Procurement Notes
Verify the specific lot marking and date code upon receipt to ensure authenticity. Confirm that the dual-marked designation matches the required military or commercial specifications. Request detailed test reports if the application demands strict adherence to original MIL-SPEC parameters. Ensure storage conditions prevent electrostatic discharge damage during handling.
Selection Notes
Select this component when a verified source for the M38510/33702BEA specification is required. Consider the package type compatibility with existing PCB footprints. Evaluate the operating temperature range against environmental constraints. Verify pinout alignment with legacy designs utilizing the standard 54F series architecture.
Part Context
This part belongs to the 54F series, indicating military-grade reliability standards originally. Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find components. The dual marking confirms traceability to the original manufacturer's specifications. This ensures functional equivalence to the initial design requirements.
Replacement Considerations
Direct substitutes include JD54F139BEA from Teledyne e2v. Verify pin compatibility and electrical characteristics before integration. Cross-reference datasheets to confirm identical logic truth tables and timing parameters.
