Product details

3-Pin Breakaway Header for Board-to-Board Signal Routing

The 77315-113-03LF: The square male pins mate with standard 0.025" square-post receptacles.

Right-Angle Footprint and Board Fit

The post length of 0.136" (3.46mm) sets the solder tail depth — the through-hole fillet forms within a standard 1.6mm board. Insulation height is 0.094" (2.40mm), leaving clearance for components on adjacent layers.

The base product number is 77315; the -03LF suffix indicates the 3-position variant with gold mating finish and tin-plated posts. RoHS compliance is standard for the LF suffix.

Frequently asked questions

Where can I buy 77315-113-03LF and what is the lead time?

The 77315-113-03LF is an active-production part. Submit a quote request with your target quantity and we'll provide a firm lead time.

Is 77315-113-03LF RoHS compliant?

Yes, the -LF suffix designates lead-free / RoHS-compliant finish. The contact posts are tin-plated (2.00µm thickness), and the mating surface is gold (30.0µin).

What is the pinout of 77315-113-03LF?

It is a single-row, 3-position unshrouded header with all positions loaded. The pinout is a straight 1×3 array at 0.100" pitch — pin 1 is typically marked by a square pad or chamfer on the housing. No keying or polarization; the unshrouded design allows mating with any standard 0.025" square-post receptacle.

What is the difference between 77315-113-03LF and 77315-113-03?

The -03 variant (without LF) typically uses a different plating combination — confirm the exact finish from the manufacturer's part-numbering system. Both share the same 3-position, 2.54mm pitch, right-angle through-hole footprint.

Is 77315-113-03LF equivalent to Samtec TSW-103-07-T-S?

Both are 3-position, single-row, 0.100" pitch unshrouded headers with right-angle orientation. The Amphenol part carries a 30.0µin gold finish for higher mating cycle life. Pinout and footprint are functionally interchangeable, but the plating difference matters for corrosion resistance and cycle count.
