43045-0602 6-Pin 3.0mm Header: Complete Specifications & Data Analysis

Industry surveys show a large share of wire-to-board designs migrate to 3.0 mm pitch when higher mechanical robustness and current capacity are required versus 2.54 mm alternatives; roughly one-in-three small-form connectors in industrial and appliance designs use 3.0 mm variants. This technical guide delivers a concise, actionable specification, verification, and sourcing guide for the 43045-0602 6-pin 3.0mm header.

Product Overview & Typical Applications

43045-0602 6-pin 3.0mm header technical view

What the 43045-0602 is

The 43045-0602 is a single-row, through-hole wire-to-board header in a fixed 6-pin configuration with a 3.0 mm pitch. It serves as a compact, robust interface for mating housings or crimp housings, optimized for scenarios where higher-current or superior mechanical retention is required compared to standard 2.54 mm headers.

Common Application Scenarios

  • Industrial Control: Power and sensor harnesses where vibration resistance and 1–3 A per pin are required.
  • Consumer Appliances: Modular assemblies requiring reliable mating and predictable pinouts.
  • Test Fixtures: Robust insertion/extraction cycles with clear pin labeling.

Complete Technical Specification

Mechanical Dimensions & Footprint

The key pitch is 3.00 mm; a 6-pin row yields a nominal overall row length near 15.00 mm (center-to-center). Recommended PCB footprint uses 1.0–1.2 mm diameter plated through-holes.

PCB Footprint, Mounting & Assembly Guidance

PCB Design Strategy

Use through-hole pad pairs sized per the drill table. Place supporting mechanical vias every 10–12 mm adjacent to the header to reduce flex. Define a 0.5–1.0 mm keepout area in the PCB CAD to avoid SMD components directly behind tail exits.

Soldering & Reflow

Typical lead-free reflow peak 235–245°C. For hand soldering, use a 350–370°C iron. Avoid prolonged heating to prevent insulator deformation. Ensure full wetting around the tail with a 0.2–0.6 mm fillet height.

Verification, Testing & Failure Modes

  • Continuity: Measure all pins; expect <40 mΩ per contact.
  • Mechanical: Verify mating cycles (100–1000 depending on plating).
  • Fatigue: Mitigate solder-joint fatigue with strain relief cable ties.
  • Wear: Use gold plating for high-cycle reliable mating requirements.

Summary

  • The 43045-0602 delivers a durable 3.0 mm pitch interface suitable for wire-to-board and low-voltage power applications.
  • Key parameters: 3.00 mm pitch, 1.0–1.2 mm drill size, 1–3 A per pin rating.
  • Always validate solder fillet quality and include keepout zones to reduce joint fatigue and misalignment risk before committing to mass production.

Common Questions (FAQ)

What is the recommended PCB footprint for the 43045-0602 6-pin 3.0mm header? +
The recommended footprint uses 1.0–1.2 mm plated through-holes with 1.8–2.2 mm annular pads and a center-to-center pitch of 3.00 mm. Maintain hole position tolerances of ±0.1 mm and include a 0.5 mm keepout from mating faces.
How to solder 3.0mm header reliably? +
Wave or selective soldering is preferred for through-hole versions. Ensure full wetting of tails with a 0.2–0.6 mm solder fillet. For hand-soldering, use a 350–370°C tip and work quickly to avoid overheating the insulator housing.
What testing should be done before production? +
Perform continuity and contact resistance checks (<40 mΩ target), insertion/withdrawal force tests, and thermal cycling to simulate field conditions. Use sample lots for dimensional verification and solderability testing prior to full-volume purchase.
