UHM0J182MPD Equivalent & Substitute Parts

Part Overview

The UHM0J182MPD is a 1800 µF, 6.3 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part is rated for 2000 hours at 105°C and is suitable for general-purpose applications requiring polar electrolytic capacitors with through-hole mounting.

Substitute Part Grouping Explanation

Substitution for the UHM0J182MPD is determined by strict equivalence in the following parameters:

Capacitance: 1800 µF (exact match required)
Voltage Rating: 6.3 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in lifetime rating, impedance, ripple current specifications, and physical dimensions (diameter and height) are secondary considerations and do not disqualify a part from substitution eligibility, provided the primary parameters remain equivalent.

Engineering Selection Recommendations

For applications requiring the UHM0J182MPD, the following selection criteria apply based on product status and compliance:

Active Status Parts (Preferred for New Designs):

EEU-FR0J182 and EEU-FR0J182B (Panasonic) are both active products with ROHS3 compliance and extended 8000-hour lifetime ratings. These parts offer the lowest impedance (28 mOhms) among available substitutes and are suitable for new design implementations.
EKY-6R3ELL182MK15S (Chemi-Con) is an active product with ROHS3 compliance and 8000-hour lifetime rating. This part has a larger diameter (0.492") and different height (0.650") compared to the original, requiring PCB layout verification.

Not For New Designs Parts (Maintenance and Legacy Support):

UHE0J182MHD and UHV0J182MPD (Nichicon) are classified as not for new designs but remain available for legacy system maintenance. UHV0J182MPD maintains the original diameter (0.394") with extended height (0.689"), while UHE0J182MHD has increased diameter (0.492") with reduced height (0.591").

All substitute parts maintain the core electrical specifications: 1800 µF capacitance, 6.3 V voltage rating, ±20% tolerance, polar configuration, through-hole mounting, and 5.00 mm lead spacing.

Frequently Asked Questions (FAQ)

Q: Can I use EEU-FR0J182 as a direct replacement for UHM0J182MPD? A: Yes. Both parts meet the core substitution criteria: 1800 µF, 6.3 V, ±20% tolerance, polar, through-hole mounting, and 5.00 mm lead spacing. The EEU-FR0J182 has identical diameter (0.394") but greater height (0.689" vs. 0.630"), requiring verification of available PCB clearance.

Q: What is the difference between EEU-FR0J182 and EEU-FR0J182B? A: Both parts are electrically and mechanically identical. The primary difference is packaging: EEU-FR0J182 is supplied in bulk, while EEU-FR0J182B is supplied in cut tape format. Selection depends on procurement and assembly requirements.

Q: Why does EKY-6R3ELL182MK15S have a larger diameter than the original part? A: The EKY-6R3ELL182MK15S maintains all core electrical parameters but uses a different physical form factor (0.492" diameter vs. 0.394"). This is a valid substitute provided PCB layout accommodates the increased diameter and the height specification (0.650") fits available clearance.

Q: Are all substitute parts RoHS compliant? A: EEU-FR0J182, EEU-FR0J182B, UHE0J182MHD, UHV0J182MPD, and EKY-6R3ELL182MK15S are all ROHS3 compliant. The original UHM0J182MPD does not carry RoHS certification.

Q: Which substitute part has the lowest impedance? A: EEU-FR0J182 and EEU-FR0J182B both have 28 mOhms impedance, the lowest among available substitutes. The original UHM0J182MPD has 19 mOhms impedance.

Q: Can I use parts rated for longer lifetimes (8000 hours) in place of the 2000-hour original? A: Yes. Extended lifetime ratings (8000 hours at 105°C) are compatible with applications originally designed for 2000-hour rated parts. This represents an improvement in component reliability and does not create compatibility issues.
