Substitute Part Grouping Explanation

Substitution for the LKS1V822MESA is determined by strict equivalence in the following parameters:

Capacitance: 8200 µF (exact match required)
Voltage Rating: 35 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" (10.00mm) (exact match required)

Substitute parts are grouped into two categories:

Direct Equivalents (Same Series): Parts that maintain identical electrical and mechanical specifications within the same manufacturer series.

Upgraded Alternatives (Different Manufacturer): Parts from alternative manufacturers that meet or exceed the electrical specifications while maintaining mechanical compatibility.

Engineering Selection Recommendations

LKG1V822MESBBK (Nichicon LKG Series): This part maintains electrical equivalence with the LKS1V822MESA while offering increased ripple current capacity (3.6 A vs. 2.7 A at 120 Hz). However, physical dimensions differ: the LKG variant has a larger diameter (1.181" vs. 0.984") and greater height (1.575" vs. 1.378"). PCB layout verification is required before substitution. Both parts are obsolete with ROHS3 compliance.

LKS1V822MESY (Nichicon LKS Series): This part is electrically identical to the LKS1V822MESA with matching ripple current (2.7 A at 120 Hz) and identical operating specifications. Physical dimensions differ in diameter (0.787" vs. 0.984") and height (1.969" vs. 1.378"). This represents a direct series equivalent with different form factor. Both parts are obsolete with ROHS3 compliance.

SLPX822M035C5P3 (Cornell Dubilier Electronics SLPX Series): This part is an upgraded alternative with extended lifetime (3000 Hrs @ 85°C vs. 1000 Hrs), higher ripple current capacity (3.33 A at 120 Hz and 4.16 A at 20 kHz), and specified ESR (65 mOhm @ 120 Hz). Physical dimensions match the LKS1V822MESA exactly (0.984" diameter, 1.378" height). This part is currently active in production with ROHS3 compliance, providing long-term availability and improved performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can LKG1V822MESBBK be used as a direct replacement for LKS1V822MESA?

A: Electrical substitution is possible due to matching capacitance, voltage, tolerance, and operating temperature specifications. However, physical dimensions differ significantly. The LKG variant is larger in both diameter and height. PCB layout and mechanical clearance must be verified before implementation.

Q: What is the primary advantage of SLPX822M035C5P3 over the original LKS1V822MESA?

A: The SLPX822M035C5P3 offers three times the rated lifetime (3000 Hrs vs. 1000 Hrs at 85°C), higher ripple current capacity, and is currently in active production. Physical dimensions are identical, enabling direct mechanical compatibility. ESR specification is provided, enabling precise circuit analysis.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The LKS1V822MESA, LKG1V822MESBBK, LKS1V822MESY, and SLPX822M035C5P3 are all ROHS3 compliant.

Q: Does lead spacing remain constant across all substitute options?

A: Yes. All parts maintain 0.394" (10.00mm) lead spacing, ensuring PCB footprint compatibility.

Q: Which substitute part offers the best long-term availability?

A: The SLPX822M035C5P3 is the only part with active production status. The LKS1V822MESA, LKG1V822MESBBK, and LKS1V822MESY are all obsolete.

Q: Can physical dimension differences affect circuit performance?

A: Physical dimensions do not affect electrical performance. However, larger dimensions may impact PCB layout, thermal management, and mechanical assembly. Verify available space before substitution.
