Product details

Board Fit and Signal Count

The 5-534978-3: The dual-row layout packs 20 circuits into a compact board footprint — the row spacing is also 0.100 inch, so the pin field is 2 rows × 10 positions per row.

Current and Contact Interface

Each contact is rated 3 A at 250 VAC. The gold mating finish — 30 µinch over nickel — gives this header a rated mating cycle life well into the hundreds, making it a good fit for equipment that sees regular reconnects in the field. The post finish is tin, which solders cleanly into the plated through-hole.

Frequently asked questions

Where can I buy 5-534978-3 and what is the lead time?
