Substitute Part Grouping Explanation

Substitution of the UPB2E330MHD1TO is determined by strict equivalence across the following electrical and mechanical parameters:

Capacitance value: 33 µF (exact match required)
Voltage rating: 250 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime specification: 5000 Hrs @ 105°C (exact match required)
Operating temperature range: -25°C ~ 105°C (exact match required)
Package configuration: Radial, Can through-hole (exact match required)
Lead spacing: 0.197" (5.00 mm) (exact match required)
Can diameter: 0.492" (12.50 mm) (exact match required)

The EEU-EB2E330 manufactured by Panasonic Electronic Components meets all specified electrical and mechanical parameters and qualifies as a direct substitute.

Engineering Selection Recommendations

The EEU-EB2E330 is the qualified substitute for the obsolete UPB2E330MHD1TO. Both components share identical electrical specifications (33 µF, 250 V, ±20%, 5000 Hrs @ 105°C) and mechanical dimensions (lead spacing, can diameter, through-hole mounting). The Panasonic part maintains active product status, ensuring continued availability and supply chain reliability.

The EEU-EB2E330 carries ROHS3 compliance certification, providing additional environmental and regulatory assurance. The maximum seated height difference of 0.020" (0.50 mm) between the two parts is within typical PCB layout tolerances for through-hole components and does not present a functional constraint.

Frequently Asked Questions (FAQ)

Q: Can the EEU-EB2E330 be used as a direct replacement for the UPB2E330MHD1TO?

A: Yes. Both components meet identical electrical specifications (33 µF, 250 V, ±20%, 5000 Hrs @ 105°C) and share the same mechanical footprint (lead spacing 0.197", can diameter 0.492", through-hole mounting). The 0.020" height difference does not affect PCB compatibility.

Q: What is the primary reason for substitution?

A: The UPB2E330MHD1TO is obsolete. The EEU-EB2E330 is an active product from Panasonic with equivalent performance specifications and superior supply availability.

Q: Are there differences in ripple current ratings?

A: Minor variations exist. The EEU-EB2E330 provides 308 mA @ 120 Hz (versus 300 mA) and 560 mA @ 100 kHz (versus 600 mA). These differences do not affect substitution eligibility, as both parts meet the same lifetime and temperature specifications.

Q: Does the Panasonic part require any circuit modifications?

A: No. The EEU-EB2E330 maintains identical voltage rating, capacitance, tolerance, and operating temperature range. No circuit design changes are required.

Q: What compliance certifications apply to the substitute part?

A: The EEU-EB2E330 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
