Datasheet Review

flux

I’ll inspect the part metadata and existing symbol/footprint, find the official datasheet if needed, update the Datasheet property, then compare pins and footprint details against the datasheet.

flux

I found and set the official TRACO datasheet URL, and I’m documenting the datasheet comparison plus the footprint issue now.

Completed the review and set the part’s Datasheet URL to the official TRACO Power THN 15WIR PDF. Full findings are in Part Datasheet Review - THN 15-2411WIR.
Open items:
  • Critical mismatch: footprint pads are all stacked at (0,0) with near-zero size, so the footprint is not usable as-is.
  • Pin numbers/functions match the datasheet, but pin descriptions and electrical pin types are not populated.
  • Library index shows Other for part type/manufacturer despite correct project properties.
Suggested next steps:
  1. Rebuild the footprint from the datasheet 6-pin 1" × 1" through-hole module coordinates.
  2. Add proper pin descriptions and electrical pin types.
  3. Add package outline/courtyard and practical plated-through pad/drill sizing for 1.0 mm pins.

Part Datasheet Review - THN 15-2411WIR
Date: 2026-07-12
Scope
Reviewed available part/project information, searched for and set the official datasheet URL, then cross-checked schematic pin terminals, footprint pads, and pin descriptions against the TRACO Power THN 15WIR datasheet.

Datasheet Source
Official datasheet URL set on the part:
The official TRACO PDF URL was found via web search/distributor datasheet links. The automated PDF scrape of the official URL returned a fetch error/403 in one path, but the datasheet content was successfully extracted through Flux datasheet search using the project datasheet property and corroborated by a Mouser-hosted copy of the TRACO datasheet.

Symbol / Pin Description Findings
  • Pin count is correct: 6 schematic terminals.
  • Pin numbers match the datasheet single-output pinout.
  • Pin names/designators match semantically.
  • Pin descriptions are not populated; the terminal components only expose pin number and unspecified pin type.
  • Pin electrical types are all Unspecified; more useful types would be Power In for pins 1/2 input, Power Out for pins 3/5 output, and Input or Signal for Trim and Remote On/Off.
  • No schematic nets are present, which is acceptable for a standalone part definition but means there is no application wiring to validate.
Datasheet Mechanical / Footprint Reference
Datasheet mechanical view is bottom view. Using pin 1 as (0, 0), with X positive to the right and Y positive downward in the datasheet bottom view:

Footprint Findings
  • The footprint is not valid for manufacturing or layout use in its current state.
  • All six pads are stacked at the origin instead of the datasheet bottom-view pin coordinates.
  • Pad size is effectively zero (0.0016 mm), not suitable for a 1.0 mm through-hole pin.
  • No explicit pad/drill rules are present.
  • The package outline/courtyard for the 25.4 mm x 25.4 mm module is not represented in the inspected layout nodes.
Mismatches / Issues to Flag
  1. Critical footprint mismatch: all pads are stacked at (0,0) and are near-zero size. This must be fixed before the part can be used on a PCB.
  2. Missing/weak pin metadata: pin numbers and functions match, but pin descriptions and electrical pin types are not set.
  3. Library indexing inconsistency: library search reports part_type: Other and manufacturer: Other, although project properties have Part Type: Power Supplies and Manufacturer Name: Traco Power.
  4. Datasheet exact pad/drill dimensions were not found in extracted text. Use the 1.0 mm pin diameter and standard through-hole manufacturability rules to choose a suitable plated drill/pad, or obtain the manufacturer recommended land pattern if available.
  • Rebuild the footprint with six through-hole pads at the datasheet coordinates.
  • Add a 25.4 mm x 25.4 mm component outline/courtyard and maintain bottom-view/top-view orientation carefully.
  • Choose a practical plated-through drill larger than the 1.0 mm pin diameter, with an annular pad sized for the target fabricator, unless an official recommended drill/pad is obtained.
  • Populate pin descriptions and electrical pin types:
    • Pin 1 +Vin/Vcc: Power In
    • Pin 2 -Vin/GND: Power In or Ground/Power return, depending Flux convention
    • Pin 3 +Vout: Power Out
    • Pin 4 Trim: Input/Signal
    • Pin 5 -Vout: Power Out return
    • Pin 6 Remote On/Off: Input/Signal
  • Consider updating library index fields so manufacturer and part type appear as Traco Power and Power Supply rather than Other.
Internal Escalation
A part quality report was filed because the footprint appears unusable as-is.
