TVX1H331MCD Equivalent & Substitute Parts

Part Overview

The TVX1H331MCD is a 330 µF, 50 V aluminum electrolytic capacitor in axial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part is rated for 2000 hours at 85°C and is suitable for general-purpose applications requiring through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TVX1H331MCD is determined by the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: Minimum 50 V (equal or higher voltage rating is acceptable)
• Tolerance: ±20% (standard tolerance for aluminum electrolytic capacitors)
• Package configuration: Axial, can format with through-hole mounting
• Operating temperature range: -40°C ~ 85°C (minimum requirement)
• RoHS3 compliance: Required for regulatory alignment

Two substitute parts meet these criteria with varying degrees of parameter alignment. The 337TTA050M provides a direct voltage match at 50 V, while the MAL202118331E3 offers an elevated voltage rating of 63 V with extended lifetime characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 337TTA050M is the primary direct substitute for the TVX1H331MCD. Both parts share identical voltage ratings (50 V), capacitance values (330 µF), physical dimensions (10.00mm x 26.00mm), and lifetime specifications (2000 Hrs @ 85°C). The 337TTA050M is currently in active production status with ROHS3 compliance and equivalent ripple current performance at 120 Hz (565 mA versus 560 mA).

The MAL202118331E3 serves as an alternative substitute with the following considerations: it maintains the same capacitance and tolerance but operates at a higher voltage rating of 63 V, providing additional voltage margin. The MAL202118331E3 offers extended lifetime (8000 Hrs @ 85°C) and comparable ripple current performance at 10 kHz (854 mA versus 840 mA). However, the physical dimensions are larger (12.50mm x 30.00mm), which may require PCB layout verification for space-constrained applications.

Both substitute parts maintain ROHS3 compliance and operate within the required temperature range of -40°C ~ 85°C.

Frequently Asked Questions (FAQ)

Q: Can the 337TTA050M be used as a direct replacement for the TVX1H331MCD?

A: Yes. The 337TTA050M matches the TVX1H331MCD in capacitance (330 µF), voltage rating (50 V), tolerance (±20%), physical dimensions (10.00mm x 26.00mm), lifetime (2000 Hrs @ 85°C), and mounting configuration (through-hole axial). Both parts are ROHS3 compliant.

Q: What is the primary difference between the 337TTA050M and MAL202118331E3?

A: The 337TTA050M provides a direct parameter match at 50 V with identical physical dimensions. The MAL202118331E3 operates at 63 V (higher voltage rating) with extended lifetime (8000 Hrs @ 85°C) but has larger physical dimensions (12.50mm x 30.00mm versus 10.00mm x 26.00mm).

Q: Can the MAL202118331E3 be used in place of the TVX1H331MCD?

A: The MAL202118331E3 is electrically compatible as a substitute, maintaining the same capacitance and tolerance. The higher voltage rating (63 V) is acceptable for circuits designed for 50 V operation. However, the larger physical dimensions require verification that the PCB layout can accommodate the increased size.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both the 337TTA050M and MAL202118331E3 are ROHS3 compliant, matching the compliance status of the TVX1H331MCD.

Q: What is the impact of the different lifetime ratings?

A: The TVX1H331MCD and 337TTA050M are both rated for 2000 Hrs @ 85°C. The MAL202118331E3 offers 8000 Hrs @ 85°C, providing extended operational life in high-temperature environments. Selection depends on application requirements and expected service duration.
