LED Panel Indicator 5593601003 Equivalent & Substitute Parts

Part Overview

The Dialight 5593601003 is a snap-in LED panel indicator featuring dual-color operation with green and yellow lamp outputs. This component is designed for panel-mount applications requiring visual status indication with 6-inch wire leads and a 5mm T-1 3/4 lens form factor. The part is currently obsolete, making identification of compatible substitutes essential for ongoing maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 5593601003 is determined by the following critical parameters:

• Panel cutout dimensions (0.25" / 6.35mm round)
• Lens form factor (5mm, T-1 3/4 round domed)
• Termination style (wire leads with 6-inch length)
• Lamp color configuration (green and yellow dual-color)
• Current rating (30mA per color)
• Viewing angle (65°)
• Series compatibility (Dialight 559 series)

The substitute part 5593601003F maintains mechanical compatibility through identical panel cutout dimensions, lens size, lens style, and wire lead termination. Both parts operate within the same series and support the same dual-color lamp configuration with equivalent current ratings. Electrical parameter variations exist in forward voltage specifications and millicandela ratings, which reflect design improvements in the active substitute variant.

Parameter Comparison

Engineering Selection Recommendations

The 5593601003F serves as the direct active substitute for the obsolete 5593601003. Both components share identical mechanical interfaces and termination specifications, enabling direct replacement in existing panel cutouts and wire harness configurations.

The substitute part offers improved regulatory compliance through ROHS3 certification, addressing environmental and material restriction requirements applicable to current manufacturing standards. The original part carries RoHS non-compliant status, which may present sourcing and regulatory challenges in new applications.

Forward voltage increases in the substitute (2.1V green, 2.0V yellow versus 1.6V for both colors in the original) require circuit design verification to ensure adequate supply voltage and current-limiting resistor values remain appropriate. Millicandela ratings are reduced in the substitute (14.6mcd green, 9mcd yellow versus 20mcd for both colors), which may impact visibility in high-ambient-light environments. Wavelength shifts are minor and remain within standard color perception ranges for green and yellow indicators.

Selection between these parts depends on regulatory compliance requirements, available supply voltage headroom, and ambient light conditions in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 5593601003F directly replace the 5593601003 in existing equipment?

A: Mechanical and termination compatibility is confirmed. The panel cutout dimensions, lens form factor, and wire lead specifications are identical. Circuit design review is necessary to accommodate the higher forward voltage requirements of the substitute part.

Q: What are the key electrical differences between these parts?

A: The substitute part operates at higher forward voltages (2.1V green, 2.0V yellow) compared to the original (1.6V for both colors). Current ratings remain constant at 30mA per color. Brightness output is reduced in the substitute, with green output at 14.6mcd versus 20mcd and yellow at 9mcd versus 20mcd.

Q: Does the substitute part meet current environmental regulations?

A: The 5593601003F carries ROHS3 compliance certification, meeting current Restriction of Hazardous Substances requirements. The original part is RoHS non-compliant and may not satisfy procurement specifications for new designs or regulated applications.

Q: Are there mechanical modifications required for installation?

A: No mechanical modifications are required. Both parts feature identical 0.25-inch round panel cutouts, 5mm T-1 3/4 lens form factors, and 6-inch wire lead terminations.

Q: How do the wavelength differences affect color perception?

A: Wavelength shifts are minimal (green: 565nm to 568nm; yellow: 583nm to 590nm) and remain within standard color perception ranges. Visual color differentiation between the two parts is negligible in typical indicator applications.

Q: What circuit design considerations apply when substituting this part?

A: Supply voltage must accommodate the higher forward voltage of the substitute. Current-limiting resistor values should be recalculated based on the new voltage specifications to maintain 30mA operation per color. Reduced brightness output may require assessment against ambient light conditions in the target environment.
