DT, DTM and DTP Connectors: How to Choose

DT, DTM and DTP are commonly used series names when shopping for wiring connectors. Start with the series and part number specified for your equipment, then check the individual housing, contact and seal requirements before ordering. Similar names or the same number of positions do not establish that two parts will mate.

1. Identify the connector you need

Check the part number on the housing or the equipment documentation. Note the number of positions, the plug or receptacle form, the contact type and any keying, colour or mounting features. Compare the dimensions and mating details with the relevant product information. If a marking is unclear, send a clear photograph and the application details to our sales team before ordering.

2. Check the wire and contact requirements

For each circuit, identify the wire size, expected operating conditions and electrical requirements. Select contacts and a crimping method specified for the actual connector and wire. A housing and terminal sold in the same broad series are not automatically a verified match; use the product information or ask us to confirm the exact part combination.

3. Compare the available product forms

  • Housing: check whether the listing includes contacts, seals and any secondary locks, or whether these are sold separately.
  • Loose terminals: confirm the contact type, the relevant housing and the supported wire range in the product information.
  • Pre-wired connector: check the selected end, number of positions, wire length and what is included. Wire colours can vary by batch as described on the product page.

4. Confirm the order quantity

Read the selected product option: a single connector is not necessarily a mating pair, and a quantity option can represent several pieces of the same selected item. Review the item description and images to identify what will be delivered.

Reference and important distinction

TE Connectivity’s DEUTSCH product catalog describes its own DT, DTM and DTP families and contact systems. Use its specifications only for the products to which they apply. CNCOW listings must be evaluated by their own descriptions and verified specifications; the catalog link does not establish manufacturer origin, authorization, interchangeability or a rating for a CNCOW product.
