QL484YT

LED Indication - Discrete Overview

The QL484YT is a single-color LED indicator manufactured by onsemi, designed for through-hole mounting in a T-1 radial package. It features an inverted cone lens configuration with yellow coloration. The component is classified as obsolete and is no longer in active production. It does not comply with RoHS standards, indicating the presence of restricted substances. The device operates within standard industrial temperature ranges typical for discrete LEDs.

LED Indication - Discrete Feature Summary

• Inverted cone lens design for specific light distribution
• Yellow single-color emission
• Through-hole radial leaded package

LED Indication - Discrete Applications

• Panel status indication
• Equipment power signaling
• Industrial control panels

LED Indication - Discrete Procurement Notes

This component is officially discontinued and marked as obsolete by the manufacturer. Availability is strictly limited to existing stock or third-party distributors. Verification of authenticity and lot date codes is critical due to the end-of-life status. Compliance documentation confirms non-RoHS status, requiring careful review for projects with environmental restrictions.

LED Indication - Discrete Selection Notes

Designers should consider this part only for maintenance or legacy system repairs where original specifications are mandatory. New designs must avoid this component due to its obsolete status and lack of RoHS compliance. Alternative modern equivalents with similar form factors and electrical characteristics should be evaluated for new product development to ensure supply chain stability.

LED Indication - Discrete Part Context

QL484YT belongs to the QL484 series of T-1 single-color LEDs from onsemi. This series includes variants with different colors such as red (QL484IT). The T-1 package is a traditional size for panel-mount indicators. The family focuses on simple visual signaling applications without complex driving requirements.

LED Indication - Discrete Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Due to the obsolete status, generic T-1 yellow LEDs may serve as functional replacements if mechanical and optical parameters align. Cross-referencing datasheets for forward voltage and current ratings is essential when selecting alternatives.
