Q1: Is the 2005020271 compatible with standard USCAR automotive interfaces?

A: Yes, the stAK50h series is designed and tested to meet USCAR-2 standards. The 2005020271 specifically provides the high-density signal requirements typical in modern global automotive platforms.

Q2: What are the advantages of the SPS material used in the housing?

A: SPS (Syndiotactic Polystyrene) is chosen for its excellent chemical resistance and low moisture absorption. Unlike some other plastics, it maintains high dimensional stability after wave soldering, ensuring the 27 pins remain perfectly aligned for mating.

Q3: Does this header require specific mating receptacles?

A: Yes, this header must be paired with the corresponding stAK50h 27-circuit female receptacle housings. To ensure proper keying and latching, always verify the “Keying Option” (this model is a standard configuration) before purchase.
