Sierra Wireless 1104845 RF TXRX Module IOT Equivalent & Substitute Parts

Part Overview

The Sierra Wireless 1104845 is an RF TXRX Module IOT transceiver module belonging to the HL - AirPrime® series. This component is classified as Active product status and is currently available in inventory (864 Pcs New Original In Stock). The module is supplied in Tape & Reel (TR) packaging format.

Identification of equivalent and substitute parts becomes necessary when the primary part number reaches end-of-life status, when packaging format requirements change, or when inventory availability fluctuates. The substitute part HL7812_1105036 is identified as the manufacturer-recommended alternative, though it carries an Obsolete product status designation.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part number 1104845 and the alternative HL7812_1105036 is based on the following criteria:

Manufacturer Alignment: Both components are manufactured by Sierra Wireless, ensuring design compatibility and support consistency.

Series Compatibility: Both parts belong to the HL - AirPrime® series, confirming functional and electrical alignment within the product family.

Component Classification: Both are classified as transceiver modules with surface mount mounting type, indicating mechanical and electrical interchangeability at the board level.

Packaging Consideration: The main part is supplied in Tape & Reel (TR) packaging, while the substitute is available in Cut Tape (CT) & Digi-Reel® packaging. This difference affects handling and assembly processes but does not impact electrical performance.

Moisture Sensitivity: The main part carries MSL 3 (168 Hours), while the substitute carries MSL 1 (Unlimited). This indicates the substitute part has less stringent moisture handling requirements.

Parameter Comparison

Engineering Selection Recommendations

Active Product Status Consideration: The main part number 1104845 maintains Active product status, indicating ongoing manufacturer support and availability. The substitute part HL7812_1105036 carries Obsolete status, which restricts its use to legacy system maintenance or replacement scenarios only.

Substitution Direction: Forward substitution from 1104845 to HL7812_1105036 is not recommended for new designs due to the Obsolete status of the substitute part. Reverse substitution from HL7812_1105036 to 1104845 is appropriate for systems requiring extended product lifecycle support.

Packaging Format Impact: Selection between these parts must account for assembly line compatibility. The main part's Tape & Reel (TR) format differs from the substitute's Cut Tape (CT) & Digi-Reel® format, requiring process validation before implementation.

Moisture Handling Requirements: The substitute part's superior moisture sensitivity rating (MSL 1 versus MSL 3) provides relaxed storage and handling requirements, which may offer operational advantages in certain manufacturing environments.

Compliance and Certification: Both parts are manufactured by Sierra Wireless within the HL - AirPrime® series. The substitute part includes ECCN and HTSUS classifications (ECCN: 5A992C SC; HTSUS: 8517.62.0090), which must be verified for regulatory compliance in the target application region.

Frequently Asked Questions (FAQ)

Q: Can the HL7812_1105036 be used as a direct replacement for the 1104845 in new designs?

A: No. The substitute part carries Obsolete product status, making it unsuitable for new design implementations. The 1104845 should be used for new applications requiring long-term support.

Q: What is the primary difference between these two part numbers?

A: Both are Sierra Wireless HL - AirPrime® series transceiver modules with surface mount construction. The main differences are packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), product status (Active versus Obsolete), and moisture sensitivity level (MSL 3 versus MSL 1).

Q: Are there electrical performance differences between these parts?

A: The provided specifications do not indicate electrical performance differences. Both are classified as transceiver modules within the same manufacturer series. The substitute part includes additional detailed specifications (frequency bands, protocols, interfaces, power output) not provided for the main part.

Q: What does MSL 3 (168 Hours) mean compared to MSL 1 (Unlimited)?

A: MSL 3 (168 Hours) indicates the component must be used within 168 hours of exposure to moisture after packaging is opened. MSL 1 (Unlimited) means the component has no time restriction for moisture exposure, providing greater flexibility in storage and handling.

Q: Can the packaging format difference affect circuit board assembly?

A: Yes. Tape & Reel (TR) packaging and Cut Tape (CT) & Digi-Reel® packaging require different handling equipment and processes. Assembly line compatibility must be verified before switching between these formats.

Q: Is the HL7812_1105036 still available for purchase?

A: The substitute part shows 2806 Pcs New Original In Stock, indicating current availability despite its Obsolete status. However, Obsolete designation means no future production is planned, and inventory will eventually deplete.

Q: What should be done if the 1104845 becomes unavailable?

A: Contact Sierra Wireless directly for end-of-life transition guidance. The HL7812_1105036 may serve as a temporary solution for legacy system support, but alternative current-production parts should be identified for long-term applications.
