A three-step method to check structure, compatibility and application requirements.
July 12, 2026
Start connector selection by confirming that the housing, terminal and pin header belong to the same compatible series. Do not rely on appearance or a similar part number alone.
Three selection steps
Check the structure: verify mating direction, polarization, latching and keying.
Check compatibility: confirm positions, layout, pitch and series compatibility between housings, terminals and pin headers.
Check the application: confirm wire size, electrical requirements, temperature, vibration, humidity and whether sealing or secondary locking is required.
Please provide the current part number, clear photos, number of positions, wire size, operating environment and expected quantity. Harness drawings or connector-interface drawings help speed up matching.
