UCS2E151MHD1TN Equivalent & Substitute Parts

Part Overview

The UCS2E151MHD1TN is a 150 µF, 250 V aluminum electrolytic capacitor manufactured by Nichicon in the UCS series. This radial, through-hole component is rated for 10000 hours at 105°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCS2E151MHD1TN is determined by strict equivalence in the following parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Package / Case: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.295" (7.50 mm) (exact match required)
• Physical Dimensions: 0.709" Dia (18.00 mm) and Height 1.043" (26.50 mm) (exact match required)

The UCY2E151MHD1TN qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. The extended lifetime rating (12000 Hrs @ 105°C versus 10000 Hrs @ 105°C) represents an enhancement that does not compromise compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both UCS2E151MHD1TN and UCY2E151MHD1TN are active products from Nichicon with ROHS3 compliance. The UCY2E151MHD1TN offers an extended operational lifetime of 12000 hours at 105°C compared to the 10000-hour rating of the UCS2E151MHD1TN, while maintaining identical electrical performance and mechanical compatibility. Selection between these parts should be based on application requirements for component longevity and system design margins. Both parts are suitable for direct substitution in through-hole PCB applications requiring 150 µF capacitance at 250 V.

Frequently Asked Questions (FAQ)

Q: Can UCY2E151MHD1TN replace UCS2E151MHD1TN in existing designs?

A: Yes. The UCY2E151MHD1TN maintains identical capacitance, voltage rating, tolerance, operating temperature range, and physical dimensions. The lead spacing and mounting footprint are equivalent, allowing direct PCB substitution without layout modifications.

Q: What is the difference between the UCS and UCY series?

A: Both series are Nichicon aluminum electrolytic capacitors with identical electrical specifications for this part number. The primary difference is the extended lifetime rating of the UCY series (12000 Hrs @ 105°C versus 10000 Hrs @ 105°C).

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The UCY2E151MHD1TN is REACH Affected, while the UCS2E151MHD1TN is REACH Unaffected. Verify REACH compliance requirements for your specific application and region.

Q: Will the extended lifetime of UCY2E151MHD1TN affect circuit performance?

A: No. The extended lifetime rating does not alter electrical performance. Ripple current ratings, ESR characteristics, and capacitance values remain identical across both parts.

Q: Are these parts available in different packaging options?

A: Both parts are supplied in Cut Tape (CT) packaging. The through-hole radial configuration and lead spacing (0.295" / 7.50 mm) are consistent across both part numbers.
