What is M38510/07002BCA?
The M38510/07002BCA is a 54S03 series Quadruple 2-Input Positive NAND Gate, a standard logic device from the 54S Schottky TTL family. It integrates four independent NAND gates with open-collector outputs, each with two inputs, in a single package. This part carries JAN/883 qualification, meaning it is screened to military reliability standards for defense and aerospace applications.
Lifecycle and sourcing posture
For the spare-parts storeroom keeper, this means the part remains available through the standard supply chain without imminent EOL risk.
Package and storage considerations
not Tape & Reel. No moisture sensitivity level (MSL) is declared for this hermetic ceramic package, so dry-storage precautions typical for plastic packages do not apply. Store the tubes or trays in a standard ESD-safe environment — no bake-out needed before reflow. The ceramic body and lead finish are compatible with high-reliability soldering processes used in military and avionics assembly.
