What is the difference between mezzanine and coplanar board-to-board connectors?

Mezzanine connectors stack two PCBs in parallel with a controlled height gap (3mm–30mm), allowing vertical board stacking. Coplanar connectors connect two PCBs side by side on the same plane. Mezzanine is used in dense multi-board assemblies; coplanar is used when boards need to be in the same horizontal plane.

What stacking heights are available?

Standard stacking heights range from 3mm to 30mm. Custom heights are available for OEM designs. The stacking height determines the PCB-to-PCB distance in the assembled connector pair.

What is the MOQ for board-to-board connectors?

Standard MOQ is 1,000 pieces per model. Free samples are available for qualified engineering projects. Contact sales@vistarelectronics.com with your project details.

Key Features

📏

0.5mm – 2.54mm Full Pitch Range

Complete pitch range from ultra-fine 0.5mm for compact mobile designs to standard 2.54mm for development boards. All pitches available in multiple pin counts and row configurations.

📦

Stacking Heights 3 – 30mm

Controlled stacking heights from 3mm to 30mm for precise PCB-to-PCB spacing. Custom heights available for OEM designs where standard dimensions don't fit.

⚡

Up to 5A Per Contact

From signal-grade 0.5A (0.5mm pitch) to power-grade 5A (2.54mm pitch). High-current BTB variants available for mixed signal and power applications on a single connector.

🔗

Mezzanine & Coplanar

Both mezzanine (vertical stacking) and coplanar (side-by-side) configurations. Mezzanine enables compact multi-board assemblies; coplanar suits modular daughterboard designs.

🏭

SMT & DIP — Production Ready

SMT versions in tape-and-reel for pick-and-place automated assembly. DIP through-hole versions for wave soldering. Both packaging formats available from stock.

✅

RoHS 3 & REACH Compliant

All board-to-board connectors comply with RoHS 3 (EU Directive 2015/863) and REACH SVHC. Suitable for EU, North American, and all regulated export markets.

Common Questions

Frequently Asked Questions

What pitch board-to-board connectors do you offer?

We offer BTB connectors in standard pitches of 0.5mm, 1.0mm, 1.27mm, 2.0mm, and 2.54mm. Ultra-fine pitch (0.4mm) is available as a custom OEM option. The 2.54mm (0.1 inch) pitch is the most common for development boards and backplane systems, while 0.5mm is used in smartphones and ultra-compact consumer devices.

What is the difference between mezzanine and coplanar BTB connectors?

Mezzanine connectors stack two PCBs in parallel with a controlled height gap between them, allowing compact vertical multi-board assemblies. The stacking height (3–30mm) defines the PCB-to-PCB distance. Coplanar connectors connect two boards side by side on the same horizontal plane — used when the boards need to be in the same plane, such as modular daughtercard designs. See also our FPC connectors for flexible board connections.

Can I get custom stacking heights?

Yes. Standard stacking heights range from 3mm to 30mm in common increments. For OEM projects requiring non-standard heights or custom pin counts, our engineering team can produce custom configurations. Please provide your PCB stack-up drawing and contact sales@vistarelectronics.com.

What is the MOQ and lead time?

Standard MOQ is 1,000 pieces per model with a 2–4 week production lead time. Free samples are available for qualified engineering projects. For urgent requirements, in-stock standard models (2.54mm pin headers) can ship within 3–5 business days.

Are your BTB connectors compatible with standard footprints?

Yes. All standard pitch BTB connectors (0.5mm, 1.0mm, 1.27mm, 2.0mm, 2.54mm) are manufactured to IEC and JEDEC standard footprints, ensuring compatibility with existing PCB layouts. Datasheets with full land pattern dimensions are available on each product page.
