Procurement Notes

Verify component authenticity as the HEF4027BP,652 is listed as obsolete and no longer manufactured by NXP USA Inc. Ensure substitute components meet original pinout and electrical specifications. Confirm RoHS compliance status for current inventory sources. Validate supplier authorization to prevent counterfeit risks in legacy procurement channels.

Selection Notes

Select this component only if legacy compatibility with existing 16-DIP PCB footprints is required. Consider that the part is obsolete; active alternatives may require schematic redesign or adapter solutions. Evaluate whether modern CMOS equivalents offer improved speed or lower power while maintaining functional parity for the specific application requirements.

Part Context

This device belongs to the HEF4000B series of CMOS logic ICs. It serves as a fundamental building block for sequential logic circuits. The 'BP' suffix indicates a plastic DIP package variant. The '652' code typically denotes tape-and-reel packaging specifications within the NXP product line.

Replacement Considerations

Public confirmed substitutes are not explicitly listed in the provided source material. Verify availability of direct replacements such as the HEF4027BT or equivalent generic 4027B series parts from other manufacturers ensuring identical pin configurations.
