Product details

What the 2.50mm Pitch and 3A Rating Mean for Your Layout

The S2B-EH(LF)(SN): The latch lock fastening type provides positive retention against moderate vibration — the mating receptacle clicks into place and stays until deliberately released.

This header mates with JST EH series crimp receptacles (e.g., EHR-2) using the matching tin-plated male pins — the latch lock engages with the receptacle housing for a vibration-resistant connection. Termination is press-fit, solder — the through-hole posts (0.126" / 3.20mm long) are soldered to the PCB; the press-fit feature provides initial retention during wave or hand soldering.

Frequently asked questions

Where can I buy JST S2B-EH(LF)(SN) and how is it quoted?

No stock-holding claim; submit a BOM quantity for a firm quote.

What is the pitch of S2B-EH(LF)(SN)?

0.098" (2.50mm) pitch — this is the centre-to-centre spacing between adjacent pins.

Is S2B-EH(LF)(SN) RoHS compliant?

Yes — the (LF)(SN) suffix indicates RoHS compliance and tin-plated contacts.

What crimp terminal works with this header?

JST EH series crimp terminals (male pin side is integral to the header; the mating receptacle uses female crimp terminals such as SEH-001T-P0.6). Confirm wire gauge with the terminal datasheet.
