Product Description

We regret to inform you that MC723 won't be supplied from September 1st 2025 onwards. A raw material discontinuation and the limited volumes cannot justify spending resources to continue supplying this.

Some close alternatives that you might want to consider are ABP 2035SCR, next to 2025D (lower modulus, successful in lid attach) and or QMI 536HT (~1 W/m-K) depending on your application description and test requirements.
