RF300PD1 Equivalent & Substitute Parts

Part Overview

The RF300PD1 is a General ISM < 1GHz transceiver module manufactured by Synapse Wireless as part of the SNAP® RF Engine® series. This through-hole module operates at 915MHz with FHSS modulation and delivers 20dBm output power. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system redesign, legacy support, or component sourcing in applications requiring ISM band RF communication.

• Data Rate: RF300PD1 supports 150kbps; XBP9B-XCST-022 supports 20kbps
• Power Output: RF300PD1 delivers 20dBm; XBP9B-XCST-022 delivers 24dBm
• Serial Interfaces: RF300PD1 supports I2C, SPI, UART; XBP9B-XCST-022 supports UART only
• Product Status: RF300PD1 is Obsolete; XBP9B-XCST-022 is Active

Parameter Comparison

Engineering Selection Recommendations

The XBP9B-XCST-022 is the manufacturer-recommended substitute for the obsolete RF300PD1. Selection of this alternative is supported by:

• Product Status: The XBP9B-XCST-022 maintains Active status with ongoing manufacturer support, whereas the RF300PD1 is Obsolete and no longer manufactured.
• Compliance & Certifications: The XBP9B-XCST-022 is RoHS Compliant and REACH Unaffected, providing regulatory alignment for new designs and legacy replacements.
• RF Compatibility: Both modules operate within the General ISM < 1GHz band using FHSS modulation, ensuring protocol-level compatibility in ISM applications.
• Physical Interface Compatibility: Identical RP-SMA antenna interface and Through Hole mounting enable direct mechanical substitution in existing PCB layouts.
• Environmental Specifications: Matching operating temperature range (-40°C ~ 85°C) and MSL rating (1, Unlimited) ensure equivalent reliability in deployed environments.

Frequently Asked Questions (FAQ)

Q: Can the XBP9B-XCST-022 directly replace the RF300PD1 in existing designs?

A: Physical and RF-level substitution is possible due to matching antenna interface (RP-SMA), mounting type (Through Hole), and ISM band operation (FHSS modulation). However, firmware and interface adaptation may be required due to differences in serial interface support (RF300PD1 supports I2C and SPI; XBP9B-XCST-022 supports UART only) and data rate specifications (150kbps vs. 20kbps).

Q: What is the frequency difference between these modules?

A: The RF300PD1 operates at 915MHz, while the XBP9B-XCST-022 operates at 920MHz. Both frequencies fall within the ISM < 1GHz band and use FHSS modulation. Frequency compatibility depends on regional regulatory approval and application-specific channel planning.

Q: Are there differences in power consumption between these modules?

A: Yes. The XBP9B-XCST-022 specifies receiving current at 26mA and transmitting current at 215mA with a supply voltage range of 2.4V ~ 3.6V. The RF300PD1 does not provide current specifications in the available data. Power budget analysis is required for battery-powered applications.

Q: What packaging options are available?

A: The RF300PD1 is supplied in Bulk packaging (standard for through-hole modules). The XBP9B-XCST-022 is also supplied in Bulk packaging. Both modules are classified as Package/Case type Module with MSL 1 (Unlimited) moisture sensitivity.

Q: Is the XBP9B-XCST-022 suitable for new product designs?

A: Yes. The XBP9B-XCST-022 is Active status with RoHS Compliance and REACH Unaffected certification, making it appropriate for new designs requiring ISM < 1GHz RF communication with FHSS modulation and RP-SMA antenna interface.
