Nichicon UPS2W100MHD 10 µF 450 V Aluminum Electrolytic Capacitor Equivalent & Substitute Parts

Part Overview

The Nichicon UPS2W100MHD is a 10 µF, 450 V aluminum electrolytic capacitor in radial, can package configuration rated for 3000 hours at 105°C. This part carries obsolete product status, making equivalent and substitute parts necessary for ongoing maintenance, repair, and legacy system support. The UPS series represents an earlier generation design with lower lifetime rating compared to current production alternatives from both Nichicon and other manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the UPS2W100MHD is determined by the following mandatory parameters:

Capacitance: 10 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Operating Temperature Range: -25°C to 105°C (exact match required)

Substitute parts are grouped into two categories:

Direct Nichicon Series Substitutes maintain identical electrical specifications and mechanical footprint compatibility with the original UPS2W100MHD. These include the UPW2W100MHD (8000 Hrs @ 105°C) and UCA2W100MHD (12000 Hrs @ 105°C), which offer extended lifetime ratings while preserving the same capacitance, voltage, tolerance, and temperature range.

Cross-Manufacturer Substitutes from Panasonic Electronic Components meet all mandatory electrical and mechanical parameters. The ECA-2WHG100, ECA-2WHG100B, ECA-2WHG100E, EEU-EB2W100, EEU-ED2W100, and EEU-EE2W100 series all provide 10 µF, 450 V, ±20% tolerance in radial can packages with through-hole mounting and -25°C to 105°C operating range. Lifetime ratings vary from 2000 to 10000 hours at 105°C depending on the specific series selected.

Additional Nichicon alternatives include UVY2W100MPD and UVZ2W100MHD, both rated for 2000 hours at 105°C with identical electrical specifications but different physical dimensions.

Engineering Selection Recommendations

For Direct Replacement with Identical Footprint: The UPW2W100MHD provides the closest mechanical compatibility to the UPS2W100MHD, maintaining the 0.295" (7.50 mm) lead spacing and 0.630" (16.00 mm) diameter. This part is obsolete but offers 8000 hours lifetime at 105°C, a significant improvement over the original 3000 hours. Height is reduced from 1.063" to 0.984", which may require PCB layout verification in space-constrained applications.

For Extended Lifetime with Compact Footprint: The UCA2W100MHD delivers 12000 hours at 105°C with reduced physical dimensions (0.492" diameter, 0.197" lead spacing). This Nichicon part is obsolete but represents a higher-performance alternative suitable for applications requiring extended operational life. PCB redesign is necessary due to different lead spacing and diameter.

For Active Production Status: Panasonic EEU-EE2W100 and EEU-ED2W100 are both active products rated for 10000 hours at 105°C. Both meet ROHS3 compliance and maintain the 0.197" (5.00 mm) lead spacing and 0.492" (12.50 mm) diameter. The EEU-EE2W100 offers the highest ripple current capability (490 mA @ 100 kHz) among all substitutes. The EEU-ED2W100 provides a slightly reduced height of 0.787" (20.00 mm) compared to 0.866" for most alternatives.

For Immediate Availability: Panasonic EEU-EB2W100 is active with 12943 units in stock, offering 5000 hours at 105°C with identical footprint to the EEU-EE2W100 and EEU-ED2W100 series. This represents a balanced option between lifetime rating and current availability.

All substitute parts maintain ROHS3 compliance and are suitable for general-purpose applications within the specified -25°C to 105°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the UPS2W100MHD be replaced with a part having different lead spacing?

A: Yes, if PCB layout permits redesign. The UPS2W100MHD uses 0.295" (7.50 mm) lead spacing. Substitutes with 0.197" (5.00 mm) lead spacing (UCA2W100MHD, UVY2W100MPD, UVZ2W100MHD, and all Panasonic ECA and EEU series) require PCB modification. The UPW2W100MHD maintains identical 0.295" lead spacing for direct PCB compatibility.

Q: What is the difference between Nichicon and Panasonic substitutes?

A: Both manufacturers provide 10 µF, 450 V, ±20% tolerance radial can capacitors meeting all mandatory electrical specifications. Nichicon substitutes (UPW, UCA, UVY, UVZ series) are obsolete or not recommended for new designs. Panasonic substitutes (ECA-2WHG, EEU-EB, EEU-ED, EEU-EE series) carry active product status, ensuring ongoing availability and support. Panasonic parts offer lifetime ratings from 2000 to 10000 hours at 105°C.

Q: Does lifetime rating affect substitution eligibility?

A: No. Lifetime rating is not a mandatory substitution parameter. The UPS2W100MHD is rated for 3000 hours at 105°C. Substitutes with higher lifetime ratings (8000, 10000, or 12000 hours) are fully compatible and represent performance improvements. Substitutes with lower lifetime ratings (2000 hours) are also electrically and mechanically compatible but may not meet application requirements for extended service life.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance status, matching the original UPS2W100MHD. REACH status is unaffected for all parts.

Q: What packaging options are available for substitutes?

A: The UPS2W100MHD is supplied in bulk packaging. Panasonic ECA-2WHG100B is available in Tape & Box (TB) packaging. All other substitutes are supplied in bulk packaging. Packaging selection does not affect electrical or mechanical compatibility.

Q: Which substitute offers the best ripple current performance?

A: The EEU-EE2W100 provides the highest ripple current capability at 490 mA @ 100 kHz, compared to the original UPS2W100MHD at 120 mA @ 10 kHz. The EEU-ED2W100 offers 350 mA @ 100 kHz. Higher ripple current capability indicates improved performance in high-frequency switching applications.

Q: Can the UPS2W100MHD be used in new designs?

A: No. The UPS2W100MHD carries obsolete product status. For new designs, active production alternatives such as Panasonic EEU-EE2W100, EEU-ED2W100, or EEU-EB2W100 are recommended to ensure long-term supply chain continuity and manufacturer support.
