Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UBT2W330MHD8 must maintain electrical equivalence across the following critical parameters: capacitance value of 33 µF, voltage rating of 450 V, tolerance of ±20%, and operating temperature range of -25°C to 125°C. Mechanical compatibility requires identical mounting type (through hole), package configuration (radial, can), lead spacing of 0.295" (7.50mm), and physical dimensions (0.630" diameter, 1.319" maximum seated height). Thermal performance must match or exceed the 2000-hour lifetime specification at 125°C. Compliance requirements include ROHS3 status and REACH affected designation. Ripple current ratings at both 120 Hz and 100 kHz must be maintained at or above the specified values of 203 mA and 365.4 mA respectively.

Parameter Comparison

Engineering Selection Recommendations

The UBT2W330MHD8 is an active production component with full ROHS3 compliance and REACH affected status. Selection of substitute parts must prioritize maintenance of all specified electrical parameters, thermal performance characteristics, and mechanical dimensions to ensure direct board-level compatibility. The automotive application classification requires strict adherence to rated voltage, capacitance tolerance, and ripple current specifications. Active product status ensures continued availability and supply chain stability. Compliance certifications must remain consistent across all selected alternatives.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must remain constant when selecting a substitute for the UBT2W330MHD8?

A: The capacitance value (33 µF), voltage rating (450 V), tolerance (±20%), and operating temperature range (-25°C to 125°C) must remain unchanged. Ripple current ratings at both 120 Hz (203 mA minimum) and 100 kHz (365.4 mA minimum) must be maintained or exceeded.

Q: Are mechanical dimensions critical for substitution?

A: Yes. The through-hole mounting type, radial can package configuration, lead spacing of 0.295" (7.50mm), diameter of 0.630" (16.00mm), and maximum seated height of 1.319" (34.60mm) must be identical to ensure PCB compatibility without redesign.

Q: What compliance requirements apply to substitute parts?

A: Substitute parts must maintain ROHS3 compliance status and REACH affected designation. The 2000-hour lifetime specification at 125°C must be met or exceeded for automotive applications.

Q: Can parts with different manufacturers be used as substitutes?

A: Substitute parts must match all electrical, thermal, mechanical, and compliance parameters specified for the UBT2W330MHD8. Manufacturer equivalence is determined by parameter matching, not brand preference.

Q: How does polarization affect substitution?

A: The UBT2W330MHD8 is a polar capacitor. Substitute parts must maintain polar configuration. Polarity orientation on the PCB must be observed during installation.
