Key Parameters

Substitute Part Grouping Explanation

Substitution of the TVX1E331MAD is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Axial, Can through-hole (exact match required)
• Operating temperature range: -40°C ~ 85°C (minimum requirement)
• Physical dimensions: Compatible with 8.00mm diameter specification

The MAL202136331E3 from Vishay Beyschlag/Draloric/BC Components meets all substitution criteria. While this substitute exhibits improved electrical characteristics (680 mOhm ESR, 2500-hour lifetime at 85°C versus 2000 hours), it maintains full compatibility with the original part's electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAL202136331E3 is an active product with full ROHS3 compliance and REACH unaffected status, providing long-term availability and regulatory alignment. The substitute part delivers equivalent electrical performance across all critical parameters while offering extended operational lifetime at elevated temperatures. Both components maintain identical voltage and capacitance specifications, ensuring direct functional compatibility in general-purpose applications.

The physical dimension difference (0.827" versus 0.709" length) must be evaluated against available board space in the target application. The substitute's shorter axial length may provide layout advantages in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can MAL202136331E3 be used as a direct replacement for TVX1E331MAD?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), and through-hole axial package configuration. Operating temperature ranges and compliance certifications are equivalent.

Q: What is the significance of the lifetime difference (2000 Hrs vs. 2500 Hrs)?

A: The substitute part provides 500 additional hours of rated lifetime at 85°C. This represents improved reliability margin but does not affect functional compatibility in applications designed for the original 2000-hour specification.

Q: Does the physical dimension difference affect compatibility?

A: The substitute is 0.118" (3.00mm) shorter in axial length. PCB layout and component spacing must accommodate this dimension. The 8.00mm diameter remains identical, ensuring lead hole compatibility.

Q: Are there compliance or supply chain advantages to using the substitute?

A: The MAL202136331E3 is an active product with established supply channels, whereas the TVX1E331MAD is obsolete. The substitute maintains ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for new designs and ongoing production.

Q: What ripple current specifications apply when selecting between these parts?

A: The original part supports 570 mA ripple current at 10 kHz. The substitute supports 442 mA at 10 kHz. Applications requiring ripple current handling above 442 mA must evaluate the substitute's capability against circuit requirements.
