Substitute Part Grouping Explanation

Substitution eligibility for the LKX2D471MESA30 is determined by the following criteria:

Primary Compatibility Parameters:

Capacitance value: 470 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead spacing: 0.394" (10.00 mm) (exact match required)
Package type: Radial, Can - Snap-In (exact match required)
Mounting type: Through Hole (exact match required)

Secondary Compatibility Parameters (allowable variation):

Voltage rating: Equal to or greater than 200 V
Lifetime @ temperature: Equal to or greater than 2000 Hrs @ 105°C
Physical dimensions (diameter, height): Equal to or less than original dimensions, or functionally equivalent within board layout constraints
ESR and ripple current: May vary based on application requirements

Substitute parts are grouped into two categories: upgrade parts (higher voltage rating or extended lifetime) and similar parts (same voltage rating with dimensional or performance variations).

Engineering Selection Recommendations

LGG2E471MELA30 (Upgrade Option)

This part is suitable as an upgrade substitute where higher voltage margin is required. The 250 V rating provides increased safety margin over the 200 V specification of the original part. Both parts share identical physical dimensions (0.984" diameter, 1.260" height), lead spacing, and mounting configuration. Both are ROHS3 compliant and active in production. The LGG2E471MELA30 has higher inventory availability (5405 units). This part is appropriate for applications where voltage stress reduction is a design objective.

LKX2D471MESZ35 (Similar Option - Dimensional Variation)

This part maintains the same voltage rating (200 V), capacitance (470 µF), and lead spacing as the original. It differs in physical dimensions: smaller diameter (0.866" vs. 0.984") but greater height (1.457" vs. 1.260"). This configuration may be suitable for space-constrained applications where vertical clearance is available but horizontal board space is limited. Both are Nichicon LKX series components with identical electrical performance characteristics. This part is active in production with 775 units in stock.

381LR471M200J022 (Similar Option - Extended Lifetime)

This Cornell Dubilier Electronics part matches the original in voltage rating (200 V), capacitance (470 µF), physical dimensions, and lead spacing. It provides extended lifetime (3000 Hrs @ 105°C vs. 2000 Hrs), higher ripple current capability (1.85 A @ 120 Hz vs. 1.48 A), and specified ESR (317 mOhm @ 120 Hz). This part is ROHS3 compliant and has the highest inventory availability (8379 units). Selection of this part is appropriate where extended operational life or higher ripple current handling is required.

Frequently Asked Questions (FAQ)

Q: Can LGG2E471MELA30 be used as a direct replacement for LKX2D471MESA30?

A: Yes, with the understanding that it provides a higher voltage rating (250 V vs. 200 V). Physical dimensions, lead spacing, and mounting type are identical. The higher voltage rating does not create compatibility issues in circuits designed for 200 V operation.

Q: What is the primary difference between LKX2D471MESZ35 and the original part?

A: The LKX2D471MESZ35 has different physical dimensions: smaller diameter (22.00 mm vs. 25.00 mm) but greater height (37.00 mm vs. 32.00 mm). Electrical specifications, voltage rating, and capacitance are identical. Board layout constraints determine suitability.

Q: Why does 381LR471M200J022 have a longer lifetime rating?

A: The 381LR471M200J022 is rated for 3000 hours at 105°C compared to 2000 hours for the original part. This reflects different internal construction and materials used by Cornell Dubilier Electronics. The extended lifetime may support applications requiring longer service intervals.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—LKX2D471MESA30, LGG2E471MELA30, LKX2D471MESZ35, and 381LR471M200J022—are ROHS3 compliant.

Q: What is the significance of lead spacing in substitution?

A: Lead spacing (0.394" / 10.00 mm) is a critical parameter for through-hole mounting. All substitute parts maintain this spacing, ensuring compatibility with existing PCB footprints without modification.

Q: Can physical dimension differences affect circuit performance?

A: Physical dimensions do not affect electrical performance. However, they impact board layout feasibility. Verify that alternative dimensions fit within available board space before selection.

Q: Which substitute part has the best availability?

A: The 381LR471M200J022 has the highest inventory (8379 units), followed by LGG2E471MELA30 (5405 units). Availability may vary by distributor and time.
