Substitute Part Grouping Explanation

Substitution eligibility for the LDQ2G820MERYGA is determined by the following mandatory parameters:

Capacitance: 82 µF (exact match required)
Voltage Rating: 400 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -25°C to 105°C (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)

All identified substitute parts meet these core electrical and mechanical criteria. Variations in lifetime rating, ripple current specifications, physical dimensions (diameter and height), and manufacturer do not disqualify substitution but indicate performance differences in specific application contexts.

Engineering Selection Recommendations

Active Product Selection: UPT2G820MHD is the recommended substitute when component availability or supply chain requirements necessitate an alternative to LDQ2G820MERYGA. Both parts are manufactured by Nichicon and maintain active product status. UPT2G820MHD provides extended operational lifetime (5000 hours at 105°C versus 2000 hours), offering improved reliability margin in applications subject to thermal stress.

Extended Lifetime Applications: EEU-ED2G820 and EEU-EE2G820 (Panasonic) are suitable substitutes for applications requiring maximum operational longevity. Both parts are rated for 10000 hours at 105°C. These components carry obsolete product status; selection should account for long-term supply availability and inventory planning.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the primary component. No additional regulatory assessment is required for substitution within equivalent application contexts.

Frequently Asked Questions (FAQ)

Q: Can UPT2G820MHD be used as a direct replacement for LDQ2G820MERYGA?

A: Yes. Both components share identical electrical specifications (82 µF, 400 V, ±20% tolerance), operating temperature range (-25°C to 105°C), lead spacing (7.50 mm), and through-hole radial can package configuration. Physical dimensions differ slightly; verify PCB layout clearance before substitution.

Q: What is the significance of the lifetime rating difference?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation exceeds tolerance limits. LDQ2G820MERYGA (2000 hours) is suitable for standard applications. UPT2G820MHD (5000 hours) and Panasonic alternatives (10000 hours) provide extended service life for thermally demanding environments or applications requiring higher reliability margins.

Q: Are Panasonic EEU-ED2G820 and EEU-EE2G820 still available for new designs?

A: Both Panasonic parts carry obsolete product status. While inventory may be available through distribution channels, these components are not recommended for new product designs. Active alternatives (LDQ2G820MERYGA or UPT2G820MHD) should be prioritized for long-term supply security.

Q: Do all substitute parts fit the same PCB footprint?

A: All parts share identical lead spacing (7.50 mm) and through-hole mounting type. Physical can diameter and height vary: LDQ2G820MERYGA (20.00 mm diameter × 30.00 mm height), UPT2G820MHD (16.00 mm diameter × 33.00 mm height), EEU-ED2G820 (18.00 mm diameter × 40.00 mm height), and EEU-EE2G820 (18.00 mm diameter × 34.60 mm height). Verify mechanical clearance in the application before substitution.

Q: Are there differences in ripple current handling between these parts?

A: Ripple current specifications vary across the substitute group. These differences reflect internal design variations and do not affect substitution eligibility when core electrical parameters match. Application-specific ripple current requirements should be evaluated against the datasheet specifications of the selected component.
