Key Parameters

Substitute Part Grouping Explanation

Substitution of the NN01-104 is based on the following critical parameters that must align across equivalent parts:

Mandatory Matching Parameters:

• Frequency Range: 2.4 GHz ~ 2.5 GHz
• Antenna Type: Chip
• Mounting Type: Surface Mount
• Termination: Solder
• RF Family/Standard: Bluetooth compatibility

Allowable Variation Parameters:

• Gain: Substitute may vary within practical RF performance limits (1.1 dBi to 1.3 dBi)
• Height: Substitute may exceed original height if board space permits (0.90 mm to 2.00 mm)
• VSWR: Substitute specifications may differ if return loss is specified
• Packaging: Substitutes may use different packaging formats (Cut Tape to Tape & Reel)
• Moisture Sensitivity Level: Substitute may have lower MSL rating (more favorable)
• Product Status: Active status substitutes are preferred for obsolete parts

The 2450AT43B0100001E from Johanson Technology Inc. meets all mandatory matching parameters and represents a direct functional equivalent.

Engineering Selection Recommendations

Primary Substitute: 2450AT43B0100001E (Johanson Technology Inc.)

The 2450AT43B0100001E is the direct equivalent for the obsolete NN01-104. Selection of this substitute is supported by the following factors:

Compliance & Regulatory:

• Both parts share identical ECCN (EAR99) and HTSUS (8517.71.0000) classifications
• Substitute is RoHS3 Compliant and REACH Unaffected, providing superior regulatory alignment

Product Status:

• Substitute maintains Active product status, ensuring long-term availability and supply chain continuity
• Original part is Obsolete, making substitution necessary for new designs and ongoing production

RF Performance:

• Identical frequency range (2.4 GHz ~ 2.5 GHz) and frequency group (UHF)
• Gain increase from 1.1 dBi to 1.3 dBi represents improved antenna efficiency
• Return loss specification (-9.5 dB) on substitute provides quantified impedance matching performance

Mechanical Compatibility:

• Both parts are chip-type, surface mount antennas with solder termination
• Height increase from 0.90 mm to 2.00 mm requires board layout verification but does not preclude substitution
• Packaging change from Cut Tape to Tape & Reel accommodates higher volume procurement

Environmental Handling:

• Substitute MSL rating of 1 (Unlimited) is more favorable than original MSL 3 (168 Hours), reducing moisture-related handling constraints

Frequently Asked Questions (FAQ)

Q: Can the 2450AT43B0100001E directly replace the NN01-104 without circuit modifications?

A: The 2450AT43B0100001E operates within the identical frequency range (2.4 GHz ~ 2.5 GHz) and maintains the same antenna type, mounting method, and termination. Both parts are designed for Bluetooth and WLAN applications. No circuit modifications are required. Board layout must accommodate the increased height (2.00 mm vs. 0.90 mm).

Q: What is the significance of the gain difference (1.1 dBi vs. 1.3 dBi)?

A: The 0.2 dBi gain increase in the substitute represents improved antenna efficiency. This results in enhanced signal transmission and reception performance. The increase is within typical performance variation for chip antennas in this frequency band and is beneficial for system performance.

Q: Why does the substitute specify Return Loss (-9.5 dB) while the original specifies VSWR (2)?

A: Both parameters characterize impedance matching quality. Return Loss of -9.5 dB is equivalent to a VSWR of approximately 1.9, which is comparable to the original VSWR of 2. The substitute uses the more precise Return Loss specification.

Q: Does the packaging change from Cut Tape to Tape & Reel affect component compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. The change from Cut Tape (CT) to Tape & Reel (TR) is a procurement and handling consideration. Tape & Reel packaging is standard for higher volume applications and provides improved automation compatibility.

Q: Is the increased height (2.00 mm vs. 0.90 mm) a concern for board integration?

A: Height increase must be evaluated against available board space and clearance requirements. The substitute is 1.1 mm taller. If the original design has height constraints, board layout review is necessary. In most applications with standard PCB clearances, this height difference does not present integration issues.

Q: What are the advantages of the substitute's MSL rating of 1 compared to the original MSL 3?

A: MSL 1 (Unlimited) indicates the substitute has superior moisture resistance compared to MSL 3 (168 Hours). This reduces handling and storage constraints, allowing extended shelf life without desiccant packaging and simplifying supply chain logistics.

Q: Are both parts suitable for Zigbee™ applications?

A: The original NN01-104 explicitly lists Zigbee™ in its applications. The substitute 2450AT43B0100001E lists Bluetooth, Wi-Fi, and WLAN applications. Both operate in the 2.4 GHz ~ 2.5 GHz band used by Zigbee™. The substitute is compatible with Zigbee™ systems based on frequency alignment, though Zigbee™ is not explicitly listed in its application specification.

Q: What regulatory certifications apply to both parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8517.71.0000) classifications. The substitute provides additional compliance documentation: RoHS3 Compliant and REACH Unaffected status, offering enhanced regulatory alignment for international markets.
