Key Parameters

Substitute Part Grouping Explanation

The WL1801MODGBMOCT qualifies as a direct substitute based on the following alignment criteria:

Core Compatibility Parameters:

• Manufacturer: Texas Instruments (same OEM)
• RF Standard: Bluetooth with 2.4GHz operation
• Voltage Supply Range: 2.9V ~ 4.8V (identical)
• Sensitivity: -96.3dBm (identical)
• Mounting Type: Surface Mount
• RoHS3 Compliance: Maintained
• Serial Interface: UART supported

Functional Enhancement: The WL1801MODGBMOCT extends protocol support to include Bluetooth 4.2 and WiFi 802.11b/g/n, providing backward compatibility with Bluetooth v4.1 applications while offering additional wireless capabilities. The substitute maintains the same supply voltage window and sensitivity specification, ensuring electrical compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The XWL1801MODGAMOCT is classified as Obsolete, making the WL1801MODGBMOCT the appropriate selection for new designs and production continuity. The substitute maintains Active product status with Texas Instruments, ensuring long-term availability and supply chain stability.

Electrical Compatibility

Both components operate within identical voltage supply ranges (2.9V ~ 4.8V) and maintain equivalent sensitivity specifications (-96.3dBm). The substitute's marginally higher power output (18.5dBm vs. 17.3dBm) and lower minimum current draw during receive and transmit operations provide operational advantages without introducing incompatibility.

Regulatory Compliance

Both parts maintain ROHS3 compliance and carry identical ECCN classification (5A992C), satisfying export control and environmental regulatory requirements. The substitute's REACH Unaffected status provides additional regulatory clarity for European applications.

Temperature Operating Range

The original part supports a wider operating temperature range (-40°C to 85°C) compared to the substitute (-20°C to 70°C). Applications requiring operation below -20°C or above 70°C must evaluate alternative solutions or implement thermal management strategies.

Moisture Sensitivity

The original part carries MSL 2 rating (1 Year shelf life), while the substitute carries MSL 3 rating (168 Hours shelf life). This difference affects storage and handling protocols but does not impact in-service performance.

Frequently Asked Questions (FAQ)

Q: Can WL1801MODGBMOCT directly replace XWL1801MODGAMOCT in existing designs?

A: Yes, for applications operating within the -20°C to 70°C temperature range. Both components share identical voltage supply requirements (2.9V ~ 4.8V), sensitivity (-96.3dBm), and UART serial interface. The substitute supports Bluetooth v4.1 protocol, ensuring backward compatibility with existing firmware and application code.

Q: What are the key differences between these two modules?

A: The WL1801MODGBMOCT extends protocol support to include Bluetooth 4.2 and WiFi 802.11b/g/n, while the XWL1801MODGAMOCT supports only Bluetooth v4.1. The substitute offers lower minimum current consumption during receive (49mA vs. 85mA) and transmit (238mA vs. 420mA) operations. The original part supports a wider operating temperature range (-40°C to 85°C vs. -20°C to 70°C).

Q: Are there packaging differences between these modules?

A: Both components are surface mount modules. The original part specifies 100-FLGA packaging (13.4x13.3mm), while the substitute is designated as a Module without specific footprint dimensions provided. Physical compatibility must be verified against PCB layout requirements and mechanical constraints.

Q: What is the impact of the different MSL ratings?

A: The original part carries MSL 2 (1 Year shelf life), while the substitute carries MSL 3 (168 Hours shelf life). This affects storage conditions and handling protocols. MSL 3 components require more stringent moisture control during storage and have a shorter shelf life before requiring baking procedures. This does not affect performance once the component is soldered into the final assembly.

Q: Why is the original part classified as Obsolete?

A: Texas Instruments has discontinued the XWL1801MODGAMOCT in favor of the WL1801MODGBMOCT, which provides enhanced protocol support and improved power efficiency. The substitute is the recommended replacement for all new designs and production continuity.

Q: Are there temperature-related constraints for substitution?

A: Yes. If your application requires operation below -20°C or above 70°C, the WL1801MODGBMOCT cannot be used as a direct substitute. The original part's extended temperature range (-40°C to 85°C) is required for such applications. Consult alternative component options or implement external thermal management if necessary.

Q: What serial interfaces does each module support?

A: The XWL1801MODGAMOCT supports UART only. The WL1801MODGBMOCT supports both SDIO and UART, providing additional interface flexibility for new designs while maintaining UART compatibility with existing implementations.
