Gracias! That answers the question.

That looks like DZ126T (for "tiny"). While small, both ESU and ZIMO make smaller decoders with much better motor control (and not too expensive).

0.55" x 0.28" x 0.128" (14 x 7.13 x 3.25 mm)  DZ126T  MSRP $34.00

0.32" x 0.28" x 0.10" (8.0 x 7.0 x 2.4mm)  ESU 59826 LokPilot 5 Micro NMRA Decoder 6-pin Wired $28
0.47" x 0.33" x 0.086" (12 x 8.5 x 2.2mm) ZIMO MX621N Sub-Micro Decoder  6-pin $35

At the moment, the smallest non sound is indeed the CT Elektronik Dcx77z at 7.5x5x1.8 mm, but it’s difficult to find these days. Easier to find and also very good is the D&H PD05A at 8x5.2x2.5 mm. Smallest sound decoder is without any doubt the Zimo MS500 at 14x10x2.6 mm.
