MR5760 LED Red Diffused T-1 T/H Equivalent & Substitute Parts

Part Overview

The MR5760 is a red diffused LED indicator from onsemi, designed for through-hole mounting in 3mm T-1 form factor applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance requirements. The MR5760 operates at 5V forward voltage with a 10mA test current and delivers 4mcd luminous intensity with a 60° viewing angle. Substitutes must maintain compatibility with 5V circuit designs while preserving the T-1 through-hole mounting configuration and diffused red lens characteristics.

Substitute Part Grouping Explanation

Substitution logic for the MR5760 is determined by the following critical parameters:

Primary Compatibility Criteria:

Forward voltage (Vf): 5V nominal operation
Lens size and form factor: 3mm T-1 through-hole radial package
Lens transparency: Diffused red
Mounting type: Through hole radial configuration
Wavelength range: 635nm peak (red spectrum)

Secondary Compatibility Factors:

Test current: 10mA baseline
Viewing angle: 60° preferred for equivalent performance
Millicandela rating: 4mcd baseline (lower ratings acceptable for indicator applications)
Height: Maximum 6.35mm to fit standard PCB clearances

Substitutes are grouped into two categories:

Category A - Direct 5V Equivalents: Parts operating at 5V forward voltage with T-1 form factor, maintaining circuit compatibility without modification.

Category B - Lower Voltage Alternatives: Parts operating below 5V (1.7V to 2.2V) that require series resistor recalculation but maintain mechanical and optical compatibility.

Engineering Selection Recommendations

For Direct 5V Circuit Replacement (No Resistor Recalculation Required):

HLMP-1600 from Broadcom Limited is the primary equivalent for the MR5760. Both operate at 5V forward voltage with 10mA test current and 60° viewing angle. The HLMP-1600 is active production status and ROHS3 compliant, addressing the obsolescence and compliance limitations of the MR5760. The luminous intensity is lower (2.1mcd vs 4mcd), but this is acceptable for standard indicator applications where the MR5760's 4mcd was not a critical design requirement.

HLMP-1600-D00A1 and HLMP-1600-D00A2 are right-angle variants of the HLMP-1600 base series, maintaining identical electrical specifications but offering alternative mounting geometry for circuit board indicator applications.

For Lower Voltage Circuit Designs (Requires Resistor Recalculation):

HLMP-1700 from Broadcom Limited operates at 1.7V forward voltage and is suitable for low-voltage indicator circuits. This part maintains the T-1 form factor and through-hole radial package. Circuit design must account for the reduced forward voltage and test current (2mA vs 10mA).

HLMP-1301-G00FG from Broadcom Limited operates at 1.9V with 10mA test current and delivers higher luminous intensity (8.6mcd). This part is suitable for applications requiring brighter indication at lower supply voltages.

For Highest Brightness Requirement:

151031SS06000 from Würth Elektronik delivers 35mcd luminous intensity at 2.2V forward voltage, significantly exceeding the MR5760's brightness. This part is ROHS3 compliant and active production status. Circuit design must accommodate the lower forward voltage and higher test current (20mA).

Parts Not Recommended for New Designs:

4300F1LC from Visual Communications Company is classified as "Not For New Designs" and should not be selected for new applications despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can HLMP-1600 replace MR5760 without circuit modification?

A: Yes. Both parts operate at 5V forward voltage with 10mA test current. The HLMP-1600 can be substituted directly into existing MR5760 circuits without resistor or current-limiting changes. The lower millicandela rating (2.1mcd vs 4mcd) is acceptable for standard indicator applications.

Q: What is the difference between HLMP-1600, HLMP-1600-D00A1, and HLMP-1600-D00A2?

A: All three share identical electrical specifications (5V, 10mA, 2.1mcd, 60° viewing angle, 635nm peak wavelength). The base HLMP-1600 is radial through-hole mount. The D00A1 and D00A2 variants are right-angle through-hole mount configurations for circuit board indicator applications where vertical LED orientation is required.

Q: Can lower voltage substitutes like HLMP-1700 or HLMP-1301-G00FG be used in 5V circuits?

A: No, not without circuit modification. These parts operate at 1.7V and 1.9V respectively. Using them in a 5V circuit designed for the MR5760 would result in excessive current and LED failure. Series resistor values must be recalculated based on the new forward voltage and desired operating current.

Q: Why is the MR5760 obsolete?

A: The MR5760 is classified as obsolete by onsemi. Active production alternatives from Broadcom Limited (HLMP series) and other manufacturers provide equivalent or superior performance with current RoHS compliance and ongoing supply availability.

Q: What is the mechanical compatibility of substitute parts?

A: All substitute parts listed maintain the 3mm T-1 through-hole radial package form factor. Height variations exist (5.30mm to 6.35mm maximum), but all fit standard PCB clearances designed for T-1 LEDs. Verify specific PCB layout constraints for applications with tight vertical space limitations.

Q: Are all substitute parts RoHS compliant?

A: The MR5760 is RoHS non-compliant. All recommended active production substitutes (HLMP-1600, HLMP-1700, HLMP-1301-G00FG, 151031SS06000, 3HD-F) are ROHS3 compliant. The 1254-10SURD/S530-A3 from Everlight does not specify RoHS status in available data.

Q: Which substitute offers the brightest indication?

A: The 1254-10SURD/S530-A3 from Everlight Electronics delivers 400mcd, significantly exceeding all other options. However, this part operates at 2V with 20mA test current and has a narrower 30° viewing angle. Circuit design and viewing angle requirements must be evaluated before selection.
