TLUR4400 Equivalent & Substitute Parts

Part Overview

The TLUR4400 is a red diffused T-1 through-hole LED manufactured by Vishay Semiconductor Opto Division. This discrete indicator LED operates at 2V forward voltage with a 15mcd brightness rating and 630nm dominant wavelength. The component is ROHS3 compliant and currently in active production status with 5400 units in stock. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and packaging specifications align with the original design requirements.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility with the TLUR4400:

Parametric Equivalents maintain identical or near-identical electrical characteristics within the same manufacturer family. These parts share the same forward voltage (2V), test current (10mA), lens size (3mm T-1), viewing angle (60°), and mounting type (through hole). Wavelength variations remain within the red spectrum (619nm to 640nm dominant wavelength). Height specifications are consistent at 6.10mm maximum.

Manufacturer Recommended Alternatives are cross-manufacturer substitutes from Broadcom Limited that provide functional equivalence through different electrical specifications. These parts operate at different forward voltages (1.7V to 12V) and test currents (1mA to 13mA), requiring circuit redesign for direct substitution. All alternatives maintain the same lens size (3mm T-1), diffused transparency, through-hole mounting, and red color specification.

Key parameters determining substitution eligibility:

Lens size and type (3mm T-1 diffused)
Color (red)
Mounting type (through hole radial)
Viewing angle compatibility (50° to 60°)
Height envelope (6.10mm to 6.35mm)
RoHS3 compliance and MSL rating

Engineering Selection Recommendations

Direct Parametric Substitutes (No Circuit Modification Required)

TLHR4405, TLUR4401, and TLLK4401 are Vishay products within the same manufacturer family and maintain active production status with ROHS3 compliance. TLUR4401 provides the closest electrical match with identical 2V forward voltage and 10mA test current, differing only in brightness (18mcd versus 15mcd). TLHR4405 operates at identical electrical specifications with a wavelength shift to 619nm, acceptable within red LED specifications. TLLK4401 requires lower operating current (2mA versus 10mA) and reduced forward voltage (1.8V), suitable for low-power applications with compatible circuit design.

Cross-Manufacturer Alternatives (Circuit Redesign Required)

Broadcom HLMP series parts require circuit modification due to different electrical specifications. HLMP-K101 offers higher brightness (45mcd) at 1.8V forward voltage with 20mA test current, suitable for applications requiring increased luminous intensity. HLMP-1700 and HLMP-1700-B0002 operate at 1.7V with minimal current draw (2mA), appropriate for battery-powered or low-power indicator applications. HLMP-K150 and HLMP-K150-C0002 provide ultra-low current operation (1mA) at 1.7V forward voltage for minimal power consumption designs. HLMP-1600 and HLMP-1601 operate at higher voltages (5V and 12V respectively) for direct integration into standard logic-level circuits.

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (unlimited), and active product status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can TLHR4405 replace TLUR4400 without circuit modification?

A: Yes. TLHR4405 maintains identical forward voltage (2V), test current (10mA), lens size (3mm T-1), and mounting type. The wavelength shift from 630nm to 619nm remains within acceptable red LED specifications and produces no visible color difference in typical indicator applications.

Q: What is the primary difference between Vishay and Broadcom substitute options?

A: Vishay parametric equivalents (TLHR4405, TLUR4401, TLLK4401) operate at similar electrical specifications to the TLUR4400, requiring minimal or no circuit redesign. Broadcom alternatives operate at different forward voltages and currents, requiring circuit modification including resistor value changes or voltage supply adjustments.

Q: Is HLMP-K101 suitable as a direct replacement for TLUR4400?

A: HLMP-K101 is mechanically compatible but requires circuit redesign. It operates at 1.8V forward voltage with 20mA test current versus the TLUR4400's 2V and 10mA specifications. The significantly higher brightness (45mcd versus 15mcd) may require optical diffusion or reduced current limiting to match original application intensity.

Q: What packaging options are available for Broadcom substitutes?

A: HLMP-1700-B0002 and HLMP-K150-C0002 are supplied in Cut Tape (CT) packaging for automated assembly. Standard Broadcom parts (HLMP-1700, HLMP-K101, HLMP-K150) are supplied in Bulk packaging. Vishay parts are supplied in Bulk packaging. Packaging selection depends on assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (unlimited), meeting regulatory requirements for electronic component applications.

Q: Which substitute offers the lowest power consumption?

A: HLMP-K150 and HLMP-K150-C0002 operate at 1.7V forward voltage with 1mA test current, providing the lowest power consumption option. These parts are suitable for battery-powered applications or designs requiring minimal current draw.

Q: Can TLLK4401 replace TLUR4400 in existing circuit boards?

A: TLLK4401 is mechanically compatible but operates at reduced forward voltage (1.8V versus 2V) and current (2mA versus 10mA). Existing current-limiting resistors must be recalculated to maintain proper LED operation. The higher brightness (17mcd versus 15mcd) may require adjustment for consistent visual appearance.
