Key Parameters

Substitute Part Grouping Explanation

Substitution of the NN01-004 is determined by the following critical parameters:

Frequency Coverage: The substitute must operate across both the 2.4GHz band (2.4GHz ~ 2.5GHz) and 5GHz band (4.9GHz ~ 5.875GHz) to maintain dual-band WLAN functionality.

Antenna Type: Chip-type antenna configuration is required for form factor and integration compatibility.

Mounting Configuration: Surface-mount solder termination is mandatory for PCB assembly compatibility.

RF Standard: WiFi (802.11a/b/g/n) compliance is required for application compatibility.

Electrical Performance: Gain values and VSWR characteristics must fall within acceptable ranges for the target application's link budget and impedance matching requirements.

The ANT5320LL04R2455A from Pulse Electronics meets these substitution criteria through equivalent dual-band coverage, chip antenna architecture, surface-mount solder termination, and WiFi standard compliance.

Engineering Selection Recommendations

The ANT5320LL04R2455A is qualified as a direct substitute for the NN01-004 based on the following engineering criteria:

Frequency Coverage Alignment: Both parts provide dual-band WiFi antenna functionality with overlapping frequency ranges. The ANT5320LL04R2455A covers 2.375GHz ~ 2.525GHz and 5.05GHz ~ 5.95GHz, which encompasses the NN01-004's specified bands of 2.4GHz ~ 2.5GHz and 4.9GHz ~ 5.875GHz.

Form Factor Compatibility: The ANT5320LL04R2455A features a reduced height of 0.055" (1.40mm) compared to the NN01-004's 0.079" (2.00mm), providing improved PCB real estate utilization while maintaining surface-mount solder termination compatibility.

Compliance Status: The ANT5320LL04R2455A holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The NN01-004's obsolete status necessitates transition to an active alternative.

Electrical Performance: Gain characteristics are comparable across both bands, with the ANT5320LL04R2455A providing 2.09dBi at 2.4GHz and 4.32dBi at 5GHz, supporting equivalent link budget performance for 802.11a/b/g/n applications.

Frequently Asked Questions (FAQ)

Q: Can the ANT5320LL04R2455A directly replace the NN01-004 in existing designs?

A: Yes. Both components are chip-type antennas with dual-band WiFi coverage, surface-mount solder termination, and compatible frequency ranges. The ANT5320LL04R2455A's reduced height may provide layout advantages without requiring design modification.

Q: What are the key differences in electrical performance?

A: The ANT5320LL04R2455A provides slightly higher gain at 2.4GHz (2.09dBi vs. 1.5dBi) and marginally lower gain at 5GHz (4.32dBi vs. 4.7dBi). Return loss is specified for the ANT5320LL04R2455A at -6.5dB, while VSWR is specified for the NN01-004 at 2. Both configurations support standard WiFi link budget requirements.

Q: Are there packaging differences between these parts?

A: The NN01-004 is supplied in Cut Tape (CT) packaging, while the ANT5320LL04R2455A is supplied in Tape & Reel (TR) packaging. Both are suitable for automated assembly processes; packaging selection depends on production volume and handling requirements.

Q: What is the height difference impact on PCB layout?

A: The ANT5320LL04R2455A is 0.024" (0.60mm) shorter than the NN01-004. This reduced profile may allow for improved component density or clearance in space-constrained applications without affecting electrical performance.

Q: Are both parts RoHS compliant?

A: Yes. The NN01-004 is RoHS Compliant, and the ANT5320LL04R2455A is ROHS3 Compliant, meeting current environmental and regulatory requirements.

Q: Why is the NN01-004 classified as obsolete?

A: Manufacturer discontinuation of the NN01-004 necessitates transition to active alternatives. The ANT5320LL04R2455A provides equivalent functionality with confirmed long-term availability.
