1090C4-12V Incandescent Panel Indicator Equivalent & Substitute Parts

Part Overview

The 1090C4-12V is an incandescent panel indicator manufactured by Visual Communications Company (VCC). This component is a white incandescent indicator with a 12V operating voltage, designed for panel-mount applications with a round 0.50" (12.70mm) cutout. The part features wire leads measuring 4.6" (116.84mm) for direct soldering or connection to circuit boards.

The 1090C4-12V is classified as Obsolete. Locating equivalent or substitute components is necessary for ongoing maintenance, repair, and production support of legacy equipment utilizing this indicator. Substitute parts must maintain electrical compatibility (12V operation) and mechanical compatibility (0.50" round panel cutout, round flat-top lens style) while accommodating different termination methods or updated product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 1090C4-12V is based on maintaining electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• Voltage rating must be 12V
• Lamp type must be Incandescent
• Lamp color must be White
• Lens color must be White

Mechanical Compatibility Requirements:

• Panel cutout shape must be Round
• Panel cutout dimensions must be 0.50" (12.70mm)
• Lens style must be Round with Flat Top

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected status

Substitute parts may differ in termination style (wire leads versus quick connect terminals) provided all electrical and mechanical parameters remain identical. The 1090QC4-12V qualifies as a substitute because it maintains all critical electrical parameters, mechanical fit dimensions, and compliance certifications while offering an alternative termination method (Quick Connect - 0.187" (4.7mm) instead of wire leads).

Parameter Comparison

Engineering Selection Recommendations

1090C4-12V (Main Part - Obsolete Status)

The 1090C4-12V is classified as Obsolete. This part remains available with 1017 pieces in current inventory. Selection of this part is appropriate only for direct replacement in existing equipment where the wire lead termination is required and the specific 4.6" (116.84mm) lead length is compatible with the circuit board layout.

1090QC4-12V (Substitute - Not For New Designs Status)

The 1090QC4-12V is classified as Not For New Designs. This substitute maintains complete electrical and mechanical compatibility with the 1090C4-12V while offering Quick Connect termination (0.187" (4.7mm) terminals) instead of wire leads. This termination difference provides an alternative connection method suitable for applications where quick-disconnect capability is beneficial. The 1090QC4-12V is available with 1034 pieces in current inventory.

Both parts maintain ROHS3 compliance and REACH Unaffected status. Selection between these two substitutes depends solely on termination method requirements: wire leads for direct soldering or quick connect terminals for removable connections. All other electrical and mechanical parameters are identical, ensuring functional equivalence in panel-mount applications requiring a 12V white incandescent indicator with a 0.50" round panel cutout.

Frequently Asked Questions (FAQ)

Q: Can the 1090QC4-12V directly replace the 1090C4-12V in existing equipment?

A: The 1090QC4-12V is electrically and mechanically compatible with the 1090C4-12V. Both operate at 12V, feature identical white incandescent lamps, and fit the same 0.50" (12.70mm) round panel cutout. The primary difference is the termination method: the 1090C4-12V uses 4.6" wire leads while the 1090QC4-12V uses 0.187" quick connect terminals. Replacement is feasible if the circuit board connection method can accommodate quick connect terminals.

Q: What is the significance of the different termination styles?

A: The 1090C4-12V termination (wire leads - 4.6" (116.84mm)) is designed for direct soldering to circuit boards or wiring harnesses. The 1090QC4-12V termination (quick connect - 0.187" (4.7mm)) uses spade connectors for removable connections. The choice depends on the application's connection requirements and whether the circuit board or connector system supports quick connect terminals.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 1090C4-12V and 1090QC4-12V are ROHS3 Compliant and REACH Unaffected, meeting current environmental and chemical substance regulations.

Q: Why are both parts classified as legacy (Obsolete or Not For New Designs)?

A: Both parts represent older incandescent indicator technology. The 1090C4-12V is Obsolete, indicating it is no longer in active production. The 1090QC4-12V is classified as Not For New Designs, indicating it remains available for legacy support but is not recommended for new product development. For new designs, current LED-based indicator alternatives should be evaluated.

Q: What parameters must match for a part to be considered a true substitute?

A: Critical matching parameters are: 12V voltage rating, incandescent lamp type, white lamp color, white lens color, round flat-top lens style, round panel cutout shape, and 0.50" (12.70mm) panel cutout dimensions. Termination style may differ between substitutes. Compliance certifications (ROHS3, REACH) should be maintained.

Q: Is the 1090QC4-12V the only available substitute for the 1090C4-12V?

A: Based on the provided substitute list, the 1090QC4-12V is the documented equivalent part. Both components are manufactured by Visual Communications Company and share identical electrical and mechanical specifications except for termination method.
