Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

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

Secondary Considerations:

• Lead spacing, diameter, and height must accommodate the PCB layout
• Lifetime rating and ripple current specifications may vary based on application demands
• Manufacturer and series designation may differ while maintaining electrical equivalence

Substitute Categories:

Upgrade Substitute (Higher Voltage Rating):

• UCS2E151MHD: 250 V rated (higher voltage margin), 10000 Hrs @ 105°C lifetime

Direct Equivalents (Same Voltage, Different Manufacturers/Series):

• UCY2D151MHD: Nichicon UCY series, 12000 Hrs @ 105°C, lead spacing 0.197" (5.00 mm)
• UCY2D151MHD3: Nichicon UCY series, 12000 Hrs @ 105°C, diameter 0.630" (16.00 mm)
• UCY2D151MHD6: Nichicon UCY series, 12000 Hrs @ 105°C, height 0.846" (21.50 mm)
• EKXG201ELL151ML25S: Chemi-Con KXG series, 10000 Hrs @ 105°C, diameter 0.630" (16.00 mm)

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (Same Footprint): UCY2D151MHD6 is the preferred substitute when identical lead spacing (0.295"), diameter (0.709"), and height (1.043") are required. This part maintains full mechanical and electrical compatibility with the URZ2D151MHD while offering extended lifetime (12000 Hrs vs. 1000 Hrs @ 105°C) and higher ripple current capacity. Both parts are ROHS3 compliant.

For Enhanced Performance with Layout Flexibility: UCS2E151MHD provides higher voltage rating (250 V vs. 200 V), extended lifetime (10000 Hrs), and significantly improved ripple current handling (1.94 A @ 100 kHz). Lead spacing and diameter match the original part. This upgrade is suitable when circuit design permits higher voltage components and improved thermal performance is desired.

For Maximum Availability and Extended Lifetime: UCY2D151MHD3 offers the highest inventory level (100100 units) with 12000-hour lifetime rating. Mechanical dimensions differ slightly (diameter 0.630" vs. 0.709"), requiring PCB layout verification. Lead spacing remains compatible (0.295").

For Cross-Manufacturer Compatibility: EKXG201ELL151ML25S (Chemi-Con KXG series) provides equivalent electrical performance with 10000-hour lifetime and ROHS3 compliance. Mechanical dimensions differ (diameter 0.630", height 0.984"), necessitating layout confirmation.

All substitute parts maintain ROHS3 compliance and are suitable for general purpose applications within the specified operating temperature range (-40°C to 105°C).

Frequently Asked Questions (FAQ)

Q: Can UCY2D151MHD be used as a direct replacement for URZ2D151MHD? A: UCY2D151MHD is electrically equivalent but has different mechanical dimensions. Lead spacing is 0.197" (5.00 mm) versus 0.295" (7.50 mm), and the can diameter is 0.492" (12.50 mm) versus 0.709" (18.00 mm). PCB layout must be verified before substitution.

Q: What is the advantage of UCS2E151MHD over the original URZ2D151MHD? A: UCS2E151MHD has a higher voltage rating (250 V vs. 200 V), extended lifetime (10000 Hrs vs. 1000 Hrs @ 105°C), and superior ripple current capacity (1.94 A @ 100 kHz vs. 816 mA @ 10 kHz). Mechanical dimensions are identical, enabling direct substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts are ROHS3 compliant. The original URZ2D151MHD is also ROHS3 compliant.

Q: Which substitute offers the best availability? A: UCY2D151MHD3 has the highest inventory level at 100100 units. However, its diameter (0.630") differs from the original (0.709"), requiring PCB layout verification.

Q: Can I use a 250 V rated capacitor in a 200 V circuit? A: Yes. UCS2E151MHD is rated for 250 V and can be used in circuits designed for 200 V operation. The higher voltage rating provides additional safety margin and does not negatively affect circuit performance.

Q: What is the difference between UCY2D151MHD, UCY2D151MHD3, and UCY2D151MHD6? A: All three are Nichicon UCY series capacitors with identical electrical specifications (150 µF, 200 V, ±20%, 12000 Hrs @ 105°C). They differ in mechanical dimensions: UCY2D151MHD has lead spacing 0.197" and diameter 0.492"; UCY2D151MHD3 has lead spacing 0.295" and diameter 0.630"; UCY2D151MHD6 has lead spacing 0.295", diameter 0.709", and reduced height (0.846" vs. 1.043").

Q: Is EKXG201ELL151ML25S from a different manufacturer compatible? A: Yes, EKXG201ELL151ML25S (Chemi-Con) is electrically equivalent with matching capacitance, voltage, tolerance, and operating temperature range. Mechanical dimensions differ (diameter 0.630", height 0.984"), requiring PCB layout confirmation before use.
