Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 455-0003 is determined by the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Laird Connectivity Inc.
• Base Product Number: 455-0 (same product family)
• Function: Temperature & Humidity Sensor
• Modulation/Protocol: Bluetooth v4.2 and LoRaWAN support
• RoHS Compliance: RoHS Compliant status
• ECCN Classification: 5A002A1 LAI

Frequency Band Compatibility: The 455-0003 supports three frequency bands (868MHz, 915MHz, 2.4GHz). Substitute parts must support at least the frequency bands required for the target application. The 455-0001 operates at 915MHz, which is a subset of the main part's frequency coverage.

Product Status Consideration: The 455-0003 is Obsolete. The 455-0001 is Active, making it the appropriate substitute for ongoing production and new designs.

Parameter Comparison

Engineering Selection Recommendations

For 915MHz Applications: The 455-0001 is a direct substitute for the obsolete 455-0003 when the application operates exclusively at 915MHz. Both parts maintain identical Bluetooth v4.2 and LoRaWAN protocol support, RoHS compliance, and ECCN classification. The 455-0001 is actively manufactured and available in production quantities.

For Multi-Frequency Applications (868MHz or 2.4GHz): If the application requires 868MHz or 2.4GHz frequency support in addition to 915MHz, the 455-0001 does not provide equivalent frequency coverage. In such cases, alternative Laird Connectivity Sentrius™ series components within the 455-0 base product family should be evaluated for frequency band compatibility.

Compliance and Regulatory: Both the 455-0003 and 455-0001 are RoHS Compliant and share identical ECCN classification (5A002A1 LAI), ensuring regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can the 455-0001 replace the 455-0003 in all applications?

A: The 455-0001 is a suitable substitute only for applications operating at 915MHz. The 455-0003 supports three frequency bands (868MHz, 915MHz, 2.4GHz), while the 455-0001 supports only 915MHz. If your application requires 868MHz or 2.4GHz operation, the 455-0001 is not compatible.

Q: What is the primary reason for substitution?

A: The 455-0003 is classified as Obsolete. The 455-0001 is an Active product from the same manufacturer and product series, ensuring continued availability and support for new designs and production.

Q: Are there packaging differences between these parts?

A: The 455-0001 is supplied in Bulk packaging. The packaging specification for the 455-0003 is not provided in the technical data. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 455-0003 and 455-0001 are RoHS Compliant and share the same ECCN classification (5A002A1 LAI), ensuring equivalent regulatory compliance.

Q: What protocols do these sensors support?

A: Both parts support Bluetooth v4.2 and LoRaWAN protocols, enabling dual-mode wireless communication for IoT applications.

Q: Is the 455-0001 suitable for general-purpose IoT applications?

A: Yes. The 455-0001 is rated for General Purpose and IoT Finished Device applications, matching the application scope of the 455-0003.
