The MP422B/C current entries do not establish a 40A per-contact capability. No power-contact rating is transferred to the standard signal-pin layouts. Unresolved temperature entries do not establish an approved operating range. Certification numbers, UL use-group ratings and storage limits for other models are unspecified.

Hardware abbreviations identify the drawings rather than universal thread standards. Match the inner and outer thread specifications separately. Do not treat all listed hardware combinations as available on every model.

|---|---|---|---|---|
| 9 | 17.90 | 24.99 | 30.80 or 30.84 by model | 16.33 |
| 15 | 26.50 | 33.32 | 39.14 | 24.66 |
| 25 | 40.00 | 47.04 | 53.04 | 38.38 |

For DB421J, DB422, DB422A, MP422B, MP422C, MP422V and MP422W, C for 9 contacts is 30.80mm; A and B tolerance is ±0.2mm and C tolerance ±0.3mm. DB421J does not tabulate D. DB425, DB425B, DB425C and MP425D specify 30.84mm for 9 contacts, while DB425A specifies 30.80mm; these right-angle tables use ±0.2mm for A, B and C. D has no displayed tolerance. Standard two-row interface pitch is 2.77mm horizontally and 2.84mm between rows. Male and female interface heights differ.
DB421J is a male straight version with 3.3mm tail reference. Its separate 50-contact outline shows 67.04mm mounting-hole spacing, 64.50mm shell reference and 51.00mm contact span, with 1.985mm stagger and a three-row arrangement. DB422 and MP422V provide straight male/female layouts with CC, CS, BR and BRJ hardware drawings. DB422A and MP422W add the illustrated fork and washer arrangements; their outline includes 4.10mm and 10.00mm rear references. These are model-specific mechanical dimensions, not equivalent mounting heights.
The female and male forms have different face-to-tail references. MP422B shows 16.10mm and 16.30mm overall side references; MP422C instead specifies 10.10mm to the indicated tail datum. MP422C illustrates Ø0.60±0.1mm tails. Select the exact suffix rather than transferring a footprint from the similar product photograph.
These right-angle connectors have distinct shield and mounting structures. DB425A uses a taller side outline, approximately 20.25mm female and 20.50mm male at the indicated envelope, with 4.00mm tail reference. DB425B, DB425C and MP425D show 18.30mm female and 18.50mm male envelope references and 3.20mm tails. Their PCB layouts use Ø1.00mm contact holes with a staggered two-row pattern. DB425A labels the half-pitch offset 1.385mm; the other shown layouts round it to 1.39mm. Use the actual model's drawing for hole positions and shell clearance.
DB468 has a 53.04mm shell width, 47.04mm mounting-hole spacing and 38.38mm interface contact span. Its raised structure includes 31.60mm plan depth, 29.85mm side reference, 26.00mm height reference, 3.20mm tails and UNC4-40 screw threads. The contact grid is 2.77×2.84mm. These references belong to the raised DB468 structure and do not apply to the lower right-angle models.
