FAQ

What is QB-48FB-EA-03T?

QB-48FB-EA-03T is a Renesas Electronics mechanical drawing document (Rev. 1.00, 2012) specifying the physical dimensions and terminal layout of a 48-pin QFP package. It is not a functional electronic component but a reference for PCB layout and assembly engineering of compatible ICs.

Does QB-48FB-EA-03T have electrical specifications?

No - QB-48FB-EA-03T contains no electrical, thermal, or functional parameters. It is strictly a mechanical reference drawing (R20UT1506XJ0100) defining physical dimensions, tolerances, and terminal geometry for manufacturing and layout use.

Which ICs use the QB-48FB-EA-03T package footprint?

QB-48FB-EA-03T corresponds to Renesas' standard 48-pin 0.5 mm pitch QFP footprint. Specific ICs using this mechanical outline include certain members of the R8C/2x, RL78/G13, and older H8S microcontroller families - verify compatibility via individual device datasheets.

Is QB-48FB-EA-03T a RoHS-compliant package drawing?

Yes - QB-48FB-EA-03T reflects Renesas' standard lead-free QFP construction as defined in 2012. The drawing aligns with RoHS Directive 2011/65/EU requirements for Pb-free terminations and halogen-free molding compounds.

Can QB-48FB-EA-03T be used for solder paste stencil design?

Yes - QB-48FB-EA-03T provides all required dimensions (lead width 0.30 mm, pitch 0.5 mm, body size 7.0 × 7.0 mm) needed to generate accurate solder paste stencils for SMT assembly of compatible ICs using this QFP outline.
