Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the URZ2C151MHD are classified based on the following substitution criteria:

Upgrade Substitutes maintain identical capacitance (150 µF) and tolerance (±20%) while offering higher voltage ratings or extended lifetime specifications. These parts are electrically compatible in applications where the original voltage specification is exceeded or where enhanced reliability is required.

Similar Substitutes maintain the core electrical specifications (150 µF, 160 V, ±20% tolerance) but differ in physical dimensions, lead spacing, or lifetime ratings. These parts require mechanical compatibility verification before selection.

The key parameters determining substitution eligibility are:

• Capacitance value (150 µF)
• Tolerance (±20%)
• Voltage rating (160 V minimum for direct substitution; higher ratings acceptable)
• Operating temperature range (-40°C ~ 105°C)
• Polarization (Polar)
• Mounting type (Through Hole)
• Package type (Radial, Can)

Engineering Selection Recommendations

UCS2E151MHD (Upgrade Substitute): This Nichicon part provides identical physical dimensions and lead spacing to the URZ2C151MHD while offering a 250 V voltage rating and 10000 Hrs lifetime at 105°C. Selection is appropriate for applications requiring enhanced voltage margin or extended operational life. ROHS3 compliance and REACH unaffected status are maintained.

URZ2D151MHD (Upgrade Substitute): This Nichicon part maintains identical physical dimensions, lead spacing, and lifetime specification while providing a 200 V voltage rating. Selection is appropriate for applications requiring intermediate voltage elevation. ROHS3 compliance is maintained.

UCY2C151MHD3 (Similar Substitute): This Nichicon part maintains identical electrical specifications (150 µF, 160 V, ±20%) and lead spacing (0.295") while offering 12000 Hrs lifetime at 105°C. Physical dimensions differ slightly (0.630" diameter, 0.846" height). Selection requires verification of available board space. ROHS3 compliance is maintained.

EKXG161ELL151ML20S (Similar Substitute): This Chemi-Con part maintains identical electrical specifications (150 µF, 160 V, ±20%) and lead spacing (0.295") while offering 10000 Hrs lifetime at 105°C. Physical dimensions differ (0.630" diameter, 0.787" height). Selection requires verification of available board space. ROHS3 compliance and REACH unaffected status are maintained.

Frequently Asked Questions (FAQ)

Q: Can URZ2C151MHD be replaced with UCS2E151MHD? A: Yes. UCS2E151MHD is a direct physical substitute with identical lead spacing and package dimensions. The higher 250 V rating and extended 10000 Hrs lifetime provide enhanced performance margins. No circuit modifications are required.

Q: What is the difference between URZ2C151MHD and URZ2D151MHD? A: Both parts are Nichicon URZ series capacitors with identical physical dimensions and 1000 Hrs lifetime. URZ2D151MHD provides a 200 V rating compared to 160 V on the URZ2C151MHD. Selection depends on circuit voltage requirements.

Q: Can UCY2C151MHD be used as a direct replacement? A: UCY2C151MHD maintains identical electrical specifications and 160 V rating but differs in physical dimensions and lead spacing. The 0.197" (5.00mm) lead spacing and smaller diameter (0.492") require verification of PCB layout compatibility. The taller height (1.299") must also be confirmed against available board clearance.

Q: What are the mechanical differences between UCY2C151MHD and UCY2C151MHD3? A: Both parts are Nichicon UCY series with identical electrical specifications and 12000 Hrs lifetime. UCY2C151MHD3 has 0.295" lead spacing and 0.630" diameter, matching the original URZ2C151MHD lead spacing. UCY2C151MHD has 0.197" lead spacing and 0.492" diameter. Lead spacing and diameter must be verified against PCB design before selection.

Q: Is EKXG161ELL151ML20S compatible with the original circuit? A: EKXG161ELL151ML20S is a Chemi-Con alternative maintaining identical electrical specifications (150 µF, 160 V, ±20%) and lead spacing (0.295"). Physical dimensions differ slightly (0.630" diameter, 0.787" height). PCB layout verification is required to confirm available space. ROHS3 compliance is maintained.

Q: What lifetime specification should be selected? A: The original URZ2C151MHD specifies 1000 Hrs @ 105°C. Upgrade substitutes offer 10000 Hrs or 12000 Hrs @ 105°C, providing extended operational life. Selection depends on application reliability requirements and thermal operating conditions.
