TLHB5401 Equivalent & Substitute Parts

Part Overview

The TLHB5401 is a blue diffused 5mm through-hole LED manufactured by Vishay Semiconductor Opto Division, designed for indication applications. This part operates at a forward voltage of 3.9V with a test current of 20mA and delivers 21 millicandela at a dominant wavelength of 466nm. The product is Active status and fully compliant with RoHS3 and REACH regulations. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit component flexibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLHB5401 is determined by the following critical parameters:

• Color: Blue
• Lens Transparency: Diffused
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Package / Case: Radial
• Viewing Angle: 60°
• Voltage - Forward (Vf) (Typ): 3.9V ±0.6V operational tolerance
• Current - Test: 20mA
• Wavelength - Dominant: 466nm ±5nm acceptable range
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The WP7083QBD/G from Kingbright meets the core mechanical and optical specifications for substitution. Both parts share identical lens size, mounting configuration, viewing angle, and compliance certifications. Electrical parameters remain within acceptable operational ranges for indication applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TLHB5401 and WP7083QBD/G are Active status products with full RoHS3 and REACH compliance. Selection between these parts is based on the following provided specifications:

The TLHB5401 operates at 3.9V forward voltage with 21mcd luminous intensity and a maximum height of 12.80mm.

The WP7083QBD/G operates at 3.3V forward voltage with 360mcd luminous intensity and a maximum height of 8.60mm.

Both parts maintain identical mechanical form factors (5mm T-1 3/4 through-hole radial package), viewing angles (60°), and test current (20mA). Dominant wavelengths are within 1nm of each other (466nm vs 465nm). Circuit design must account for the 0.6V forward voltage difference and the 339mcd luminous intensity difference when selecting between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can the WP7083QBD/G directly replace the TLHB5401 in existing designs?

A: Mechanical compatibility is confirmed. Both parts use identical 5mm T-1 3/4 through-hole radial packages with 60° viewing angles. However, the forward voltage differs by 0.6V (3.9V vs 3.3V) and luminous intensity differs by 339mcd (21mcd vs 360mcd). Circuit design must accommodate these electrical differences.

Q: What are the compliance differences between these parts?

A: Both parts are RoHS3 Compliant and REACH Unaffected. No compliance differentiation exists between the TLHB5401 and WP7083QBD/G.

Q: How do the wavelength specifications compare?

A: The TLHB5401 has a dominant wavelength of 466nm, while the WP7083QBD/G has a dominant wavelength of 465nm. This 1nm difference is within typical blue LED manufacturing tolerances.

Q: What is the height difference impact?

A: The TLHB5401 has a maximum height of 12.80mm, while the WP7083QBD/G has a maximum height of 8.60mm. The substitute part is 4.20mm shorter, which may affect PCB layout and mechanical clearance considerations.

Q: Are both parts suitable for the same test current?

A: Yes. Both parts are specified for 20mA test current operation.
