Engineering Selection Recommendations

Both MAL216051221E3 and MAL216061221E3 are direct functional equivalents to the UBX1H221MPL. Selection between the two substitute parts should be based on procurement availability and lead time, as they are electrically and mechanically identical.

The substitute parts offer the advantage of active product status, ensuring long-term availability and supply chain continuity. Both parts carry AEC-Q200 automotive qualification, meeting the same application requirements as the original component. The marginal height difference of 0.020" (0.50 mm) between the original and substitute parts is within typical PCB layout tolerances for through-hole radial capacitors.

Frequently Asked Questions (FAQ)

Q: Can MAL216051221E3 or MAL216061221E3 be used as direct replacements for UBX1H221MPL?

A: Yes. Both substitute parts match all critical electrical parameters (220 µF, 50 V, ±20% tolerance), operating temperature range (-55°C to 150°C), and mechanical specifications (radial can package, 5.00 mm lead spacing, 10.00 mm diameter). Both are ROHS3 compliant and carry AEC-Q200 automotive qualification.

Q: What is the difference between MAL216051221E3 and MAL216061221E3?

A: Both parts are electrically and mechanically identical. They are both from Vishay's 160 RLA series with identical electrical specifications and physical dimensions. Selection between them should be based on inventory availability and procurement lead times.

Q: Will the substitute parts fit the existing PCB layout?

A: The substitute parts have identical lead spacing (5.00 mm) and case diameter (10.00 mm) as the original component. The seated height is 0.866" (22.00 mm) compared to the original 0.846" (21.50 mm), a difference of 0.020" (0.50 mm). This minimal difference is within standard PCB design tolerances for radial capacitor mounting.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both MAL216051221E3 and MAL216061221E3 carry AEC-Q200 qualification and are rated for automotive applications with the same operating temperature range and lifetime specifications as the original UBX1H221MPL.

Q: What is the impedance of the substitute parts?

A: Both substitute parts have an impedance of 170 mOhms, providing consistent electrical performance in the circuit.
