Part-numbering & Family Context
Part numbers in this family encode position count, plating, and orientation; the 0700 suffix identifies the seven-position header. Closely related variants span 3–7 positions and include vertical and right-angle orientations. For alternatives, prioritize matching pitch (2.00 mm) and row count before comparing plating and housing materials.
Deep Dive: Electrical & Mechanical Specs
Electrical Specifications
Confirm contact resistance, insulation resistance, and rated current per circuit. Typical acceptance criteria involve:
- Milliohm-level contact resistance after mating cycles.
- Dielectric tests at specified AC or DC voltages.
- Current derating assessment at elevated ambient temperatures.
Mechanical & Dimensional
Critical data for PCB design includes:
- Recommended land pattern and solder mask keep-out zones.
- Pin center tolerances to prevent tombstoning.
- Mating durability and maximum lead-free reflow temperature limits.
Variants, Packaging & Ordering Info
Common Variants
Variants alter plating (gold vs. tin) and orientation. Gold improves low-voltage reliability, while tin is cost-effective for general purpose. Vertical vs. right-angle choices change the PCB footprint and mechanical loading profiles.
Packaging Details
Supplied in tape-and-reel for automated SMT pick-and-place or trays for manual assembly. For high-volume lines, confirm leader/trailer specs and pick positions to ensure seamless production integration.
Typical Applications & Design Considerations
Note: Evaluate conformal coating and cleaning compatibility with polyamide (PA) housings and tin contacts during the design phase.
Selection, Testing & PCB Assembly Checklist
Pre-purchase Selection
- Mating connector compatibility check
- Pitch and PCB footprint verification
- Rated current vs. application demand
- Lifecycle and supplier availability
- Exact numeric specs from official datasheet
Assembly Validation & QA
- Stencil design and aperture verification
- Reflow profile validation (Lead-free)
