NN01-003 Equivalent & Substitute Parts

Part Overview

The NN01-003 is a dual-band chip RF antenna manufactured by Ignion, designed for 802.11a/b/g/n WLAN applications. Operating across 2.4GHz–2.5GHz and 4.9GHz–5.875GHz frequency bands, this surface-mount component delivers 3.9dBi and 9dBi gain across its respective bands. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NN01-003 is determined by the following parameters:

• Antenna Type: Must be chip-based RF antenna
• Mounting Type: Must be surface mount with solder termination
• Frequency Coverage: Must encompass or exceed the 2.4GHz–2.5GHz and 4.9GHz–5.875GHz bands required for 802.11a/b/g/n WLAN operation
• Physical Constraints: Height and form factor must be compatible with existing PCB layouts
• Compliance: RoHS status and MSL rating must meet or exceed the original specification

The NN02-224 qualifies as a substitute based on its ultra-wideband frequency coverage (824MHz–5.875GHz), which fully encompasses the required WLAN bands, combined with compatible surface-mount solder termination and equivalent MSL rating.

Engineering Selection Recommendations

The NN02-224 is the manufacturer-recommended substitute for the obsolete NN01-003. Selection of this alternative is supported by the following factors:

• Frequency Coverage: The NN02-224 operates across 824MHz–5.875GHz, providing complete coverage of the 2.4GHz and 5GHz WLAN bands required by the original design.
• Product Status: The NN02-224 is active and in production, ensuring long-term availability and supply chain continuity.
• Compliance: Both components maintain equivalent MSL ratings (3, 168 Hours) and RoHS compliance status, meeting environmental and handling requirements.
• Physical Integration: The increased height (2.40mm vs. 0.90mm) must be verified against PCB layout constraints and available vertical clearance in the target application.
• Performance Trade-offs: The NN02-224 exhibits lower gain (1.9dBi vs. 3.9dBi/9dBi) and higher VSWR (3 vs. 2), which may require RF circuit tuning or impedance matching adjustments to maintain system performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the NN02-224 directly replace the NN01-003 without PCB modifications?

A: Physical compatibility depends on available vertical clearance. The NN02-224 is 2.40mm tall compared to the NN01-003 at 0.90mm. PCB layout review is required to confirm fit within the allocated component height envelope.

Q: What are the key performance differences between these parts?

A: The NN01-003 provides higher gain (3.9dBi and 9dBi) and lower VSWR (2) optimized for dual-band WLAN operation. The NN02-224 trades band-specific optimization for ultra-wideband coverage, resulting in lower gain (1.9dBi) and higher VSWR (3). RF circuit performance must be re-evaluated with the substitute component.

Q: Are both components RoHS compliant?

A: Yes. The NN01-003 is RoHS Compliant, and the NN02-224 is ROHS3 Compliant. Both meet current environmental standards.

Q: What is the moisture sensitivity level for these components?

A: Both the NN01-003 and NN02-224 carry MSL rating 3 (168 Hours), requiring equivalent handling and storage protocols.

Q: Does the NN02-224 support all WLAN standards required by the original design?

A: Yes. The NN02-224 frequency range (824MHz–5.875GHz) encompasses the 2.4GHz–2.5GHz and 4.9GHz–5.875GHz bands required for 802.11a/b/g/n operation.

Q: What packaging options are available for the NN02-224?

A: The NN02-224 is supplied in Cut Tape (CT) and Digi-Reel packaging formats.
