Substitute Part Grouping Explanation

Substitution of the NN01-055 is based on the following criteria derived from the provided parameters:

Allowed Substitution Parameters:

• Antenna type: Chip
• Mounting type: Surface Mount
• Termination method: Solder
• Frequency coverage: Must encompass or extend the 78MHz – 108MHz range
• RoHS compliance: Must maintain or exceed current compliance level
• MSL rating: Must be compatible with 3 (168 Hours) or better

The NN01-055 is listed with one manufacturer-recommended substitute: NN03-310. This substitute is provided by the same manufacturer (Ignion) and maintains core mechanical and electrical compatibility parameters while extending frequency coverage and application scope.

Engineering Selection Recommendations

The NN03-310 is the manufacturer-recommended substitute for the NN01-055. Selection should be based on the following engineering factors:

Product Status: The NN03-310 maintains active product status, ensuring ongoing availability and manufacturer support, whereas the NN01-055 is obsolete.

Compliance: The NN03-310 exceeds the compliance requirements of the NN01-055, meeting ROHS3 Compliant standards compared to RoHS Compliant. Both components maintain identical MSL ratings of 3 (168 Hours).

Physical Compatibility: Both components are surface mount chip antennas with solder termination. The NN03-310 features a reduced maximum height of 0.039" (1.00mm) compared to 0.063" (1.60mm), which may provide layout advantages in space-constrained applications.

Frequency Coverage: The NN03-310 provides extended frequency coverage from 698MHz to 3.8GHz, encompassing the original 78MHz – 108MHz range and supporting additional frequency bands for 2G/3G/4G/5G, Bluetooth, GNSS, ISM, LTE, UWB, and Wi-Fi applications.

Frequently Asked Questions (FAQ)

Q: Can the NN03-310 directly replace the NN01-055 in existing designs?

A: The NN03-310 is the manufacturer-recommended substitute and maintains mechanical compatibility as a surface mount chip antenna with solder termination. However, the extended frequency range and multiband capability of the NN03-310 require verification that the application circuit and impedance matching networks are compatible with the substitute component's electrical characteristics.

Q: What is the primary difference between these two components?

A: The NN01-055 is a single-band VHF antenna (78MHz – 108MHz), while the NN03-310 is a multiband antenna covering 698MHz – 3.8GHz across 12 frequency bands. The NN03-310 also features a lower profile (0.039" vs. 0.063") and active product status.

Q: Are there packaging differences between the NN01-055 and NN03-310?

A: The NN01-055 packaging is listed as standard, while the NN03-310 is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes.

Q: Do both components meet the same moisture sensitivity requirements?

A: Yes, both the NN01-055 and NN03-310 carry an MSL rating of 3 (168 Hours), indicating identical moisture sensitivity handling requirements.

Q: Is the NN03-310 suitable for VHF-only applications?

A: The NN03-310 is designed as a multiband antenna and will operate across its full 698MHz – 3.8GHz range. For VHF-only applications, circuit design and impedance matching must be verified to ensure proper performance at the intended frequency.
