Product Highlights

✅ Blind‑Mating & Self‑Alignment: Built‑in guide ribs allow XY offset tolerance, absorb PCB assembly misalignment, and reduce mating damage during automated assembly

✅ High‑Speed Signal Integrity: Supports up to 20 Gbps, compatible with MIPI, PCIe, SATA, USB3.1 Gen2 high‑speed interfaces

✅ Fixed Mated Height: 2.5 mm: Precise board‑to‑board stacking height control for mechanical enclosure fit‑out

✅ SMT Reel Packaging: Direct pick‑and‑place for SMT assembly line, no secondary manual handling required

✅ Multi‑pin Options: 20/24/30/40/50/60 positions for flexible PCB pin‑out scaling

Note Avoid prolonged high‑temperature dwell time; nickel barrier suppresses solder wicking risk

Cross‑Reference / Alternative 

Direct drop‑in replacement for Hirose DF40HC(2.5)‑xxDS‑0.4V(51) series (20/24/30/40/50/60P)

  • Same footprint, same 2.5 mm mated height, same 0.4 mm pitch
  • Compatible mating male plug: DF40HB(2.5)‑xxDP‑0.4V(51) series
  • No PCB layout modification required for substitution; verified pin‑to‑pin compatibility.

Note: Not affiliated with Hirose; our part is functional equivalent replacement.



Product Feature

  1. Self‑alignment guide ribs mitigate blind‑mating mis‑insertion risk for automated assembly
  2. Reinforced housing ribs improve shock & vibration resistance in end‑product
  3. Nickel anti‑wicking barrier prevents solder creep onto contact zone during reflow soldering
  4. Optimized high‑speed contact geometry for stable signal integrity on high‑speed differential signals
  5. Vacuum pick‑and‑place surface ready for mass SMT production
  6. Multiple pin counts (20‑24‑30‑40‑50‑60P) to match different I/O requirements



Product Advantages

  • Drop‑in substitute: Replace original HRS long‑lead‑time components without PCB redesign
  • Blind‑mate tolerance: Reduces assembly scrap caused by board offset misalignment
  • Reel‑to‑SMT ready: Full reel embossed tape packaging, feeds directly into pick‑and‑place machines
  • Consistent high‑speed performance: Stable impedance performance for high‑speed interfaces
  • Flexible MOQ & sample support: Fast sample validation for engineering prototypes
  • Domestic factory lead‑time advantage: Shorter lead‑time vs international brands' long back‑orders

Application
  • Industrial control embedded boards
  • Medical compact stacked PCB modules
  • Imaging / MIPI camera interface hardware
  • High‑speed storage, SATA / PCIe peripheral interconnections
  • Hand‑held portable devices, compact stacked PCB assemblies
  • Test & measurement equipment, stacked mezzanine board designs


Packing 

  • Standard embossed carrier tape for SMT automatic pick‑and‑place machine
  • Directly usable on customer SMT production line; no repacking needed

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.

Customer Selection 

  1. Confirm required pin count: 20/24/30/40/50/60P; confirm mating male part number
  2. Confirm mated stack height: This series is fixed at 2.5 mm; verify mechanical housing clearance
  3. High‑speed application: Ensure differential routing matches reference design impedance
  4. Assembly: Reel packaging for volume SMT; request free samples for reflow profile test first
  5. Substitution check: Verify footprint compatibility before full‑order release; use free samples for prototype testing.



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: 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.

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.
