Substitute Part Grouping Explanation

Substitution eligibility for the UVZ1V102MHD1TO is determined by strict alignment of the following parameters:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.492" (12.50 mm) (exact match required)
Height: 0.866" (22.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in lifetime rating, ripple current capacity, and product status are noted but do not preclude functional substitution in applications where the baseline specifications are satisfied.

Engineering Selection Recommendations

UPA1V102MHD1TO (Nichicon) is the preferred upgrade substitute. This part maintains all core electrical and mechanical specifications while offering extended lifetime (5000 hours at 105°C versus 2000 hours) and higher ripple current capacity. UPA1V102MHD1TO carries Active product status, ensuring long-term availability and supply chain stability. This part is suitable for new designs and ongoing production.

UVY1V102MHD1TO (Nichicon) and ECA-1VHG102B (Panasonic Electronic Components) are parametric equivalents that match all baseline specifications of the UVZ1V102MHD1TO. Both parts are ROHS3 compliant and suitable for direct replacement in legacy applications. UVY1V102MHD1TO maintains Nichicon manufacturing consistency, while ECA-1VHG102B provides cross-manufacturer compatibility. Both carry Not For New Designs or equivalent status considerations.

For applications requiring extended operational life or higher ripple current handling, UPA1V102MHD1TO is the recommended selection. For direct legacy replacement where specifications are identical, UVY1V102MHD1TO or ECA-1VHG102B are acceptable alternatives.

Frequently Asked Questions (FAQ)

Q: Can UPA1V102MHD1TO be used as a direct replacement for UVZ1V102MHD1TO?

A: Yes. UPA1V102MHD1TO meets all core electrical and mechanical parameters: 1000 µF capacitance, 35 V rating, ±20% tolerance, -55°C to 105°C operating range, identical lead spacing (5.00 mm), case diameter (12.50 mm), and height (22.00 mm). The extended lifetime rating (5000 hours versus 2000 hours at 105°C) and higher ripple current capacity represent performance improvements, not incompatibilities.

Q: What is the difference between UVY1V102MHD1TO and UVZ1V102MHD1TO?

A: Both parts are Nichicon aluminum electrolytic capacitors with identical electrical specifications: 1000 µF, 35 V, ±20% tolerance, 2000 hours at 105°C lifetime, and matching mechanical dimensions. The primary difference is series designation (UVY versus UVZ). Both are classified as Not For New Designs. Substitution is direct.

Q: Is ECA-1VHG102B compatible with through-hole PCB layouts designed for UVZ1V102MHD1TO?

A: Yes. ECA-1VHG102B is a Panasonic radial aluminum electrolytic capacitor with identical lead spacing (5.00 mm), case diameter (12.50 mm), and height (22.00 mm). Through-hole mounting compatibility is confirmed. All electrical parameters match the baseline specification.

Q: Why does UPA1V102MHD1TO have higher ripple current ratings?

A: UPA1V102MHD1TO is rated for 1.418 A at 120 Hz and 1.89 A at 100 kHz, compared to 810 mA and 931.5 mA respectively for UVZ1V102MHD1TO. This reflects improved internal design and materials in the UPA series. Higher ripple current capacity does not affect substitution eligibility; it indicates enhanced performance margin in applications with elevated ripple current demands.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. UVZ1V102MHD1TO, UPA1V102MHD1TO, UVY1V102MHD1TO, and ECA-1VHG102B are all ROHS3 compliant, confirming restriction of hazardous substances in accordance with applicable regulations.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the part is in mature or obsolescence phase and is not recommended for new product development. However, it remains suitable for maintenance, repair, and legacy system support. UPA1V102MHD1TO and ECA-1VHG102B carry Active status, making them appropriate for both new designs and ongoing production applications.
