NKK Switches JB15HKP Equivalent & Substitute Parts

Part Overview

The NKK Switches JB15HKP is an active SPST-NO tactile switch rated for 0.125A at 24VDC with top actuated through-hole mounting. This component is designed for applications requiring momentary contact switching with sealed construction (IP67 rated). Substitute parts become necessary when addressing specific application constraints such as packaging requirements, actuator height specifications, mechanical life cycle demands, or inventory availability across different manufacturing sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JB15HKP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary contact)
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Termination style: PC Pin
• RoHS compliance: ROHS3 Compliant
• Voltage rating: 24VDC nominal

Variable Parameters Affecting Substitution:

• Contact current rating (0.125A primary vs. 0.05A substitutes)
• Outline dimensions (10.00mm x 10.00mm primary vs. 6.00mm x 6.00mm substitutes)
• Actuator height off PCB
• Operating force (265gf primary vs. 160gf-260gf substitutes)
• Mechanical life cycles (1,000,000 primary vs. 100,000 substitutes)
• Operating temperature range
• Ingress protection rating
• Packaging format (Tray, Bag, Bulk)

The three substitute parts (1-1825910-5, 2-1825910-2, 3-1825910-5) from TE Connectivity ALCOSWITCH Switches meet the mandatory compatibility criteria but differ in contact rating, mechanical life, and physical dimensions, requiring application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

Contact Current Rating Consideration: The JB15HKP is rated for 0.125A at 24VDC, while all three substitute parts are rated for 0.05A at 24VDC. Substitution is only appropriate for applications where the actual circuit current does not exceed 0.05A. Applications requiring the full 0.125A rating cannot use these substitutes.

Mechanical Life Consideration: The JB15HKP provides 1,000,000 mechanical cycles, while substitute parts provide 100,000 cycles. Applications with high-cycle switching requirements must account for this tenfold reduction in mechanical life expectancy.

Physical Footprint Consideration: The JB15HKP occupies a 10.00mm x 10.00mm outline, while all substitutes occupy 6.00mm x 6.00mm. Substitution is suitable only for designs where the smaller footprint is compatible with PCB layout constraints.

Ingress Protection Consideration: The JB15HKP provides IP67 rating (dust tight, waterproof). The substitute parts do not specify ingress protection ratings. Applications requiring sealed operation must evaluate whether the absence of specified IP67 protection is acceptable.

Temperature Range Consideration: The JB15HKP operates from -25°C to 70°C. Substitute part 1-1825910-5 extends to -40°C to 105°C, while parts 2-1825910-2 and 3-1825910-5 operate from -35°C to 85°C. Selection depends on application temperature requirements.

Compliance Status: All parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating, supporting equivalent regulatory and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part if my application requires 0.125A switching current? A: No. The substitute parts are rated for 0.05A maximum at 24VDC. Using them in applications exceeding 0.05A will result in contact degradation and potential failure. The JB15HKP must be used for 0.125A applications.

Q: What is the impact of reduced mechanical life on substitute parts? A: Substitute parts provide 100,000 mechanical cycles compared to the JB15HKP's 1,000,000 cycles. For applications with frequent switching (high cycle count), the substitute parts will reach end-of-life ten times faster. Evaluate your application's switching frequency to determine if 100,000 cycles is sufficient.

Q: Are the substitute parts suitable for sealed or waterproof applications? A: The JB15HKP is rated IP67 (dust tight, waterproof). The substitute parts do not specify ingress protection ratings. If your application requires sealed operation or exposure to moisture, the JB15HKP is the appropriate choice.

Q: What are the differences between the three substitute parts? A: All three substitute parts (1-1825910-5, 2-1825910-2, 3-1825910-5) share identical electrical specifications (0.05A @ 24VDC, SPST-NO, 100,000 cycles) and outline dimensions (6.00mm x 6.00mm). They differ in actuator height (9.50mm, 8.00mm, and 8.50mm respectively), operating force (260gf vs. 160gf), operating temperature range, and packaging format (Bag vs. Bulk). Selection depends on PCB clearance requirements and packaging needs.

Q: Can I substitute based on packaging format alone? A: No. Packaging format (Tray, Bag, Bulk) affects supply chain and handling but does not determine electrical or mechanical compatibility. Substitution decisions must be based on electrical ratings, mechanical life, physical dimensions, and environmental specifications.

Q: Is the smaller 6.00mm x 6.00mm footprint of substitute parts compatible with my design? A: The smaller footprint is compatible only if your PCB layout and mechanical design accommodate the reduced dimensions. Verify that the 6.00mm x 6.00mm outline and specified actuator heights (8.00mm to 9.50mm) do not conflict with surrounding components or enclosure constraints.

Q: Do all parts meet the same regulatory requirements? A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory compliance is equivalent across all options.
