Frequently Asked Questions (FAQ)
Q: Can UPB1V331MPD be directly replaced with UHE1V331MPD? A: Yes. Both parts share identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), lead spacing (5.00 mm), and can package. UHE1V331MPD has a slightly reduced height (16.00 mm vs. 17.50 mm) and is marked as not-for-new-designs. For new designs, select UHE1V331MPD1CA (active status) or alternative manufacturers.
Q: What is the difference between Rubycon 35YXJ330M10X12.5 and 35ZLH330M10X16? A: Both are Rubycon 330 µF, 35 V radial capacitors with 10000-hour lifetime and active product status. The primary difference is physical height: 35YXJ330M10X12.5 is 14.00 mm tall, while 35ZLH330M10X16 is 17.50 mm tall, matching the original UPB1V331MPD height.
Q: Are Panasonic EEU-FM1V331 and EEU-FM1V331B electrically identical? A: Yes. Both are 330 µF, 35 V capacitors with 4000-hour lifetime, identical electrical specifications, and impedance (26 mOhms). The difference is packaging: EEU-FM1V331 is supplied in bulk, while EEU-FM1V331B is cut tape (CT) for automated assembly.
Q: Which substitute offers the best reliability upgrade? A: Parts with 10000-hour lifetime at 105°C (35YXJ330M10X12.5, 35ZLH330M10X16, EEU-EB1V331) provide extended reliability compared to the original 7000-hour specification.
Q: Is B41888C7337M000 suitable for automotive applications? A: Yes. B41888C7337M000 carries AEC-Q200 rating and operates across -55°C to 105°C, meeting automotive-grade requirements. The original UPB1V331MPD operates only to -40°C.
Q: Can I use a substitute with different physical height? A: Physical height compatibility depends on PCB layout and mechanical constraints. UHV1V331MPD (14.00 mm) and 35YXJ330M10X12.5 (14.00 mm) are the most compact options. UPB1V331MPD, 35ZLH330M10X16, EEU-FM1V331, and EEU-FM1V331B all match the original 17.50 mm height.
Q: What is the inventory status for active alternatives? A: UHE1V331MPD1CA (965 pcs), 35YXJ330M10X12.5 (2519 pcs), 35ZLH330M10X16 (1161 pcs), B41888C7337M000 (6876 pcs), EEU-EB1V331 (3163 pcs), EEU-FM1V331 (75615 pcs), and EEU-FM1V331B (14280 pcs) are available as new original stock.
