Cross‑Reference / Alternative
Drop-in compatible replacement for Hirose DF40TC(2.0)-120DS-0.4 series receptacle. Pinout, footprint, stacking height, and mating interface fully matched. Alternative cross-check: Compare with Molex, Amphenol 0.4mm high-speed BTB series for second-source qualification.
Note: Our part is a form-fit-function equivalent, ideal for BOM cost-down & supply risk mitigation.
Product Feature
- Built-in guide ribs for blind mating & self-alignment, robust anti-damage during manual/automated assembly
- Anti-solder wicking structure prevents solder capillary up into contact area during reflow
- Shock-absorbing rib design absorbs vibration & mating stress, maintains stable contact resistance
- LCP high-temp housing withstands lead-free reflow, suitable for high-temperature working environment
- Optimized contact spring geometry, stable high-speed signal integrity, low crosstalk
- 120Pin high density, saves PCB space for compact electronics
Product Advantages
🔹 Second-source alternative to Hirose, shorter lead time and better MOQ flexibility vs original brand
🔹 100% continuity & visual inspection before shipment, low failure rate
🔹 High-speed-tuned contact structure, validated signal integrity for high-speed differential signals
🔹 Robust foolproof design lowers assembly reject rate in mass production
🔹 Custom pin count/stacking height available, supporting project pre-sample verification
🔹 Full documentation support: Datasheet, 3D STEP, PCB footprint drawing, test report

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.
