Engineering Selection Recommendations

ELXZ6R3ELL222MJ25S (Chemi-Con LXZ Series)

This substitute part maintains identical electrical specifications to the 228KXM6R3M with 2200 µF capacitance at 6.3 V rated voltage. The ELXZ6R3ELL222MJ25S offers an extended lifetime of 5000 hours at 105°C compared to the 4000-hour rating of the main part, representing improved thermal endurance. Physical dimensions are compatible with the original design, with a maximum seated height of 26.50 mm (0.5 mm shorter than the main part). The part is ROHS3 compliant and carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications. This substitute is appropriate for applications where extended operational life at elevated temperature is beneficial.

UPA1A222MPD (Nichicon UPA Series)

This substitute part provides 2200 µF capacitance with a rated voltage of 10 V, which exceeds the 6.3 V requirement of the main part. The higher voltage rating provides additional design margin and is electrically compatible with circuits designed for 6.3 V operation. The UPA1A222MPD maintains identical operating temperature range and lifetime specifications of 4000 hours at 105°C. Physical dimensions match the original part exactly, including 27.00 mm maximum seated height. The part is ROHS3 compliant. The REACH status indicates REACH Affected, requiring verification of regulatory compliance in specific end-use applications. This substitute is appropriate for applications where voltage margin enhancement is desired or where higher voltage rating components are preferred for design robustness.

Frequently Asked Questions (FAQ)

Q: Can ELXZ6R3ELL222MJ25S be used as a direct replacement for 228KXM6R3M?

A: Yes. Both parts share identical capacitance (2200 µF), voltage rating (6.3 V), tolerance (±20%), operating temperature range (-55°C to 105°C), and physical dimensions (10.00 mm diameter, 5.00 mm lead spacing). The ELXZ6R3ELL222MJ25S is mechanically and electrically compatible for direct PCB substitution.

Q: Can UPA1A222MPD be used as a direct replacement for 228KXM6R3M?

A: Yes. The UPA1A222MPD shares identical capacitance (2200 µF), tolerance (±20%), operating temperature range (-55°C to 105°C), and physical dimensions (10.00 mm diameter, 5.00 mm lead spacing). The 10 V rated voltage exceeds the 6.3 V requirement and is compatible with circuits designed for the lower voltage specification. The part is mechanically and electrically compatible for direct PCB substitution.

Q: What is the significance of the height difference between 228KXM6R3M (27.00 mm) and ELXZ6R3ELL222MJ25S (26.50 mm)?

A: The 0.5 mm height difference is within typical PCB assembly tolerances and does not affect mechanical compatibility. The ELXZ6R3ELL222MJ25S is slightly shorter, which may provide additional clearance in space-constrained applications. Both parts fit within the same footprint envelope.

Q: Why does UPA1A222MPD have a higher voltage rating (10 V) than the main part (6.3 V)?

A: Higher voltage-rated capacitors are electrically compatible with lower voltage applications. The 10 V rating provides additional voltage margin and is suitable for circuits designed for 6.3 V operation. This substitution is valid and does not compromise circuit function.

Q: Are all three parts RoHS compliant?

A: Yes. The 228KXM6R3M, ELXZ6R3ELL222MJ25S, and UPA1A222MPD are all ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the difference in impedance between these parts?

A: The main part 228KXM6R3M has 66 mOhms impedance, while ELXZ6R3ELL222MJ25S has 45 mOhms and UPA1A222MPD has 33 mOhms. Lower impedance values indicate reduced equivalent series resistance and improved high-frequency performance characteristics. All values are within acceptable ranges for general purpose and automotive applications.

Q: Does the AEC-Q200 rating on ELXZ6R3ELL222MJ25S affect its use in non-automotive applications?

A: No. AEC-Q200 is an automotive qualification standard. Parts meeting this standard exceed general purpose requirements and are suitable for use in any application, including non-automotive circuits. The qualification indicates enhanced reliability and quality assurance.

Q: What does REACH Affected status mean for UPA1A222MPD?

A: REACH Affected indicates the part is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. Verification of compliance with specific end-use application regulations is required before deployment in regulated markets or applications.
