Procurement Notes

Verify the specific suffix designation during procurement, as variants such as H5012NLT may exist with different packaging configurations like cut tape or reel. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability for this component can fluctuate. Ensure the selected part matches the required NonPoE specification for the target application circuit design.

Selection Notes

Select the H5012NL when a dual-port solution is required for 1000Base-T interfaces without PoE power delivery. Compare physical dimensions against board space constraints, noting its SMD form factor. Evaluate thermal performance requirements against the specified operating temperature range. Consider alternative single-port models if channel count does not match system topology needs.
