Parameter Comparison

Engineering Selection Recommendations

The LK6PNB126N3 is the qualified substitute for the obsolete JD7509P. Both components are manufactured by APEM Inc. and maintain identical mechanical and electrical specifications for AC operation at 125V with 4A current capacity. The LK6PNB126N3 carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The LK6PNB126N3 provides additional DC voltage capability (28V) without compromising AC performance, making it suitable for applications requiring dual AC/DC operation.

Frequently Asked Questions (FAQ)

Q: Can the LK6PNB126N3 directly replace the JD7509P in existing designs?

A: Yes. The LK6PNB126N3 maintains identical mechanical dimensions (19.00mm circular panel cutout, 27.55mm depth), electrical ratings for AC operation (4A at 125V), and termination style (solder lug). Panel-mount installation and operational characteristics are equivalent.

Q: What is the primary difference between these two parts?

A: The LK6PNB126N3 is an active product with expanded DC voltage capability (28V DC), whereas the JD7509P is obsolete with AC-only specifications. Both deliver identical performance in AC applications.

Q: Are there packaging differences between the JD7509P and LK6PNB126N3?

A: The JD7509P packaging is not specified in available documentation. The LK6PNB126N3 is supplied in tray packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet current compliance standards?

A: Yes. Both the JD7509P and LK6PNB126N3 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the mechanical life specification for these switches?

A: The JD7509P does not specify mechanical life. The LK6PNB126N3 specifies 6,000 cycles mechanical life. Both parts deliver 6,000 cycles electrical life.
