LED GRN/YLW DIFFUSED 5MM T/H 5219724F

Part Overview

The Dialight 5219724F is an active, through-hole mounted LED indicator featuring green and yellow color options with diffused lens technology. This dual-color LED is designed for discrete indication applications requiring 2.1V forward voltage operation at 20mA test current. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial environments. Equivalent substitute parts may be required due to inventory availability, regional sourcing constraints, or specific application requirements for alternative optical or electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

The Kingbright WP57GYW qualifies as an equivalent substitute for the Dialight 5219724F based on the following critical parameters:

Substitution Criteria Met:

• Dual-color configuration (Green, Yellow)
• Diffused lens transparency
• Through-hole radial mounting
• 5mm lens diameter (T-1 3/4 package)
• Forward voltage compatibility (2.2V Green, 2.1V Yellow vs. 2.1V Green, 2.1V Red)
• 20mA test current rating
• ROHS3 compliance
• MSL 1 rating
• Radial package type

Parameters Allowing Substitution: The WP57GYW operates within acceptable tolerance ranges for forward voltage (±0.1V variance on green channel) and maintains identical test current specifications. Both parts feature diffused optics suitable for general indication applications. The 60° viewing angle of the substitute provides broader light distribution compared to the 50° specification of the main part, which is acceptable for most indication circuits. The higher millicandela ratings (30mcd Green, 10mcd Yellow) of the substitute represent improved optical performance without creating incompatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Dialight 5219724F and Kingbright WP57GYW are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications. Selection between these parts should be based on:

Dialight 5219724F: Primary choice when exact forward voltage specification of 2.1V across both colors is required, or when the 50° viewing angle is specifically matched to circuit design parameters.

Kingbright WP57GYW: Suitable alternative when higher luminous intensity (30mcd Green, 10mcd Yellow) is acceptable or beneficial for visibility in brighter environments. The 60° viewing angle provides wider light distribution. Forward voltage tolerance of ±0.1V on the green channel remains within typical circuit design margins for LED indicator applications.

Both parts maintain identical test current ratings and MSL classifications, ensuring equivalent thermal and environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the WP57GYW directly replace the 5219724F in existing PCB designs? A: Yes. Both parts feature identical 5mm through-hole radial mounting with matching lead spacing. No PCB modification is required. Forward voltage differences (2.2V vs. 2.1V on green) fall within standard LED circuit design tolerances.

Q: What is the significance of the T-1 3/4 package designation on the WP57GYW? A: T-1 3/4 is the standard industry designation for 5mm diameter through-hole LEDs. This confirms mechanical and electrical compatibility with the 5219724F, which uses the same 5mm form factor.

Q: Does the higher millicandela rating of the WP57GYW affect circuit compatibility? A: No. Higher luminous intensity does not create electrical incompatibility. The 20mA test current remains identical. Applications requiring lower brightness can implement current-limiting resistor adjustments if needed.

Q: Are there wavelength differences between these parts? A: Peak wavelengths are nearly identical (565nm Green for both; 585nm vs. 590nm Yellow). These differences are imperceptible to human vision and do not affect color indication functionality.

Q: What viewing angle difference should I consider? A: The WP57GYW provides 60° viewing angle versus 50° for the 5219724F. This 10° difference results in broader light distribution, which is beneficial for general indication applications and does not create incompatibility.

Q: Are both parts suitable for the same environmental conditions? A: Yes. Both maintain MSL 1 (Unlimited) rating and ROHS3 compliance, ensuring equivalent performance in standard industrial and commercial environments without moisture sensitivity concerns.
