Nichicon UPW1V151MPH Equivalent & Substitute Parts

Part Overview

The Nichicon UPW1V151MPH is a 150 µF, 35 V aluminum electrolytic capacitor in radial, can package rated for 3000 hours at 105°C. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing maintenance, repair, and legacy system support. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts offer compatible performance within the allowed parameter tolerances for this capacitor category.

Substitute Part Grouping Explanation

Substitution for the UPW1V151MPH is determined by strict equivalence in the following critical parameters:

Capacitance Value: 150 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Package Configuration: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.138" (4.60 mm) (exact match required)
Case Diameter: 0.315" (8.00 mm) (exact match required)
Operating Temperature Range: -55°C to 105°C (exact match required)
Polarization: Polar (exact match required)

Parts meeting all these criteria are classified as direct equivalents. Variations in lifetime rating, ripple current specifications, or compliance certifications do not disqualify a part from substitution, provided all mechanical and primary electrical parameters remain identical.

Engineering Selection Recommendations

UPW1V151MPD (Nichicon): This part is a direct equivalent to the UPW1V151MPH, matching all critical electrical and mechanical parameters. It carries ROHS3 compliance and maintains the same 3000-hour lifetime rating at 105°C. Although classified as "Not For New Designs," it remains suitable for replacement in existing systems where the UPW1V151MPH is no longer available.

EEU-FC1V151 (Panasonic Electronic Components): This part meets all mechanical and primary electrical specifications required for substitution. It is classified as Active and carries both ROHS3 compliance and AEC-Q200 automotive qualification. The height specification differs by 0.039" (1.00 mm), and the lifetime rating is 2000 hours at 105°C compared to 3000 hours for the main part. These differences do not prevent substitution in applications where the mechanical envelope and thermal lifetime are acceptable.
