Substitute Part Grouping Explanation

Substitution eligibility for the UKA1V331MPD1TD is determined by strict equivalence across the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime @ Temperature: 2000 Hrs @ 105°C (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)

All identified substitute parts meet these criteria. Substitutes are categorized as either upgrade parts (enhanced specifications or active product status) or direct equivalents (identical specifications).

Engineering Selection Recommendations

All identified substitute parts satisfy the electrical and mechanical requirements for direct replacement of the UKA1V331MPD1TD. Selection should be based on the following factors:

Product Status Consideration: The ECA-1VHG331B and EEU-HD1V331B are both Active products from Panasonic Electronic Components, providing assurance of continued availability and support. The UVY1V331MPD1TD and UVZ1V331MPD1TD remain in the Nichicon portfolio but carry "Not For New Designs" status, similar to the original part.

Compliance: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Physical Dimensions: The ECA-1VHG331B has a slightly reduced seated height of 0.531" (14.60mm) compared to 0.551" (14.00mm) for the original and other substitutes. This minor difference may be relevant for space-constrained applications.

Inventory Availability: The ECA-1VHG331B offers the highest inventory level at 2638 pieces, followed by UVZ1V331MPD1TD at 2403 pieces.

Frequently Asked Questions (FAQ)

Q: Can UVY1V331MPD1TD be used as a direct replacement for UKA1V331MPD1TD?

A: Yes. Both parts share identical electrical specifications (330 µF, 35 V, ±20%, 2000 Hrs @ 105°C) and mechanical parameters (lead spacing, package type, mounting configuration). The primary difference is the series designation (UVY vs. UKA).

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

A: All parts meet the same electrical and mechanical requirements. The Panasonic parts (ECA-1VHG331B and EEU-HD1V331B) carry Active product status, while the Nichicon alternatives retain "Not For New Designs" status. The ECA-1VHG331B has a marginally reduced height of 0.531" versus 0.551" for other options.

Q: Are there any height restrictions I should consider?

A: The ECA-1VHG331B seated height is 0.531" (14.60mm), while the UKA1V331MPD1TD and most other substitutes measure 0.551" (14.00mm). Verify PCB layout clearance if space is limited.

Q: Do all substitutes support the same ripple current specifications?

A: All substitutes support 350 mA ripple current at 120 Hz. The Panasonic parts (ECA-1VHG331B and EEU-HD1V331B) additionally specify 525 mA at higher frequencies (100 kHz), providing enhanced performance capability.

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

A: The ECA-1VHG331B and EEU-HD1V331B from Panasonic carry Active product status, indicating ongoing manufacturer support and availability assurance compared to the "Not For New Designs" designation of the original and Nichicon alternatives.
