UPT2D151MHD Equivalent & Substitute Parts

Part Overview

The UPT2D151MHD is a 150 µF, 200 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 part is active and ROHS3 compliant. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance) and mechanical compatibility (lead spacing, case dimensions, mounting type) while accounting for variations in lifetime ratings and ripple current capabilities.

Substitute Part Grouping Explanation

Substitution for the UPT2D151MHD is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

Capacitance: 150 µF (exact match required)
Voltage Rating: 200 V (exact match required)
Tolerance: ±20% (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Polarization: Polar (exact match required)

Allowable Variations:

Lead Spacing: Substitutes with 0.295" (7.50 mm) spacing are acceptable for applications where PCB layout permits increased pitch
Case Diameter: Substitutes with larger diameters (0.630" or 0.709") are acceptable where board space allows
Height: Substitutes with different heights are acceptable based on available clearance
Lifetime @ 105°C: Substitutes with equal or greater lifetime ratings are acceptable
Ripple Current: Substitutes with equal or greater ripple current ratings are acceptable
Operating Temperature Range: Substitutes with equal or wider temperature ranges are acceptable

Panasonic EEU series parts (EB-A, ED-A, EE-A) and Nichicon UCY series parts meet these criteria with variations in physical dimensions and performance characteristics.

Engineering Selection Recommendations

Direct Replacement (Identical Footprint): UCY2D151MHD is the direct Nichicon equivalent with identical lead spacing (5.00 mm) and case diameter (12.50 mm). This part offers extended lifetime (12000 hours vs. 5000 hours), wider operating temperature range (-40°C to 105°C), and higher ripple current ratings. All parts are ROHS3 compliant and active products.

Space-Constrained Substitutes (Larger Footprint): Panasonic EEU series parts (EB-A, ED-A, EE-A) require increased lead spacing (7.50 mm) and larger case diameters (16.00 mm or 18.00 mm). These substitutes are suitable only when PCB layout accommodates the larger pitch and diameter. EEU-ED2D151 and EEU-EE2D151 offer extended lifetime ratings (10000 hours), while EEU-EB2D151 and EEU-EB2D151S match the 5000-hour lifetime of the original part.

Compliance Considerations: All substitute parts maintain ROHS3 compliance. EEU-ED2D151 and EEU-ED2D151B carry MSL rating of 1 (Unlimited), while other parts are not applicable for MSL. REACH status varies: UCY2D151MHD is REACH Affected; all Panasonic parts and UPT2D151MHD are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can UCY2D151MHD be used as a direct replacement for UPT2D151MHD? A: Yes. UCY2D151MHD is a direct replacement with identical electrical specifications (150 µF, 200 V, ±20%) and identical mechanical dimensions (5.00 mm lead spacing, 12.50 mm diameter, 37.00 mm height). The
