0.4mm Narrow Pitch Board-to-Board Mezzanine Connector Double Row 12-Pin Compatible DF40TC-12DP-0.4 Male Board Connector
Product Highlights
✅ Blind Mating & Self-Alignment: Built-in guide ribs, 0.33mm lateral tolerance, anti-misinsertion foolproof design, absorbs assembly offset & avoids pin damage during manual/automated mating. ✅ High-Speed Performance: Supports up to 20Gbps signal transmission, compatible with PCIe Gen4, MIPI, USB4 Gen2 for high-density signal routing.
✅ Defined Mated Height: Fixed stacking height for precise PCB gap control; low-profile double-row layout saves PCB footprint.

Cross‑Reference / Alternative
Direct pin-to-pin, footprint-compatible replacement for Hirose DF40TC-12DP-0.4. Drop-in alternative without PCB layout redesign. Also cross-reference to Molex SlimStack & Kyocera 5804 series 0.4mm B2B mezzanine connectors for alternate sourcing.
Product Feature
- Anti-foolproof blind mating structure, wide self-alignment range to reduce assembly scrap.
- Nickel barrier stops solder wicking during reflow, protects gold contact.
- Reinforced shock-absorbing ribs, good vibration & drop resistance.
- Fully enclosed contact when mated, blocks dust & flux contamination.
- Compact double-row narrow pitch, maximizes PCB space utilization.
- SMT pad layout matches original DF40TC footprint for direct substitution.
Product Advantages
- Shorter lead time vs imported HRS original parts; avoids long OEM backlog.
- Consistent plating & contact force for stable high-speed signal integrity.
- Strict 100% visual & electrical inspection before shipment.
- Reel tape packaging ready for SMT pick & place, no repacking required for your assembly line.
- Flexible customization: adjust stacking height, pin count, or gold thickness upon request.
Application
Industrial embedded boards,
wearable devices,
medical sensor modules,
tablet & laptop sub-boards,
camera / LiDAR modules,
portable testing instruments,
AI edge computing hardware.
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
- Sample order: 3 working days
- Mass production order: 1‑3 weeks, subject to configuration & order quantity
Factory Certification & Custom Service
Certifications: ISO9001, RoHS, REACH
- MOQ: Low MOQ for standard parts
- Sample Policy: Support free samples; customer only bears freight cost; fast sample release
- Customization: Custom pin count, stack height, plating thickness, housing color available upon request. Send your PCB drawing for engineering review.
Engineer Selection Guidance
- Confirm Mated Stacking Height first; this is the most critical parameter for PCB gap design.
- Verify pin count, signal speed requirements (if >10Gbps, we will run an impedance check).
- Check operating temperature range and vibration environment for industrial/medical use.
- For drop-in replacement: confirm PCB footprint matches DF40TC-12DP-0.4 before mass production.
- Request free samples for SMT assembly test & signal integrity validation.
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.
