RF Receivers datasheet and documents for RDF1
RF Receivers Overview
The RDF1 is a discontinued RF receiver module manufactured by RF Solutions, designed for operation in the 433.92 MHz frequency band. It supports FM and FSK modulation protocols and utilizes a 20-SIP through-hole package. The module operates on a supply voltage range of 4.5V to 5.5V and features a receive sensitivity of -103dBm. Physical dimensions include a length of 50.5mm and a width of 18.5mm. The operating temperature range is specified from 0°C to +60°C or +70°C depending on the source documentation.
RF Receivers Feature Summary
- Supports FM and FSK modulation protocols for reliable data transmission
- High receive sensitivity of -103dBm for improved signal detection
- Through-hole mounting configuration for PCB integration
- Operates within a standard 4.5V to 5.5V power supply range
RF Receivers Applications
- Remote control systems requiring 433MHz reception
- Wireless sensor networks utilizing FM/FSK protocols
- Industrial monitoring applications with through-hole constraints
RF Receivers Procurement Notes
Verify component obsolescence status prior to procurement as the RDF1 is officially discontinued. Confirm that the manufacturer-recommended substitute ZPT-4RD meets all functional requirements. Ensure compatibility with existing PCB layouts due to potential differences in pinout or physical dimensions between the legacy RDF1 and the replacement ZPT-4RD module. Validate supply chain availability for the substitute part number before finalizing design specifications.
RF Receivers Selection Notes
Select the RDF1 only for maintenance of existing designs where its specific 20-SIP form factor is critical. For new designs, consider the ZPT-4RD as the primary alternative. Evaluate the transition from through-hole to any potential surface-mount options if the substitute differs. Assess whether the 433.92 MHz band aligns with regional regulatory requirements for the target application environment.
RF Receivers Part Context
The RDF1 belongs to the RF Solutions family of radio modules and remote control systems. These components are engineered for wireless communication tasks. The module represents a legacy product line now superseded by newer iterations such as the ZPT-4RD. It serves as a foundational component for older wireless infrastructure projects requiring dedicated RF reception capabilities.
RF Receivers Replacement Considerations
The manufacturer recommends the ZPT-4RD as the direct substitute for the RDF1. Verify mechanical fit and electrical compatibility when transitioning from the RDF1 to the ZPT-4RD. Check datasheet specifications for both parts to ensure performance parameters remain consistent across the upgrade path.
