UHD1V271MPD Equivalent & Substitute Parts

Part Overview

The UHD1V271MPD is a 270 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line. The UHD series offers a 3000-hour lifetime rating at 105°C with general-purpose applications in through-hole configurations. Identifying equivalent and substitute parts is necessary for legacy system maintenance, repair operations, and design continuity where original components are unavailable or inventory is depleted.

Substitute Part Grouping Explanation

Substitution eligibility for the UHD1V271MPD is determined by strict equivalence across the following parameters: capacitance (270 µF), voltage rating (35 V), tolerance (±20%), polarization (polar), mounting type (through hole), and package configuration (radial, can). Physical dimensions including lead spacing, case diameter, and height must remain compatible with the original PCB layout. All substitute parts must maintain ROHS3 compliance and operate within the -40°C to 105°C temperature range.

Substitute parts are grouped into four categories based on manufacturer and product status:

Nichicon Series Substitutes (UHE1V271MPD, UHV1V271MPD): Direct manufacturer alternatives with identical electrical specifications but extended or modified lifetime ratings and physical dimensions. These parts share the same lead spacing and case diameter as the original.

Chemi-Con Direct Equivalent (EKZE350ELL271MH20D): Cross-manufacturer equivalent with matching electrical parameters and Active product status, offering improved availability compared to the discontinued UHD series.

Panasonic Active Alternatives (EEU-FR1V271L, EEU-FR1V271, EEU-FR1V271B, EEU-FR1V271LB): Active production parts with superior lifetime ratings (6000–8000 hours) and extended temperature range. Note: Some variants feature different lead spacing (0.197" vs. 0.138") and case diameter (0.394" vs. 0.315"), requiring PCB layout verification.

Cornell Dubilier and Rubycon Equivalents (277KXM035M, 35ZLG270MEFC8X20): Active production alternatives with matching core specifications and extended operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

For direct PCB replacement without layout modification, select parts with matching lead spacing (0.138"), case diameter (0.315"), and height specifications. UHE1V271MPD, UHV1V271MPD, EKZE350ELL271MH20D, 277KXM035M, EEU-FR1V271L, and 35ZLG270MEFC8X20 meet these dimensional requirements.

For applications where extended component lifetime is beneficial, EEU-FR1V271L (8000 hours) and EEU-FR1V271LB (8000 hours) offer superior reliability compared to the original 3000-hour specification.

All listed substitutes maintain ROHS3 compliance, ensuring regulatory compatibility with existing designs. Parts with Active product status (EKZE350ELL271MH20D, 277KXM035M, EEU-FR1V271L, EEU-FR1V271, EEU-FR1V271B, EEU-FR1V271LB, 35ZLG270MEFC8X20) provide long-term supply chain stability and are preferred for new procurement.

Frequently Asked Questions (FAQ)

Q: Can EEU-FR1V271 and EEU-FR1V271B be used as direct replacements for UHD1V271MPD?

A: These parts are electrically equivalent but have different physical dimensions. Lead spacing is 0.197" (5.00mm) versus 0.138" (4.60mm), and case diameter is 0.394" (10.00mm) versus 0.315" (8.00mm). Direct PCB substitution is not possible without layout modification.

Q: What is the difference between EEU-FR1V271L and EEU-FR1V271LB?

A: Both parts have identical electrical specifications and 8000-hour lifetime ratings. The primary difference is packaging: EEU-FR1V271L is supplied in Bulk, while EEU-FR1V271LB is supplied in Cut Tape (CT). Electrical performance and physical dimensions are identical.

Q: Why do some substitutes have different heights despite matching case diameter?

A: Height variation reflects different internal construction and winding configurations among manufacturers. All listed parts maintain the same lead spacing and case diameter for PCB compatibility, but height differences may affect clearance in space-constrained applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance, ensuring compatibility with regulatory requirements for electronic equipment manufacturing and disposal.

Q: Which substitute offers the best long-term availability?

A: Parts with Active product status provide the longest supply chain stability. EEU-FR1V271L, EEU-FR1V271LB, EKZE350ELL271MH20D, 277KXM035M, and 35ZLG270MEFC8X20 are all in active production and recommended for new procurement.
