Engineering Selection Recommendations

For Direct Footprint Replacement (Same Height):

16ZLH1800MEFC10X23 (Rubycon, Active status, 10000-hour lifetime)
16ZLS1800MEFC10X23 (Rubycon, Active status, 6000-hour lifetime)

Both Rubycon parts maintain the original 0.984" (25.00 mm) height and are currently in active production status, making them suitable for new designs and ongoing production.

For Extended Lifetime with Height Tolerance:

EEU-FR1C182L (Panasonic, Active status, 10000-hour lifetime, Bulk packaging)
EEU-FR1C182LB (Panasonic, Active status, 10000-hour lifetime, Cut Tape packaging)

Panasonic parts offer 10000-hour lifetime ratings and are actively produced. Height increases to 1.063" (27.00 mm); verify PCB layout clearance before selection.

For Nichicon Continuity:

UHV1C182MPD (Nichicon, Not For New Designs, 6000-hour lifetime)

This part extends lifetime to 6000 hours but carries "Not For New Designs" status and increases height to 1.063" (27.00 mm).

Compliance Considerations:

All substitute parts are ROHS3 compliant except the main part UHM1C182MPD
Panasonic and Rubycon parts carry REACH Unaffected or REACH Affected designations; verify regulatory requirements for your application

Frequently Asked Questions (FAQ)

Q: Can I use 16ZLH1800MEFC10X23 as a direct replacement for UHM1C182MPD?

A: Yes. Both parts share identical electrical specifications (1800 µF, 16 V, ±20% tolerance), lead spacing (5.00 mm), case diameter (10.00 mm), and height (25.00 mm). The Rubycon part is currently in active production with extended 10000-hour lifetime.

Q: What is the difference between EEU-FR1C182L and EEU-FR1C182LB?

A: Both Panasonic parts are electrically and mechanically identical. The difference is packaging: EEU-FR1C182L is supplied in Bulk, while EEU-FR1C182LB is supplied in Cut Tape (CT). Select based on your procurement and assembly requirements.

Q: Will the taller Panasonic parts (1.063" height) fit my PCB?

A: The Panasonic parts increase height by 0.079" (2.00 mm) compared to the original UHM1C182MPD. Verify your PCB layout and component clearance specifications before selection. If height is constrained, use 16ZLH1800MEFC10X23 or 16ZLS1800MEFC10X23 (both 0.984" height).

Q: Why is UHV1C182MPD marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While available for legacy system support, Rubycon or Panasonic alternatives are recommended for new designs.

Q: Are all substitute parts RoHS compliant?

A: The original UHM1C182MPD is not RoHS compliant. All substitute parts listed (UHV1C182MPD, 16ZLH1800MEFC10X23, 16ZLS1800MEFC10X23, EEU-FR1C182L, EEU-FR1C182LB) are ROHS3 compliant.

Q: What is the impedance difference between parts, and does it matter?

A: Impedance ranges from 12 mOhms (UHM1C182MPD) to 18 mOhms (Rubycon and Panasonic parts). For general-purpose applications, these variations are within acceptable operating parameters. Verify ripple current and thermal performance requirements for your specific circuit.
