Nichicon UTT1C151MPD Equivalent & Substitute Parts

Part Overview

The Nichicon UTT1C151MPD is a 150 µF, 16 V aluminum electrolytic capacitor in radial through-hole configuration, rated for 5000 hours at 105°C. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The UTT series represents an older generation of general-purpose aluminum electrolytic capacitors. Substitute parts maintain the core capacitance and tolerance specifications while offering improved performance characteristics, extended operational lifetimes, or alternative mounting technologies.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UTT1C151MPD is determined by the following critical parameters:

• Capacitance Value: 150 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: Minimum 16 V (equal or higher voltage ratings are acceptable)
• Mounting Type: Through-hole radial configuration (primary substitutes maintain this form factor)
• Lead Spacing: 0.138" (4.60mm) for through-hole variants
• RoHS Compliance: ROHS3 Compliant (maintained across all substitutes)

Substitute parts are grouped into two categories:

1. Direct Through-Hole Radial Substitutes: Parts maintaining identical mounting technology and lead spacing, with equal or higher voltage ratings and improved or equivalent lifetime specifications.

2. Surface Mount Alternative: Parts with identical electrical specifications but surface-mount technology, suitable for applications where PCB redesign is feasible.

Parameter Comparison

Engineering Selection Recommendations

UPW1E151MPD (Manufacturer Recommended): This part maintains through-hole radial configuration with identical lead spacing and capacitance specifications. The 25 V voltage rating provides margin above the 16 V requirement. However, the 3000-hour lifetime at 105°C is reduced compared to the main part. This substitute is classified as "Not For New Designs," indicating limited future availability. Selection is appropriate for legacy system maintenance where voltage margin is beneficial.

UCW1C151MCL1GS (Active Status): This surface-mount variant offers the longest operational lifetime at 7000 hours at 105°C and maintains active product status, ensuring continued availability. The 16 V voltage rating matches the original specification exactly. Selection requires PCB redesign to accommodate surface-mount technology and the smaller 0.248" diameter package. This option is optimal for new designs or redesigned applications prioritizing component longevity and supply chain stability.

UHV1V151MPD (Higher Voltage Rating): This part provides a 35 V voltage rating with 6000-hour lifetime at 105°C, maintaining through-hole radial configuration. The higher voltage rating offers additional design margin for applications subject to voltage transients. Product status is "Not For New Designs," similar to UPW1E151MPD. Selection is appropriate when elevated voltage stress mitigation is required in legacy systems.

All substitute parts maintain ROHS3 compliance and are manufactured by Nichicon, ensuring regulatory consistency and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can UPW1E151MPD directly replace UTT1C151MPD in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical capacitance (150 µF), tolerance (±20%), lead spacing (0.138" / 4.60mm), and through-hole radial mounting. The 25 V rating of UPW1E151MPD exceeds the 16 V requirement, providing voltage margin. However, the reduced 3000-hour lifetime versus the original 5000-hour specification should be evaluated against application duty cycles.

Q: What is the primary advantage of UCW1C151MCL1GS?

A: UCW1C151MCL1GS is the only active product among the substitutes, ensuring long-term supply availability. It delivers the highest operational lifetime at 7000 hours at 105°C. The trade-off is surface-mount technology, which requires PCB redesign and different assembly processes compared to through-hole mounting.

Q: When should UHV1V151MPD be selected over other substitutes?

A: UHV1V151MPD is appropriate when circuit design includes voltage transients or when additional voltage stress margin is required. The 35 V rating provides the highest voltage headroom. The 6000-hour lifetime at 105°C is intermediate between other options. Through-hole radial mounting maintains compatibility with existing PCB layouts.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the regulatory status of the original UTT1C151MPD.

Q: What is the impact of different impedance values among substitutes?

A: Impedance differences reflect internal construction variations. UPW1E151MPD (117 mOhms) and UHV1V151MPD (59 mOhms) offer lower impedance than the original (680 mOhms), improving high-frequency ripple current handling. UCW1C151MCL1GS (1 Ohms) shows higher impedance due to surface-mount construction. For general-purpose applications, these variations are within acceptable operating margins.

Q: Can surface-mount UCW1C151MCL1GS be used in through-hole applications?

A: No. UCW1C151MCL1GS requires surface-mount assembly on compatible PCB land patterns. Through-hole applications require UPW1E151MPD or UHV1V151MPD.
