44-pin QFP ZIF socket adapter with open-top socket for 0.80 mm pitch QFP devices

Overview

The primary purpose of this hub page is to help customers identify an existing QFN-to-QFN adapter or engage Adapters-Plus engineering to design a custom solution when standard products are not available.

About QFN to QFN Adapters

QFN-to-QFN adapters provide a ZIF Socket to enable easy and repeated testing of your Quad Flat No-Lead (QFN) on your production footprint. These adapters are essential for testing, debugging, and development, enabling easy swapping of QFN-packaged ICs without soldering. Ideal for engineers working with QFN footprints, these adapters support rapid prototyping and evaluation.

How to Navigate

  • By Pin Count – Choose an adapter that matches the QFN device, pitch, and body dimensions.
  • By Device Type – QFN to QFN Adapters are available in 8, 16, 20, 24, 28, 32, 40, 44, 48, and 64 pin counts.
  • View in Grid or Rows – Select your preferred display format for easier browsing.

Contact us for expert guidance if you’re unsure which adapter suits your needs.

How to Choose the Correct Adapter

Match the adapter to your QFN pin count, lead pitch, and IC body size.

If you do not see an exact match in the table below, submit a request and we can design a custom solution around your footprint and mechanical constraints.
