Key Parameters

Substitute Part Grouping Explanation

Substitution of the LB15SKW01-05-JC is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration: SPDT
• Current rating: 3A (AC/DC)
• Voltage rating: 125V AC / 30V DC
• Switch function: On-Mom (momentary)

Mechanical Compatibility Requirements:

• Mounting type: Panel Mount, Snap-In
• Panel cutout dimensions: Square - 16.20mm x 16.20mm
• Actuator type: Square, Button
• Termination style: Solder, Quick Connect - 0.110" (2.8mm)

Environmental & Lifecycle Requirements:

• Operating temperature: -25°C ~ 50°C
• Mechanical life: 1,000,000 Cycles
• Electrical life: 100,000 Cycles

The LB15SKW01-5C05-JC qualifies as a direct substitute based on identical electrical ratings, mechanical dimensions, mounting configuration, and lifecycle specifications. The primary difference is the illumination technology: the substitute employs LED red illumination at 5 VDC instead of incandescent red illumination at 5 VAC.

Parameter Comparison

Engineering Selection Recommendations

The LB15SKW01-5C05-JC is the qualified substitute for the obsolete LB15SKW01-05-JC. Both components maintain identical electrical and mechanical specifications, ensuring direct functional compatibility in panel-mount applications requiring SPDT 3A/125V pushbutton switching.

The substitute part carries Active product status, providing assured long-term availability and supply chain continuity compared to the obsolete main part. Both components satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The primary technical distinction is the illumination technology transition from incandescent to LED. This change requires verification that the illumination voltage supply in the host system can provide 5 VDC instead of 5 VAC. Systems with existing 5 VAC illumination supplies require circuit modification to support the LED-based substitute.

Frequently Asked Questions (FAQ)

Q: Can the LB15SKW01-5C05-JC directly replace the LB15SKW01-05-JC without any modifications?

A: Direct mechanical and electrical replacement is possible for the switch contacts and mounting. However, the illumination circuit requires modification: the main part operates on 5 VAC incandescent illumination, while the substitute requires 5 VDC LED illumination. If the host system provides only 5 VAC, the illumination supply must be redesigned to support 5 VDC.

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

A: Yes. Both the LB15SKW01-05-JC and LB15SKW01-5C05-JC require a square panel cutout of 16.20mm x 16.20mm. No mechanical modification to the panel is necessary.

Q: What is the difference in electrical performance between these two parts?

A: The electrical switching performance is identical. Both parts feature SPDT circuit configuration with 3A/125V AC and 30V DC ratings, identical mechanical life (1,000,000 cycles), and electrical life (100,000 cycles). The only functional difference is the illumination technology.

Q: Why is the main part listed as obsolete?

A: The LB15SKW01-05-JC is classified as obsolete by the manufacturer. The LB15SKW01-5C05-JC represents the active product line continuation, incorporating LED illumination technology in place of incandescent illumination.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the LB15SKW01-05-JC and LB15SKW01-5C05-JC are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement.

Q: What packaging is available for the substitute part?

A: The LB15SKW01-5C05-JC is supplied in Bulk packaging, compared to the main part's standard packaging designation.
