Dialight 5502205 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5502205 is a 5mm green LED circuit board indicator with right-angle through-hole mounting, rated at 2.1V and 10mA. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates as a single green diffused indicator with a 563nm peak wavelength and 10mcd brightness rating, suitable for PCB-mounted signaling applications requiring low-power consumption and compact form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5502205 is determined by the following critical parameters:

Direct Substitutes (Dialight Series 550): Parts 5502205F, 5502208010F, and 5502212F maintain identical electrical specifications (2.1V, 10mA, 563nm wavelength, 10mcd brightness) and mechanical compatibility (5mm T-1 3/4 through-hole right-angle mounting). These parts are active products with ROHS3 compliance, providing direct functional equivalence with improved availability.

Similar Substitutes (Alternative Manufacturers): Parts SSF-LXH400GD-01 (Lumex) and WP73EK/GDA (Kingbright) operate within compatible voltage and mounting parameters but differ in configuration, current rating, brightness, and lens specifications. These parts are classified as similar rather than direct substitutes due to parameter variations.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Recommended for Obsolete Part Replacement):

Parts 5502205F, 5502208010F, and 5502212F are active Dialight Series 550 products with identical electrical and mechanical specifications to the obsolete 5502205. All three direct substitutes maintain ROHS3 compliance and unlimited moisture sensitivity rating. Selection among these three direct substitutes should be based on packaging requirements and inventory availability. Part 5502205F is available in bulk packaging with 2338 units in stock. Parts 5502208010F and 5502212F are also available in bulk with 1078 and 1186 units respectively.

Alternative Substitution (When Direct Substitutes Unavailable):

Parts SSF-LXH400GD-01 and WP73EK/GDA operate within compatible voltage and mounting specifications but introduce parameter deviations. SSF-LXH400GD-01 is a 4-wide configuration with doubled current (20mA) and brightness (20mcd), requiring circuit redesign for single-indicator applications. WP73EK/GDA is a single-configuration part with increased current (25mA), brightness (30mcd), and reduced lens size (4.80mm vs. 5mm), also requiring circuit modification. Both alternative parts maintain ROHS3 compliance and unlimited moisture sensitivity.

Frequently Asked Questions (FAQ)

Q: Can 5502205F directly replace the obsolete 5502205 without circuit modification?

A: Yes. Part 5502205F maintains identical voltage (2.1V), current (10mA), wavelength (563nm), and brightness (10mcd) specifications. Through-hole right-angle mounting is identical. No circuit redesign is required.

Q: What is the difference between 5502205F, 5502208010F, and 5502212F?

A: All three parts share identical electrical ratings (2.1V, 10mA, 563nm, 10mcd) and mounting type (through-hole right-angle). Part 5502205F does not specify lens style or size. Parts 5502208010F and 5502212F both specify round domed-top 5mm T-1 3/4 lens style. Selection should be based on packaging format and inventory availability.

Q: Can SSF-LXH400GD-01 or WP73EK/GDA replace the 5502205 in existing designs?

A: These parts are not direct substitutes. SSF-LXH400GD-01 is a 4-wide configuration requiring different PCB layout. WP73EK/GDA has higher current (25mA) and brightness (30mcd) ratings with a smaller lens diameter (4.80mm). Both require circuit redesign and are classified as similar alternatives only.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts (5502205F, 5502208010F, 5502212F, SSF-LXH400GD-01, WP73EK/GDA) are ROHS3 compliant. The original 5502205 is listed as REACH Unaffected.

Q: What is the viewing angle difference between the main part and alternatives?

A: The 5502205 and all Dialight direct substitutes have a 65° viewing angle. Lumex SSF-LXH400GD-01 and Kingbright WP73EK/GDA both have 60° viewing angles, representing a 5° reduction in light distribution width.

Q: Are packaging differences significant for substitution?

A: The original 5502205 packaging is listed as "-" (unspecified). Direct substitutes 5502205F, 5502208010F, and 5502212F are available in bulk packaging. Packaging format does not affect electrical or mechanical compatibility for through-hole PCB mounting applications.
