Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1050QN4 is based on the following critical parameters that must align between the original and substitute component:

Mandatory Compatibility Parameters:

• Panel cutout shape: Round
• Panel cutout dimensions: 0.50" (12.70mm)
• Termination style: Quick Connect - 0.187" (4.7mm)
• Voltage rating: 105V to 125V AC range
• RoHS3 compliance status
• Moisture sensitivity level: 1 (Unlimited)

The 1050QN4 is identified as obsolete. The substitute part 1092QC2-125VAC maintains mechanical compatibility through identical panel cutout specifications and termination style, enabling direct physical installation in existing panel designs. Both components operate within the specified voltage range and share equivalent environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 1050QN4 neon panel indicator is obsolete and no longer in active production. The 1092QC2-125VAC LED panel indicator is the identified substitute, currently in active production status with full inventory availability.

Substitution Basis:

• Both components share identical panel cutout dimensions (0.50" / 12.70mm) and round shape, ensuring mechanical compatibility with existing panel designs
• Both utilize identical quick connect termination at 0.187" (4.7mm), enabling direct electrical connection without adapter modifications
• Both operate within the AC voltage range specified for the original application (125V nominal)
• Both maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1)
• The substitute part is manufactured by the same original equipment manufacturer (VCC), ensuring design consistency and quality standards

The transition from neon to LED technology in the substitute part represents a functional upgrade in terms of current efficiency and operational characteristics, while maintaining full mechanical and electrical interface compatibility.
