UPW2C220MPH Equivalent & Substitute Parts

Part Overview

The UPW2C220MPH is a 22 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The UPW series represents a legacy product line, making alternative sourcing critical for applications requiring this capacitance and voltage rating.

Substitute Part Grouping Explanation

Substitution for the UPW2C220MPH is determined by the following critical parameters:

Capacitance Value: 22 µF (exact match required)
Voltage Rating: Minimum 160 V (equal or higher acceptable)
Package Geometry: Radial, can configuration with matching lead spacing (5.00 mm) and physical dimensions (10.00 mm diameter, 20.00 mm height)
Mounting Interface: Through-hole compatibility
Polarization: Polar (electrolytic)
Operating Temperature Range: -40°C to 105°C minimum

Two substitute categories are identified:

Direct Equivalent: UPW2C220MPD maintains identical electrical specifications and physical form factor, differing only in packaging format and RoHS compliance status.

Upgraded Substitute: EKXG251ELL220MJ20S provides enhanced performance characteristics including higher voltage rating (250 V), extended lifetime (8000 Hrs @ 105°C), and improved ripple current handling, while maintaining identical physical dimensions and lead spacing.

Engineering Selection Recommendations

UPW2C220MPD serves as the direct equivalent for applications requiring identical electrical performance and physical compatibility. This part maintains the same 160 V rating and 5000-hour lifetime specification. Selection of UPW2C220MPD is appropriate when component-level replacement is necessary without design modification. However, this part shares obsolete status with the original component, limiting long-term procurement viability.

EKXG251ELL220MJ20S is recommended for new designs and long-term production applications. This Chemi-Con part provides active product status, ensuring sustained availability and supply chain stability. The elevated voltage rating (250 V) and extended lifetime (8000 Hrs @ 105°C) deliver improved reliability margins. Enhanced ripple current specifications (200 mA @ 120 Hz, 500 mA @ 100 kHz) support higher-stress operating conditions. Both substitute options maintain identical physical form factor and through-hole mounting interface, enabling direct PCB compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can UPW2C220MPD be used as a direct replacement for UPW2C220MPH?

A: Yes. Both parts share identical capacitance (22 µF), voltage rating (160 V), tolerance (±20%), physical dimensions, and lead spacing. The primary difference is packaging format and RoHS compliance status. PCB-level compatibility is complete.

Q: Is EKXG251ELL220MJ20S a suitable substitute despite the higher voltage rating?

A: Yes. The 250 V rating of EKXG251ELL220MJ20S exceeds the 160 V requirement of the original circuit. Higher voltage-rated capacitors operate safely in lower-voltage applications. Physical dimensions and lead spacing are identical, ensuring direct PCB compatibility.

Q: What are the advantages of selecting EKXG251ELL220MJ20S over UPW2C220MPD?

A: EKXG251ELL220MJ20S offers active product status, ensuring long-term availability. The extended lifetime specification (8000 Hrs @ 105°C versus 5000 Hrs) and superior ripple current handling provide enhanced reliability. Both parts maintain identical form factor and mounting interface.

Q: Are there any compatibility concerns with through-hole mounting?

A: No. All three parts are through-hole mounted with identical lead spacing (5.00 mm) and case geometry (10.00 mm diameter, 20.00 mm height). Direct PCB compatibility is maintained without modification.

Q: What is the significance of RoHS compliance status?

A: UPW2C220MPH is RoHS non-compliant, while both UPW2C220MPD and EKXG251ELL220MJ20S are ROHS3 compliant. For applications subject to RoHS regulatory requirements, either substitute part satisfies compliance obligations.
