DB426 shows 22.0mm female and 22.2mm male side-profile depth references, 6.3mm and 6.5mm mating projections, and 3.3mm and 3.5mm tail references respectively. The side profiles also identify 13.71mm, 11.17mm and 8.63mm dimensions. The illustrated top-side PCB pattern uses Ø1.00mm contact holes, Ø3.05mm mounting holes, a 5.08mm row-span reference and a 0.25mm stagger reference, with ±0.05mm layout tolerance.
DB426A is available with male or female 15-contact interfaces. The drawing gives a 30.80mm flange length, 24.99mm mounting centres, 16.36mm female and 17.13mm male mating-width references, 2.29mm contact pitch and a 3.96mm mating-row span. Side profiles show a 15.00mm depth reference and 6.10mm mating projection. Tail-position references are 3.08mm, 5.06mm and 7.04mm; the illustrated top-side PCB patterns retain their gender-specific orientation and ±0.05mm tolerance.
MP426B uses 5A machined contacts and right-angle tails. The three tail-position references are 10.1mm, 12.3mm and 14.5mm. Both genders show Ø0.60±0.1mm tails, 4.0mm tail length and a 10.7mm height reference. Female and male mating projections are 5.8mm and 6.0mm respectively, with 10.7mm and 10.9mm side references and a 0.90mm step.
DB426C has a 15-contact female interface, 30.80mm flange length, 24.99mm mounting centres and a 16.40mm mating-width reference. It shows a 5.90mm body-height reference, 3.40mm contact-tail and 2.50mm mounting-tail references, and a 1.50mm side offset. The fixed-screw view identifies 11.8mm and 4.8mm hardware dimensions.
The PCB drawing includes 30.73mm mounting span, 19.05mm and 10.68mm intermediate spans, 0.76mm contact spacing and 0.13mm stagger references. It separately identifies two Ø1.80mm and two Ø0.93mm mounting features, 3.30mm, 2.51mm, 2.00mm and 1.50mm references, and ±0.05mm layout tolerance. Use this slim footprint for DB426C.
Values are in millimetres. A is male mating width, B mounting centres, C flange length, E female mating width and F the indicated contact pitch.

The 78-contact views show four rows with 2.05mm row spacing, a 6.15mm row span and a 15.30mm flange height. The female mating-height reference is 10.80mm and the male reference is 12.20mm. The illustrated 15-contact views instead show a 3.96mm row span and 12.50mm flange height.
DB465 shows 4.4mm tail references, a 10.70mm side reference and a 0.90mm step. Female and male height references are 10.7mm and 11mm respectively. Select the standard, CC, CS, BR or BRJ hardware profile using the model's ordering fields.
DB465A shows 4.10mm tail references, a 9.20mm body-height reference and a 0.70mm step. Its mounting options include BR and BRJ profiles with or without a washer. The two 78-contact detail views are labelled individually as female and male.
