NN01-102 Equivalent & Substitute Parts Reference

Part Overview

The NN01-102 is a compact chip RF antenna manufactured by Ignion, designed for 2.45GHz multi-protocol wireless applications including Bluetooth, WLAN, and Zigbee™. Operating across the 2.4GHz to 2.5GHz frequency band, this surface mount antenna delivers 1.7dBi gain with a VSWR of 2 and solder termination. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support, legacy system maintenance, and component sourcing continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NN01-102 is determined by strict alignment of the following electrical and mechanical parameters:

• Frequency Coverage: Center frequency of 2.45GHz with operating range 2.4GHz to 2.5GHz
• Antenna Type: Chip configuration only
• Mounting Method: Surface mount with solder termination
• RF Standards Support: Bluetooth, WLAN, and Zigbee™ protocol compatibility
• Frequency Group: UHF band (2GHz to 3GHz)
• VSWR Performance: Maximum VSWR of 2
• Physical Form Factor: Compact surface mount package suitable for PCB integration

The substitute part 7488940245 (Würth Elektronik WE-MCA series) meets all critical substitution criteria within the allowed parameter tolerance.

Parameter Comparison

Engineering Selection Recommendations

The NN01-102 is obsolete and no longer in active production. The substitute part 7488940245 from Würth Elektronik is actively manufactured and maintains full compliance with current RoHS3 standards, providing superior regulatory alignment compared to the original RoHS Compliant designation.

Both parts share identical frequency range coverage (2.4GHz to 2.5GHz), VSWR performance (2), and solder termination methodology. The substitute exhibits improved moisture sensitivity (MSL 1 versus MSL 3), indicating superior handling characteristics during storage and assembly. The 0.3dBi gain differential (1.7dBi to 2dBi) and reduced height profile (2.00mm to 1.20mm) of the substitute represent performance enhancements suitable for space-constrained applications.

Selection of the substitute part is supported by active product status, REACH compliance documentation, and established supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 7488940245 directly replace the NN01-102 in existing designs?

A: Yes. Both parts operate identically across the 2.4GHz to 2.5GHz frequency band with matching VSWR of 2 and solder termination. The substitute's improved gain (2dBi versus 1.7dBi) and reduced height (1.20mm versus 2.00mm) are compatible with standard PCB layouts designed for the original part.

Q: What is the significance of the MSL rating difference?

A: The NN01-102 carries MSL 3 (168-hour moisture sensitivity limit), while the 7488940245 carries MSL 1 (unlimited). MSL 1 indicates superior moisture resistance and eliminates time-based storage constraints, reducing handling complexity during manufacturing and inventory management.

Q: Are there packaging differences between these parts?

A: Yes. The NN01-102 is supplied in Cut Tape (CT) packaging, while the 7488940245 is supplied in Tape & Reel (TR) packaging. Tape & Reel format is standard for high-volume production environments and offers improved automation compatibility.

Q: Do both parts support the same wireless protocols?

A: Both parts support Bluetooth and WiFi standards across the 2.4GHz to 2.5GHz band. The NN01-102 explicitly supports 802.15.4 and Zigbee™, while the 7488940245 supports Bluetooth, Cellular, and WiFi. Protocol support is determined by system-level implementation rather than antenna capability.

Q: What compliance certifications apply to the substitute part?

A: The 7488940245 is ROHS3 Compliant and REACH Affected, meeting current European regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8517.71.0000) classifications.
