TVX1A331MAD Equivalent & Substitute Parts

Part Overview

The TVX1A331MAD is a 330 µF, 10 V aluminum electrolytic capacitor in axial configuration manufactured by Nichicon. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, serving general-purpose applications requiring stable capacitance and ripple current handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TVX1A331MAD is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 10 V (minimum requirement; higher ratings acceptable)
• Tolerance: ±20% (standard tolerance for general-purpose applications)
• Package Configuration: Axial, Can through-hole mounting
• Operating Temperature Range: -40°C to 85°C minimum
• Regulatory Compliance: ROHS3 compliance required

The MAL202134331E3 from Vishay Beyschlag/Draloric/BC Components meets all substitution criteria. While this part exhibits improved specifications in lifetime (2500 hours vs. 2000 hours at 85°C) and lower ESR (1 Ohm), it maintains electrical and mechanical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The MAL202134331E3 is a direct functional substitute for the TVX1A331MAD. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Vishay component carries active product status, ensuring ongoing availability and supply chain stability compared to the obsolete Nichicon part.

Physical dimensions differ slightly: the MAL202134331E3 measures 0.315" diameter × 0.433" length versus the TVX1A331MAD at 0.315" diameter × 0.669" length. This dimensional reduction may require PCB layout verification to confirm clearance compatibility in existing designs.

The ripple current specification of the substitute (276 mA @ 10 kHz) is lower than the original (450 mA @ 10 kHz). Applications requiring the full ripple current capacity of the original part require thermal and electrical load analysis to confirm the substitute's adequacy.

Frequently Asked Questions (FAQ)

Q: Can the MAL202134331E3 replace the TVX1A331MAD in all applications?

A: Electrical substitution is valid for applications within the specified capacitance, voltage, and temperature parameters. Physical dimensions differ; PCB layout compatibility must be confirmed. Ripple current handling differs; thermal performance under load conditions should be evaluated.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The TVX1A331MAD is obsolete, indicating discontinued manufacturing and limited future availability. The MAL202134331E3 is active, ensuring continued supply and manufacturing support. For new designs or long-term production, the active substitute is preferred.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent.

Q: How do the physical dimensions affect substitution?

A: The MAL202134331E3 is shorter (0.433" vs. 0.669" length). Verify PCB hole spacing, component clearance, and mechanical constraints before substitution. The identical 0.315" diameter maintains radial compatibility.

Q: What does the ESR specification mean for substitution?

A: The MAL202134331E3 specifies 1 Ohm ESR, while the TVX1A331MAD does not provide this value. Lower ESR generally indicates better high-frequency performance and reduced heat generation. This represents an improvement in the substitute component.
