Key Features
- 80-pin 0.8 mm pitch QFP80 SMT socket with gold-plated bellowed contacts provides secure, low-resistance IC seating for prototype and test applications
- Bellowed contact style absorbs lead co-planarity variation, reducing insertion force while maintaining reliable 0.5 A per-pin current capacity
- 20×20 contact configuration on a compact 0.787 × 0.551-inch SMT body enables drop-in QFP80 swapping without PCB rework
Applications
The IC149-080-012-B5 is designed for SMT prototyping boards and programming fixtures that need to evaluate or program multiple QFP80 ICs without soldering directly to the PCB. Engineers use it to accelerate firmware iteration on 80-pin microcontrollers and DSPs by swapping devices in seconds. It is also used in production test jigs where each IC must be inserted and removed hundreds of times without damaging the host PCB.

Frequently Asked Questions
What package type and pin count does IC149-080-012-B5 support, and what is the contact pitch?
The IC149-080-012-B5 is designed for QFP80 packages with 80 pins arranged in a 20×20 contact configuration at 0.8 mm pitch, fitting standard 80-pin quad flat pack ICs commonly used in microcontrollers and digital signal processors.
How does the bellowed contact style in IC149-080-012-B5 improve prototyping reliability compared with standard spring-pin sockets?
The bellowed contact style in IC149-080-012-B5 accommodates lead co-planarity variations of typical QFP80 packages, ensuring all 80 pins make consistent electrical contact even if leads are slightly bent or uneven, maintaining each contact's 0.5 A current rating without requiring perfect lead alignment.
For which design iteration or programming workflow is IC149-080-012-B5 most cost-effective compared to soldering QFP80 ICs directly?
IC149-080-012-B5 is most cost-effective when developers need to test 5 or more firmware revisions on 80-pin QFP microcontrollers, since each solder-desolder cycle risks damaging 0.8 mm pitch pads on the host PCB, and the socket allows unlimited device swaps while protecting a single prototype board investment.
