Electronic Component Brands and Series Overview

Understanding the different brands and series of electronic components is crucial for procurement and engineering. Each brand has specific suffix conventions, packaging, and lead-free options.

Electronic Component-faith new dawn limited-Original

ON Semiconductor

  • MC14011BDG: Remove suffix to check main part number: MC14011BD. Suffix R/TR indicates packaging; suffix G/2G indicates lead-free.

  • MC79LI5ACD / MC79LI5ACDR2G: Same part, different packaging or lead status.

  • MC series (MC prefix): Last letter D indicates SMD (surface-mount device); letters after D indicate packaging type and lead status.

Xilinx

  • XCF04SVO20C / XCF04SVOG20C: G in the middle indicates lead-free; without G indicates with-lead.

  • Speed suffix: Larger numeric suffix generally indicates higher speed (Xilinx logic).

Altera

  • EPF10K50RC240-3N / EPFI0K50RC240-4N: Suffix -3/-4 indicates speed grade; smaller number = faster speed.

Atmel

  • Suffixes PI / PC indicate legacy versions.

  • Suffixes PU / U indicate new versions; U = industrial-grade lead-free.

  • Suffixes AI / AC have been updated to AU.

Texas Instruments (TI)

  • LM1085IS-ADJ: Remove suffix to check main part: LM1085IS. Suffix X indicates tape & reel packaging.

  • LP5907MFX-3.3/NOPB: Remove /NOPB to check main part; numeric suffix indicates output voltage.

  • IRLML2502TRPBF: Check IRLML2502; TR = packaging, PBF = lead-free.

  • LTC2297IUP#PBF: Check LTC22971UP.

  • LM508SMYX/NOPB: Check LM508SMYX; NOPB = lead-free.

  • OPA2228U / OPA2228UA/2K5: U = industrial-grade; without A = higher grade; UA = commercial-grade.

  • INA126E/250 vs INAI26EA/250: Parameter differences exist between A-suffix and non-A parts.

  • DS90LT012AQMFE/NOPB vs DS90LT012AQMFX/NOPB: Same part, different packaging.

  • LP2985IM5-3.3: Can also check LP2985IM5X-3.3.

NXP

  • TJA1040T/CM.118 vs TJA1040T/CM: .118 indicates packaging; same core part number.

Analog Devices(AD)

  • AD8611ARZ / AD8611ARMZ: Different packages; M = micro lead-frame package.

  • AD9764AR / AD9764ARUZ: Different package types.

  • AD5542ABCPZ-REEL7 / ADS542ABCPZ: Z = lead-free; REEL7 / 500RL7 indicates packaging quantity.

  • AD8541ART-SOT23-5 / AD8541ART: SOT23-5 package; check main part number.

  • ADP3330ART-3.3-SOT-23-6 / ADP3330ART-3.3: Different packages; check main part number.

  • ADA4807-1ARJZ-R2 / ADA4807-1ARJZ-R7: R2 / R7 indicates 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 to HSMS-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, M indicate different temperature ranges.

IR / Infineon

  • IRF9310PBF: Remove PBF to search; PBF = lead-free.

  • TR suffix does not affect core part number.

General Rules for component Lookup

  1. Suffix letters usually indicate packaging type, lead content, package style, or industrial/commercial grade.

  2. Suffix numbers may indicate speed grade, voltage, or current; logic differs by manufacturer.

  3. Tape/reel packaging commonly indicated by T, TR, R, REEL, etc.

  4. 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.
