Equivalent & Substitute Parts for TVX2A221MCD

Part Overview

The Nichicon TVX2A221MCD is a 220 µF, 100 V aluminum electrolytic capacitor in axial, can package configuration. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement. The TVX series has been discontinued, requiring engineers to source functionally equivalent alternatives from active product lines that maintain the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TVX2A221MCD are qualified based on the following electrical and mechanical parameters:

Core Matching Criteria:

• Capacitance: 220 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Axial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
• RoHS3 Compliance: Required

Acceptable Variation Parameters:

• Lifetime @ 85°C: Equal to or greater than 2000 hours
• Ripple Current Ratings: Equal to or greater than specified values
• Physical Dimensions: Minor variations acceptable within industry standards for axial can packages
• ESR (Equivalent Series Resistance): Lower values indicate improved performance

Two substitute parts meet these criteria and are sourced from active product lines.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the TVX2A221MCD.

227TTA100M (Cornell Dubilier / Illinois Capacitor): This part maintains identical electrical specifications to the original component, including 2000-hour lifetime at 85°C and 560 mA ripple current at 120 Hz. The axial can package dimensions are nearly identical (26.00mm length versus 28.00mm original), ensuring compatibility with existing PCB layouts. Product status is active with established supply chain availability. RoHS3 compliance and REACH unaffected status are confirmed.

MAL202119221E3 (Vishay Beyschlag/Draloric/BC Components): This part exceeds the original specifications with an extended 8000-hour lifetime at 85°C, providing enhanced reliability margin. ESR is lower at 610 mOhm compared to the Cornell Dubilier substitute at 754 mOhm, indicating superior high-frequency performance characteristics. Physical dimensions show minor variation (30.00mm length), which may require PCB layout verification for space-constrained applications. Product status is active with confirmed supply availability. RoHS3 compliance and REACH unaffected status are confirmed.

Both parts are sourced from manufacturers with established quality certifications and active product lines, ensuring long-term availability and consistent supply.

Frequently Asked Questions (FAQ)

Q: Can the 227TTA100M and MAL202119221E3 be used interchangeably with the TVX2A221MCD?

A: Both parts meet the core electrical specifications (220 µF, 100 V, ±20% tolerance) and package requirements (axial, can, through-hole). Physical dimensions show minor variations within acceptable tolerances for axial can packages. Verification of PCB layout clearance is recommended, particularly for the MAL202119221E3 due to its 30.00mm length.

Q: What is the significance of the lifetime rating difference between the substitutes?

A: The TVX2A221MCD and 227TTA100M are both rated for 2000 hours at 85°C. The MAL202119221E3 provides 8000 hours at 85°C, representing a 4x improvement in thermal life expectancy. This extended rating provides additional reliability margin in applications subject to sustained elevated temperatures.

Q: How do ESR values affect component selection?

A: ESR (Equivalent Series Resistance) impacts ripple current handling and heat dissipation. The MAL202119221E3 exhibits lower ESR (610 mOhm) compared to the 227TTA100M (754 mOhm), resulting in improved performance in high-frequency ripple current applications. For general-purpose applications, both values are acceptable.

Q: Are there any compliance or certification differences between the substitutes?

A: All three parts (original and both substitutes) are ROHS3 compliant and REACH unaffected. Both substitute parts are sourced from active product lines with established quality certifications, ensuring consistent compliance with regulatory requirements.

Q: What should be considered when selecting between the two substitute options?

A: Selection should be based on application requirements and PCB layout constraints. The 227TTA100M provides a direct specification match with minimal dimensional variation. The MAL202119221E3 offers enhanced thermal life and lower ESR, suitable for applications requiring extended operational life or improved high-frequency performance. Physical dimensions should be verified against available PCB space.
