CRT Display Tube
Available on back-order
Description
A storage indicator tube 31LN1 for converting electrical signals into a visible image stored for a period of time, which is determined by the erasure mode.
31LN1: identification and purpose
31LN1 is classified as a CRT Display Tube and converts electrical signals into visual information within the applicable electronic display assembly. Selection requires comparison of the complete designation, electrical ratings, construction, base or connector, mounting arrangement and passport data. Matching opening characters or a similar appearance do not establish identical characteristics or interchangeability.
A family name describes the general equipment class but does not replace the documentation for the exact execution. A suffix, additional digit, colour, bulb, base or housing variant can identify a material difference. 31LN1 should therefore be ordered by the product marking rather than by appearance alone.
Function within the equipment
The item converts electrical signals into visual information within the applicable electronic display assembly. Its exact operating mode is defined by the circuit and associated equipment. For lighting products, verify voltage, power, luminous output, colour, optical arrangement and fixture type. For electronic tubes and display devices, verify electrode function, heater ratings, limiting voltages and currents, cooling, pin allocation and operating range.
Numerical data retained from the original catalogue record are shown in Technical Details. Those values must be compared with the passport for the actual item. Aircraft types and systems are not assigned by analogy when reliable documentation is unavailable.
Selection and compatibility checks
Before replacement, compare the primary and alternative designations, rated voltage or current, power, base, dimensions, mass, contact arrangement, cooling requirements and environmental limits where documented. Exterior lighting units may also require confirmation of filter colour, beam direction and approved installation position.
Related members of a series may use different electrical modes, optical characteristics or mechanical interfaces. They must not be treated as interchangeable without an explicit documentary reference. General background on this equipment class is available under CRT Display Tube.
Incoming inspection and installation
Incoming inspection includes checking the marking and supporting records and examining the housing or envelope, base, contacts, connectors, mounting points, reflector, filter and seals as applicable. Electrical measurements, photometric checks or electronic-tube bench testing must follow an approved procedure.
Install the item only in the intended fixture or equipment while observing polarity, supply mode, cooling and electrical-safety requirements. Complete the functional checks prescribed after installation. External integrity alone does not demonstrate serviceability.
Related catalogue positions
Functionally related products include 23LM34V, 45LM5V, 23LM17V-1, 45LM6Ts. They are grouped by class and family for catalogue navigation and do not imply interchangeability. More items are listed in the Landing Lights, Lamps & Beacons category.
Enquiry information
An enquiry for 31LN1 should state the exact designation, quantity, required condition, marking photograph, delivery scope and required document set. When available, include the designation of the item and equipment being replaced. Price, actual availability, lead time and condition of the offered item are confirmed separately.
Final selection must use the passport, illustrated parts catalogue or approved technical documentation. Missing ratings must not be inferred from a neighboring execution; request them together with a nameplate photograph and information about the installation system.
Before supply, confirm the electrical ratings, contact or base execution and condition of the specific item. Record these details in the enquiry and compare them with the operator documentation. Do not treat a matching housing or neighboring suffix as evidence of compatibility.
