Frequently Asked Questions (FAQ)

Q: Can URS1V331MPD1TD directly replace UVK1V331MPD1TD? A: Yes. URS1V331MPD1TD is a parametric equivalent with identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), temperature range (-40°C ~ 85°C), and mechanical dimensions. The primary difference is Active product status versus Not For New Designs. Both parts are electrically and mechanically interchangeable.

Q: What is the difference between Nichicon UVK and URS series? A: Both series share identical electrical specifications and mechanical packaging. The URS series represents Nichicon's current active product line, while UVK is superseded. Selection between them depends on procurement availability and design phase requirements.

Q: Are Panasonic ECA-1VM331B and Nichicon UVK1V331MPD1TD compatible? A: Yes, with one mechanical consideration. ECA-1VM331B has a seated height of 0.531" (14.60 mm) compared to UVK1V331MPD1TD at 0.551" (14.00 mm). This 0.020" difference is within acceptable tolerance for most PCB layouts. All other parameters—capacitance, voltage, tolerance, lead spacing, case diameter, and mounting type—are identical.

Q: Which substitute offers the longest operational lifetime? A: 35ZLH330MEFCT810X12.5 (Rubycon ZLH series) provides 10000 Hrs @ 105°C, compared to 2000 Hrs @ 85°C for the original UVK1V331MPD1TD. This represents a five-fold increase in rated lifetime at elevated temperature.

Q: Can I use a substitute with extended temperature range in place of UVK1V331MPD1TD? A: Yes. Parts with extended temperature ranges (-55°C ~ 105°C) are backward compatible with the original operating range (-40°C ~ 85°C). Extended range capability does not compromise performance within the original specification window.

Q: What is the inventory status for active alternatives? A: URS1V331MPD1TD (Nichicon, Active) has 744 Pcs available. 35ZLH330MEFCT810X12.5 (Rubycon, Active) has the highest inventory at 203963 Pcs. ECA-1VM331B (Panasonic, Active) has 17243 Pcs available. All three represent readily available alternatives.

Q: Are all listed substitutes ROHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the original UVK1V331MPD1TD specification.

Q: What packaging formats are available for these substitutes? A: Most substitutes are supplied in Cut Tape (CT) format. ECA-1VM331B is available in Tape & Box (TB) format. Packaging format does not affect electrical or mechanical compatibility; it relates only to procurement and handling procedures.
