TVX2G2R2MAD Equivalent & Substitute Parts

Part Overview

The TVX2G2R2MAD is a 2.2 µF, 400 V aluminum electrolytic capacitor in axial configuration manufactured by Nichicon. This component is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement. The part operates across a temperature range of -25°C to 85°C with a rated lifetime of 2000 hours at 85°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Substitute Part Grouping Explanation

Substitution of the TVX2G2R2MAD is determined by the following critical parameters:

• Capacitance value: 2.2 µF (exact match required)
• Tolerance: ±20% (must match or be tighter)
• Voltage rating: Minimum 400 V (equal or higher acceptable)
• Package type: Axial, Can through-hole configuration
• Lifetime specification: 2000 Hrs @ 85°C (minimum requirement)
• Operating temperature range: -25°C ~ 85°C (must encompass or match)
• RoHS3 compliance: Required for regulatory alignment

The substitute part 225TTA450M meets all substitution criteria. It maintains identical capacitance, tolerance, and lifetime specifications while providing a higher voltage rating (450 V), which is acceptable for applications designed for 400 V operation. Both parts share the same axial through-hole package configuration and RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 225TTA450M is a direct functional substitute for the obsolete TVX2G2R2MAD. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The substitute part is currently in active production status, providing supply chain continuity and availability advantages over the obsolete original.

The 450 V rating of the substitute exceeds the 400 V requirement of the original design, presenting no functional limitation for applications operating at or below 400 V. The physical dimension increase (0.394" diameter versus 0.315" diameter) must be verified against PCB layout constraints and mechanical clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 225TTA450M replace the TVX2G2R2MAD in all applications?

A: The 225TTA450M is electrically compatible for applications designed for the TVX2G2R2MAD. Verify mechanical fit, as the substitute has a larger diameter (10.00mm versus 8.00mm). Both parts maintain identical capacitance, tolerance, and lifetime specifications.

Q: What is the significance of the higher voltage rating on the substitute?

A: The 450 V rating on the 225TTA450M provides additional voltage margin for the 400 V application. This is a conservative design practice and does not negatively impact performance in circuits operating at or below 400 V.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: How do the ripple current specifications compare?

A: The 225TTA450M provides 31 mA ripple current at 120 Hz, exceeding the original 28 mA specification. This represents improved performance for low-frequency ripple current handling.

Q: What physical considerations apply to this substitution?

A: The substitute part has a larger can diameter (10.00mm versus 8.00mm) while maintaining the same 21.00mm length. PCB layout and component spacing must accommodate the increased diameter.
