Questions buyers ask
- Can AIP339 replace LM339DR?
- AIP339 is I-CORE's functional equivalent of LM339DR in the same SOP-14 package. Standard parts in this family share the industry pinout, but please compare both datasheets — supply range, timing and absolute maximum ratings — before design-in.
- What is the supply voltage and temperature range of AIP339?
- Supply: 2–30 V. Operating temperature: See datasheet. See the datasheet for full electrical characteristics.
- Is AIP339 in stock and what is the minimum order?
- Yes, it is held in stock in Shenzhen. SMD parts can be ordered from 1 pc; DIP parts ship in full tubes. Minimum order value is US$50 and shipping is charged at cost. Orders ship within 2–3 business days after payment.
- Is it original I-CORE product?
- Yes. We supply factory-original I-CORE (Wuxi I-CORE Electronics) parts in sealed reels and tubes. Our ISO 9001, ISO 14001 and ISO 45001 certificates are shown on the home page; RoHS and REACH test reports are available on request.
