Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Color: Red (all substitutes must be red)
Mounting Type: Through Hole (all substitutes must be through-hole)
Lens Transparency: Diffused (all substitutes must be diffused)
Package / Case: Radial (all substitutes must be radial)
Voltage - Forward (Vf): 2V nominal (acceptable range: 1.8V to 2.1V)
Current - Test: 10mA nominal (acceptable range: 10mA to 20mA)
Lens Size: 5mm, T-1 3/4 form factor (acceptable: 4.75mm to 5mm diameter)

Parametric equivalents (TLUR5400, TLUR5401) meet all critical parameters with identical electrical and mechanical specifications. Manufacturer-recommended substitutes from Dialight, Broadcom, and Lite-On meet the core substitution criteria with minor variations in brightness, wavelength, or test current that remain functionally compatible within standard indicator LED applications.

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitutes)

TLUR5400 and TLUR5401 are parametric equivalents manufactured by Vishay. Both parts maintain identical electrical specifications (2V, 10mA), mechanical form factor (5mm T-1 3/4), and compliance certifications (ROHS3). These parts are interchangeable with TLHR5405 without circuit modification.

Manufacturer-Recommended Substitutes

Broadcom HLMP-D101 and Lite-On LTL-4223 are Active status parts that meet core substitution criteria. HLMP-D101 operates at 1.8V forward voltage with higher brightness (70mcd) and requires 20mA test current. LTL-4223 matches the 2V/10mA electrical profile with comparable brightness (19mcd) and identical form factor. Both are ROHS3 compliant.

Dialight 5219672F and Lite-On LTL-10223W provide higher brightness options (60mcd) at 2V/10mA or 2V/20mA respectively, suitable for applications requiring increased luminous intensity.

Parts Not Recommended

HLMP-D150 (onsemi) is Obsolete status and should not be selected for new designs. HLMP-3600-D00B2 (Broadcom) operates at 5V and is a right-angle mount configuration, incompatible with standard radial through-hole applications. Dialight 5219240F lacks complete electrical specifications and provides significantly lower brightness (6.3mcd).

Frequently Asked Questions (FAQ)

Q: Can TLUR5400 or TLUR5401 be used as direct replacements for TLHR5405?

A: Yes. Both TLUR5400 and TLUR5401 are parametric equivalents with identical forward voltage (2V), test current (10mA), lens size (5mm T-1 3/4), and mounting type (through-hole radial). No circuit modifications are required.

Q: What is the difference between TLHR5405 and HLMP-D101?

A: HLMP-D101 operates at 1.8V forward voltage (versus 2V) and requires 20mA test current (versus 10mA). HLMP-D101 provides higher brightness (70mcd versus 14mcd). Circuit design must accommodate the lower forward voltage and higher current draw.

Q: Can I use LTL-10223W or 5219672F for higher brightness applications?

A: Yes. Both parts provide 60mcd brightness compared to TLHR5405 at 14mcd. LTL-10223W maintains 2V/10mA electrical specifications. 5219672F requires 20mA test current. Verify circuit current capacity before selection.

Q: Why is HLMP-D150 not recommended?

A: HLMP-D150 is Obsolete status. Active alternatives with complete specifications are available. New designs should not use obsolete components.

Q: Are all substitute parts ROHS3 compliant?

A: All Active status substitute parts listed are ROHS3 compliant. HLMP-D150 (Obsolete) compliance status is not specified and should not be used.

Q: What is the viewing angle range across substitutes?

A: Viewing angles range from 36° (LTL-4223) to 65° (HLMP-D101). TLHR5405 specifies 60°. Applications requiring specific viewing angle characteristics should verify the selected substitute meets optical requirements.

Q: Can I substitute based on brightness alone?

A: No. Substitution requires matching multiple parameters: forward voltage, test current, lens size, mounting type, and form factor. Brightness variation is acceptable only if circuit design accommodates the electrical differences.
