Substitute Part Grouping Explanation

Substitution eligibility for the RN2483A-I/RM103 is determined by strict equivalence across the following critical parameters:

• RF Family/Standard: General ISM < 1GHz
• Protocol: LoRa™
• Frequency Bands: 433MHz, 868MHz
• Modulation: FSK, GFSK
• Data Rate: 300kbps
• Power Output: 14dBm
• Sensitivity: -146dBm
• Serial Interfaces: I2C, SPI, UART
• Voltage Supply Range: 2.1V ~ 3.6V
• Mounting Type: Surface Mount
• Package Type: Module with Castellation
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Compliance: ROHS3 Compliant

The RN2483A-I/RM104 meets all substitution criteria as a direct equivalent from the same manufacturer, differing only in packaging configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The RN2483A-I/RM104 is a direct functional equivalent to the RN2483A-I/RM103. Both parts share identical electrical and mechanical specifications across all critical RF, power, and interface parameters. The primary distinction is product status: the RN2483A-I/RM103 is discontinued, while the RN2483A-I/RM104 maintains active production status with significantly higher inventory availability (10,347 units versus 820 units).

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production applications. The RN2483A-I/RM104 is supplied in Tray packaging, which is standard for production volume applications.

Frequently Asked Questions (FAQ)

Q: Can the RN2483A-I/RM104 replace the RN2483A-I/RM103 in existing designs?

A: Yes. The RN2483A-I/RM104 is electrically and mechanically equivalent across all specified parameters. No design modifications are required for substitution.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (discontinued versus active) and packaging configuration. The RN2483A-I/RM103 uses an unspecified packaging format, while the RN2483A-I/RM104 is supplied in Tray packaging. Firmware versions differ (1.0.3 versus 1.0.4), but both support the same LoRa™ protocol and RF specifications.

Q: Are there any compatibility concerns with the firmware version difference?

A: Firmware versions 1.0.3 and 1.0.4 are both supported by Microchip Technology for the RN2483 base product line. Both versions maintain compatibility with the same serial interfaces (I2C, SPI, UART) and protocol implementations.

Q: Why is the RN2483A-I/RM103 discontinued?

A: Product discontinuation decisions are made by manufacturers based on production and market factors. The RN2483A-I/RM104 remains in active production and is the recommended source for new component procurement.

Q: What is the inventory status for these parts?

A: The RN2483A-I/RM103 has 820 units in stock (limited availability). The RN2483A-I/RM104 has 10,347 units in stock, providing significantly greater availability for production applications.

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both parts operate across the -40°C to 85°C temperature range, meeting industrial application requirements.
