1. What Is the Hirose DF19 Series Connector?
The Hirose DF19 Series is a 1.0 mm pitch, low-profile wire-to-board connector family.
It is primarily designed for signal connections between PCBs and cables, featuring a low-profile design, compact dimensions, and multiple mounting configurations.
The DF19 Series features a metal shell structure that can provide a grounding connection through the housing, helping improve electromagnetic interference (EMI) protection around the connector interface.
Key Features of the DF19 Series
- 1.0 mm contact pitch
- 8-pin, 14-pin, 20-pin, and 30-pin configurations
- Low-profile connector design
- Supports Micro Coaxial Cable
- Supports Discrete Wire connections
- Supports FPC flat cables
- Top-board, offset, and reverse-offset mounting configurations
- Right-angle PCB mounting
- Metal-shell versions available for EMI protection
- Supports SMT and crimp termination methods
- Suitable for LCD displays and compact electronic equipment
Different DF19 models have different mounting heights and termination structures. Always verify the complete part number during connector selection rather than choosing a connector based solely on its pin count.
2. Hirose DF19 Series Connector Types and Part Numbers
The DF19 Series can primarily be classified into the following types according to their PCB header mounting configurations:
- DF19G: Top-board mounted pin headers.

3. DF19 Series Micro Coaxial Cable Assemblies
The DF19 Series can be used for micro coaxial cable assembly manufacturing, but different termination configurations must be carefully distinguished.
Hirose documentation lists Micro Coaxial Cable as one of the compatible cable types for the DF19 Series. Official product documentation also includes micro coaxial cable-related models such as DF19-20P-1V(52).
However, the official product status of DF19-20P-1V(52) indicates that it is not recommended for new designs. For new projects, its current availability and possible replacement options should be verified first.
Micro Coaxial Cable Assembly Structure
A typical micro coaxial cable assembly consists of the following components:
- DF19 cable-side connector
- Micro coaxial cable
- Center conductor
- Dielectric insulation
- Outer shielding layer
- Metal grounding structure
Unlike conventional discrete wires, micro coaxial cables feature an individual center conductor and an outer shielding structure.
During manufacturing, special attention must be paid to center conductor termination, outer conductor termination, insulation spacing, and shield grounding connections.
Micro Coaxial Cable Specifications
For DF19 micro coaxial cable projects, cable compatibility must be confirmed according to the specific connector part number.
The official product documentation lists 40 AWG among the relevant micro coaxial cable termination specifications.
Not all DF19 connectors should automatically be considered compatible with 40 AWG micro coaxial cables. The corresponding product drawings and crimping specifications must be checked before manufacturing.
4. DF19 Series Discrete Wire Cable Assemblies
In addition to micro coaxial cables, the DF19 Series also supports Discrete Wire cable harness manufacturing.
This configuration typically uses multiple individually insulated wires connected to cable-side DF19 sockets through DF19A crimp contacts.
Common DF19 wire gauge options include:
| Crimp Contact Part Number | Compatible Wire Gauge | Conductor Construction |
|---|---|---|
| DF19A-2830SCFA | 28 AWG / 30 AWG | Stranded tinned copper wire |
| DF19A-3032SCFA | 30 AWG / 32 AWG | Stranded tinned copper wire |
Recommended wire specifications include:
| AWG | Conductor Construction | Cross-Sectional Area | Insulated Wire Outer Diameter |
|---|---|---|---|
| 28 AWG | 7/0.127 mm | 0.089 mm² | 0.5–0.6 mm |
| 30 AWG | 7/0.1 mm | 0.055 mm² | 0.5–0.6 mm |
| 32 AWG | 7/0.08 mm | 0.035 mm² | Verify according to the applicable crimp specifications |
DF19 discrete wire harnesses are suitable for LCD control cables, display module wiring, camera modules, and internal connections in compact electronic equipment.
5. DF19 Series Crimp Contacts and Grounding Accessories
In addition to the cable-side sockets, DF19 cable assemblies require compatible crimp contacts.
DF19A Crimp Contacts
Major models include:
- DF19A-2830SCFA
- DF19A-3032SCFA
The part number designations indicate:
- 2830 corresponds to 28–30 AWG.
- 3032 corresponds to 30–32 AWG.
- SCF indicates a tape-and-reel Socket Contact.
- A indicates the gold-plated version.
Hirose also provides different packaging suffixes, such as (41), to identify specific packaging configurations.
DF19GND Grounding Accessories
The DF19 Series provides grounding accessories for FPC and micro coaxial cable connections.
Related part numbers include:
- DF19G-14S-1F-GND(06)
