Substitute Part Grouping Explanation

Substitution of the MV50152 is determined by the following critical parameters:

Lens Size & Mounting: All substitutes maintain 5mm T-1 3/4 through-hole radial package compatibility
Color & Lens Transparency: Red color with clear lens transparency required for direct functional replacement
Electrical Compatibility: Forward voltage (Vf) range 1.6V to 2.1V and test current of 10mA or 20mA acceptable
Brightness & Wavelength: Peak wavelength 630nm to 660nm range; millicandela rating 2mcd to 55mcd depending on application requirements
Viewing Angle: 16° to 50° range accommodates various indication applications
Product Status: Active status substitutes ensure ongoing availability and support

The substitute parts are grouped into two categories: direct electrical equivalents with similar brightness characteristics (HLMP-3351 series, SLR-56 series) and higher-brightness alternatives for applications requiring increased luminous intensity (HLMP-3366, HLMP-3390).

Engineering Selection Recommendations

Primary Substitutes (Closest Electrical Match):

HLMP-3351-D0000 and HLMP-3351-D0002 provide the closest brightness equivalence to MV50152 at 2.1mcd with identical 10mA test current. Forward voltage increases from 1.6V to 1.9V, requiring circuit verification for voltage-sensitive applications. Both parts are ROHS3 compliant and active status. The diffused lens differs from the original clear lens, affecting light distribution characteristics.

Clear Lens Equivalent:

HLMP-3366 maintains clear lens transparency with 13.8mcd brightness, 1.9V forward voltage, and 10mA test current. This part provides higher luminous intensity while preserving optical characteristics. ROHS3 compliant and active status ensure long-term availability.

Low-Current Alternative:

HLMP-D155 operates at 1mA test current with 1.7V forward voltage, closest to the original 1.6V specification. This part suits applications requiring minimal power consumption. Peak wavelength 660nm matches the original specification. ROHS3 compliant and active status.

Higher-Brightness Options:

HLMP-3390 delivers 55mcd brightness for applications requiring increased visibility, though it requires 20mA test current and features a narrower 24° viewing angle. Height increases to 10.90mm, requiring mechanical clearance verification.

SLR-56VC3F and SLR-56VCT32 (Rohm Semiconductor) offer 25mcd brightness at 2V forward voltage with 10mA test current. These parts provide moderate brightness increase with compatible electrical characteristics. ROHS3 compliant and active status.

LTL-4214 (Lite-On Inc.) provides 19mcd brightness at 2.1V forward voltage with clear lens. Narrower 16° viewing angle and 8.60mm height require application-specific evaluation.

All recommended substitutes are ROHS3 compliant and carry active product status, ensuring regulatory compliance and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3351-D0000 directly replace MV50152 without circuit modification?

A: HLMP-3351-D0000 is electrically compatible with forward voltage increase from 1.6V to 1.9V. Circuit verification is required for voltage-sensitive designs. The diffused lens differs from the original clear lens, affecting light distribution. Brightness equivalence at 2.1mcd is maintained.

Q: What is the difference between HLMP-3351-D0000 and HLMP-3351-D0002?

A: Both parts are identical in electrical specifications (1.9V, 10mA, 2.1mcd). The difference is packaging: HLMP-3351-D0000 is supplied in Bulk, while HLMP-3351-D0002 is supplied in Cut Tape (CT). Functional performance is equivalent.

Q: Why does HLMP-3366 have higher brightness than MV50152?

A: HLMP-3366 is rated at 13.8mcd compared to MV50152's 2mcd. Both maintain identical forward voltage (1.9V), test current (10mA), and height (6.35mm). The higher brightness results from improved LED die efficiency. This part suits applications requiring increased visibility while maintaining the same electrical operating point.

Q: Is HLMP-3390 suitable as a direct replacement?

A: HLMP-3390 requires 20mA test current versus MV50152's 10mA, and height increases to 10.90mm versus 6.35mm. Mechanical clearance and power budget must be verified. The 24° viewing angle is narrower than MV50152's 45°. This part is suitable only for applications where increased brightness (55mcd) justifies the design changes.

Q: What are the packaging options for substitute parts?

A: Substitute parts are available in multiple packaging formats: Bulk (loose components), Cut Tape (CT), Tape & Reel (TR), and Tape & Box (TB). Selection depends on production volume and assembly equipment compatibility. All packaging options maintain identical electrical and optical specifications.

Q: Does forward voltage difference affect circuit design?

A: MV50152 operates at 1.6V typical forward voltage. Most substitutes operate at 1.9V to 2.1V. For current-limiting resistor circuits, recalculation is required: R = (Vsupply - Vf) / Iled. For example, a 5V supply with 10mA current requires 340Ω for MV50152 but 310Ω for 1.9V substitutes. Verify resistor values for your specific supply voltage.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed (HLMP series, SLR-56 series, LTL-4214) are ROHS3 compliant. The original MV50152 is obsolete and ROHS status is not specified. Compliance verification is recommended for regulated applications.

Q: What is the difference between clear and diffused lens transparency?

A: Clear lens (MV50152, HLMP-3366, SLR-56 series, LTL-4214) provides sharp light output with defined viewing angle. Diffused lens (HLMP-3351 series) scatters light for broader, softer illumination. Optical appearance differs significantly; application requirements determine appropriate selection.

Q: Can I use HLMP-D155 for low-power applications?

A: HLMP-D155 operates at 1mA test current, the lowest among substitutes, making it suitable for battery-powered or ultra-low-power designs. Forward voltage is 1.7V, closest to MV50152's 1.6V. Brightness is 10mcd, higher than MV50152's 2mcd. Narrower 24° viewing angle and increased height (12.44mm) require mechanical verification.
