SMT Quad, PLCC, QFN & QFP to DIP Adapters
Adapt quad-style and leaded SMT devices to DIP through-hole footprints for replacement, test, and production support.
Overview
SMT Quad, PLCC, QFN, and QFP to DIP adapters allow a range of quad-style surface-mount devices to be installed into DIP through-hole footprints commonly found in legacy systems, test fixtures, and production replacement applications. These adapters provide a mechanical and electrical interface between SMT device land patterns and DIP-based layouts.
Adapters in this category include device-specific mappings (such as 8051-mapped PLCC devices) as well as signal-based and pin-based wiring options, depending on the package type and application. Solutions are available in prototype quantities as well as high-volume production builds, with turnkey options available where the device can be sourced and permanently attached to the adapter.
How to Select Your Adapter
- Package type — PLCC, QFN, or QFP
- Pin / land pattern count — must match the device package
- Wiring requirement — device-specific mapping, 1:1 by signal, or 1:1 by pin
- Target footprint — 600 mil DIP span
- Application context — replacement, test, or production build
If the device requires a custom pin mapping or does not align with standard package definitions, provide the package drawing for engineering review.

Not Finding What You Need?
If your quad-style SMT device requires a custom pin mapping, non-standard package support, or a configuration not shown, custom solutions are available. Provide the device package drawing and application details, and an engineer will review the requirements and recommend an existing option or define a custom adapter.
