LKS1J332MESZ Equivalent & Substitute Parts

Part Overview

The LKS1J332MESZ is a 3300 µF, 63 V aluminum electrolytic capacitor manufactured by Nichicon in the LKS series. This radial, can-style snap-in component is designed for audio applications with a rated lifetime of 1000 hours at 85°C and an operating temperature range of -40°C to 85°C. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution for the LKS1J332MESZ is determined by strict equivalence across the following electrical and mechanical parameters:

Capacitance value: 3300 µF (exact match required)
Voltage rating: 63 V (exact match required)
Tolerance: ±20% (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" (10.00 mm) (exact match required)
RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

Two substitute parts meet these criteria: LKS1J332MESC and LKG1J332MESCBK. Both are manufactured by Nichicon and share identical electrical specifications with the main part. Physical dimensions vary within the snap-in can form factor, and ripple current ratings differ based on dimensional variations.

Engineering Selection Recommendations

Both LKS1J332MESC and LKG1J332MESCBK are valid electrical substitutes for the LKS1J332MESZ, as they maintain identical capacitance, voltage rating, tolerance, and operating specifications. All three parts are ROHS3 compliant and classified as obsolete.

Selection between substitutes depends on physical space constraints within the application:

LKS1J332MESC: Smallest height profile at 0.787" (20.00 mm), matching the LKS series form factor. Ripple current rating of 2.45 A @ 120 Hz.
LKG1J332MESCBK: Larger diameter at 1.378" (35.00 mm) with intermediate height of 1.181" (30.00 mm). Higher ripple current rating of 3.15 A @ 120 Hz, providing additional thermal margin in high-ripple applications.

The main part LKS1J332MESZ presents a unique dimensional profile (0.866" diameter, 1.378" height) that does not match either substitute exactly. PCB layout verification is necessary to confirm mechanical fit before component selection.

Frequently Asked Questions (FAQ)

Q: Can LKS1J332MESC or LKG1J332MESCBK be used as direct replacements for LKS1J332MESZ?

A: Both parts are electrical equivalents with identical capacitance, voltage, tolerance, and operating temperature specifications. However, physical dimensions differ. Verify that the selected substitute fits within the available PCB space and mounting hole pattern before implementation.

Q: What is the difference in ripple current between the substitutes?

A: LKG1J332MESCBK is rated for 3.15 A @ 120 Hz, while both LKS1J332MESZ and LKS1J332MESC are rated for 2.45 A @ 120 Hz. The higher ripple current in LKG1J332MESCBK results from its larger physical dimensions, which provide increased surface area for heat dissipation.

Q: Are all three parts RoHS compliant?

A: Yes. LKS1J332MESZ, LKS1J332MESC, and LKG1J332MESCBK are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Why are these parts classified as obsolete?

A: All three components are listed as obsolete by Nichicon. Substitution planning is necessary for long-term design support. Inventory availability varies: LKS1J332MESZ (758 pcs), LKS1J332MESC (1197 pcs), and LKG1J332MESCBK (273,882 pcs).

Q: What parameters must match exactly for substitution?

A: Capacitance (3300 µF), voltage rating (63 V), tolerance (±20%), polarization (polar), package type (radial, can - snap-in), mounting type (through hole), and lead spacing (0.394" / 10.00 mm) must all match exactly. Physical dimensions and ripple current may vary within the allowed form factor.
