Key Parameters

Substitute Part Grouping Explanation

The LBEE5KL1YN-814 qualifies as a substitute for the LBEE5KL1DX-883 based on the following alignment of critical parameters:

Mechanical Compatibility: Both parts use identical 46-SMD Module packaging and surface mount mounting type, ensuring PCB layout compatibility without redesign.

RF Performance: Both operate in the 2.4GHz band with identical 65Mbps data rate and support 802.11b/g/n and Bluetooth protocols. The substitute supports Bluetooth v5.2 versus v5.1 in the main part, representing protocol advancement within the same frequency band.

Electrical Parameters: Current consumption specifications are identical (60mA receiving, 370mA transmitting). Supply voltage range differs slightly (3V ~ 4.8V for substitute versus 3.3V ~ 4.2V for main part), with the substitute offering broader input tolerance.

Regulatory Compliance: Both parts maintain ROHS3 compliance, identical MSL rating of 3 (168 Hours), and matching ECCN and HTSUS classifications.

Product Status: Both parts are active products with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

LBEE5KL1DX-883 Selection: Choose this part when the design specifically requires Bluetooth v5.1 protocol support and the narrower supply voltage range of 3.3V ~ 4.2V aligns with power supply architecture. This part maintains active product status with established supply chain presence.

LBEE5KL1YN-814 Selection: Choose this substitute when design requirements permit Bluetooth v5.2 protocol, when broader input voltage tolerance (3V ~ 4.8V) provides power supply flexibility, or when higher transmit power output (19dBm versus 17dBm) is beneficial. The substitute offers additional serial interface options (PCM, SDIO) beyond the main part's UART interface. Both parts maintain identical regulatory compliance and thermal operating range.

Both parts are ROHS3 compliant and carry matching ECCN and HTSUS classifications, ensuring equivalent regulatory treatment in procurement and export documentation.

Frequently Asked Questions (FAQ)

Q: Can LBEE5KL1YN-814 directly replace LBEE5KL1DX-883 on existing PCBs?

A: Yes. Both parts use identical 46-SMD Module packaging and surface mount configuration. No PCB layout modifications are required for mechanical and electrical interface compatibility.

Q: What are the key differences between these parts?

A: The substitute (LBEE5KL1YN-814) offers Bluetooth v5.2 versus v5.1, broader supply voltage range (3V ~ 4.8V versus 3.3V ~ 4.2V), higher transmit power (19dBm versus 17dBm), additional serial interfaces (PCM and SDIO in addition to UART), and specified receiver sensitivity (-95dBm). Current consumption and data rate remain identical.

Q: Are there supply voltage compatibility concerns?

A: The main part operates at 3.3V ~ 4.2V while the substitute accepts 3V ~ 4.8V. If your power supply delivers voltage within the main part's range, the substitute will operate within specification. The substitute's broader tolerance provides additional margin for power supply variations.

Q: Do both parts support the same wireless protocols?

A: Both support 802.11b/g/n and Bluetooth protocols. The main part specifies Bluetooth v5.1 while the substitute specifies Bluetooth v5.2. Both operate in the 2.4GHz band with identical 65Mbps data rate.

Q: Are there regulatory or compliance differences?

A: No. Both parts are ROHS3 compliant with identical MSL ratings (3, 168 Hours), ECCN classification (5A992C), and HTSUS code (8517.62.0090). Regulatory treatment is equivalent.

Q: What additional interfaces does the substitute provide?

A: The LBEE5KL1YN-814 includes PCM and SDIO serial interfaces in addition to UART, providing design flexibility for different host processor integration requirements.
