ROHM Red Single-Heterojunction Through-Hole LEDs Made in Malaysia NOS 96-Piece Lot

LEDs / Indicator Lamps • SKU RFB00537

$7.95

96-piece lot of NOS ROHM red single-heterojunction light-emitting diodes manufactured in Malaysia. These are traditional discrete through-hole LEDs with clear molded lenses and two leads for PCB mounting, equipment repair, restoration work, prototypes, and general electronic applications.

The original stock identification describes these devices as ROHM red single-heterojunction LEDs. When operated with the correct polarity and an appropriate current-limiting resistor, they produce visible red light and can be used for status indication, power indication, fault indication, logic-state indication, control panels, test fixtures, display functions, and other visual signaling applications.

Red through-hole LEDs of this style were widely used in radios, communications equipment, test instruments, industrial controls, computers, audio equipment, consumer electronics, power supplies, control panels, and countless other electronic assemblies.

The manufacturer is identified as ROHM and the stock is marked as manufactured in Malaysia. The exact ROHM catalog part number is not available from the loose component or supplied identification, so specific electrical values such as forward voltage, maximum current, wavelength, luminous intensity, viewing angle, and reverse-voltage rating should not be assumed without testing or original documentation.

Because the exact ROHM part number is unknown, lifecycle status cannot be reliably classified as active, discontinued, or obsolete. These parts are therefore accurately offered as vintage NOS ROHM electronic component stock without making an unsupported obsolete-status claim.

HISTORICAL BACKGROUND:

ROHM developed into a major international manufacturer of semiconductors, LEDs, integrated circuits, resistors, and other electronic components used throughout consumer, industrial, communications, automotive, computing, audio, and instrumentation equipment.

Visible red LEDs were among the earliest semiconductor light sources to become widely used in commercial electronic equipment. During the 1970s and 1980s, red LEDs increasingly replaced miniature incandescent indicator lamps because of their low power consumption, low heat generation, fast switching, small physical size, and long operating life.

Single-heterojunction LED technology belongs to the early generations of practical visible-light semiconductor devices. Red LEDs became particularly common as power and status indicators on radios, receivers, amplifiers, computers, test equipment, communications hardware, industrial controls, and other electronic systems.

These NOS ROHM devices are useful for vintage electronics repair and restoration as well as laboratory work, educational projects, prototypes, hobby electronics, control-panel projects, and general bench inventory. Their traditional through-hole construction also makes them convenient for hand assembly and repair work compared with modern miniature surface-mount LEDs.
