Frequently asked questions

Is Seiko Instruments still in business?

Seiko Instruments semiconductors (S-xxxx voltage detectors, LDOs, EEPROM) became ABLIC in 2016.

Can I still buy Seiko Instruments parts?

Yes. PartnerSemi quotes Seiko Instruments part numbers, including obsolete and end-of-life parts and parts with old Seiko Instruments markings. Send the part number and quantity; we reply with price, lead time, date code and origin. We are an independent distributor, not an authorized Seiko Instruments or ABLIC distributor.
