Dialight 5219484F LED GREEN/RED DIFFUSED 3MM T/H Equivalent & Substitute Parts

Part Overview

The Dialight 5219484F is a through-hole mounted bicolor LED indicator featuring green and red diffused lenses in a 3mm round package with domed top. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part serves discrete radial LED indication applications requiring dual-color status signaling in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5219484F is determined by strict alignment with the following critical parameters:

• Bicolor configuration (Green and Red)
• Diffused lens transparency
• 3.00mm diameter lens size
• Round lens style with domed top
• Through-hole radial mounting
• 20mA test current specification for both colors
• Radial package configuration

The Marktech Optoelectronics MT2030-HRG-A satisfies all mandatory substitution criteria. This part maintains identical mechanical form factor, lens specifications, and electrical test current ratings. The substitute is classified as active product status with full RoHS compliance and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Marktech Optoelectronics MT2030-HRG-A is the qualified substitute for the obsolete Dialight 5219484F. Selection is based on:

• Complete mechanical and electrical parameter alignment with the original part
• Active product status ensuring long-term availability and supply chain continuity
• RoHS compliance certification meeting current environmental and regulatory requirements
• REACH unaffected status matching the original part's compliance profile
• Identical test current specifications eliminating circuit redesign requirements

The substitute part maintains form factor compatibility with existing through-hole PCB layouts and does not require modifications to mounting or electrical interfaces.

Frequently Asked Questions (FAQ)

Q: Can the MT2030-HRG-A be used as a direct replacement without PCB modifications?

A: Yes. The MT2030-HRG-A maintains identical lens size (3.00mm), lens style (round with domed top), mounting type (through-hole radial), and test current specifications (20mA for both colors). No PCB layout changes are required.

Q: What is the significance of the diffused lens specification?

A: The diffused lens transparency is a critical parameter for this application. It determines light distribution characteristics and viewing angle. Only substitutes with diffused lens transparency maintain equivalent optical performance.

Q: Are there differences in forward voltage between the original and substitute?

A: The original Dialight 5219484F does not specify forward voltage. The Marktech MT2030-HRG-A specifies 2.1V for both green and red. This specification should be verified against circuit design requirements to ensure compatibility with existing current-limiting resistor values.

Q: What does the MSL rating difference mean?

A: The original part carries MSL 1 (Unlimited), while the substitute carries MSL 2 (1 Year). MSL 2 requires storage in controlled humidity conditions for one year. This affects component handling and storage procedures but does not impact functional performance.

Q: Is the substitute RoHS compliant?

A: Yes. The Marktech MT2030-HRG-A is RoHS compliant. The original Dialight part does not specify RoHS status. Both parts are REACH unaffected.
