Substitute Part Grouping Explanation

Substitution of the AH104F2450S1-T is determined by alignment across the following critical parameters:

Frequency Compatibility: The substitute part must operate within the 2.4GHz to 2.5GHz band to maintain RF performance in Bluetooth, WLAN, and Zigbee™ applications.

Antenna Type & Mounting: Both the main part and substitute must be chip-type antennas with surface mount configuration to ensure mechanical and electrical compatibility with existing PCB layouts.

Termination Method: Solder termination is required for direct replacement without assembly process modification.

Physical Dimensions: Maximum height of 0.039" (1.00mm) ensures compatibility with space-constrained applications and existing enclosure designs.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are mandatory for current production and supply chain requirements.

RF Standards Support: Compatibility with 802.15.4, Bluetooth, and WiFi standards ensures functional equivalence across target applications.

The TSA6NA4L2G45NS0S1T meets all substitution criteria and is classified as an active product, providing long-term availability and design continuity.

Engineering Selection Recommendations

The TSA6NA4L2G45NS0S1T is the designated substitute for the AH104F2450S1-T based on the following engineering criteria:

Product Status Alignment: The substitute part carries an Active product status, ensuring continued availability and manufacturing support. The main part's "Not For New Designs" designation necessitates transition to an active alternative for ongoing production and supply chain stability.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements without modification to manufacturing or assembly processes.

Frequency Band Compatibility: The substitute operates within the identical 2.4GHz to 2.5GHz frequency range, supporting all three RF standards (802.15.4, Bluetooth, WiFi) required by the original design.

Physical and Electrical Interface: Matching surface mount configuration, solder termination, and maximum height of 1.00mm ensure direct PCB layout compatibility without redesign.

Moisture Sensitivity: Both parts share MSL rating 1 (Unlimited), eliminating moisture-related handling and storage requirement changes.

The TSA6NA4L2G45NS0S1T provides functional and mechanical equivalence for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the TSA6NA4L2G45NS0S1T be used as a direct replacement for the AH104F2450S1-T without PCB modification?

A: Yes. Both parts are chip-type surface mount antennas with identical maximum height (1.00mm), solder termination, and mounting footprint compatibility. No PCB layout changes are required.

Q: What is the difference between the 2.4GHz and 2.45GHz center frequencies listed for each part?

A: Both parts operate across the full 2.4GHz to 2.5GHz frequency range. The center frequency designation indicates the optimized operating point within this band. The substitute's 2.45GHz center frequency remains within the specified range and supports all three RF standards (802.15.4, Bluetooth, WiFi) without functional impact.

Q: Are there compliance or certification differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL rating 1 (Unlimited). No compliance-related changes to assembly, storage, or handling procedures are required.

Q: Why is the gain specification not provided for the TSA6NA4L2G45NS0S1T?

A: The substitute part datasheet does not include gain specification in the provided parameters. Both parts operate within the 2.4GHz to 2.5GHz band and support identical RF standards, ensuring functional compatibility for Bluetooth, WLAN, and Zigbee™ applications.

Q: What is the packaging format for both parts?

A: Both the AH104F2450S1-T and TSA6NA4L2G45NS0S1T are supplied in Tape & Reel (TR) packaging, maintaining consistency with existing procurement and assembly processes.

Q: Is the TSA6NA4L2G45NS0S1T suitable for new design implementations?

A: Yes. The substitute part carries Active product status, making it appropriate for both existing design support and new product development. The main part's "Not For New Designs" status is the primary reason for substitution.
