Key Parameters

Substitute Part Grouping Explanation

Substitution of the RX5500 is determined by the following critical parameters:

• Frequency Compatibility: Operating frequency must align with 433MHz ISM band specifications
• Modulation Support: ASK/OOK modulation capability required for signal demodulation
• Sensitivity Performance: Receiver sensitivity must meet or exceed -110.5dBm threshold
• Data Rate Capability: Maximum data rate must support 19.2kbps operation
• Supply Voltage Range: Operating voltage window must accommodate 2.2V to 3.7V supply
• Operating Temperature Range: Must function across -40°C to 85°C environment
• Mounting Configuration: Surface mount technology with PCB integration capability

The ATA8202C-PXQW-1 from Microchip Technology qualifies as a substitute based on alignment with these core parameters within the RF receiver category.

Engineering Selection Recommendations

The ATA8202C-PXQW-1 is an active product from Microchip Technology and represents a viable substitute for the obsolete RX5500. The substitute demonstrates improved sensitivity performance at -113dBm compared to the RX5500 at -110.5dBm, and supports equivalent data rate capability at 20kbps. Both devices operate across the same temperature range of -40°C to 85°C and utilize surface mount technology for PCB integration.

Key considerations for selection include supply voltage range compatibility. The RX5500 operates from 2.2V to 3.7V, while the ATA8202C-PXQW-1 operates from 2.7V to 3.3V. Systems designed for the lower voltage threshold of 2.2V require verification of compatibility with the substitute's 2.7V minimum specification.

Receiving current consumption differs between devices, with the RX5500 drawing 3.1mA and the ATA8202C-PXQW-1 drawing 6.9mA. Power budget analysis is necessary for battery-powered applications.

Package configuration differs between the 20-SMD module of the RX5500 and the 24-VQFN package of the substitute, requiring PCB layout modification. The ATA8202C-PXQW-1 carries ROHS3 compliance and maintains REACH Unaffected status, consistent with regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the ATA8202C-PXQW-1 directly replace the RX5500 without PCB modification?

A: No. The RX5500 uses a 20-SMD module package while the ATA8202C-PXQW-1 uses a 24-VQFN package. PCB layout and footprint redesign is required for physical integration.

Q: What is the frequency difference between these devices?

A: The RX5500 operates at 433.92MHz while the ATA8202C-PXQW-1 operates at 433MHz. Both devices function within the 433MHz ISM band for RF receiver applications.

Q: Are there supply voltage compatibility concerns?

A: Yes. The RX5500 minimum supply voltage is 2.2V, while the ATA8202C-PXQW-1 minimum is 2.7V. Systems operating below 2.7V require alternative solutions.

Q: How do the sensitivity specifications compare?

A: The ATA8202C-PXQW-1 provides superior sensitivity at -113dBm compared to the RX5500 at -110.5dBm, indicating improved receiver performance for weak signal detection.

Q: What is the impact of increased current consumption?

A: The ATA8202C-PXQW-1 draws 6.9mA versus the RX5500 at 3.1mA during reception. Battery-powered designs must account for this 2.2x increase in power consumption.

Q: Are both devices compliant with environmental regulations?

A: Both devices maintain REACH Unaffected status. The ATA8202C-PXQW-1 is ROHS3 compliant. The RX5500 moisture sensitivity level is 1 (Unlimited), while the substitute is MSL 2 (1 Year), requiring appropriate storage and handling protocols.
