Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ENW-49C02A3KF is determined by the following critical parameters:

RF Compatibility Requirements:

• WiFi protocol standard (802.11b/g/n minimum)
• Operating frequency band (2.4GHz)
• Sensitivity performance (-97dBm or better)
• Power output capability (16dBm or greater)

Electrical Compatibility Requirements:

• Supply voltage range (3V ~ 3.6V)
• Serial interface support (UART minimum)
• Operating temperature range (-40°C ~ 85°C)

Physical & Regulatory Requirements:

• Surface mount packaging
• RoHS3 compliance
• MSL rating 3 or better

The ENW-49D01A1KF meets all substitution criteria as an active product within the same ENW-49 base product family, offering enhanced performance specifications while maintaining electrical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ENW-49D01A1KF is the qualified substitute for the obsolete ENW-49C02A3KF based on the following engineering criteria:

Product Status & Availability: The ENW-49D01A1KF maintains active manufacturing status with 2032 units in current inventory, ensuring long-term supply continuity compared to the obsolete ENW-49C02A3KF.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL ratings, satisfying regulatory requirements for equivalent substitution.

Electrical Compatibility: Supply voltage (3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and sensitivity performance (-97dBm) are identical. The substitute provides enhanced data rate (150Mbps vs. 72Mbps) and power output (19.5dBm vs. 16dBm), meeting or exceeding the original specification.

Interface Compatibility: The ENW-49D01A1KF includes UART as part of an expanded serial interface set, maintaining backward compatibility with existing UART-based designs.

Physical Considerations: The substitute uses a different package footprint (87-SMD Module vs. 72-SMD Module) and antenna implementation (PCB Trace vs. Integrated Chip). PCB layout redesign and antenna tuning validation are required for implementation.

Transmit Current: The substitute exhibits lower transmit current (175mA ~ 260mA vs. 310mA), reducing power supply requirements. Verify that existing power delivery infrastructure remains adequate for the application.

Frequently Asked Questions (FAQ)

Q: Can the ENW-49D01A1KF directly replace the ENW-49C02A3KF without PCB modifications?

A: No. The substitute uses a different package footprint (87-SMD Module vs. 72-SMD Module) and antenna type (PCB Trace vs. Integrated Chip). PCB layout redesign is required. Antenna tuning and impedance matching validation are necessary before production implementation.

Q: Are the serial interfaces compatible between these parts?

A: Yes. The ENW-49D01A1KF includes UART as part of its expanded interface set, maintaining compatibility with designs using UART communication. Additional interfaces available on the substitute (SPI, I2C, GPIO, etc.) are optional and do not affect existing UART implementations.

Q: What is the impact of the different antenna types on system performance?

A: The original part uses an integrated chip antenna, while the substitute uses PCB trace antenna. PCB trace antennas require careful layout design and impedance matching. Sensitivity performance is identical (-97dBm), but antenna efficiency depends on PCB implementation. RF performance validation is required during redesign.

Q: Is the lower transmit current of the substitute a concern?

A: The substitute transmit current (175mA ~ 260mA) is lower than the original (310mA), reducing power supply stress. This is advantageous for power-constrained applications. Verify that the reduced current does not impact transmit power output requirements for your specific link budget.

Q: Are both parts RoHS compliant?

A: Yes. Both the ENW-49C02A3KF and ENW-49D01A1KF are ROHS3 compliant with identical MSL ratings (3, 168 Hours), satisfying regulatory requirements for equivalent substitution.

Q: What is the lead time for the ENW-49D01A1KF?

A: The ENW-49D01A1KF is an active product with 2032 units in current inventory, providing immediate availability. The obsolete ENW-49C02A3KF has 1017 units remaining in stock with no future manufacturing planned.

Q: Can I use the ENW-49D01A1KF in existing designs without firmware changes?

A: Firmware compatibility depends on your application. The substitute supports the same WiFi protocols (802.11b/g/n) and UART interface, but enhanced features (additional serial interfaces, higher data rate) may require firmware updates to fully utilize. Existing UART-based firmware should function without modification, though testing is required.
