AF125 Germanium RF Transistor – Reliable Vintage Radio Restoration

The AF125 is a shielded PNP germanium RF transistor, electrically equivalent to the AF115 but manufactured to eliminate tin whisker growth. Highly prized by vintage radio enthusiasts and repair technicians for restoring classic 1960s and 1950s receiver stages.

Functions & Applications

Shielded 4-Lead Design: Integrated shield pin eliminates RF interference in sensitive radio circuits.
No Tin Whiskers: Superior reliability compared to AF115, preventing internal shorts in vintage equipment.
Germanium RF Performance: Excellent noise figure and stability in VHF/HF reception stages.
Direct AF115 Equivalent: Same electrical characteristics, purpose-built for 1960s–1950s radio restoration.

Frequently Asked Questions

Q: Will the AF125 drop directly into an AF115 socket?
A: The AF125 is electrically equivalent but physically smaller (TO-72). You may need to carefully bend the leads or use an adapter board to match the original AF115 hole spacing on vintage PCBs.

Q: What is the complementary NPN part for AF125?
A: The complementary NPN germanium RF transistor is the AF126.

Notes

Vintage NOS (New Old Stock) or used stock. Germanium transistors are sensitive to handling; avoid excessive heat during soldering. Tin whisker-free manufacture.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
