LB15SKW01-12-JC Equivalent & Substitute Parts

Part Overview

The LB15SKW01-12-JC is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a 3A/125V AC rating. This panel-mount, snap-in component is designed for applications requiring momentary switching with visual feedback via incandescent red illumination at 12 VAC. The part is currently classified as obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

The LB15SKW01-12-JC has one identified substitute within the NKK Switches LB series: LB15SKW01-5C12-JC. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Current and voltage ratings (3A AC/DC, 125V AC, 30V DC)
• Mounting type and panel cutout dimensions (Panel Mount, Snap-In, 16.20mm x 16.20mm square)
• Actuator type and color (Square button, Clear with Red Filter/Diffuser)
• Termination style (Solder, Quick Connect - 0.110")
• Operating temperature range (-25°C ~ 50°C)
• Mechanical and electrical life specifications

The primary difference between the main part and its substitute lies in the illumination technology and voltage specification, which does not affect electrical or mechanical compatibility in applications where the illumination source can be adapted.

Parameter Comparison

Engineering Selection Recommendations

The LB15SKW01-5C12-JC is the designated substitute for the obsolete LB15SKW01-12-JC. Both components maintain identical electrical and mechanical specifications across all critical switching parameters, including circuit configuration, current/voltage ratings, mounting dimensions, and operational life cycles. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. The transition from incandescent to LED illumination technology represents a modernization within the same product family, with the primary consideration being the change from 12 VAC to 12 VDC illumination voltage. This difference requires circuit-level evaluation to confirm compatibility with the host system's power supply architecture.

Frequently Asked Questions (FAQ)

Q: Can LB15SKW01-5C12-JC directly replace LB15SKW01-12-JC without circuit modifications?

A: Mechanical and electrical switching compatibility is complete. However, the illumination voltage differs (12 VAC vs. 12 VDC). If the host system provides 12 VAC illumination power, a power supply modification or adapter circuit is required to support the LED illumination in the substitute part.

Q: Are the panel cutout dimensions identical between these parts?

A: Yes. Both components require a square 16.20mm x 16.20mm panel cutout and use identical snap-in mounting mechanisms. No mechanical redesign of the panel interface is necessary.

Q: What is the difference between incandescent and LED illumination in these switches?

A: The main part uses incandescent illumination (12 VAC), while the substitute uses LED illumination (12 VDC). LED technology offers longer operational life and lower power consumption. The color output (red) is equivalent in both versions.

Q: Are both parts suitable for the same electrical load conditions?

A: Yes. Both components are rated for 3A at 125V AC and 30V DC, with identical electrical life specifications of 100,000 cycles. Switching performance and load capacity are equivalent.

Q: What is the significance of the "Active" product status for the substitute part?

A: Active status indicates that LB15SKW01-5C12-JC is currently manufactured and available through standard distribution channels, providing long-term supply security compared to the obsolete main part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited), meeting current regulatory and environmental requirements.
