Product Overview
The XUNPU WAFER-XH2.54-2PLB is a two-position vertical surface-mount wafer/header connector in the manufacturer’s XH2.54 family. XUNPU lists the family as a vertical board-mounted SMD pin-header product and identifies the exact WAFER-XH2.54-2PLB row as In Production.
For electrical selection, the manufacturer page specifies a 1 A rated current, 125 V rated voltage, 500 V AC dielectric withstand, 100 MΩ minimum insulation resistance, and 20 mΩ maximum contact resistance.

Application Fit
This is a low-complexity interconnect part, so its selection is mainly mechanical and electrical rather than feature-driven. It can be considered for internal wire-to-board connections in consumer, appliance, communication, control, and other electronic assemblies when the mating system, board footprint, current, voltage, and environmental requirements match the exact connector system.
XUNPU’s family page names a wide range of market sectors, including regulated and high-reliability fields. Those broad manufacturer application labels do not establish military, aerospace, automotive, medical, or safety qualification for this exact part. Any such requirement must be verified separately from formal manufacturer qualification documentation.
Why Choose This Part
WAFER-XH2.54-2PLB makes sense when the design specifically needs a two-position vertical SMD header in the XUNPU XH2.54 family and the manufacturer’s 1 A / 125 V electrical ratings are sufficient. Its tape-and-reel packaging also fits automated surface-mount assembly better than a through-hole header when the board and mating harness are designed for this connector style.
The correct choice still depends on the mating receptacle, polarization/keying, board land pattern, mechanical retention, insertion cycles, and cable system. A visually similar XH-style connector should not be treated as mechanically interchangeable without checking the exact dimensions and mating specification.
Design Considerations
Resolve the pitch notation at the drawing level. XUNPU’s page uses the XH2.54 family designation and displays 2.54 mm in the page heading, while its basic-parameter block lists 2.5 mm. The PCB footprint and mating connector should therefore be verified from the exact manufacturer drawing rather than inferred from the rounded family name alone.
Use the stated electrical ratings. XUNPU specifies 1 A rated current and 125 V rated voltage for this family. The connector and mating system should remain within those documented limits with appropriate application margin.
Do not treat 260 °C as the operating-temperature rating. The manufacturer labels 260 °C as heat resistance. Reflow profile, exposure time, operating temperature, and long-term material limits are separate checks and should be confirmed from the applicable assembly/drawing documentation.
Check the complete mating system. Contact resistance and current performance depend on the intended plug/receptacle pair, terminal condition, conductor size, and mechanical engagement. Verify the mating connector and harness before freezing the PCB footprint.

FAQ
How many positions does WAFER-XH2.54-2PLB have?
The exact 2P ordering code is a two-position header.
What current and voltage ratings should be used?
Use the XUNPU manufacturer specifications: 1 A rated current and 125 V rated voltage.
Is the pitch 2.54 mm or 2.5 mm?
XUNPU names the family XH2.54 and shows 2.54 mm in the page heading, while the basic-parameter block lists 2.5 mm. For PCB and mating compatibility, use the exact manufacturer drawing rather than relying on either rounded text label alone.
Is 260 °C the connector’s operating temperature?
No such conclusion should be drawn. XUNPU labels 260 °C as heat resistance on this page. Operating-temperature and reflow-profile requirements must be verified separately.
