LKS1K472MESA Equivalent & Substitute Parts

Part Overview

The LKS1K472MESA is a 4700 µF, 80 V aluminum electrolytic capacitor manufactured by Nichicon in the LKS series. This radial, can-style snap-in capacitor is rated for 1000 hours at 85°C and is designed for audio applications. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring compatible electrical and mechanical characteristics.

Substitute Part Grouping Explanation

Substitution for the LKS1K472MESA is determined by strict equivalence in the following parameters:

Capacitance: 4700 µF (exact match required)
Voltage Rating: 80 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)
Operating Temperature Range: -40°C ~ 85°C (exact match required)

Two substitute parts meet these criteria:

LKG1K472MESCBK (Nichicon, LKG series) - Direct equivalent with identical electrical and mechanical specifications
SLPX472M080C9P3 (Cornell Dubilier Electronics, SLPX series) - Functional upgrade with enhanced performance characteristics

Engineering Selection Recommendations

LKG1K472MESCBK provides direct functional equivalence to the LKS1K472MESA. Both parts are Nichicon products with identical electrical ratings and operating parameters. The primary difference is the increased can diameter (35.00mm vs 25.00mm), which may require PCB layout verification. Both parts are obsolete and ROHS3 compliant.

SLPX472M080C9P3 is an active product from Cornell Dubilier Electronics that meets all electrical and mechanical substitution criteria. This part offers extended lifetime (3000 hours at 85°C versus 1000 hours), specified ESR characteristics (71 mOhm @ 120 Hz), and higher ripple current capability. The SLPX472M080C9P3 maintains identical lead spacing, height, and mounting type, with matching can diameter to the original LKS1K472MESA. Active product status ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can LKG1K472MESCBK be used as a direct replacement for LKS1K472MESA?

A: Yes. Both parts share identical capacitance (4700 µF), voltage rating (80 V), tolerance (±20%), package type (radial snap-in), lead spacing (10.00mm), height (50.00mm), and operating temperature range (-40°C ~ 85°C). The increased can diameter (35.00mm vs 25.00mm) requires verification that the PCB layout accommodates the larger physical footprint.

Q: What are the advantages of SLPX472M080C9P3 over the original LKS1K472MESA?

A: The SLPX472M080C9P3 offers three key advantages: extended lifetime (3000 hours at 85°C versus 1000 hours), specified ESR characteristics (71 mOhm @ 120 Hz), and active product status ensuring supply availability. Electrical ratings and mechanical dimensions remain compatible with the original part.

Q: Are there physical footprint differences between these parts?

A: Yes. The LKG1K472MESCBK has a larger can diameter (35.00mm) compared to both the LKS1K472MESA and SLPX472M080C9P3 (25.00mm). Lead spacing (10.00mm) and height (50.00mm) are identical across all three parts. PCB layout must accommodate the larger diameter if using the LKG variant.

Q: Do all three parts meet RoHS compliance?

A: Yes. LKS1K472MESA, LKG1K472MESCBK, and SLPX472M080C9P3 are all ROHS3 compliant.

Q: Which part should be selected for new designs?

A: SLPX472M080C9P3 is recommended for new designs due to active product status, extended lifetime rating, and specified ESR characteristics. This ensures long-term supply chain availability and improved performance margins.
