2.0mm Female Headers and PCB Socket Strips

2.0mm Female Headers and PCB Socket Strips

This collection covers compact 2.0mm-pitch female headers for board-to-board and PCB interconnects. Its core socket range includes single- and dual-row layouts, vertical and right-angle through-hole formats, surface-mount versions, side-entry sockets, and multiple body heights. Several listings mix female sockets with male headers, IDC box headers, jumper caps or crimp housings, so select by the exact variant rather than the product title alone.

Female Header Formats in the Range

• Single-row straight through-hole sockets, including PH4.3 and PH6.35 body-height options
• Single-row low-profile SMT sockets in selected position counts
• Dual-row vertical through-hole sockets in PH2.0, PH4.3 and PH6.35 formats
• Dual-row right-angle and side-entry sockets for horizontal mating
• Dual-row SMT sockets and mixed straight, right-angle and SMT listings
• Round-hole 2.0mm female socket-strip options within a mixed 2.0mm/2.54mm listing

How to Select a 2.0mm Female Header

1. Confirm the 2.0mm contact pitch and, for dual-row parts, the row spacing.
2. Choose single row (1×N) or dual row (2×N). A 2×10 part has 20 total contacts.
3. Select the female variant on listings that also contain male headers.
4. Match straight through-hole, right-angle, side-entry or SMT mounting to the PCB footprint.
5. Check body height, mating depth, contact-entry direction, tail length and board clearance.
6. Verify the mating header’s post dimensions and required insertion depth.
7. Confirm package quantity and whether the selected option is a full strip or a fixed position count.

Body Height and Entry Direction

PH2.0, PH4.3, PH6.35 and PH7.2 labels in these listings describe different physical formats, not interchangeable performance grades. Body height changes stack height and contact engagement. Straight sockets normally mate perpendicular to the PCB, while right-angle and side-entry formats mate parallel to it. Compare drawings and PCB land patterns before substituting one style for another.

Standard Contacts vs. Round-Hole Sockets

Standard female headers and round-hole socket strips may share 2.0mm pitch but can differ in accepted pin shape, pin size, insertion depth and PCB footprint. A round-hole option should not be assumed to accept every square-post header or component lead.

Products That Are Not Female Headers

The collection also contains dedicated male pin-header listings, a mixed-pitch IDC box-header listing, a 2.0mm jumper cap and a double-row crimp housing listing. The crimp housings require suitable terminals and a matching PCB header; they are not PCB-mounted female header strips. IDC box headers, jumper caps and male breakaway strips must be evaluated under their own selected options.

Compatibility Boundaries

Matching 2.0mm pitch and contact count does not prove mechanical or electrical compatibility. Verify row spacing, post cross-section, shrouding, polarization, entry direction, mating depth and pinout. IDC, JTAG and ISP search terms in a mixed listing do not establish a standard debug-interface pin assignment.

Electrical, Material and Compliance Limits

The source listings contain differing or incomplete claims for current, voltage, contact resistance, temperature, contact material, plating and compliance. Values such as 3A, 1000V, gold plating, UL94V-0, CE or RoHS are not established for every item or variant in this collection. Use the specifications for the exact selected part and validate samples under the intended contact loading, PCB process and operating conditions.

Frequently Asked Questions

Will a 2.0mm female header mate with a 2.54mm header?
No. The pitch differs, and the mechanical dimensions must match.

Are all 19 listings female headers?
No. Some are male headers or mixed-format listings, and the collection also includes an IDC header, jumper cap and crimp housings.

Can a 1×40 or 2×40 strip be cut to size?
Some listings describe breakable strips, but cutting suitability depends on that product’s construction. Fixed-position molded sockets should not be assumed cuttable.

Are PH4.3 and PH6.35 versions interchangeable?
Not automatically. They differ in body height and may change stack height, mating engagement and clearance.

Does 2×20 mean 20 contacts?
No. It means two rows of 20, for 40 total contacts.

Are these automatically compatible with JTAG or ISP?
No. Confirm the connector layout, keying and signal pinout for the target interface.

Ordering Checklist

Confirm pitch, row spacing, row count, positions per row, total contacts, female selection, mounting style, entry direction, body height, PCB footprint, mating-post geometry, package quantity and part-specific electrical requirements.
