Substitute Part Grouping Explanation

Substitution for the UPW2E100MPH is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

Capacitance: 10 µF (exact match required)
Voltage Rating: 250 V minimum (equal or higher acceptable)
Tolerance: ±20% (matching or tighter tolerance acceptable)
Lead Spacing: 0.197" (5.00 mm) (exact match required for PCB compatibility)
Package Diameter: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

Substitution Categories:

Direct Equivalents maintain identical electrical specifications and physical dimensions, differing only in packaging format or minor compliance updates.

Upgraded Alternatives provide higher voltage ratings or extended lifetime ratings while maintaining identical capacitance, tolerance, lead spacing, and package dimensions. These are suitable when circuit design permits higher voltage operation.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

UPW2E100MPD is the direct equivalent to UPW2E100MPH, maintaining identical electrical and mechanical specifications while providing ROHS3 compliance. This part is preferred for applications requiring exact parameter matching and is available in bulk packaging.

For Extended Lifetime Applications:

250LLE10MEFC10X12.5 (Rubycon) and EKXF251ELL100MJC5S (Chemi-Con) both provide 15000 Hrs lifetime at 105°C compared to the original 5000 Hrs specification. Both maintain 250 V rating, 10 µF capacitance, and identical lead spacing. These parts are active products with ROHS3 compliance. Physical height is reduced (14.50 mm and 14.00 mm respectively versus 20.00 mm), which may provide PCB layout advantages in space-constrained designs.

For Higher Voltage Operation:

UPW2F100MPD (Nichicon, 315 V) and EKXG401ELL100MJ20S (Chemi-Con, 400 V) provide elevated voltage ratings while maintaining 10 µF capacitance and identical lead spacing. These upgrades are suitable when circuit design permits higher voltage operation and require ROHS3 compliance.

Compliance Consideration:

All substitute parts listed provide ROHS3 compliance, addressing the RoHS non-compliant status of the original UPW2E100MPH.

Frequently Asked Questions (FAQ)

Q: Can UPW2E100MPD be used as a direct replacement for UPW2E100MPH?

A: Yes. UPW2E100MPD is electrically and mechanically identical to UPW2E100MPH, with the primary difference being ROHS3 compliance. Both maintain 10 µF capacitance, 250 V rating, ±20% tolerance, 5000 Hrs lifetime at 105°C, and identical physical dimensions including 0.197" lead spacing and 0.787" maximum height.

Q: What is the advantage of using 250LLE10MEFC10X12.5 or EKXF251ELL100MJC5S?

A: Both parts provide extended lifetime ratings of 15000 Hrs at 105°C compared to the original 5000 Hrs specification, offering improved reliability for long-term applications. Both maintain identical capacitance, voltage rating, tolerance, and lead spacing. Physical height is reduced, which may benefit PCB layout in space-constrained designs.

Q: Can higher voltage rated parts (UPW2F100MPD or EKXG401ELL100MJ20S) be used in place of the UPW2E100MPH?

A: Higher voltage rated parts are electrically compatible when circuit design permits. UPW2F100MPD (315 V) and EKXG401ELL100MJ20S (400 V) maintain identical capacitance, tolerance, and lead spacing. Substitution is valid only when the circuit voltage requirement does not exceed the original 250 V specification, as overvoltage operation is not permitted.

Q: Are all substitute parts through-hole mounted with identical lead spacing?

A: Yes. All substitute parts listed maintain 0.197" (5.00 mm) lead spacing and through-hole mounting, ensuring PCB footprint compatibility with the original UPW2E100MPH design.

Q: What is the difference between obsolete and active product status?

A: Obsolete parts are no longer manufactured and have limited availability. Active parts are currently in production. For new designs or long-term supply requirements, active parts such as 250LLE10MEFC10X12.5, EKXF251ELL100MJC5S, and EKXG401ELL100MJ20S are preferred.
