LLS2A182MELZ Equivalent & Substitute Parts

Part Overview

The LLS2A182MELZ is a 1800 µF, 100 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is rated for 3000 hours at 85°C and operates across the temperature range of -40°C to 85°C. The part is currently active in production with 946 units in stock. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory constraints, or specific performance characteristics within the allowed electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2A182MELZ is determined by strict equivalence across the following parameters:

Capacitance value: 1800 µF (exact match required)
Voltage rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime rating: 3000 Hrs @ 85°C (exact match required)
Operating temperature range: -40°C ~ 85°C (exact match required)
Polarization: Polar (exact match required)
Package type: Radial, Can - Snap-In (exact match required)
Mounting type: Through Hole (exact match required)
Lead spacing: 0.394" (10.00mm) (exact match required)
Compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria. Physical dimensions (diameter and height) may vary within the snap-in package envelope, and ripple current specifications may differ while maintaining functional equivalence.

Engineering Selection Recommendations

All three parts—LLS2A182MELZ, LLS2A182MELA, and SLPX182M100E1P3—are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on physical space constraints and inventory availability:

LLS2A182MELZ (Nichicon): Smallest diameter (22.00mm) and tallest height (42.00mm). Select when radial space is limited but vertical clearance is available.
LLS2A182MELA (Nichicon): Medium diameter (25.00mm) and mid-range height (37.00mm). Select for balanced space requirements within the snap-in envelope.
SLPX182M100E1P3 (Cornell Dubilier Electronics): Largest diameter (30.00mm) but shortest height (25.00mm). Select when vertical space is constrained but radial clearance is available.

All parts maintain identical electrical performance across the specified operating parameters and temperature range.

Frequently Asked Questions (FAQ)

Q: Can LLS2A182MELA be used as a direct replacement for LLS2A182MELZ?

A: Yes. Both parts are Nichicon LLS series capacitors with identical electrical specifications: 1800 µF, 100 V, ±20% tolerance, 3000 Hrs @ 85°C, and snap-in through-hole mounting with 10.00mm lead spacing. Physical dimensions differ; verify PCB layout accommodates the 25.00mm diameter and 37.00mm height of the LLS2A182MELA.

Q: Can SLPX182M100E1P3 from Cornell Dubilier be substituted for the Nichicon LLS2A182MELZ?

A: Yes. The SLPX182M100E1P3 meets all electrical equivalence criteria: 1800 µF, 100 V, ±20% tolerance, 3000 Hrs @ 85°C, snap-in through-hole package, and 10.00mm lead spacing. Physical dimensions differ significantly; the SLPX182M100E1P3 has a 30.00mm diameter and 25.00mm height. Verify PCB layout and mechanical clearances before substitution.

Q: What is the primary difference between these three parts?

A: All three parts are electrically equivalent. The primary differences are physical dimensions (diameter and height) within the snap-in package envelope. Selection depends on available PCB space and mechanical constraints.

Q: Are all three parts RoHS compliant?

A: Yes. LLS2A182MELZ, LLS2A182MELA, and SLPX182M100E1P3 are all ROHS3 compliant and REACH unaffected.

Q: What is the lead spacing for all substitute parts?

A: All three parts have 0.394" (10.00mm) lead spacing, ensuring compatibility with standard through-hole PCB footprints designed for 1800 µF, 100 V snap-in aluminum electrolytic capacitors.
