LNT1A334MSE Equivalent & Substitute Parts

Part Overview

The LNT1A334MSE is a 330000 µF aluminum electrolytic capacitor rated at 10 V with screw terminals, manufactured by Nichicon in the LNT series. This component is designed for general-purpose applications requiring high capacitance in a chassis-mount radial can configuration. The part is currently active in production with 1035 units in stock.

Substitute parts are identified when equivalent capacitance and mechanical compatibility are maintained while allowing for rated voltage upgrades or alternative sourcing within the same product family.

Substitute Part Grouping Explanation

Substitution for the LNT1A334MSE is based on the following criteria:

• Capacitance: Must remain 330000 µF (no tolerance variation permitted for substitution)
• Package / Case: Must be Radial, Can - Screw Terminals
• Mechanical Compatibility: Lead spacing, diameter, and height must match exactly
• Voltage Rating: Upgrades to higher voltage ratings are permissible when all other parameters remain constant
• Series Family: Parts must belong to the Nichicon LNT series
• Compliance: RoHS3 compliance and REACH status must be maintained

The LNT1C334MSE qualifies as a substitute because it maintains identical capacitance, tolerance, mechanical dimensions, lead spacing, mounting type, and compliance certifications while providing an upgraded voltage rating of 16 V.

Parameter Comparison

Engineering Selection Recommendations

The LNT1C334MSE is a direct substitute for the LNT1A334MSE in applications where the circuit design permits operation at the higher 16 V rating. Both parts maintain identical mechanical form factors, thermal characteristics, and regulatory compliance. The substitute part is suitable for direct replacement in existing designs without PCB or mechanical modifications.

Selection between the main part and substitute should be based on circuit voltage requirements. The 16 V rated substitute provides additional voltage margin and is compatible with all mechanical and electrical interfaces of the original specification.

Frequently Asked Questions (FAQ)

Q: Can the LNT1C334MSE replace the LNT1A334MSE in any application?

A: The LNT1C334MSE is mechanically and electrically compatible with the LNT1A334MSE. Substitution is valid when the circuit design operates at or below 16 V. The higher voltage rating of the substitute does not affect performance in lower-voltage applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical lead spacing (1.252" / 31.80mm), diameter (3.000" / 76.20mm), and maximum seated height (4.843" / 123.00mm). No mechanical modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LNT1A334MSE and LNT1C334MSE are ROHS3 compliant and REACH affected, meeting identical regulatory requirements.

Q: What is the difference in ripple current handling between these parts?

A: The LNT1C334MSE exhibits higher ripple current ratings due to its elevated voltage rating. At 120 Hz, the substitute handles 20.6 A compared to 15.8 A for the main part. At 10 kHz, the substitute handles 23.69 A compared to 18.17 A for the main part.

Q: Are both parts currently available?

A: Yes. The LNT1A334MSE has 1035 units in stock, and the LNT1C334MSE has 697 units in stock, both listed as active products.
