AI Summary	ATM601-CuH-S by AOTE: 7V 50mA 5V 1.33V 4.5V~5.5V DC S0P-5 Logic Output Optoisolators RoHS.	The HCPL-M611-500E is a higher-CMR variant in the same Broadcom 5-SO logic optocoupler series, offering enhanced noise immunity of 10 kV/µs minimum. It is physically and electrically drop-in compatible with an open-collector output and 10 MBd speed. Its operating temperature ceiling is -40°C to +85°C, compared to +125°C for the ATM601-CuH-S. Pin-compatible drop-in replacement in 5-SO / SOP-5 package Higher common-mode transient immunity rating (10 kV/µs min vs 5 kV/µs min) Matches 10 MBd speed, open-collector logic gate output, and 3750 Vrms isolation rating Narrower operating temperature range (-40°C to +85°C vs -40°C to +125°C)	The ACPL-M61L-000E is a 10 MBd logic optocoupler in a matching 5-SO package featuring a totem-pole (push-pull) output stage and high 20 kV/µs CMR. Because the output is active push-pull rather than open collector, any existing external pull-up resistor on the board should be reviewed or removed. Additionally, its maximum operating temperature is +105°C versus +125°C for the ATM601-CuH-S. Pin-compatible 5-SO package footprint Superior common-mode transient immunity (20 kV/µs min) Wider operating supply voltage range (2.7 V to 5.5 V) Totem-pole / push-pull output driver stage differs from open collector (requires circuit review if pull-up resistor is present) Narrower operating temperature range (-40°C to +105°C vs -40°C to +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.
