Is there a pin-compatible replacement for VG6328A?

No, none of the reviewed candidates are pin-compatible with the 5-pin VG6328A module. A board redesign is required for any replacement.

What risks should I check before replacing VG6328A?

Key risks include: 1) Physical mismatch (pinout and dimensions). 2) Protocol differences (dual-mode BT 5.3 vs. BLE-only or older versions). 3) Electrical incompatibility, especially supply voltage range. 4) Firmware changes for the new module's command set.

VG6328A Alternatives, Datasheet & Cross Reference | Vollgo

VG6328A is a dual-mode Bluetooth 5.3 module with a UART interface. Finding a direct drop-in replacement is challenging; available functional alternatives require significant engineering review and redesign of hardware and firmware.

AI replacement insight

Package riskhigh

No candidates match the 5-pin, 16x13.6mm module footprint.

Firmware riskhigh

Alternatives are not dual-mode or use older BT versions, requiring new driver and protocol handling.

Electrical riskmedium

Supply voltage ranges are narrower on all candidates, requiring power supply verification.

Can it be replaced directly?

No, there are no direct pin-compatible replacements for the VG6328A among the candidates reviewed. All alternatives require significant hardware and firmware changes.

Best replacement path

Evaluate other dual-mode Bluetooth 5.3+ modules with UART interfaces, paying close attention to pinout, package size, and supply voltage requirements. The reviewed candidates are not ideal.

Main risk

The main risks are physical incompatibility (pinout and package) and functional downgrades (losing BR/EDR support or using an older Bluetooth version), requiring a full redesign.

Recommended alternatives

A BLE-only functional alternative with different pinout, package, and a restrictive supply voltage, requiring redesign.
