Substitute Part Grouping Explanation

Substitution eligibility for the 455-0012 is determined by strict alignment across the following core parameters:

Frequency Requirement: 915MHz operation is mandatory for RF compatibility within the target application band.

Protocol Support: Both Bluetooth v4.2 and LoRaWAN support must be present to maintain dual-connectivity functionality.

Environmental Rating: IP65 protection classification ensures equivalent environmental sealing and durability.

Manufacturer Consistency: Laird Connectivity Inc. maintains design and performance standards across the Sentrius™ series.

Base Product Compatibility: Parts sharing the 455-0 base product number are engineered within the same product family architecture.

The substitute part 455-00070 satisfies all substitution criteria through identical frequency, protocol support, environmental rating, and manufacturer origin within the same product series.
