Q: What are the differences among M6351FNS-5(8)-b; M6351FNS-5(8)-b1; M6351FNS-5(8)-b(A); M6351FNS-5(8)-b1(A) terminals? How to choose the right one?
A: All belong to the M6351FNS 6.35mm fully insulated male straight terminal series.
The coding rules are as follows:
①: 5(8) stands for terminal tab thickness: 0.8mm.
②: b / b1 represent different insulation inner diameter and wire gauge range, both for AWG16-14 wiring. b=Ins. Dia, Max: 4.06mm; b1=Ins. Dia, Max: 6.60mm.
③: Without suffix (A) adopts Hole Detent structure with strong locking and anti-vibration performance; with suffix (A) adopts Dimple Detent structure for smoother plug and unplug with standard locking force.
Selection guide:
①: Choose b / b1 with no suffix (A) for scenarios requiring firm locking and vibration resistance;
②: Select b(A) / b1(A) for applications needing easy insertion and extraction with conventional locking demand;
③: Pick b or b1 according to your actual wire outer diameter to ensure perfect crimping and insulation fit.
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: 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 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: This terminal fits AWG16-14 wires, with a cross-sectional area suitable for medium current electrical and general automotive wiring applications.
Q: What is the difference between models with and without suffix (A)?
①Without suffix (A):
Adopts a Hole Detent structure. It locks by circular hole engagement, featuring strong retention, anti-disengagement and vibration resistance.
②With suffix (A):
Adopts a Dimple Detent structure. It positions by spring dimple compression, providing smoother insertion and extraction with standard locking force.
Q: What is a 6.35mm male disconnect terminal?
A: 6.35mm male disconnect terminal is a kind of 0.250 inch spade terminal with a 6.35mm tab width.
It is a fully insulated wire-to-connect component made of tin-plated brass and flame retardant nylon, widely mated with 6.35mm female terminals for quick connection and disconnection.
It is commonly used in automotive wiring harnesses, home appliances and industrial equipment for circuit connection, available in different wire gauge ranges of AWG12-10, AWG16-14 and AWG22-18.
Q: What is the difference between mating with straight female terminals and flag female terminals? How to choose the right type?
A: Both straight female terminals and flag female terminals can mate with the same specification male disconnect terminals.
The main differences are installation direction, wiring layout and application scenario:
①: Straight female terminal adopts inline straight structure, with wiring and connection in a straight horizontal direction.
②: Flag female terminal features a right-angle flag design, turning the wiring direction by 90 degrees for side routing and space-saving installation.
③: Electrical performance, current rating and detent locking structure are identical for both types under the same tab size and wire gauge.
Selection guide:
①: Choose straight female terminals for linear wiring, straight-through harness layout and sufficient installation space.
②: Select flag female terminals for limited mounting space, 90° angle routing and compact equipment internal wiring.
③: Keep the same tab width and AWG wire gauge to ensure perfect mating with corresponding male terminals.
Q: What are the differences among 0.110", 0.187", 0.205" and 0.250" terminals? How to choose the right size?
A: These numbers refer to the tab width of quick disconnect terminals in inches:
0.110" is the smallest size for low-current signal and auxiliary circuits;
0.187" is the most common general-purpose size for medium light-current wiring;
0.205" offers larger contact area for higher current and more stable connection;
0.250" is the largest size, designed for heavy-duty and high-power main circuits.
For selection, match the terminal tab width to your mating connector, wire AWG, working current and installation space. Use smaller sizes for signal lines, and larger sizes for main power and high-current applications.
