UAS2D151MHD6 Equivalent & Substitute Parts

Part Overview

The UAS2D151MHD6 is a 150 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is Active status and ROHS3 compliant.

Substitute parts are necessary when the original UAS2D151MHD6 becomes unavailable, when higher reliability requirements demand extended lifetime ratings, or when design specifications allow for compatible alternatives with improved electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UAS2D151MHD6 is determined by the following mandatory parameters:

• Capacitance: 150 µF (exact match required)
• Voltage - Rated: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.295" (7.50mm) (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)

Substitute parts may vary in:

• Lifetime @ Temperature: Extended ratings (12000 Hrs, 10000 Hrs, 1000 Hrs) are acceptable
• Size / Dimension: Diameter and height variations within compatible package envelope
• Ripple Current Ratings: Variations in low and high frequency ripple current capacity
• Manufacturer: Alternative manufacturers (Nichicon, Chemi-Con) with equivalent specifications
• Series Designation: Different internal series codes (UAS, UCY, URZ, KXG)

Parameter Comparison

Engineering Selection Recommendations

Direct Mechanical Fit (Identical Footprint)

UCY2D151MHD6 is the optimal substitute when PCB layout constraints require identical lead spacing (0.295" / 7.50mm) and diameter (0.709" / 18.00mm). This part offers 6x extended lifetime (12000 Hrs vs. 2000 Hrs) with improved ripple current handling. Both parts are ROHS3 compliant and Active status.

Extended Lifetime Requirement

UCY2D151MHD3 and EKXG201ELL151ML25S provide 12000 Hrs and 10000 Hrs lifetime ratings respectively, suitable for applications requiring enhanced reliability. Both maintain identical lead spacing (0.295" / 7.50mm) but feature different diameters and heights. EKXG201ELL151ML25S is manufactured by Chemi-Con and remains ROHS3 compliant.

Compact Form Factor Alternative

UCY2D151MHD offers the smallest diameter (0.492" / 12.50mm) with reduced lead spacing (0.197" / 5.00mm), accommodating space-constrained designs. This configuration requires PCB redesign but delivers superior ripple current performance (1.93 A @ 100 kHz).

Lower Lifetime Tolerance

URZ2D151MHD is suitable only when application requirements permit 1000 Hrs lifetime at 105°C. This part maintains identical mechanical footprint to the original but delivers reduced ripple current capacity (510 mA @ 120 Hz).

Frequently Asked Questions (FAQ)

Q: Can UCY2D151MHD6 replace UAS2D151MHD6 without PCB modification?

A: Yes. UCY2D151MHD6 maintains identical lead spacing (0.295" / 7.50mm), diameter (0.709" / 18.00mm), and mounting type. Height differs by 0.020" (0.50mm), which is within standard PCB clearance tolerances for radial can packages.

Q: What is the primary difference between UAS2D151MHD6 and UCY2D151MHD6?

A: Lifetime rating increases from 2000 Hrs to 12000 Hrs at 105°C. Ripple current capacity approximately doubles across both frequency ranges. Both parts share identical electrical ratings (150 µF, 200 V, ±20%).

Q: Is EKXG201ELL151ML25S (Chemi-Con) compatible with Nichicon UAS2D151MHD6?

A: Yes, for applications where diameter variation (0.630" vs. 0.709") is acceptable. Lead spacing remains identical (0.295" / 7.50mm). EKXG201ELL151ML25S provides 10000 Hrs lifetime and superior ripple current performance. Both are ROHS3 compliant.

Q: Why does UCY2D151MHD have different lead spacing (0.197" vs. 0.295")?

A: This variant represents a different package configuration within the UCY series. Lead spacing reduction requires PCB redesign and is not a direct mechanical substitute for the original UAS2D151MHD6.

Q: Can URZ2D151MHD be used as a long-term substitute?

A: URZ2D151MHD is mechanically compatible but provides only 1000 Hrs lifetime at 105°C, which is 50% lower than the original UAS2D151MHD6. Use only when application duty cycle permits reduced lifetime ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance. REACH status varies: Nichicon UCY series parts are REACH Affected; Nichicon UAS and URZ series, and Chemi-Con EKXG series are REACH Unaffected.

Q: What ripple current improvement does UCY2D151MHD6 provide?

A: Ripple current capacity increases approximately 97% at 120 Hz (460 mA to 910 mA) and 147% at 100 kHz (736 mA to 1.82 A) compared to UAS2D151MHD6.
