Dialight 5595201809 LED Panel Indicator Green - Equivalent & Substitute Parts

Part Overview

The Dialight 5595201809 is a green LED panel indicator with snap-in mounting, designed for 24-lead panel applications. This component features a diffused green lens with a 50° viewing angle, operating at 2.2V forward voltage and 25mA maximum current. The part is currently classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives within the Dialight 559 series provide direct functional replacement with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Dialight 5595201809 is determined by strict equivalence across the following critical parameters:

• Electrical specifications: Forward voltage (2.2V) and maximum current (25mA)
• Optical characteristics: Green lamp color, diffused lens transparency, 563nm peak wavelength, 34mcd brightness, 50° viewing angle
• Mechanical compatibility: Round panel cutout shape, 0.25" (6.35mm) cutout dimensions, 5mm T-1 3/4 lens size, round domed top lens style
• Environmental ratings: Moisture Sensitivity Level 1 (Unlimited)
• Regulatory compliance: ECCN EAR99, HTSUS 8541.41.0000

All three substitute parts (5595201809F, 5595201810F, 5595201812F) maintain identical electrical, optical, and mechanical parameters. The primary distinction is product status: the original part is obsolete, while all substitutes are active production items with improved RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (5595201809F, 5595201810F, 5595201812F) are direct functional equivalents to the obsolete 5595201809. Selection among these active alternatives should be based on the following factors:

Product Status and Compliance: All substitutes are active production items with ROHS3 compliance, addressing the regulatory limitations of the obsolete original part. This compliance improvement is significant for new designs and applications subject to RoHS directives.

Availability and Inventory: Current stock levels vary among substitutes. 5595201812F maintains the highest inventory (1153 pcs), followed by 5595201810F (997 pcs) and 5595201809F (879 pcs). For high-volume applications, inventory availability may influence selection.

Packaging Consideration: All substitutes are supplied in bulk packaging, consistent with production requirements.

Electrical and Optical Equivalence: All three substitutes maintain identical electrical ratings (2.2V, 25mA), optical characteristics (green diffused, 34mcd, 563nm, 50° viewing angle), and mechanical dimensions (0.25" round cutout, 5mm T-1 3/4 lens). Direct pin-for-pin and form-factor compatibility is assured.

Frequently Asked Questions (FAQ)

Q: Can 5595201809F, 5595201810F, and 5595201812F be used interchangeably with the original 5595201809?

A: Yes. All three substitutes maintain identical electrical specifications (2.2V forward voltage, 25mA maximum current), optical properties (green diffused lens, 34mcd brightness, 563nm wavelength, 50° viewing angle), and mechanical dimensions (0.25" round panel cutout, 5mm T-1 3/4 lens). They are direct functional equivalents suitable for direct replacement in existing designs.

Q: What is the primary difference between the obsolete 5595201809 and the active substitutes?

A: The main difference is product status and regulatory compliance. The original 5595201809 is obsolete and RoHS non-compliant. All three substitutes are active production items with ROHS3 compliance, making them suitable for applications subject to RoHS directives and ensuring long-term supply availability.

Q: Are there any differences in packaging between the substitute parts?

A: All three substitute parts are supplied in bulk packaging. The original 5595201809 packaging specification was not provided in the technical data. Bulk packaging is standard for production applications.

Q: Do the substitute parts have the same moisture sensitivity rating?

A: Yes. All substitute parts maintain Moisture Sensitivity Level 1 (Unlimited), identical to the original part. This indicates no moisture sensitivity constraints for storage or handling.

Q: Which substitute part should be selected for new designs?

A: Any of the three substitutes (5595201809F, 5595201810F, 5595201812F) are suitable for new designs. Selection may be based on inventory availability, supplier preference, or existing supply chain relationships. All are electrically, optically, and mechanically equivalent.

Q: Are the substitute parts subject to the same export regulations as the original?

A: Yes. All parts, including the original and substitutes, are classified under ECCN EAR99 and HTSUS 8541.41.0000, with REACH Unaffected status. Export compliance requirements remain consistent across all variants.
