Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance value (33 µF), tolerance (±20%), polarization (Polar), mechanical dimensions (0.394" diameter, 1.319" height, 5.00 mm lead spacing), mounting type (Through Hole), and package configuration (Radial, Can). Voltage rating may be equal to or greater than the original specification. Lifetime at rated temperature and ripple current ratings are secondary parameters that may vary between substitutes. All substitute parts maintain ROHS3 compliance and identical operating temperature range (-25°C ~ 105°C).

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original UPH2G330MPD specification. Selection between substitutes depends on application-specific requirements:

UCP2G330MPD provides extended operational lifetime (10000 Hrs @ 105°C versus 2000 Hrs) while maintaining the original 400 V voltage rating and identical mechanical footprint. This substitute is suitable for applications requiring enhanced reliability over extended service intervals.

UCPW6330MPD and UPHW6330MPD both feature elevated voltage rating (420 V) compared to the original 400 V specification, providing additional voltage margin. UCPW6330MPD combines the 420 V rating with extended lifetime (10000 Hrs @ 105°C), while UPHW6330MPD maintains the 2000 Hrs lifetime characteristic of the original series.

All substitutes are mechanically and electrically compatible with the original part within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can UCP2G330MPD directly replace UPH2G330MPD in existing designs?

A: Yes. UCP2G330MPD maintains identical capacitance (33 µF), voltage rating (400 V), tolerance (±20%), mechanical dimensions, lead spacing, and mounting configuration. The extended lifetime rating (10000 Hrs @ 105°C) represents an enhancement without introducing incompatibility.

Q: What is the difference between 400 V and 420 V rated substitutes?

A: The 420 V rating provides 5% additional voltage margin above the original 400 V specification. Both UCPW6330MPD and UPHW6330MPD are electrically and mechanically compatible with circuits designed for 400 V operation. The elevated rating does not affect capacitance, tolerance, or physical dimensions.

Q: Are all substitute parts suitable for the same PCB layout?

A: Yes. All substitute parts share identical lead spacing (5.00 mm), case diameter (10.00 mm), and maximum seated height (34.60 mm). No PCB redesign or footprint modification is required.

Q: What is the significance of lifetime rating differences?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. UCP series parts (10000 Hrs) provide extended service life compared to UPH series parts (2000 Hrs). Selection depends on application duty cycle and maintenance intervals.

Q: Do all substitutes maintain RoHS3 compliance?

A: Yes. UCP2G330MPD, UCPW6330MPD, and UPHW6330MPD are all ROHS3 compliant, matching the original UPH2G330MPD specification.
