Q: What is the MOQ for 6.35mm 0.250" Insulated terminal?
A: MOQ: 5000pcs/item.
Q: What is the lead time for 6.35mm 0.250" Insulated terminal?
A: L/T: 3-4 weeks.
Q: What is the maximum temperature rating for this 6.35mm terminal?
A: The maximum temperature rating is 105ºC
Q: Can this AWG16-14 receptacle be used in automotive vibration environments?
A: Yes, this AWG16-14 receptacle, features secure contact retention that withstands typical automotive vibration levels. It is suitable for medium current circuits when installed per specifications.
Q: What is the difference between 4.75mm and 6.35mm connectors?
A: The difference is the width of the terminal tab. 4.75mm connectors are smaller and used for lighter applications, while 6.35mm
connectors handle higher currents.
Q: How do I choose the correct AWG size?
A: Select the connector based on your wire gauge. This product is designed for AWG16-14(1.31-2.08mm²) wires, ensuring a proper crimp fit.
Q: Are these connectors insulated?
A: Yes, they feature a fully insulated sleeve to prevent short circuits and improve safety.
Q: What wire size does AWG16-14 support?
A: AWG 16-14 terminals are designed for wires with a cross-sectional area suitable for medium to high current electrical applications.
Q: What certifications do HRB connectors have (UL, RoHS, REACH)?
A: HRB connectors hold UL/cUL, RoHS, and REACH certifications, plus key automotive and industrial approvals.
UL/cUL: Certified under UL 1977 (file no. E322751)
Q: What is the difference between M6350FNS-5(8)-b and M6350FNS-5(8)-b1, and how do I select the correct one for my application?
A: The only difference between M6350FNS-5(8)-b and M6350FNS-5(8)-b1 is the maximum wire insulation diameter.
All electrical performance, mating size and material specifications are exactly the same.
①M6350FNS-5(8)-b: Max wire insulation diameter 4.06 mm
②M6350FNS-5(8)-b1: Max wire insulation diameter 6.60 mm
Selection guide:
Choose -b when your wire outer insulation diameter is within 4.06 mm.
Choose -b1 if your wire insulation outer diameter ranges up to 6.60 mm.
Q: What is the difference between AWG16-14 and AWG22-18? How to select the correct wire size?
A: AWG16-14 wires have a larger cross-section and support higher current loads, ideal for main power and medium-current circuits. In contrast, AWG22-18 wires are thinner, designed for low-current and auxiliary wiring.
Choose AWG16-14 for high-power components and heavy-duty applications, while AWG22-18 is recommended for signal lines and auxiliary electrical systems.
Q: What is the difference between loose piece packing and reel packing for terminals, and how to choose the right one?
A: Loose piece packing means terminals are supplied in bulk individual bags, while reel packing winds terminals on continuous plastic reels.
①Loose packing: For manual assembly, small-batch production, lab repair and maintenance; easy to take a small quantity at a time.
②Reel packing: For automatic crimping machines and high-volume mass production; compatible with automated wiring harness equipment to improve efficiency.
Choose loose packing for manual use and small orders; choose reel packing if you use automatic crimping equipment for large-scale production.
Q: Why are there three colors — red, blue, and yellow — for the same Straight Insulated Female Receptacle (M6350 series)?
A: The red, blue, and yellow colors in the M6350 series are industry standard color coding that indicates the compatible wire gauge (AWG) and cross‑section area. All other dimensions and electrical specs are identical.
①Red (R)：AWG22–18 (0.32–0.82 mm²)
②Blue (B)：AWG16–14 (1.30–2.08 mm²)
③Yellow (Y)：AWG12–10 (3.31–5.26 mm²)
This color system enables fast, error‑free selection during manual assembly and maintenance.
