Q1: What is the relationship between Mfr. # 6099-0610 and Part Name US120A02MA-B3?

6099-0610 is the standard Manufacturer Part Number (Mfr. #), while US120A02MA-B3 is the factory part name / internal technical designation assigned by Sumitomo Electric Wiring Systems (SEWS) on the official package label.

Q2: What resin material is used for the 6099-0610 housing, and how is it verified?

The housing is molded from automotive-grade PBT (Polybutylene Terephthalate) thermoplastic. Material authenticity can be verified via the molded resin code PBT explicitly stamped onto the side of the housing structure.

Q3: What is the purpose of the white clip component integrated into the 6099-0610 housing?

The white component serves as a Terminal Position Assurance (TPA) lock. Once crimped terminals are inserted into the housing cavities, pushing the TPA into its final locked position ensures full contact retention and prevents pin disconnection caused by cable tension or vehicle vibration.
