lead spacing is 10.00mm. All four parts maintain identical lead spacing and snap-in package configuration. Physical diameter and height variations require confirmation that PCB layout accommodates the selected form factor.

Q: What is the significance of the ESR specification on SLPX parts? A: The SLPX series provides documented ESR values (40mOhm @ 120Hz), whereas ESR data is not specified for the LLS series in this reference. ESR affects ripple current handling and thermal performance in high-frequency applications. Both series meet the same ripple current requirements at 120 Hz and 50 kHz / 20 kHz respectively.

Q: Do all substitute parts meet the same compliance requirements? A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards for the LLS1E153MELZ application.

Q: What determines whether a part can substitute for LLS1E153MELZ? A: Substitution requires matching capacitance (15000 µF), voltage rating (25 V), tolerance (±20%), lifetime (3000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (10.00mm), mounting type (Through Hole), and package style (Radial, Can - Snap-In). Physical dimensions may vary within these constraints.
