Key Parameters

Substitute Part Grouping Explanation

The RF220UF1 is identified as a direct substitute based on the following core compatibility criteria:

Maintained Parameters:

• Manufacturer: Synapse Wireless (same manufacturer ensures design continuity)
• RF Family/Standard: 802.15.4 (identical wireless protocol)
• Frequency: 2.4GHz (same operating frequency band)
• Data Rate: 2Mbps (identical throughput specification)
• Antenna Type: Integrated, Chip + U.FL (same connector interface)
• Operating Temperature: -40°C ~ 85°C (identical thermal range)
• Memory: 128kB Flash, 58kB RAM (core memory capacity maintained)
• Voltage Supply: 2V ~ 3.6V (overlapping supply range; RF200PU1 minimum 1.8V)
• HTSUS Code: 8517.62.0090 (same tariff classification)

Differences Requiring Evaluation:

• Mounting Type: RF200PU1 is surface mount; RF220UF1 is through hole
• Package: RF200PU1 is module format; RF220UF1 is 24-DIP module
• Power Output: RF200PU1 outputs 3dBm; RF220UF1 outputs 20dBm
• Sensitivity: RF200PU1 is -100dBm; RF220UF1 is -103dBm
• Current Draw: RF220UF1 exhibits higher transmit current (150mA vs. 14.5mA ~ 22.5mA)
• Serial Interfaces: RF200PU1 supports I2C, JTAG, SPI, UART; RF220UF1 supports SPI, UART only
• Product Status: RF200PU1 is obsolete; RF220UF1 is active
• RoHS Status: RF200PU1 is RoHS Compliant; RF220UF1 is ROHS3 Compliant

Parameter Comparison

Engineering Selection Recommendations

The RF220UF1 serves as a functional substitute for the obsolete RF200PU1 within the Synapse Wireless 802.15.4 product family. Both modules maintain core 802.15.4 protocol compliance, identical 2.4GHz frequency operation, and equivalent 2Mbps data rate specifications.

Substitution Feasibility:

The RF220UF1 is suitable for applications where the following conditions are met:

• PCB design accommodates through-hole mounting in place of surface mount assembly
• System power budget can accommodate increased transmit current (150mA vs. 14.5mA ~ 22.5mA range)
• Application does not require I2C or JTAG interfaces; SPI and UART connectivity is sufficient
• System voltage supply minimum of 2V is acceptable (RF200PU1 operates to 1.8V minimum)
• Absence of 4kB EEPROM in RF220UF1 does not impact application requirements
• Higher output power (20dBm vs. 3dBm) and improved sensitivity (-103dBm vs. -100dBm) are compatible with system design

Compliance Considerations:

Both modules maintain RoHS compliance. The RF220UF1 meets ROHS3 standard, representing current regulatory alignment. The RF200PU1's obsolete status necessitates transition to active product lines for ongoing supply chain support.

Frequently Asked Questions (FAQ)

Q: Can RF220UF1 directly replace RF200PU1 in existing designs?

A: Direct replacement requires PCB redesign to accommodate through-hole mounting instead of surface mount. The RF220UF1 24-DIP package footprint differs from the RF200PU1 module format. Additionally, applications utilizing I2C or JTAG interfaces must be redesigned to use SPI or UART only.

Q: What is the impact of increased transmit current in RF220UF1?

A: The RF220UF1 transmit current of 150mA represents a significant increase from the RF200PU1 range of 14.5mA ~ 22.5mA. Power supply design and battery capacity calculations must be reevaluated for applications transitioning to RF220UF1.

Q: Are the antenna connectors compatible between RF200PU1 and RF220UF1?

A: Both modules feature integrated antennas with U.FL connectors. External antenna compatibility depends on impedance matching and connector type, which are not specified in the provided parameters.

Q: Does the higher output power of RF220UF1 affect regulatory compliance?

A: Both modules operate within the 2.4GHz ISM band under 802.15.4 protocol. Output power differences (3dBm vs. 20dBm) may affect regional regulatory compliance depending on jurisdiction-specific power limits. Regulatory assessment is required for specific applications.

Q: What is the significance of the EEPROM difference?

A: The RF200PU1 includes 4kB EEPROM; the RF220UF1 does not specify EEPROM capacity. Applications requiring non-volatile storage beyond flash memory must evaluate alternative storage solutions or confirm EEPROM availability in RF220UF1 through manufacturer documentation.

Q: Can RF220UF1 operate at 1.8V minimum supply voltage?

A: No. The RF220UF1 minimum supply voltage is 2V, compared to RF200PU1 at 1.8V. Systems designed for 1.8V operation require voltage regulation or alternative component selection.
