  • Termination style: CBR/CBRP “Condensed Right-Angle PCB terminations” [datasheet]
Package dimensions and PCB pattern (CBR/CBRP; 37 contacts)
  • Dimensional table (CBR series; MDB-37SCBR): A 1.488 in (37.79 mm), B 1.265 in (32.13 mm), C 1.075 in (27.30 mm), D 0.218 in (5.54 mm), E 0.218 in (5.54 mm), F 0.520 in (13.21 mm), G 0.250 in (6.35 mm), H 0.130 in (3.30 mm) [catalog]
  • PCB termination arrangement: “All termination configurations .100 in (2.54 mm) x .100 in (2.54 mm) grid pattern, offset .050 in (1.27 mm).” Contact spacing along a row is 0.050 in (1.27 mm) [catalog]
  • Hardware/jackpost mounting hole guidance (when present per suffix option):
    • Sizes 9–51: 0.091 in (2.31 mm) hole for “B – no hardware standard”; 0.125 in (3.18 mm) hole for “A – no hardware” [catalog]
    • Size 100 variants have larger values; not applicable here [catalog]
  • Pin-numbering note: PCB termination arrangement drawings are “Viewed from bottom of connector (PCB solder side). Identification number shown for plug connector; use reverse order for socket connector.” [catalog]
Special features
  • Metal shell provides shielding [datasheet]
  • ITT Cannon Micro-D uses twist pin/solid-tube contact technology in the series (not always repeated in each abbreviated part sheet, but covered in series materials) [series materials]
  1. Cross-check of symbol and footprint vs datasheet
  • Pin count
    • Datasheet: 37 contacts for the -37S- arrangement.
    • Schematic symbol: 37 terminals present; matches.
    • Footprint: 37 signal pads present; matches.
  • Shield/shell representation and mounting hardware
    • Datasheet: Metal shell for shielding; the “P” option indicates jackpost locking hardware. Jackposts are mechanical features with associated panel or PCB mounting holes; they are not plated electrical contacts intended to be tied into the netlist.
    • Schematic symbol currently uses two separate electrical terminals both named SHIELD (Pin Numbers SH1, SH2). This can cause:
      • Duplicate designator usage in schematic and BOM.
      • Creation of two “electrical nets” for what are likely mechanical holes/jackposts or non-electrical mounting features.
    • Footprint includes two pads labeled SHIELD (two instances). If these are implemented as plated electrical pads, that likely does not match the catalog which shows mechanical holes for jackposts/mounting. They should be non-plated mechanical holes, not pads in the electrical netlist.
    • Actionable flag:
      • Replace the two “SHIELD” electrical terminals in the schematic with mechanical mounting features (no net). If you want a chassis/shell reference, add a single “Shell/Shield” symbol that corresponds to a defined mechanical tie or a dedicated solderable shield lug that actually exists on the chosen variant. Otherwise, omit shield from the electrical netlist.
      • In the footprint, convert “SHIELD” from electrical pads to mechanical/non-plated mounting holes sized per the hardware option. For the “P” jackpost option typically used with CBRP, use the catalog’s hole dimensions applicable to shell sizes 9–51 (commonly 0.125 in for the A-mount or 0.091 in for the B-mount, depending on hardware callout). Confirm the exact hardware callout for “P” in your selected sub-variant before finalizing hole diameter.
  • Pin numbering orientation
    • Datasheet note says PCB diagrams show plug numbering and you must reverse for socket connectors. Because the part is an “S” (socket/receptacle), ensure your pad/symbol numbering follows the socket convention. If your schematic numbering was copied from a plug view, it could be reversed.
    • Recommendation: Verify the left-to-right numbering sequence against the “socket (reversed)” orientation from the catalog drawing for 37 contacts before releasing.
  • Grid/pitch consistency
    • Datasheet: contacts are on a 0.050 in (1.27 mm) pitch with a .100 in x .100 in grid offset by .050 in. If your footprint uses a simple 1.27 mm by 1.27 mm rectangular grid without the .050 in offset pattern, it will not match the CBR/CBRP tails.
    • Recommendation: Confirm your pad lattice matches the .100 x .100 with .050 offset scheme from the catalog for 37 positions.
  • Mounting hole presence and size
    • For CBR/CBRP with jackposts, the footprint should include two appropriately sized mechanical holes positioned per the catalog drawing (not connected to the netlist). If your current footprint only has 37 contact pads and two “shield” pads but no mechanical holes sized per the hardware option, that’s a mismatch.
Would you like me to:
  • Apply the “Datasheet” project property update now using the official ITT Cannon catalog link above?
  • Then, I can fix the symbol/footprint issues by:
    • Removing the two electrical SHIELD terminals from the netlist,
    • Adding non-plated mounting holes per the CBRP jackpost option,
    • Verifying the 37-pin numbering order matches the socket orientation,
    • Ensuring the pad matrix uses the .100 x .100 grid with .050 offset and 0.050 in along-row spacing.
