Cross‑Reference / Alternative
Drop-in replacement for Hirose FX18 series 0.8mm pitch 40-pin BTB receptacle.
- Same PCB footprint & pin assignment; no PCB layout modification required
- Intermateable with original Hirose mating header
- Cost-effective second source, solves long lead time & supply shortage risk
- Also an alternative to comparable Molex / TE 0.8mm pitch 40P BTB series
Product Feature
- Anti-dummy key + self-alignment guide structure, supports blind mating, avoids reverse insertion & pin bending
- Phosphor bronze spring contact maintains stable contact force after repeated mating
- LCP high-temperature housing, withstands lead-free reflow soldering without deformation
- Fine 0.8mm pitch, 40-pin high density, saves PCB space for compact electronics
- SMT terminal with flat solder pad, excellent coplanarity for stable pick & place
Product Advantages
- Supply stability: Factory direct production, no MOQ barrier for samples, bypass long OEM lead time
- Engineer-verified footprint: Pre-tested compatibility, reduce your validation cycle
- Consistent plating control: Uniform gold plating thickness, stable signal & anti-corrosion
- Automation ready: Tape & reel packaging for SMT pick-and-place machines
- Customizable: Adjust mated height, plating thickness, pin count per your project
Application
Industrial control modules,
IoT smart devices,
handheld instruments,
medical electronics,
display modules,
automotive auxiliary electronics,
consumer slim devices,
communication gateway PCBA board stacking
Packaging
Tape & Reel (Reel packaging): Standard reel packaging for SMT pick‑and‑place machine. Parts can be directly loaded onto your automated production line without repacking. Cut‑tape service is available for small‑batch prototypes.
Lead Time

Engineer Selection Guidance
- Confirm required Mated Height first; we have multiple stacking height options for 0.8mm 40P series
- Verify PCB footprint against our provided datasheet before layout freeze
- For high-speed signal applications, request an impedance test report
- If your mating part is an original Hirose header, confirm mating compatibility before mass trial
- Operating temperature >85℃ or vibration-heavy environments, please inform us for a contact upgrade
FAQ
Q: Do you have a catalogue? Can you send me the catalogue to check all your products?
A: Yes, you can contact us online or send an Email to get the catalogue.
Q: I can't find the product in your catalogue. Can you make this product for me?
A: Our catalogue shows most of our products, but not all. Just let us know what product you need and how many you want. If we do not have it, we can also design and make a new mould to produce it. For your reference, making an ordinary mould will take about 35-45 days.
Q: Can you provide a sample? Are these samples free?
A: Yes, we provide 5-10 pcs of connector free samples for testing. But you have to pay the shipping cost
Q: What about your delivery time?
A: Stock goods are delivered within 1 day; customized goods are delivered within 5-7days
Q: How to ship my order?
A: For small packages, send them by Express, such as DHL, FedEx, UPS, TNT, EMS. That's Door-to-Door service. For big packages, we can send them by Air or by sea. We use standard export cartons. We will be responsible for any product damage caused during delivery.
6. Q: What kind of payment do you accept? Can I pay RMB?
A: Weaccept T/T(Wire transfer), Western Union, and PayPal. Please be sure that we can receive the same amount as the Invoice. And you can pay money in RMB. No problem.
7. Q: How about your company's quality control
A: Strictly follow ISO9001; IQC, OQC, IPQC, and QA occupy 10% of our Quality department. The CCD test is applied to 99% of our company's product applications.
Q: I need your price list of all your products. Do you have a price list?
A: We do not have a price list of all of our products. Because we have so many items, it's impossible to make all of their prices on a list, and the prices are always changing because of the material cost and quantity. And you can give us a list of all of the items you need; we will confirm carefully one by one and give you a specification and price list
Q: Can you make customized products and customized packing?
A: Yes. We have made a lot of customized
products for our customers before (mainly wire harnesses). About customized packing, there is no problem; we can put your logo or other information on the packing. Just have to point out that it will cause some additional cost.
Q: What certificates do you have?
A: CE, CQC, UL, ISO9001, ISO14001, IATF16949, ISO45001, QC080000, etc.
