Technical Guide
Deutsch connector part numbers identify the connector family, housing type, cavity count, contact configuration and compatible components. Understanding part numbers such as DT04-2P, DT06-2S, W2P, W2S, 0462 and 0460 helps you choose the correct housing, contacts, wedgelocks and mating connector.
Many engineers, harness builders, technicians and procurement teams know which Deutsch connector they need, but not always what the part number means. Learning the structure makes it easier to confirm compatibility, reduce ordering mistakes and service existing wiring harnesses.
This guide explains how to decode common Deutsch connector part numbers, including DT04-2P, DT06-2S, W2P, W2S and common Deutsch contact numbers.
Quick Answer: How Do You Read a Deutsch Connector Part Number?
To read a Deutsch connector part number, start with the family code, then identify the housing type, cavity count and contact configuration. For example, DT04-2P means DT Series, receptacle housing, 2 positions and pin contact configuration.
| Part number section | Meaning | What it tells you |
|---|---|---|
| DT | Connector family | Deutsch DT Series. |
| 04 | Housing type | Receptacle housing. |
| 2 | Cavity count | 2-way / 2-position connector. |

Anatomy of a Deutsch Connector Part Number
Many Deutsch connector housing part numbers follow a readable structure. Once you know the pattern, part numbers become a fast way to identify connector family, housing side, position count and contact configuration.
| Code position | Example | Meaning | Selection note |
|---|---|---|---|
| Family code | DT | Connector family. | Match all parts to the same family. |
| Housing code | 04 or 06 | Receptacle or plug housing. | Pair compatible plug and receptacle sides. |
| Cavity count | 2, 3, 4, 6, 8 or 12 | Number of positions or circuits. | Match cavity count on both halves. |
| Contact configuration | P or S | Pin or socket contact configuration. | Confirm pin/socket pairing before ordering contacts. |
Connector Family Codes
The family code tells you which Deutsch connector system the part belongs to. This is the first compatibility check because DT, DTM and DTP components should not be mixed.
| Family code | Connector family | Typical use | Shop |
|---|---|---|---|
| DT | DT Series | Lighting, relays, solenoids and general-purpose wiring. | Shop DT |
| DTM | DTM Series | Sensors, switches, CAN bus and compact signal wiring. | Shop DTM |

Understanding W2P and W2S Wedgelocks
Wedgelocks provide secondary contact retention and help keep contacts aligned inside the connector housing. The wedgelock part number must match the connector family, housing side and cavity count.
| Wedgelock | Used with | Meaning | Shop |
|---|---|---|---|
| W2P | DT04-2P | 2-way receptacle-side wedgelock for pin configuration. | Shop W2P |
| W2S | DT06-2S | 2-way plug-side wedgelock for socket configuration. | Shop W2S |
If the wedgelock will not seat, do not force it. Read Deutsch Connector Not Locking? for troubleshooting support.
Understanding Deutsch Contact Part Numbers
Deutsch contact part numbers such as 0462-201-16141 and 0460-202-16141 are contacts, not connector housings. Contacts must match the connector family, contact size, wire gauge and pin or socket side.
| Contact code | Typical role | Selection note | Shop |
|---|---|---|---|
| 0462 | Pin contacts. | Match by connector family, contact size and wire gauge. | Search 0462 contacts |
| 0460 | Socket contacts. | Match to the mating pin contact and housing family. | Search 0460 contacts |

Part Number Compatibility Checklist
Before ordering a Deutsch connector by part number, check the full assembly. A housing alone may not include the mating half, contacts, wedgelocks or tools.
| Checklist item | What to confirm | Shop or guide |
|---|---|---|
| Connector family | DT, DTM or DTP matches the application. | Shop connectors |
| Housing side | 04 receptacle or 06 plug is the correct side. | DT04 vs DT06 guide |
| Cavity count | Both connector halves have the same number of positions. | Mating guide |
| Contact side | Pin and socket contacts are paired correctly. | Shop contacts |
| Wedgelock | Wedgelock matches the housing side and cavity count. | Shop wedgelocks |
| Tools | Crimp and removal tools match the contact type. | Shop tools |
Common Part Number Mistakes
Most Deutsch connector part number mistakes happen when users recognize part of a code but miss the family, cavity count, pin/socket configuration or included components.
| Mistake | Why it causes problems | Better practice |
|---|---|---|
| Confusing DT04 and DT06 | They are different housing sides and are not interchangeable. | Use DT04 as the receptacle side and DT06 as the mating plug side. |
| Ordering pins instead of sockets | Pin and socket contacts serve different sides of the connector pair. | Confirm P and S configuration before ordering contacts. |
| Ignoring cavity count | A 2-way connector will not mate with a 4-way connector. | Match cavity count across both mating halves. |
| Assuming contacts are included | Some housings are sold without contacts or wedgelocks. | Check the product listing and complete assembly requirements. |
| Mixing DT, DTM and DTP parts | Different families use different housings, contacts and wedgelocks. | Keep all parts within the same connector family. |
