AI Summary	L79L12ACUTR by STMicroelectronics: Linear Voltage Regulator IC Negative Fixed 1 Output 100mA SOT-89-3.	The NJM79L12UA offers a drop-in SOT-89 footprint with identical pin configuration and improved ripple rejection performance. While it operates down to -40°C, its maximum junction temperature rating of 85°C is lower than the 125°C rating of the L79L12ACUTR. Same SOT-89 surface-mount footprint and drop-in pin assignment (Pin 1 GND, Pin 2 VIN, Pin 3 VOUT) Higher power supply rejection ratio (64 dB vs 42 dB) Wider low-temperature operating capability (-40°C vs 0°C) Lower maximum operating temperature rating (85°C vs 125°C)	The TS79L12CY is a direct physical drop-in alternative in the SOT-89 package with identical pinout and -12V 100mA output capabilities. It offers an extended lower temperature bound of -20°C, though its upper operating temperature is rated to 85°C compared to 125°C for the original part. Same SOT-89 surface-mount footprint and drop-in pin assignment (Pin 1 GND, Pin 2 VIN, Pin 3 VOUT) Wider low-temperature operating capability (-20°C vs 0°C) Lower maximum operating temperature rating (85°C vs 125°C)

You searched one part. Parter watches your whole BOM.

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.
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.
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.
