Z-221RH

LED Indication - Discrete Overview

The Z-221RH is a T-1 3/4 (5mm) standard straight through-hole LED from JKL Components Corp. It features a red diffused lens and operates at a forward voltage of 2.0V to 2.5V with a typical current of 20.0mA. The device emits light at a peak wavelength of 625nm and functions within an ambient temperature range of -40°C to +85°C. This discrete indicator is designed for panel mounting applications requiring reliable visual signaling.

LED Indication - Discrete Feature Summary

• Red diffused T-1 3/4 form factor for clear visibility
• Through-hole radial package construction
• Standard straight lead configuration

LED Indication - Discrete Applications

• Panel mount status indicators
• Equipment power state signaling
• Control board visual feedback

LED Indication - Discrete Procurement Notes

Verify component obsolescence status before procurement as the Z-221RH is listed as obsolete by major distributors. Confirm availability of equivalent substitutes such as part number 151051RS11000 if active inventory is required. Ensure that replacement components match the original electrical specifications and mechanical dimensions to maintain system compatibility without redesigning the host circuit or PCB layout.

LED Indication - Discrete Selection Notes

Select this component when a red, diffused T-1 3/4 LED is specifically required for legacy designs. Consider the 2.0V forward voltage drop when designing drive circuits to ensure proper current limiting. Evaluate thermal management requirements given the -40°C to +85°C operating range. Verify that the radial through-hole package aligns with existing manufacturing processes and assembly equipment capabilities.

LED Indication - Discrete Part Context

This part belongs to the Z-221 series of T-1 3/4 LEDs manufactured by JKL Components Corp. The series includes variants with different colors and lens types, such as the Z-221G for green and Z-221A for amber. These components share similar mechanical footprints and electrical characteristics, allowing for potential color upgrades or replacements within compatible systems while maintaining consistent physical integration.

LED Indication - Discrete Replacement Considerations

Available substitute part numbers include 151051RS11000. Verify that any replacement matches the 5mm T-1 3/4 form factor and red diffused output. Ensure electrical parameters like forward voltage and current ratings are compatible with existing circuit designs to prevent performance degradation or component failure.
