Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1050QA2 is determined by the following critical parameters that must align between the original and substitute component:

Mechanical Compatibility:

• Panel cutout shape: Round
• Panel cutout dimensions: 0.50" (12.70mm)
• Lens style: Round with Domed Top
• Termination style: Quick Connect - 0.187" (4.7mm)

Electrical Compatibility:

• Voltage rating: 105V ~ 125V AC range
• Ratings classification: AC

Regulatory Compliance:

• RoHS3 Compliant status
• REACH Unaffected status
• Moisture Sensitivity Level 1

The 1092QA2-125VAC qualifies as a substitute based on matching mechanical interface specifications (panel cutout dimensions, lens configuration, and termination style) and electrical ratings within the specified AC voltage range. The transition from neon to LED technology maintains functional equivalence while providing enhanced brightness characteristics and reduced power consumption.

Parameter Comparison

Engineering Selection Recommendations

The 1092QA2-125VAC serves as the designated substitute for the obsolete 1050QA2 based on the following engineering criteria:

Mechanical Interface Compatibility: Both components share identical panel cutout dimensions (0.50" / 12.70mm), lens configuration (round with domed top), and termination interface (quick connect 0.187" / 4.7mm). Direct mechanical substitution is supported without panel modification.

Electrical Ratings: The 1092QA2-125VAC operates at 125V AC, which falls within the upper range of the original 1050QA2 specification (105V ~ 125V AC). This ensures compatibility with existing AC power supply circuits.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement and deployment.

Product Status: The 1092QA2-125VAC is classified as active, ensuring ongoing availability, technical support, and supply chain continuity compared to the obsolete 1050QA2.

Frequently Asked Questions (FAQ)

Q: Can the 1092QA2-125VAC be directly installed in place of the 1050QA2?

A: Yes. Both components feature identical panel cutout dimensions (0.50" / 12.70mm), matching lens styles (round with domed top), and compatible quick connect termination (0.187" / 4.7mm). No panel modification is required for mechanical substitution.

Q: What is the voltage compatibility between these two parts?

A: The 1050QA2 operates across 105V ~ 125V AC. The 1092QA2-125VAC operates at 125V AC, which is within the upper specification range of the original component. Both are rated for AC applications.

Q: Why is the 1050QA2 classified as obsolete?

A: The 1050QA2 is an obsolete neon indicator. The 1092QA2-125VAC represents the current active equivalent, utilizing LED technology instead of neon. This transition reflects industry-wide adoption of LED indicators for improved reliability, brightness, and energy efficiency.

Q: Are there differences in brightness or visibility between these components?

A: The 1092QA2-125VAC provides a millicandela rating of 7000mcd with diffused lens transparency. The original 1050QA2 specifications do not include millicandela or transparency data. The LED substitute typically offers enhanced brightness and consistent visibility characteristics.

Q: Do both components meet current regulatory requirements?

A: Yes. Both the 1050QA2 and 1092QA2-125VAC are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory standards for electronic component procurement.

Q: What is the current consumption of the substitute part?

A: The 1092QA2-125VAC is rated for 25mA at 125V AC. The original 1050QA2 current specification is not provided in the available documentation.

Q: Are packaging considerations different between these parts?

A: The 1092QA2-125VAC is supplied in bag packaging. Packaging format does not affect functional compatibility or panel installation.
