Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAL212366221E3 is determined by the following critical parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Axial, Can through-hole (exact match required)
• Polarization: Polar (required for general-purpose applications)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The substitute part 227BPA025M meets the core electrical specifications (220 µF, 25 V, ±20% tolerance) and maintains the same axial through-hole package configuration. Both parts are ROHS3 compliant and suitable for direct replacement in circuit designs where the specified parameters are required.

Parameter Comparison

Engineering Selection Recommendations

The 227BPA025M serves as an active substitute for the obsolete MAL212366221E3. Both components satisfy the core electrical requirements of 220 µF capacitance at 25 V with ±20% tolerance in axial through-hole configuration. Both parts maintain ROHS3 compliance and REACH unaffected status.

The substitute part features comparable ESR characteristics (1.507 Ohm vs. 1.5 Ohm) and adequate ripple current handling at low frequencies (390 mA @ 120 Hz vs. 460 mA @ 100 Hz). The primary design consideration is the reduced operating temperature range (-40°C to 85°C versus -55°C to 125°C) and lower lifetime rating (2000 Hrs @ 85°C versus 20000 Hrs @ 125°C). Applications requiring operation at temperatures below -40°C or above 85°C, or demanding extended service life at elevated temperatures, require alternative evaluation.

The substitute part is physically smaller (10.00mm diameter vs. 12.90mm diameter), which may provide layout advantages in space-constrained designs while maintaining mechanical compatibility through standard axial lead spacing.

Frequently Asked Questions (FAQ)

Q: Can the 227BPA025M directly replace the MAL212366221E3 in all applications?

A: Direct replacement is suitable for applications operating within -40°C to 85°C. Applications requiring the full -55°C to 125°C temperature range of the original part require alternative components.

Q: What are the physical differences between these parts?

A: The substitute part (227BPA025M) is smaller: 10.00mm diameter x 24.00mm length versus 12.90mm diameter x 32.00mm length for the original. Both maintain standard axial lead spacing for through-hole mounting.

Q: Are both parts RoHS compliant?

A: Yes, both MAL212366221E3 and 227BPA025M are ROHS3 compliant and REACH unaffected.

Q: How do the ESR values compare?

A: ESR values are nearly identical: 1.5 Ohm @ 100Hz (original) versus 1.507 Ohm @ 120Hz (substitute), indicating equivalent performance in filtering and ripple current applications.

Q: What is the significance of the different lifetime ratings?

A: The original part specifies 20000 hours at 125°C, while the substitute specifies 2000 hours at 85°C. For applications requiring extended service life at high temperatures, the original specification should be referenced or alternative parts evaluated.

Q: Is the lower ripple current rating of the substitute part a concern?

A: The substitute part handles 390 mA @ 120 Hz versus 460 mA @ 100 Hz for the original. For applications with ripple current demands below 390 mA, the substitute is suitable. Higher ripple current applications require alternative evaluation.
