4301F25/27

LED Indication - Discrete Overview

The 4301F25/27 is a dual-color LED indicator manufactured by Visual Communications Company (VCC). It utilizes a T-1 (3mm) radial package with a diffused lens. The component emits green light at a peak wavelength of 569nm and yellow light at 588nm. It is designed for through-hole mounting on printed circuit boards. The part status is officially listed as obsolete or not recommended for new designs.

LED Indication - Discrete Feature Summary

• Dual-color emission capability providing distinct green and yellow visual signals within a single compact unit
• Radial lead configuration suitable for standard through-hole PCB assembly processes
• Diffused lens design to ensure uniform light distribution across the indicator surface

LED Indication - Discrete Applications

• Temperature monitoring systems requiring dual-state visual feedback
• Compact electronic equipment needing space-saving dual-color indicators
• Industrial control panels utilizing T-1 form factor components

LED Indication - Discrete Procurement Notes

This component is classified as obsolete and no longer in active manufacturing. Procurement should focus on verifying the authenticity of existing stock from authorized distributors. Buyers must confirm that the specific lot matches the required dual-color specifications, as availability is limited to surplus inventory rather than fresh production runs.

LED Indication - Discrete Selection Notes

Engineers selecting this part must account for its obsolete status when designing new products. Alternative solutions should be evaluated if long-term supply stability is required. For existing designs, verify that the T-1 package dimensions and electrical characteristics remain compatible with the current board layout before sourcing replacement units from secondary markets.

LED Indication - Discrete Part Context

Visual Communications Company specializes in human-machine interface components, including panel mount indicators and LEDs. The 4301F25/27 belongs to their discrete LED indication portfolio, specifically targeting applications where dual-color signaling is necessary within a small physical footprint. The company provides global distribution support for its legacy and current product lines.

LED Indication - Discrete Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, engineers should consult VCC technical support for potential modern equivalents or evaluate generic T-1 dual-color LEDs with matching electrical parameters.
