Key Parameters

Substitute Part Grouping Explanation

The substitute part 5592301027F qualifies as an equivalent based on the following critical parameters:

Mechanical compatibility is established through identical panel cutout dimensions (0.25" / 6.35mm round), lens size (5mm, T-1 3/4), lens style (round with domed top), and termination configuration (wire leads - 14" / 355.60mm). These parameters ensure direct physical interchangeability within the panel assembly.

Optical compatibility is maintained through matching wavelength peak (585nm), viewing angle (50°), and lens transparency (diffused). Both parts deliver yellow light output with identical optical characteristics.

Electrical parameters differ within acceptable substitution tolerances: the substitute operates at 1.9V typical forward voltage versus 2.2V for the original, with maximum current of 20mA versus 25mA. These variations remain within standard LED circuit design margins and do not preclude substitution in typical applications.

Environmental and regulatory compliance is equivalent: both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

The 5592301027F is the active equivalent for the obsolete 5595301027F. Selection of the substitute part is supported by:

Product status transition: The substitute is active production, ensuring long-term availability and supply chain continuity compared to the obsolete original.

Regulatory compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and hazardous substance directives.

Mechanical interchangeability: Identical panel cutout dimensions, lens form factor, and wire lead termination enable direct physical replacement without panel redesign.

Optical performance: Matching wavelength, viewing angle, and diffused lens transparency preserve the visual indication function.

Electrical parameter variance: The 0.3V reduction in forward voltage and 5mA reduction in maximum current represent standard LED manufacturing variation and do not compromise circuit operation in typical indicator applications with series current-limiting resistors.

Frequently Asked Questions (FAQ)

Q: Can the 5592301027F directly replace the 5595301027F in existing assemblies?

A: Yes. Mechanical compatibility is confirmed through identical panel cutout dimensions (0.25" round), lens size (5mm T-1 3/4), and wire lead termination (14" length). Physical installation requires no modification.

Q: What is the significance of the lens color difference (Yellow vs. Blue)?

A: The lens color designation reflects the physical lens material. Both parts emit yellow light at 585nm peak wavelength. The lens color difference does not affect the optical output or visual indication function.

Q: How do the electrical parameter differences affect circuit design?

A: The substitute operates at 1.9V typical forward voltage versus 2.2V for the original, with 20mA maximum current versus 25mA. In typical applications using series current-limiting resistors, these variations fall within standard LED circuit design tolerances and do not require circuit modification.

Q: Are there any compliance or environmental concerns with substitution?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical (MSL 1, unlimited). Substitution maintains full regulatory compliance.

Q: What is the brightness difference between the two parts?

A: The substitute has a millicandela rating of 29mcd versus 34mcd for the original. This represents approximately 15% lower luminous intensity. In applications where brightness is critical, circuit design adjustments may be necessary.

Q: Is the 5592301027F available in the same packaging as the original?

A: Yes. Both parts are supplied in bulk packaging, consistent with standard LED panel indicator procurement.
