Substitute Part Grouping Explanation

Substitution of the Nichicon UPT2D101MHD is determined by strict equivalence in the following electrical parameters:

Capacitance: 100 µF (exact match required)
Voltage Rating: 200 V (exact match required)
Tolerance: ±20% (exact match required)
Operating Temperature Range: -25°C ~ 105°C (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Substitute parts may differ in the following parameters without affecting functional equivalence:

Lifetime @ 105°C: Extended lifetimes (5000 Hrs, 10000 Hrs, 12000 Hrs) provide improved reliability margins
Lead Spacing: Variations accommodate different PCB layouts (5.00 mm vs. 7.50 mm)
Case Diameter: Variations accommodate different spatial constraints (12.50 mm, 16.00 mm, 18.00 mm)
Height: Variations accommodate different spatial constraints
Ripple Current Ratings: Higher ratings indicate improved thermal performance
Manufacturer: Nichicon and Panasonic Electronic Components both produce compliant alternatives
Product Status: Active parts are preferred; Obsolete parts remain functionally equivalent but may have limited availability

Engineering Selection Recommendations

All listed substitute parts maintain full electrical equivalence to the Nichicon UPT2D101MHD across the critical parameters of capacitance, voltage rating, tolerance, and operating temperature range. All parts are ROHS3 compliant and suitable for general-purpose applications.

For applications requiring extended operational lifetime, the Panasonic EEU-ED2D101, EEU-ED2D101S, and EEU-EE2D101S series offer 10000-hour ratings at 105°C, compared to the 5000-hour rating of the primary part. The Nichicon UCA2D101MHD6 provides 12000-hour lifetime but carries Obsolete product status.

For applications with strict spatial constraints, the Panasonic EEU-ED2D101S and EEU-EE2D101S offer reduced height profiles (20.00 mm and 22.00 mm respectively) while maintaining equivalent electrical performance. The Panasonic ECA-2DHG101 provides a compact 27.00 mm height but operates at a reduced 2000-hour lifetime rating.

For applications requiring the smallest case diameter, the primary part UPT2D101MHD maintains a 12.50 mm diameter. All Panasonic substitutes use 16.00 mm or 18.00 mm case diameters. The Nichicon UCA2D101MHD6 uses an 18.00 mm diameter.

All substitute parts are available in Active product status except UCA2D101MHD6, which is Obsolete. Active parts are recommended for new designs and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Nichicon UPT2D101MHD with a Panasonic part?

A: Yes. All listed Panasonic parts (EEU-EB2D101, EEU-EB2D101S, EEU-ED2D101, EEU-ED2D101S, EEU-EE2D101S, and ECA-2DHG101) maintain electrical equivalence in capacitance, voltage rating, tolerance, and operating temperature range. Physical dimensions differ; verify PCB layout compatibility before substitution.

Q: What is the difference between parts with and without the "S" suffix?

A: The "S" suffix indicates a different case diameter. Parts without "S" (EEU-EB2D101, EEU-ED2D101) use 16.00 mm diameter cases. Parts with "S" (EEU-EB2D101S, EEU-ED2D101S, EEU-EE2D101S) use 18.00 mm diameter cases. Electrical performance is equivalent; physical fit on the PCB differs.

Q: Why does the Panasonic ECA-2DHG101 have a lower lifetime rating?

A: The ECA-2DHG101 is rated for 2000 hours at 105°C, compared to 5000 hours for the primary part. This part remains electrically equivalent but provides reduced operational lifetime margin. Use only when spatial constraints require the compact 27.00 mm height and reduced lifetime is acceptable for the application.

Q: Can I use the Nichicon UCA2D101MHD6 as a substitute?

A: The UCA2D101MHD6 is electrically equivalent and offers extended 12000-hour lifetime. However, it carries Obsolete product status, indicating limited future availability. Use only when extended lifetime justifies supply chain risk, or when existing inventory must be consumed.

Q: What are the lead spacing differences, and do they matter?

A: The primary part UPT2D101MHD uses 5.00 mm lead spacing. All Panasonic substitutes and the Nichicon UCA2D101MHD6 use 7.50 mm lead spacing. Lead spacing determines PCB hole pattern compatibility. Verify your PCB design accommodates the substitute part's lead spacing before installation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the primary part.

Q: Which substitute offers the best ripple current performance?

A: The Panasonic EEU-EE2D101S provides the highest ripple current ratings: 666 mA at 120 Hz and 1.665 A at 100 kHz. This part is suitable for applications requiring superior thermal performance under high-frequency ripple current conditions.
