Cross‑Reference / Alternative
Drop-in footprint compatible alternative to Hirose DF40 series, JAE WP6C series, Molex 0.4mm fine pitch BTB female socket.
Same PCB land pattern, pin assignment, and stacking height. Engineers can directly replace foreign parts without PCB redesign, reducing sourcing cost & long lead time risk.
Product Feature
- Anti-foolproof anti-detent structure prevents reverse mating and pin bending
- Self-alignment floating tolerance compensates for PCB assembly misalignment
- Selective gold contact plating maintains stable contact resistance under vibration & thermal cycling
- LCP high-temperature plastic, stable dimensions after reflow soldering
- Double-row 90-pin high-density layout, ideal for compact stacked PCB modules
- Low crosstalk structure for high-speed differential signals
Product Advantages
- Same performance as big brands, shorter lead time & better cost control
- Reel tape packaging ready for SMT automatic assembly, no secondary repacking required
- In-house precision mold & 100% on-line inspection, consistent batch quality

Engineer Selection Guidance
- Confirm required mated stack height first; this defines your PCB gap
- Check high-speed signal requirement (MIPI / PCIe / USB) to verify impedance
- Confirm SMT reel packaging requirement before placing bulk order
- Send your PCB footprint or datasheet to our engineering team for compatibility review
- Request free samples for insertion, thermal cycling, and signal integrity validation before full BOM adoption
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.
