Product details

1.27mm Pitch, 10-Position Dual-Row SMT Header

The 20021121-00010C4LF: The 1.27mm pitch allows dense routing on standard two-layer PCBs while keeping the footprint compact.

The 1A ceiling is typical for 1.27mm-pitch headers and limits the per-circuit current to stay within the housing temperature rise.

Unshrouded Design and Mating Considerations

The male pin contact length is 0.120" (3.05mm) — this sets the mating depth with the corresponding receptacle. Confirm the receptacle's pin acceptance depth to ensure full engagement.

The base product number is 20021121. Peer variants include the 12-position 20021121-00012C4LF and the 16-position 20021121-00016C4LF, both with identical pitch, plating, and ratings. For a gold flash option (thinner mating finish), see 20021121-00010C1LF.

Frequently asked questions

Where can I buy 20021121-00010C4LF and how do I get a price?

Submit a request with your target quantity and we will confirm availability and current pricing. No stock-holding claim is made; each quote reflects the market at that time.

What is the difference between 20021121-00010C4LF and a shrouded header?

This is an unshrouded header — the pins are exposed with no plastic shroud around them. A shrouded header has a plastic wall that protects the pins and provides keying to prevent mis-mating. The unshrouded design saves board space but offers less mechanical protection and no polarisation.
