- 100% form‑fit‑function alternative for Molex 78171 /78172 series
Product Advantages
- Direct drop‑in replacement: No PCB modification required for original Molex 78171 /78172 design, fast BOM second‑sourcing
- Cost optimization: Competitive pricing vs original brand, stable mass‑supply capacity
- Assembly‑friendly: SMT tape‑reel packing, polarization anti‑mistake, reduce assembly defect rate
- Reliable battery connection: Low contact resistance, anti‑vibration lock‑structure, stable power transmission for Li‑polymer cells
- Flexible options: Multiple pin counts, tin/gold plating options, support custom cable harness service

Application
- Wearable devices & smart portable electronics
- IoT sensors & smart home small appliances
- Li‑polymer battery packs & battery management modules
- Hand‑held medical portable equipment
- Consumer small‑size power‑driven devices
- Portable testing & measuring instruments
Customer Selection Guide
- Confirm pin count: 2‑7 positions, match battery signal & power circuit requirements
- Wire gauge check: strictly use 30‑28 AWG wire; oversize wire will cause bad crimping
- Plating selection: Gold plating preferred for high‑vibration / long‑lifespan device; Tin plating for cost‑sensitive consumer products
- Assembly condition: Confirm SMT reflow temperature ≤260 ℃; header is SMT type, receptacle is crimp‑on‑wire
- Validation suggestion: Run mating test, vibration test & contact resistance test with our samples before mass‑order
- Second‑source note: Inter‑mateable with original Molex 78171 /78172 series for mixed‑supply project
FAQ
1. 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.
2. 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 about35-45 days.
3. 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 for the shipping cost
4. Q: What about your delivery time?
A: Stock goods are delivered within 1 day; customized goods are delivered within 5-7days
5. 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 are responsible for any product damage caused during delivery.

A: Weaccept T/T(Wire transfer), Western Union, and PayPal. Please make sure that we can receive the same amount as the Invoice. And you can pay in RMB. No problem.
7. Q: How about your company's quality control
A: Strictly obey ISO9001, IQC, OQC, IPQC, QA occupy 10% of our Quality department. All of our products will be tested by CCD.
8. 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
9. Q: Can you make customized products and customized packing?
A: Yes. We have made a lot of customized
products for our customers formerly (mainly wire harnesses). About customized packing, there is no problem for we put your logo or other information on the package. Just have to point out that it incurs additional cost.
