MAL212367228 Equivalent & Substitute Parts

Part Overview

The MAL212367228 is a 2.2 µF, 40 V aluminum electrolytic capacitor in axial configuration manufactured by Vishay Beyschlag/Draloric/BC Components. 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 ESR characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAL212367228 is determined by the following critical parameters:

• Capacitance Value: 2.2 µF (exact match required)
• Tolerance: ±20% (must match or be tighter)
• Voltage Rating: Minimum 40 V (equal or higher acceptable)
• Package Configuration: Axial, Can through-hole mounting
• Polarization: Polar (aluminum electrolytic)

The substitute part 225TTA050M meets these core electrical and mechanical requirements. It maintains identical capacitance and tolerance specifications while providing a higher voltage rating (50 V), which is acceptable for direct substitution in circuits designed for 40 V operation. Both parts utilize axial through-hole mounting and polar aluminum electrolytic construction.

Parameter Comparison

Engineering Selection Recommendations

The 225TTA050M is a suitable substitute for the MAL212367228 based on the following factors:

Electrical Compatibility: Both parts share identical capacitance (2.2 µF) and tolerance (±20%) specifications. The substitute's higher voltage rating (50 V vs. 40 V) is acceptable for applications designed around the original 40 V specification, as higher-rated capacitors operate safely at lower voltages.

Product Status: The MAL212367228 is obsolete, while the 225TTA050M is active and maintains current manufacturing support and inventory availability (10,078 pcs in stock vs. 922 pcs for the original part).

Compliance: The 225TTA050M is ROHS3 compliant, whereas the original part is RoHS non-compliant. This substitution improves regulatory compliance for new designs and production runs.

Physical Considerations: The substitute part is physically smaller (5.00mm x 13.00mm vs. 6.70mm x 15.30mm), which may require PCB layout verification to ensure proper fit within existing mounting footprints.

Thermal and Ripple Performance: The substitute exhibits lower ESR (90.43 Ohm vs. 109 Ohm) and higher ripple current capability (23 mA @ 120 Hz vs. 11 mA @ 100 Hz), providing improved performance characteristics. However, the substitute's operating temperature range (-40°C ~ 85°C) is narrower than the original (-55°C ~ 125°C), and its lifetime rating at elevated temperature (2,000 Hrs @ 85°C) is lower than the original (20,000 Hrs @ 125°C). These differences must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 225TTA050M directly replace the MAL212367228 in all applications?

A: Direct substitution is electrically valid for the core capacitance and voltage specifications. However, three factors require evaluation: (1) Physical dimensions differ, requiring PCB layout verification; (2) Operating temperature range is narrower on the substitute; (3) Lifetime rating at elevated temperature is significantly lower. Applications operating continuously at temperatures above 85°C or requiring the full -55°C lower temperature limit must be reassessed.

Q: Why is the substitute part's voltage rating higher (50 V vs. 40 V)?

A: Higher voltage-rated capacitors are acceptable substitutes for lower voltage applications. The 50 V rating provides additional safety margin and does not negatively impact circuit performance when used in 40 V circuits.

Q: What is the impact of the smaller physical size of the substitute part?

A: The 225TTA050M measures 5.00mm diameter x 13.00mm length, compared to 6.70mm x 15.30mm for the original. This smaller footprint may allow direct mounting in existing through-hole positions, but PCB layout and component spacing must be verified to ensure no mechanical interference with adjacent components.

Q: Does the lower ESR of the substitute part affect circuit performance?

A: Lower ESR (90.43 Ohm vs. 109 Ohm) is generally beneficial, reducing heat generation and improving ripple current handling. This represents an improvement over the original specification.

Q: Is the RoHS3 compliance of the substitute part significant?

A: Yes. The substitute's ROHS3 compliance makes it suitable for applications and markets requiring RoHS certification, whereas the original non-compliant part may face restrictions in certain jurisdictions or customer specifications.

Q: How do the ripple current ratings compare?

A: The substitute provides higher ripple current capability (23 mA @ 120 Hz vs. 11 mA @ 100 Hz), indicating improved performance in applications with AC ripple current stress.
