Key Parameters

Substitute Part Grouping Explanation

Substitution of the BC0401PC08-IXB-R is determined by the following critical parameters:

• RF Family/Standard: Bluetooth protocol compatibility
• Frequency Band: 2.4GHz operation
• Type: Integrated TxRx + MCU architecture
• Mounting Type: Surface Mount capability
• Package Category: WLCSP (Wafer Level Chip Scale Package)
• Compliance: RoHS3 and REACH status alignment
• Environmental Rating: Operating temperature range and MSL classification

The CSR8510A10-ICXR-R qualifies as a substitute based on shared Bluetooth RF family, 2.4GHz frequency, integrated TxRx+MCU architecture, surface mount capability, WLCSP packaging category, and equivalent compliance certifications. Differences in protocol version, data rate, and package footprint represent design trade-offs requiring system-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The CSR8510A10-ICXR-R is an active product with current manufacturing support and inventory availability, addressing the obsolescence status of the BC0401PC08-IXB-R. Both components maintain ROHS3 compliance and equivalent MSL ratings, ensuring environmental and regulatory alignment.

Selection of the CSR8510A10-ICXR-R requires accommodation of the following design considerations:

• Protocol upgrade from Bluetooth v2.1 +EDR to Bluetooth v4.0
• Package footprint reduction from 47-WLCSP to 28-WLCSP
• Supply voltage specification change from 2.2V–4.2V to 3.3V
• Enhanced data rate capability (12Mbps vs. 3Mbps)
• Improved receiver sensitivity (-91dBm vs. -86dBm)
• Additional serial interface options (I2S, SPI, USB)

These parameters are provided for system-level compatibility assessment. Active product status and established supply chain availability support long-term design continuity.

Frequently Asked Questions (FAQ)

Q: Can the CSR8510A10-ICXR-R directly replace the BC0401PC08-IXB-R in existing designs?

A: Direct replacement requires evaluation of protocol compatibility, supply voltage requirements, and package footprint constraints. The CSR8510A10-ICXR-R operates at 3.3V (vs. 2.2V–4.2V range) and uses a smaller 28-WLCSP package (vs. 47-WLCSP). PCB layout and power supply modifications may be necessary.

Q: What are the key differences in Bluetooth protocol support?

A: The BC0401PC08-IXB-R implements Bluetooth v2.1 +EDR with Class 2 and 3 power levels. The CSR8510A10-ICXR-R implements Bluetooth v4.0. Protocol differences affect interoperability with legacy Bluetooth devices and power consumption characteristics.

Q: Are both components RoHS compliant?

A: Yes. Both the BC0401PC08-IXB-R and CSR8510A10-ICXR-R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the impact of package size reduction?

A: The CSR8510A10-ICXR-R uses a 28-WLCSP package (2.57x3.21mm) compared to the 47-WLCSP package (3.75x3.95mm) of the BC0401PC08-IXB-R. This reduction requires PCB layout redesign and may affect thermal management considerations.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both components carry MSL rating 3 (168 hours), indicating equivalent moisture handling and storage requirements during manufacturing and assembly processes.
