The natural (white) thermoplastic, glass-filled housing is UL94 V-0 rated. ## Peer Comparison: 1-292164-1 vs 640445-9 The 1-292164-1 is a different connector entirely — it is an 11-position, 2.00mm pitch header from the CT series, with a 4-wall shroud and a detent lock. The 640445-9 runs at 3.96mm pitch and carries a friction lock. These are not form-fit-function equivalents: the pitch and position count differ, so a board spin would be required to swap.","metaTitle":"640445-9 TE Connectivity MTA-156 Header 9 Pos 3.96mm Pitch","metaDescription":"640445-9 TE Connectivity AMP Connectors MTA-156 header, 9 positions, 0.156\" (3.96mm) pitch, shrouded-1 wall, friction lock.
