Pitch is only the first filter. It does not guarantee electrical capability, mating compatibility or footprint interchangeability. Select the full connector system and apply the manufacturer’s derating data.

Selection note: Current, temperature, wire range and mating-cycle figures are system-specific. Confirm the exact housing, terminal, header, wire and derating conditions in the manufacturer data sheet before release.

Selection rule: Do not specify a retention force from a generic table. Obtain it from the exact mating pair’s data sheet and validate the completed harness under the required vibration, pull and thermal conditions.

Engineering note: Per-circuit current is not a blanket connector-family value. It depends on the selected terminal, wire gauge, circuit count, temperature rise and application derating.

Important: “JST-style” is not a specification. Choose the housing, terminal and header from the same approved JST series, then confirm the exact wire range and derating in the applicable data sheet.

Migration rule: A 2.54 mm prototype header cannot be exchanged for a JST or Molex connector without a PCB and harness change. Verify footprint, header orientation, keying, terminal and cable assembly together.

Do not use the numeric crimp-height examples in this article as production release limits. The correct height, pull requirement and visual criteria come from the selected terminal’s manufacturer drawing and the approved applicator setup.
