UPB2G820MHD Equivalent & Substitute Parts

Part Overview

The UPB2G820MHD is an 82 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The UPB2G820MHD is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the UPB2G820MHD is determined by the following critical parameters: capacitance value (82 µF), voltage rating (400 V minimum), tolerance (±20%), lead spacing (0.295" / 7.50 mm), and through-hole mounting compatibility. Physical dimensions and lifetime ratings are secondary considerations that may vary within acceptable design margins.

Substitute parts are grouped into three categories:

Direct Substitutes maintain identical electrical specifications and physical footprints, differing only in series designation or product status.

Upgrade Substitutes provide higher voltage ratings or improved ripple current handling while maintaining the same capacitance, tolerance, and lead spacing.

Similar Substitutes meet core electrical requirements but may have different physical dimensions, lifetime ratings, or ripple current specifications.

Engineering Selection Recommendations

UPT2G820MHD is the primary direct substitute for the UPB2G820MHD. Both parts share identical electrical specifications (82 µF, 400 V, ±20%, 5000 Hrs @ 105°C) and lead spacing. The UPT2G820MHD is active in production and RoHS3 compliant, making it suitable for new designs and production continuity. Physical dimensions are slightly smaller, which may require PCB layout verification.

UPT2W820MHD serves as an upgrade substitute with a higher 450 V voltage rating while maintaining the same capacitance, tolerance, and lifetime. This part is active and RoHS3 compliant. The identical physical footprint to the original UPB2G820MHD allows direct board-level substitution without layout changes.

LDQ2G820MERYGA is an active Nichicon alternative meeting the core electrical requirements. This part has a reduced lifetime rating of 2000 hours at 105°C and different physical dimensions. Selection of this part requires confirmation that the reduced lifetime is acceptable for the application.

EEU-EE2G820 and EEU-ED2G820 are Panasonic alternatives with extended 10000-hour lifetimes at 105°C. Both are obsolete but available in inventory. These parts maintain the 82 µF, 400 V specifications and lead spacing. Physical dimensions differ from the original, requiring PCB layout verification. RoHS3 compliance is confirmed for both.

Frequently Asked Questions (FAQ)

Q: Can UPT2G820MHD be used as a direct replacement for UPB2G820MHD?

A: Yes. Both parts have identical capacitance (82 µF), voltage rating (400 V), tolerance (±20%), lifetime (5000 Hrs @ 105°C), and lead spacing (0.295" / 7.50 mm). The UPT2G820MHD is active in production. Physical dimensions are slightly smaller; verify PCB clearances before implementation.

Q: What is the advantage of using UPT2W820MHD instead of UPT2G820MHD?

A: The UPT2W820MHD provides a higher voltage rating of 450 V compared to 400 V, offering additional design margin in high-voltage applications. All other electrical parameters remain identical. The physical footprint matches the original UPB2G820MHD exactly, allowing direct substitution without PCB modifications.

Q: Are the Panasonic alternatives (EEU-EE2G820, EEU-ED2G820) suitable replacements?

A: Both Panasonic parts meet the core electrical specifications (82 µF, 400 V, ±20%) and lead spacing. Both offer extended 10000-hour lifetimes at 105°C. However, both are obsolete. Physical dimensions differ from the original, requiring PCB layout verification. Use only if inventory availability and lifetime extension justify layout changes.

Q: Why does LDQ2G820MERYGA have a shorter lifetime rating?

A: The LDQ2G820MERYGA is rated for 2000 hours at 105°C, compared to 5000 hours for the UPB2G820MHD. This part is suitable only for applications where the reduced lifetime is acceptable. Verify application requirements before selection.

Q: Do all substitute parts have the same lead spacing?

A: Yes. All substitute parts listed maintain the 0.295" (7.50 mm) lead spacing, ensuring PCB hole compatibility. Physical case diameters and heights vary; verify clearances in your specific layout.

Q: Are all substitute parts RoHS3 compliant?

A: The active parts (UPT2G820MHD, UPT2W820MHD, LDQ2G820MERYGA, EEU-EE2G820, EEU-ED2G820) are RoHS3 compliant. The original UPB2G820MHD is obsolete and does not carry RoHS3 certification.
