TLUR6400 Red Diffused LED T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The TLUR6400 is a red diffused LED manufactured by Vishay Semiconductor Opto Division, designed for discrete indication applications. This T-1 3/4 through-hole component features a 5mm lens with 630nm dominant wavelength and 15mcd brightness rating. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring compatible red LED indication functionality.

Engineering Selection Recommendations

Primary Recommendation: TLUR5400 (Vishay)

TLUR5400 is the preferred substitute. Manufactured by the same supplier as the original TLUR6400, this part maintains identical electrical specifications (2V forward voltage, 10mA test current, 15mcd brightness, 630nm dominant wavelength, 60° viewing angle). The part is currently in active production status with 3704 units in stock. Height difference (12.80mm vs. 9.10mm) requires mechanical clearance verification in the application. RoHS3 compliance and MSL-1 rating match the original specification.

Secondary Recommendations for Active Alternatives:

HLMP-D101 / HLMP-D101-J0002 (Broadcom)

These parts provide superior brightness (70mcd vs. 15mcd) with compatible wavelength (637nm) and viewing angle (65°). Forward voltage is lower (1.8V vs. 2V), requiring circuit verification. Current rating is 20mA at test. Both bulk and tape & reel packaging options are available. Extensive inventory (32743 bulk units, 706 TR units) ensures supply continuity.

5219672F (Dialight Series 521)

This part offers 60mcd brightness with matching 60° viewing angle and 2V forward voltage. Wavelength (623nm) and test current (20mA) are within acceptable ranges. Height (8.21mm) is closest to original specification. Active production status with 2314 units in stock.

Everlight Alternatives (1383SDRD/S530-A3, 333-2SDRD/S530-A3)

Both Everlight parts maintain 2V forward voltage and 639nm wavelength compatibility. Higher brightness ratings (320mcd and 160mcd respectively) suit applications requiring increased luminous intensity. Narrower viewing angle (30° vs. 60°) may limit directional applications. Test current is 20mA. Active production with adequate inventory.

Not Recommended:

HLMP-3600-D00B2 operates at 5V, incompatible with 2V circuit designs. HLMP-D150 is obsolete with incomplete specifications. 5219240F and 5219480F lack sufficient electrical parameter documentation for reliable substitution.

Frequently Asked Questions (FAQ)

Q: Can TLUR5400 replace TLUR6400 directly without circuit modification?

A: Electrical specifications are identical (2V, 10mA, 15mcd, 630nm, 60°), enabling direct substitution. Mechanical height difference (12.80mm vs. 9.10mm) requires verification that PCB clearance and mechanical mounting accommodate the increased length.

Q: What is the brightness difference between TLUR6400 and HLMP-D101?

A: HLMP-D101 provides 70mcd brightness compared to TLUR6400's 15mcd, representing a 4.7× increase in luminous intensity. This higher brightness may be visible in the application and could require resistor adjustment to maintain consistent indicator appearance.

Q: Are Everlight parts suitable for 2V applications?

A: Yes. Both 1383SDRD/S530-A3 and 333-2SDRD/S530-A3 are rated for 2V forward voltage. However, test current is specified at 20mA rather than 10mA. Circuit design must accommodate this higher current requirement.

Q: What is the viewing angle impact when substituting with Everlight parts?

A: Everlight parts specify 30° viewing angle versus TLUR6400's 60°. This narrower angle concentrates light output in a smaller cone, suitable for applications requiring directional indication but unsuitable for wide-angle visibility requirements.

Q: Can HLMP-D101 operate in a 2V circuit designed for TLUR6400?

A: HLMP-D101 has 1.8V forward voltage, lower than the original 2V specification. In a fixed 2V circuit, this part will draw higher current (approximately 20mA vs. 10mA). Series resistor adjustment is required to maintain proper current limiting and prevent premature LED failure.

Q: What packaging options are available for active substitutes?

A: TLUR5400 is supplied in bulk packaging. HLMP-D101 is available in both bulk and tape & reel (TR) formats. Dialight 5219672F is supplied in bulk. Everlight parts are supplied in bulk. Packaging selection depends on production volume and assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts carry RoHS3 compliance certification, matching the original TLUR6400 specification. Moisture Sensitivity Level is MSL-1 (Unlimited) for all active alternatives.

Q: Which substitute offers the closest physical and electrical match?

A: TLUR5400 provides the closest match with identical electrical specifications and same manufacturer. Only the physical height differs (12.80mm vs. 9.10mm). This part is the recommended first choice for direct replacement applications.
