Cross‑Reference / Alternative
Direct alternative replacement for HRS DF40C-80DP-0.4V(51). Pinout, footprint, stack height, and mating interface are fully matched. Drop-in replacement without PCB redesign.
Cross-reference: Hirose DF40C series, comparable to Amphenol BergStak 0.4 mm fine-pitch B2B mezzanine connectors.
Product Feature
- Anti-misalignment guiding structure, supports blind mating & self-alignment, absorbs PCB stacking positional deviation.
- Nickel barrier terminal design, effectively blocks solder wicking during SMT reflow soldering.
- Reinforced housing with shock-absorbing ribs improves vibration & shock resistance.
- Right-angle SMT termination, optimized pick & place pad for automatic mounting.
- High-frequency-optimized terminal geometry to maintain stable high-speed signal integrity.
- Compact low-profile mezzanine stacking design, saves internal device space.
Product Advantages
- Drop-in replacement: No PCB layout change, direct substitute for HRS DF40C-80DP-0.4V(51), mitigates long lead time & supply shortage risk of imported brands.
- Stable high-speed performance: Tuned impedance control for high-speed differential interfaces.
- High assembly yield: Built-in blind mate & anti-dummy key design to avoid reverse insertion and pin bending.
- Automation-friendly: Standard reel packaging for direct SMT pick-and-place.
- Factory customization available: Adjust stack height, pin count, and plating thickness per project requirements.
Application
High-speed mezzanine PCB stacking for:
- Medical imaging modules
- Industrial control boards

- Optical communication sub-assemblies
Lead Time
- Sample order: 3 working days
- Mass production order: 1‑3 weeks, subject to configuration & order quantity
Factory Certification & Custom Service
- Certifications: ISO9001, RoHS, REACH compliant
- Sample Policy: Free samples supported, fast sample turnaround
- MOQ: Low MOQ for standard parts; custom configurations MOQ upon evaluation
- Custom capability: Custom pin count, mated stacking height, plating thickness, mechanical modification, special packaging according to your drawing/specification.
Engineer Selection Guidance
- Confirm required mated stack height first; this is the core dimension for mezzanine PCB stackup.
- Verify high-speed interface bandwidth requirement (≤20Gbps).
- Check PCB space; right-angle SMT footprint matches original HRS DF40C-80DP-0.4V(51).
- If your application has a vibration/shock environment, confirm the mating cycle and operating temperature range.
- Request free samples for signal integrity test & SMT assembly verification before mass production.
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.
