Overview
The A-BL127-DG-Z50MP1 is a 50-position female header receptacle connector manufactured by ASSMANN WSW Components. It features a bottom entry design with a 2.54 mm (0.1 inch) pin spacing and a single row configuration. The insulator material is PA6T+30%GF, rated UL94V-0 in black. Contacts are gold-plated brass sockets designed for surface mount termination.
Feature Summary
- Bottom entry receptacle design for PCB integration
- Gold-plated brass contacts for reliable signal transmission
- High-temperature resistant PA6T+30%GF insulator housing
Applications
- Industrial control system interconnects
- Consumer electronics board-to-board connections

Procurement Notes
Verify the specific contact plating thickness and operating temperature range against the official manufacturer datasheet before procurement. Ensure the selected variant matches the required current rating and insulation resistance specifications for the target application environment to guarantee long-term reliability.
Selection Notes
Select this component when a low-profile, surface-mountable female header with bottom entry is required. The 2.54 mm pitch suits standard digital and power signals. Verify that the PCB footprint aligns with the manufacturer's recommended land pattern to ensure proper solder joint integrity during assembly.
Part Context
This part belongs to the A-BL127 series of rectangular connectors from ASSMANN WSW. The series offers various pin counts and configurations, utilizing robust thermoplastic materials suitable for automated surface mount manufacturing processes in high-volume electronic assemblies.
Replacement Considerations
Direct substitutes include other 50-pin, 2.54mm pitch, bottom-entry female headers from manufacturers such as Samtec or Molex. Verify mechanical dimensions, terminal plating, and thermal ratings before substitution.
