Overview
The A-BL127DG48-021-GSR1 is a rectangular connector receptacle manufactured by Assmann WSW Components. It features a 48-position configuration with a 0.050-inch (1.27mm) contact pitch. The component is designed for surface mount technology (SMT) applications, ensuring secure attachment to printed circuit boards. The contacts are finished with gold plating to provide reliable electrical conductivity and corrosion resistance. This specific part number denotes the 48-pin variant within the BL127 series.
Feature Summary
- Surface mount receptacle design for PCB integration
- Gold-plated contacts for enhanced signal integrity
- Standard 1.27mm pitch spacing
Applications
- General electronic interconnects
- Industrial control systems
- Consumer electronics assemblies
Procurement Notes
Verify the exact suffix GSR1 against the manufacturer's current datasheet to confirm reel packaging specifications and tape dimensions. Ensure the 48-position requirement matches the target board footprint. Cross-reference the pinout diagram with the system schematic to prevent orientation errors during assembly.
Selection Notes
Select this component when a 48-channel interface is required in a compact surface-mount form factor. The 1.27mm pitch offers a balance between density and manufacturability. Consider the gold finish if long-term reliability in oxidizing environments is critical compared to tin alternatives.
Part Context
This part belongs to the BL127 series of rectangular connectors from Assmann WSW Components. The series provides various position counts, including 20, 48, and 76 positions, sharing common mechanical and electrical characteristics. The model indicates a standard receptacle configuration suitable for mating with corresponding header pins.
Replacement Considerations
Direct substitutes include other 48-position 1.27mm SMT receptacles from manufacturers such as Samtec or Molex, provided the mechanical footprint and contact plating requirements are identical. Verify that any alternative part supports the same peak reflow temperature profile.
