FFF CompatibilityThe alternative LM317D2TG is in a surface-mount D2PAK-3 package, which is physically incompatible with the source part's through-hole TO-3 metal can footprint.The alternative's surface-mount D2PAK-3 physical form factor and mounting style are entirely different from the source's bulky TO-3 metal can chassis mounting.The alternative LM317D2TG operates over a narrower temperature range of 0°C to +125°C compared to the military/high-reliability range of -55°C to +150°C of the source LM117H.
AI Summary

LM117H by Texas Instruments: Linear Voltage Regulator IC Positive Adjustable 1 Output 1.5A TO-3.

Functional alternative with matching output voltage and current specs, but in a completely different surface-mount footprint and with a narrower temperature range.

  • Modern surface-mount design
  • Same nominal 1.5 A output current capability
  • Same 1.2 V to 37 V adjustable output voltage range
  • Requires board layout/redesign due to surface-mount D2PAK package vs metal can TO-3
  • Narrower operating junction temperature range (0°C to +125°C vs -55°C to +150°C)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
