ADA4807-1ARJZ-R2 / ADA4807-1ARJZ-R7:
R2 / R7indicates packaging; same part.
Avago / Broadcom
ACPL-064L-000E / ACPL-064L-500E: Same part, different packaging.
ACPL-5630L-300 / ACPL-5630L: Same part, different packaging.
HSMS2825-TRIG: Can add
-when searching; equivalent toHSMS-2825-TR1G.
HOLT
HI-1573PSI / HI-1573PSIF:
F= lead-free / RoHS compliant.HI-6110POIF / HI-6110PQI: Same part,
F= lead-free.HI-8588PST / HI-8588PSI: Suffixes
1, T, Mindicate different temperature ranges.
IR / Infineon
IRF9310PBF: Remove
PBFto search;PBF= lead-free.TRsuffix does not affect core part number.
Cypress
CY7C1460AV25-200BZXI / CY7C1460KV25-200BZIX:
Xsuffix indicates lead-free.
Suffix
+ / +T:+= lead-free,+T= tape & reel; same core part.
RFMD

Micron
MT29F16G08ABACAWP-IT:C / MT29F16G08ABACAWP-ITZ:C:
Z= lead-free.MT48LC4M32B2P-7IT / MT48LC4M32B2P-7IT:G:
G= lead-free.MT41K256M16TW-107 XIT:P:
XIT/IT= industrial grade; can remove suffix to check part number.MT48LC4M32B2B5-6A XIT:L: Same rule.
Suffix letters usually indicate packaging type, lead content, package style, or industrial/commercial grade.
Suffix numbers may indicate speed grade, voltage, or current; logic differs by manufacturer.
Tape/reel packaging commonly indicated by
T,TR,R,REEL, etc.Lookup tip: Remove suffixes or special symbols (
NOPB,#,TR,/CM.118) to search main part number; packaging and lead status may vary, but the core part is identical.
By following these Semiconductor / Electronic Component Notes, engineers and procurement specialists can quickly identify parts, understand suffix codes, and verify packaging and lead-free information.
