Overview

The VHR-3N-BK from JST Sales America Inc. is a rectangular wire-to-board connector from the VH series family, typically used as a 3-position housing for crimp contacts in low- to medium-power applications. Rectangular connectors like this are widely used for board interconnects, harness terminations, and internal wiring inside electronic equipment. The VHR-3N-BK is designed for reliable mechanical retention and stable electrical connection in compact assemblies, making it suitable for a range of consumer, industrial, and automotive-related designs where a simple, polarized multi-pin connector is needed. For exact current rating, voltage rating, pitch, and compatible contacts, refer to the official JST datasheet and VH series documentation.

Applications

• Internal wiring harness connections in consumer electronics and home appliances
• Power and signal interconnects on industrial control boards and PLC modules
• Board-to-cable connections in HVAC, white goods, and building automation systems
• Low-voltage interfaces in office equipment, printers, and instrumentation
• General-purpose wire-to-board connections in embedded and IoT controller boards
• Prototyping and custom harness assemblies where polarized, keyed connectors are required

Alternatives & Replacement

Depending on availability, lifecycle status, or specific design requirements (such as pitch, current rating, or locking style), alternative parts may be considered as replacements for the VHR-3N-BK. Any substitute should be evaluated carefully to ensure that mechanical, electrical, and environmental requirements are still met.

Recommended alternatives:

• JST Sales America Inc. ELP-02V — rectangular connector (redesign required; low compatibility score, manual review recommended)
• TE Connectivity 2132415-2 — rectangular connector (redesign required; low compatibility score, manual review recommended)
• JST Sales America Inc. SXA-001T-P0.6L — contact/connector element (redesign required; package and pin compatibility unconfirmed)
• JST Sales America Inc. SPND-001T-C0.5 — contact/connector element (redesign required; package and pin compatibility unconfirmed)
• JST Sales America Inc. SMM-003T-P0.5 — contact/connector element (redesign required; package and pin compatibility unconfirmed)
• JAE Electronics M23S05K351 — rectangular-style connector (redesign required; package and pin compatibility unconfirmed)

Engineering note: before selecting any replacement, always verify the connector’s pitch, number of positions, keying/polarization, mating interface, current and voltage ratings, operating temperature range, and mounting style. Confirm the footprint and housing dimensions against your PCB layout and harness drawings, and review creepage/clearance, contact plating, and mating part numbers to ensure full compatibility in both electrical performance and mechanical fit.
