The phrase "alter component" is correct and usable in written English.
It can be used in contexts where you are discussing modifications or changes to a specific part of a system, device, or structure.
Example: "To improve the performance of the machine, we need to alter the component responsible for energy efficiency."
Alternatives: "modify part" or "change element".
The WSJ is reporting that HTC is now working with Qualcomm to alter components to prevent another possible lawsuit.
Similarly, for disaster risk governance systems, we can expect disasters to alter components of the system, at least temporarily – whether perturbations are low-intensity but frequent or singular, high-intensity events.
A wave of new research has incorporated a multispecies community context, showing that additional ecological interactions can alter components of host and parasite fitness, as well as interaction specificity and virulence.
Indeed, the effects of recent trauma, thoracic surgery, or prior radiation therapy alter components of the mediastinal silhouette and compromise the utility of the VPW [ 18, 19].
These viruses may alter components of PML-NBs, regulate expression and localization of PML protein, and even disrupt PML-NB structure (recent review in [ 131]).
Minimization of cement strain, especially at the crucial proximal and distal areas of the stem, by altering component design may be able to reduce cement prosthesis debonding and improve clinical results.
Overexpression of Wnt4 may interrupt such a relationship, by either changing the cell membrane structure of chondrocytes or altering components of the ECM.
Acidosis and low oxygen significantly altered components of the redox system.
Emerging evidence suggests that altered components and post-translational modifications (PTMs) of proteins in the ECM may both initiate and drive disease progression (Leeming et al., 2011a).
We demonstrate that PGE2 modifies canonical Wnt signalling in NE-4C stem cells by altering components of cell motility such as final distance travelled, path length travelled, average speed of migration, as well as cell splitting behaviour.
