This is a Board to Cable/Wire style header — it mates with a corresponding MTA-156 receptacle housing that accepts crimp terminals. The square pin shape provides good solder fillet formation.
The part is obsolete; engineers and buyers need a drop-in or functional alternative to continue production or repairs.
Sourcing buyers must know availability to decide whether to purchase remaining inventory or switch to a replacement.
Design engineers need full specs (pinout, dimensions, ratings) to validate fit in their application.
Maintenance techs replacing a failed unit must ensure the header matches the existing wiring and footprint.
Buyers need to know if this part can be used interchangeably with similar shrouded headers from TE or other brands.
Brokers and supply chain planners assess obsolescence risk and plan for long-term availability or substitutes.
