Board-to-Board Connectors for Japanese Engineering Teams
Japanese hardware and procurement teams usually specify a connector by pitch, スタック高さ (mated height), 極数 (pin count) and footprint compatibility before discussing price. This page maps those terms to CPTGR part numbers and lists the files normally requested at the design-review stage.
How buyers in Japan search
Common queries include 基板対基板コネクタ, 0.4mmピッチ コネクタ, スタック高さ 1.5mm, 100極 メザニン and DF40 互換 / 代替. Yahoo! Japan and Bing carry a significant share of Japanese search alongside Google, so we keep specifications in static HTML that any of these crawlers can read without rendering JavaScript.
Japanese teams frequently ask for a single plug that covers several receptacle heights. The B118 family is designed exactly that way: one common plug BB0118P{NN}A paired with height-graded receptacles BB0113R to BB0118R for 1.5 / 2.0 / 2.5 / 3.0 / 3.5 / 4.0mm stacks.
Recommended series for Japanese programs
Camera modules, LiDAR modules, automotive board-to-board links and high-speed main-to-sub-board connections are the primary applications for B118 (0.4mm, 10-100 pins) and B104E/B104F (0.5mm, 10-80 pins, 3.0-5.0mm stack, DF12 family). For very dense wearable or optical designs, BB0088 provides a 0.175mm four-row BTB with a 0.5mm mated height.
RF requirements are separate: S01 and S06 are RF test sockets for repeated production and final-test insertion on the signal chain, while C01/C02/C03 are micro coaxial connectors used to attach antennas. They are different device categories and should not be specified interchangeably. FC0019 is a vertical drawer-type FPC connector at 0.5mm pitch and 4.5mm height for tight module layouts.
Engineering package and commercial terms
Provide the current part number, board thickness, available height, pin count and reflow profile. We return the compatible plug and receptacle set, recommended land pattern and stencil aperture guidance, 2D drawing and 3D STEP model. At 0.4mm pitch and 100 pins, coplanarity before reflow and ground-pin placement for return paths are the two points we review first.
Standard samples are typically prepared in 3-7 days. MOQ, tape-and-reel packaging, delivery terms and compliance documentation are confirmed per part number at quotation. All BTB series use full Insertmold construction with plating after molding for consistent terminal geometry across production lots.
Contact and response window
Our engineering and sales team works from Dongguan (UTC+8), one hour behind JST. Messages received during Japanese business hours are normally answered the same day by email at eng201@cptgr.com or by phone at +86 186 7678 9529. Email attachments are accepted for drawing and photo exchange; please include the part number in the first message.
Technical references: the part number index lists all 220 part numbers, and the cross-reference table maps DF40 / DF12 / BK13C06 family positions to CPTGR series. Both are static pages that open without a login.
FAQ
Is B118 a drop-in replacement for DF40?
B118 maps to the 0.4mm DF40 family across six stack heights with a common plug. Confirm footprint, pin count, keying and mating height against your drawing before release; the series name is used for cross-reference intent only.
Can I order receptacles only?
Yes. Plug and receptacle can be supplied separately. Many teams stock one plug and two or three height-graded receptacles.
Do you provide 3D STEP models?
Yes, 3D STEP models and 2D drawings are supplied on request together with the recommended footprint.
What is the MOQ for a 100-pin B118 build?
MOQ is confirmed at quotation and depends on pin count, plating and packaging. Standard builds are the fastest route for samples.
