Quantifying Initial Unit Cost Premiums in Split Hardware Sourcing Allocations
Split hardware sourcing increases initial unit costs by 12 to 38 percent through volume tier loss, duplicate tooling, and secondary line qualification.
Component Second Sourcing
Meaning
Procurement strategy establishes alternative qualified parts to prevent production halts during supply chain disruptions. Implementing component second sourcing requires extensive testing to ensure that the alternative part matches the pinout and electrical behavior of the primary component. The boundary of this practice is reached when a substitute part alters the radio frequency performance or requires a board layout redesign.
Validation Sequence
Engineers first measure the electrical characteristics of the candidate part against the primary device on a test bench. Next, the alternative component undergoes reflow assembly on several prototype boards to evaluate soldering yield. Thermal testing then verifies that the power dissipation remains within the acceptable system budget.
This step-by-step approach prevents field failures after full production begins.
Supply Security
Sourcing alternative components can trigger the need for a permissive change filing if the transmitter RF path is altered. The engineering team must review the regulatory constraints to ensure compliance. If the new part is identical, no additional filing is needed.
