Substitute Part Grouping Explanation

Substitute parts for the EKXG201ELL151ML25S are qualified based on the following criteria:

Electrical Equivalence Requirements:

• Capacitance: 150 µF (exact match)
• Voltage Rating: 200 V (exact match)
• Tolerance: ±20% (exact match)
• Operating Temperature Range: -40°C ~ 105°C (exact match)
• Polarization: Polar (exact match)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole (exact match)
• Package / Case: Radial, Can (exact match)
• Lead Spacing: 0.295" (7.50mm) (exact match for primary substitutes)

Compliance Requirements:

• RoHS3 Compliant (all substitutes meet this requirement)

The substitute parts identified are manufactured by Nichicon and maintain identical electrical specifications. Physical dimensions and ripple current ratings may vary within acceptable tolerances for the application category. Lifetime ratings differ among substitutes but all exceed minimum operational requirements for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

UCY2D151MHD3 and UCY2D151MHD6 are the preferred substitutes for the EKXG201ELL151ML25S. Both parts maintain identical lead spacing (0.295" / 7.50mm) and diameter (0.630" / 16.00mm), ensuring direct mechanical compatibility with existing PCB layouts. Both are ROHS3 compliant and Active status. UCY2D151MHD3 offers extended lifetime (12000 Hrs @ 105°C versus 10000 Hrs), providing enhanced reliability margin. UCY2D151MHD6 provides the most compact height profile (0.846" / 21.50mm) while maintaining all electrical specifications.

Secondary Substitute (Dimensional Variation):

UCY2D151MHD is ROHS3 compliant and Active status with 12000 Hrs lifetime rating. This part features a reduced lead spacing (0.197" / 5.00mm) and smaller diameter (0.492" / 12.50mm), requiring PCB layout modification. Height is significantly increased (1.457" / 37.00mm), which may present clearance constraints in compact designs.

Limited Substitute (Reduced Lifetime):

URZ2D151MHD is ROHS3 compliant and Active status but rated for only 1000 Hrs @ 105°C, representing a substantial reduction in operational lifetime compared to the original part (10000 Hrs). This part is suitable only for applications with minimal thermal stress or short operational cycles. Ripple current ratings are significantly lower across all frequency ranges.

Frequently Asked Questions (FAQ)

Q: Can UCY2D151MHD be used as a direct replacement for EKXG201ELL151ML25S?

A: UCY2D151MHD matches all electrical specifications but has different mechanical dimensions. Lead spacing is reduced from 0.295" to 0.197", and diameter is reduced from 0.630" to 0.492". Direct PCB substitution is not possible without layout modification. Height is also increased to 1.457", which may create clearance issues.

Q: Which substitute offers the best reliability upgrade?

A: UCY2D151MHD3 and UCY2D151MHD6 both provide 12000 Hrs @ 105°C lifetime rating, compared to 10000 Hrs for the original part. Both maintain identical lead spacing and diameter. UCY2D151MHD3 has a height of 1.043", while UCY2D151MHD6 has a height of 0.846", offering the most compact profile.

Q: Is URZ2D151MHD suitable for high-reliability applications?

A: No. URZ2D151MHD is rated for only 1000 Hrs @ 105°C, which is significantly lower than the original 10000 Hrs rating. This part is suitable only for applications with minimal thermal stress or short operational cycles. Ripple current capacity is also substantially reduced.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All identified substitute parts (UCY2D151MHD, UCY2D151MHD3, UCY2D151MHD6, and URZ2D151MHD) are ROHS3 compliant, matching the compliance status of the original EKXG201ELL151ML25S.

Q: What is the impact of different ripple current ratings?

A: Ripple current capacity determines the maximum AC current the capacitor can handle without exceeding temperature limits. UCY2D151MHD3 and UCY2D151MHD6 provide ripple current ratings comparable to or exceeding the original part. URZ2D151MHD provides significantly reduced ripple current capacity (510 mA @ 120 Hz versus 840 mA), limiting its use in high-ripple-current applications.

Q: Are all substitutes available in the same packaging format?

A: Yes. All substitute parts are through-hole radial can packages, matching the original EKXG201ELL151ML25S packaging format. However, physical dimensions (diameter and height) vary among substitutes, requiring verification of PCB clearance and mounting space.
