The natural-color housing alternative 171825-4 shares identical electrical ratings and dimensions — the difference is insulation color (black vs natural), not fit or function. ## Active production with ROHS3 compliance","metaTitle":"2-171825-4 TE Connectivity EI Header 4 Pos 2.5mm","metaDescription":"2-171825-4 TE Connectivity AMP Connectors EI series header, 4 positions, 2.50mm pitch, through hole, shrouded with latch.
