Product details

The SM04B-ZESS-TB(LF)(SN): Four positions in a single row keep the connector narrow, so it fits on a board edge where z-height is tight.

Current and Voltage — Signal-Duty, Not Power

This header mates with JST ZE series crimp receptacles — the 4-position receptacle housing (part number ZE-04) and matching crimp terminals (SZE-002T-P0.3 for 24-28 AWG, or SZE-61T-P0.3 for 20-24 AWG) complete the wire-to-board connection. The (LF)(SN) suffix indicates lead-free (LF) soldering compatibility and tin (SN) plating on the termination tails — standard RoHS-compliant finish that reflows well with SAC solder profiles.

Frequently asked questions

Where can I buy SM04B-ZESS-TB(LF)(SN) and how do I get a price?

No stock-holding claim is made — availability is verified per inquiry.

What is the mating connector for SM04B-ZESS-TB(LF)(SN)?

The mating half is a JST ZE series 4-position crimp receptacle housing (ZE-04) loaded with SZE-002T-P0.3 terminals for 24-28 AWG wire or SZE-61T-P0.3 for 20-24 AWG. The locking ramp on this header engages the receptacle latch for a vibration-resistant connection.

What does the (LF)(SN) suffix mean on SM04B-ZESS-TB(LF)(SN)?

(LF) designates lead-free solderability — the termination tails are plated for RoHS-compliant soldering. (SN) indicates the contact finish on the post is tin. The part is fully RoHS compliant.
