MAL212366221 Equivalent & Substitute Parts

Part Overview

The MAL212366221 is a 220 µF, 25 V aluminum electrolytic capacitor in axial configuration, manufactured by Vishay Beyschlag/Draloric/BC Components. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement. The part operates across a temperature range of -55°C to 125°C with a rated lifetime of 20,000 hours at 125°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAL212366221 is determined by the following critical parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 25 V (minimum requirement; higher ratings acceptable)
• Tolerance: ±20% (standard tolerance for aluminum electrolytic capacitors)
• Package configuration: Axial, Can through-hole mounting
• Polarization: Polar configuration for standard electrolytic operation

The substitute part 227BPA025M meets the core electrical specifications (220 µF, 25 V, ±20% tolerance) and maintains axial through-hole packaging. However, differences exist in ESR characteristics, lifetime ratings, operating temperature range, and physical dimensions. These variations must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 227BPA025M serves as an active substitute for the obsolete MAL212366221 based on matching core electrical specifications: 220 µF capacitance, 25 V voltage rating, and ±20% tolerance. Both components feature axial through-hole packaging suitable for PCB integration.

Key considerations for selection:

The 227BPA025M is ROHS3 compliant, whereas the MAL212366221 is non-compliant. For applications subject to RoHS regulations, the 227BPA025M is the appropriate choice.

The MAL212366221 provides extended operating temperature range (-55°C to 125°C) and significantly higher lifetime rating (20,000 hours at 125°C) compared to the 227BPA025M (2,000 hours at 85°C). Applications requiring operation at elevated temperatures or extended service life should evaluate whether the substitute meets thermal and reliability requirements.

The 227BPA025M has reduced physical dimensions (10.00mm x 24.00mm versus 12.90mm x 32.00mm), which may affect PCB layout compatibility. Physical space constraints must be verified before substitution.

Ripple current handling differs between parts: MAL212366221 supports 460 mA at 100Hz, while 227BPA025M supports 390 mA at 120Hz. Applications with high ripple current demands should confirm the substitute's capacity.

Frequently Asked Questions (FAQ)

Q: Can the 227BPA025M directly replace the MAL212366221 in all applications?

A: The 227BPA025M matches the core electrical specifications (220 µF, 25 V, ±20% tolerance) and packaging type (axial through-hole). However, differences in operating temperature range, lifetime rating, ripple current capacity, and physical dimensions require application-specific evaluation. Thermal environment and reliability requirements must be assessed.

Q: What are the physical space implications of substitution?

A: The 227BPA025M is physically smaller (10.00mm x 24.00mm) compared to the MAL212366221 (12.90mm x 32.00mm). PCB layouts designed for the larger original component will accommodate the substitute without space conflicts. However, designs with tight spatial constraints around the original component location should verify clearance.

Q: How do the lifetime ratings compare?

A: The MAL212366221 is rated for 20,000 hours at 125°C, while the 227BPA025M is rated for 2,000 hours at 85°C. These represent different thermal stress conditions. Applications operating continuously at elevated temperatures should evaluate whether the substitute's lifetime rating is acceptable for the intended service duration.

Q: Are there compliance differences between these parts?

A: Yes. The MAL212366221 is RoHS non-compliant, while the 227BPA025M is ROHS3 compliant. For systems subject to RoHS directives, the 227BPA025M is the required choice.

Q: What is the ESR difference, and does it matter?

A: ESR values are comparable: 1.5 Ohm @ 100Hz (MAL212366221) versus 1.507 Ohm @ 120Hz (227BPA025M). The negligible difference has minimal impact on circuit performance in general-purpose applications. Applications with specific ESR requirements should confirm the substitute meets those criteria.

Q: Can the 227BPA025M handle the same ripple current as the original?

A: The MAL212366221 supports 460 mA at 100Hz, while the 227BPA025M supports 390 mA at 120Hz. The substitute has lower ripple current capacity. Applications with ripple current demands exceeding 390 mA should confirm the substitute is suitable or consider alternative parts.
