Key Parameters

Substitute Part Grouping Explanation

Substitution of the JD7510E is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SP3T (single pole, three throw) - must match exactly
• Number of Positions: 3 positions - must match exactly
• Switch Function: Mom-On-Mom (momentary-on-momentary) - must match exactly
• Current Rating: Minimum 4A AC - substitute must meet or exceed
• Voltage Rating (AC): Minimum 125V AC - substitute must meet or exceed
• Actuator Type: Flat Key - must match exactly
• Key Removable Positions: 1 only - must match exactly
• Angle of Throw: 45° - must match exactly
• Contact Material & Finish: Copper Alloy with Gold finish - must match exactly
• Mounting Type: Panel Mount - must match exactly
• Termination Style: Solder Lug - must match exactly
• Panel Cutout Dimensions: Circular 19.00mm Dia - must match exactly
• Operating Temperature Range: -30°C ~ 85°C - must match or exceed
• Depth Behind Flange: 32.55mm - must match exactly

The LK5ENB126N3 meets all substitution criteria while offering enhanced DC voltage capability (28V DC) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The LK5ENB126N3 is a direct functional equivalent to the JD7510E. Both components are manufactured by APEM Inc. and share identical electrical and mechanical specifications across all critical parameters. The LK5ENB126N3 offers the advantage of active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. The LK5ENB126N3 provides additional DC voltage capability (28V DC) not specified in the JD7510E, making it suitable for applications requiring dual AC/DC operation without compromising AC-only functionality.

Frequently Asked Questions (FAQ)

Q: Can the LK5ENB126N3 directly replace the JD7510E in existing applications?

A: Yes. The LK5ENB126N3 meets all electrical and mechanical specifications of the JD7510E. Panel cutout dimensions, mounting depth, termination style, and solder lug configuration are identical. Direct substitution is possible without mechanical or electrical redesign.

Q: What is the difference between the JD7510E and LK5ENB126N3?

A: The primary differences are product status and DC voltage capability. The JD7510E is obsolete; the LK5ENB126N3 is active. The LK5ENB126N3 supports both AC (125V) and DC (28V) operation, while the JD7510E specifies AC only. All other parameters are identical.

Q: Are there packaging differences between these parts?

A: Yes. The JD7510E packaging is not specified in available documentation. The LK5ENB126N3 is supplied in Tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the LK5ENB126N3 maintain the same electrical life rating?

A: Yes. Both parts are rated for 6,000 electrical cycles. The LK5ENB126N3 additionally specifies 6,000 mechanical life cycles, providing complete lifecycle documentation.

Q: Are both parts RoHS compliant?

A: Yes. Both the JD7510E and LK5ENB126N3 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Can the LK5ENB126N3 be used in DC applications?

A: Yes. The LK5ENB126N3 is rated for 28V DC operation in addition to 125V AC. The JD7510E does not specify DC capability. If your application requires DC switching, the LK5ENB126N3 provides this functionality.
