Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LKX2D471MESY45 are classified into two categories based on electrical and mechanical compatibility:

Upgrade Substitute: LGN2P471MELY45 provides higher voltage rating (220 V vs. 200 V) and extended lifetime (3000 Hrs @ 105°C vs. 2000 Hrs @ 105°C) while maintaining identical capacitance (470 µF), tolerance (±20%), lead spacing (10.00 mm), and physical dimensions (0.787" Dia, 1.850" Height). This part is suitable for applications requiring enhanced voltage margin and reliability.

Similar Substitute: LKX2D471MESZ35 maintains identical electrical specifications (470 µF, 200 V, ±20%, 2000 Hrs @ 105°C) and lead spacing (10.00 mm) but differs in physical dimensions (0.866" Dia, 1.457" Height). This part is suitable for space-constrained applications where the smaller height profile is advantageous.

Substitution eligibility is determined by: capacitance value, voltage rating (equal or higher), tolerance, lead spacing, mounting type, and package configuration. All substitute parts maintain ROHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

LGN2P471MELY45 (Upgrade Substitute): Select this part when higher voltage margin and extended operational lifetime are required. The 220 V rating provides 10% additional voltage headroom compared to the 200 V main part, and the 3000-hour lifetime at 105°C extends component reliability by 50%. This part is suitable for applications where thermal stress or voltage transients are concerns. All compliance certifications (ROHS3, REACH unaffected) are maintained.

LKX2D471MESZ35 (Similar Substitute): Select this part when board space constraints require a lower profile component. The 1.457" seated height reduces vertical clearance requirements by 0.393" compared to the main part, while maintaining identical electrical performance and voltage rating. Lead spacing and mounting type remain unchanged, ensuring direct PCB compatibility. All compliance certifications are maintained.

Both substitute parts are active products from Nichicon with full regulatory compliance. Selection should be based on specific application requirements: voltage margin needs, thermal environment, and physical space availability.

Frequently Asked Questions (FAQ)

Q: Can LGN2P471MELY45 be used as a direct replacement for LKX2D471MESY45?

A: Yes. LGN2P471MELY45 is electrically and mechanically compatible. It maintains the same capacitance (470 µF), tolerance (±20%), lead spacing (10.00 mm), and physical footprint (0.787" Dia, 1.850" Height). The higher voltage rating (220 V vs. 200 V) and extended lifetime (3000 Hrs vs. 2000 Hrs @ 105°C) make it a suitable upgrade substitute.

Q: Can LKX2D471MESZ35 be used as a direct replacement for LKX2D471MESY45?

A: Yes, with space consideration. LKX2D471MESZ35 is electrically identical and maintains the same lead spacing (10.00 mm). However, it has a smaller physical profile (0.866" Dia, 1.457" Height vs. 0.787" Dia, 1.850" Height). Verify that the reduced height does not conflict with board layout or component clearance requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: capacitance value (must be identical), voltage rating (equal or higher), tolerance (must be identical), lead spacing (must be identical), mounting type (must be identical), and package configuration (must be identical). All substitute parts must maintain ROHS3 compliance and REACH unaffected status.

Q: Are there voltage derating considerations when using LGN2P471MELY45 in a 200 V circuit?

A: No. LGN2P471MELY45 is rated for 220 V operation, which exceeds the 200 V circuit requirement. The part operates safely at or below its rated voltage.

Q: What is the difference between the LKX and LGN series?

A: Both are Nichicon aluminum electrolytic capacitors. The LKX series is specified for audio applications with 2000-hour lifetime at 105°C. The LGN series is specified for general purpose applications with extended 3000-hour lifetime at 105°C. Electrical and mechanical specifications are otherwise compatible for the identified substitute parts.
