Substitute Part Grouping Explanation

Substitution for the UES1E102MHM is determined by the following critical parameters:

Capacitance Value: Must be 1000 µF (exact match required)
Voltage Rating: Must be equal to or greater than 25 V
Tolerance: ±20% (standard for this capacitor class)
Polarization: Bi-Polar configuration
Package Type: Radial, Can format
Lead Spacing: 0.295" (7.50 mm) for PCB compatibility
Case Diameter: 0.630" (16.00 mm) for mechanical fit
Mounting Type: Through Hole

The two qualified substitute parts—Nichicon UEP1V102MHD and Nichicon UVP1V102MHD—meet all mechanical and electrical compatibility requirements. Both parts feature higher voltage ratings (35 V) and improved thermal performance compared to the original UES1E102MHM, making them suitable direct replacements in legacy applications.

Engineering Selection Recommendations

Both substitute parts are ROHS3 compliant and suitable for direct replacement in applications using the UES1E102MHM. Selection between the two substitutes depends on application requirements:

UEP1V102MHD provides an extended operating temperature range (-55°C to 105°C) and maintains REACH Unaffected status, making it suitable for applications requiring broader thermal performance without regulatory complexity.

UVP1V102MHD offers doubled lifetime rating (2000 Hrs @ 85°C versus 1000 Hrs @ 85°C) and higher ripple current handling capability, providing enhanced reliability for demanding applications. This part carries REACH Affected status and should be evaluated against project compliance requirements.

Both parts feature identical mechanical dimensions and lead spacing, ensuring PCB compatibility without layout modifications. The marginal height increase (0.020" / 0.50 mm) is negligible for most through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can UEP1V102MHD or UVP1V102MHD be used as direct replacements for UES1E102MHM?

A: Yes. Both substitute parts match the critical electrical parameters (1000 µF capacitance, ±20% tolerance, bi-polar configuration) and mechanical specifications (lead spacing, case diameter, through-hole mounting). The higher voltage ratings (35 V versus 25 V) provide additional design margin without affecting circuit operation.

Q: What is the difference between UEP1V102MHD and UVP1V102MHD?

A: Both parts share identical capacitance, voltage, tolerance, and package specifications. The primary differences are: UEP1V102MHD supports a wider operating temperature range (-55°C to 105°C) and maintains REACH Unaffected status; UVP1V102MHD provides doubled lifetime rating (2000 Hrs @ 85°C) and higher ripple current capacity but carries REACH Affected status.

Q: Will the substitute parts fit the existing PCB layout?

A: Yes. Lead spacing (0.295" / 7.50 mm) and case diameter (0.630" / 16.00 mm) are identical across all three parts. The height difference is 0.020" (0.50 mm), which is negligible for standard through-hole applications and does not require layout modification.

Q: Are there any compliance considerations when selecting a substitute?

A: All three parts are ROHS3 compliant. UEP1V102MHD and UES1E102MHM are REACH Unaffected, while UVP1V102MHD is REACH Affected. Project-specific compliance requirements should determine final part selection.

Q: What is the significance of the higher voltage rating on the substitute parts?

A: The 35 V rating on both substitutes (versus 25 V on the original) provides additional electrical safety margin. In a 25 V application, the substitute parts operate at reduced stress levels, potentially extending component life and improving circuit reliability.
