When designing a PCB or selecting components for a production build, pin headers might look simple—but choosing the wrong one can lead to assembly issues, unstable connections, or costly redesigns.
At Easychips Precision, we support a wide range of interconnect solutions including Pin Headers, Female Headers, Board-to-Board and Wire-to-Board connectors, as shown on our product categories.
Here's a fast and practical guide to help engineers and buyers quickly choose the right pin header.
1) Start with Pitch (Spacing)
The pitch is the distance between pins—this is the first filter in selection.
Typical pitches include:
1.27mm (compact designs)
2.00mm (space-saving)
2.54mm (most common / standard)
2) Decide: Single Row or Double Row
Pin headers usually come in:
Single-row (1×N) — most common, easy routing
Double-row (2×N) — higher density, more signals in limited space
3) Select Orientation: Straight or Right Angle
Depending on product structure and cable direction:
Straight (Vertical) — best for stacking or top access
Right-angle — best for side entry, compact enclosure fit
4) Choose Pin Length & Mounting Type
Pin headers can be:
Through-hole (strong mechanical retention)
SMT (Surface Mount) (compact, automation-friendly)
5) Consider Plating: Tin vs Gold
This affects both performance and cost:
Tin plating: cost-effective, good for general use
Gold plating: better for low resistance, corrosion resistance, frequent mating/unmating
6) Environment & Application Check
If your product will be used in:
industrial automation
LED lighting
smart home
vehicle electronics
communication equipment
You may need stronger materials and stable contact design. Easychips also provides interconnect solutions across these application areas.
7) If You Need Compatibility—Use Replacement Models
Many buyers need pin-to-pin replacement options that match existing brands.
Easychips specifically highlights “Connector Replacement Solutions”, offering compatibility and substitutability with multiple global brands—ideal for projects requiring drop-in replacements. easychipsconnector.com
Final Tip: The Fastest Selection Method
If you want to shortlist within minutes, prepare these 5 parameters:
Pitch
Row count (1×N / 2×N)
Orientation (straight / right angle)
Mounting (TH / SMT)
Plating (tin / gold)
Send them to your supplier, and you can get accurate recommendations + drawings quickly.
