Key Parameters

Substitute Part Grouping Explanation

Substitution of the BISM02BI-NA is determined by the following critical parameters:

RF Compatibility Requirements:

• RF Family/Standard: Bluetooth
• Protocol: Bluetooth v2.0, Class 1
• Frequency: 2.4GHz
• Serial Interface: UART

Physical & Environmental Compatibility:

• Mounting Type: Surface Mount
• Package Type: Module
• Operating Temperature Range: -40°C ~ 85°C
• MSL Rating: 3 (168 Hours)

Electrical Interface Compatibility:

• Antenna connector type (U.FL)
• Supply voltage overlap capability
• UART serial communication protocol

The BT730-SC qualifies as a direct substitute based on matching RF standard (Bluetooth v2.0, Class 1), frequency band (2.4GHz), serial interface (UART), surface mount packaging, operating temperature range, and MSL rating. Both parts utilize U.FL antenna connectors and operate within compatible environmental specifications.

Engineering Selection Recommendations

BT730-SC Substitution Basis:

The BT730-SC is a qualified substitute for the BISMS02BI-NA based on the following engineering criteria:

1. RF Protocol Compatibility: Both modules implement Bluetooth v2.0, Class 1 standard at 2.4GHz frequency band with UART serial interface, ensuring protocol-level compatibility.

2. Physical Integration: Both modules are surface-mount packaged with U.FL antenna connectors and identical operating temperature range (-40°C ~ 85°C) and MSL rating (3, 168 Hours).

3. Supply Voltage Overlap: Operating voltage ranges overlap at 3.3V to 5V, enabling direct substitution within this common operating window.

4. Regulatory Compliance: Both parts share identical ECCN (5A002A1 LAI) and HTSUS (8517.62.0090) classifications. BT730-SC carries ROHS3 Compliance certification.

5. Active Product Status: BT730-SC maintains Active product status with confirmed inventory availability (1253 Pcs), addressing supply continuity for obsolete BISMS02BI-NA.

Design Considerations:

• BT730-SC requires external antenna selection and integration, whereas BISMS02BI-NA includes integrated chip antenna. PCB layout modification for antenna matching network is required.
• BT730-SC delivers enhanced performance specifications: 2.1Mbps data rate (versus 300kbps), 18dBm output power (versus 6dBm), and -87dBm sensitivity (versus -84dBm).
• Supply voltage design must operate within 3.3V to 5V range to accommodate BT730-SC specifications.
