MV5052 Red LED T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV5052 is a red LED indicator from onsemi, configured as a T-1 3/4 through-hole component with a clear domed lens. Specified at 2.2V forward voltage and 0.7mcd brightness, this part is classified as obsolete. Due to its discontinued status, equivalent substitute parts are necessary for ongoing design support, maintenance, and production continuity. Substitute selection must maintain compatibility with the original electrical characteristics and mechanical form factor.

Substitute Part Grouping Explanation

Substitution of the MV5052 is determined by the following critical parameters:

Primary Compatibility Criteria:

Lens size: 5mm, T-1 3/4 form factor
Mounting type: Through hole, radial configuration
Color: Red
Forward voltage range: 1.9V to 2.2V (allows operation in similar circuit topologies)
Current rating: 10mA to 20mA test current
Viewing angle: 60° to 72° (acceptable for indication applications)
Wavelength - Peak: 626nm to 660nm (red spectrum)

Secondary Considerations:

Lens transparency: Clear or diffused (both acceptable for indication purposes)
Millicandela rating: 0.7mcd to 30mcd (brightness variation acceptable depending on application requirements)
Height variation: ±1.5mm from original 8.89mm specification
Product status: Active preferred for long-term availability

Substitute parts meeting these criteria are functionally compatible with the MV5052 in standard LED indication circuits. Diffused lens variants are included as they maintain the same mechanical interface and electrical operation while offering alternative optical characteristics.

Engineering Selection Recommendations

Tier 1 - Closest Electrical Match: HLMP-3301 series (Broadcom) parts are the primary substitutes. These components operate at 1.9V forward voltage with 10mA test current, maintaining compatibility with circuits designed for the MV5052. The HLMP-3301 base part and its variants (HLMP-3301-D0000, HLMP-3301-D0001, HLMP-3301-D0002, HLMP-3301-F0002) are all active products with ROHS3 compliance, ensuring long-term availability and regulatory compliance. Height variation of 9.19mm versus 8.89mm is within acceptable mechanical tolerance for through-hole applications.

Tier 2 - Voltage-Matched Alternatives: The 151051RS11000 (Würth Elektronik) operates at 2.1V forward voltage, closely matching the MV5052 specification of 2.2V. This part maintains the 20mA test current and offers ROHS3 compliance. The 4.90mm lens diameter is slightly smaller than the standard 5mm T-1 3/4 form factor but remains mechanically compatible in most through-hole PCB layouts.

Tier 3 - Voltage-Regulated Applications: The 4302H1-5V and 4302H1-12V (VCC) are suitable only for applications where the LED is driven through a current-limiting resistor or voltage regulator. These parts operate at higher forward voltages (5V and 12V respectively) and are not direct pin-for-pin replacements without circuit modification.

Compliance and Availability: All recommended substitutes carry ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements. Broadcom HLMP-3301 variants show the highest inventory levels (945 to 34,884 units), ensuring supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the MV5052 be directly replaced with HLMP-3301 without circuit modification? A: Yes. Both parts operate at compatible forward voltages (2.2V vs. 1.9V) and test currents (20mA vs. 10mA). The HLMP-3301 can be used in circuits designed for the MV5052 with standard current-limiting resistor sizing. The 0.3V difference in forward voltage is within normal design tolerance for LED indication circuits.

Q: What is the difference between HLMP-3301 variants (D0000, D0001, D0002, F0002)? A: These variants differ in packaging format and millicandela rating. D0000 and D0002 are available in bulk and cut tape respectively, both rated at 2.1mcd. D0001 is tape and reel packaged at 2.1mcd. F0002 is cut tape packaged at 5.4mcd brightness. All share identical electrical specifications (1.9V, 10mA, 60° viewing angle, 635nm peak wavelength).

Q: Why is the 151051RS11000 listed as a substitute if its lens diameter is 4.90mm instead of 5mm? A: The 4.90mm diameter is within the tolerance range for T-1 3/4 form factor components and maintains mechanical compatibility with standard through-hole PCB layouts. The 0.1mm difference does not affect electrical performance or typical mounting applications.

Q: Are the VCC 4302H1 series (5V and 12V) direct replacements? A: No. These parts operate at significantly higher forward voltages and require circuit redesign with appropriate current-limiting resistors. They are suitable only for applications where the LED is powered from 5V or 12V supply rails with series resistance.

Q: What is the impact of lens transparency (clear vs. diffused) on substitution? A: The MV5052 features a clear lens, while most substitutes use diffused lenses. Both provide red indication functionality. Clear lenses produce a more focused light beam, while diffused lenses scatter light over a wider area. Selection depends on application requirements for light distribution and viewing angle.

Q: Which substitute offers the best long-term availability? A: The Broadcom HLMP-3301 series, particularly HLMP-3301-D0000 with 34,884 units in stock, offers the highest inventory levels and active product status, ensuring sustained availability for production and maintenance applications.

Q: Is there a brightness difference between the MV5052 (0.7mcd) and substitutes? A: Yes. Substitutes range from 2.1mcd to 30mcd. The HLMP-3301 variants at 2.1mcd to 5.4mcd are closer to the original specification. Higher brightness substitutes (151051RS11000 at 30mcd) may require circuit adjustment if brightness consistency is critical to the application.
