Product details

What 0.050" Pitch and 50 Positions Mean for Your Board Layout

At 0.050" (1.27mm) pitch, the 87401-125 packs 50 positions into a 2-row layout — 25 per row. Surface mount termination means the header is placed by pick-and-place and reflow soldered — no wave-solder step, which simplifies the assembly line but demands careful paste stencil design for the 1.27mm pitch pads.

Contact Plating and Temperature Range: Field-Service Durability

The post finish is tin-lead with a 100µin thickness, compatible with standard solder pastes. Rated from -55°C to 130°C, the glass-filled thermoplastic housing handles automotive underhood and outdoor telecom cabinet temperature swings without warping.

Frequently asked questions

What is the pitch of 87401-125?

The mating pitch is 0.050" (1.27mm), with the same row spacing. This is a 2-row, 50-position header.

Is 87401-125 a surface mount header?

Yes, it is a surface mount (SMT) header with solder termination — designed for reflow assembly.

Is 87401-125 RoHS compliant?

No, it is marked RoHS non-compliant due to the tin-lead post finish. Verify your project's RoHS exemption policy before ordering.
