Product details

3-Position LEN Header, 3.00mm Pitch — Obsolete Status

The JST BM03B-LENSS-A-TB(HF) is a 3-position header from the LEN series, designed for board-to-wire interconnect. It uses a 0.118" (3.00mm) pitch, which gives enough spacing for the 300V rating without crowding the board layout. Rated 3A per circuit with 22 AWG wire, this header carries signal-level current — the 3A limit is set by the wire gauge, not the contact itself. The tin-plated contacts are suited for moderate mating-cycle duty in consumer or industrial internal harnesses.

Fit and Mating

The 3.00mm pitch is standard across the LEN series, so the board footprint stays consistent if you swap position counts within the family.

Frequently asked questions

Is BM03B-LENSS-A-TB(HF) obsolete?

Knowing the part is obsolete helps buyers decide to look for a replacement immediately rather than attempt to purchase a non-stocked item.

What is the equivalent of BM03B-LENSS-A-TB(HF)?

Buyers need a direct drop-in replacement to avoid redesign when the original is no longer available.

Where can I buy BM03B-LENSS-A-TB(HF) in stock?

Sourcing an obsolete part requires knowing which distributors still carry inventory before committing to a redesign.

Does BM03B-LENSS-A-TB(HF) have a lead-free finish?

RoHS compliance is mandatory for many applications, so confirming the tin finish is lead-free avoids regulatory issues.

What is the mounting style and pitch of BM03B-LENSS-A-TB(HF)?

Design engineers must verify the surface-mount right-angle orientation and 3mm pitch match their PCB layout.

Is there a cross reference for BM03B-LENSS-A-TB(HF) to JST LEN series?

Cross-referencing ensures the replacement part is mechanically and electrically compatible with existing mating connectors.
