Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB25SKW01-12-JC is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-Mom momentary operation)
• Current and voltage ratings (3A at 125V AC / 30V DC)
• Mounting type and panel cutout dimensions (Panel Mount, Snap-In; Square 16.20mm x 16.20mm)
• 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 (1,000,000 and 100,000 cycles respectively)

The LB25SKW01-5C12-JC qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary difference is the illumination technology: the substitute uses LED red illumination at 12 VDC instead of incandescent at 12 VAC. This change maintains functional compatibility while offering improved reliability and reduced power consumption.

Parameter Comparison

Engineering Selection Recommendations

The LB25SKW01-5C12-JC is the qualified substitute for the obsolete LB25SKW01-12-JC. Both components maintain identical electrical performance specifications, mechanical durability ratings, and regulatory compliance status (ROHS3 Compliant, REACH Unaffected). The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The transition from incandescent to LED illumination represents a technology upgrade within the same product family. Both illumination types deliver equivalent functional performance in panel-mounted applications. The substitute operates on 12 VDC rather than 12 VAC, requiring verification that the system power supply can accommodate this voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the LB25SKW01-5C12-JC directly replace the LB25SKW01-12-JC in existing assemblies?

A: Yes, the substitute part maintains identical panel cutout dimensions (16.20mm x 16.20mm), termination style, and electrical ratings. Physical installation and electrical connectivity are fully compatible. The primary consideration is the illumination voltage change from 12 VAC to 12 VDC.

Q: What is the difference between the incandescent and LED illumination options?

A: The main part uses incandescent red illumination powered at 12 VAC. The substitute uses LED red illumination powered at 12 VDC. Both provide equivalent visual indication. LED technology offers extended operational life and reduced power consumption compared to incandescent sources.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected. Regulatory compliance is equivalent across both components.

Q: Why is the original part classified as obsolete?

A: The LB25SKW01-12-JC is no longer in active production. The LB25SKW01-5C12-JC represents the current active equivalent within the LB series, incorporating LED illumination technology.

Q: What packaging options are available for the substitute part?

A: The LB25SKW01-5C12-JC is supplied in bulk packaging, with 789 pieces currently in stock.
