MAL212384331 Equivalent & Substitute Parts

Part Overview

The MAL212384331 is a 330 µF, 10 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 substitutes necessary 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAL212384331 is determined by the following critical parameters:

• Capacitance value must equal 330 µF
• Tolerance must be ±20% or tighter
• Voltage rating must be equal to or greater than 10 V
• Package configuration must be axial, can-style through-hole
• Polarization must remain polar
• Operating temperature range must encompass -55°C to 125°C

The MAL211817331E3 qualifies as a substitute based on matching capacitance (330 µF), tolerance (±20%), polarization (polar), package type (axial, can), mounting method (through hole), and operating temperature range (-55°C to 125°C). The substitute features a higher voltage rating (40 V), which provides additional design margin and is acceptable for direct replacement in circuits designed for 10 V operation.

Parameter Comparison

Engineering Selection Recommendations

The MAL211817331E3 is suitable for direct substitution of the MAL212384331 in applications where the circuit voltage rating does not exceed 10 V. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability. The MAL211817331E3 achieves RoHS3 compliance, addressing regulatory requirements that may not be met by the obsolete, non-compliant original part.

Differences in ESR (1.1 Ohm versus 430 mOhm) and lifetime rating (20,000 hours versus 8,000 hours at 125°C) should be evaluated against specific application requirements. The substitute's lower ESR and higher voltage rating provide improved electrical performance characteristics for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the MAL211817331E3 replace the MAL212384331 in all applications?

A: The MAL211817331E3 is electrically compatible for circuits operating at or below 10 V. Both parts share identical capacitance (330 µF), tolerance (±20%), operating temperature range (-55°C to 125°C), and through-hole axial package configuration. The substitute's higher voltage rating (40 V) does not prevent its use in 10 V circuits.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (10 V versus 40 V), ESR (1.1 Ohm versus 430 mOhm), lifetime at 125°C (20,000 hours versus 8,000 hours), and product status (obsolete versus active). The substitute features improved ESR performance and RoHS3 compliance.

Q: Are the physical dimensions compatible?

A: Both parts use axial, can-style through-hole packages. The MAL212384331 measures 0.406" diameter × 1.260" length (10.30 mm × 32.00 mm), while the MAL211817331E3 measures 0.492" diameter × 1.181" length (12.50 mm × 30.00 mm). PCB layout and mechanical clearance must be verified for the substitute part.

Q: Does the substitute meet current compliance standards?

A: The MAL211817331E3 is RoHS3 compliant and REACH unaffected, whereas the original MAL212384331 is RoHS non-compliant and REACH affected. The substitute meets current regulatory requirements for new designs and production.

Q: What is the impact of the lower lifetime rating on the substitute part?

A: The MAL211817331E3 has an 8,000-hour lifetime at 125°C compared to the original part's 20,000-hour rating. Application-specific reliability requirements must be assessed to determine if this difference affects system performance or maintenance intervals.
