QSOP to DIP Programming Adapters
QSOP to 0.100″ DIP programming adapters.
Technical Overview
QSOP to DIP programming adapters provide an electrical and mechanical interface between fine-pitch QSOP (Quarter Small Outline Package) devices and standard 0.100″ pitch DIP programming sockets.
The top interface consists of a QSOP socket defined by 0.635 mm lead pitch, body width, and total pin count. The bottom interface presents a DIP plug configured for the required pin count and row spacing (commonly 0.300″ or 0.600″).
Routing may be configured as direct 1:1 mapping or as device-specific pin reassignment when required by the programming system. Any skips, shorts, or remapping are implemented strictly per device definition.
- Package pitch: 0.635 mm (0.025″)
- Common pin counts: 8–28+ pins
- DIP pitch: 0.100″ (2.54 mm)
- DIP row spacing: 0.300″ or 0.600″
Mechanical Configuration
QSOP to DIP programming adapters are defined by the mechanical dimensions of the QSOP package and the required DIP footprint. Proper fit depends on accurate package body width, lead span, pitch, and coplanarity.
- Top Interface (QSOP): 0.635 mm pitch, defined body width, lead span, and total pin count.
- Socket Type: Open-top, LIF, or clamshell configurations depending on insertion frequency and pin count.
- Orientation: Pin-1 reference and silkscreen alignment to prevent rotation errors.
- Bottom Interface (DIP): 0.100″ pitch plug with specified pin count and row spacing (0.300″ or 0.600″).
- Pin Style: Square post or machine pin based on mating socket requirements.
- Assembly Height: Overall height and actuator clearance must match the programming socket or fixture.
Provide the IC mechanical drawing with package dimensions and tolerances to ensure correct socket selection and fit.
Routing Configurations
All QSOP to DIP programming adapters listed in this catalog utilize direct 1:1 pin mapping.
- 1:1 Mapping: QSOP pin numbers correspond directly to the matching DIP pin numbers.
- No signal reassignment, skips, or shorts are implemented.
- Power and ground pins maintain their native device numbering.
If a device-specific DIP pinout is required by your programming system, provide the target device reference for review.

Not Finding What You Need?
If your required QSOP package or DIP configuration is not listed, a custom adapter can be defined based on your device and programming system requirements.
- Provide the IC mechanical drawing (body width, pitch, lead span, pin count).
- Specify the required DIP format (pin count and row spacing).
- Identify the programming system or required DIP pinout reference.
- Confirm whether routing is 1:1 or device-specific.
Complete mechanical and electrical definition ensures correct fit and routing.
