MAL212325331 Equivalent & Substitute Parts

Part Overview

The MAL212325331 is a 330 µF, 16 V aluminum electrolytic capacitor in axial configuration, manufactured by Vishay Beyschlag/Draloric/BC Components as part of the 123 SAL-A series. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates across a temperature range of -55°C to 125°C with a rated lifetime of 20,000 hours at 125°C, serving general-purpose applications requiring stable capacitance and low equivalent series resistance.

Substitute Part Grouping Explanation

Substitution of the MAL212325331 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Axial, Can through-hole (exact match required)
• Polarization: Polar (exact match required)

The substitute part 337TTA016M meets all primary electrical specifications. However, differences exist in secondary performance characteristics including ESR measurement frequency, lifetime rating at temperature, operating temperature range, ripple current capacity, and physical dimensions. These differences must be evaluated within the context of the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 337TTA016M serves as an active substitute for the obsolete MAL212325331, offering equivalent primary electrical specifications with improved regulatory compliance. The substitute part achieves ROHS3 compliance and REACH unaffected status, addressing modern environmental and regulatory requirements that the original part does not meet.

Physical dimensions differ significantly, with the 337TTA016M measuring smaller in both diameter and length. This dimensional reduction may require PCB layout modification to accommodate the substitute component within existing mounting footprints.

The substitute part exhibits reduced performance in secondary characteristics: operating temperature range is limited to -40°C to 85°C compared to the original -55°C to 125°C specification, lifetime rating is reduced to 2,000 hours at 85°C versus 20,000 hours at 125°C, and ripple current capacity is lower at 320 mA versus 510 mA. These reductions must be evaluated against application-specific thermal and electrical stress conditions.

Frequently Asked Questions (FAQ)

Q: Can the 337TTA016M be used as a direct replacement for the MAL212325331?

A: The 337TTA016M matches the primary electrical specifications of capacitance, voltage rating, tolerance, and package type. However, physical dimensions differ, requiring PCB layout assessment. Secondary performance parameters including temperature range, lifetime rating, and ripple current capacity are reduced and must be evaluated for application compatibility.

Q: What are the key differences between these parts?

A: Primary electrical specifications are equivalent. The substitute part is physically smaller, operates over a narrower temperature range (-40°C to 85°C versus -55°C to 125°C), has a reduced lifetime rating at temperature, and lower ripple current capacity. The substitute achieves superior regulatory compliance with ROHS3 and REACH unaffected status.

Q: Are there physical space constraints with the substitute part?

A: Yes. The 337TTA016M measures 0.315" diameter by 0.630" length, compared to the original 0.406" diameter by 1.260" length. The substitute is significantly smaller and may not fit existing PCB mounting holes or clearance envelopes designed for the original component.

Q: How do the temperature operating ranges compare?

A: The MAL212325331 operates from -55°C to 125°C, while the 337TTA016M operates from -40°C to 85°C. Applications requiring operation below -40°C or above 85°C cannot use the substitute part.

Q: What is the significance of the RoHS and REACH compliance differences?

A: The substitute part achieves ROHS3 compliance and REACH unaffected status, meeting current environmental regulations. The original part is RoHS non-compliant and REACH affected, which may restrict its use in regulated markets or applications with environmental compliance requirements.
