LLS2D102MELZ Equivalent & Substitute Parts

Part Overview

The LLS2D102MELZ is a 1000 µF, 200 V aluminum electrolytic capacitor in radial, can snap-in configuration manufactured by Nichicon. This component is rated for 3000 hours at 85°C and operates across -40°C to 85°C. The part is Active status and ROHS3 compliant, designed for general purpose applications requiring high capacitance and voltage ratings in through-hole mounting configurations.

Substitute parts are necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 200 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 3000 Hrs @ 85°C (exact match required)
Operating Temperature: -40°C ~ 85°C (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00mm) (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

All four substitute parts meet these criteria. Physical dimensions (diameter and height) vary within the snap-in form factor, which is permissible as the lead spacing and mounting interface remain constant.

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection between Nichicon (LLS2D102MELA) and Cornell Dubilier Electronics (SLPX series) variants depends on PCB layout constraints and available board space.

The LLS2D102MELA maintains manufacturer continuity with the primary part while offering different physical dimensions. The SLPX series from Cornell Dubilier Electronics provides alternative sourcing with equivalent electrical specifications.

Physical dimension variations among substitutes require verification against PCB footprint and enclosure clearance requirements. Lead spacing remains constant at 0.394" (10.00mm) across all parts, ensuring compatibility with existing through-hole mounting patterns.

Frequently Asked Questions (FAQ)

Q: Can SLPX102M200C4P3, SLPX102M200E5P3, and SLPX102M200H3P3 be used interchangeably with LLS2D102MELZ?

A: Yes. All parts share identical electrical specifications: 1000 µF capacitance, 200 V voltage rating, ±20% tolerance, 3000 hours lifetime at 85°C, and -40°C to 85°C operating range. Physical dimensions differ, requiring PCB layout verification.

Q: What is the difference between LLS2D102MELZ and LLS2D102MELA?

A: Both are Nichicon LLS series parts with identical electrical ratings. The primary difference is physical dimensions: LLS2D102MELZ measures 0.866" diameter × 1.969" height, while LLS2D102MELA measures 0.984" diameter × 1.575" height. Lead spacing remains 0.394" (10.00mm) for both.

Q: Are there differences between the Cornell Dubilier SLPX variants?

A: The SLPX102M200C4P3, SLPX102M200E5P3, and SLPX102M200H3P3 share identical electrical specifications but differ in physical dimensions. SLPX102M200C4P3 is 0.984" diameter × 1.772" height; SLPX102M200E5P3 is 1.181" diameter × 1.378" height; SLPX102M200H3P3 is 1.378" diameter × 1.181" height. All maintain 0.394" (10.00mm) lead spacing.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All parts listed are ROHS3 compliant and maintain Active product status.

Q: What determines whether a part can substitute for LLS2D102MELZ?

A: Substitution requires exact equivalence in capacitance (1000 µF), voltage rating (200 V), tolerance (±20%), lifetime (3000 Hrs @ 85°C), operating temperature (-40°C ~ 85°C), polarization (Polar), mounting type (Through Hole), package type (Radial, Can - Snap-In), and lead spacing (0.394" / 10.00mm). Physical dimensions may vary within the snap-in form factor.
