UPH2W270MPD Equivalent & Substitute Parts

Part Overview

The UPH2W270MPD is a 27 µF, 450 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Identifying equivalent substitute parts becomes necessary when managing inventory constraints, lead time requirements, or when enhanced performance characteristics such as extended operational lifetime are required for specific application demands.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPH2W270MPD is permissible with the UCP2W270MPD based on the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 27 µF (identical)
• Voltage Rating: 450 V (identical)
• Tolerance: ±20% (identical)
• Polarization: Polar (identical)

Mechanical Parameters (Must Match):

• Lead Spacing: 0.197" (5.00mm) (identical)
• Size / Dimension: 0.394" Dia (10.00mm) (identical)
• Height - Seated (Max): 1.319" (34.60mm) (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial, Can (identical)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant (identical)
• REACH Status: REACH Unaffected (identical)

The UCP2W270MPD differs from the main part only in operational lifetime (10000 Hrs @ 105°C versus 2000 Hrs @ 105°C) and high-frequency ripple current rating (450 mA @ 100 kHz versus 450 mA @ 10 kHz), both representing enhanced performance characteristics that do not compromise compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the UPH2W270MPD and UCP2W270MPD are active products manufactured by Nichicon with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application lifetime requirements and operational frequency characteristics. The UCP2W270MPD provides extended operational lifetime at rated temperature and higher frequency ripple current capability, making it suitable for applications requiring enhanced reliability margins. Both parts maintain identical electrical and mechanical specifications, ensuring direct pin-compatible substitution in through-hole PCB designs. Compliance certifications are equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can the UCP2W270MPD directly replace the UPH2W270MPD in existing designs?

A: Yes. Both parts share identical capacitance (27 µF), voltage rating (450 V), tolerance (±20%), lead spacing (5.00mm), physical dimensions (10.00mm diameter, 34.60mm height), and mounting configuration (through-hole radial). PCB footprints and circuit connections require no modification.

Q: What is the primary difference between these two parts?

A: The UCP2W270MPD offers extended operational lifetime (10000 Hrs @ 105°C) compared to the UPH2W270MPD (2000 Hrs @ 105°C). Additionally, the UCP2W270MPD supports higher frequency ripple current (450 mA @ 100 kHz versus 450 mA @ 10 kHz).

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the UPH2W270MPD and UCP2W270MPD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Does the substitute part require any circuit design modifications?

A: No. The UCP2W270MPD is a direct electrical and mechanical equivalent. No circuit modifications, PCB layout changes, or design alterations are necessary for substitution.

Q: Which part should be selected for long-term reliability applications?

A: The UCP2W270MPD is the appropriate selection for applications requiring extended operational lifetime at elevated temperatures, as it provides 5 times the rated lifetime at 105°C compared to the UPH2W270MPD.
