TLHO4200 Orange LED T-1 Through Hole Equivalent & Substitute Parts

Part Overview

The TLHO4200 is an orange 605nm LED indication component manufactured by Vishay Semiconductor Opto Division. This T-1 through-hole radial LED operates at 2.4V forward voltage with a 10mA test current and delivers 10 millicandela brightness. The component is Active status and ROHS3 compliant, making it suitable for standard indication applications requiring discrete LED solutions.

Substitute parts are necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives meeting equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the TLHO4200 is determined by the following criteria:

Primary Substitution Criteria (Orange Color Match):

Color: Orange
Wavelength - Dominant: 605nm or adjacent orange spectrum (600-610nm)
Mounting Type: Through Hole
Package / Case: Radial
Lens Size: 3mm, T-1
Lens Style: Round with Domed Top
Lens Transparency: Clear

Secondary Compatibility Parameters:

Voltage - Forward (Vf): 2.0V to 2.4V range
Current - Test: 10mA to 20mA range
Viewing Angle: 30° to 50° range
Height (Max): 4.60mm to 6.35mm range

Parts meeting the primary criteria are direct orange LED substitutes. Parts with yellow color or significantly different wavelengths are listed as cross-reference alternatives but require circuit design verification for color-specific applications.

Engineering Selection Recommendations

Direct Orange Substitutes (Primary Selection):

HLMP-Y402-G0000, WP132XNT, and WP710A10NT are qualified orange LED substitutes for the TLHO4200. All three maintain orange wavelength specifications (602-605nm), T-1 through-hole radial packaging, and ROHS3 compliance. HLMP-Y402-G0000 offers the closest wavelength match at 605nm dominant with 29mcd brightness. WP710A10NT provides 30mcd brightness with 602nm wavelength and 34° viewing angle. WP132XNT delivers 20mcd at 602nm with a wider 50° viewing angle.

Yellow LED Cross-References (Application-Dependent):

Yellow LED alternatives including HLMP-1420, HLMP-1421, LTL-4252N, SLR-332YC3F, SSL-LX3044YT, WP710A10YT, and 5219431F are listed as cross-reference options. These components share identical through-hole radial packaging, T-1 form factor, and ROHS3 compliance but differ in color specification. Selection of yellow alternatives requires confirmation that the application does not mandate orange wavelength for color-specific indication purposes.

All substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with the original TLHO4200 specification.

Frequently Asked Questions (FAQ)

Q: Can HLMP-Y402-G0000 directly replace TLHO4200 in all applications?

A: HLMP-Y402-G0000 is a direct orange LED substitute matching the 605nm wavelength specification. Both components share T-1 through-hole radial packaging and ROHS3 compliance. The primary difference is forward voltage (2.1V vs. 2.4V) and test current (20mA vs. 10mA). Circuit design must accommodate these electrical parameter differences.

Q: What is the difference between orange and yellow LED substitutes?

A: Orange LEDs (TLHO4200, HLMP-Y402-G0000, WP132XNT, WP710A10NT) operate in the 602-605nm wavelength range. Yellow LEDs (HLMP-1420, LTL-4252N, SSL-LX3044YT, WP710A10YT) operate in the 583-590nm wavelength range. Color-specific indication applications require matching the original wavelength specification. Yellow alternatives are listed as cross-references only.

Q: Are all substitute parts compatible with the same PCB footprint?

A: All listed substitutes maintain T-1 through-hole radial packaging with 3mm lens diameter and round domed top lens style. Height variations range from 4.60mm to 6.35mm. PCB through-hole spacing and lead bend radius compatibility should be verified for components with height differences exceeding 1mm from the original 6.10mm specification.

Q: Which substitute offers the highest brightness?

A: SSL-LX3044YT delivers 90mcd brightness, the highest among all listed alternatives. This yellow LED operates at 2.1V forward voltage with 20mA test current and 30° viewing angle. Selection requires confirmation that yellow wavelength is acceptable for the application.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). REACH status varies: most parts are REACH Unaffected; LTL-4252N is REACH Affected. All components carry EAR99 ECCN classification and 8541.41.0000 HTSUS code.

Q: Can WP710A10NT replace TLHO4200 if forward voltage differs?

A: WP710A10NT operates at 2.05V forward voltage compared to TLHO4200 at 2.4V. This 0.35V difference requires circuit design verification. Current-limiting resistor values and power supply specifications must be recalculated to ensure proper LED operation and brightness consistency.
