Substitute Part Grouping Explanation

Substitution of the URZ2A331MHD1CY is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 1000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package style: Radial, Can (exact match required)
• Physical dimensions and lead spacing (exact match required)
• Ripple current ratings at specified frequencies (exact match required)

The URZ2A331MHD variant meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the URZ2A331MHD1CY and URZ2A331MHD are Active products manufactured by Nichicon. The substitute part URZ2A331MHD carries explicit ROHS3 compliance and REACH unaffected status certifications. Selection between these parts should be based on compliance requirements specific to the application and end-use region. Both parts are electrically and mechanically identical across all specified parameters and are suitable for direct substitution in through-hole PCB applications requiring 330 µF, 100 V aluminum electrolytic capacitor functionality.

Frequently Asked Questions (FAQ)

Q: Can URZ2A331MHD be used as a direct replacement for URZ2A331MHD1CY?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including capacitance, voltage rating, tolerance, temperature ratings, physical dimensions, and ripple current performance. Direct substitution is supported.

Q: Are there differences in compliance certifications between these parts?

A: The substitute part URZ2A331MHD explicitly lists ROHS3 compliance and REACH unaffected status. Compliance documentation should be reviewed if regulatory requirements apply to your application.

Q: What are the critical parameters that must match for substitution?

A: Capacitance (330 µF), voltage rating (100 V), tolerance (±20%), lifetime specification (1000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), polarization (Polar), mounting type (Through Hole), package style (Radial, Can), physical dimensions, lead spacing, and ripple current ratings must all match exactly.

Q: Are these parts suitable for high-ripple-current applications?

A: Both parts are rated for 540 mA ripple current at 120 Hz and 810 mA at 10 kHz. Application suitability depends on the specific ripple current requirements of your circuit.

Q: What is the physical footprint compatibility?

A: Both parts share identical through-hole lead spacing of 0.295" (7.50mm), diameter of 0.709" (18.00mm), and maximum seated height of 0.650" (16.50mm). PCB layout compatibility is maintained.
