Key Parameters

Substitute Part Grouping Explanation

The LB26CKW01-28-JC has one identified equivalent substitute: LB26CKW01-5C24-JC. Substitution eligibility is determined by the following critical parameters that must remain constant:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current rating (3A AC/DC)
• Voltage ratings (125V AC / 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Actuator type (Round Button)
• Panel cutout dimensions (22.00mm circular)
• Termination style (Solder, Quick Connect - 0.110")
• Operating temperature range (-25°C to 50°C)
• Mechanical and electrical life ratings

The substitute part maintains all these critical parameters. The primary difference lies in the illumination specification: the main part uses incandescent red illumination at 28 VAC/DC, while the substitute uses LED red illumination at 24 VDC. This distinction is significant for circuit design and power supply considerations but does not affect the core switching functionality.

Parameter Comparison

Engineering Selection Recommendations

The LB26CKW01-5C24-JC is the direct functional equivalent for the obsolete LB26CKW01-28-JC. Both parts maintain identical electrical switching characteristics, mechanical specifications, and environmental ratings. The substitute part holds active product status, ensuring ongoing availability and supply chain continuity.

Selection between these parts depends on illumination circuit requirements. The main part operates with incandescent illumination requiring 28 VAC/DC supply, while the substitute uses LED illumination at 24 VDC. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The LED-based substitute offers reduced power consumption compared to the incandescent version, which may provide secondary benefits in power budget-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can LB26CKW01-5C24-JC directly replace LB26CKW01-28-JC in existing designs?

A: Yes, for switching functionality. The substitute maintains identical DPDT circuit configuration, 3A current rating, 125V AC / 30V DC voltage ratings, and mechanical specifications. However, the illumination circuit must be adapted: the substitute requires 24 VDC supply instead of 28 VAC/DC, necessitating circuit redesign for the indicator light portion.

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

A: The illumination technology and voltage requirement differ. LB26CKW01-28-JC uses incandescent red illumination at 28 VAC/DC, while LB26CKW01-5C24-JC uses LED red illumination at 24 VDC. All switching and mechanical parameters remain identical.

Q: Are both parts panel mount compatible with the same cutout dimensions?

A: Yes. Both parts require a 22.00mm circular panel cutout and use identical snap-in mounting mechanisms. Physical installation is interchangeable.

Q: What is the significance of the product status difference?

A: LB26CKW01-28-JC is classified as obsolete, indicating discontinued production. LB26CKW01-5C24-JC maintains active status, ensuring current manufacturing, availability, and technical support from NKK Switches.

Q: Do both parts meet current compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What are the termination options for these switches?

A: Both parts use identical termination: Solder and Quick Connect - 0.110" (2.8mm). This allows flexible integration into both soldered and quick-connect circuit implementations.
