JD7510F Keylock Switch - Equivalent & Substitute Parts

Part Overview

The JD7510F is a 3-position keylock switch manufactured by APEM Inc., configured as a DP3T (double-pole, double-throw) circuit with 4A AC rating at 125V. This component is designed for panel-mounted applications requiring secure key-actuated switching with a flat key actuator and 45° throw angle.

The JD7510F is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JD7510F is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: DP3T (double-pole, double-throw) - mandatory match
• Number of Positions: 3 positions - mandatory match
• Switch Function: Mom-On-Mom - mandatory match
• Current Rating: 4A minimum (AC or AC/DC) - mandatory match
• Voltage Rating (AC): 125V minimum - mandatory match
• Actuator Type: Flat Key - mandatory match
• Key Removable Positions: 1 only - mandatory match
• Angle of Throw: 45° - mandatory match
• Contact Material & Finish: Copper Alloy with Gold finish - mandatory match
• Mounting Type: Panel Mount - mandatory match
• Termination Style: Solder Lug - mandatory match
• Panel Cutout Dimensions: Circular 19.00mm Dia - mandatory match
• Operating Temperature Range: -30°C ~ 85°C minimum - mandatory match
• Depth Behind Flange: 32.55mm - mandatory match

The LK5FNB126N3 meets all substitution criteria. This part maintains identical mechanical and electrical specifications while offering enhanced voltage capability (28V DC in addition to 125V AC) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The LK5FNB126N3 is the direct substitute for the JD7510F. Both components are manufactured by APEM Inc. and maintain identical mechanical and electrical specifications across all critical parameters.

Compliance & Certification: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Product Status Advantage: The LK5FNB126N3 carries active product status, ensuring ongoing availability and manufacturing support. The JD7510F is obsolete, making the LK5FNB126N3 the appropriate selection for new designs and ongoing production requirements.

Electrical Enhancement: The LK5FNB126N3 provides additional DC voltage capability (28V DC) while maintaining full AC specifications, offering expanded application flexibility without compromising existing circuit compatibility.

Mechanical Compatibility: Identical panel cutout dimensions (19.00mm circular), depth behind flange (32.55mm), and termination style (solder lug) ensure direct mechanical and electrical integration into existing designs.

Frequently Asked Questions (FAQ)

Q: Can the LK5FNB126N3 directly replace the JD7510F in existing applications?

A: Yes. The LK5FNB126N3 maintains identical specifications across circuit configuration (DP3T), current rating (4A), AC voltage rating (125V), actuator type (flat key), mechanical dimensions, and termination style. Direct substitution is supported without design modification.

Q: What is the difference between the JD7510F and LK5FNB126N3?

A: The primary differences are product status and DC voltage capability. The JD7510F is obsolete; the LK5FNB126N3 is active. The LK5FNB126N3 adds 28V DC rating while maintaining all AC specifications. Both parts are electrically and mechanically equivalent for AC applications.

Q: Are there packaging differences between these parts?

A: The JD7510F packaging is listed as standard; the LK5FNB126N3 is supplied in tray packaging. Both use identical solder lug termination and panel mount configuration. Packaging format does not affect electrical or mechanical compatibility.

Q: Do both parts meet current compliance standards?

A: Yes. Both the JD7510F and LK5FNB126N3 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and use.

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

A: The JD7510F does not specify mechanical life. The LK5FNB126N3 specifies 6,000 cycles mechanical life. Both parts specify 6,000 cycles electrical life and operate across the identical temperature range (-30°C ~ 85°C).

Q: Can the LK5FNB126N3 be used in DC applications?

A: The LK5FNB126N3 is rated for 28V DC operation in addition to 125V AC. The JD7510F does not specify DC voltage capability. For DC applications, the LK5FNB126N3 provides rated DC performance; the JD7510F should be evaluated for DC suitability based on application requirements.
