Substitute Part Grouping Explanation

The 226TTA050M from Cornell Dubilier / Illinois Capacitor qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Capacitance: 22 µF (identical)
• Tolerance: ±20% (identical)
• Polarization: Polar (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Axial, Can (identical)

Allowable Deviations:

• Voltage - Rated: 50 V (substitute exceeds 40 V requirement, providing margin)
• ESR: 9.0429 Ohm @ 120 Hz (substitute exhibits lower ESR, improving performance)
• Ripple Current @ Low Frequency: 85 mA @ 120 Hz (substitute meets or exceeds 89 mA @ 100 Hz specification)

The substitute part maintains electrical compatibility through higher voltage rating and superior ESR characteristics while preserving identical capacitance, tolerance, and mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

The 226TTA050M is an active product with ROHS3 compliance, addressing the obsolescence status of the MAL212367229. The substitute maintains identical capacitance and tolerance specifications while providing a higher voltage rating (50 V vs. 40 V), which ensures adequate safety margin in circuit applications. The lower ESR of the substitute (9.0429 Ohm @ 120 Hz vs. 11 Ohm @ 100 Hz) represents an improvement in performance characteristics.

Design consideration: The substitute operates within a reduced temperature range (-40°C to 85°C versus -55°C to 125°C) and has a shorter lifetime rating at temperature (2,000 Hrs @ 85°C versus 20,000 Hrs @ 125°C). Applications requiring operation at temperatures below -40°C or sustained operation above 85°C require evaluation against the original part's extended specifications. The substitute's smaller physical dimensions (6.30 mm x 13.00 mm versus 9.40 mm x 23.30 mm) may provide layout advantages in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the 226TTA050M directly replace the MAL212367229 in all applications?

A: The 226TTA050M is electrically compatible for applications operating within -40°C to 85°C. Applications requiring the original part's extended temperature range (-55°C to 125°C) or extended lifetime rating (20,000 Hrs @ 125°C) require circuit-level evaluation.

Q: What is the significance of the voltage rating difference (40 V vs. 50 V)?

A: The substitute's higher voltage rating (50 V) provides additional safety margin and is compatible with circuits designed for 40 V operation. No derating is required when substituting a higher-voltage-rated capacitor in a lower-voltage application.

Q: How do the ESR values affect circuit performance?

A: The substitute exhibits lower ESR (9.0429 Ohm @ 120 Hz versus 11 Ohm @ 100 Hz), which reduces heat dissipation and improves ripple current handling. This represents an improvement over the original part's characteristics.

Q: Are there physical installation considerations due to size differences?

A: The substitute is physically smaller (0.248" Dia x 0.512" L versus 0.370" Dia x 0.917" L). Verify that the reduced dimensions are compatible with existing PCB layouts and mechanical mounting provisions. Both parts maintain identical axial lead configuration and through-hole mounting type.

Q: What compliance differences exist between the two parts?

A: The MAL212367229 is RoHS non-compliant, while the 226TTA050M is ROHS3 compliant. For applications subject to RoHS regulations, the substitute satisfies compliance requirements.
