Cross‑Reference / Alternative
This 0.8 mm 38‑pin curved‑terminal BTB plug is engineered as a drop‑in functional alternative for selected Molex SlimStack®, JAE, Amphenol BergStak® 0.8 mm series BTB plugs.
- Matches critical footprint, mated height, electrical & mechanical performance for direct replacement in existing PCB projects.
- No PCB layout revision required for most cases; please verify the dimension drawing before mass production.
- Cost‑optimized lead‑time advantage vs original imported components for volume projects.
Product Feature
- Curved spring‑beam terminals deliver stable multi‑point contact, resist vibration & thermal‑cycle stress.
- Self‑alignment blind‑mating chamfer guards pins against mis‑insertion damage for auto‑assembly production.
- Mylar backing tape holds fine‑pitch terminals coplanar, prevents distortion during tape‑reel transport & reflow.
- Gold‑over‑nickel plating maintains low contact resistance even in humid or slightly corrosive working environments.
- Compact 0.8 mm high‑density pitch saves valuable PCB stacking space.
- Strict coplanarity control for zero‑defect SMT pick‑and‑place yields.
Product Advantages
🔹 Lower assembly risk: Self‑alignment tolerance design reduces manual & robotic mating failure rate.
🔹 High‑speed + high‑current combined capability: One connector handles both power supply and high‑speed differential signals.
🔹 Mass‑production ready: Reel packaging directly compatible with standard SMT pick‑and‑place machines.
🔹 Cost‑effective substitution: Functional equivalent to famous international brand parts, shortening procurement lead time.
🔹 Reliable consistency: In‑house stamping, molding, plating & final inspection, stable batch‑to‑batch performance.
🔹 Flexible support: Free samples & fast prototyping for your engineering validation.

Engineer Selection Guidance
- Confirm actual mated height matches your PCB stack‑up & housing mechanical clearance.
- Verify current per‑pin load: do not exceed rated 1.0 A per contact for continuous operation.
- For high‑speed signal paths, follow our recommended PCB stack‑up & differential‑pair routing suggestion.
- Re‑check mating partner receptacle compatibility; cross‑reference does not guarantee 100% pin‑to‑pin without drawing confirmation.
- SMT production: retain Mylar tape before reflow soldering; peel off after soldering is finished.
- Submit BOM list to our engineering team if you need cross‑reference verification for your existing project.

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.

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.
