Compatibility & Cross‑Reference

This O‑shape empty‑pin female header serves as a functional alternative for mainstream international series, compatible with standard 2.54mm male pin header footprint.

Note: Always verify mechanical dimension, plating requirement and PCB footprint before BOM substitution.

• Compatible footprint reference: Molex KK‑254, JAE / JST 2.54mm pitch header series
• 1:1 custom modification available if exact pin‑to‑pin drop‑in replacement is required.

Product Features

1. O‑shape round female cavity: stable contact, low contact resistance, anti‑vibration performance
2. Empty‑pin blocking function: skip unused circuits for customer PCB layout optimization
3. Flexible mechanical variant: straight, right‑angle, SMT, custom insulator height
4. SMT vacuum pick‑up cap design: compatible with full‑auto SMT placement machine
5. Multiple plating options: tin for cost‑sensitive projects; gold for high‑reliability, long‑life devices
6. Single‑row / dual‑row flexible position count, supports non‑standard pin‑number customization

Product Advantage

• Factory-direct ODM/OEM: adjust plastic height, empty‑pin position, terminal length per your drawing
• Production‑ready packaging: Tape & Reel for auto‑assembly; Tube for prototype & small batch
• Strict batch‑to‑batch consistency, full‑range in‑house electrical & mechanical testing
• Cost‑effective alternative to imported brands without sacrificing reliability
• Quick sample turnaround for engineering validation; stable mass‑production capacity
• Technical support: footprint suggestion, mating‑pair verification, assembly guidance

Application

• Industrial control boards & PLC peripheral modules
• IoT hardware, sensor modules, gateway equipment
• Consumer electronics, smart home mainboard interconnection
• Medical device internal board‑to‑board connection
• Test & measurement equipment, laboratory instruments
• Robotics, automation equipment internal wiring
• New‑energy auxiliary control unit

Packaging Method

1. Tape & Reel: For SMT version with vacuum cap. Direct feeding to automatic pick‑and‑place machine, suitable for high‑volume mass production.
2. Tube (Tube Packing): For THT straight/right-angle samples & small‑batch orders, manual insertion or semi‑auto assembly.

Please specify packaging requirement when placing order.

Lead Time

• Samples: 3 working days for standard items
• Bulk production order: 1‑3 weeks (depends on pin‑count, plating & packing type; custom modified parts need extra time)

Factory Certification & Custom Service

• Certifications: RoHS, REACH, UL‑94V‑0 material certification
• Sample Policy: Support free samples / fast sample delivery for engineering evaluation
• MOQ: Standard parts low MOQ; Custom‑structure MOQ upon project evaluation
• Custom scope: insulator height, empty‑pin position, pin length, plating thickness, mounting form, special packaging solution
• Service: Provide drawings, 2D/3D files, test report for your project review

Engineer Selection Guide (Engineer Tips)

1. Confirm mounting type: THT‑Straight / Right‑angle / SMT; SMT order must specify vacuum pick‑up cap requirement
2. Define row count & position count; mark exact empty‑pin blocking position
3. Confirm insulator height, terminal tail length for your PCB thickness
4. Select plating: Tin for general‑use; Gold for high‑vibration, long‑lifespan, or harsh‑environment applications
5. Specify packaging: Tape & Reel for SMT auto‑line; Tube for manual assembly
6. Send us your drawing or sample for cross‑check if a drop‑in replacement for an existing foreign part number is needed
