RN4677-V/RM112 Equivalent & Substitute Parts Reference

Part Overview

RN4677-V/RM112 is an obsolete Bluetooth v4.0 Dual Mode, Class 2 transceiver module from Microchip Technology. It operates at 2.4GHz with an integrated chip antenna, UART serial interface, and supports surface mount assembly. Due to its obsolescence, identifying substitute Bluetooth transceiver modules with matching key electrical and mechanical parameters is essential for maintaining continuity in design, repair, and production.

Key Parameters

Substitute Part Grouping Explanation

The substitute Bluetooth transceiver modules are selected exclusively based on matching the following key parameters: Bluetooth protocol (dual mode operation), RF frequency (2.4GHz), UART serial interface, output power, sensitivity, integrated chip antenna, supply voltage range, receive and transmit current, surface mount package, identical operating temperature range, and same 33-SMD module mechanical format. Only parts from the same manufacturer and known compliance status are considered, aligned with the original obsolete part.

Parameter Comparison

Engineering Selection Recommendations

RN4677-V/RM112 is classified as obsolete. Substitute modules RN4678-VB/RM122 and RN4678APL-VB/RM122 are active and include RoHS3 and REACH compliance. Selection within this substitute group should follow non-obsolescence and current compliance standards. Only select parts with confirmed compliance and available active status.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if RN4678-VB/RM122 or RN4678APL-VB/RM122 are valid substitutes for RN4677-V/RM112?
A1: Substitute suitability is strictly based on compatibility in Bluetooth protocol (dual mode operation), frequency (2.4GHz), UART interface, output power, sensitivity, integrated chip antenna, supply voltage range, receiving and transmitting current, mounting type, operating temperature, and 33-SMD module package.

Q2: Can I substitute RN4677-V/RM112 with RN4678-VB/RM122 or RN4678APL-VB/RM122 without modifying the PCB?
A2: All listed substitute modules use the same 33-SMD module package and surface mount format. Compatibility is established based on these mechanical characteristics alone.

Q3: Are the compliance and environmental statuses of the substitutes equivalent to RN4677-V/RM112?
A3: Both RN4678-VB/RM122 and RN4678APL-VB/RM122 are RoHS3 compliant and REACH unaffected. RN4677-V/RM112 status is provided as obsolete without additional compliance information.

Q4: Do the substitute modules provide the same UART interface and integrated chip antenna as RN4677-V/RM112?
A4: Yes, both substitutes feature a UART interface and integrated chip antenna, matching the main module's interface and antenna requirements.

Q5: Are the current consumption and voltage ranges strictly matched between RN4677-V/RM112 and its substitutes?
A5: Receiving and transmitting current, as well as voltage supply ranges, are within the specified limits provided. Substitution is strictly based on the provided values.
