Antennas RF Procurement Notes

This component is officially obsolete and no longer in production, with discontinuation announced on March 14, 2017. Procurement should focus on verified replacement part numbers rather than original stock. Verify that substitute components meet identical electrical specifications, particularly frequency range and gain requirements, to ensure system compatibility. Confirm package dimensions and mounting style match existing design constraints before integration.

Antennas RF Selection Notes

Select this component only if legacy design compatibility is required or if specific historical performance data is mandated. Due to its obsolete status, primary consideration must be given to active replacement parts. Ensure any alternative solution supports the same L1 GPS frequency band and offers comparable gain characteristics. Verify that the replacement maintains the same surface mount footprint and height restrictions to avoid PCB redesign.

Antennas RF Part Context

The ACA-104-T belongs to the ACA series of RF antennas from Abracon LLC. This series includes various chip antennas designed for different wireless applications such as cellular, Bluetooth, and WCDMA. The ACA-104-T is specifically tuned for GPS navigation frequencies. Other models in the family may support broader frequency ranges or different mounting configurations, but this specific part number is dedicated to single-band GPS operations.

Antennas RF Replacement Considerations

The AH316M157501-T from Taiyo Yuden is documented as a similar replacement part. Verify that the substitute matches the 1.575GHz center frequency and surface mount package type. Check if the replacement offers equivalent gain and VSWR performance to maintain signal integrity in GPS applications.
