TK Plug vs Icom Plug: What's the Difference?

If you shop for two‑way radio accessories such as radio earpieces, PTT mics, Bluetooth adapters and programming cables, you will frequently run into two similar‑looking dual‑pin connectors: TK plug and Icom plug.

1. What Are TK Plug and Icom Plug?

1.1 TK Plug (Kenwood Standard Plug)

TK Plug, also known as the Kenwood 2-pin universal plug, is the most popular dual-pin connector in the civilian and commercial two-way radio industry. It is named after Kenwood’s classic TK-series radios and has become a de facto universal standard for most mainstream civilian radio brands.

It features a classic 3.5mm (speaker) + 2.5mm (mic/PTT) dual-pin layout with a standard 11mm center distance between the two pins. With a universal and open specification, it boasts strong compatibility and rich supporting accessories.

1.2 Icom Plug (Icom Custom Plug)

Icom Plug is a proprietary dual-pin connector exclusive to Icom radios. It adopts the same 3.5mm+2.5mm pin combination visually, but it is a customized specification rather than a universal standard.

Designed for Icom’s professional and amateur radio devices, it adds exclusive structural and electrical optimizations for industrial-grade stability, with strict dimensional and protocol restrictions, resulting in poor universality.

2. Compatibility: Supported Radio Brands & Models

2.1 TK Plug Compatibility

As the universal civilian radio connector, TK Plug supports a wide range of mainstream brands, covering most entry-level and commercial handheld radios:

• Kenwood: All TK-series civilian handheld radios

• Baofeng: UV-5R, UV-82, BF-888S and most popular models

• Retevis, Hytera: Most commercial dual-pin handheld radios

• Other generic civilian two-way radios with standard 11mm dual-pin ports

2.2 Icom Plug Compatibility

Icom Plug is brand-exclusive, only adapted to Icom’s professional handheld and mobile radios, mainly including:

• Handheld Radios: Icom F series, IC-V8, IC-U82, IC-F3400, IC-F4000 series

• Professional Amateur Radios: Classic portable models for industrial and ham radio use

• Note: It is not compatible with Kenwood, Baofeng, or generic civilian radios

3. Application Scenarios: Which One to Choose?

Choose TK Plug if:

• You use civilian/commercial radios (Baofeng, Retevis, generic Kenwood models)

• You need cost-effective, versatile earpieces, PTT mics, or programming accessories

• Your scenarios are daily security, construction, team outdoor activities, and amateur radio daily use

• You pursue low-noise audio, stable professional communication, and accurate device programming

• Your scenarios are industrial communication, professional ham radio operation, and commercial high-precision communication

4. Common User Mistakes to Avoid

1. Judging compatibility by appearance only: Similar dual-pin shape does not mean interchangeable. Always confirm plug specification and pin spacing.

2. Forcing mismatched plug insertion: This will wear out the radio port, cause poor contact, and even burn the audio/PTT circuit in severe cases.

3. Blindly buying "universal" accessories: Most universal dual-pin accessories default to TK Plug, which cannot adapt to Icom professional radios.

Quick Tips

If you are unsure about your radio’s plug type, check the official device manual or measure the pin center distance: 11mm = TK Plug, 10.5mm = Icom Plug.
