Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 455-0004 is determined by the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Laird Connectivity Inc.
• Series: Sentrius™
• Function: Temperature and humidity sensor
• Protocols: Bluetooth v4.2 and LoRaWAN support
• Regulatory Compliance: RoHS Compliant status
• Base Product Number: 455-0 family

The substitute part 455-0002 meets all primary substitution criteria. Both parts share the same manufacturer, series designation, sensor function, dual-protocol support, and regulatory compliance framework. The primary distinction lies in frequency band specification: the 455-0004 operates across dual bands (863MHz–870MHz and 902MHz–928MHz), while the 455-0002 operates at a single frequency (868MHz). The 868MHz frequency falls within the European ISM band and is compatible with LoRaWAN deployments in EU regions.

Parameter Comparison

Engineering Selection Recommendations

For the 455-0002 as a substitute for the 455-0004:

The 455-0002 is an active product within the same Sentrius™ series and maintains full protocol and functional equivalence. Both parts are RoHS Compliant and share identical ECCN and HTSUS classifications, ensuring regulatory and compliance alignment.

The primary technical distinction is frequency band coverage. The 455-0004 supports dual-band operation (863MHz–870MHz and 902MHz–928MHz), enabling deployment across both European and North American LoRaWAN networks. The 455-0002 operates at 868MHz, which is the standard European LoRaWAN frequency and is suitable for EU-region deployments.

Selection Criteria:

• Use 455-0002 if: Your application is limited to European LoRaWAN networks or operates exclusively within the 868MHz band.
• Frequency band compatibility: Verify that your network infrastructure and gateway configuration support 868MHz operation before substitution.
• Supply availability: The 455-0002 is currently in active production status with confirmed inventory (1204 Pcs), whereas the 455-0004 is obsolete.

Frequently Asked Questions (FAQ)

Q1: Can the 455-0002 directly replace the 455-0004 in all applications?

A: The 455-0002 is functionally equivalent for temperature and humidity sensing with LoRaWAN and Bluetooth v4.2 connectivity. However, substitution depends on frequency band requirements. If your application requires dual-band operation (863MHz–870MHz and 902MHz–928MHz), the 455-0002's single 868MHz band may not provide full coverage. Verify your network's frequency band support before substitution.

Q2: What is the significance of the frequency difference between these parts?

A: The 455-0004 operates across two frequency bands: the European ISM band (863MHz–870MHz) and the North American ISM band (902MHz–928MHz). The 455-0002 operates at 868MHz, which is the center frequency of the European LoRaWAN band. If your deployment is geographically limited to Europe, the 455-0002 is suitable. For multi-region deployments, the dual-band capability of the 455-0004 is required.

Q3: Are there any compliance or regulatory differences between these parts?

A: Both parts share identical RoHS compliance status, ECCN classification (5A002A1 LAI), and HTSUS code (8517.62.0090). No compliance or regulatory barriers exist for substitution from a documentation perspective.

Q4: What is the packaging difference, and does it affect substitution?

A: The 455-0004 packaging is not specified in available documentation. The 455-0002 is supplied in Bulk packaging. Confirm packaging requirements for your procurement and assembly processes before finalizing substitution.

Q5: Why is the 455-0004 obsolete while the 455-0002 remains active?

A: Product lifecycle decisions are manufacturer-driven. The 455-0002's active status and higher inventory availability (1204 Pcs versus 867 Pcs for the obsolete 455-0004) indicate that the single-band 868MHz configuration meets current market demand, particularly for European IoT deployments.
