Product details

38-Position Board-to-Board Receptacle, 2.00mm Pitch

The 55508-138: The 2.00mm pitch and 0.079" row spacing set the PCB footprint for a compact, high-density interconnect. Applications include general-purpose, industrial, and medical equipment.

Available through independent distribution channels. Sourced per your BOM quantity against a quote.

The 0.091" (2.30mm) insulation height and dual-row layout require a matching header with a compatible stack height. Confirm the header's mated height against your board-to-board spacing budget before ordering.

Contact Finish and Reliability

Mating contacts are gold over phosphor bronze with 30.0µin gold thickness — this is a robust plating grade for applications requiring hundreds of mating cycles. For lead-free soldering requirements, a tin-plated post variant (if available in the series) would be needed — this specific order code carries tin-lead on the termination side.

Frequently asked questions

Where can I buy 55508-138 and how do I get a price?

55508-138 is obsolete from the manufacturer but available through independent distribution. No stock-holding or price figure is listed here.

What is the mating connector for 55508-138?

It mates with a 2.00mm pitch pin header (male) from the same Minitek® 2.00mm series. The specific mating header part number depends on the required stack height and position count.

Is there a lead-free version of 55508-138?

This specific order code has tin-lead plating on the solder posts. A lead-free version would require a different order code within the Minitek® 2.00mm series with tin or gold post finish — confirm with the manufacturer's product listing.
