WB-USB-09SX-A Equivalent & Substitute Parts

Part Overview

The WB-USB-09SX-A is a 900 MHz 1W power wireless bridge RF transceiver designed for ISM band applications with USB interface connectivity. This component operates at 115.2 kbps data rate and provides -113 dBm sensitivity across a 7V to 30V supply voltage range. The product is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain system functionality and ensure long-term component availability for new designs and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WB-USB-09SX-A are identified based on strict equivalence of the following critical parameters:

• Frequency: 900 MHz ISM band operation
• Function: RF Transceiver, Bridge topology
• Power Output: 1W transmission capability
• Sensitivity: -113 dBm reception threshold
• Data Rate: 115.2 kbps maximum throughput
• Voltage Supply: 7V ~ 30V operating range
• Modulation/Protocol: ISM standard compliance

The primary substitute identified is the WB-RS232-09SX-A, which maintains identical RF performance characteristics, frequency band, power output, sensitivity, and data rate specifications. The key distinction is the interface type: the substitute employs RS-232 serial communication instead of USB. This substitution is valid when system architecture permits RS-232 interface integration or when USB-to-RS-232 conversion is implemented at the application level.

Engineering Selection Recommendations

The WB-RS232-09SX-A is the manufacturer-recommended substitute for the obsolete WB-USB-09SX-A. Selection of this substitute is appropriate based on the following engineering criteria:

• Active product status ensures ongoing availability, technical support, and compliance with current regulatory requirements
• Identical RF performance parameters (frequency, power output, sensitivity, data rate) guarantee equivalent wireless functionality
• Matching voltage supply range (7V ~ 30V) permits direct power supply integration
• Current ECCN classification (5A002A1) and HTSUS code (8517.62.0090) reflect active product status and regulatory compliance
• Interface substitution from USB to RS-232 requires system-level integration assessment to determine compatibility with existing host controllers or implementation of appropriate serial communication interfaces

Frequently Asked Questions (FAQ)

Q: Can the WB-RS232-09SX-A directly replace the WB-USB-09SX-A without modifications?

A: Direct physical replacement is not possible due to interface differences. The WB-USB-09SX-A uses USB communication, while the WB-RS232-09SX-A uses RS-232 serial communication. System integration must accommodate this interface change through appropriate host controller configuration or serial communication adapter implementation.

Q: Are the RF performance characteristics identical between these parts?

A: Yes. Both parts operate at 900 MHz frequency, deliver 1W output power, provide -113 dBm sensitivity, and support 115.2 kbps data rate. RF performance is equivalent across all specified parameters.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates the WB-RS232-09SX-A is currently manufactured, supported by the vendor, and compliant with current regulatory and export control requirements. This ensures long-term availability and technical support for new designs and system maintenance.

Q: Are there voltage supply compatibility concerns?

A: No. Both parts operate across the identical 7V to 30V supply voltage range, permitting direct power supply integration without modification.

Q: What does the ECCN classification change indicate?

A: The change from OBSOLETE to 5A002A1 reflects the active regulatory status of the substitute part. The ECCN 5A002A1 classification applies to RF components and requires compliance with export control regulations. This is standard for active wireless transceiver products.
