Key Parameters

Substitute Part Grouping Explanation

The LK5BNB126N3 qualifies as a direct substitute for the JD7510B based on the following critical parameters:

• Circuit Configuration: Both parts are DPDT with 2 positions and On-Mom function
• Current Rating: Both rated for 4A
• Voltage Rating - AC: Both rated for 125V AC
• Actuator Type: Both feature flat key actuation
• Key Removable Positions: Both allow key removal in 1 position only
• Angle of Throw: Both have 45° throw angle
• Contact Material & Finish: Both use copper alloy contacts with gold finish
• Mounting Type: Both are panel mount with identical 19.00mm circular cutout
• Termination Style: Both use solder lug termination
• Depth Behind Flange: Both measure 32.55mm
• Operating Temperature Range: Both operate from -30°C to 85°C
• Electrical Life: Both rated for 6,000 cycles
• Compliance: Both are ROHS3 compliant, REACH unaffected, and MSL 1

The LK5BNB126N3 provides enhanced voltage capability with additional 28V DC rating, while maintaining full compatibility with all AC specifications of the JD7510B.

Frequently Asked Questions (FAQ)

Q: Can the LK5BNB126N3 directly replace the JD7510B in existing designs?

A: Yes. The LK5BNB126N3 is mechanically and electrically compatible with the JD7510B. Identical panel cutout dimensions (19.00mm circular), depth behind flange (32.55mm), and termination style (solder lug) enable direct substitution without PCB or panel modifications.

Q: What is the difference between the JD7510B and LK5BNB126N3?

A: The primary difference is product status and voltage capability. The JD7510B is obsolete, while the LK5BNB126N3 is active. The LK5BNB126N3 adds 28V DC rating capability. All other electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: Yes. The JD7510B is supplied in standard packaging, while the LK5BNB126N3 is supplied in tray packaging. This does not affect functional compatibility or performance.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the JD7510B and LK5BNB126N3 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the electrical life rating for these switches?

A: Both parts are rated for 6,000 electrical cycles, providing equivalent operational durability.

Q: Are the operating temperature ranges the same?

A: Yes. Both parts operate across the identical temperature range of -30°C to 85°C.
