Equivalent & Substitute Parts for ECE-T2VA122EA

Part Overview

The ECE-T2VA122EA is a 1200 µF, 350 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the T-HA series. This radial, can-style snap-in capacitor is designed for general purpose applications requiring high capacitance and voltage ratings. The part is currently obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for direct replacement in existing designs.

• Tolerance: ±20% (exact match required)
• Lifetime: 3000 Hrs @ 105°C (exact match required)
• Operating Temperature: -25°C ~ 105°C (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)
• Case Diameter: 1.378" Dia (35.00mm) (exact match required)

The substitute parts identified below meet all critical electrical specifications and physical form factors. Both alternatives are manufactured by Cornell Dubilier Electronics (CDE) and carry active product status with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both CDE alternatives (381LX122M350A082 and 383LX122M350A082) are qualified substitutes for the obsolete ECE-T2VA122EA based on matching electrical specifications and physical form factors.

The 383LX122M350A082 is the preferred substitute due to its 4-lead configuration, which matches the original ECE-T2VA122EA package specification. This ensures direct compatibility with existing PCB layouts and mounting hardware without modification.

The 381LX122M350A082 is an alternative substitute with equivalent electrical performance. The lead spacing difference (0.394" vs. 0.886") requires verification of PCB hole pattern compatibility before implementation.

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, providing improved regulatory alignment compared to the original part. The slight height increase (82.00mm vs. 80.00mm) must be evaluated for clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 381LX122M350A082 be used as a direct replacement for the ECE-T2VA122EA?

A: The 381LX122M350A082 matches all critical electrical parameters and case diameter. However, the lead spacing differs (0.394" vs. 0.886"), requiring PCB hole pattern compatibility assessment. Physical mounting verification is necessary before implementation.

Q: What is the difference between the two CDE substitutes?

A: Both parts are electrically equivalent with identical capacitance, voltage, tolerance, and lifetime ratings. The primary difference is the lead configuration: the 383LX122M350A082 features a 4-lead snap-in package matching the original design, while the 381LX122M350A082 uses a different lead spacing. The 383LX122M350A082 is recommended for direct replacement applications.

Q: Are there any height clearance concerns with the substitute parts?

A: The substitute parts have a maximum seated height of 3.228" (82.00mm) compared to the original 3.150" (80.00mm). This 0.078" (2.00mm) increase must be evaluated for clearance in confined spaces or under component covers.
